Objective Minority student-athletes have a lower survival rate from sudden cardiac arrest (SCA) than non-minority student-athletes. This study examined the relationship between high school indicators of socioeconomic status (SES) and survival in student-athletes with exercise-related SCA. Methods High school student-athletes in the USA with exercise-related SCA on school campuses were prospectively identified from 1 July 2014 to 30 June 2018 by the National Center for Catastrophic Sports Injury Research. High school indicators of SES included the following: median household and family income, proportion of students on free/reduced lunch and percent minority students. Resuscitation details included witnessed arrest, presence of an athletic trainer, bystander cardiopulmonary resuscitation and use of an on-site automated external defibrillator (AED). The primary outcome was survival to hospital discharge. Differences in survival were analysed using risk ratios (RR) and univariate general log-binomial regression models. Results Of 111 cases identified (mean age 15.8 years, 88% male, 49% white non-Hispanic), 75 (68%) survived. Minority student-athletes had a lower survival rate compared with white non-Hispanic student-athletes (51.1% vs 75.9%; RR 0.67, 95% CI 0.49 to 0.92). A non-significant monotonic increase in survival was observed with increasing median household or family income and with decreasing percent minority students or proportion on free/reduced lunch. The survival rate was 83% if an athletic trainer was on-site at the time of SCA and 85% if an on-site AED was used. Conclusions Minority student-athletes with exercise-related SCA on high school campuses have lower survival rates than white non-Hispanic athletes, but this difference is not fully explained by SES markers of the school. All data relevant to the study are included in the article or uploaded as supplementary information.

美国高中生运动员运动相关心脏骤停的社会经济因素和结果

目的少数民族学生运动员的心脏骤停（SCA）存活率低于非少数民族学生运动员。本研究探讨了高中社会经济地位 (SES) 指标与运动相关 SCA 学生运动员生存率之间的关系。方法 2014 年 7 月 1 日至 2018 年 6 月 30 日期间，美国国家灾难性运动损伤研究中心前瞻性地确定了在校园内患有与运动相关的 SCA 的美国高中生运动员。SES 的高中指标包括：家庭和家庭收入中位数、免费/减价午餐学生比例和少数族裔学生百分比。复苏细节包括目击者逮捕、运动教练在场、旁观者心肺复苏和使用现场自动体外除颤器 (AED)。主要结果是生存到出院。使用风险比 (RR) 和单变量一般对数二项式回归模型分析生存差异。结果 在确定的 111 例病例中（平均年龄 15.8 岁，88% 为男性，49% 为非西班牙裔白人），75 例（68%）存活。与非西班牙裔白人学生运动员相比，少数族裔学生运动员的存活率较低（51.1% 对 75.9%；RR 0.67，95% CI 0.49 至 0.92）。随着家庭或家庭收入中位数的增加以及少数族裔学生的百分比或免费/减少午餐的比例减少，观察到生存率没有显着的单调增加。如果运动教练在 SCA 时在现场，则存活率为 83%，如果使用现场 AED，则存活率为 85%。结论 高中校园运动相关 SCA 的少数学生运动员的存活率低于非西班牙裔白人运动员，但学校的 SES 标记并不能完全解释这种差异。所有与研究相关的数据都包含在文章中或作为补充信息上传。
