SNAP试验表明，两种自我调节干预措施可以防止年轻人的体重增加。基线时的体重和体型问题（WSC）被评估为24个月时体重结局的调节因素。年轻人（n=599）被随机分为自我调节小变化（SC;创建200千卡/天的赤字），自我调节大变化（LC;促进先发制人的体重减轻5-10磅）。自我控制（C）。使用饮食失调评估中的一个项目评估WSC。使用方差分析检查WSC基线水平与24个月内体重变化百分比之间的相关性是否在治疗条件下存在差异。大约22%的参与者报告了高WSC（37%-中度; 41%-低）。WSC和治疗条件相互作用，影响24个月时的体重变化（p=0.03）。高WSC个体在LC中体重增加（高WSC LSM±SE：+.73± 1.19%，中等：−2.74± 0.84%，低：−2.41±0.79%）。SC对WSC高的患者特别有效（高WSC：-2.49 ± 1.16%，中等：-0.60 ± 0.88%，低：-0.71 ± 0.80%）。WSC没有影响对照组参与者的体重变化。高WSC的个体在SC中比LC具有更好的体重控制结果。这些研究结果表明，WSC可用于匹配个人体重增加预防治疗条件。ClinicalTrials.gov，NCT 01183689
The SNAP trial demonstrated that two self-regulatory interventions prevented weight gain in young adults. Weight and shape concern (WSC) at baseline was evaluated as a moderator of weight outcomes at 24-months. Young adults (n=599) were randomized to self-regulation with Small Changes (SC; to create 200 kcal/day deficit), self-regulation with Large Changes (LC; to facilitate pre-emptive weight loss of 5–10 lbs.) or self-guided control (C). WSC was assessed using one item from the Eating Disorder Assessment. Analysis of variance was used to examine whether the association between baseline level of WSC and percent weight change over 24-months differed across treatment conditions. Approximately 22% of participants reported high WSC (37%-moderate; 41%-low). WSC and treatment condition interacted to influence weight change at 24 months (p=0.03). Individuals with high WSC gained weight in LC (high WSC LSM±SE: +.73±1.19%, moderate: −2.74±0.84%, low: −2.41±0.79%). SC was particularly effective for those with high WSC (high WSC: −2.49±1.16%, moderate:−.60±0.88%, low:−.71±.80%). WSC did not impact weight change among control participants. Individuals with high WSC have better weight control outcomes in SC than LC. These findings suggest that WSC may be used to match individuals to weight gain prevention treatment conditions.
