目的：肌肉强化活动（MSE，例如俯卧撑，仰卧起坐，使用重量机器）与青少年的多重健康益处有关，并且是全球儿童和青少年（5-17岁）身体活动指南的一部分。然而，在青年健康监测中很少评估MSE。这项研究描述了纵向趋势和预测MSE之间的一个队列的加拿大青年。设计：纵向。研究方法：数据来自一组3366名参与三波COMPASS的青少年，这是一项针对加拿大中学生的纵向研究[Wave 1（T1）2015/16，Wave 2（T2）2016/17，Wave 3（T3）2018/19]。计算每个波符合MSE指南（>_3天/周）的样本的患病率。多变量logistic回归评估了各波（T1、T2和T3）符合MSE指南的几率，包括社会人口统计学/生活方式特征（例如，性别、种族、地区、体重指数和有氧体力活动）。结果：对于总样本，MSE指南依从性在每个研究阶段均显著下降（T1 = 57.0%; T2 = 52.0%; T3 = 48.5%; p
Objectives: Muscle-strengthening activity (MSE e.g. push-ups, sit-ups, use of weight machines) is linked to mul-tiple health benefits for youth, and is part of the global physical activity guidelines for children and adolescents (5-17 years). However, MSE is rarely assessed in youth health surveillance. This study describes the longitudinal trends and predictors of MSE among a cohort of Canadian youths. Design: Longitudinal. Methods: Data were drawn from a cohort of 3366 youths who participated in three waves of COMPASS, a longi-tudinal study of secondary school students across Canada [Wave 1 (T1) 2015/16, Wave 2 (T2) 2016/17, Wave 3 (T3) 2018/19]. The prevalence of the sample meeting the MSE guideline (>_3 days/week) was calculated for each wave. A multivariable logistic regression assessed the odds of meeting the MSE guideline for each wave (T1 and T2 and T3) across sociodemographic/lifestyle characteristics (e.g. sex, race, regionally, Body Mass Index, and aer-obic physical activity). Results: For the total sample, MSE guideline adherence significantly declined across each study wave (T1 = 57.0%; T2 = 52.0%; T3 = 48.5%; p
