Intake of energy and macronutrients according to household income among elementary, middle, and high school students before and during the COVID-19 pandemic: a cross-sectional study: Chae-Eun Jeong, Heejin Lee, Jung Eun Lee; Korean J Community Nutr 2024;29(3):234-252. Published online June 30, 2024; DOI: https://doi.org/10.5720/kjcn.2024.29.3.234

Abstract PDF PubReader ePub: Objectives
This study examined the intake of energy and macronutrients among elementary, middle, and high school students according to household income before the COVID-19 pandemic (2016–2019), during the social distancing period (2020–2021), and after the social distancing measures were lifted (2022).
Methods
We included 5,217 students aged 5–18 from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2016 and 2022. Dietary intake was assessed using one-day 24-hour dietary recalls. We estimated the least squares means (LS-means) of intake according to household income for each period using a weighted linear regression model, adjusted for age and sex. Differences in LS-means between the periods were analyzed using the t-test.
Results
During the social distancing period, the LS-means of energy intake among students decreased significantly by 143.2 kcal/day compared to pre-pandemic levels (P < 0.001). Students from low-income households experienced a more pronounced decrease in energy intake (−379.1 kcal/day, P < 0.001) and macronutrient intake compared to those from other income groups. Energy intake at school significantly declined for all income groups during the social distancing period compared to before the pandemic. No significant changes in home energy intake were observed among low-income students, whereas there was an increase for students from higher-income groups. Before the pandemic, 8.5% of students from low-income households reported insufficient food due to economic difficulties; this figure rose to 21.3% during the pandemic.
Conclusions
During the pandemic, students from low-income families experienced significantly lower intake of energy and macronutrients compared to pre-pandemic levels. The most substantial reductions were noted among low-income students, largely due to the lack of compensation for decreased school-based intake with increased intake at home.

Micronutrients and prevention of cervical pre-cancer in HPV vaccinated women: a cross-sectional study: Chandrika J Piyathilake, Suguna Badiga, Nongnut Thao, Pauline E Jolly; Korean J Community Nutr 2023;28(1):61-73. Published online February 28, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.1.61

Objectives
Prophylactic vaccines against high-risk human papillomaviruses (HR-HPVs) hold promise to prevent the development of higher grade cervical intraepithelial neoplasia (CIN 2+) and cervical cancer (CC) that develop due to HR-HPV genotypes that are included in HPV vaccines, but women will continue to develop CIN 2+ and CC due to HR-HPV genotypes that are not included in the quadrivalent HPV vaccine (qHPV) and 9-valent HPV vaccine (9VHPV). Thus, the current vaccines are likely to decrease but not entirely prevent the development of CIN 2+ or CC. The purpose of the study was to determine the prevalence and determinants of CIN 2+ that develop due to HR-HPVs not included in vaccines.
Methods
Study population consisted of 1476 women tested for 37 HPVs and known to be negative for qHPVs (6/11/16/18, group A, n = 811) or 9VHPVs (6/11/16/18/31/33/45/52/58, group B, n = 331), but positive for other HR-HPVs. Regression models were used to determine the association between plasma concentrations of micronutrients, socio-demographic, lifestyle factors and risk of CIN 2+ due to HR-HPVs that are not included in vaccines.
Results
The prevalence of infections with HPV 31, 33, 35 and 58 that contributed to CIN 2+ differed by race. In group A, African American (AA) women and current smokers were more likely to have CIN 2 (OR = 1.76, P = 0.032 and 1.79, P = 0.016, respectively) while in both groups of A and B, those with higher vitamin B12 were less likely to have similar lesions (OR = 0.62, P = 0.036 and 0.45, P = 0.035, respectively).
Conclusions
We identified vitamin B12 status and smoking as independent modifiable factors and ethnicity as a factor that needs attention to reduce the risk of developing CIN 2+ in the post vaccination era. Continuation of tailored screening programs combined with non-vaccine-based approaches are needed to manage the residual risk of developing HPVrelated CIN 2+ and CC in vaccinated women.

Blood Biochemical Characteristics, Dietary Intake, and Risk Factors Related to Poor HbA1c Control in Elderly Korean Diabetes Patients: Comparison between the 4 ^th (2007-2009) and the 7 ^th (2016-2018) Korea National Health and Nutrition Examination Surveys: Sung-Won Oh, Sook-Bae Kim; Korean J Community Nutr 2022;27(5):406-421. Published online October 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.5.406

Abstract PDF

Objectives
The purpose of this study was to investigate the blood biochemical characteristics, comorbidities, dietary intake, and other risk factors leading to poor glycated hemoglobin (HbA1c) control in elderly Korean diabetes patients over 65 years of age.
Methods
Data from the 4 ^th (2007-2009) and the 7 ^th 2016-2018) Korea National Health and Nutrition Examination Surveys (KNHANES) were used. Socio-demographic characteristics (age, gender, region, household income, education level, marital status, nutrition education, diabetes duration and diabetes treatment), lifestyle characteristics (drinking, smoking, regular walking, and subjective health perception), anthropometric characteristics (height, weight, and waist circumference), blood biochemical characteristics (HbA1c, high- density lipoprotein cholesterol, triglycerides, total cholesterol, blood urea nitrogen, and blood creatinine), co-morbidities (obesity, hypertension, hypercholesterolemia, hypertriglyceridemia, and anemia), energy and nutrients intake, food group intake, and HbA1c control-related risk factors were compared.
Results
Compared to the 4 ^th survey, the 7 ^th survey showed an increase in diabetes prevalence among men, an increase in the prevalence of diabetes in the older patients, and an increase in the duration of diabetes. The energy ratio from carbohydrate consumption in the 7 ^th survey was lower than in the 4 ^th .Compared to the 4 ^th survey, thiamine and riboflavin intake had improved, and the intakes of vitamin A, vitamin C, and niacin had worsened in the 7 ^th . A comparison of food group intakes showed that there was a decrease in the consumption of whole grains, potatoes, and milk and an increase in the intake of beverages and alcoholic beverages. The risk factors for poor control of HbA1c were the duration of diabetes and co-morbid hypertriglyceridemia in the 4 ^th survey, whereas subjective health perception, obesity, and hypercholesterolemia as co-morbidities were found to be risk factors in the 7 ^th in addition to the risk factors highlighted in the 4 ^th survey.
Conclusions
For the future management of elderly Korean diabetes patients, greater care is indicated for men over 75 years, and those with low levels of education. It is necessary to increase the intake of milk and vegetables, and reduce the intake of beverages and alcoholic beverages. In addition, it is necessary to reduce the incidence of obesity, hypercholesterolemia, and hypertriglyceridemia for proper control of blood sugar.

Comparison of Nutrient Intake between Hypercholesterolemic and Normal groups based on the 6th Korea National Health and Nutrition Examination Survey: Hyun-A Lee, Hyung-Sook Kim; Korean J Community Nutr 2020;25(5):396-405. Published online October 31, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.5.396

Abstract PDF

Objectives
This study was conducted to compare the nutrient intake of normal healthy adults with those having hypercholesterolemia. Methods We analyzed data from the 6th Korea National Health and Nutrition Examination Survey (KNHANES VI). A total of 12,636 adults (5,223 males and 7,413 females) aged 19 or older were included in the study. Results Males with hypercholesterolemia were older and had a higher waist circumference, body mass index, fasting blood sugar levels (FBS) and serum triglyceride (TG) concentrations compared to the normal group. Females with hypercholesterolemia were older and had higher FBS levels and serum TG concentrations compared to the normal group. While comparing nutrient intake by the 24-hour recall method, the male normal group showed a higher intake of fat, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), vitamin A and thiamin compared to the hypercholesterolemic group. However, the male normal group had a lower intake of iron and vitamin C compared to the hypercholesterolemic group. The female normal group had a higher intake of energy, protein, fat, SFA, MUFA, polyunsaturated fatty acids, cholesterol, riboflavin, and niacin compared to the hypercholesterolemic group, but had a lower intake of iron compared to the hypercholesterolemic group. A comparison of nutrient intake by food frequency questionnaire (FFQ) showed the following: There was no significant difference in nutrient intake between the normal men and women and those with hypercholesterolemia. After adjustment for confounding factors, nutrient intake by FFQ of the male normal group showed higher levels of n-3 fatty acid and vitamin C compared to the group with hypercholesterolemia. However, there was no significant difference in nutrient intake between the two groups of women. Conclusions The average intake of n-3 fatty acids and vitamin C of the male group with hypercholesterolemia was lower than that of the normal group. However, since KNHANES is a cross-sectional study, prospective cohort studies are required to analyze the risk factors of hypercholesterolemia.

Abstract PDF PubReader

OBJECTIVES
This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES).
METHODS
A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects.
RESULTS
As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001).
CONCLUSIONS
These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

Nutritional Status, Quality of Diet and Quality of Life in Postmenopausal Women with Mild Climacteric Symptoms Based on Food Group Intake Patterns: Okhwa Lee, Jinkyung Kim, Hansongyi Lee, Ryowon Choue; Korean J Community Nutr 2012;17(1):69-80. Published online February 29, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.1.69

Abstract PDF PubReader

This study was conducted to examine the nutritional status, quality of diet and quality of life in postmenopausal women with mild climacteric symptoms based on their food group intake patterns. The data for nutritional status were obtained using 3-day records. Quality of diet was assessed by INQ, NAR, MAR, DDS, DVS, DQI-I. Climacteric symptoms were analyzed by the questionnaire of Kupperman's index and MENoL. The subjects were classified into the five groups, GMVDF, GMVdF, GMVDf, GMVdf, GmVDF according to their food group intake patterns. Analysis of nutrient intakes showed that the GMVDF group took significantly higher levels of kcal, carbohydrate, protein, fat, vitamin A, thiamin, riboflavin, folate, vitamin C, vitamin E, calcium, phosphorous, sodium, iron, zinc and fiber than GMVdf group did (p < 0.05). INQ of Ca and Fe appeared to be higher in GMVDF than in GMVdf groups (p < 0.05). Analysis of NARs showed that missing milk groups took lower riboflavin, Ca and P than other groups did as the same result with MAR (p < 0.05). Analysis of DDS and DQI showed that GMVdf group had the lowest quality of diet (p < 0.05); however, no difference was found on DVS. The GMVdf group showed the worst climacteric symptoms compared with those of the other groups (p < 0.05). However, we couldn't observe any differences in menopause-specific quality of life among the groups. In conclusion, it would be beneficial to meet all five food groups to increase the quality of diet and to reduce the climacteric symptoms in postmenopausal women.

Dietary and Lifestyle Factors Associated with Hypertension in Korean Adolescents: Based on 2005 Korean National Health and Nutrition Examination Survey: Killye Kim, Sook Mee Son, Hye Kyeong Kim; Korean J Community Nutr 2011;16(4):439-453. Published online August 31, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.4.439

Abstract PDF PubReader

This study was performed to determine dietary and lifestyle factors associated with hypertension in Korean adolescents. Study subjects were 12~19 years (n = 521) adolescents who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES III). Subjects were divided into the hypertensive group (HG, n = 102) and normotensive group (NG, n = 419) by '2007 Korean children and adolescents growth standard' and the relationships between blood pressure and physical measurement, nutrients intakes, eating behaviors and health related factors were analyzed. HG showed significantly higher levels in weight, waist circumference and BMI than NG. The amount of nutrient intakes was not different between NG and HG. Index of nutritional quality (INQ) for phosphate was higher in HG compared with NG. In both male and female HG, INQ for iron was higher but INQ for vitamin B1 was lower than NG. HG revealed higher consumption frequencies of snack, yoghurt, and ice cream compared with NG. In eating and behavioral factors, 'dinner with family', 'eat proper amount', 'keep Korean traditional diet', alcohol drinking, and mean alcohol intake were significantly different between the two groups. By logistic regression method, risk factors for hypertension revealed in this study were gender (male), age (15~19 years), BMI (> or = 85 percentile), and not keeping Korean traditional diet. These results suggest that education program for hypertension prevention in adolescents should include eating habits improvement and lifestyle modification as well as weight control.

Relationship between Nutrients Intakes, Dietary Quality, and Serum Concentrations of Inflammatory Markers in Metabolic Syndrome Patients: Misung Kim, Juyoung Kim, Wookyung Bae, Sohye Kim, Yesong Lee, Woori Na, Cheongmin Sohn; Korean J Community Nutr 2011;16(1):51-61. Published online February 28, 2011; DOI: https://doi.org/10.5720/KJCN.2011.16.1.51

Abstract PDF PubReader

Elevated serum concentration of inflammation markers is known as an independent risk factor of metabolic syndrome (MS) and dietary intake is an important factor to control MS. The purpose of this study was to investigated the hypothesis that inflammatory indices are associated with dietary intake and diet quality index-international (DQI-I) in subjects with MS. A cross-sectional study was conducted on 156 men and 73 postmenopausal women with MS, defined by three or more risk factors of the modified Adult Treatment Panel III criteria. Serum levels of high sensitive C-reactive protein (hs-CRP), adiponectin were examined and nutrients intake and DQI-I were assessed using a semi-quantitative food frequency questionnaire. The total DQI-I score was significantly higher in female subjects (65.87 +/- 9.86) than in male subjects (62.60 +/- 8.95). There was a positive association between hs-CRP and polyunsaturated fatty acid intake (p < 0.05) and a negative association between adiponectin and lipid (p < 0.05), total sugar (p < 0.01), and total fatty acids (p < 0.05). When the subjects were divided into 5 groups by quintile according to serum adiponectin and hs-CRP level, there was no association between DQI-I score and hs-CRP levels. Moderation score of DQI-I was significantly higher in highest quintile group than the lower quintile groups. Therefore, our results provide some evidence that dietary intake and diet quality are associated with inflammation markers and dietary modification might be a predictor to decrease risk for metabolic syndrome complications. However further research is needed to develop the dietary quality index reflecting the inflammatory change by considering the dietary habit and pattern of Koreans.

Comparison of the Dietary Factors between Normal and Constipation Groups by Self-reported Constipation in Female College Students: Chae Rin Lee, Soon Kyung Kim; Korean J Community Nutr 2011;16(1):23-36. Published online February 28, 2011; DOI: https://doi.org/10.5720/kjcn.2011.16.1.23

Abstract PDF PubReader

The purpose of this study was to obtain baseline data on dietary management of women's constipation. We estimated the prevalence of self reported constipation, bowel habits and foods & nutrients intake. The subjects were 169 female college students (normal = 92, constipation group = 77) aged 19 to 23 years. We conducted anthropometric measurements, an evacuation habits survey, and a dietary intake assessment for three days by a 24 hour recall method. The prevalence of self reported constipation was 46% (n = 77). Results showed that bowel habits (the difficulty of evacuation, the duration of evacuation and the feeling after evacuation) were significantly different between the two groups. Over 65% of constipation group used laxatives for constipation relief. Frequency of stress and deep sleeping were related with constipation. In daily food consumption and nutrients intake, there was not a significant difference between the groups. However in relation to bowel habits which factors influence constipation, the study showed that the intake of water, potatoes, kimchi, and fruits correlated with evacuation facility. Further, there were no findings in the difference of foods consumption and nutrients intake between the two groups. But some life style changes and food intakes (potato and kimchi) may be useful to improve constipation symptoms in young women.

Effects of Frequent Eating-out and Breakfast Skipping on Body Mass Index and Nutrients Intake of Working Male Adults: Analysis of 2001 Korea National Health and Nutrition Survey Data: Joung Won Lee; Korean J Community Nutr 2009;14(6):789-797. Published online December 31, 2009

Abstract PDF: In order to investigate the effects of frequent eating-out and breakfast skipping of working men on body mass index and nutrients intake status, working male adults aged 20 or over were selected (n = 1883) from the data of 2001 Korea national health and nutrition survey. The subjects were divided into 4 groups according to the eating-out frequency(high: once or more daily, low: less than once daily) and breakfast eating or not. Four groups were high eating-out with breakfast eating (n = 609), high eating-out with breakfast skipping (n = 192), low eating-out with breakfast eating (n = 877), and low eatingout with breakfast skipping (n = 205). High eating-out group showed higher body mass index (BMI) than low eating-out group, but the difference of BMI was disappeared when adjusted with age, residence region and family income. However high eating-out group in case of breakfast eating, compared with the low eating-out, showed higher intakes or densities of energy, fat, fat-energy% and higher ratio of energy-fat overintake, and also showed higher mean nutritional adequacy ratio and lower ratio of nutrients intake deficiency. Calcium, iron, vitamin A and C intakes were not affected by eating-out frequency, but were lowered by breakfast skipping. Breakfast skipping also decreased intake frequency of unprocessed cereals and increased those of ramyon and carbonated and alcoholic beverages. From the results frequent eating-out with breakfast eating caused increased intakes of energy and fat, but did not cause BMI increase. Breakfast skipping, but not eating-out, had negative influences on mineral and vitamin intakes. Accordingly good eating-out as well as breakfast eating should be exceedingly emphasized at nutrition education for the working males.

Association of Nutritional Status with Obesity by Body Mass Index and Waist Circumference among Hypertensive Elderly Patients: Kyung Hee Seo, Hye Jin Lee, Bu Dol Lim, Yun Jung Choi, Hyunmee Oh, Jin Sook Yoon; Korean J Community Nutr 2009;14(6):831-845. Published online December 31, 2009

Abstract PDF: Hypertension and obesity are important modifiable risk factors for cardiovascular disease, the leading cause of death in Korea. Therefore, we assessed the association between dietary pattern and obesity in hypertensive patients to formulate health promotion strategies for the older population. Dietary information was collected from hypertensive patients visiting community health education and information center by using 24 hour recall method. The 2005 DRIs for Koreans was used to evaluate the dietary adequacy. When subjects were categorized by body mass index (BMI) as normal, overweight and obese, no significant difference in energy intake was found among groups. Dietary intakes of folate, and vitamin C in obese hypertensive patients were significantly lower than in normal weight patients (p < 0.05). When we compare the nutritional status by waist circumferences, dietary intakes of zinc, vitamin A, thiamin, vitamin C and folate were significantly lower in the obese group. Vegetable intake was significantly lower in the obese group according to BMI as well as waist circumference. Energy intake from carbohydrate was significantly higher in obese hypertensive patients (p < 0.05). Obese hypertensive patients had a higher risk of nutritional inadequacy compared to normal weight patients. Our results indicated the need for developing interventions that encourage greater consumption of vegetables while cutting down salt intake with wise selection of staple foods, for obese hypertensive patients.

Effects of Body Composition and Nutrients Intake on the Calcaneal Broadband Ultrasound Attenuation in College Students: Eun Joo Jea, Kwang Eui Byoun, Jung Eun Youn, Byung Kook Lee, Hee Seon Kim; Korean J Community Nutr 2009;14(5):590-599. Published online October 31, 2009

Abstract PDF: The purpose of this study was to analyze the relationship of nutritional status measured by the body composition and dietary nutrients intakes with calcaneal broadband ultrasound attenuation in college students. Total of 886 (462 male and 424 female) students who received health examination in May 2007 participated in this research.Participants bone status was measured by a quantitative ultrasound method and t-score was calculated via WHO guideline. For body composition measurements, body fat, height and weight were measured and BMI was calculated. Dietary data were collected by a 24-hour recall method. Based on Asia-Pacific standard of WHO, BMI was divided into 3 groups; UW (BMI<18.5), NW + OW (18.5< or =BMI<25) and Obese group (25< or =BMI). Among male students, 2.4% belong to the UW group, 45.0% to the NW+OW group and 52.6% belong to the obese group, while 10.4% of female students belong to the UW group, 71.9% to the NW + OW group and 17.7% of female students belong to the Obese group. Differences among male and female students were statistically significant (p<0.001). Students with higher BMI showed significantly higher bone health status. Male students did not show any significant differences in nutrients intakes by BMI groups while female students showed the higher intakes of energy, protein, pyridoxin, phosphorus, iron and zinc among NW + OW group than other groups (p < 0.05). The qualitative and quantitative evaluation of diet by BMI groups did not show any significant differences in both male and female students. The result of the multiple regression analyses showed that the body fat and bone status was negatively related while energy intake was positively related with the bone status. These results revealed that bone health status was positively affected by BMI but not by body fat. In conclusion, among those who are at their twenties, the period when the bone density becomes maximized, body fat may negatively affect bone health unlike during other life cycle stages.

Abstract PDF: Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and > or = 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 +/-8.0 yr) was significantly higher than that of > or = 25 months group (62.2 +/- 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in <25 months group and the amounts of alcohol consumption were significantly higher in > or = 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

Abstract PDF: The purpose of this study was to provide a descriptive assessment of the nutritional habits of resistance trained males in relation to protein and carbohydrate intakes in comparison with the recommended values. Thirty-four male bodybuilders (27.0 +/- 2.1years, 173.5 +/- 5.0 cm, 8.3 +/- 0.61% body fat), twenty-four male weight lifters (20.9 +/- 2.1years, 171.8 +/- 6.9 cm, 7.6 +/- 0.98% body fat) and twenty-five male non-athletes (26.9 +/- 2.5years, 175.3 +/- 5.7 cm,, 8.5 +/- 0.95% body fat) participated in the study. Participants completed a comprehensive survey by twenty-four hour dietary recall methods. All diets were analyzed using the Computer Aided Nutritional (Pro) analyzer by a registered dietician. Body fat was measured using skin fold thickness. The average time spent in resistance training was 18.0 +/- 1.7 hrs/week for body builders and 14.6 +/- 8.7 hrs/week for weight lifters. Total daily calories were 2583.6 +/- 874.8 kcal (31.9 +/- 11.9 kcal/ kg) for bodybuilders, 3565.9 +/- 1281.8 kcal (42.7 +/- 15.0 kcal/kg) for weight lifters and 2016.0 +/- 955.3 kcal (28.1 +/- 13.9 kcal/kg) for non-athletes (p = 0.001). Percent of calories from carbohydrate, protein, and fat 64.2%, 27.1%, and 8.7% for bodybuilders, and 66.3%, 18.6%, and 15.1% for weight lifters. The mean protein intake was 1.9 +/- 1.2 g/ kg of BW for bodybuilders, 1.6 +/- 0.6 g/kg of BW for male weight lifters and 1.1 +/- 0.69 g/kg of BW for non-athletes. Although dietary calcium (78.7%) and riboflavin (86.3%) intakes for bodybuilders were below the RDA, dietary intakes of micronutrients were not deficient. More research needs to be conducted to determine the optimal amounts of protein, carbohydrates, fats, and micronutrients for the resistance trained athletes.

Abstract PDF: The purpose of this study was to investigate the dietary habits and daily intake of nutrients in college students. This survey was conducted using a self-administered questionaire. The average heights and weights were 173.5 cm and 72.3 kg of male students and 161.8 cm and 57.2 kg of female students. The average of BMI was 24.2 kg/m2 of male and 21.9 kg/m2 of female, and the value of male students was higher than the value of female students. The response to the daily meals was 54.6% for '2~3 times/week'. The regularity of mealtime was 41.7% for irregular and the frequency eating after nine was 45.7% for '5-6 times/week', respectively. The repast was 72.2% for 'overeating and little eating' and was a significant difference of male and female students (p < 0.05). The eating rate was higher '10 ~20 min'. As for breakfast food eaten, skipping breakfast was 23.6% for 'no/week' and female students were higher than male students (p < 0.05). The frequency of snacks was 36.0% for 'nothing' of males students and 34.8% for '3- 4 times/week' of female students (p < 0.05). The type of snack was a significant difference of males and females students (p < 0.01), and was the highest 75.0% for carbonated drinks of males and 37.5% for snacks of females. The eating due to stress solution was a significant difference of male and female students (p < 0.01), and was the highest 23.0% for 'frequency' of males and 44.7% for 'sometime' of females. As for food intake of male and female students, the meat intake was 66.7% for 'everything of male and female students. The fish intake was 68.1% for '1- 2times/week'. The milk, milk products, eggs and beans were each 40.3%, 58.3%, 56.9%, 47.2% for '1-2 times/week' (p < 0.05). The fat intake was 55.6% for '1~2 times/week'. The average consumption of energy was 58% of male and 67% of female of estimated energy requirement (EER). Their mean ratio of carbohydrate : protein : fat was 57 : 15 : 28 of all subjects. The mean intakes of vitamin C and folic acid were 70% and 51% of males and 62% and 52% of females of recommended intake (RI). The mean intakes of Ca, P, Fe and Na were 71%, 140%, 146% of males and 72%, 122%, 76% of female of RI and 273% of males and 233% of females of adequate intake (AI).

The Analysis of the Dietary Factors Related to Climacteric Symptoms in Middle-aged Women: Soon Kyung Kim, Jae Gun Sunwoo; Korean J Community Nutr 2007;12(1):25-39. Published online February 28, 2007

Abstract PDF: The purpose of this study was to investigate the dietary intakes in middle-aged women (pre and postmenopausal) and relation to climacteric symptoms. We conducted the anthropometric measurements, climacteric symptoms survey, and dietary intake to assess the nutrient intakes. Also, dietary quality indices were evaluated. The subjects, over 40 years old, were 168 middle aged women ( pre = 74, postmenopausal = 94), mean age was 48.9 +/- 3.6yr. The anthropometric measurements showed that 59% of subjects were overweight and obese. Climacteric symptoms that were answered "yes" in 50% plus in the subjects, were dry eyes, forgetfulness, difficult concentration, large joint pain (shoulder), fatique, backache, dry skin, joint pain (ankle and knee), dry mouth, dizziness, depression and lonesomeness, snore, morning stiffness, and hot flash. Some symptoms showed significant difference between pre and postmenopausal groups. The average energy intake was 1602.1 Kcal, which was 82% of the Korean EER. The subjects had lower vitamin A, riboflavin, folic acid, Fe, Zn and Ca intake than Korean RI. The lowest nutrient intake was Ca. The mean of food intake was 1294.2 g and MAR of diet quality indices was 0.83. In relation to dietary factors with climacteric symptoms, significant correlations have been found between total protein, animal protein, lipid, cholesterol and niacin intake and "fatique", energy, carbohydrate, thiamin, vitamin B6, folic acid, vitamin C, Na, K and Fe intake and "dry skin", Ca intake and "difficult concentration". Our results indicate that dietary factors (food and nutrients intake, INQ, NAR, MAR) may effect the prevention and reduction of some climacteric symptoms in middle aged women.

Dietary Macronutrients and VO2 by BMI among Female College Students in Seoul: Jae Yeon Lim, Hae Bok Na; Korean J Community Nutr 2006;11(1):52-62. Published online February 28, 2006

Abstract PDF: This study was conducted to investigate dietary macronutrient and VO2 by BMI. The subjects consisted of 50 female college students. They were divided into three groups: Below BMI 18.5 kg/m2 (n = 9), BMI 18.5 - 23 kg/m2 (n = 28), above BMI 23 g/m2 (n = 13). Health-related questionnaires, dietary macronutrients, macronutrient compositions, food frequency questionnaires, body compositions and VO2 were studied. Macronutrient compositions that macronutrient intakes were expressed by the percentage of daily energy intakes. There were significant differences in body fat, percent of body fat, and fat distribution by BMI. Also, significantly increasing of basal metabolic rate (BMR) was shown by BMI, but BMR per body weight was decreased by BMI. Overall, there were no significant differences in health-related questionnaires, food frequency questionnaires (FFQ), dietary macronutrients and VO2 by BMI but salty taste preferences and carbohydrate intakes, FFQ of beans, white vegetables rand, yellow-green vegetables in the above BMI 23 g/m2 group were significantly higher than other groups. There were no significant differences in macronutrient composition but the lipid composition of subjects was shown above 20%. Also, energy intakes of subjects were shown to be low; especially the below BMI 18.5 kg/m2 group was very low (55% of RDA). Significantly positive correlation was found in BMR and body composition such as skeletal muscle & lean body mass, but significant correlation was not found in BMR and dietary macronutrients. Overall, researched energy metabolism factor was not different by BMI. Only in the BMI 18.5 - 23 kg/m2 (normal) group, significantly positive correlation was found in VO2peak and body fat oxidation. Therefore, proper nutritional education for female college students is needed in order to improve their obesity-related health. Moreover, a nutritional survey method of finding diverse factors that affect their health should be developed to meet various needs.

Dietary Behaviors and Status of Nutrient Intakes by the Obesity Levels of Housewives in Daegu: Jung A Park, Jin Sook Yoon; Korean J Community Nutr 2005;10(5):623-632. Published online October 31, 2005

Abstract PDF: This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of healthy weights at community level. Nutrient intakes of 128 housewives were assessed by 24 hour recall method. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Subjects were divided to under-weight, normal-weight, over-weight groups by body mass index (BMI). Most under-weight groups evaluated as their current body images were normal. 41% of normal-weight groups judged as their current body images were obese. Energy and fat intakes of over-weight group were significantly higher than that of under-weight and normal weight groups (p < 0.05). However, carbohydrate and protein intakes showed no significant differences among the three groups. It appeared that active attitude toward change in nutrition attitude of normalweight group was significantly higher than that of under-weight group (p < 0.05). There were no significant differences of food habit score, nutrition knowledge, and obesity habit scores among the three groups. The frequency of eating-out showed significant difference among three groups (p < 0.05). Food habit scores were positively related to health-concerned attitude (r = 0.174), convenience-concerned attitude (r = 0.229) and food enjoyed attitude (0.213) and negatively related to obesity habit score (r = -0.206). Also, positive correlation of body fat mass with frequency of eatingout (r = 0.213), instant food (r = 0.227) and amount of meal (r = 0.187) existed (p < 0.05). We concluded that nutrition education programs for housewives should include specific strategies to modify unsound food behaviors and inappropriate perception of body image for a healthy weight.

A Study on Nutrient Intake, Anthropometric Data and Serum Profiles among High School Students Residing in Seoul: Hyun Sook Lee, Bo Eun Kim, Mi Sook Cho, Wha Young Kim; Korean J Community Nutr 2004;9(5):589-596. Published online October 31, 2004

Abstract PDF: This study was performed to investigate the anthropometric data, serum profiles, and nutrient intakes of high school students who are living in Seoul. Anthropometric data showed that mean height and weight were 174.1 cm and 66.6 kg in 99 male and 161.4 cm and 54.0 kg in 116 female students. Mean BMI for male and female students were 21.9 and 22.3 kg/m2, and subjects with BMI > 25 kg/m2 were 14 and 7%, respectively. Total cholesterol, HDL- and LDL-cholesterol of subjects were 149.6 +/- 3.1, 46.4 +/- 1.3, 86.4 +/- 2.3 mg/dl for males and 169.2 +/- 3.1, 50.7 +/- 1.0, 100.9 +/- 2.7 mg/dl for females, respectively. Hemoglobin (Hb) and total iron binding capacity (TIBC) were 12.8 +/- 0.1 g/dl, 437.3 +/- 7.2 microgram/dl in male and 11.9 +/- 0.1 g/dl, 439.4 +/- 5.7 microgram/dl in female, respectively. Based on Hb classification, 45.6% of male and 45.0% of female students fell into anemic condition. Intakes of energy, Ca, Fe, Zn, riboflavin, and folate were below the Korean RDA. In particular Ca (male and female, respectively, 64.6 and 643% RDA) and Fe (male and female, respectively, 78.6 and 64.3%RDA) intakes were extremely low. Serum triglyceride was positively significantly correlated with weight (r = 0.22), BMI (r = 0.279), waist circumference (WC, r = 0.235), triceps skin-fold thickness (TSF, r = 0.197) and obesity index (OI, r = 0.279). Hb concentration was positively correlated with height (r + 0.387), weight (r = 0.349), BMI (r = 0.191) and waist/hip ratio (WHR, r = 0.380). As for the correlation between serum profiles and nutrient intakes, the Hb concentration was positively correlated with energy (r = 0.163), protein (r = 0.149), Na (r = 0.153), vitamin A (r = 0.165), thiamin (r = 0.201) and niacin (r = 0.192, p < 0.01). These result suggest that the prevalence of Ca and Fe deficiency of student is high and dietary guideline for prevent anemia in this age needs to contain the adequate intake of energy and its related vitamins.

The Dietary Behaviors, Depression Rates and Nutrient Intakes of the Elderly Females Living Alone: Jin Kyung Park, Sook Mee Son; Korean J Community Nutr 2003;8(5):716-725. Published online October 31, 2003

Abstract PDF: In this study, the dietary behaviors, depression rates and nutrient intakes were assessed for elderly females living alone (ELA) and elderly females not living alone (ENLA). The subjects were 140 elderly females (living alone 70; not living alone 70) residing in Bucheon city. Dietary data were obtained using the 24-hr recall method. There were more subjects with low monthly incomes (less than 500,000 won) in the ELA group. The proportion of the ELA group which skipped at least one meal per day was 38.5% and the main reasons given were low appetite and depression. Fewer of the ELA group were observed to have smoking and drinking habits. However, the majority of the ELA smokers smoked more than 6 cigarettes per smoking. The drinking score of the ELA group was also higher than that of the ENLA group. The total score of depression for the ELA group was higher than that of the ENLA group. The total score of nutrition risk index (NRI) of the ELA group (8.09) was also higher than that of the ENLA group (2.31). The dietary assessment using the 24 hr-recall method showed that the ELA group had lower nutrients intakes, and significant differences were shown in the intakes of energy (1137 kcal vs 1275 kcal), animal protein, animal fat, carbohydrates, animal Ca, and animal Fe. There was a positive correlation between the NRI and the depression scores. However a higher NRI was associated with lower intakes for most of the nutrients in the ELA group.

The collected data were consisted of items on general characteristics, dietary behavior, nutrition knowledge and daily nutrient intakes of subjects. The subjects were classified into obese and non-obese control groups according to their relative weights. Frequency of skipping breakfast and eating rate of obese group were significantly higher than those of control group. There was no significant difference between obese and control group in the nutrition knowledge score. Except vitamins B1, B2 and iron, the average daily intakes of other nutrients in obese were greater than control group. The most contributing factor to BMI turned out to be cholesterol intake. After the nutrition education targeting obese children, their nutrition knowledge scores improved, but the dietary behavior score was not significantly changed. Therefore, childhood obesity may be prevented by continuous education programs including the behavior modification of obese children.

Nutritional Evaluation, Stability of Cereals and Sanitation Status of Processing Utensils and Environments Based on Hygiene Education: Eun Mi Kim, Hyun Sook Kim; Korean J Community Nutr 2002;7(6):833-843. Published online December 31, 2002

Abstract PDF: This study was carried out to investigate the effect of hygiene education on the microbiological changes of processing utensils and the environmental in the manufacture of cereals and to evaluate the Cd, Pb contents and nutrient compositions of 11 cereals. The result of microbiological evaluation was that fungi, coliforms and staphylococcus species were detected in employees, on equipment, utensils and environments in the first inspection. Fungi were detected in most of the cereals, staphylococcus species were detected in soybeans, perilla seeds and sea tangle flour, and bacillus cereus was detected in sorghum and black sesame seeds. The water content of rice, barley, glutinous rice, brown rice and carrot flour in packaged products, and in carrot flour, angelica keiskei, carrot, sea mustard and potato in bulk products was in excess of 8.0%. The Pb content of cereals was 0.14 - 0.51 mg/kg and Cd was not found. The acid value of Job's tears flour and black sesame seed flour was higher than 5.0 mg/g oil. Cereals were manufactured from 41 different cereals and grains, legumes, seeds and nuts, vegetables, potatoes, seaweeds, fruits, glucose and salt. The average content of cereals and grains, legumes, and seeds and nuts in cereals was 75.75%, 16.19% and 4.93%, respectively. The mean nutrient content per 100 g of cereals was calories 365.8kcal, protein 13.3 g, fats 5.9 g, carbohydrates 63.4 g, Ca 91.8 mg, P 269.9 mg, Fe 3.15 mg, Na 76.2 g, K 421.8 mg, Zn 2.33 mg, Vit. A 12.5 R.E., Vit. B1 0.23 mg, Vit. B2 0.16 mg, Vit. B6 0.46 mg, Niacin 3.5 mg, Vit. C 1.36 mg, folic acid 62.3 microgram and Vit. E 1.24 mg. When nutrients value of 48 g of cereals and 200 ml of milk was compared to 1/3 of the RDA, the values were below than 60% of 1/3 of the RDA except Na, K, Vitamin B1 and C contents. The average carbohydrate : protein : fat ratio of energy intake was 54.27 : 17.45 : 28.28, respectively. Therefore, a training program consisting of the education of the staff in surveillance and standard operating procedures, the elimination of dangerous procedures, sanitation checklist, the implementation of preparation methods and standard recipes for cereals is required.

Nutrients Intake, Zinc Status and Health Risk Factors in Elderly Korean Women as Evaluated by the Nutrition Screening Inistiative (NSI) Checklist: Jin Sook Yoon, Junghyun Lee; Korean J Community Nutr 2002;7(4):539-547. Published online August 31, 2002

Abstract PDF: The purpose of this study was to investigate whether the health status as determined by a self-assessment checklist was related to the nutritional status of elderly Korean women. We interviewed 59 female subjects living in the Daegu area aged over 55 years. Information on their dietary intake on two consecutive days was collected by the 24-hour Recall Method. Their body compositions were measured using a Bio-electrical Impedence Fatness Analyzer. Their zinc status was evaluated according to their dietary zinc intake and urinary zinc excretion in urine samples collected for 24 hours. Their heath status was determined by a NSI Checklist. While 50.9% of the total subjects belonged to a moderate nutritional risk group, 23.7% of the subjects were at a high nutritional risk. It appeared that only 25.4% of the subjects were evaluated as being healthy. Therefore, the overall nutritional health status of the elderly females belonged to the moderate nutritional risk group. Except for vitamin C, the average daily nutrient intake of the subjects was below the level of the recommended dietary allowances (RDA) for Koreans. The lower the nutritional health score, the better was their dietary intake of energy (p < .05), protein (p < .001), and zinc (p < .01). A positive relationship between their nutritional health score and body fat ratio was also observed (p < .05). Therefore, we suggest that the NSI Checklist could be used as a practical screening tool at the beginning of nutritional surveillance of the elderly in the community.

Food Habits, Nutrients Intake, and Disease Distribution according to Sasang Constitutions in the Elderly Aged over 65 Years(II): Youn Kyoung Kim, Mi Ran Cho, Rin Chang, Ryo Won Choue; Korean J Community Nutr 2002;7(1):76-85. Published online February 28, 2002

Abstract PDF: Since the 1970s, the average life expectancy of Koreans has been increasing. Our concerns are not simply about longevity, but also about disability-free life. lately, Sasang constitutional medicine has attracted public attention, especially with respect to the elderly. The purpose of this study was to investigate the food habits, nutrients intake, and disease distribution among the elderly, according to their Sasang constitutions. The results are as follow : The distribution of constitutions of the subjects were Tae-eum 48.8%, So-yang 27.4%, So-eum 22.6%, and So-yang + So-eum 1.2%. In both elderly men and women, body weight, percent ideal body weight, and diastolic pressure of the Tae-eum were significantly higher than those of other constitutions. In both men and women, the level of hemoglobin in the Tae-eum was significantly higher than those of other constitutions. The level of LDL-cholesterol was higher, and the level of HDL-cholesterol was lower in the So-eum elderly women. Food habits of the So-eum were the most irregular, and nutrients intake of the So-eum was lower than that of other constitutions in both elderly men and women. In elderly men, the incidence of hypertension was the highest in the Tae-eum, and the incidence of gastritis was the highest in both So-yang and So-eum. In elderly women, the incidence of fatty liver was the highest in the Tae-eum and So-yang, and gastritis and hypertension were the highest in the So-eum. In the elderly, obese and anemic persons were significantly more in the Tae-eum and the So-eum, respectively. The results of this study showed that there were significant differences of physical, characeristics, food, habits, and distributions of disease for the subjects according to each Sasang constitutions. Intake of nutrient was poor, regardless of Sasang constitutions, in both men and women.

Abstract PDF: The purpose of this study was to investigate the association among food intake frequency, nutrient intake, anthropometric measurements, and serum lipids in 100 women and 85 men aged 40-74yrs residing in Jeonju City. Food intake frequency and nutrient intake were obtained from one-day dietary recalls. The results were as follows : The mean height, body weight and BMI were 161 cm, 62.5 kg, and 24 kg/m2 respectively. The mean of SBP and DBP were 118 mmHg, 77 mmHg respectively. The mean of TC and TG were 185.5 mg/dl, 153 mg/dl respectively. The mean daily energy and carbohydrate intake was 85. 7%, 91% of RDA for Koreans respectively and that protein intake was 118.5% of RDA. The TC levels of subjects less than 75%, 75-125%, more than 125% of RDA energy were 176 mg/dl, 192 mg/dl, 185 mg/dl respectively(p<0.01). The TC levels less than 75%, 75-125%, more than 125% of RDA protein were 180 mg/dl, 190 mg/dl, 175 mg/dl respectively(p<0.05). TC levels less than 75%, 75-125%, more than 125% of RDA fat were 181 mg/dl, 193 mg/dl, 194 mg/dl respectively(p<0.05). Of the subjects, 18% ate mushrooms. The BMI of the mushroom eaten was 24 and that of non-mushroom eaten was 25(p<0.05). Of the subjects, 28% consumed milk and milk produce. The mean level of TC and TG in milk and milk products eaters were 181 mg/dl, 131 mg/dl and that of non milk and milk products eaters were 197 mg/dl, 159 mg/dl(p<0.001, p<0.05). Of the subjects, 58% ate fish. The HDL-C of the fish eaten was 50 mg/dl and that of non-fishes eaten was 45 mg/dl(p<0.05).

An Assessment of Obesity and Dietary Habits of College Students Taking the Course Health and Diet: Hyeon A Kim, Kyung Hwa Lee, Young Ja Cho; Korean J Community Nutr 1999;4(2):166-174. Published online June 30, 1999

Abstract PDF: We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of theirnutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, 21.5kg/m2 and -1.2% in male students and 27.3%, 21.2kg/m2 and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in underweight students than in students of normal and over-weight. Female students were found to skip mealsand consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eate as well as the frequency of eating salty foods. These results suggest that in order to assess obesity propertly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.

Within-and between-person Variation in Nutrient Intakes by the Korean Elderly: Myung Hee Hong, Se Young Oh; Korean J Community Nutr 1998;3(3):423-429. Published online August 31, 1998

Abstract PDF: This study examined within- and between-person variation in nutrient intakes in order to estimate the degree of precision in dietary assessment among 37 males and 46 females whose mean age was 70.4 years old. To collect dietary data, each subject was interviewed 5 or 6 times using a 24-hour recall method during a 3 month period. Within-person variation ranged from 23.5% to 101.2%. Lower values of within-person variation were observed in energy, carbohydrated, protein and phosphorous while higher value was observed in vitamin A. Between person variations of nutrient intakes ranged 12.6-23.5% in most nutrients. With 1 day dietary data, observed nutrient intakes were estimated to within 6-25% of the group's usual9true) intakes and 52-198% of the individuals' usual intakes. The values of these maximum percentage deviations became smaller when the number of dietary recalls increased. The results of this study suggest that the Korean elderly subjects appear to have a slightly less diverse diet compared to young Korean women. Within persons, intakes of nutrients largely from animal sources were more variable for the Korean elderly than for their counterparts in Western countries. This study also implies that commonly used 1 day dietary study may be appropriate for assessing group means of nutrient intakes, but clearly not appropriate for assessing individual's nutrient intakes.
