The Role of Predictive Factors in Weight Loss Maintenance in Obese People

In obese people, 5-10% reduction in initial weight can decrease the obesity induced risks. Therefore, it is important to identify the predictive factors effective in weight loss maintenance. The present research was conducted to determine the role of important predictive factors in weight loss maintenance. 

For this purpose, a total of 200 women with obesity, were selected using convenience sampling. After explaining the study aims and obtaining the permission to enter the study, they were asked to complete the research tools, including Multidimensional Self-Body Relationship Questionnaire, Three-Factor Eating Behavior Questionnaire, Treatment Outcome Expectations, Weight Lifestyle Self-Efficacy Questionnaire, Caring Environment Questionnaire, Rosenberg Self-Esteem Scale, Depression, Anxiety, and Stress Scale (DASS-21), Multidimensional Perceived Social Support Scale (MSPSS), and Dichotomous Thinking in Eating Disorders Scale (DTEDS). Data were analyzed using SPSS software and Pearson correlation and step by step regression statistical methods. Significance level was considered to be p < 0.05.

The results of the research showed that variables of weight lifestyle self-efficacy, body image, self-esteem, dichotomous thinking, and perceived social support predict 39.8% of variance of successful long-term weight loss maintenance in the participants.

The psychological and behavioral factors play an important role in successful long-term weight loss maintenance in obese subjects. Consideration of these factors seems necessary in weight loss programs.
