Psychosocial Factors That Have an Influence on the Effects of Obesity Improvement Programs

Abstract

Objective: The objective of the present study was to clarify the relationship between factors having an influence on obesity improvement programs and psychosocial factors from a more comprehensive point of view. Methods: We studied a total of 43 subjects with a body mass index (BMI) of 25 kg/m2 or higher who wished to take part in an obesity improvement program and agreed to participate in the study. We conducted an obesity improvement program based on behavior change theories for three months and evaluated physical composition, mental health, social support, stress-coping and the like before intervention and immediately after completion of the program. Results: The average weight showed a significant decrease from 69.0 ± 8.8 kg to 65.7 ± 8.7 kg before and after intervention (p<0.001), respectively. It was also shown that the presence or absence of chronic diseases, social support from a spouse and the decrease of avoidance stress coping were related to weight loss.Conclusion: The findings suggest that it will be further necessary to continue working on the need to enhance awareness about stress with a view to preventing occurrence of rebound after the end of weight loss programs and acquisition coping techniques, apart from the cooperation of attending doctors, strengthening of social support from family and friends and managing stress for the duration of the program.
