Background and Purpose: The high prevalence of obesity is a major public problem worldwide. Hence, the needs to explore the factors, not only the physiological but psycho-social factors, have been merged. The aim of this study was to explore the factors affecting the efficacy of weight control in young adults. Methods: A questionnaire consists of external and internal environment sub-questionnaires to measure the factors affecting weight control efficacy in young adults. Participants were 300 college students, including 3 domains of professionals (nursing, nutrition, and non-health-related) from the university in southern Taiwan. The self-administered questionnaire was collected successfully for univariate statistical analyses. Results: The major sex of this sample was female (74%; n=222). 212 (70.7%) individuals intended to losing weight recently, yet, 131 (37.7%) of this sample were actually to execute their weight control plan, and 2 majority of methods to lose weight were exercise or exercise with diet (n=92, 31.7%; n=80, 27%, respectively). In actually executing weight control plan prospect, body weight, BMI, and body shape content were major determinants (p= 0.005, t= -2.806; p<0.001, t=-4.935 ; and p<0.001, t= 6.459, respectively). Furthermore, the more positive psycho-social supports, such as positive colleagues relationships ( p=0.036, t=2.108) have the more social support to weight control motivation. And the higher believe of weight control, more attempt of weight loss, and good diet behaviors (p=0.002, t-3.135; p<0.001, t=11.827; and p=0.04, t=3.199, respectively) have more consistency for weight controlling. There was no association between individual professions and intended to losing weight recently, yet, health related professions likelihood to more actually to execute their weight control plan than non-health-related profession. Conclusion: Psycho-social factors of successfully weight control are determined by body shape content, positive colleagues relationships, higher believe of weight control, more attempt of weight loss, and good diet behaviors.
