This study aimed to describe the prevalence and sociodemographic characteristics of U.S. adolescents who engage in frequent muscle-building exercise. Data from the 2019 National Youth Risk Behavior Survey (N = 8474) were analyzed. Frequent muscle-building exercise in the past week (≥ 5 days and 7 days) were assessed. Multivariable logistic analyses were conducted separately by sex to obtain adjusted odds ratios and 95% confidence intervals for the association between key sociodemographic characteristics and muscle-building exercise. Nearly one in five (17.9%) boys, compared to 7.7% of girls, reported seven days of muscle-building exercise in the past week. Patterns of sociodemographic characteristics were associated with seven days of muscle-building exercise in the past week, including weight gain attempts among boys and Hispanic/Latina identity among girls. High engagement in muscle-building exercise is common among adolescents, particularly boys, and varied by sociodemographic characteristics, indicating a need for research to further describe engagement in muscle-building exercise among adolescents.

青少年中度和高度参与增肌运动的患病率和社会人口学特征



本研究旨在描述经常进行肌肉锻炼的美国青少年的患病率和社会人口特征。对 2019 年全国青少年危险行为调查 (N = 8474) 的数据进行了分析。评估过去一周(≥ 5 天和 7 天)频繁的增肌运动。按性别分别进行多变量逻辑分析,以获得关键社会人口统计学特征与肌肉锻炼之间关联的调整优势比和 95% 置信区间。近五分之一 (17.9%) 的男孩表示在过去一周进行了 7 天的肌肉锻炼运动,而女孩的这一比例为 7.7%。社会人口统计特征模式与过去一周的 7 天肌肉锻炼锻炼相关,包括男孩的体重增加尝试和女孩的西班牙/拉丁裔身份。青少年(尤其是男孩)高度参与肌肉锻炼运动很常见,并且因社会人口特征而异,表明需要进行研究以进一步描述青少年对肌肉锻炼运动的参与程度。
