Embedded within children's weight trajectories are complex environmental contexts that influence obesity risk. As such, the normative environment of body mass index (BMI) within schools may influence children's weight trajectories as they age from kindergarten to fifth grade.
I use 5 waves of the ECLS-K-Kindergarten Class 1998-1999 data and a series of multilevel growth models to examine whether attending schools with higher overall BMI influences children's weight status over time.
Results show that, net of child, family, and school sociodemographic characteristics, children who attend schools with higher rates of obesity have increased weight compared to children who attend schools with lower rates of obesity, and this effect increases annually.
Findings indicate that the overall weight status of schools influence child obesity, and further speak to the importance of school-based intervention programs.
儿童体重轨迹中嵌入了复杂的环境背景，这些环境会影响肥胖风险。因此，学校内的体重指数（BMI）的规范环境可能会影响儿童从幼儿园到五年级的体重轨迹。
我使用了 ECLS-K-幼儿园 1998-1999 年数据的 5 个波次和一系列多层次增长模型，来检验在儿童从幼儿园到五年级的成长过程中，就读 BMI 整体较高的学校是否会影响他们的体重状况。
结果表明，在控制了儿童、家庭和学校社会人口统计学特征后，与就读肥胖率较低的学校的儿童相比，就读肥胖率较高学校的儿童体重增加，且这种影响逐年增加。
研究结果表明，学校的整体体重状况会影响儿童肥胖，这进一步说明了以学校为基础的干预计划的重要性。
