Key result
Higher perceived informational support is linked to a ~10% lower risk of hard CVD events.
Why the study?
Despite the established link between social support and CVD outcomes, few studies have examined racial and ethnic variation in these associations.
Does perceived social support reduce incident hard CVD events and mortality across different racial/ethnic groups in adults without baseline CVD?

Higher perceived informational support is associated with a lower risk of incident hard cardiovascular events over 18 years, a protective effect that is consistent across White, Black, Hispanic/Latino, and Chinese populations.
BACKGROUND: Despite the established link between social support and cardiovascular disease (CVD) outcomes, few studies have examined racial/ethnic variation in these associations. This study utilized data from the Multi-Ethnic Study of Atherosclerosis (MESA) to investigate racial/ethnic differences in perceived social support and in the link between support and incident hard CVD events and mortality. METHOD: Participants (N = 6,814) were 45-84 years of age who identified as White, Black, Hispanic/Latino, or Chinese without known clinical CVD at baseline (2000-2002). Racial/ethnic differences in perceived support (overall, emotional, informational, and instrumental) were tested using multiple regression with adjustments for demographic, socioeconomic, lifestyle/psychosocial, and clinical risk factors, and immigration history. Racial/ethnic differences in the association between perceived support and incident CVD events or mortality were tested using Cox proportional hazards models with progressive adjustments for the same covariates. RESULTS: At baseline, the mean age was 62.15 years (SD = 10.23); 38.5% identified as White, 27.8% as Black, 22.0% as Hispanic/Latino, and 11.8% as Chinese. Black and Hispanic/Latino participants reported higher levels of overall support, emotional support, and informational support than White participants (p's < 0.05). Chinese participants reported less informational support (p = .010) than White participants. Higher informational support was associated with decreased risk for hard CVD events. This association did not differ by race/ethnic group. CONCLUSION: Despite racial/ethnic differences in perceptions of support, perceived informational support was protective against CVD for participants of all racial/ethnic backgrounds.

Naqvi et al. (2025) conducted a cohort in Cardiovascular disease (n=6,814). Informational social support vs. Lower levels of informational support was evaluated on Incident hard cardiovascular disease events (HR 0.90, 95% CI 0.82-0.98). Higher perceived informational support was associated with a decreased risk for incident hard cardiovascular disease events (HR 0.90) regardless of racial or ethnic background.
