Abstract
Background and purpose: Recent studies indicate that changes in the lifestyle with increased physical activity can prevent type 2 diabetes in high-risk subjects. However, many individuals drop out from structured exercise programs even before any health benefits can be seen. The purpose of this study was to investigate the effects of changing exercise behavior on diabetic risk factors.
Methods: A total of 108 subjects (age range from 22 to 70 years old) who have had at least one risk factor of type 2 diabetes were randomized into control or intervention group. Subjects in the control group received general information about the proper diet and exercise, while subjects in the intervention group were interviewed providing an individualized exercise program and follow-ups based on Health Belief Model and Transtheoretical Model to promote their exercise behaviors. All the subjects received assessment of exercise behavior, exercise self-efficacy, physical fitness, diabetic risk factors, and insulin resistance at baseline and three months after.
Result: Significant differences (p < 0.05) between groups were found in the percentage of regular exerciser (control: 18%; intervention: 51%), daily energy expenditure (control: 0.4% decrease; intervention: 0.3% increase), flexibility (control: 1.0% increase; intervention: 8.9% increase), cardiorespiratory endurance (control: 3.9% increase; intervention: 11.2% increase), body mass index (control: 0.3% decrease; intervention: 1.8% decrease) and exercise self-efficacy (control: 12% increase; intervention: 44% increase). No beneficial effects on insulin resistance were noted.
Conclusions: This randomized controlled study demonstrates that 3-month individualized exercise program enhanced by behavior change strategies can decrease body mass index, and improve daily energy expenditure, flexibility, cardiorespiratory endurance, and exercise self-efficacy in persons who had at least one of the diabetic risk factors.
