背景研究表明，小学生在夏季体重会增加。目前尚不清楚这些发现是否适用于西班牙裔青少年。我们评估了西班牙裔中学生的学校和夏季标准化体重指数（zBMI）变化。方法西班牙裔中学生被随机分配到体重管理计划（N = 230）或控制条件（N = 195）。配对样本 t 检验比较了学年期间与未参加体重管理计划的夏季（例如对照组）的 zBMI 变化分数。我们使用 2 × 2 重复测量方差分析来分别确定正常学生和超重/肥胖学生在整个学校与夏季期间 zBMI 分数的项目组差异。 结果在对照组中，正常体重和超重/肥胖学生的学生 zBMI 变化分数在学年期间有所下降，但在夏季期间有所增加。计划对 zBMI 的影响表明，正常学生和超重/肥胖学生的学年减少，夏季增加。然而，正常体重学生的 zBMI 分数并没有因计划状态而有所不同。与对照组相比，该计划中的超重/肥胖学生在夏季的 zBMI 增加幅度较小。结论 对于所有学生，zBMI 在夏季都有所增加。以学校为基础的体重管理计划可以保护超重/肥胖的学生免受夏季体重增加的潜在影响。
BACKGROUNDResearch shows that elementary students gain weight over the summer. It is unknown if these findings apply to Hispanic adolescents. We evaluated school and summer standardized body mass index (zBMI) changes in Hispanic middle school students.METHODSHispanic middle school students were randomly assigned to a weight management program (N = 230) or control condition (N = 195). Paired sample t‐tests compared zBMI change scores during the school year versus summer when not enrolled in a weight management program (eg, control group). We used 2 × 2 repeated measures analysis of variances to determine program group differences in zBMI scores across school versus summer periods separately for normal and overweight/obese students.RESULTSIn the control group, students' zBMI change scores decreased during the school year, but increased during summer for both normal weight and overweight/obese students. Program effects on zBMI indicated school year decreases and summer increases for both normal and overweight/obese students. However, zBMI scores did not differ by program status for normal weight students. Overweight/obese students in the program compared to the control group increased zBMI to a lesser extent over the summer.CONCLUSIONFor all students, zBMI increased during the summer. A school‐based weight management program protected overweight/obese students against potentially greater summer weight gain.
