研究超重的社会网络成员和肥胖的规范性影响是否与肥胖治疗期间的体重减轻结果相关。行为减肥试验的参与者（N=214）报告了（a）其社交网络中各个成员的体重状况和（B）其社交网络中致肥胖规范影响的水平。在治疗前后客观评估体重。在基线时，伴侣和最好的朋友超重的参与者以及有更多孩子和亲戚超重的参与者的BMI较高（p <0.03）。然而，肥胖的社会规范与基线BMI无关。在治疗期间，参与者平均减掉了初始体重的4.4%，社会影响因素与减肥结果呈负相关。有更多的普通朋友在基线时超重，并且是具有更强的不健康饮食社会规范的社交网络的一部分，预测减肥效果较差（p <0.023）。其余的社会影响因素和社会影响的变化与治疗结果无关。尽管体重状况可能在社交网络中“聚集”，但只有普通朋友的体重状况和不健康饮食的规范影响与肥胖治疗结果相关。
To examine whether overweight social network members and normative influence for obesity are associated with weight loss outcomes during obesity treatment. Participants (N=214) in a behavioral weight loss trial reported (a) the weight status of various members of their social network and (b) level of obesogenic normative influence within their social network. Weight was objectively assessed before and after treatment. At baseline, participants with partners and best friends who were overweight and those with more children and relatives who were overweight had higher BMIs (p’s<.03). However, social norms for obesity were not associated with baseline BMI. During treatment, participants lost an average of 4.4% of initial body weight, and social influence factors were adversely associated with weight loss outcomes. Having more casual friends who were overweight at baseline and being part of a social network with stronger social norms for unhealthy eating predicted poorer weight losses (p’s<.023). Remaining social influence factors and changes in social influence were not associated with treatment outcomes. Whereas weight status may “cluster” in social networks, only weight status of casual friends and normative influence for unhealthy eating were associated with obesity treatment outcomes.
