Obesity rates are increasing worldwide, associated with excess acute and chronic disease risk. In most countries, obesity rates among women exceed rates in men, particularly during the post menopausal years. Many factors affect body weight and appetite, including age, metabolic rate, physical activity level, stress, cultural factors, socioeconomic status, health status and health literacy, diet composition, attitudes, and beliefs. Gender affects appetite and body weight indirectly by altering factors contributing to food choice. However, there is emerging evidence that gender affects appetite and body weight directly, altering the physiological control systems regulating appetite. The follicular menstrual cycle phase (estrogen-rich) is associated with relative suppression of appetite. Lower estrogen levels are associated with increased food intake, body weight gain, and altered body fat distribution in humans and animals. This paper reviews the linkages between estrogen and appetite regulation. While relationships among appetite, body weight, and gender-linked hormones are complex, research elucidating these interrelationships could lead to development of gender-specific treatment approaches for obesity and appetite dysregulation.

Purpose: The purpose of this study was to predict measuring site suited for abdominal skin fold thickness (ASFT) by measuring the distribution of abdominal subcutaneous fat thickness (AScFT) and ascertain the correlations among obesity indicators. Methods: The size of analysis materials was 124 secondary data measured by ultrasonic device, bioelectrical impedance analyzer and caliper. Data were analyzed using t-test, and Pearson's correlation. Results: The average of AScFT was 10.63± 6.79mm with its range 1.39-36.16 mm, and AScFT of female and of central parts were thicker than those of male and outer parts in the abdomen. The average of ASFT was 29.26±12.59 mm. Site 5 on Figure 1 was most similar to the average of AScFT in both sexes. Body mass index (BMI) and waist hip ratio (WHR) were 23.65±3.98 and 0.88±0.05 respectively. The body weight, BMI, WHR, visceral fat, ASFT vs AScFT revealed in significant correlation (r= .29, r= .55, r= .39, r= .33. r= .29). Conclusion: BMI and WHR seem more useful than other obesity indicators, when obesity control is necessary for Type 2 diabetes patients. Site 5 on Figure 1 is most suitable site to measure ASFT.

Purpose: Vitamin D status is associated with several chronic diseases related to obesity. In this study, we evaluate the nutritional status of vitamin D and its relation to obesity indices in Korean women. Methods: A total of 156 healthy women participated. Vitamin D status (serum $25-OH-vitamin\;D_3$ level) and obesity indices (body mass index, body fat mass, waisthip ratio, and body fat percentage etc.) and serum lipid profiles and serum adipokine (leptin and adiponectin) levels were analyzed. Results: The $25(OH)D_3$ level showed an extremely skewed distribution from 4.1 ng/ml to 24.4 ng/ml and mean $25(OH)D_3$ level was $9.0{\pm}4.0ng/ml$. With cut-off level for vitamin D deficiency (< 12.0 ng/ml), insufficiency (12-19.9 ng/ml) and sufficiency (${\geq}20ng/ml$), 77.6%, 19.2%, and 3.2% of subjects showed vitamin D deficiency, insufficiency, and sufficiency status, respectively. The $25(OH)D_3$ level showed positive correlation with weight (r = 0.2461, p < 0.01), body mass index (r = 0.2913, p < 0.001), body fat contents (r = 0.1691, p < 0.05), fat free mass (r = 0.2330, p < 0.01), and waist hip ratio (r = 0.1749, p < 0.05) after adjusted by age. The $25(OH)D_3$ level showed no significant correlation with serum lipid profiles and adipokine levels. Conclusion: Most subjects (76.6%) in this study, who had a vitamin D deficient status and serum $25(OH)D_3$ level, showed positive correlation with several obesity indices, however further research based on a large Korean population is needed to confirm the relationship.

The purpose of this study was to investigate the food habits, nutrient intake, and disease distribution in the elderly (aged over 65 years). The correlation of diseases with anthropometric measurements and nutrients was investigated. The correlation of blood parameters with anthropometric measurements and nutrient intake was also studied. The results are as follow: 1) Most elderly men (68.6%) and women (81.6%) had more than three diseases. The food habits of the elderly women were worse than those of the men. Their intake of protein, calcium, iron, vitamin A, and vitamin $B_2$ were lower than the RDA for those particular nutrients.2) The incidence of gastritis (51.2%) , fatty liver (46.4%) , and hypertension (45.2%) were the highest among elderly men and women. 3) Anemia was negatively correlated with body weight. Hypercholesterolemia was positively correlated with body fat and negatively correlated with intake of calcium, vitamin A, and vitamin $B_2$ . Hypertension was negatively correlated with alcohol consumption. 4) Blood total cholesterol concentration was positively correlated with percent ideal body weight (% IBW) . Blood hemoglobin level was positively correlated with Body Mass Index (BMI) . Systolic and diastolic blood pressure were positively correlated with % IBW and BMI. Blood cholesterol concentration was negatively correlated with the intake of iron, vitamin A, vitamin $B_2$, and cholesterol, and positively correlated with the consumption of alcohol. Blood hemoglobin level was positively correlated with the intake of total calories, carbohydrates, fat, protein, iron, vitamin $B_2$, phosphorus, cholesterol, salt, and alcohol.

This study is to investigate consequent nutrient intake status, Influences of body mass index (BMI) and serum lipid composition, and fat distribution on the cocoon hydrolysate, green tea leaves and dietary fiber supplementation. During 2 months of this research (April to May, 2002), 47 women aged 20 yr-30 yr (average age 26.2 yr) were selected as subjects. Nutrient intake was investigated by questionnaire and 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method (Segmental bioimpedance assay, Inbody 3.0). The results were as follows: mean body weight was 60.7 kg, mean body height 161.7 cm and mean BMI 23.4. Status of energy intakes significantly decreased (p<0.01) and dietary fiber intakes significantly increased (p<0.001) after supplementation. BMI and WHR (waist-hip ratio) significantly decreased (p<0.01) and body fat significantly decreased after supplementation (p<0.001). Total cholesterol and LDL-cholesterol significantly decreased after supplementation (p<0.05). HDL-cholesterol was negatively correlated with BMI and WHR (p<0.01). LDL/HDL ratio was positively correlated with BMI (p<0.01) and WHR (p<0.05). Above results of this study show that low-molecule peptide, green tea leaves and dietary fiber supplementation-added routine diet improves lessening body fat distribution, total cholesterol, LDL-cholesterol. Especially, decrease of abdominal fat and WHR were notable. That meant decrease of risk factors.

Objective: Obesity is closely related to several factors such as genetic factors, energy intake and energy expenditure. It was said that alcohol & food habits were important to formation of obesity. The purpose of this study are to find out the alcohol & food habitual characteristic of obese adult men and to promote the health of these men. Method: From May, 2000 to November, 2001, We collected 75 eases obese patients, who visited to the Health Examination Center Dept. of Kangnam oriental medicine hospital, Dongguk University who took the health examination, and control group who were matched by age and sex. We investigated the alcohol & food habits by questionnaire. Results and Conclusions: 1. The patients over BMI 25 were in excess of the standard of obesity such as Modified Broca $^{\circ}{{\O}}s$ Index. Percent Body Fat, Abdominal Fat Distribution. But, the patients below BMI 20 were normal range of obesity degree. 2. Abdominal Fat Distribution was increased according to age and physical activity was decreased in obese group. 3. The mean of total calory by alcohol in a month was 4324.6kcal in obese group while control group was 2206.8kcal. 4. In the comparison of food habit, obese group is higher than control group in 7 articles of the 13 articles which influenced obesity.

Objective: A number of candidate genes have been in implicated in the pathogenesis of obesity in humans. Tumor necrosis factor-alpha $(TNF-{\alpha})$ is expressed primarily in adipocytes, and elevated levels of this cytokine have been linked to obesity and insulin resistance. Recently, the A allele of a polymorphism at position 308 in the promoter region of $TNF-{\alpha}$ (G-308A) has been shown to increase transcription of the gene in adipocytes. Therefore, we designed this study to test whether obese and non-obese subjects differ in $TNF-{\alpha}$ genotype distribution, and how the genotypes affect anthropometric parameters, including degrees of body mass index (BMI). Methods : The study included 153 obese but otherwise healthy women ($BMI{\geq}kg/m^2$, range 25-54.7, age range 15-40 years) and 82 non-obese healthy women ($BMI, age range 15-40 years). Total fat mass and percent body fat were determined by dual-energy X-ray absorptiometry. Genomic DNA was extracted and used for Ncol restriction fragment length polymorphism (RFLP) based genotyping of $TNF-{\alpha}$. Results: No differences were observed for allelic and genotype frequencies between the obese ($BMI{\geq}25$) and non-obese women. Also, no association of TNF-(l polymorphism was observed with body mass index (BMI) for genotype in obese women. In addition, age, pertent body fat, BMI, and cholesterol levels did not differ by $TNF-{\alpha}$ genotype. However, waist-to­hip ratio (WHR) was significantly lower in subjects with $TNF-{\alpha}$ GA or AA genotype (0.94 0.07 vs. 0.920.03, P<0.005). Conclusion: These results suggest that $TNF-{\alpha}$ promoter polymorphism at position-308 is not a significant factor for BMI, but affects the WHR in obese healthy women from Koreans.

To figure out the causes of obesity against middle-aged women, this study aimed to provide basic data for setting an obesity-related policy through analysis on diverse related factors. Against the healthy middle-aged women who visited 'N' Hospital Health Center in Incheon from April to November 2014, anthropometric assessment, body composition test and abdominal fat distribution test were conducted using Fat-CT. They were carried out against 159 women who agreed with the purpose of the study, using BMD, Q-CT. According to Fat-CT, subcutaneous and visceral types accounted for 39% (76 women) and 61% (119 respondents) respectively. In terms of BMI, 'underweight ($18.5kg/m^2$)' and 'overweight ($25kg/m^2$ or above)' were 13 women (6.7%) and 60 women (30.8%) each with the average of $23.5{\pm}4.11kg/m^2$. Mean while, waist circumference, diastolic blood pressure, systolic blood pressure and neutral fat were statistically significant at the 5% significance level. As getting older, muscle weakness offsets increase in body weight with abdominal obesity. A group with low BMI should also be considered due to increase in waist circumference.

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.
