概括
提供免费的夏日营地 (SDCs) 显著降低了低收入儿童的BMI z-分数的增长. 增加的SDC出席率与zBMI的更大降低相关,突出了可访问的夏季课程的重要性.
科学领域:
- 儿科公共卫生 儿科公共卫生
- 预防肥胖 预防肥胖
- 社区干预 社区干预
背景情况:
- 儿童,特别是来自低收入家庭的儿童,在夏季经历了身体质量指数 (BMI) 的加速增长,这是由于缺乏基于学校的健康结构.
- 夏日营地 (SDC) 提供促进健康的结构,但通常是以收费为基础的,为处于风险的人群创造了财务障碍.
- 缺乏结构化的夏季活动有助于儿童不健康的体重增加.
研究的目的:
- 确定是否提供免费进入现有社区夏日营地 (SDC) 缓解了小学年龄儿童加速的BMI z-score (zBMI) 增加.
- 调查SDC免费访问对夏季儿童zBMI变化的影响.
- 探索SDC出席率和zBMI变化之间的剂量反应关系.
主要方法:
- 一项随机临床试验,涉及2021-2023年夏季在美国东南部低收入家庭的422名小学龄儿童.
- 参与者被随机分配到一个免费的SDC计划或对照组 (像往常一样夏天).
- 测量的主要结果是zBMI从5月到8月变化的群体间差异;二次分析检查了出席剂量-反应.
主要成果:
- 干预组 (无SDC) 的zBMI变化明显减少 (-0.048) 与对照组 (0.046) 相比,两组之间的差异为-0.094.
- 剂量反应分析显示,每周每增加一天的SDC出席与zBMI的减少有关.
- 与没有参加任何夏季节目的儿童相比,每周每天参加SDC的儿童的zBMI下降幅度最大.
结论:
- 免费访问社区SDC是一个有效的策略,以减轻不健康的zBMI在夏季低收入家庭儿童的收益.
- 这些发现强调了可访问,结构化的夏季计划对预防儿童肥胖的公共卫生相关性.
- 建议进行进一步的研究,以在不同地区复制发现,并确定最佳的计划持续时间和强度.

02:01Group Design
8.9K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

01:13Randomized Experiments
6.7K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

01:52Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
