Chang and Jung: Effects of Nutrition Education and Exercise Program on Obesity Index and Behavioral Modification in Moderate Obese Women

Abstract

Objectives

The purpose of this study was to investigate the behavioral modification of obese adults who underwent nutritional and physical activity education. Twenty obese females, aged 20–60 years old, with BMIs (Body Mass Index) >30 or body fat (%) >40 were subjected to this study.

Methods

The physical activity education program consisted of doing exercise in a gymnasium together or home exercise. Dietary attitudes and dietary intakes were assessed using weight control, physical activity, and eating habits. The nutrition-exercise educational period was 12 weeks.

Results

After the study period, there was significant improvement in physical activity and eating habits score. Furthermore, there was a significant increase in the dietary intakes of fiber, iron, potassium, vitamin A, vitamin B6, and niacin. Blood pressure, blood glucose, and total cholesterol levels showed a tendency to decrease, but there was no significant difference. BMI, fat mass, abdominal circumference, and visceral fat levels were significantly reduced while muscle mass significantly increased.

Conclusions

This study suggests that behavioral modification by nutrition and physical activity education with feedback has positive effects on dietary intake and anthropometric biomarkers in obese adults. Therefore, lifestyle interventions of this kind could be recommended as a method for obesity management.
