Childhood obesity prevention efforts are needed in the United States, especially for families with low income. The purpose of this study is to determine whether HomeStyles-2, a nutrition education and childhood obesity prevention program for families with children in middle childhood (ages 6 to 11 years), motivates parents to re-shape their home environments and weight-related lifestyle practices to be more supportive of meeting national nutrition and physical activity recommendations and weight status of their children more so than those in the control condition.
A research-practice partnership with Florida's Supplemental Nutrition Assistance Program-Education (SNAP-Ed) program was formed to conduct a cluster randomized trial to evaluate the HomeStyles-2 intervention. SNAP-Ed-eligible individuals who are parents/caregivers of children aged 6-11 living in the study catchment area will be invited to enroll in the study and participate in a six-lesson series using the HomeStyles-2 program or an attention control program. The primary outcome measures related to parent weight-related behaviors will be assessed on the individual level. Linear mixed models with a hierarchical design will be used to assess outcomes of interest.
This study has the potential to demonstrate the effectiveness of a new curriculum implemented in a federal nutrition education program. Because of the COVID-19 pandemic, adjustments were made to the intervention design to allow for virtual delivery of the intervention through SNAP-Ed. This unanticipated change will offer much-needed research on the effectiveness of virtual nutrition education, which may help to expand SNAP-Ed's reach across the country.

美国需要开展儿童肥胖预防工作，尤其是针对低收入家庭。本研究旨在确定 HomeStyles-2 是否能够激励家长重塑家庭环境和与体重相关的生活方式实践，使其更有利于满足国家营养和身体活动建议，并更有利于改善儿童的体重状况，这比控制条件下的效果更好。
与佛罗里达州补充营养援助计划教育（SNAP-Ed）项目建立了研究-实践伙伴关系，以开展一项群组随机试验来评估 HomeStyles-2 干预措施。符合 SNAP-Ed 条件的个体，即居住在研究范围内的 6-11 岁儿童的父母/照顾者，将被邀请参加研究，并参与使用 HomeStyles-2 计划或注意力控制计划的六节系列课程。将在个体层面评估与家长体重相关行为的主要结局指标。将使用具有分层设计的线性混合模型来评估感兴趣的结局。
本研究有可能展示在联邦营养教育计划中实施的新课程的有效性。由于 COVID-19 大流行，对干预设计进行了调整，允许通过 SNAP-Ed 进行虚拟干预。这种意外的变化将提供急需的关于虚拟营养教育有效性的研究，这可能有助于扩大 SNAP-Ed 在全国的覆盖范围。
