Maternal experiences of ethnic discrimination and child cardiometabolic outcomes in the Study of Latino (SOL) Youth

Abstract Purpose Limited research has examined maternal experiences of racial/ethnic discrimination in relation to child cardiometabolic health. In this study, we investigated whether maternal experiences of ethnic discrimination were associated with cardiometabolic risk in Hispanic/Latino youth several years later. Methods Our sample included 1,146 youth (8 to 16 years) from the Study of Latino (SOL) Youth (2012-2014), who were children of the Hispanic Community Health Study/Study of Latinos participants (HCHS/SOL; 2008-2011). We used regression models to examine the prospective associations between maternal-report of ethnic discrimination in relation to her child’s body mass index (BMI) z-score, metabolic syndrome score (MetS), and C-reactive protein (hsCRP) levels two years later. Results Maternal ethnic discrimination was associated with youth hsCRP, but not BMI or MetS ( p -values>.05). Adjusting for age, nativity, and national background, maternal ethnic discrimination was associated with higher (log) hsCRP levels (β=0.18, 95% CI=0.04—0.32) in children. This association was robust to adjustment for maternal and household characteristics (β=0.17, 95% CI=0.04—0.31), as well as maternal depression and maternal BMI. Conclusions Maternal ethnic discrimination is associated with inflammation among Hispanic/Latino youth, and not BMI z-score or MetS. Studies are needed to address temporality and pathways.
