IDEAL CARDIOVASCULAR HEALTH AMONG RECREATIONAL ROAD RUNNERS PARTICIPATING IN 5 KM, 10 KM, AND HALF-MARATHON: A CROSS-SECTIONAL STUDY
cardiovascular disease, physical activity, running, marathon
Background: Ideal cardiovascular health (ICH) includes four behavioral (smoking, physical activity, body mass index, diet) and three biological (blood pressure, cholesterol, glucose) metrics. While leisure-time running is associated with significant cardiovascular benefits, limited evidence exists on the cardiovascular health (CVH) profile of recreational runners participating in road race events.
Objective: To assess the CVH profile of recreational runners who participated in a major road race event in Brazil, and to explore associated sociodemographic and health-related factors.
Methods: Cross-sectional analysis of self-reported data from adult recreational runners participating in 5 km, 10 km, and half-marathon races in a Brazilian road race event. CVH metrics were categorized as ideal or not, and overall CVH scores were classified as “ideal” (≥5 metrics), “intermediate” (3-4), or “poor” (≤2). Associations with sociodemographic (age, sex, income, education) and health-related (self-rated health and time since last medical check-up) factors were examined using chi-square tests and multivariable Poisson regression models.
Results: A total of 520 runners were included in the final analysis (64.2% between 18-44 years; 41.2% females; 5 km: n = 118; 10 km: n = 167; half-marathon: n = 235), with 74.4% having an “ideal” CVH profile, 24.1% “intermediate”, and 1.6% “poor”. Only 7.7% met all four behavioral metrics, while 70% achieved all three biological metrics. Non-smoking, physical activity, and normal blood pressure, cholesterol, and glucose had the highest prevalence (81.1-99.0%), whereas ideal body mass index and diet were less common (50.6% and 13.5%). The prevalence of ideal CVH scores varied by age, sex, income, education, self-rated health, and time since last medical check-up, but not by race distance (5 km, 10 km, and half-marathon). In the mutually adjusted models, higher income was associated with better overall and behavioral CVH metrics; younger age and better self-rated health were linked to favorable biological metrics.
Conclusion: Overall, recreational runners who participated in a major road race event in Brazil exhibited a favorable CVH profile based on the ICH construct. However, only ~50% and ~15% of participants had ideal body mass index and diet, respectively. In addition, disparities across sociodemographic subgroups underscore the need for targeted strategies to identify recreational runners at higher cardiovascular risk.
