Race and ethnic variation in excessive daytime sleepiness: the multi-ethnic study of atherosclerosis
Abstract
This cross-sectional study utilized data from the Multi-Ethnic Study of Atherosclerosis (MESA). The sample included 5,173 older adults (mean age = 66.4 years) recruited from 6 field centers in the United States. Excessive daytime sleepiness (EDS) was evaluated using two measures: self-report of feeling excessively sleepy ≤ 5 days per month and the Epworth Sleepiness Scale (ESS) > 12. White participants were more likely than other groups to report EDS ≤ 5 days per month. After controlling for covariates, African American and Hispanic participants remained less likely to report EDS ≤ 5 days per month. African Americans were more likely to score > 12 on the ESS than White participants. Odds ESS > 12 in African American participants were attenuated but remained significant after controlling for covariates. Results indicate measurement of race/ethnic differences in EDS may result in conflicting estimates of race/ethnic variation. Furthermore, attenuation of differences in ESS < 12 suggests this measure has a stronger association with current health.
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 5,173 participants or records.
