The home environment is where young children spend most of their time, and is critically important to supporting behaviors that promote health and prevent obesity. However, the home environment and lifestyle patterns remain understudied, and few interventions have investigated parent-led makeovers designed to create home environments that are supportive of optimal child health and healthy child weights.
The aim of the HomeStyles randomized controlled trial (RCT) is to determine whether the Web-based HomeStyles intervention enables and motivates parents to shape the weight-related aspects of their home environments and lifestyle behavioral practices (diet, exercise, and sleep) to be more supportive of their preschool children's optimal health and weight.
A rigorous RCT utilizing an experimental group and an attention control group, receiving a bona fide contemporaneous treatment equal in nonspecific treatment effects and differing only in subject matter content, will test the effect of HomeStyles on a diverse sample of families with preschool children. This intervention is based on social cognitive theory and uses a social ecological framework, and will assess: intrapersonal characteristics (dietary intake, physical activity level, and sleep) of parents and children; family interpersonal or social characteristics related to diet, physical activity, media use, and parental values and self-efficacy for obesity-preventive practices; and home environment food availability, physical activity space and supports in and near the home, and media availability and controls in the home.
Enrollment for this study has been completed and statistical data analyses are currently underway.
This paper describes the HomeStyles intervention with regards to: rationale, the intervention's logic model, sample eligibility criteria and recruitment, experimental group and attention control intervention content, study design, instruments, data management, and planned analyses.
家庭环境是幼儿大部分时间所处的地方，对于支持促进健康和预防肥胖的行为至关重要。然而，家庭环境和生活方式模式仍未得到充分研究，很少有干预措施调查过由家长主导的改造活动，这些活动旨在营造有利于儿童最佳健康和健康体重的家庭环境。
“家庭风格”随机对照试验（RCT）的目的是确定基于网络的“家庭风格”干预措施是否能够促使并激励家长塑造家庭环境中与体重相关的方面以及生活方式行为习惯（饮食、运动和睡眠），使其更有利于学龄前儿童的最佳健康和体重。
一项严格的随机对照试验，采用实验组和注意力控制组，两组接受的真诚同期治疗在非特异性治疗效果方面相同，仅在主题内容上有所不同，将测试“家庭风格”对不同的有学龄前儿童家庭样本的影响。该干预措施基于社会认知理论并采用社会生态框架，将评估：家长和儿童的个人内在特征（饮食摄入量、身体活动水平和睡眠）；与饮食、身体活动、媒体使用以及家长对预防肥胖做法的价值观和自我效能相关的家庭人际或社会特征；以及家庭环境中的食物供应情况、家庭内外的身体活动空间和支持设施，以及家庭中的媒体供应和控制情况。
本研究的招募工作已完成，目前正在进行统计数据分析。
本文从以下方面描述了“家庭风格”干预措施：基本原理、干预措施的逻辑模型、样本入选标准和招募情况、实验组和注意力控制组的干预内容、研究设计、工具、数据管理以及计划的分析。
