Background: Cardiovascular health (CVH) in young adulthood is associated with CVD in later life, yet CVH in young adults in the United States falls below ideal levels, with noticeable sex differences. Research on CVH in young adults in Puerto Rico is scarce. This study examined CVH and sex differences in CVH in a large cohort of young adults in Puerto Rico.
Methods and results: Data from 2162 Puerto Rican young adults aged 18 to 29 residing in PR were obtained from the PR-OUTLOOK (Puerto Rico Young Adults' Stress, Contextual, Behavioral, and Cardiometabolic Risk) study (2020-2023). Participants were recruited through various media and community outreach. CVH scores, graded on a 0 (worst) to 100 (best) scale, were derived from survey responses, physical exams, and laboratory assays. Linear regression with the margins postestimation command was used to determine adjusted means (95% CIs) for CVH scores by sex, controlling for age, marital status, education, childhood material deprivation, subjective social status, health insurance, and depressive symptoms. CVH was less than ideal (score<80) in 72.6% of the cohort (70.5% of women, 75.9% of men, P<0.05). Men had a significantly lower adjusted mean overall CVH score than women (70.7 versus 73.0) and lower adjusted mean scores for nicotine exposure (78.3 versus 86.7), non-high-density lipoprotein cholesterol (80.6 versus 86.4), and blood pressure (79.5 versus 92.2). Women had a significantly lower adjusted mean physical activity score compared with men (50.4 versus 59.5).
Conclusions: Less-than-ideal CVH is notable among young adults, with men having worse CVH than women. These identified sex differences warrant further investigation and the design of interventions to enhance and preserve CVH.
