Abstract P638: Sex Differences in Cardiovascular Health Among Young Adults in Puerto Rico

Abstract

Background: Emerging evidence supports significant variations in cardiovascular health (CVH), as defined by the American Heart Association (AHA) using “Life’s Simple 7” metrics, among Hispanics in the mainland US by sex and heritage group. Of these, Hispanic men and those of Puerto Rican background are less likely to meet favorable CVH criteria. Yet data on young men and women residing in Puerto Rico, an understudied population with a unique sociocultural context, are scarce. We assessed sex differences in CVH among young adults living in Puerto Rico. Measures: We used PR-OUTLOOK baseline data, collected between September 2020 and September 2022, for this analysis. Participants were between the ages of 18-29 years. CVH was measured using the AHA Life’s Essential 8 (LE8) score, a revised composite metric of physical activity, smoking, diet, sleep, body mass index (BMI), blood pressure, blood glucose, and non-HDL cholesterol. The total score ranges from 0-100, with higher scores indicating better CVH. For this analysis, the measure was modified to exclude diet given the lack of dietary data. Multivariable linear regression models were used to assess sex differences in the overall CVH score and its components. Analyses were adjusted for age, sex, marital status, and childhood material deprivation. Results: The sample included 964 adults - 619 women and 345 men. In adjusted analysis, women had a higher overall CVH score compared to men (β=2.77, 95% CI: 1.10, 4.44). Women also had higher scores for nicotine exposure (β=9.24, 95% CI: 5.18, 13.29), non-HDL cholesterol (β=4.31, 95% CI: 1.11, 7.51), and blood pressure (β=13.22, 95% CI: 10.39, 16.05) but lower for physical activity (β=-9.55, 95% CI: -15.18, -3.91). There were no significant sex differences in scores for sleep health, BMI, and blood glucose. Conclusion: There are sex differences in CVH among young adults in Puerto Rico, with women having overall better CVH. Interventions to improve nicotine exposure, non-HDL cholesterol, and blood pressure in men and participation in physical activity in women are needed to enhance and preserve overall CVH.
