背景：研究表明，在美国，与暑假相比，儿童在学校期间的BMI和健康水平更高，但研究有限。这项试验性研究的主要目标是评估儿童在学校不上课的几个月里把时间花在哪里，并了解他们在不同的照料环境中从事的不同类型的活动。这项试点研究的第二个目标是了解儿童在暑期吃什么。方法：在一个经济、种族/民族和语言多元化的美国城市，对57名二年级和三年级学生的父母进行了为期九周的暑期研究。每周一次的电话采访询问了在1)主要照顾者的照顾2)其他人的照顾3)假期4)和露营上花费的时间和活动。活动被归类为久坐、轻度、中度或剧烈(0-3分)。对于每个儿童，计算了平均活动水平，并对在每种护理情况下花费的时间比例进行了加权，得出了加权活动指数。在最后一通电话中，家长们回答了有关他们孩子整个夏天的饮食问题。结果：平均活动指数为1.05+/-0.32，不同性别(p=0.07)、教育程度(p=0.08)和家庭主要语言(p=0.01)之间存在差异。在父母照料中花费更多时间的儿童的平均活动指数较低(Beta=-0.004，p=0.01)，而在夏令营中花费更多时间的儿童的活动指数较高(Beta=0.004，p=0.03)。当按cAMP类型分层时，活跃cAMP的时间百分比也与平均活动指数呈正相关(β=0.005，p=0.001)。在饮食方面，经母亲教育调整后，参加夏令营少于5周的儿童经常/几乎所有时间坐在电视机前吃饭的可能性增加了4倍(OR=4.0，95%CI 1.0~16.2，p<；0.06)。结论：暑期活动和某些饮食行为受到照料情况和社会人口学特征的影响。特别是，在结构化环境中花费更多时间的儿童似乎更活跃。我们认为，这项试点研究是我们了解儿童在夏季月份做什么的重要的第一步。
Background: Research indicates that in the United States, children experience healthier BMI and fitness levels during school vs. summer, but research is limited. The primary goal of this pilot study was to assess where children spend their time during the months that school is not in session and to learn about the different types of activities they engage in within different care settings. A secondary goal of this pilot study was to learn what children eat during the summer months.Methods: A nine-week summer study of 57 parents of second and third grade students was conducted in an economically, racial/ethnically and linguistically diverse US urban city. Weekly telephone interviews queried time and activities spent on/in 1) the main caregiver's care 2) someone else's care 3) vacation 4) and camp. Activities were categorised as sedentary, light, moderate, or vigorous (0-3 scale). For each child, a mean activity level was calculated and weighted for proportion of time spent in each care situation, yielding a weighted activity index. On the last phone call, parents answered questions about their child's diet over the summer. Two post-study focus groups were conducted to help interpret findings from the weekly activity interviews.Results: The mean activity index was 1.05 +/- 0.32 and differed between gender (p = 0.07), education (p = 0.08) and primary language spoken in the household (p = 0.01). Children who spent a greater percentage of time in parent care had on average a lower activity index (beta = -0.004, p = 0.01) while children who spent a greater percentage of time in camp had a higher activity index (beta = 0.004, p = 0.03). When stratified into type of camp, percentage of time spent in active camp was also positively associated with mean activity index (beta = 0.005, p =< 0.001). With regards to diet, after adjusting for maternal education, children who attended less than five weeks of camp were four times more likely to eat their meals in front of the TV often/almost all of the time (OR = 4.0, 95% CI 1.0-16.2, p < 0.06).Conclusions: Summer activities and some dietary behaviours are influenced by situation of care and socio-demographic characteristics. In particular, children who spend a greater proportion of time in structured environments appear to be more active. We believe that this pilot study is an important first step in our understanding of what children do during the summer months.
