Effects of Nutritional Education and Exercise Intervention on Improvement of Diet Intakes and Metabolic Risk Factors in Obese Middle Aged Women
Abstract
The purpose of this study was to evaluate a exercise combined with nutritional education for improving metabolic risk factor and dietary intakes in obese middle aged women. 35 obese (body mass index of at least ≥25 kg/m2 or %body fat ≥30%) middle aged women were recruited from public health center. For intervention participants, their height, weight, percentage of body fat, waist circumference, blood pressure, lipid profiles, insulin resistance index, and nutrition intakes were measured at before and after post the intervention. And change of the total energy intakes per week was measured during intervention. The subjects underwent a 12 weeks educational program including nutritional education one day per week and, aerobic exercise 3 days per week (walking). After 12 weeks exercise program combined with nutritional education, body weight (p=0.002), percentage of body fat (p<0.001), BMI (p<0.001), waist circumference (p<0.001), WHR (p=0.004), TC (p=0.004), AI (p=0.006), DBP (p=0.010), MAP (p=0.013), glucose (p=0.018), insulin (p=0.003), HOMA-IR (p<0.001) were significantly decreased and cardiorespiratory fitness was significantly (p<0.001) increased. And energy intake was significantly (p<0.001) decreased and nutritional intake and intake-style were improved through 12 weeks exercise program combined with nutritional education.
Key Words: exercise, nutritional education, middle aged women, obesity, metabolic risk factor
