This study aimed to determine the association between engagement in muscle-building exercise and weapon carrying and physical fighting among adolescent boys. Cross-sectional data from the 2019 Youth Risk Behavior Survey (U.S.) were analyzed ( = 4120). Muscle-building exercise was assessed based on the number of days reported in the past 7 days, recategorized into four levels of engagement (no engagement [0 days], low engagement [1-2 days], moderate engagement [3-5 days], and high engagement [6-7 days]). Three forms of weapon carrying (general, on school grounds, gun carrying) and two forms of physical fighting (general, on school grounds) were assessed. Five logistic regression analyses with adjusted odds ratios (AOR) and 95% confidence intervals (CI) were used to determine the association between engagement in muscle-building exercise and weapon carrying and physical fighting, while adjusting for relevant demographic and control variables. Over 75% of participants reported engaging in muscle-building exercise. One in five (19.8%) participants reported any general weapon carrying in the past 30 days, 3.3% reported any weapon carrying at school in the past 30 days, 6.5% reported any gun carrying in the past 12 months, 28.0% reported any general physical fighting in the past 12 months, and 10.7% reported any physical fighting at school in the past 12 months. Logistic regressions showed that, compared to no engagement, participants who reported high engagement of muscle-building exercise had higher odds of general weapon carrying (AOR 2.18, 95% CI 1.54-3.07), gun carrying (AOR 2.12, 95% CI 1.23-3.64), and general physical fighting (AOR 2.07, 95% CI 1.53-2.79). These are novel findings that add to a growing literature related to engagement in muscularity-oriented behaviors among males. Prevention and intervention efforts are needed to ensure that adolescent boys engage in muscle-building exercise in ways that are not harmful and to reduce weapon carrying and physical fighting.
这项研究旨在确定青少年男孩参与增肌运动与携带武器和打架斗殴之间的关联。对 2019 年美国青少年风险行为调查（Youth Risk Behavior Survey，YRBS）的横断面数据（n=4120）进行了分析。增肌运动是根据过去 7 天报告的天数来评估的，重新分类为四个参与水平（不参与[0 天]、低参与[1-2 天]、中参与[3-5 天]和高参与[6-7 天]）。携带武器（一般、在学校、携带枪支）和打架斗殴（一般、在学校）的两种形式都进行了评估。使用调整后的比值比（adjusted odds ratio，AOR）和 95%置信区间（95% confidence intervals，CI）进行了五次 logistic 回归分析，以确定参与增肌运动与携带武器和打架斗殴之间的关联，同时调整了相关的人口统计学和控制变量。超过 75%的参与者报告参与了增肌运动。五分之一（19.8%）的参与者报告在过去 30 天内有任何一般形式的携带武器，3.3%的人报告在过去 30 天内在学校携带过武器，6.5%的人报告在过去 12 个月内携带过枪支，28.0%的人报告在过去 12 个月内有任何一般形式的打架斗殴，10.7%的人报告在过去 12 个月内在学校有任何形式的打架斗殴。logistic 回归显示，与不参与相比，报告高参与增肌运动的参与者更有可能携带一般武器（AOR 2.18，95%CI 1.54-3.07）、枪支（AOR 2.12，95%CI 1.23-3.64）和一般打架斗殴（AOR 2.07，95%CI 1.53-2.79）。这些新发现增加了与男性参与肌肉发达行为相关的不断增长的文献。需要采取预防和干预措施，确保青少年男孩以无害的方式参与增肌运动，并减少携带武器和打架斗殴的行为。
