Abstract

Background: Few studies have investigated the extent to which self-reported sleep duration reflects objectively measured sleep duration among racially/ethnically diverse populations. Methods: We investigated the concordance of self-reported habitual sleep duration compared to 1) actigraphy-measured sleep duration and 2) in-home polysomnography (PSG) across Whites, Blacks, Hispanics and Chinese participants in the Multi-Ethnic Study of Atherosclerosis sleep study. Results: Self-reports were overestimates in all racial groups compared to PSG and actigraphy. Correlations between self-reported and PSG total sleep time were lower (¿=0.20 overall) with significantly greater correlation in Whites compared to the other groups (¿=0.31 for Whites; 0.15 Blacks; 0.16 Hispanics; and -0.02 Chinese). Self-reporting bias for total sleep time compared to wrist actigraphy was 66 minutes [95% CI: 61-71]) for Whites, 58 minutes [95% CI: 48-69]) for Blacks, 66 minutes [95% CI: 57-74]) for Hispanics, and 60 minutes [95% CI: 49-70]) for Chinese adults. Compared to PSG, self-reporting bias in Whites at 73 minutes [95% CI: 67-79]) was higher than in Blacks (54 minutes [95% CI: 42-65]) and Chinese (49 minutes [95% CI: 37-61]) but not different than Hispanics (67 minutes [95% CI: 56-78]). Slight agreement/concordance was observed between self-reported and actigraphy-based total sleep time (kw=0.14 for Whites, 0.10 for Blacks, 0.17 for Hispanics, and 0.11 for Chinese) and single-night in-home PSG (kw=0.08 for Whites, 0.04 for Blacks, 0.05 for Hispanics, and 0.01 for Chinese) across race/ethnicity. Conclusion: Correlations between self-reported and objectively measured sleep duration as well as biases in self-reported vs. PSG measurements significantly non-differentially varied by race/ethnicity.
