Objective This study set out to examine the role of parenting practices in protecting or exacerbating the negative effects of parent and adolescent stress on adolescent body mass index (BMI) over time. Separate longitudinal models were conducted to evaluate how parenting practices interacted with parental perceived stress and adolescent perceived stress in predicting adolescent BMI. Methods Baseline data were collected from 148 African American adolescents (Mage = 12.93, SD = 1.75; Mz-BMI = 0.78, SD = 0.50; MBMI%-ile = 96.7, SD = 3.90) and their caregivers (Mage = 44.45, SD = 8.65; MBMI = 37.63, SD = 8.21) enrolled in the Families Improving Together for Weight Loss trial. Adolescents self-reported their perceptions of caregiver parenting style and feeding practices. Both caregivers and adolescents self-reported their perceptions of chronic stress. BMI for parents and adolescents was assessed objectively at baseline and 16 weeks post-intervention. Results Hierarchical regression models predicting adolescent BMI z-score (z-BMI) indicated a significant interaction between parental perceived stress and parental pressure to eat. Simple slopes analyses demonstrated that for those parents that exhibit higher pressure to eat, parent stress was positively associated with adolescent z-BMI. Conclusions These findings provide preliminary support suggesting that certain parenting practices interact with chronic stress on adolescent weight-related outcomes and that future interventions may consider integrating these factors.

养育和感知压力对非裔美国青少年 BMI 的影响

目的 本研究旨在探讨育儿实践在保护或加剧父母和青少年压力对青少年体重指数 (BMI) 的负面影响方面的作用。进行了单独的纵向模型来评估育儿实践如何与父母感知压力和青少年感知压力相互作用，从而预测青少年 BMI。方法 从 148 名非裔美国青少年（Mage = 12.93，SD = 1.75；Mz-BMI = 0.78，SD = 0.50；MBMI%-ile = 96.7，SD = 3.90）及其照顾者（Mage = 44.45，SD = 8.65；MBMI = 37.63，SD = 8.21）参加了家庭一起改善减肥试验。青少年自我报告了他们对照顾者养育方式和喂养方式的看法。照顾者和青少年都自我报告了他们对慢性压力的看法。在基线和干预后 16 周客观评估父母和青少年的 BMI。结果 预测青少年 BMI z 分数 (z-BMI) 的分层回归模型表明父母感知压力与父母进食压力之间存在显着的相互作用。简单的斜率分析表明，对于那些表现出较高进食压力的父母，父母压力与青少年 z-BMI 呈正相关。结论 这些研究结果提供了初步支持，表明某些育儿实践与青少年体重相关结果的慢性压力相互作用，并且未来的干预措施可能会考虑整合这些因素。结果 预测青少年 BMI z 分数 (z-BMI) 的分层回归模型表明父母感知压力与父母进食压力之间存在显着的相互作用。简单的斜率分析表明，对于那些表现出较高进食压力的父母，父母压力与青少年 z-BMI 呈正相关。结论 这些研究结果提供了初步支持，表明某些育儿实践与青少年体重相关结果的慢性压力相互作用，并且未来的干预措施可能会考虑整合这些因素。结果 预测青少年 BMI z 分数 (z-BMI) 的分层回归模型表明父母感知压力与父母进食压力之间存在显着的相互作用。简单的斜率分析表明，对于那些表现出较高进食压力的父母，父母压力与青少年 z-BMI 呈正相关。结论 这些研究结果提供了初步支持，表明某些育儿实践与青少年体重相关结果的慢性压力相互作用，并且未来的干预措施可能会考虑整合这些因素。
