Prevalence of Elevated Blood Pressure and Risk Factors for Hypertension in College Athletes.

ABSTRACT

OBJECTIVE: To compare the prevalence and risk factors for hypertension (HTN) in college athletes using the new (≥130/80 mm Hg) versus prior (≥140/90 mm Hg) US hypertension guidelines. DESIGN: Retrospective cohort study. SETTING: Eleven Pacific-12 Conference institutions. PARTICIPANTS: Of the 8602 athletes enrolled in the primary study, 4977 (57.9%) met inclusion criteria. Athletes were included in the study if age <30 and blood pressure (BP), baseline demographics (age, weight, height, sex, and race), and primary sport were available. INDEPENDENT VARIABLES Age, sex, race, height, weight, body mass index, and primary sport. MAIN OUTCOME MEASURES: Elevated BP of ≥130/80 mm Hg and/or ≥140/90 mm Hg. RESULTS: Normal BP (<130/80) was present in 3214 (64.6%) athletes and 1763 (35.4%) had BP ≥ 130/80, including 460 (9.2%) with BP ≥ 140/90. Male athletes had a higher prevalence of BP ≥ 130/80 (46.7% vs 21.5%; P < 0.001) and BP ≥ 140/90 (14.2% vs 3.1%; P < 0.001) compared to female athletes. Independent risk factors from multivariate analyses for BP ≥ 130/80 included older age (odds ratio [OR] = 1.05, 95% confidence interval [CI] 1.00-1.11, P = 0.04), male sex (OR = 1.97, 95% CI 1.65-2.35, P < 0.001), heavier weight (OR = 1.03, 95% CI 1.02-1.03, P < 0.001), and baseball as the primary sport (OR = 1.47, 95% CI 1.14-1.90, P < 0.01). Independent risk factors for BP ≥ 140/90 mm Hg included male sex (OR = 3.54, 95% CI 2.55-4.97, P < 0.001) and heavier weight (OR = 1.03, 95% CI 1.02-1.04, P < 0.001). CONCLUSIONS: In a large, diverse cohort of matriculating college athletes from multiple institutions, over one-third presented with elevated BP ≥ 130/80 mm Hg, which was more common in older male athletes with larger body size and baseball players.
