Background: Abdominal obesity as measured by waist-to-height ratio (WHtR) may have stronger and inverse associations with cardiovascular (CV) health than overall obesity as measured by body mass index (BMI). However, there was some challenges for controversies. We aimed to examine the associations of WHtR and BMI with CV health among Korean children using data of the 2010-2012 Korea National Health and Nutrition Examination Survey. Methods: A cross-sectional study was conducted with the sample of 2,363 children by analyzing by gender and two-age groups (10-12 and 13-18 years). Overall obesity was categorized into 3 groups by BMI percentile: non-overweight (<85), overweight (${\geq}85$), and obesity groups (${\geq}95$). Abdominal obesity was categorized into 2 groups by WHtR: normal (<0.5) and abdominal obesity groups (${\geq}0.5$). The CV health score was defined as a z-score by calculating the sum of 7 CV factors. Results: The overweight/obesity groups had significantly lower CV health scores than the normal group (P<0.05) in boys and girls aged either 10-12 years or 13-18 years after adjusting for covariates. The abdominal obesity group also showed significantly lower CV health scores than the normal group (P<0.05) in all the groups; this significant association remained significant in boys aged 13-18 years even after further adjusting for BMI category (P<0.01). Conclusions: Among boys aged 13-18 years, abdominal obesity as measured by WHtR was significantly and inversely associated with CV health, independent of BMI category. Therefore, it should be considered to assess the level of abdominal obesity as a measure of CV health in late adolescent boys.

This study was carried out to investigate the effects of mulberry-leaf powder Tofu (MPT) on serum lipids profiles, Ca levels, Ca/P ratio and Pb levels in 30 middle aged obese women living in the Choongnam area. 100 g/day MPT was consumed for 4 weeks. The nutrient contents per 100 g MPT were 86.71 kcal (energy), 8.98 g protein, 0.53 mg fiber, 211.33 mg Ca and 1.59 g fat. Anthropometric measurements, 24 h recall dietary intakes, serum levels of protein, albumin, glucose, Ca and Pb, lipid profiles (cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol), and the Ca/P ratio were analyzed before and after consumption of MPT. After consumption of MPT, there were no significant differences in anthropometric measurements, the levels of serum protein, albumin, glucose, total cholesterol, HDL-cholesterol, lipase activity, HTR (HDL-cholesterol/total cholesterol), CRF (cardiac risk factor), Ca, Ca/P ratio and Pb. There were decreases in the levels of serum triglyceride, LDL-cholesterol, AI (atherogenic index) and LHR (LDL-cholesterol/HDL-cholesterol). Significantly increased dietary intakes of plant protein, total Ca, and plant Ca were observed.

This study was performed to document the association between eating behaviors and major risk factors for cardiovascular diseases. Those who stated that they ate a daily breakfast for male and female were 88.6% and 96.0%, $1{\sim}2$ times a week were 9.1% and 2.0%, $3{\sim}4$ times a week were 2.3% and 2.0%, respectively. Those who stated that they were overeating of $0{\sim}1$ time a week for man and female were 80.7% and 89.9%, overeating of $2{\sim}3$ times a week were 19.3% and 10.1%, respectively. Those who said that they were regular of meal time for man and female were 38.6%, and 37.4%, sometimes irregular of meal time were 14.8% and 19.2%, irregular of meal time were 46.6% and 43.4%, respectively. Those who said that they were light of eating volume for man and female were 20.5% and 25.3%, moderate of eating volume were 69.3% and 61.6%, heavy of eating volume were 10.2% and 13.1%, respectively. Those who said that they were very fast of eating speed for man and female were 15.9% and 8.1%, fast of eating speed were 51.1% and 34.3%, moderate of eating speed were 4.5% and 20.2%, slow of eating speed were 17.0% and 14.1%, and very slow of eating speed were 11.4% and 23.2%, respectively. Higher frequency of breakfast a week resulted in higher serum total cholesterol and blood sugar for the daily eating group for both genders with women having high LDL-cholesterol and HDL-cholesterol. Both group had high HDL-cholesterol and low blood sugar with less number of overeating, with men having low triglyceride and LDL-cholesterol. With regular meal, both group had low triglyceride, total-cholesterol, atherogenic index, and blood sugar with women having low LDL-cholesterol. For both groups, the triglyceride, total-cholesterol, LDL-cholesterol, atherogenic index, and blood sugar had higher figures for overeating, with men having low HDL-cholesterol and women having high HDL-cholesterol. This study revealed that less number of overeating, regular mealtime, and less volume of food intake are effective in preventing and treating for the cardiovascular diseases.

This study was peformed to document the association between nutrient intakes, body mass index (BMI), waist/hip ratio (WHR), and a major risk factor for chronic diseases. A three-day dietary intake survey, using a 24 hour recall method, was obtained from 187 subjects aged 46 to 84 (mean age 65.3) living in Wando island area. The average daily mean energy intakes were 1869.0 kcal for male and 1943.9 kcal for female, respectively. Daily intakes of protein for male and female were 28.0 and 30.4 g, and those of fat were 31.5 and 28.51 g, respectively Carbohydrate dependency was decreased with age. Protein dependency was increased with age. The mean intakes of energy, protein, Vit. A, Vit. D, Vit. E, Ca, Zn did not meet Korean RDA for elderly. The level of serum triglyceride was higher in males than in females and showed the tendency to increase with age in both sexes, whereas HDL-cholesterol tended to decrease with age in both sexes. The levels of serum total-cholesterol and LDL-cholesterol were significantly higher in males than in females, particularly in the age of $46\~59$ (p<0.05). The level of atherogenic index (AI) was significantly higher in females than in males, particularly in the age of 80 and over (p<0.05) Based on these results, it is evident that people in island area did not consume enough nutrient. Specially, dietary intake of protein was not adequate. This study implies that triglyceride, total-cholesterol, LDL-cholesterol, AI were increased with increasing age, BMI and WHR.

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.

The effects of an Acanthopanacis cortex water extract on lipid levels, lipid peroxide, total antioxidant status and antioxidant enzyme activities were evaluated in rats fed one of the following diets for six weeks: normal diet and deionized water (ND), normal diet and Acanthopanacis cortex water extract (NDC), high fat diet and deionized water (HFD), high fat diet and Acanthopanacis cortex water extract (HFDC). The food intakes were significantly lower, but the food efficiency ratios were significantly higher in the high fat diet groups. The level of HDL-cholesterol in the plasma was significantly increased and the levels of LDL-cholesterol and triglyceride in the plasma were significantly decreased by the Acanthopanacis cortex water extract in the high fat diet groups. As a a result, the AI (atherogenic index) and CRF (cardiac risk factor) were significantly lower in the high fat diet groups that were treated with Acanthopanacis cortex water extract. The triglyceride and the total cholesterol of the liver were also significantly upregulated in the high fat diet groups, while the total cholesterol of the liver decreased in response to treatment with Acanthopanacis cortex water extract (HFDC). The plasma and liver concentrations of thiobarbituric acid reactive substances (TBARS) were significantly reduced by the addition of Acanthopanacis cortex water extract to the normal diet groups. The total antioxidant status (TAS) in the plasma was significantly upregulated by adding Acanthopanacis cortex water extract to the high fat diet groups. The activities of SOD, catalase and GST were also significantly higher in the Acanthopanacis cortex water extract groups when compared to the ionized water groups. The activity of GSH-Px and the concentration of GSH in the liver were significantly higher following the addition of Acanthopanacis cortex water extract to the high fat diet groups. Taken together, these results suggest that a supplementation of the diet of rats fed a high fat diet with Acanthopanacis cortex water extract improves lipid metabolism, reduces lipid peroxide and improves the activities of antioxidant enzymes, which may have favorable effects on antioxidant systems by improving the total antioxidant status (TAS).
