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.
本研究旨在描述参与频繁肌肉锻炼的美国青少年的流行率和社会人口学特征。对 2019 年全国青年风险行为调查（N=8474）的数据进行了分析。评估了过去一周（≥5 天和 7 天）内频繁的肌肉锻炼情况。按性别分别进行多变量逻辑分析，以获得关键社会人口学特征与肌肉锻炼之间关联的调整后优势比和 95%置信区间。近五分之一（17.9%）的男孩，与女孩的 7.7%相比，报告过去一周有七天进行肌肉锻炼。社会人口学特征的模式与过去一周内进行七天的肌肉锻炼有关，包括男孩中的体重增加尝试和女孩中的西班牙裔/拉丁裔身份。青少年中，尤其是男孩中，高度参与肌肉锻炼很常见，而且因社会人口学特征而异，这表明需要进一步研究来描述青少年的肌肉锻炼参与情况。
