摘要

Many overweight and obese individuals are able to lose significant amounts of weight, but the majority regain the weight over a period of time. There is also a significant patient dropout rate in weight control programs, thus not only resulting in wasted medical resources, but also increasing the frustration between the therapist and the patient. This study was aimed at determining the critical factors that lead to differences in long-term weight maintenance. According to The National Weight Control Registry, we defined long-term weight maintenance as the loss of at least 10% of the initial body weight and maintenance of the loss for at least one year. In this study, we enrolled 612 individuals who had a BMI≧25kg/m^2. Each participant was screened with a medical history and physical examination, and administered a questionnaire pertaining to sleep habits, weight loss expectations, dietary habits, whether or not they ate breakfast, and the weekly exercise time. The participants underwent weight reduction by changing their lifestyle, including controlling their diet and encouraging exercise. By the third month of treatment, 298 (48.7%) participants had dropped out. We analyzed the difference between the continuous treatment and attrition groups. Females had a greater tendency to drop from the program than males (51.1% vs. 42.5%), and those with a BMI＜30kg/m^2 (OR=2.09) and a weekly exercise time＜150 minutes (OR=1.67) had higher dropout rates. At the end of treatment, only 52 (8.5%) participants maintained weight loss successfully. We analyzed the difference between the successful long-term weight maintenance and the non-successful groups using logistic regression, which showed that an age below 30 years (OR=3.83) and a weekly exercise time ＞ 150 min (OR=4.56) were related to successful long-term weight maintenance.
