OBJECTIVE Young adults (YAs) are at high risk for weight gain and show high variability in treatment response. Life events and high perceived stress are common in YAs and could drive less favorable outcomes. The goal was to examine whether life events and stress were related to program engagement and weight outcomes in a weight gain prevention trial for YAs. METHOD Secondary analysis from the Study of Novel Approaches to Weight Gain Prevention (SNAP), a randomized clinical trial (N = 599, 18-35 years, BMI 21-30 kg/m²). Both intervention arms received 10 in-person sessions over 4 months, with long-term contact via web and SMS. Participants completed the CARDIA life events survey and Cohen Perceived Stress Scale-4 at 0 and 4 months; weight was objectively measured at 0, 4 months, and 1, 2, 3, and 4 years. RESULTS Participants who experienced more life events prior to study entry had lower session attendance (p < .01) and retention (p < .01), although no differences in weight outcomes were observed (p = .39). Baseline perceived stress followed a similar pattern. Participants who experienced more life events and higher perceived stress during the initial in-person program (0-4 months) appeared to experience less favorable weight outcomes long-term (p = .05 for life events, p = .04 for stress). Very few associations differed by treatment arm. CONCLUSIONS Experiencing more life events and stress was negatively associated with program engagement and may impair long-term weight outcomes for YAs. Future work should consider identifying YAs at highest risk and tailoring interventions to better meet their needs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

体重增加预防试验中年轻人的生活事件和压力。

目标 年轻人 (YAs) 体重增加的风险很高，并且在治疗反应中表现出高度可变性。生活事件和高感知压力在 YA 中很常见，可能会导致不太有利的结果。目标是检查生活事件和压力是否与 YA 体重增加预防试验中的计划参与和体重结果相关。方法 二次分析来自预防体重增加新方法研究 (SNAP)，一项随机临床试验（N = 599，18-35 岁，BMI 21-30 kg/m²）。两个干预组在 4 个月内接受了 10 次面对面会议，并通过网络和短信进行了长期联系。参与者在 0 个月和 4 个月时完成了 CARDIA 生活事件调查和 Cohen Perceived Stress Scale-4；在 0、4 个月和 1、2、3 和 4 岁时客观测量体重。结果 在进入研究之前经历过更多生活事件的参与者的出勤率 (p < .01) 和保留率 (p < .01) 较低，尽管未观察到体重结果存在差异 (p = .39)。基线感知压力遵循类似的模式。在最初的面对面计划（0-4 个月）期间经历更多生活事件和更高感知压力的参与者似乎长期经历不太有利的体重结果（生活事件 p = .05，压力 p = .04）。很少有关联因治疗组而异。结论 经历更多的生活事件和压力与项目参与度呈负相关，并可能损害 YA 的长期体重结果。未来的工作应考虑确定风险最高的青年人并调整干预措施以更好地满足他们的需求。
