This study assessed the effects of the "Jump-in" whole-school intervention in Amsterdam, the Netherlands, on children's weight development by comparing children exposed to the intervention and controls from 3 other large Dutch cities. Jump-in is a comprehensive intervention that aims to stimulate healthy nutrition and physical activity in children at primary schools in Amsterdam. In addition, the relationship between the intervention's implementation degree and its effectiveness was studied.
Demographic and anthropometric data, collected by youth health care professionals via routine health checks at T0 (2014) and T1 (2019), were used to analyze possible intervention effects by comparing the weight development of children exposed to the Jump-in intervention versus unexposed controls. Implementation logs from health promotion professionals were used to determine intervention effects per implementation degree. Multilevel regression analyses were used for all analyses.
In total, 4299 children were included mean age ± 5.5 years (T0), 10.6 years (T1), and ≈50% boys/girls at both times. Receiving the fully implemented intervention resulted in a decline in standardized body-mass index (zBMI) compared to the controls (-0.23, confidence interval [CI] -0.33, -0.13). It also led to higher odds to move into a healthier weight category over time (odds ratio [OR] 1.36, CI 1.06, 1.74), yet no statistically significant shift towards a healthy weight was found.
Relative to the controls, children exposed to the intervention showed positive zBMI developments, with stronger effects when the implementation degree was higher. Despite positive results, creating more impact might require the further integration of school-based programs into whole-systems approaches that include other energy-balance behaviors.
本研究通过比较阿姆斯特丹、荷兰与其他 3 个荷兰大城市的暴露于干预组和对照组的儿童，评估了“Jump-in”全校干预对儿童体重发展的影响。Jump-in 是一项旨在刺激阿姆斯特丹小学儿童健康营养和身体活动的综合干预措施。此外，还研究了干预实施程度与其效果之间的关系。
通过青年保健专业人员在 T0（2014 年）和 T1（2019 年）的常规健康检查收集人口统计学和人体测量数据，通过比较暴露于 Jump-in 干预的儿童与未暴露于对照组的儿童的体重发展情况，来分析可能的干预效果。使用健康促进专业人员的实施日志来确定每个实施程度的干预效果。对所有分析均使用多水平回归分析。
共纳入 4299 名儿童，平均年龄为 5.5±5.5 岁（T0）、10.6 岁（T1），且两次均为约 50%的男孩/女孩。与对照组相比，完全实施干预后，标准化体重指数（zBMI）下降（-0.23，置信区间 [CI] -0.33，-0.13）。随着时间的推移，进入更健康体重类别的几率也更高（优势比 [OR] 1.36，CI 1.06，1.74），但未发现健康体重的统计学显著变化。
与对照组相比，暴露于干预的儿童的 zBMI 发展呈正相关，且实施程度越高，效果越强。尽管取得了积极的结果，但要想产生更大的影响，可能需要进一步将基于学校的方案纳入包括其他能量平衡行为的全系统方法。
