Objectives American-style football (ASF) athletes are at risk for the development of concentric left ventricular hypertrophy (C-LVH), an established cardiovascular risk factor in the general population. We sought to address whether black race is associated with acquired C-LVH in collegiate ASF athletes. Methods Collegiate ASF athletes from two National Collegiate Athletic Association Division-I programmes were recruited as freshmen between 2014 and 2019 and analysed over 3 years. Demographics (neighbourhood family income) and repeated clinical characteristics and echocardiography were recorded longitudinally at multiple timepoints. A mixed-modelling approach was performed to evaluate acquired C-LVH in black versus white athletes controlling for playing position (linemen (LM) and non-linemen (NLM)), family income, body weight and blood pressure. Results At baseline, black athletes (N=124) were more often NLM (72% vs 54%, p=0.005) and had lower median neighbourhood family income ($54 119 vs $63 146, p=0.006) compared with white athletes (N=125). While both black and white LM demonstrated similar increases in C-LVH over time, among NLM acquired C-LVH was more common in black versus white athletes (postseason year-1: N=14/89 (16%) vs N=2/68 (3%); postseason year-2: N=9/50 (18%) vs N=2/32 (6%); postseason year-3: N=8/33 (24%) vs N=1/13 (8%), p=0.005 change over time). In stratified models, black race was associated with acquired C-LVH in NLM (OR: 3.70, 95% CI 1.12 to 12.21, p=0.03) and LM was associated with acquired C-LVH in white athletes (OR: 3.40, 95% CI 1.03 to 11.27, p=0.048). Conclusions Independent of family income and changes in weight and blood pressure, black race was associated with acquired C-LVH among collegiate ASF NLM and LM was associated with acquired C-LVH in white athletes.

美式足球运动员种族与适应不良的向心性左心室肥大的关系

目标 美式足球 (ASF) 运动员有发生同心左心室肥厚 (C-LVH) 的风险，这是一般人群中已确定的心血管危险因素。我们试图解决黑人种族是否与大学 ASF 运动员获得的 C-LVH 相关。方法 在 2014 年至 2019 年期间，招募来自两个全国大学体育协会一级项目的大学 ASF 运动员作为新生，并在 3 年内进行分析。在多个时间点纵向记录人口统计学（邻里家庭收入）和重复的临床特征和超声心动图。采用混合建模方法来评估黑人和白人运动员的获得性 C-LVH，控制比赛位置（前锋 (LM) 和非前锋 (NLM)）、家庭收入、体重和血压。结果 在基线时，与白人运动员（N =125)。虽然随着时间的推移，黑色和白色 LM 都表现出类似的 C-LVH 增加，但在 NLM 中，获得性 C-LVH 在黑人和白人运动员中更为常见（季后赛第一年：N=14/89 (16%) vs N=2/ 68 (3%)；季后赛第二年：N=9/50 (18%) vs N=2/32 (6%)；季后赛第三年：N=8/33 (24%) vs N=1/ 13 (8%), p=0.005 随时间变化）。在分层模型中，黑人种族与 NLM 中获得性 C-LVH 相关（OR：3.70，95% CI 1.12 至 12.21，p=0.03），LM 与白人运动员获得性 C-LVH 相关（OR：3.40，95% CI 1.03 至 11.27，p = 0.048）。结论 独立于家庭收入以及体重和血压的变化，黑人种族与大学 ASF NLM 中获得性 C-LVH 相关，LM 与白人运动员获得性 C-LVH 相关。没有可用的数据。没有可用的数据。这些数据是去识别的参与者数据，不可供公众使用。
