One hundred seventy-seven men and women who had participated in an 18-month trial of behavioral interventions involving food provision and financial incentives were examined 12 months later. Food provision, but not financial incentives, led to better weight loss than standard behavioral treatment during the 18-month trial, but over 12 additional months of no-treatment follow-up, all treated groups gained weight, maintained only slightly better weight losses than a no-treatment control group, and did not differ from each other. Weight loss success during both active treatment and maintenance was associated with increase in exercise, decrease in percentage of energy from fat, increase in nutrition knowledge, and decrease in perceived barriers to adherence. Obesity treatment research should focus on developing better ways to maintain changes in the diet and exercise behaviors needed for sustained weight loss.
177名参与了一项为期18个月、涉及食物供应和经济激励的行为干预试验的男性和女性，在12个月后接受了检查。在18个月的试验中，食物供应而非经济激励导致的体重减轻效果优于标准行为治疗，但在另外12个月的无治疗随访期间，所有治疗组体重均增加，仅比无治疗对照组略好地维持了体重减轻，且彼此之间无差异。积极治疗和维持期间的体重减轻成功与运动增加、脂肪能量百分比降低、营养知识增加以及感知到的依从障碍减少有关。肥胖治疗研究应专注于开发更好的方法来维持持续体重减轻所需的饮食和运动行为变化。
