| Research Abstract |
Since the prevalence of metabolic syndrome is getting increase in Japanese, we conducted to develop an interventional program for obesity based on health education and self-determination from 2000. We adopted the behavioral program to strengthen self-control of diet and exercise based on learning principles. Objectives of the program were to lose 1.0kg of weight and to reduce 10% of metabolic measurement values.
Subjects were 295 residents with Body Mass Index of 25.0±3.0, aged 56.2±8.4 years in Shimane Prefecture, voluntarily participated in the present study in 2000-2005. The rate of drop out from the program for three months was 7.8%. The behavioral intervention induced significant decreases for intakes of energy (-262kcal), and increase for consumption of energy (147kcal) per day for participants. The intervention induced a significant difference in weight-loss (-1.5kg) for participants.
Significant differences of anthropometric parameters were found in BMI (2.4%), waist circumference (2.2%), blood pressure (2.3/3.8%), glucose (1.4%) and lipid profile, such as total cholesterol (3.0), LDL-cholesterol (4.0%), HDL-cholesterol (5.4%), and triglyceride (13.3%) by the intervention. This investigation suggests that nutritional-assessment and risk-communication on promotion of dietary healthy behaviors have an effect on early treatment for metabolic syndrome.
Weight-loss was determinants explaining less than a total of 10% of the variance in triglyceride, total cholesterol, HDL-cholesterol, and glucose for the participants. Future studies of weight-loss for metabolic syndrome should incorporate Asian ethnic factors, such as dietary behaviors and genetic influence.
