父母的压力是一个未被充分研究的因素，它可能会损害与孩子的饮食摄入、体育活动和肥胖有关的育儿实践。然而，检验这些相关性的研究一直受到方法学的限制，包括横断面设计、回溯性措施、缺乏应激生物标记物，以及忽视每天发生的瞬时病因过程的倾向。本文描述了Match(母亲和他们的孩子的健康)研究的招募、数据收集和数据分析方案，这是一项使用新型实时数据捕获策略的纵向调查，旨在研究母亲压力与儿童体力活动和饮食摄入量之间的日内关联，以及这些影响如何导致儿童肥胖风险。在Match研究中，200名母亲和她们8至12岁的孩子参加了为期3年的6次半年度评估。在每一波中，母子二人组的衡量标准包括：(A)对自我报告的日常心理社会压力源(如工作、家庭需求)、感觉压力、感知压力、育儿做法、饮食摄入量和带有时间和地点戳的体力活动的实时生态瞬时评估(EMA)；(B)每日唾液皮质醇模式、加速计监测的体力活动和24小时饮食回忆；(C)社会人口、文化、家庭和邻里协变量的回溯性问卷；以及(D)身高、体重和腰围。母体应激对儿童膳食摄入量、体力活动和身体成分可能产生的日内和纵向影响将分别通过多水平模型和潜在生长曲线模型进行检验。这一结果将成为帮助母亲减少压力对与体重相关的育儿实践和儿童肥胖风险的负面影响的干预措施。
Parental stress is an understudied factor that may compromise parenting practices related to children's dietary intake, physical activity, and obesity. However, studies examining these associations have been subject to methodological limitations, including cross-sectional designs, retrospective measures, a lack of stress biomarkers, and the tendency to overlook momentary etiologic processes occurring within each day. This paper describes the recruitment, data collection, and data analytic protocols for the MATCH (Mothers And Their Children's Health) study, a longitudinal investigation using novel real-time data capture strategies to examine within-day associations of maternal stress with children's physical activity and dietary intake, and how these effects contribute to children's obesity risk. In the MATCH study, 200 mothers and their 8 to 12 year-old children are participating in 6 semi-annual assessment waves across 3 years. At each wave, measures for mother-child dyads include: (a) real-time Ecological Momentary Assessment (EMA) of self-reported daily psychosocial stressors (e.g., work at a job, family demands), feeling stressed, perceived stress, parenting practices, dietary intake, and physical activity with time and location stamps; (b) diurnal salivary cortisol patterns, accelerometer-monitored physical activity, and 24-hour dietary recalls; (c) retrospective questionnaires of sociodemographic, cultural, family, and neighborhood covariates; and (d) height, weight, and waist circumference. Putative within-day and longitudinal effects of maternal stress on children's dietary intake, physical activity, and body composition will be tested through multilevel modeling and latent growth curve models, respectively. The results will inform interventions that help mothers reduce the negative effects of stress on weight-related parenting practices and children's obesity risk.
