The purpose of this study was to investigate the relationships among serum adiponectin, leptin and vitamin D concentrations and the metabolic syndrome in Korean farmers. 105 (26 males, 79 females) farmers (39~78 years, mean age 59.4 +/- 9.6 years) in Gangwon - area were included in this study. Anthropometric measurements and biochemical blood analysis of subjects were carried out. The prevalence of obesity, abdominal obesity, hypertension, diabetes, hypertriglyceridemia, hypercholesterolemia and hyper LDL-cholesterolemia, metabolic syndrome were 51.9%, 65.7%, 49.5%, 15.3%, 17.3%, 13.5%, 11.5% and 40.9%, respectively. Serum adiponectin and leptin levels (8.90 microg/ml and 12.6 ng/ml) of females were significantly higher than those (6.49 microg/ml and 4.88 ng/ml) of males. But there was no significant difference in 25(OH)vitamin D concentration between males (15.4 ng/ml) and females (16.9 ng/ml). In the subjects with metabolic syndrome, the adiponectin levels were significantly lower and leptin levels were significantly higher than those of the subjects without metabolic syndrome. Serum adiponectin level had positive correlations with HDL-cholesterol level (r = 0.325, p < 0.001), but showed negative correlations with triglyceride and fasting blood glucose concentrations, body weight and waist/hip circumference ratio (r = -0.202 ~ -0.317, p < 0.05). Serum leptin and 25(OH)vitamin D concentrations were positively correlated with body fat (kg, %) and BMI, waist and hip circumferences (r = 0.244 ~ 0.682, p < 0.001). The results of this study suggested that adiponectin and leptin levels could be credible indices to predict chronic diseases in farmers. However, further research on vitamin D should be carried out considering another factors.

The aim of this study was to compare nutrient intakes, serum hormones (leptin, adiponectin, insulin), salivary cortisol and alpha-amylase of middle-aged women by the percentage of body fat (% fat). Subjects were assigned to 3 groups by body fat (%) group I (27.5%), group II (32.5%), group III (37.7%). WHR of group II (0.97) was significantly higher than of group I, III (0.95) (p < 0.05). Nutrient intakes were not different among 3 groups. Serum leptin levels of group III (16.53 microgram/ml) were higher than in group I (10.07 microgram/ml), group II (12.24 microgram/ml) (p < 0.05). Salivary cortisol levels of group II (0.39 microgram/dl) were higher than in group I (0.17 microgram/dl) and group III (0.15 microgram/dl) (p < 0.05). Adiponectin concentrations were negatively correlated with TAS (r = -0.29) and positively correlated with HDL cholesterol (r = 0.27). Insulin levels were negatively correlated with total cholesterol (r = -0.33), Zn intake (r = -0.31) and positively correlated with WHR (r = 0.31). The overall anthropometric indices showed positive relations with leptin levels. Salivary cortisol levels were positively corelated with WHR (r = 0.28), total cholesterol (r = 0.31), MDA (r = 0.29) and intakes of SFA (r = 0.35) and MUFA (r = 0.3). Salivary amylase levels were positively correlated with overall nutrient intakes (energy, CHO, fat, cholesterol. Fe, SFA, MUFA, Zn, Na, vitamin B2, r = 0.24-0.5) and was negatively correlated with HDL cholesterol (r = -0.34). These results suggested that 1) WHR would be a helpful index in the assessment of metabolic risk diseases. 2) Understanding of individual stress exposure should be considered in developing strategies for prevention and treatment of obesity.

Obesity is characterized by increased storage of fatty acids in an adipose tissue and closely associated with the development of insulin resistance and cardiovascular diseases (CVD) through secretion of adipokines. This study was done to compare serum insulin, leptin, adiponectin and high sensitivity C-reactive protein (hs-CRP) levels according to body masss index (BMI) in Korean adult women aged 19 to 50. In addition, we examined the association of BMI, serum lipids and Homa-IR with serum adiponectin, leptin and hs-CRP levels. The subjects were divided into 3 groups by their BMI, normal weight (BMI < or = 22.9, n = 30), overweight (23.0 < or = BMI < or = 24.9, n = 71) and obese group (25.0 < or = BMI, n = 59). Serum levels of total-cholesterol, TG, and LDL-cholesterol were significantly higher in obese group than in normal weight group. LDL/HDL ratio and AI were significantly higher in obese group than in normal or overweight group. Fasting serum levels of glucose and insulin and Homa-IR as a marker of insulin resistance were significantly higher in obese group than in overweight group. Serum leptin level was significantly higher in obese group while serum adiponectin level was significantly lower in obese group compared to other two groups. hs-CRP was significantly increased in obese group. Correlation data show that serum adiponectin level was positively correlated with serum HDL-cholesterol level and was negatively correlated with BMI, WC, TG, LDL-cholesterol, Homa-IR, hs-CRP and leptin. In addition, serum leptin level was positively correlated with BMI, WC, glucose, insulin, Homa-IR and hs-CRP. These results might imply that the regulation of key adipokines such as adiponectin might be a strategy for the prevention or treatment of obesity-associated diseases such as diabetes and CVD.

This study was to investigate the effects of a silk peptide, and prune and raspberry mixture on the body fat, serum lipid composition and fat distribution in Korean women during the time they received these supplements. During the 4 month period of this research (June to October, 2002), 75 women (average age 22.9 yr) were selected as subjects. Their nutrient intake was investigated by use of a questionnaire and the 24-hour recall method. Antropometric assessments of the subjects were investigated by using the SBIA Method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: their mean body weight was 59.3 kg, their mean body height was 161.7 cm and their mean Basal Metabolic Indices (BMI) was 22.7. The status of their dietary fiber intake significantly increased (p<0.05) after use of the supplements. Their body fat significantly decreased following the 3rd stage of supplementation (p<0.05), and their percent of body fat signiflcantly decreased after supplementation (p<0.05). Their triceps and suprailiac circumference significantly decreased following the 3rd stage of supplementation (p<0.05). Their waist circumferences and waist-hip ratios (WHR) significantly decreased after both the 2nd and 3rd stage of supplementation (p<0.05). Their total cholesterol significantly decreased following the 3rd stage of supplementation, as compared to their baseline results and those obtained following the 1st stage of supplementation (p<0.05). Their LDL-cholesterol and LDL/HDL ratios significantly decreased following the 3rd stage of supplementation, as compared to their baseline results and those obtained following the 1st stage of supplementation (p<0.05). Their 4-HNE and total antioxidant statuses significantly decreased following the 2nd and 3rd stage of supplementation, as compared to their baseline results and those obtained following the 1st stage of supplementation (p<0.05). Their 2nd stage supplementation results were significantly negatively correlated with their triceps measurements and WHR (p<0.05). Their 3rd stage supplementation results were significantly negatively correlated with their anterior thigh measurements (p<0.05). The above results show that prune, raspberry, silk peptide and dietary fiber supplementation to a routine diet improves body fat distribution, total cholesterol, and triglyceride levels. The decrease of abdominal fat and WHR were especially noteworthy. This implies a decrease of risk factors.
The purpose of this study was to investigate the relationship among serum leptin, nutritional status, and the obesity indices of 55 obese children in Daegu and Kyungpook area. Obesity was defined as fat percentage that exceed 25% of body fat mass. Energy and nutritional status were tended to be low, and dietary intake of calcium and iron were less than any other nutrients in all the subjects. Especially, beverage intake of obese group was more than non-obese group.
The leptin level were significantly correlated with %RDA of energy (0.41, p < 0.001), protein (0.44, p < 0.001), phosphate (0.40, p < 0.001), iron (0.37, p < 0.001), vitamin A (0.31, p < 0.01), thiamin (0.40, p < 0.001), riboflavin (0.26, p < 0.05), niacin (0.51, p < 0.001), and vitamin C (0.24, p < 0.05). The leptin level were significantly correlated with MAR (mean adequacy ratio, r = 0.43, p < 0.001) and INQ (index of nutrient quality) of thiamin (r = 0.22, p < 0.05). Multiple regression analysis showed that %RDA of niacin in obese group (R2 = 0.208, p = 0.001) and total subjects (R2 = 0.257, p = 0.000), MAR (p = 0.003) and INQ (p = 0.048) of niacin in obese group (R2 = 0.255) and MAR (p = 0.000) and INQ of Ca (p = 0.024) in total subjects (R2 = 0.231) may be important independent predictors to leptin level. MAR showed a significantly positive correlation with %fat (r = 0.42, p < 0.01), BMI (r = 0.46, p < 0.01), RW (r = 0.44, p < 0.01), WHR (r = 0.39, p < 0.01) and, %RDA (p < 0.05, p < 0.01). These data indicated relationships among leptin level, nutrient intake, %RDA, MAR, and INQ in children.
The purpose of this study was to investigate the relationship among eating habits, eating behaviors, obesity indices and serum leptin levels of 97 school children in the Daegu and Kyungpuk areas. The subjects consisted of 42 boys and 55 girls from the 4th and 5th grades. The prevalence rate of obesity was 63.6% in the males and 36.4% in the females. The nutritional status of the subjects was assessed using 24-hour dietary recalls and blood analyses. The mean serum leptin levels of the obese group (12.84 +/- 6.97 ng/ml) were significantly higher than those of the non-obese group (2.43 +/- 1.53 ng/ml)(p < 0.001). The mean eating behavior scores and MAR were significantly different in the two groups. Nutrient intakes were low and fell short of the RDA. Serum leptin levels showed a significant negative correlation with eating habit (r = -0.24) and eating behavior scores (r = -0.40)(p < 0.05, p < 0.001). It was speculated that nutritional intervention and education about the appropriate nutrient intake requirements of developing children might be necessary.
