Effects of Nutrition Education and Exercise Program on Obesity Index and Behavioral Modification in Moderate Obese Women: Myung Hee Chang, Su Jin Jung; Korean J Community Nutr 2018;23(4):318-332. Published online August 31, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.4.318

OBJECTIVES
The purpose of this study was to investigate the behavioral modification of obese adults who underwent nutritional and physical activity education. Twenty obese females, aged 20â€“60 years old, with BMIs (Body Mass Index) >30 or body fat (%) >40 were subjected to this study.
METHODS
The physical activity education program consisted of doing exercise in a gymnasium together or home exercise. Dietary attitudes and dietary intakes were assessed using weight control, physical activity, and eating habits. The nutrition-exercise educational period was 12 weeks.
RESULTS
After the study period, there was significant improvement in physical activity and eating habits score. Furthermore, there was a significant increase in the dietary intakes of fiber, iron, potassium, vitamin A, vitamin B6, and niacin. Blood pressure, blood glucose, and total cholesterol levels showed a tendency to decrease, but there was no significant difference. BMI, fat mass, abdominal circumference, and visceral fat levels were significantly reduced while muscle mass significantly increased.
CONCLUSIONS
This study suggests that behavioral modification by nutrition and physical activity education with feedback has positive effects on dietary intake and anthropometric biomarkers in obese adults. Therefore, lifestyle interventions of this kind could be recommended as a method for obesity management.

Metabolic Syndrome Status of Chinese Workers and Their Physical Profiles, Lifestyle Scores, and Nutrient Intakes: Chao Wang, Hokyung Ryu; Korean J Community Nutr 2017;22(1):63-73. Published online February 28, 2017; DOI: https://doi.org/10.5720/kjcn.2017.22.1.63

Abstract PDF PubReader: OBJECTIVES
This study was conducted to survey the related factors of metabolic syndrome of Chinese workers aged 20 years and above.
METHODS
The study was conducted at three locations in Shandong, China, currently working and took the physical examination (PE) within one year in the area as target participants. Personal characteristics, physical and biochemical results based on the PE, lifestyle habits, and food intake of the participants were used to analyze the relationship with metabolic syndrome.
RESULTS
Results showed that overall, thirty-one subjects (22.5%) had metabolic syndrome, twenty males (32.7%) and eleven females (14.2%). Metabolic syndrome was related to age, gender, educational level and occupational type with more risk in male (P < 0.05), people of older age (P < 0.001), low educational level (P < 0.05) and nonoffice workers (P < 0.01). According to the life style scores, lifestyle evaluation showed specifically alcohol consumption and smoking (P < 0.001) and stress management (P < 0.05) as important factors that were associated with the metabolic syndrome. High calorie (P < 0.01) and carbohydrate (P < 0.01) intakes were observed on male participants with metabolic syndrome in comparison to the non-metabolic syndrome but no significant difference on female participants.
CONCLUSIONS
This results of this study can be used as significant supporting data to prevent and control metabolic syndrome in Chinese workers.

A Comparison of Sources of Sodium and Potassium Intake by Gender, Age and Regions in Koreans: Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012: Yang Hee Park, Sang Jin Chung; Korean J Community Nutr 2016;21(6):558-573. Published online December 31, 2016; DOI: https://doi.org/10.5720/kjcn.2016.21.6.558

Abstract PDF PubReader

OBJECTIVES
The purpose of this study was to evaluate the main sources of dietary sodium and potassium intake in Koreans by gender, age and regions.
METHODS
We used the data from 2010-2012 KNHANES. A total of 20,387 subjects aged 8 years and older were included. Intakes were compared by gender, age (8-18, 19-49 and >50 years) and geographical regions in Korea. Dishes were classified into 28 dish groups based on cooking methods. Statistical analysis was performed by using the SAS 9.3 and SUDAAN 11.0.1 software.
RESULTS
The mean sodium intake of Koreans was 4866.5 Â± 35.9 mg/day, which was 2.4 times higher than the adequate intake (AI) of sodium for Koreans. We found that daily sodium intakes were significantly different by age, gender and regions. Men and aged over 50 years had significantly higher sodium intake than women and other age groups. The mean potassium intake in Koreans was 3002.2 Â± 19.4 mg/day and daily potassium intakes were significantly different by age, gender and regions. Women and age 50 years and over had significantly higher potassium intakes than men and other age groups. The average Na/K ratio was 2.89 Â± 0.01 and was highest in men and in the age group of 19-49 years. The major sources of dietary sodium were soup and stew, followed by Kimchi, noodles and dumpling, pickled vegetables and seasonings, which represented 63.1 % of total sodium intakes. Soup and stew or Kimchi were the primary sources of dietary sodium intake. The major sources of dietary potassium were cooked rice, followed by soup and stew, Kimchi, fruits and beverages.
CONCLUSIONS
Sodium and potassium intakes and the major sources of those were significantly different by gender, age groups and regions. Therefore, different approaches based on gender, age and regions are needed to decrease sodium intake and increase potassium intake.

OBJECTIVES
This study was performed to investigate the body image, food habits, nutrition knowledge, food intake frequency, nutrient intakes of female university students in Masan.
METHODS
Two groups (n = 302, nutrition major: 147, non-major: 155) were classified into underweight, normal weight and overweight/obesity groups according to BMI respectively.
RESULTS
Height and weight of all subjects were 161.5 cm, 53.2 kg and were 161.5 cm, 55.1 kg, 161.5 cm, 51.3 kg in major and non-major female students, respectively. The BMI and body weight were significantly different (p < 0.001). Significantly higher proportions of underweight students in both study groups had perceived as 'normal' or 'fat' (p < 0.001). Higher proportion of the subjects skipped breakfast and main reason was no time to eat. Nutrition knowledge score was significantly higher in major than in non-major subjects (p < 0.001). Fish intake frequency score was significantly higher in non-majors, while the vegetable intake frequency score was significantly higher in majors. Nutrient intakes were significantly higher the majors compared to non-majors, particularly the intake of calcium (p < 0.05), zinc (p < 0.001), vitamin C (p < 0.001) and vitamin E (p < 0.01). Subjects in both groups did not have adequate nutrient intakes compared to KDRIs. BMI showed a positive correlation with body image, body weight and nutrition knowledge score (p < 0.01).
CONCLUSIONS
These results suggest that systematic nutrition education program which can be applied in real life is important for the formation of correct choices of food and good eating habits.

A Study on the Sodium and Potassium Intakes and Urinary Excretion of Adults in Busan: Hwa Jae Lim; Korean J Community Nutr 2012;17(6):737-751. Published online December 31, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.6.737

Abstract PDF PubReader

The purpose of this study was to assess sodium and potassium intakes and urinary excretion of adults in Busan and to evaluate the relationship of urinary sodium/potassium excretion (UNa/UK) to the status of anthropometric, blood pressure, urine analysis, and nutrient intake of subjects. Nutrient intake by 24-h recall, 24-h UNa/UK were measured with 87 adults aged 20-59 yrs (42 men and 45 women). The mean intakes of sodium and potassium were 3915.4 mg and 3093.9 mg, respectively. The mean 24-h UNa/UK was 3457.0/1680.4 mg. UNa showed significant positive correlations with sodium intake (p < 0.001, p < 0.001), sodium/potassium ratio (p < 0.001, p < 0.01), UK (p < 0.001, p < 0.001), and UNa/UK ratio (p < 0.05, p < 0.01) in men and women and with age, BMI, systolic blood pressure (SBP) and diastolic blood pressure in women (p < 0.05, p < 0.05, p < 0.05, p < 0.05). The UK showed significant positive correlations sodium intake (p < 0.001, p < 0.001), UNa (p < 0.001, p < 0.001) in men and women and with sodium density in men (p < 0.001) and with age, intakes of protein and potassium in women (p < 0.01, p < 0.05, p < 0.05). Mean SBP was lowest in the second quartile and highest in the fourth quartile of UNa. Mean UNa in the second, third, and fourth quartiles were 2821.1 mg, 3621.3 mg, and 5456.4 mg, respectively. Mean SBP in the second, third, and fourth quartiles were 115.8 mmHg, 120.7 mmHg, and 125.9 mmHg, respectively. Based on the results, UNa was related to sodium intake, UK, and SBP. We conclude that nutritional education for the reduction of high sodium intake is needed in the general population to prevent and control adverse blood pressure levels.

The Comparison of Growth and Nutrient Intakes in Children with and without Atopic Dermatitis: Seung Joo Park, Jae Sun Lee, Kangmo Ahn, Sang Jin Chung; Korean J Community Nutr 2012;17(3):271-279. Published online June 30, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.3.271

Abstract PDF PubReader

The prevalence of atopic dermatitis (AD) has increased recently all over the world. Several studies worldwide reported growth retardation associated with AD, but few studies were reported in Korea. Therefore, the objective of this study was to identity the differences in growth and nutrient intakes between Korean children with and without AD. The participants were 71 AD children and age, gender-matched 81 control children aged 10 to 36 months. Demographic information was gathered by questionnaires. Height and weight were measured at clinic and health centers. Height and weight for age, and weight for height were converted as deviation in Z scores using World Health Organization Standard. A 24 hour dietary recall method was performed to estimate nutrient intakes. A higher percentage of AD children had insufficient energy and intakes of calcium, phosphorus, iron, zinc and vitamin B2 , defined as intakes lower than 75% of the Dietary Reference Intakes for Korean, compared to the control group (P < 0.001, P < 0.001 0.001, P = 0.003, P = 0.001, P = 0.014, P = 0.001, respectively). The percentages of children with height and weight for age Z score below than-1 (stunted) were significantly higher in the AD group (P < 0.001 0.001 and P < 0.001 0.001, respectively). Multiple food restriction, defined as > or = 3 food elimination, was associated with insufficient energy and intakes of calcium, phosphorus, iron, zinc, vitamins A and B2 . In conclusion, children with AD need regular nutrient assessment and education about alternative food choices to avoid r food elimination in order to prevent growth retardation or inadequate nutrient intakes. Further longitudinal studies for growth and nutrient intakes should be performed to understand the patterns of growth in children with AD.

A Study of Nutrient Intakes, Blood Lipids and Bone Mineral Density according to Obesity Degree by Percentage of Body Fat and Age between Male and Female Teacher in Jeonbuk Province, Korea: Hye Soon Chang; Korean J Community Nutr 2012;17(1):49-68. Published online February 29, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.1.49

Abstract PDF PubReader

The purpose of this study was to compare nutrient intakes, blood lipids and bone mineral density of male (n = 59) and female (n = 172) teachers according to the obesity index by percentage of body fat and age. The energy intakes of obesity group were higher than normal group in male (p < 0.05), but were not significant in female. The protein intake ratio among three energy nutrients for male was higher than female (p < 0.001), and lipid intake ratio of obesity group in female was a little higher than male that was not significant. TC, LDL, TC/HDL, risk of coronary heart disease, blood glucose and blood pressure of obesity group were higher than normal group in female (p < 0.01 ~ p < 0.001), but were little significance in male. Risk of coronary heart disease was affected by gender (p < 0.001), obesity degree (p < 0.01), age (p < 0.001), and interaction of gender and age (p < 0.001). Blood glucose was affected by obesity degree (p < 0.05), but was not affected by age. T-scores of forearm for female (= -1.42) were lower than that of male (= -0.95), and T-scores of obesity group in male (= 0.12) were higher than that of normal group (= -0.33) but were not significant in female. The T-scores of forearm for female were affected by age (p < 0.05) and gender (p < 0.01), but calcaneus was not affected by gender. These results suggest lipid intake ratio should be balanced for obesity group in female. Nutritional education for treatment obesity to prevent hyperlipidemia and arteriosclerosis is necessary for obesity group and older age groups. T-scores of forearm were lower than calcaneus, so arm exercise would be especially required to prevent osteoporosis for older age women groups.

The Difference of Perception about Nutritional Problems and Food intakes, Nutrition Knowledge Score and Realities of Nutrition Education between Parents and Preschool Teachers: Joo Hee Lee, Eun Jung Kang, Changim Kim; Korean J Community Nutr 2011;16(6):636-646. Published online December 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.6.636

Abstract PDF PubReader

This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (chi2 = 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (chi2 = 8.892, p = 0.030), fish (chi2 = 32.241, p = 0.000), beans (chi2 = 14.770, p = 0.005), vegetables (chi2 = 12.706, p = 0.013), fruits (chi2 = 14.438, p = 0.006) and milk & dairy products (chi2 = 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

Egg Consumption and Prevalence of Metabolic Syndrome in Korean Adults: Based on 2007-2008 Korean National Health and Nutrition Examination Survey: Hyo Jin Kim, Kyong Park; Korean J Community Nutr 2011;16(3):364-374. Published online June 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.3.364

Abstract PDF PubReader

There is a great public concern that higher consumption of eggs may increase the risk of chronic disease due to high levels of cholesterol in eggs. In contrast to this concern, limited studies have examined this relationship, and the study results have been inconsistent. This study was to evaluate the cross-sectional associations between egg consumption, blood markers and metabolic syndrome in Korean adults. We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Egg intakes were assessed using a food frequency questionnaire. Metabolic syndrome was ascertained using criteria of the NCEP ATP III (2001) and abdominal obesity criteria of the WHO. In 5,548 subjects, 937 subjects were defined as having metabolic syndrome. In linear regression models, subjects reporting one or more egg consumption per day had significantly lower levels of triglyceride, fasting blood glucose and blood pressure, and a higher level of HDL cholesterol, compared to those who rarely consumed eggs (P-trends < 0.05). After adjustments for potential confounding factors, the associations were no longer significant except for total cholesterol, showing higher levels with frequent egg consumption. More frequent intakes of egg (1 egg or more/day) were associated with lower risk of metabolic syndrome in a logistic regression model (OR: 0.69, 95% CI: 0.50-0.96), but this association also became insignificant after adjustments for multiple confounding factors (OR: 1.05, 95% CI: 0.71-1.57). In healthy Korean adults, frequent intakes of eggs did not adversely affect the risk of metabolic syndrome. Further studies are needed to confirm this finding.

Effect of School Lunch Menu Intervention through Calcium Enriched Menus on Nutrient Intakes of High School Girls: Eon Kyoung Lee, Young Sun Choi, Bok Seon Bae; Korean J Community Nutr 2011;16(2):265-277. Published online April 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.2.265

Abstract PDF PubReader

This study was conducted to improve the nutritional status of high school girls via lunch menu intervention. Surveys were carried out twice to evaluate basal status and status after lunch menu intervention. In the first survey nutrient intakes of 24-hour and school lunch were each estimated by 24-hour recall dietary survey and self-recording, respectively. Calcium intake was the lowest among nutrients, and stir-frying was the most preferred cooking method. Five dishes of school lunch menus which were included in the first survey were replaced with recipes containing foods with higher calcium level; anchovy stir-fried with red pepper paste, anchovy stir-fried with almond, pork stir-fried with shredded kelp, crab meat soup, and tteokbokki with cheese. In the second survey calcium intake from school lunch was significantly (p < 0.001) increased from 45.5% to 50.2% of one thirds of recommended intake (RI) after calcium enriched lunch menu intervention. Intakes of vitamin A and E were also significantly increased, whereas those of energy, thiamin, and vitamin C were decreased. Index of nutritional quality values of nutrients of 24-hour intakes (except thiamin, vitamin B6, vitamin C) is increased by intervention; however, those of calcium, folic acid, iron are still very low. Even though this study shows a possibility of improving nutrient intakes of students through school lunch menu intervention, lunch intervention by itself is not enough action to improve nutritional status of micronutrient for adolescents.

A Study on the Calcium and Sodium Intakes and Urinary Calcium Excretion of Adults in Busan: Hwa Jae Lim; Korean J Community Nutr 2011;16(2):215-226. Published online April 30, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.2.215

Abstract PDF PubReader

The purpose of this study was to assess calcium and sodium intakes and urinary excretion of adults in Busan and to evaluate the relationship between urinary calcium excretion (UCa) and the status of anthropometric, blood pressure, urine analysis, and nutrient intake of subjects. Nutrient intake by 24 hr recall, 24 hr urinary calcium and sodium excretion (UNa) were measured with 87 adults aged 20-59 yrs (42 men and 45 women). The mean calcium intake was 88.0% for men and 103.0% for women of Recommended Intake. The mean sodium intake was 283.4% for men and 250.5% for women of Adequate Intake (AI). The mean 24hr UCa was 127.4 mg in men and 107.3 mg in women. The mean 24 hr UNa was 3650.6mg in men and 3276.4mg in women. The intake and urinary excretion of calcium and sodium were not significantly different by gender. UCa showed significantly positive correlations with sodium intake and UNa in men (p < 0.001, p < 0.05) and women (p < 0.001, p < 0.001) and with age, systolic blood pressure (SBP) and sodium density in women (p < 0.05, p < 0.05, p < 0.01). The UCa/creatinine showed significantly positive correlations with age, sodium intake, sodium density, and UNa in women (p < 0.05, p < 0.01, p < 0.01, p < 0.01). When UCa was stratified into quartile (Q1-Q4), age, SBP, UCa, UNa, sodium intake, and AI percentage of sodium (p < 0.01, p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.001) were significantly higher in Q4. The mean intake and AI percentage of sodium in Q4 were 4768.8mg and 329.0. Based on the results, UCa was related to age, SBP, UNa, and sodium intake. Therefore, nutritional education of decreasing sodium intake for decreasing UCa is needed.

Associated Factors with Severity of Atopic Dermatitis in Children: Jae Sun Lee, Sunmi Jo, Heechul Lee, Kangmo Ahn, Sang Jin Chung; Korean J Community Nutr 2010;15(6):776-782. Published online December 31, 2010

Abstract PDF: The prevalence of atopic dermatitis (AD) has increased over the past decades. A variety of factors are related to the development of atopic dermatitis, including genetics and environmental factors. The purpose of the study was to examine factors associated with severity of atopic dermatitis in 104 children aged 6-60 months. To investigate the association between severity and other factors children were divided into two groups, mild (n = 62) and severe (n = 42) groups, based on SCORAD index which measures the severity of atopic dermatitis. Results showed that family history, family's smoking, period of having AD and the levels of the serum total IgE were significantly higher in severe group. More than 6 months of breastfeeding and weaning after 6 month were not associated with severity of AD, but the number of food eliminated was associated with severity. Only vitamin C intake was significantly different by severity after adjusting for energy intake, family history, family's smoking and period of having AD (p = 0.033). There was no association between the severity of atopic dermatitis and growth of children. This study concluded that the severity of atopic dermatitis was associated with family history, family's smoking, period of having AD, children's serum total IgE, and vitamin C intakes. The result of this study should provide the significant information for better management of AD.

Health Status and Nutrient Intakes of 5th Grade Elementary Students in Seoul and Gyeonggi Province: Ok Hyun Kim, Hyun Ah Park, Young Gyu Cho, Kyoung Woo Kim, Yangim Hur, Ji Hyun Song, Jae Heon Kang; Korean J Community Nutr 2010;15(6):717-726. Published online December 31, 2010

Abstract PDF: This study was conducted to investigate health status and nutrient intakes among 5th grade elementary students at Korea Centers for Disease Control and Prevention 2010. This study was cross-sectional study on 1,384 children (687 boys, 697 girls) from nine elementary schools located in Seoul and Gyeonggi province. The average height, weight and BMI were 145 cm, 40.6 kg 19.2 kg/m2 for boys and 145.4 cm, 38.2 kg, 18.0 kg/m2 for girls. The prevalence of overweight and obesity were 11.3%, 5.2%, respectively. Serum AST, ALT, glucose, HDL-Cholesterol and RBC levels were significantly higher, while TG levels was significantly lower for boys than for girls. The average energy intake was 1772.4 kcal, which was 98.7% of Estimated Energy Requirement (EER). The boys consumed more energy intake (1800.4 kcal) than the girls (1744.7 kcal). Also, they took insufficient calcium and folate (69.1% and 83.3% of Recommended Intake (RI)) and excess sodium (297.6% of Adequate Intake (AI)) and 85.1% of the subjects had breakfast everyday. In general, the proportion of the children who consumed fruits and vegetables at least once or more a day was low. There was a higher proportion of children in boys who had ramyun and milk with sufficient physical activity than those in girls. As a result of this study, we can find risk factors on obesity and metabolic disorders, and the results can be used for an evidence of nutrition education program and the intervention program.

Assessment for Nutrient Intakes in Korean Women according to Obesity and Metabolic Syndrome: Hye Kyung Chung, Ju Hee Kang, Min Jeong Shin; Korean J Community Nutr 2010;15(5):694-703. Published online October 31, 2010

Abstract PDF: Recent studies have reported that a subset of obese individuals who were metabolically healthy but obese had more favorable clinical outcomes than obese subjects with metabolic disturbances. The purpose of this study was to evaluate the distribution and agreement of obesity subtypes according to body mass index (BMI) and metabolic syndrome (MS). Furthermore, we examined the differences of nutrient intake among the groups. Data was analyzed for 1,095 female subjects older than 40 years using Korean National Health and Nutrition Survey in 2008. The degree of obesity was classified by two methods, using BMI (obese > or = 25 kg/m2, not obese < 25 kg/m2) and MS (meet > or = 3 criteria among 5 index: waist circumference, triglyceride, glucose, HDL-cholesterol and blood pressure). Subjects were divided into 4 groups according to 2x2 cross table: non-obese without MS, non-obese with MS, obese without MS and obese with MS. Nutrient intakes were compared among 4 groups. The results showed that the proportions of non-obese without MS, non-obese with MS, obese without MS and obese with MS were 47.6%, 13.6%, 16.6%, and 22.2% of total subjects, respectively. The agreement (kappa value) of two methods was 0.354 (fair) in total subjects, 0.365 (fair) in 40-60 year old subjects and 0.304 (fair) in > or = 61 year old subjects. In > or = 61 years old subjects, intakes of percentage energy from carbohydrate, percentage of energy from fat, calcium, phosphorous, sodium, vitamin A, carotene, thiamine, riboflavin and niacin were significantly different among the groups. In contrast, the subjects of 40-60 years old, no differences in nutrient intakes were observed. In conclusion, there were differences in nutrient intakes among the groups subdivided by obesity and MS, especially in elderly female subjects. Individualized dietary guideline for subtype of obesity will be needed to treat metabolic disturbance of obesity.

A Study on Vegetable Intakes and Dietary Habits of Middle School Students in Chungnam: Hyun Sun Cho, Myung Hee Kim, Mi Kyeong Choi; Korean J Community Nutr 2010;15(4):525-535. Published online August 31, 2010

Abstract PDF: The purpose of this study was to provide basic data for nutritional education for juveniles' desirable vegetable intake by analyzing their vegetable intake, dietary habit and nutrient intakes according to gender of middle school students in Chungnam. The average age of the subjects was 15.0, height was 162.5 cm, weight was 53.5 kg and their average BMI was 20.1 kg/m2. The frequency of eating supper in girls was lower than that in boys. Many respondents answered that a meal-time was 10~20 minutes. Without gender difference, more than 90% respondents thought that vegetables were good for health. As for the preference of vegetable, subjects responded, "I am in the middle", "I like them", "I dislike them", "I like them very much", and "I dislike them very much" in order, without gender difference. The frequent eaten leaf vegetable was Chinese cabbage, the frequent eaten fruit vegetable was cucumber, and the frequent eaten root vegetable was radish. The favorite leaf vegetable was lettuce, the favorite fruit vegetable was corn, and the favorite root vegetable was sweet potato. The preference degrees of taro and ginger were very low. The reasons why they liked a vegetable were that it was delicious and they ate it at home often. In addition, the reason why they disliked vegetables was that they are untasty in flavor or texture and it showed that many students had a prejudice that vegetables were untasty. The intakes of plant protein, dietary fiber, ash and INQs of dietary fiber, calcium, vitamin C, folate, vitamin E in the group with high preference of vegetables were significantly higher than those of low preference group. The study results indicate that intake frequency and preference of root vegetables in juveniles are low and the major reasons of these results are taste and eating experience of vegetables. In addition, the intake amounts of dietary fiber and folate are poor in the subjects with low preference of vegetables. Therefore, families and schools should make efforts that juveniles can recognize the importance of vegetable intake and select various vegetables properly through the development of cooking methods and systematic nutrition education.

Abstract PDF: This study was performed to assess the physical activity, food habit and nutrient intakes by gender and age groups in 193 adults aged 20-59 years (84 men and 109 women) in Pusan. Data for physical activity and dietary survey was assessed by a questionnaire and 24hr recall method. The mean BMIs of men and women were 24.0 and 22.2 respectively and BMI of women in the 20-29 years group (20.9) was significantly lower than that of women in the 30-49 and 50-59 years group (22.7, 23.2) (p < 0.01). 56.0% for men and 44.0% for women exercised regularly. The mean exercise duration per once of men (69.7 minutes) was significantly higher than that of women (52.4minutes) (p < 0.01). The mean exercise duration per day was 36.0 minutes for men and 29.9 minutes for women. 67.9% for men and 78.0% for women often skipped meals and 68.4% for men and 69.4% for women skipped breakfast in the main. The mean energy intake of men was 2067.2 kcal and that of women was 1783.1 kcal comprised of 87.2% and 92.1% of the Estimated Energy Requirements (EER). The mineral intakes of men and women were over Recommended Intake (RI) and Adequate Intake (AI) except calcium and potassium. The mean calcium intake was 88.3% for men and 84.0% for women of RI. The mean potassium intake was 63.3% for men and 59.2% for women of AI. The mean vitamin intakes of men and women were over RI and AI except vitamin C and folic acid. The mean vitamin C intake was 92.5% for men and 85.6% for women of RI. The mean folic acid intake was 76.6% for men and 70.0% for women of RI. The mean energy, protein, sodium and zinc intakes of men were significantly higher than those of women (p < 0.01, p < 0.05, p < 0.05, p < 0.05). The mean vitamin B6, vitamin C and folic acid intakes of men in the 20-29 years group were significantly lower than those of men in the 30-49 and 50-59 years group (p < 0.01, p < 0.05, p < 0.05). For energy, proportions of subjects with intake levels less than 90% EER were 64.3% for men and 56.0% for women. For calcium, proportions of subjects with intake levels less than Estimated Average Requirement (EAR) were 52.4% for men and 59.6% for women. For folic acid, proportions of subjects with intake levels less than EAR were 78.6% for men and 83.5% for women. For iron and phosphorus, proportions of women (36.7%, 14.7%)with intake levels less than EAR were significantly higher than those of men (6.0%, 1.2%) (p < 0.01, p < 0.001). For men, age was positively correlated with intakes of potassium, vitamin B6, vitamin C and folic acid (p < 0.05, p < 0.05, p < 0.05, p < 0.01). For men, weight showed significantly negative correlations with intakes of carbohydrate, phosphorus, potassium, zinc, vitamin B6 and folic acid (p < 0.01, p < 0.05, p < 0.05, p < 0.05, p < 0.01) and BMI showed significantly negative correlations with protein, lipid, phosphorus, potassium, zinc, vitamin E and folic acid (p < 0.05, p < 0.05, p < 0.05, p < 0.05, p < 0.05, p < 0.05, p < 0.05) For men, exercise duration per once showed significantly positive correlations with intakes of calcium, phosphorus, potassium, zinc, vitamin B1, vitamin B2, niacin, vitamin C and folic acid (p < 0.01, p < 0.05, p < 0.01, p < 0.05, p < 0.05, p < 0.01, p < 0.01, p < 0.01, p < 0.05). Therefore, nutritional education for adult health management is needed by gender and age groups.

Comparative Study on Nutrients Intake, Physical Activities and Bone Mineral Density of Specialized Game High School Students according to Obesity Level: Yun Kyoung Oh, Cheongmin Sohn; Korean J Community Nutr 2010;15(3):393-402. Published online June 30, 2010

Abstract PDF: The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily" 2.48, "Do not skip breakfast" 2.29, "Eat a variety of vegetables, fruits, dairy products daily" 2.25, "Drink water instead of beverage" 2.10, "Choose less fried foods" 2.09 and "Maintain healthy weight" 1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin B2 was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.

Changes of Obesity Index, Serum Lipid Profiles and Nutrient Intakes in Obese Children after the Weight Control Program of Nutrition Education: Eun Ju Lee, Kyung Hee Kim; Korean J Community Nutr 2010;15(1):61-72. Published online February 28, 2010

Abstract PDF: The purpose of this study was to evaluate the effect of a weight control program on anthropometric values, serum lipid profiles and nutrient intakes. The subjects of this study were 38 obese children (boy : 17, girl : 21) with obesity index over 120%. The weight control program for obese children included nutritional education (50 min) and exercise (50 min) for 10 weeks. The nutrition intakes of the children were surveyed before and after the weight control program by 24hr recall test. The BMI, Rohrer Index, Obesity Index, WHR (Waist - Hip ratio) and body fat(%) were significantly decreased after completion of the weight control program. The total cholesterol and HDL-cholesterol of subjects were significantly increased after the weight control program. Distribution of serum lipid profiles was slightly changed. The energy intakes were significantly decreased (p < 0.001). from 1760.8 kcal to 1435.2 kcal. In addition, the intakes of P, Zn, retinol, vitamin B1, vitamin B2, vitamin E and niacin were significantly decreased. while intakes of vitamin C and folate were increased. Calcium and folic acid were upper 25% of subjects, under EAR(Estimated Average Requirements) intake before the weight control program. The distribution of energy intakes was significantly changed into positive status; fat percentage was decreased 26.3% to 22.1% (p < 0.01). Carbohydrate was increased 58.6% to 61.2% (p < 0.05). Meal distribution of energy intakes was changed; calorie percentage from lunch significantly increased from 32.2% to 38.3%. Calorie percentage from snack significantly decreased from 17.7% to 13.5%. In conclusion, weight control program for 10 weeks is effective in obesity index and nutrient intakes although serum lipid values were a little changed.

Association of Serum Lipids and Dietary Intakes with Serum Adiponectin Level in Overweight and Obese Korean Women: Mi Young Lee, Jung Hee Kim; Korean J Community Nutr 2010;15(1):27-35. Published online February 28, 2010

Abstract PDF: This study was done to investigate the association of blood clinical parameters and dietary intakes with serum adiponectin level. Athropometric measurement, dietary intakes, serum lipids and adiponectin levels were examined in 160 overweight and obese women. The subjects were divided into 5 groups by quintile according to serum adiponectin level. Weight, BMI, waist circumferences and waist/hip ratio of the highest quintile group were significantly lower than those of the lowest quintile group. Serum lipid analysis showed a significant higher level of TG, LDL-cholesterol, LDL/HDL ratio, AI, and serum hs-CRP in the lowest quintile group. Similarly, correlation data also showed that serum adiponectin level was positively correlated with serum HDL-cholesterol level (p < 0.01) and was negatively correlated with BMI (p < 0.01), waist circumferences (p < 0.01), waist/hip ratio (p < 0.01), systolic (p < 0.01) and diastolic blood pressure (p < 0.05), TG (p < 0.01), LDL-cholesterol (p < 0.05), LDL/HDL ratio (p < 0.05), AI (p < 0.01), Homa-IR (p < 0.01), hs-CRP (p < 0.05) and leptin (p < 0.05). Dietary intake data showed that protein intake was significantly lower in the highest quintile group compared to the lower quintile groups while intakes of vitamin C was significantly higher in highest quintile group after adjustment by BMI, waist and energy intake, In addition, the highest quintile group had higher fiber intakes than the lower quintile groups. These results might suggest that a diet high in fiber and vitamin C and low in protein for obese patients would better be recommended to improve adiponectin level. However, further research is needed to elucidate the association of dietary intakes or dietary patterns and serum adiponectin level.

Nutrient Intakes and Blood Lipids According to Obesity Degree by Body Fat Percentage among Middle-Aged Women in Gunsan City: Hye Soon Chang; Korean J Community Nutr 2010;15(1):15-26. Published online February 28, 2010

Abstract PDF: The purpose of this study was to compare nutrient intakes and blood lipids of middle-aged women according to the obesity index by %Fat. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat): normal weight (18% ~ < 28%), overweight (28% ~ < 33%) and obesity (over 33%). Nutrient intakes were evaluated based on questionnaires of 24 hours recall method and blood lipids were analyzed by blood analyzer. The results were as follows. 1) Nutrient intakes were that carbohydrates and fat intakes in obesity group were higher than normal and overweight group but the difference was not significant, and protein intake rate was similar all groups. The intake rate of calcium was higher in normal group than obesity group (p < 0.05), and obesity group ingested under dietary reference intakes. The intake rate of iron was higher in obesity group than normal group (p < 0.05). 2) TG, TC, VLDL and TC/HDL in obesity group were higher than normal group (p < 0.001). The attack rate of coronary heart disease in obesity group is higher than normal group (p < 0.01), LDL, blood glucose and blood pressure in obesity group were higher than normal group (p < 0.01), and HDL was a little higher in normal group than obesity group, but the difference was not significant. 3) The correlation of anthropometric measurements, blood glucose, blood lipid, and blood pressure had significant results. Weight was associated positive level with blood glucose, blood lipid and blood pressure. Waist and WHR were associated positive level with blood glucose and blood lipid but weren't associated with blood pressure. BMI was associated positive level with blood glucose, blood lipid and blood pressure, %Fat was associated positive level with blood lipid and blood pressure, but wasn't associated with blood glucose. These results suggest that the decrease of waist on blood glucose control is better than decrease of % Fat and BMI, the decrease of %Fat and BMI on blood pressure control is better than decrease of waist, and the decrease of %Fat on blood lipid control is better than waist and BMI. The nutritional education for obesity treatment must perform to analyze the blood and assess the obesity degree by %Fat, waist and BMI before nutritional education, so the obesity treatment will be effectively.

Effects of Weight Control Program on Nutrient Intakes and Physical Fitness in Obese Korean Adult Women: Eun Ju Lee; Korean J Community Nutr 2009;14(6):756-766. Published online December 31, 2009

Abstract PDF: This study was conducted to investigate the effects of weight control program on nutrient intakes and physical fitness of Korean obese adult women. The subjects of this study were 33 obese adult women aged 30-65 years residing in Seoul. The weight control program for obese women included nutrition education, cognitive behavioral therapy and exercise for 12 weeks. There were significant decrease (p < 0.001) of blood pressure and atherogenic index of obese women after the weight control program. Energy intake was significantly decreased (p < 0.001) from 1556.9kcal to 1044.9kcal after 12 weeks of the weight control program. Also protein, fat and carbohydrate intakes were significantly decreased. The ratio of energy intakes per day for the subjects was carbohydrate 64% : protein 16% : fat 20%. The frequency of vegetables intakes was significantly increased (p < 0.05) and there were no significant differences in other food groups. After the weight control program, muscle endurance, flexibility, balance and explosive muscular strength of subject's physical fitness were significantly improved. These results suggest that the weight control program for obese women may contribute to nutrient intakes reduction and improvement of physical fitness.

Dietary Behavior Factors for Desirable Nutrient Intakes of the Oldest-old Population in Sunchang County: Mee Sook Lee; Korean J Community Nutr 2009;14(6):699-709. Published online December 31, 2009

Abstract PDF: In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin B2 intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

The Anthropometric Status and Nutrient Intakes of Physical Education Majors and Non-major Male College Students: Hyun Ock Park, Hwa Jin Hyun, Kyung Hee Song; Korean J Community Nutr 2009;14(1):12-21. Published online February 28, 2009

Abstract PDF: The study was performed to investigate the relationship of regular exercise to body composition and nutrient intakes of male college students by comparing anthropometric measurements and one-day dietary intakes by 24-hour recall of physical education (PE) majors and non-major male college students. The subjects were 253 students residing in the Gyeonggi area. Only 64.1% and 32.1% of PE majors and non-major students exercised over 4 times a week and PE major students did stronger exercise than the non-major students did. Mean BMI and WHR (Waist Hip Ratio) of the two groups were not different. But percentages of body fat and lean body mass in PE major students were lower and higher, respectively, than those of non-major students. PE major students consumed significantly more energy and other nutrients except iron, niacin, vitamin C, and vitamin E than non-major students. Nutrients consumed less than KRDA was calcium in PE major students and energy, calcium, zinc, vitamin B12, folate, and vitamin C in non-major students. Mean adequacy ratio (MAR) of PE major students (1.00) was significantly higher than that of non-major students (0.94). Index of Nutritional Quality (INQ) of all nutrients except vitamin A of PE major students was also significantly higher than that of non-major students. Nutrients below 1.00 in INQ of both groups were calcium, zinc, vitamin B2, and folate. Our data supports that regular exercise may positively influence on body composition and increase diet quality in male college students. Therefore, an educational program focused on regular exercise along with proper dietary behavior would be needed.

Blood Lipid Levels, Nutrient Intakes and Health-Related Lifestyles of Industrial Male Workers According to Apolipoprotein E Polymorphisms: Yoo Kyoung Park, Sang Woon Cho, Ji Yeon Kang, Yun Mi Paek, Sook Hee Sung, Tae In Choi; Korean J Community Nutr 2008;13(5):713-722. Published online October 31, 2008

Abstract PDF: The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin B2 (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.

The Daily Intakes of Nutrients and Snacks of High School Smokers and Non-Smokers: Young Mi Song, Jang Il Han, Seong Ai Kim; Korean J Community Nutr 2008;13(4):476-488. Published online August 31, 2008

Abstract PDF: This study investigates the relationship of smoking on daily intake of nutrients and snacks in the Chungnam and Daejeon high school students. Up to date scientific nutrition education and counseling programs in the regular school system is needed for a professional nutrition education teacher. The primary objective of this study was to provide useful information to nutrition education teachers. A survey was conducted with 400 high school students in the Chungnam and Daejeon areas. 381 out of 400 questionnaires were analyzed with SPSS 12.0K. The subjects were composed of 49.8% male, 50.1% female and 40.9% regular high school students, 59.1% business high school students and smokers 43.1%, non-smokers 56.9%. 43.4% of smokers had been smoking since middle school. On analysis of daily nutrient intakes, 16 out of 19 nutrients except animal calcium, Vitamin A and Vitamin C were much more consumed by the smoking group than the non-smoking group non-significantly. Especially vegetable fat and Vitamin E were higher in the smoking group than the non-smoking group(p < 0.05). The intake ratio of carbohydrates: protein: fat was similar in the two groups (smoking group 55 : 15 : 29, nonsmoking group 56 : 15 : 28). Intakes of Vitamin B1 and potassium in comparison with the Korean dietary reference intakes (KDRI) were under 50% in both groups. However, sodium was taken over 200% compared to KDRI in both groups. Intakes of Vitamin C in the smoking group were as low as 76.5% in comparison to KDRI. Smokers need to increase the intakes of Vitamin C considering that smokers need to intake Vitamin C two times than non-smokers. Nutrient intakes from snacks in the smoking group were higher than the non-smoking group. Nutrients that originated from snacks which took over 20% among daily nutrient intakes were 12 nutrients (energy, fat, carbohydrate, calcium, P, Fe, K, Vitamin B1, Vitamin B2, Vitamin C, Vitamin E, dietary fiber) in the smoking group compared to 7 nutrients (energy, vegetable protein, fat, carbohydrate, calcium, Vitamin B2, Vitamin C) in the non-smoking group. The smoking group was significantly paying more money for snacks each month than the non-smoking group was (p < 0.01). Periods of consumption were irregular in the smoking group(p < 0.05) and the smoking group was used to taking snacks in the morning compared to the non-smoking group. The smoking group preferred sweets and high calorie food over other snacks in comparison of the non-smoking group. The nonsmoking group had better eating habits than the smoking group

Nutrient Intakes Differences of the People Living Near the Nuclear Plant by the Household Income Level: Hye Sang Lee, Joung Won Lee, Wan Soo Kim, Dong Yean Park, Kyeong Hee Yu, Myoung Soon Park, Joo Han Kim; Korean J Community Nutr 2008;13(2):207-215. Published online April 30, 2008

Abstract PDF: This study was conducted to measure and evaluate the food and nutrient intakes of the people living near the nuclear plant and to investigate the relationship between the household income level and the food and nutrient intake patterns. A total of 552 cases (263 males and 289 females) were surveyed during the period from April 1 to December 21 of 2005. Dietary intake was measured by means of the 24-hour recall method. The data were analyzed using SPSS Windows (ver. 14.0). The household income level of the subjects was classified into two groups : Low income group (LIG; < or = 2,000,000 won) and high income group (HIG; > 2,000,000). The subjects at large had less energy and nutrient intakes than did the population in town and village who participated in the 2005 National Health and Nutrition Survey. The intake of calcium, zinc, vitamin A, riboflavin, vitamin B6, vitamin C, and folic acid was less than the Estimated Average Requirement in case of 50~95% of the subjects. The LIG consumed less beans, vegetables, fruits, meats, and beverages than did the HIG in male, while the LIG consumed less eggs and beverages than did the HIG in female. The LIG consumed less nutrients than did the HIG in male, except for carbohydrate, while the LIG consumed less nutrients including zinc, vitamin A, riboflavin, vitamin B6, vitamin C, folic acid than did the HIG in female. In addition, the LIG had higher percentage energy consumption from carbohydrate. These results suggest that higher food and nutrient intake is associated with higher income.

Food Intake Patterns and Blood Clinical Indices in Female College Students by HDL-cholesterol Levels: Ha Na Jung, Jung Hee Kim; Korean J Community Nutr 2008;13(1):100-110. Published online February 29, 2008

Abstract PDF: Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (< 50 mg/dL, n = 20), medium HDL-cholesterol (50< or =, < 60 mg/dL, n = 39) high serum HDL-cholesterol groups (60< or = mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate : protein : fat was 57 : 15 : 28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.

Nutrient Intakes and the Physical Activities of the Mentally Retarded Persons According to the Degree of Handicap Who Were Accommodated in Institutions in Andong Area: Jae Sung Kwon, Hye Sang Lee; Korean J Community Nutr 2007;12(6):790-797. Published online December 31, 2007

Abstract PDF: This study was conducted to evaluate the nutrient intakes and the physical activities of mentally retarded persons (MRPs) accommodated in welfare institutions. A total of 194 cases of MRPs (130 males and 64 females) were surveyed through interviews of the 35 caregivers of the institutions during the period from March 2 to 12, 2005. The mean age of the 2nd degree is the highest, and the duration of institution stay of the 2nd degree is the longest. There were no significant differences in height, weight, but there were still significant differences in BMI by the degree of handicap. The MRPs with the 1st degree handicap consumed less nutrients than the MRPs with 2nd or 3rd degree handicaps, except for vitamins C and E. The mean activity factor was 1.737 +/- 0.422 meaning 'active'. Among the comparative groups, the activity factor of the 2nd handicap degree MRPs was the highest. Note that the percentage of protein is the lowest in the case of the 1st degree handicap. The intake of the folic acid, in particular, was less than the Estimated Average Requirement (EAR) in case of all the MRPs while that of vitamin C, riboflavin and calcium was less than the EAR in case of 65~80% of the MRPs. MRPs with higher activity factors showed higher intakes of most nutrients except vitamin C. MRPs with higher marks in the 'balanced dietary habit' field showed more nutrient intakes. More consumption of vegetables and fruits by the MRPs was recommended. Also, more efficient dietary guidance was recommended for the MRPs.

Sodium Intakes of Korean Adults with 24-hour Urine Analysis and Dish Frequency Questionnaire and Comparison of Sodium Intakes According to the Regional Area and Dish Group: Sook Mee Son, Young Sook Park, Hwa Jae Lim, Sook Bae Kim, Yeon Seon Jeong; Korean J Community Nutr 2007;12(5):545-558. Published online October 31, 2007

Abstract PDF: This study was performed to assess the sodium intakes of Korean adults using a 24-hr urine analysis and dish frequency questionnaire (DFQ) according to each dish group and the regional area. The subjects of this study were comprised of 552 adults (male: 267, female: 285), aged 20-59yr residing in the metropolitan area (N = 200), Chungcheng-Do (N = 117), Jeolla-Do (N = 117), and Gueongsang-Do provinces (N = 118). The subjects were recruited from the residents who once participated or are participating in the various health programs offered by the public health center. The number of subjects who completed the 24-hr urine collection was 205 (male : 110, female : 95).The mean age and BMI of the subjects were 39.0+/-11.7 y and 23.1+/-2.9 kg/m2, respectively. The mean systolic and diastolic blood pressure was 119.5+/-15.4 mmHg, and 77.1+/-11.1 mmHg, respectively. Eighteen percent of the subjects responded that they are currently smoking, 36% drinking and 50.4% exercising. Twenty point six percent of the subjects were assessed as having hypertension according to their systolic or diastolic blood pressure(SBP > or = 140 mmHg or DBP > or = 90 mmHg) measurements in the present study. Salt intake of the subject estimated with 24-hr sodium excretion was 12.7 g/d (male : 13.4 g/d, female : 12.1 g/d) based on the sodium excretion rate as 82%. Salt intake estimated with DFQ was 14.7 g/d (male : 16.2 g/d, female : 13.4 g/d), 2 g more than the salt intake estimated with 24-hr urine analysis. The four dish groups that contributed most to the sodium intake in order were kimchi (I1571.4mg), soup and stew (1260.5 mg), fish and shellfish (706.3 mg) and noodle and ramyeon (644.3mg). Salt intake estimated with DFQ was the highest in the subjects of Gueongsang-Do (17.0 g/d), second highest Chungcheong-Do (16.4 g/d) and the lowest in the metropolitan area (13.0 g/d). Subjects of Gueongsang-Do showed the highest sodium intakes in most of the dish group, whereas subjects of the metropolitan area showed the lowest. Residents of Chuncheong-Do revealed the highest sodium intake with kimchi and ofJeolla-Do the higher sodium intake with the main dish (meat, fish and beans). The highest salt percentage of kimchi (3.0+/-0.8%) and soybean paste (14.5 +/-5.1%) were observed in Gueongsang-Do, whereas individuals of the metropolitan area were observed as having kimchi (1.6 +/-0.5%) and soybean paste (7.4 +/-1.6%) with the lowest salt percentage. Men were observed as having more salty kimchi (2.4 +/-0.1%) than women (2.1 +/-0.1%).

A Comparative Study of Nutrition Knowledge, Dietary Attitude and Nutrient Intakes of Dietitians and Non-Dietitians Working in the Chonnam Area: Bok Mi Jung, Mi Jeong Kim, Il Su Choi; Korean J Community Nutr 2007;12(3):284-298. Published online June 30, 2007

Abstract PDF: This study was performed by a comparative analysis of nutritional knowledge, dietary attitudes and nutrient intakes of dietitians and non-dietitians. The subjects of this study were 103 dietitians and 166 non-dietitians working in the Chonnam area. The general characteristics, nutrition knowledge and dietary attitudes of the subjects were surveyed using a self-administered questionnaire, and nutrient intakes were examined using 24-hour recall method. The results were as follows: Dietitian group (15.17+/-3.88) scored significantly (p < 0.0001) higher than non-dietitian group (13.34+/-3.31) in nutrition knowledge. Dietitian group (69.58+/-10.67) scored significantly higher on dietary attitudes than the non-dietitian group (63.97+/-11.18). The correlation between nutritional knowledge scores and dietary attitudes scores were statistically significance on job, age (20~39), education level (below university), marital status and work experience (2~5, above 10). The dietitian group was significantly higher than the non-dietitians in body weight and BMI of anthropometric data. The prevalence of obesity was 5.8% from the dietitian group and 6.6% from the non-dietitian group when judged by BMI and therefore obesity rate was significaltly (p < 0.001) different between the two groups. In case of the dietitian group, the average intake of vitamin A, vitamin B1, vitamin B6, niacin, vitamin E, phosphorous, zinc were above the Korean RDA whereas the average intake of vitamin C, calcium, iron, folic acid were below the Korean RDA. The average intake of most nutrients, except vitamin B1, vitamin B6, phosphorus, were below the Korean RDA in the non-dietitian group. Therefore the non-dietitian group needs nutrition education in order to improve their nutritional status.
