• To investigate whether race (African American (AA) and white) is associated with sleep duration among adults from low socioeconomic (SES) strata and whether SES status, lifestyle behaviors, or health conditions are associated with sleep duration within race-sex groups. This cross-sectional study includes 78,549 participants from the Southern Community Cohort Study (SCCS). Averaged daily sleep duration was assessed by weighted averages of self-reported sleep duration on weekdays and weekends. Adjusted odds ratios (ORs) of very short (<5 h/day), short (5–6 h/day), and long sleep (≥9 h/day) associated with pre-selected risk factors in each race-sex group were determined by multinomial logistic models. The prevalence of very short and short sleep was similar among AAs (6.2% and 29.1%) and whites (6.5% and 29.1%). Long sleep was considerably more prevalent among AAs (19.3%) than whites (13.0%). Very short sleep was associated with lower education and family income, with stronger associations among whites. Higher physical activity levels significantly decreased odds for both very short (OR = 0.80) and long sleep (OR = 0.78). Smoking, alcohol use, and dietary intake were not associated with sleep duration. Regardless of race or sex, very short, short, and long sleep were significantly associated with self-reported health conditions, especially depression (ORs were 2.06, 1.33, and 1.38, respectively). Sleep duration patterns differed between AAs and whites from the underrepresented SCCS population with low SES. Sleep duration was associated with several socioeconomic, health behaviors, and health conditions depending on race and sex. •Association of sleep duration and socioeconomic status, health and lifestyle characteristics, and prevalence of chronic diseases were evaluated in a large cohort (n = 78,549) of underrepresented African American (AA) and white adults from the Southern Community Cohort Study (SCCS).•The prevalence of very short and short sleep durations was similar between AAs and whites, while AAs (19.3%) were more likely to experience long sleep duration than whites (13.0%), from the SCCS population with low socioeconomic status.•Lower household income was associated with very short and short sleep durations in whites but not AAs.•Very short, short, and long sleep durations were associated with physical activity and comorbid conditions such as depression and cardiovascular disease (CVD) and stroke, independently of race and sex.
