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.
