The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI): underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.

The purpose of this study was to investigate the change in food habits of girl students 1985 and 1998. A similar study had been conducted in 1985 and this study was carried in May, 1998 using the questionnaires. The subjects were 746 female students in middle school, high school and university students living in Jeonbuk region. The average score of food habit was 4.11+/-1.63 out of a possible 10. This aversge is lower than the 4.91 score in 1985, especially the score of university students lowered from 4.80 points to 3.52+/-1.58 points. The correlation coefficient between the score of food habit and standard of living, utilizing increase as compared with the 54.9% in 1985. The most preferred side-dish changed from fried food to Kimchi. The preference of snacks was not changed. Eating bread increased at breakfast but eating noodles increased at lunch. University students' lunch basket preparation ratio decreased from 32.6% to 3.3%, so they had more noodles at refectory than lunch basket. The reason for skipping breakfast did not changes, but skipping lunch changed from annoyance due to lunch basket preparation to lack of time and no appetite. Skipping supper was changed from missing time to weight control. Having supper at home decreased from 96.6% to 75.9%. Substitution food on no preparation of lunch basket was changed from bread to noodles. The preference for biscuits and snack did not changes but fewer students preferend bread and fried food. In order to improve the nutritional status of the girl students, they must establish good food habits, especially by eating 3 regular meals per day and balancing their diet they should also be notified that severe weight control is very harmful for health.

OBJECTIVES: A majority of South Korean adolescents experience chronic sleep-deprivation due to social jet lag. In this study, we investigated gender differences in the relationship between social jet lag, depression, and obesity in Korean children and adolescents. METHODS: Our sample consisted of 4,380 adolescents (elementary school cohort n=2,141, middle school cohort n=2,239) who participated in the Korean Children and Youth Panel Survey. In order to analyze the gender differences in the relationship between sleep time difference, obesity and depression, t-test and chi-square test were utilized. RESULTS: Both cohorts revealed that the difference in weekday/weekend sleep duration (2.19+/-1.42 vs. 1.68+/-1.36, p<0.001) and depression levels (20.77+/-6.29 vs. 18.87+/-6.06, p<0.001) was significantly higher in girls than boys. However, body mass index was higher in boys than girls (20.86+/-3.42 vs. 20.04+/-2.51, p<0.001). Chi-square test revealed there was a significant difference between gender and weekday/weekend sleep discrepancy group (cutoff >2 hours). Both elementary school [chi2 (1)=8.73, p<0.05] and middle school cohorts [chi2 (1)=61.29, p<0.001] showed significant gender differences. CONCLUSIONS: There were especially more girls who reported a discrepancy of 2 or more hours of weekday/weekend sleep duration. In summary, intervention for social jet lag may be important to consider in adolescents.

PURPOSE: This study aims to investigate gender differences in the association between depressive symptoms and weight, weight perception, and body satisfaction among Korean adolescents. METHODS: A secondary data analysis was performed on data from 33,374 adolescents who participated in the 2015 Adolescent Health Behavior Online Survey. They were classified as underweight, normal weight, or overweight/obese; weight perception was classified into perception of being underweight, normal weight, or overweight/obese; and weight satisfaction into desire to gain weight, satisfied, and desire to lose weight. RESULTS: Among boys, perception of being underweight (adjusted odds ratio [AOR]: 1.20, 95% confidence interval [CI]: 1.07~1.35) and desire to gain weight (AOR: 1.45, 95% CI: 1.30~1.62) were associated with depression. Among girls, perception of being overweight or obese (AOR: 1.18, 95% CI: 1.07~1.29) and a desire to lose weight (AOR: 1.30, 95% CI: 1.18~1.42) were associated with depression. CONCLUSION: Gender differences were observed in the association between weight perception and depression in adolescents. The perception of being underweight among boys and the perception of being overweight/overweight among girls were associated with depression. Thus, gender-specific intervention programs to correct weight perception and weight satisfaction are needed in order to relieve depressive symptoms in adolescents.

This study examined the effect of self-perception of health and related factors of flood life and disease on health floods intakes among the middle aged(150 men and 159 women) in the Jeonbuk region. The health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), nutritional supplements(NS), and other manufactured health foods supplements(MHFS). Differences of BMI and self-perception for body shape was that overweight was 30% in men and 24.5% in women on BMI, but conversely was 21.3% in men and 43.4% in women on self-perception for body shape. Men thought themselves more than normal weight, but women thought themselves less than normal weight for the criteria of normal weight. Consumption of CM was high in the overweight group on BMI and was a low in the overweight group on self-perception for bodyshape Men thought themselves better than women and those in their 40's thought better than those in their 50's on self perception of health status, and women were better than men on self-perception of food habits. The difference of health foods intakes according to the self-perception of health status and food habits was not significant. The points of food habits, food attitude and nutrition knowledge were 11.21 +/- 2.43, 68.18 +/- 15.56 and 15.53 +/- 1.59 in women and 10.49 +/- 2.71, 67.53 +/- 14.41, and 15.11 +/- 1.79 in men respectively. The points of all were higher for women than for men. Consumption of CM (p<0.01) and TF(p<0.01) were a low in groups that scored high points on nutrition knowledge. The points of climacteric symptoms were that men were 48.36 +/- 6.30 and woman were 46.43 +/- 6.70. Men thought themselves in good condition more than women(p<0.01), and those in their 40's thought themselves in good condition as opposed to those in their 50's in men(p<0.05). Consumption of TF and NS were high in the low points group on climacteric symptoms(p<0.01). Women were higher than men on morbidity, but men were more than women on cases of liver disease(p<0.01). Consumption of CM was high in the liver disease group(p<0.05), MHFS was high in the kidney disease group(p<0.05), TF and NS were hgih in the bone disease group(p<0.05) and NS was hgih in the endocrine disease group(p<0.05). People in their 40's were higher than those in their 50's in men on morbidity of cold(p<0.05), women were higher than men by about 2 times on constipation (p<0.01), those in their 40's were higher than those in their 50's in mein on gastritis(p<0.05). Consumption of NS was highest for those with diseases in respiratory organs and gastrointestinal tracts. This study suggests that nutritional education for the right recognition of self-perception of health status and food habits, and nutrition knowledge are needed to select for health floods. Consumption of health foods was different according to kinds of diseases. Thus, recognition of etiology, symptoms and dietetics of diseases is needed to select adequate health foods for diseases in middle age.

The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat (%Fat); normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.

This study examined health foods intakes and related variables among the middle aged(150 men and 159 women) in the Jeonbuk region. Health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), vitamin or mineral supplements(VMS), and other manufactured health food supplements(MHFS). The number of people taking health foods were higher for those in their 50's than in their 40's. The consumption rate of TF in men was the highest among health foods, this result had significance. The reasons for taking health foods were recovery from fatigue, supplement of nutrients and making smooth body activity in general, but TF was used to increase of vigor. The consumption rate of health foods was a little different according to social-economic factors, namely, the consumption rate of CM was higher in people in rural than urban areas, those who graduated from middle school than university, blue color & self-employed as opposed to housewives and service workers, low level income than high level income, and Buddhism and no religion than Christian. The consumption rate had a correlation with the habits of smoking, alcohol drinking and exercise ; namely, the consumption rate of CM was higher than VMS and MHFS on smokers and alcohol drinkers. The more the frequency of exercise, the higher the consumption rate of TF, but the duration of the exercise was not correlated. This study suggests that middle aged people need nutritional education for the right recognition and selection of health foods and to consider the nature of each type of health foods.

PURPOSE: The purpose of this study was to identify factors associated with intermittent and light smoking among Korean high school students. METHODS: In this cross-sectional study, we employed secondary data from the 2015 Korea Youth Risk Behavior Web-Based Survey, and used the biopsychosocial model as a framework. The analysis was performed using the data of 2,851 high school students who smoked. We defined intermittent and light smoking as smoking on 1 to 29 days in a 30-day period and no more than 10 cigarettes per day. A logistic regression analysis using the complex samples procedure was conducted. RESULTS: Among all the participants, 1,231 (43.2%) were intermittent and light smokers. Factors significantly predicting intermittent and light smoking were gender and grade (biological factors); subjective stress (psychological factor); and mother's smoking, sibling's smoking and academic achievement (sociocultural factors). CONCLUSION: In smoking cessation programs, health care providers both at school and in the community should consider the unique biological, psychological, and sociocultural characteristics of intermittent and light smoking behavior among high school students.

It is a common clinical practice to recommend taking iron supplements for pregnant women during gestation. Although it is required to ensure adequate iron stores during pregnancy, there has been some debate over the interference effects of excessive iron load, because it is possible to compete in the transport in the intestine and placenta and in binding to serum proteins of other trace minerals. In this study, maternal and neonatal serum concentrations of Fe, Zn, Cu, Se, Cr, Mn, and Co were assessed along with maternal Fe intakes. A total of 124 pregnant women and their term neonates participated voluntarily in this research. The women were divided into one of the three groups {high Fe intake (HFI), median Fe intake (MFI), and low Fe intake (LFI)} by their total Fe intakes and one of the two groups (Anemic and Normal) by their Fe nutritional status. All the data were compared among the three groups and between the two groups also. Total Fe intakes of HFI, MFI, and LFI groups were 140.8 +/- 76.1, 68.0 +/- 11.2, and 30.2 +/- 8.6 mg/day, respectively. Those of Anemic and Normal groups were 90.1 +/- 74.8 and 86.6 +/- 46.8 mg/day, respectively. Maternal Hb concentration and Hct were not significantly different among HFI, MFI, and LFI groups but those were significantly different between Anemic and Normal groups. However, neonatal Hb concentration was not significantly different among HFI, MFI, and LFI groups and between Anemic and Normal groups either. Maternal serum Fe concentrations of the three groups, HFI, MFI, and LFI, were similar but that of Anemic group was significantly lower compared to Normal group. However, there was no significant difference in neonatal serum Fe concentrations among the three groups and between the two groups either. Serum concentrations of the other trace minerals in both mothers and neonates were not significantly different among HFI, MFI, and LFI groups and between Anemic and Normal groups. In addition, in the maternal serum, Fe concentration was positively correlated to Zn and Se concentration, respectively. As for the neonatal serum, Fe concentration showed a positive correlation to Zn, Cu, Mn, Se, and Co concentration, respectively. No trace mineral concentration was found to correlate negatively to Fe concentration in both maternal and neonatal serum, The results in this study indicate that Fe intakes of pregnant women, even if it is considerably above the level of estimated average requirement (EAR), may not affect serum Fe concentration in both mothers and neonates. In addition it might not influence adversely on the availability of other trace minerals including Zn and Cu in both mothers and neonates.
