Cross-sectional Study of Growth of Korean Breast Fed Formula Fed Infants from 1 to 3 Postpartum Months: Kyungsuk Choi, Haymie Choi, Sang Jin Chung, Jaeok Koo, Hyeon Sook Lim; Korean J Community Nutr 1997;2(1):3-12. Published online February 28, 1997

Abstract PDF: One-to three -month-old infants(n=252) were compared their growth performance(weight, length, head circumference, chest circumference) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). The weights of infants at 1, 2, and 3 postpartum month were 4.50+/-.48kg, 5.76+/-0.62kg and 6.67+/-0.68kg, respectively. The weigh of male infants was higher than females. The length were 53.7+/-2.6cm, 57.4+/-3.3cm, 61.1+/-3.1cm at one to three postpartum months, respectively. The length of male infants was higher than females, too. Overall there were no significant differences between feeding methods in weight, length, head and chest circumferences, and monthly weight and length velocity. But 3-month-old formula-fed male infants showed bigger significantly in weight, monthly weight velocity and chest circumference than the breast-feds. By Korean standards, weight-for-height Z-score were distributed from 0 to +2. Not only was there a few malnourished infants but also overnourished were noticed, especially in formula-fed group.

A Study on Prevalence of Obesity, Eating Habits and Life Styles of 5th Grade Students in Inchon: Jeong Soon You, Yun Jin Choi, in Suk Kim, Kyung Ja Chang, Hee Chyun; Korean J Community Nutr 1997;2(1):13-22. Published online February 28, 1997

Abstract PDF: The purpose of this survey was to investigate the prevalence of obesity, eating habits and life styles of children. This survey was carried out anthropometry and questionnaires in 180 male and 141 female students of fifth-grade at Dongmak elementary school. The results are summarized as follows : 1)18.2% of the male and 19.3% of female students were obese. Underweight group was 10.5% of the male and 15.0% of the female students. 2) Average height of male and female students were 142.0 cm, 144.0 cm and weight of those were 35.8 kg and 37.1 kg respectively. The height and skinfold thickness of the triceps in female students were significantly higher than those of male students and body fat content in female students was significantly lower than that of male students. There was no difference in BMI, RW and RI between male and female students. The average BMI, RW, RI were 17.7, 25.4, 124.0, respectively. 3) The student's height was positively related to parent's height and moth's weight. There were significantly positive correlation between mother's and subject's weight. BMI, RW and RI were positively related to parent's BMI. 4) 78.3% of male and 51.8% of female students had prejudice for special food, and 45.5% of male and 34.5% of female students had an overeating habit. Male students had significanthy higher rate than female in both cases. Average eating time per meal was 18.9 minutes for male and 21.0 minutes for female students. Experience for taking nutrient supplement in male student was more than that in female. Obese group had prejudice for special food, overeating habit and rapid eating rate more than any other groups. The prevalence of obesity among the children is gradually increasing. Therefore, in order to prevent progress into adulthood obesity, nutrition education including the right perception for obesity and eating behavior modification was needed.

Iron Nutritional Status of Female Students in Kangnung National University: Kyukee Lee, Eunkyung Kim, Mikyung Kim; Korean J Community Nutr 1997;2(1):23-32. Published online February 28, 1997

Abstract PDF: To evaluate iron nutritional status of female college students, fasting blood samples were taken from 76 female students of Kangnung National University. Hemoglobin(Hb), hematocrit(Hct), serum iron(Fe), total iron binding capacity(TIBC) and serum ferritin concentrations were measured and transferrin saturation was calculated. Mean values for Hb, Hct, Fe, TIBC, TS and serum freeitin were 13.64+/-1.42g/dl, 40.99+/-4.31%, 103.0+/-33.3 microgram/dl, 395.3+/-9.07 microgram/dl, 26.58+/-9.07%and 26.76+/-17.5ng/ml, respectively. Prevalence of iron deficiency greatly varied by indices from 6.8% when judged by Hct to 26.0% by serum ferritin concentration. The Hb concentration was positively correlated with hematocrit (r=0.5402), serum iron(r=0.2819) and transferrin saturation(r=0.2777)(p<0.05). on the other hand, serum ferritin concentration showed significantly negative correlation with TIBC(r=-0.3196). Two-day dietary intake records were collected from subjects to estimate mean daily iron intake and bioavailability of dietary iron. Mean daily intake of iron was 13.15 mg and heme iron intake was 0.83 mg which was 6.4% of total iron intake. Total absorbable iron calculated by the method of Monsen was 1.27 mg and bioavailability of dietary iron was 9.6%. In the light of high prevalence of iron deficiency based of serum ferritin concentration and low bioavailability of iron in the diet, guidelines about diet should be made to increase the content and bioavailability of iron in the diet if female college students.

A Study on Dietary Intakes and Nutritional Status in College Women Smokers - I. Anthropometric Measurements and Nutrient Intakes: Jung Hee Kim, Hwa Shin Lee, Jeong Suk Moon, Kyungwon Kim; Korean J Community Nutr 1997;2(1):33-43. Published online February 28, 1997

Abstract PDF: In order to investigate the dietary intakes and physical characteristics in college women smokers, interviews using questionnaires were done on 33 smokers and 42 nonsmokers residing in seoul area. General living habits, dietary habits, food consumption frequency and nutrient intake by quick estimation were investigated through direct interviews with subjects. Subjects height, weight and blood pressure were measured, and body fat percentage were statistically analyzed using Bio-electrical Impedence Fatness Analyzer(GIF-891). All data were statistically analyzed by SAS PC package program ; percentage or mean and standard error were examined for each item, and the significant difference was evaluated by chi-square test or Student's t-test at alpha=0.05. In the analysis of taste and food preference, smokers consumed larger amount of alcohol and coffee than nonsmokers ; they also disliked sweet taste. The results of food consumption frequency data also showed that smokers consumed less fish, milk and fruits but consumed more instant foods than nonsmokers. As a result of anthropometric measurements, height, age, and body fat percentage showed no difference, but there was a significant difference in weight, BMI, systolic blood pressure, and diastolic blood pressure. Energy intake in nonsmokers was 1640 kcal/day(CHO : Pro : Fat=66.0 : 14.7 : 19.3), in smokers. Intakes of calcium, iron, vitamin C, vitamin A, vitamin B1, vitamin B2, and niacin in smokers were not significantly different from those of nonsmokers.

Relation of Serum Vitamin E and Lipoperoxide Levels with Serum Lipid Status in Korean Men: Sung Hee Cho, Young Sun Choi; Korean J Community Nutr 1997;2(1):44-51. Published online February 28, 1997

Abstract PDF: Secrum lipid and vitamin E levels were determined and smoking, alcohol drinking and exercise habits were asked in 357 healthy male subjects aged 49.4+/-6.7 years in Taegu. Average serum levels of total cholesterol, HDL-cholesterol and triglyceride(TG) were 189+/-43 mg/dl, 42+/-13 mg/dl and 136+/-73 mg/dl, respectively. Serum level of lipid peroxide measured as thiobarbituric acid reactive substances(TBARS) of the subjects was 2.01+/-0.73MDA nmoles/ml and that of alpha-tocopherol was 9.53+/-3.14ug/ml. The correlation coefficients between alpha-tocopherol and serum lipids were 0.3631 for triglyceride, 0.2993 for cholesterol, and 0.3025 for total lipid. Heavy smokers who smoked more than 20 cigarettes a day had higher levels of TG and TBARS than those who smoke less. Alcohol drinkers had higher levels of TG and TBARS than nondrinkers. Vitamin E level(per ml serum)was significantly higher in the heavy smokers and drinkers, which was reflected by the higher level of serum lipid. When the level of alpha-tocopherol was expressed as alpha-tocopherol/triglyceride, it was negatively correlated with serum TBARS level and was lower in the heavy smokers than in the moderate smokers. It is concluded that vitamin E level as alpha-tocopherol/triglyceride would be better compared to alpha-tocopherol/total cholesterol or alpha-tocopherol/total lipid for the evaluation of vitamin E status in Korean men.

Zine Status of Adult Female in the Taegu Region as Assessed by Dietary Intake and Urinary Excretion: Hyun Mee Oh, Jin Sook Yoon; Korean J Community Nutr 1997;2(1):52-62. Published online February 28, 1997

Abstract PDF: This study was intended to examine the zinc status of free-living adult women living in the Taegu region. Zine intake of 102 female subjects was measured by food frequency method for 3 consecutive days. Urinary zine was assessed from urine samples collected fir twenty four hours. Average dietary zinc intake of adult female subjects using food record was 5.9+/-1.8 mg which was 49% of Korean RDA. When zine intake by frequency method was higher than by food record. Average urinary zine intake by frequency method was higher than that by food record. Thus, it appeared that zinc intake by frequency method was higher than that by food record. Average urinary zinc excretion of 102 adult female subjects was 0.28+/-0.16 mg, which belonged to marginal zinc deficiency range. Fifty nine of 102 subjects showed marginal zinc deficiency as assessed by urinary zinc excretion. If we compare the zinc status of adult female subjects by age group, zinc intake in the 50s was significantly higher than any other age groups. However, there were no significant differences in zinc status according to BMI groups and BMI groups. Significant correlations were found between zinc intake and energy, protein, carbohydrate and fat intake. Based on dietary zinc intake and urinary zinc, we concluded that zinc status of adult female living in the Taegu region is marginally deficient.

Nutritional and Health Status of Korean Elderly from Low-income, Urban Area and Improving Effect of Meal Service on Nutritional and Health Status - V. The Effect of Meal Service for One Year on Nutritional and Health Status: Sook Mee Son, Yaung ja Park, Jae Ok Koo, Yoon Na Lee, Hye Young Yoon; Korean J Community Nutr 1997;2(1):63-73. Published online February 28, 1997

Abstract PDF: This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

A Study on the Perception and Consumption of Imported and Organic Produce of Urban Housewives: Tai Sun Hyun, Wan Soo Kim; Korean J Community Nutr 1997;2(1):74-85. Published online February 28, 1997

Abstract PDF: To investigate the perception and consumption of imported and organic produce, a survey was conducted using a questionnaire in Seoul, Taejon and Cheongju from February to March in 1995. The responses of 350 housewives were analyzed. Most of the subjects (96.8%) know an increase of imported produce, and 86.3% thought that imported produce was not safe. Ninety-two percent of the subjects preferred domestic produce to imported produce. The reasons were for the support of domestic farming (36.7%), hazardous chemicals in imported produce (25.0%), good taste (24.1%) and high quality of domestic produce (13.1%). Seventy-eight percent of the subjects had purchased imported produce. The reasons for purchase were cheap price (67.7%), high quality (16.2%), and good taste (5.4%). Imported produce were purchased in the following order ; fruits such as banana, kiwi, orange and grapefruit, seasonings such as garlic and sesame, vegetables such as onion, braken and green onion, and beans and grains such as soybean, red bean, and barley. Most of the subjects (94.3%) had been informed on organic produce. Among these, 45.2% obtained the information by TV or radio. However, son for purchase was low residual chemicals (64.6%). The reasons against purchase were inconvenience of purchase (42.3%), high price (25.4%), and disbelief of low residual chemicals (19.7%). Therefore, domestic produce should be good in quality and taste, and be safe without residual chemicals in order to compete with imported produce with cheap price. Informations on organic and imported produce should be provided to consumers, and the distribution system of organic produce should be improved for consumers convenience.

Effects of Nutrition Education on Nutrition Knowledge, Dietary Attitudes, and Food Behavior of College Students: Kyoung sin Lee, Ki Nam Kim; Korean J Community Nutr 1997;2(1):86-93. Published online February 28, 1997

Abstract PDF: The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitudes, and food behavior of college students. The subjects of this study were 350 college students attending a university. The education group students received nutrition education three hours per week during a 4-week period offered in a 'Home Economics' course. A total of 150 students in the education group and 200 students in the non-education group completed pre-test questionaires examining nutrition knowledge, dietary attitudes, and food behaviors. Major findings were as follows : nutrition knowledge, and food behavior of the education group were improved compared to the non-education group. But significant changes were not observed in dietary attitudes in the education group. There were higher correlations between nutrition knowledge and dietary attitudes score, and between dietary attitudes and food behavior score at the posttest than those at the pretest. These results suggest that nutrition education for college students can effectively improve their nutrition knowledge and food behaviors.
