This study was performed to develop a tailored multi-disciplinary obesity management program, as well as an obesity assessment sheet identified the general characteristics and psychological and environmental factors related to weight loss success for obese premenopausal women participating in obesity management programs performed at weight reduction health centers. The results are as follows. The primary general characteristics related to successful weight reduction in the obesity management programs were education level, occupational status, reason for obesity onset, aids used in weight control, basis of frequency, and reason for weight reduction. The initial psychological factors related to successful weight reduction were less stress and disordered eating. The initial environmental factors included an expression of ones opinion and the eating environment. Animal protein and animal fat consumption were significantly less in the unsuccessful group than in those who were unsuccessful at weight loss. The consumption of crude fiber was significantly greater in the successful group than in the unsuccessful group. Psychological factors such as stress, depression, and disordered eating, and the environmental factor of eating environment were significantly better in the successful group than in the unsuccessful group. In conclusion, we have found evidence to suggest what is required in determining the types of programs most suitable for obese women prior to starting an obesity management program.
