家庭环境对与肥胖相关的儿童健康行为的影响尚不清楚。研究家庭体力活动（PA）和食物环境对幼儿相应结果的作用，并评估母亲的教育/工作状况作为调节剂。超重或肥胖的母亲报告了家庭PA和食品环境（可访问性，榜样作用和父母的政策）。结果包括儿童中度活跃PA（MVPA）和久坐时间来自加速度计数据和两个饮食因素（“垃圾”和健康食物摄入量得分）的基础上，母亲报告的食物摄入量的因素分析。线性回归模型评估了家庭环境对结局的净效应（控制儿童人口统计学、研究组、补充时间点、母亲教育/工作状态、儿童体重指数和加速度计佩戴时间（用于PA结局））以及母亲教育/工作状态的调节作用。数据收集于2007-2011年的北卡罗来纳州。父母的政策支持PA增加MVPA时间，并限制获得不健康的食物增加健康的食物摄入量得分。健康饮食行为的角色塑造增加了没有受过大学教育的母亲的孩子的健康食物摄入量得分。在没有受过大学教育和没有工作的母亲的孩子中，限制获得不健康食品和榜样作用降低了“垃圾”食品摄入量分数，而支持家庭用餐的父母政策增加了“垃圾”食品摄入量分数。为了促进MVPA，支持儿童PA的父母政策是必要的。限制获得不健康食品的机会和健康饮食的榜样作用可能会提高儿童食物摄入的质量。
The effects of the home environment on child health behaviors related to obesity are unclear. To examine the role of the home physical activity (PA) and food environment on corresponding outcomes in young children, and assess maternal education/work status as a moderator. Overweight or obese mothers reported on the home PA and food environment (accessibility, role modeling and parental policies). Outcomes included child moderate-vigorous PA (MVPA) and sedentary time derived from accelerometer data and two dietary factors (“junk” and healthy food intake scores) based on factor analysis of mother-reported food intake. Linear regression models assessed the net effect (controlling for child demographics, study arm, supplemental timepoint, maternal education/work status, child body mass index and accelerometer wear-time (for PA outcomes)) of the home environment on the outcomes and moderation by maternal education/work status. Data was collected in North Carolina from 2007–2011. Parental policies supporting PA increased MVPA time, and limiting access to unhealthy foods increased the healthy food intake score. Role modeling of healthy eating behaviors increased the healthy food intake score among children of mothers with no college education. Among children of mothers with no college education and not working, limiting access to unhealthy foods and role modeling reduced “junk” food intake scores while parental policies supporting family meals increased “junk” food intake scores. To promote MVPA, parental policies supporting child PA are warranted. Limited access to unhealthy foods and role modeling of healthy eating may improve the quality of the child’s food intake.
