Background: Sleep duration, associated with increased morbidity/mortality, has been shown to vary by race and occupation. Few studies have examined the additional influence of immigrant status. Methods: Using a nationally-representative sample of 175,244 US adults from the National Health Interview Survey from 2004-2011, we estimated prevalence ratios (PRs) for short sleep duration (<7 hours) among US- and non-US born Blacks and Latinos by occupation compared to their White counterparts using adjusted Poisson regression models with robust variance. Results: Non-US born participant's mean age was 46 years, 55% were men, 58% were Latino, and 65% lived in the US ³15 years. Short sleep prevalence was highest among US- and non-US born Blacks in all occupations, and the prevalence generally increased with increasing professional/management roles in Blacks and Latinos while it decreased in Whites. Adjusted short sleep was more prevalent in US-born Blacks compared to Whites in professional/management (PR=1.52 [95% confidence interval (CI): 1.42-1.63]), support services (PR=1.31 [95% CI: 1.26-1.37]), and laborers (PR=1.11 [95% CI: 1.06-1.16]). The Black-White comparison was even higher for non-US born Black laborers (PR=1.50 [95% CI: 1.24-1.80]). Similar for non-US born Latinos, Latinos born in the US had a higher short sleep prevalence in professional/management (PR=1.14 [95% CI: 1.04-1.24]) and support services (PR=1.06 [95% CI: 1.01-1.11]), but a lower prevalence among laborers (PR=0.77 [95% CI: 0.74-0.81]) compared to Whites. Discussion: Short sleep varied within and between immigrant status for some ethnicities in particular occupations, illuminating the need to understand sociocultural factors contributing to sleep disparities among US workers.
