Comparison of health outcomes according to intervention compliance in male Korean workers with metabolic syndrome

This study examined how achievement of session goals contributes to outcomes of subjects after participation in a 12-week lifestyle intervention program in men with metabolic syndrome (MetS). Thirty office workers with MetS, aged 47.2 +/- 6.6 years, participated in this study, from March to July, 2011. The intervention program included face-to-face counseling five times during the 12-week period. Counselors and subjects designed session goals for each round. The average of the goal achievement rate was calculated based on compliance for each round. The subjects were divided into three groups according to their tertiles of achievement rate: Low-compliance group (LC, 70%). Anthropometry, biochemical index, and nutrient intake were examined at baseline and at the end of the 12-week intervention program. After the intervention, diastolic blood pressure (DBP) showed a significant decrease in the LC group, and waist circumference (WC) showed a significant decrease in the MC group. Systolic blood pressure (SBP), DBP, and low-density lipoprotein cholesterol (LDL) showed a significant decrease in the HI group. Changes in SBP and DBP were significantly lower in the HC group than in the MC group (p < 0.05, p < 0.01). Changes in LDL were significantly lower in the HC group than in the MC group (p < 0.05). Results for intake of total energy, protein, fat, and sodium, as well as rates of carbohydrate and fat intake, showed a significant decrease in all participants (p < 0.05). The change in fiber was significantly higher in the HC group than in the MC group (p < 0.05). The change of fruit serving size showed a significant increase in the HC group (p < 0.01). The number of risk factors for MetS showed a significant decrease in the LC and HC groups (p < 0.05), however, no significant mean differences were observed among the three groups. In conclusion, participation in this intervention program resulted in positive effects on risk factors for MetS, nutrient intake, and dietary habits, especially in the High-compliance group.

Effects of Ethanol Extract of Onion on the Lipid Profiles in Patients with Hypercholesterolemia

It is known that onion increases antioxidative and antibiotic capacity, and decreases blood pressure and cholesterol levels. The study was carried out to investigate whether ethanol extract of onion can enhance blood lipid profiles in hypercho-lesterolemic patients. Fourty three hypercholesterolemic patients were randomly divided into 2 groups ;25 in controls and 18 in experimental group. The control group was offered to take placebo for 4 weeks (200 ml/day ), and experimental group was offered to consume ethanol extract of onion for 8 weeks (200 ml/day that corresponds to 500 g of onion ). There were no differences in sex, age, body mass index (BMI )and educational levels between groups before treatment. After 8 weeks of onion extract consumption, plasma triglycerides level was significantly decreased in experimental group com-pared to control (p < 0.05 ). Total cholesterol level was tended to decrease in experimental group, but there was no sig-nificant difference of change between control and experimental group. The levels of plasma glucose and LDL-cholesterol were not changed significantly after onion extract consumption. In summary, alcohol extract of onion may have a positive effect on the lipid profiles of hypercholesterolemia patients through decreasing plasma triglyceride concentration.

Physical Development and Dietary Behaviors of Children in Low-Income Families of Seoul Area / 대한지역사회영양학회지

Since the economic crisis in 1997, the number of low income families has increased and the turmoil is likely to affect nutritional and health status of the children in low-income families. The purpose of this study was to investigate dietary behaviors and physical development of low income family children in the Seoul area. The subjects were 44 boys and 56 girls, between the ages of 7 and 12 years, from the beneficiary families of the governmental assistant program and enrolled in after school-care centers. A self-reported questionnaire, including general characteristics and dietary behaviors, was applied to the children and their parents. Skipping meal rate was higher in breakfast than in lunch or dinner, and was less frequent in parents and children families compared to that of the other types of families (p<0.05). Most students are shown that they usually keep the dietary guideline for Korean children. There were significant differences in keeping the dietary guidelines between the parents and children family group and other groups in several items. The results imply that the nutrition education program should be more focused on the families which are not composed of parents and children.
