However, the populations of overweight and obese adults are still increasing. The purposes of this study were, therefore, to explore the behaviors of overweight and obese adults weight-control and associated factors. A cross-sectional study was conducted using convenience sampling with a structured questionnaire. Two hundred subjects were participated in the Wenshan district and Hsinyi district, Taipei city. The results were summarized as followed: 1. The results indicated that 56 percent of subjects never conduced a weight control behavior. In the recent year, 40.5 percent conducted healthy methods, 27 percent conducted alternative methods. They use a mean number of 2~3 healthy methods and 0~1 alternative methods. Twenty four percent of subjects used both healthy and alternative methods. 2. The ratio of female conducting alternative and both method were higher than male. The propobility of using healthy method is 0.775 times less with BMI score increasing 1 point. Age, marriage and educations were no statistically significant associated with weight reduce behaviors. 3. The perceived of subjects toward the affect of over weight to health, benefits of weight reduce and barriers of weight were between agreement and disagreement. 4. The self-efficacy of subjects was 50 percent on themselves, and 60 percent on dietary and 30 percent on exercise behavior. 5. Social supports were between rare to occasional from subjects’ family members, friends and were between never and rare from health professionals. 6.
