Black race was associated with increased risk of acquired concentric left ventricular hypertrophy in non-linemen collegiate American-style football athletes (OR: 3.70).
Is black race associated with an increased risk of acquired concentric left ventricular hypertrophy in collegiate American-style football athletes?
Black race is an independent risk factor for acquired concentric left ventricular hypertrophy among collegiate American-style football non-linemen, highlighting racial differences in athletic cardiac remodeling.

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.
