مقایسه مصاحبه انگیزشی با آموزش های استاندارد کاهش وزن بر ارتقاء برنامه تعهد به کاهش وزن در زنان چاق یا دارای اضافه وزن: کارآزمایی بالینی تصادفی شده

Background and purpose: Prevalence of overweight and obesity is significantly increasing which imposes heavy costs on individuals and communities. Motivational interviewing is a client-based and direct approach to elevate intrinsic motivation and changing people’s behavior by exploring and resolving ambiguities. The health benefits of motivational interviewing have been widely acknowledged. Our survey aimed to evaluate the effects of motivational interviewing on promoting adherence for weight loss program in overweight and obese women. Materials and methods: In a randomized clinical trial we recruited 100 overweight and obese women attending a nutrition clinic. The subjects were randomly divided into a control group and intervention group (n=50 per group). Data was collected using a checklist in pre-test, 2 and 6 month follow-up. Data analysis was performed in SPSS (ver. 16) applying independent t-test and Repeated measure ANOVA. Results: The mean weights in the control and intervention groups were 75.9 ± 6.05 and 74.2 ± 6.95, respectively. Women in the intervention group participated more in motivational interviewing sessions (14.2 times vs. 9.6 times). They also completed the checklists for their dietary intake and physical exercise more than the control group (16.1cases vs. 9.8 cases). There was a significant difference in weight loss between the two groups (P<0.001). Conclusion: Motivational interviewing with usual weight loss education was found to have beneficial outcomes.
