BACKGROUND
Few studies have reported energy balance-related behavior (EBRB) change for peer leaders delivering health promotion programs to younger students in secondary schools. Our study assessed the impact of the Students As LifeStyle Activists (SALSA) program on SALSA peer leaders' EBRBs, and their intentions regarding these behaviors.
METHODS
We used a pre-post study design to assess changes in EBRBs and intentions of Year 10 secondary school students (15-16 year olds) who volunteered to be peer leaders to deliver the SALSA program to Year 8 students (13-14 year olds). This research is part of a larger study conducted during 2014 and 2015 in 23 secondary schools in Sydney, Australia. We used an online questionnaire before and after program participation to assess Year 10 peer leaders' fruit and vegetable intake, daily breakfast eating, sugar sweetened beverage (SSB) intake, moderate-to-vigorous physical activity (MVPA) participation and school-day recreational screen time behaviors and intentions regarding these EBRBs. Generalized estimating equations with a robust variance structure and exchangeable correlation structure were used to estimate the individual-level summary statistics and their 95% CIs, adjusted for clustering. We further assessed the effect of covariates on EBRB changes.
RESULTS
There were significant increases in the proportion of Year 10 peer leaders (n = 415) who reported eating ≥2 serves fruit/day fruit from 54 to 63% (P < 0.01); eating ≥5 serves vegetables/day from 8 to 12% (P < 0.01); and drinking <1 cup/day of SSBs from 56 to 62% (P < 0.01). Change in ≥60 min MVPA participation/day depended on gender (P < 0.01): Boys increased 14% while girls decreased -2%. Changes in eating breakfast daily also depended on gender (P < 0.004): Boys increased 13% while girls decreased -0.4%. The change in peer leaders recreational screen time differed by socio-economic status (P < 0.05): above average communities decreased by -2.9% while below average communities increased 6.0%. Significant shifts were seen in peer leaders' intentions, except MVPA which remained stable.
CONCLUSIONS
The SALSA program had a positive impact on peer leaders' EBRBs, with gender and socio-economic status moderating some outcomes.

背景
很少有研究报告向中学低年级学生开展健康促进项目的同伴领袖的能量平衡相关行为（EBRB）变化情况。我们的研究评估了“学生成为生活方式倡导者”（SALSA）项目对SALSA同伴领袖的EBRB及其这些行为意图的影响。
方法
我们采用前后对照研究设计，评估自愿成为同伴领袖向八年级学生（13 - 14岁）开展SALSA项目的十年级中学生（15 - 16岁）的EBRB和意图变化。本研究是2014年至2015年在澳大利亚悉尼23所中学进行的一项更大规模研究的一部分。我们在项目参与前后使用在线问卷，评估十年级同伴领袖的水果和蔬菜摄入量、每日早餐食用情况、含糖饮料（SSB）摄入量、中度至剧烈身体活动（MVPA）参与情况以及上学日娱乐屏幕时间行为和这些EBRB的意图。使用具有稳健方差结构和可交换相关结构的广义估计方程来估计个体水平的汇总统计数据及其95%置信区间，并对聚类进行调整。我们进一步评估了协变量对EBRB变化的影响。
结果
报告每天食用≥2份水果的十年级同伴领袖（n = 415）比例从54%显著增加到63%（P < 0.01）；每天食用≥5份蔬菜的比例从8%增加到12%（P < 0.01）；每天饮用<1杯SSB的比例从56%增加到62%（P < 0.01）。每天MVPA参与≥60分钟的变化取决于性别（P < 0.01）：男孩增加了14%，而女孩减少了 - 2%。每天吃早餐的变化也取决于性别（P < 0.004）：男孩增加了13%，而女孩减少了 - 0.4%。同伴领袖娱乐屏幕时间的变化因社会经济地位而异（P < 0.05）：高于平均水平的社区减少了 - 2.9%，而低于平均水平的社区增加了6.0%。同伴领袖的意图有显著变化，除了MVPA意图保持稳定。
结论
SALSA项目对同伴领袖的EBRB有积极影响，性别和社会经济地位对一些结果有调节作用。
