0361 Birthplace Moderates Racial/Ethnic Disparities in Multiple Sleep Characteristics Among Non-Hispanic Whites and Hispanic/Latino Heritage Groups in the United States

Abstract

Abstract Introduction Sleep duration disparities by Hispanic/Latino heritage exist; however, few studies have additionally investigated sleep quality disparities by heritage and birthplace, nor have studies compared foreign-born to US-born Non-Hispanic Whites (NHWs). Methods Using pooled 2004-2017 National Health Interview Survey data, we investigated whether sleep disparities varied by birthplace among adult NHWs and Hispanic/Latino heritage groups. Adjusting for sociodemographic and behavioral/clinical characteristics, survey-weighted Poisson regressions with robust variance estimated prevalence ratios (PRs) and 95% confidence intervals (CIs) of self-reported sleep characteristics. Sleep characteristics were compared among foreign-born NHWs and Hispanic/Latino heritage groups vs. US-born NHWs. Sleep characteristics were also compared across Hispanic/Latino heritage groups vs. foreign-born NHWs. Results Among 254,699 participants (Meanage±SE: 47±0.9 years; 49% female), 81% self-identified as NHW (n=207,154), 12% Mexican (n=30,100), 2% Puerto Rican n=5,077), 1% Cuban(n=2,518), 1% Dominican (n=1,658), and 3% Central/South American (n=8,162). Compared to US-born NHWs, foreign-born NHWs were more likely to report >9-hours sleep duration (PR=1.11[95% CI: 1.01-1.21]) and poor sleep quality (e.g., PRtrouble staying asleep=1.27[1.17-1.37]), and US-born Mexicans were no more likely to report shorter sleep duration while foreign-born Mexicans were less likely (PR<6-hours=0.52[0.47-0.57], PR6-<7-hours=0.72[0.68-0.76]). Although US-born and foreign-born Mexicans had lower prevalence of poor sleep quality compared to US-born NHWs, PRs were lowest for foreign-born Mexicans. Compared to foreign-born NHWs, US-born Mexicans were more likely to report shorter sleep duration, but foreign-born Mexicans were no more likely. Regardless of birthplace, Puerto Ricans were more likely (e.g., PR<6-hours=1.37[1.24-1.60]) and Cubans were less likely (e.g., PR<6-hours=0.81[0.68-0.96]) to report shorter sleep duration vs. US-born NHWs. Compared to US-born NHWs, Dominicans reported better sleep duration and quality. Sleep duration and quality did not differ among Dominicans vs. foreign-born NHWs. Conclusion Sleep disparities varied by birthplace and Hispanic/Latino heritage. Birthplace of both NHWs and racial/ethnic minority groups should be considered in disparities research.
