Many epidemiological and observational studies show that distorted body image of normal body weight is widespread among Korean young females. This study was performed to evaluate the prevalence of overweight and underweight of young females and, to compare nutrient intakes, body composition, serum indices (lipids, MDA: Malondialdehyde, TAS : Total Antioxidant Status) with different BMI groups. The subjects were 75 university students in Seoul. We divided the subjects into 3 groups according to their BMI by IOTF guideline (UW: underweight group, BMI < 18.5, NW: normal body weight group; 18.5 $\leq$ BMI < 23.0, OW: overweight group; BMI $\geq$ 23.0). Data on dietary intakes, body compositions and serum indices were obtained in 3 groups. Differences on all of the above variables were assessed by body weight groups. Using IOTF guidelines, the prevalence of overweight and underweight in young females were 23%, 61%, 16% respectively. $\beta$-carotene and vitamin A intake of UW were significantly higher than that of NW (p < 0.05). Fiber intakes of NW was significantly higher than that of W (p < 0.05). But intakes of energy and the other nutrients were not significantly different among BMI groups. Calcium and folate intakes were 75%, 61% of KDRIs. Serum TGs were significantly higher in OW than that of NW, UW (p < 0.05), but level of MDA and TAS were not significantly different. The association of overweight and low intake of $\beta$-carotene and vitamin A may be one of many factors predisposing obese females to a high risk of oxidative stress later in life. This requires urgent nutritional intervention programs involving enough intake of fruit and vegetables, with modification of inappropriate dietary habits.

Objectives: The aim of this study was to evaluate the effect of body weight status and sleep duration on the discrete-time hazard of menarche in Korean schoolgirls using multiple-point prospective panel data. Methods: The study included 914 girls in the 2010 Korean Children and Youth Panel Study who were in the elementary first-grader panel from 2010 until 2016. We used a Gompertz regression model to estimate the effects of weight status based on age-specific and sex-specific body mass index (BMI) percentile and sleep duration on an early schoolchild's conditional probability of menarche during a given time interval using general health condition and annual household income as covariates. Results: Gompertz regression of time to menarche data collected from the Korean Children and Youth Panel Study 2010 suggested that being overweight or sleeping less than the recommended duration was related to an increased hazard of menarche compared to being average weight and sleeping 9 hours to 11 hours, by 1.63 times and 1.38 times, respectively, while other covariates were fixed. In contrast, being underweight was associated with a 66% lower discrete-time hazard of menarche. Conclusions: Weight status based on BMI percentiles and sleep duration in the early school years affect the hazard of menarche.

Objectives : The purpose of this study is to investigate the effect of fasting therapy on the changes of body composition in obese adolescents. Methods : We examined the body composition of obese adolescents three times; before fasting, on the second refeeding day, two or four weeks later. Results : Body weight, body mass index(BMI), basal metabolic rate(BMR) and lean body mass (LBM) were decreased during the fasting, whereas percent-fat was increased. After fasting, patients have the dietary period. During this period BMR and LBM were increased and the decrease of percent-fat was continued. Conclusions : It seems that fasting therapy with keeping up well-controlled dietary period and receiving oriental medical management can be useful to decrease percent-fat in obese patients.

Purpose: The purpose of this study was to examine the relationship among the levels of total serum cholesterol level, blood pressure, body mass index, and lifestyle. Method: This study was designed as a descriptive correlation study. Subjects were 972 adults participated voluntarily living in GyeongNam. The height, weight, blood pressure and fasting serum cholesterol were measured. Body mass index was caculated. Information on general characteristics (age, gender, education, job, family history) and life style(cigarette, alchol, sleeping time, regular exercise, meal pattern, peppery, salty, sweetness, vegetable diet, meat diet) were collected using a questionnaire by interviewing method. Result: The mean value of total serum cholesterol was $197{\pm}36.4mg/dl$(mean; $189{\pm}36.7mg/dl$, women; $202{\pm}35.1mg/dl$). By simple analysis, the serum total cholesterol according to general characteristics features was statistically significant in age(F= 6.765, p=000) and gender (t=5.372, p=.000). Total serum cholesterol levels increased significantly with increasing BMI. The serum total cholesterol according to life style features was statistically significant in cigarette(${\chi}^2=12.12$, p=.016), exercise(${\chi}^2=6.335$, p=.042), salty taste(${\chi}^2=18.801$, p=016), vegetable diet (${\chi}^2=19.488$, p=012). The most affecting factor which total serum cholesterol factor was BMI(${\beta}=.151$, p=.000). Conclusion: The significant risk factors relating to serum total cholesterol were age, gender, BMI, smoking, and exercise. Therefore, for the reduction of serum total cholesterol level, it is recommended that nursing intervention for the prevention of obesity, change of life style should be implemented.

It is important for young adults to establish good dietary behavior for healthy life. The prevalence of obesity in college students has increased gradually. The obesity is one of the most prevalent health problems in S. Korea. Moreover, obesity is closely related with the disease such as cardiovascular disease, diabetes mellitus. The purpose of this study was to evaluate health practice, serum components and nutrient intake of the college students according to Body Mass Index (BMI) level. 400 male and female freshmen students in 4 year university located near to Seoul metropolitan area were surveyed respectively through the health check-up procedure for college entrance in February. Survey was carried out for them by questionnaires, including a 24-hour dietary recall and anthropometric measurements. Blood samples were obtained while fasting. Nutrient intake was expressed by DDS(Dietary Diversity Score by 5 food groups) and DVS(Dietary Variety Score). Nutrition level was analyzed by Can-Pro (Korea Nutrition Association). And for the quantity intake, percentage ratio against daily requirement(by KDRIs) and MAR(Mean Adequacy Ratio) were calculated. Underweight group($BMI<18.5kg/m^2$), normal weight group($18.5) and overweight group($BMI<23.0 kg/m^2$) were 18.5%, 61.2% and 19.3% respectively. Nutrient intake levels and food intake status were not significantly different among three groups. The mean nutrient adequacy ratio (MAR) was not significantly different by BMI status. Nutrient intakes of calcium, iron, and riboflavin were especially low for all the students. Overweight group showed high blood pressure(120.9/79.3 mmHg) compared with the underweight group (116.4/ 75.8mmHg) but the difference was not significant. The serum triglyceride level in overweight group (94,0mg%) was higher than that in normal (70.9mg%) or underweight group(70.8mg%)(p<0.05). HDL-cholesterol level in overweight (43.8 mg%) group was not significantly different from that in underweight group (45.9mg%). BMI was positively correlated with blood pressure, hemoglobin, and the intake of total fat and cholesterol. But it was negatively correlated with HDL-cholesterol level. With these results overweight group is closely related with the cardiovascular disease risks, such as high blood pressure and high triglycerides and cholesterol. Thus, a health intervention program including weight control is required for young adults.

Background: The aim of this study was to examine the influence of body mass index (BMI) on the development of acute kidney injury (AKI) in critically ill patients in intensive care unit (ICU). Methods: Data of patients admitted to medical ICU from December 2011 to May 2014 were retrospectively analyzed. Patients were classified into three groups according to their BMI: underweight (< $18.5kg/m^2$), normal ($18.5-24.9kg/m^2$), and overweight (${\geq}25kg/m^2$). The incidence of AKI was compared among these groups and factors associated with the development of AKI were analyzed. AKI was defined according to the Risk, Injury, Failure, Loss of kidney function, and End-stage (RIFLE) kidney disease criteria. Results: A total of 468 patients were analyzed. Their mean BMI was $21.5{\pm}3.9kg/m^2$, including 102 (21.8%) underweight, 286 (61.1%) normal-weight, and 80 (17.1%) overweight patients. Overall, AKI occurred in 82 (17.5%) patients. The overweight group had significantly (p<0.001) higher incidence of AKI (36.3%) than the underweight (9.8%) or normal group (15.0%). In addition, BMI was significantly higher in patients with AKI than that in those without AKI ($23.4{\pm}4.2$ vs. $21.1{\pm}3.7$, p<0.001). Multivariate analysis showed that BMI was significantly associated with the development of AKI (odds ratio, 1.893; 95% confidence interval, 1.224-2.927). Conclusion: BMI may be associated with the development of AKI in critically ill patients.

A cross-sectional study to determine dietary intake and plasma triglyceride total cholesterol LDL-cholesterol and HDL-cholesterol of 185K Korean men was conducted across three different age groups The younger group (age 21 to 34) was significantly (p<0.001) taller but showed lower (p<0.05) percent body fat than the older group (age 45 to 60) Weight and body mass index was not different among age groups. Older men showed significantly(p<0.01) lower energy and total fat intake than younger men Besides macronutrients, most participants consumed an adequate amount of micronutrients but calcium consumption of the middle age group (age 35 to 44) was less than 75% of RDA In older men plasma triglyceride(207.8$\pm$155.5 mg/dl) total cholesterol (201.4$\pm$40.0 mg/dl) and LDL-cholesterol(106.0$\pm$32.7 mg/dl) concentrations were significantly hight(p<0.001) than in younger men wereas no significant difference was observed in HDL-cholesterol concentration Subjects with a higher BMI(bMI$\geq$25.0) showed significantly higher (p<0.001) triglyceride(200.2$\pm$107.6 mg/dl) total cholesterol(211.0$\pm$40.1 mg/dl) LDC-cholesterol(118.16$\pm$35.5 mg/dl) concentrations and lower(p=0.001) HCL-cholesterol concentration (52.8$\pm$15.9 mg/dl) than subjects with lower BMI(BMI<23.0) Dietary intake of fat cholesterol did not show significant associations with any of the plasma lipid profiles. However, anima fat intake was significantly (p<0.05) correlated with plasma total cholesterol and triglyceride concentrations in the older age group. On the hand percent body fat was correlated (p<0.05) with all of the plasma lipid and lipoprotin concentrations examined for all age groups Results indicate both dietary intake and percent body fat are important determinants of the plasma lipid concentrations is the elderly but only percent body fat or body mass could be valid predictors for the plasma lipid concentrations of the younger age group.

A study was conducted to investigate the anthropometric indices, fat distribution, eating habits and levels of daily physical activity based on the body mass index (BMI ; kg/㎡) of 180 female college students. This stady was based on survey 2001 using a questionnaire. The results are as follow ; The mean age, height, weight and BMI were 20.41 ${\pm}$ 1.82 years, 161.86 ${\pm}$ 4.51cm, 53.49 ${\pm}$ 7.02kg, and 20.43 ${\pm}$ 2.65kg/㎡, respectively. The group with BMI of under 20 (the lean group) comprised 48.9% : the group with BMI of 20 to 25 (the normal group) comprised 44.4% and the group with BMI of over 25 (the obese group) comprised 6.7% of the subjects. Even though the lean and the normal groups were determined according to BMI. 12.5% of the lean group and 31.3% of the normal group had more than 25% body fat. Of the students, 11.5% of the lean group, 25.0% of the normal group and 58.3% of the obese group had of more than 0.8 waist/Hip Ratio (WHR). The medical problems suffered by the subjects were constipation (24.4%), gastroenteritis (20.6%), anemia(15.0%) and edema(13.3%), which was a result of their eating habits. Out of all the subjects, 27.2% ingested their meals irregularly, 74.4% skipped breakfast, and 92.4% of the lean group, 89.2% of the normal group and 81.8% of the obese group ingested snacks on a daily basis. Their favorite types of snacks were cookies breads and cakes (33.7%), spicy sliced rice cakes pork sausage and boiled fish cakes (18.5%), fruits (15.2%), juices and sodas (13.5%) and hamburgers and pizzas (3.9%). Their consumption of high calorie and processed foods was high, Of the subjects, 38.9% ate out daily. 45.1% had tried weight loss. Those with large upper bodies comprised 11.5%, large intermediate bodies 18.5% and large lower bodies 69.0%. Most of the students were dissatisfied with their body snaps. Of the subjects, 95.1% exercised irregularly. Daily physical activity tended to increase significantly with an increase in BMI : the lean group's average energy consumption was 1509.40㎉ the normal group's was 1792.21㎉ and the obese group's was 2334.63㎉, which were below the recommended value. This study suggests that the maintenance of an ideal weight, the improvement of eating habits and adequate exercise are needed for female college students to improve their health and nutritional status.
