To conduct a cluster randomized controlled trial comparing the Brazilian version of the New Moves program (NMP) versus observation among Brazilian adolescent girls.
Ten schools were randomly allocated to the Brazilian NMP or the observation arm. Study participants included 12-14-year-old girls. Recruitment occurred between February 2014 and March 2015. The NMP included sports, nutritional support, motivational interviews, collective lunch, and parental information materials. Our main outcome was the Body Shape Questionnaire (BSQ). Secondary outcomes included the Rosenberg Self-Esteem Scale and the Unhealthy Weight-Control Behaviors Index, as well as body mass index. Study results were evaluated through generalized estimating equations.
A total of 270 adolescents participated in the study. At baseline, mean age was 13.4 years, and average BMI was 21.4. The intervention did not result in any statistically significant differences between the NMP and the observation arm, including BSQ (predicted means of 64.33 - IC 95% 59.2-69.47 vs. 62.02 - IC 95% 56.63-67.4), respectively) and our secondary outcomes. Adherence was low during the intervention (32.9%) and maintenance (19.1%) phases of the program.
The New Moves program did not lead to significant changes in our measured outcomes. Future studies should investigate whether changes might occur when comprehensive behavioral programs are sustained over longer periods while also being customized to local population characteristics.
比较巴西版新动（NMP）方案与观察在巴西少女中的效果，进行一项群组随机对照试验。
10 所学校被随机分配至巴西 NMP 或观察组。研究对象包括 12-14 岁女孩。招募时间为 2014 年 2 月至 2015 年 3 月。NMP 包括运动、营养支持、动机访谈、集体午餐和家长信息材料。主要结局为体型问卷（BSQ）。次要结局包括罗森伯格自尊量表和非健康体重控制行为指数，以及体重指数。研究结果通过广义估计方程进行评估。
共有 270 名青少年参与研究。基线时，平均年龄为 13.4 岁，平均 BMI 为 21.4。干预并未导致 NMP 与观察组之间出现任何统计学显著差异，包括 BSQ（预测均值为 64.33-95%置信区间 59.2-69.47 与 62.02-95%置信区间 56.63-67.4）和我们的次要结局。干预（32.9%）和维持（19.1%）阶段的依从性均较低。
新动方案未导致我们测量结局的显著变化。未来研究应探讨当综合行为方案在更长时间内持续并针对当地人群特征进行定制时，是否会发生变化。
