目的评价带有或不带有积极情绪/自我肯定（PA/SA）成分的小改变行为减肥干预在12个月时的减肥效果。方法：体重指数为25 ~ 50 kg/m2的黑人和西班牙裔成年人（N= 405）选择了10种小改变饮食策略中的一种，并设定了身体活动目标，随机加/不加PA/SA。社区卫生工作者每隔一段时间对参与者进行随访（第1 - 3个月每周一次；第4 - 9个月每两周一次；第10 - 12个月每月一次）。结果12个月时，单独采用小变化方法的受试者体重减轻（1.1%）与小变化PA/SA干预（1.2%）之间没有差异。在治疗期间，9%的参与者至少减轻了他们最初体重的7%。报告间隔生活事件较多的参与者减肥的可能性较低（P< 0.0001）。然而，随机分配到小变化PA/SA干预组的患者体重增加较少（+0.3% vs. 2.3%；P< 0.0001）。结论小变化PA/SA干预与单独小变化方法相比，在体重减轻方面没有显著差异。然而，它确实减少了社会心理压力源对间隔生活事件较多的参与者体重增加的负面影响。
ObjectiveTo evaluate the efficacy of a small change behavioral weight loss intervention with or without a positive affect/self‐affirmation (PA/SA) component on weight loss at 12 months.MethodsBlack and Hispanic adults (N= 405) with body mass index 25‐50 kg/m2selected one of ten small change eating strategies and a physical activity goal, randomly with/without PA/SA. Participants were followed by community health workers at set intervals (weekly in months 1‐3; biweekly in months 4‐9; once monthly in months 10‐12).ResultsThere was no difference in weight loss at 12 months between participants in the small change approach alone (1.1%) versus the small change PA/SA intervention (1.2%). During treatment, 9% of participants lost at least 7% of their initial body weight. Participants who reported more interval life events had a lower likelihood of losing weight (P< 0.0001). However, those randomized to the small change PA/SA intervention gained less weight (+0.3% vs. 2.3% gain;P< 0.0001).ConclusionsThe small change PA/SA intervention did not lead to a significant difference in weight loss in comparison to the small change approach alone. It did, however, decrease the negative impact of psychosocial stressors on weight gain among participants with more interval life events.
