Objective Sleep Quality in Diverse Older Adults: the Importance of Race and Ethnicity and Sex.

ABSTRACT:

Background

Research on sleep disparities across different sociodemographic groups is limited and often yields inconsistent findings. We aimed to examine differences in objective sleep measures by race and ethnicity, sex, and age within a diverse cohort of community-dwelling older adults.

We compared sleep metrics across sociodemographic groups and assessed their multivariable
