This ecological study estimated associations between school-wide attendance and expulsions for student firearm possession using administrative data for Michigan public K-12 schools from 2018-2022 (N=2,866 schools). Between the 2018-19 and 2021-22 school years, 77 Michigan public schools (2.7%) expelled students for firearm possession. In unadjusted models, higher rates of on-track attendance (i.e., the proportion of students who attend ≥90% of school days) were associated with lower odds of the school having an expulsion for student firearm possession (OR=0.96; 95% CI=0.95, 0.97). This association remained after adjusting for student body demographics, school building characteristics, and school rates of student interpersonal violence and discipline (aOR=0.97; 95% CI=0.95, 0.98). Efforts to improve school-wide attendance may offer a primary and universal prevention avenue against student firearm possession.
这项生态学研究利用2018 - 2022年密歇根州公立K - 12学校的行政数据（N = 2866所学校），估计了全校出勤率与学生持有枪支被开除之间的关联。在2018 - 19学年至2021 - 22学年期间，77所密歇根州公立学校（2.7%）因学生持有枪支而开除了学生。在未调整的模型中，较高水平的正常出勤率（即上学天数≥90%的学生比例）与学校因学生持有枪支而进行开除的较低几率相关（OR = 0.96；95% CI = 0.95，0.97）。在对学生群体人口统计学、学校建筑特征以及学生人际暴力和纪律处分率进行调整后，这种关联依然存在（校正后OR = 0.97；95% CI = 0.95，0.98）。提高全校出勤率的努力可能为预防学生持有枪支提供一条主要且通用的途径。
