Spillover Benefits: The Impact of Summer Programming on Parental Rules and Routines Associated with Children's Obesogenic Behaviors

暑假对儿童(5-12岁)的肥胖行为产生负面影响(即减少活动， 看屏幕时间增加，饮食摄入不足，睡眠不规律/被打乱)；儿童体重增加3-5倍 比起整个学年的暑期。结构化天数假说假设结构化的 学校营造的环境规范着肥胖行为。在夏季，出现的结构较少， 导致体重加速增加。我们假设儿童肥胖行为的季节性变化可能 部分原因是父母在夏天放松了与肥胖行为相关的规则/惯例。在.期间 暑假父母对规则/例行公事更加宽容，比如允许孩子晚睡和 更频繁地使用屏幕。然而，当孩子参加在预先指定的日期举行的节目时， 有时，像上学一样，父母可能会强制执行促进健康的规则/惯例(例如，提前就寝，限制屏幕)。 因为夏令营的典型运营时间模仿了学校提供的结构，参加 夏令营也可能影响家长促进健康的规则/惯例。这将促进更大的 夏季家长健康促进规则/常规的一致性；类似于夏季期间的规则/常规 学年。我们假设参加夏令营会影响家长的健康促进 规则/常规在没有正式的育儿行为干预的情况下会导致更健康的行为 孩子们在家里。这种溢出效应-夏令营影响了家长在 家庭--可能对夏季的肥胖干预有重要影响。这位F32博士后 奖学金申请将利用来自随机临床试验的数据(NIDDK R01DK120490，PI Beets) 招募280名来自低收入家庭的小学儿童，其中一半随机获得免费服务 到为期8周的社区夏令营。我们将定量和定性地审查 提供夏令营准入对父母与睡眠、屏幕时间、 和节食。此外，我们将客观地研究家长健康促进规则/惯例对 测量肥胖行为和儿童zBMI。主要目的是评估进入夏季的影响 与对照组相比，从学校到夏天家长健康促进规则/惯例的变化日营 没有获得免费夏令营的团体。第二个目标是评估父母健康的影响- 推广关于改变儿童肥胖行为和体重(ZBMI)的规则/惯例 夏天。最终目标是描述父母对他们如何/为什么保持/改变健康促进的看法 暑假期间的规则/惯例。这项研究具有重要意义，因为有必要了解这种机制 孩子们的肥胖行为会在夏天发生变化。这项研究将为未来的暑期儿童提供信息 肥胖症预防计划。这项研究具有创新性，因为它是最早评估 参加夏令营，了解家长在随机对照试验中促进健康的规则/常规。

Summer vacation exerts a negative effect on children’s (5-12yrs) obesogenic behaviors (i.e., reduced activity, increased screen time, poor diet intake, shifted/disrupted sleep); children gain 3-5 times the amount of weight during the summer compared to the entire school year. The structured days hypothesis posits the structured environment created by school regulates obesogenic behaviors. During summer, less structure is present, leading to accelerated weight gain. We hypothesize seasonal changes in children’s obesogenic behaviors may be due in part to parents relaxing rules/routines related to obesogenic behaviors during the summer. During summer vacation parents are more lenient with rules/routines, such as allowing children to go to bed later and use screens more frequently. However, when a child attends a program that occurs at pre-specified days and times, like school, parents may enforce health-promoting rules/routines (e.g., earlier bedtime, limits on screens). Because the typical operating hours of summer day camps mimic the structure provided by school, attending summer day camp may also influence parent health-promoting rules/routines. This would promote greater consistency of parent health-promoting rules/routines during the summer; similar to rules/routines during the school year. We hypothesize that attending summer day camp will influence parent health-promoting rules/routines in the absence of a formal parenting behavior intervention and lead to more healthful behaviors of children at home. This spillover effect – summer day camp influences parent health-promoting rules/routines at home – can have important implications for obesity interventions during the summer. This F32 Post-Doctoral fellowship application will leverage data from a randomized clinical trial (NIDDK R01DK120490, PI Beets) enrolling 280 elementary-age children from low-income households with half randomized to receive free access to 8-weeks of community-operated summer day camp. We will quantitatively and qualitatively examine the impact of providing access to summer day camp on parent rules/routines associated with sleep, screen time, and diet. Further, we will examine the influence of parent health-promoting rules/routines on objectively measured obesogenic behaviors and child zBMI. The primary aim is to evaluate the impact of access to summer day camp on changes in parent health-promoting rules/routines from school to summer compared to a control group who do not receive free summer day camp. The secondary aim is to evaluate the impact of parent health- promoting rules/routines on changes in child obesogenic behaviors and weight (zBMI) from the school year to summer. The final aim is to describe parent perceptions of how/why they maintain/change health-promoting rules/routines during the summer. This study is significant because it is necessary to understand the mechanisms by which child obesogenic behaviors shift during the summer. This study will inform future summer childhood obesity prevention programs. This study is innovative because it is among the first to evaluate the impact of summer day camp access on parent health-promoting rules/routines within an RCT.
