Association of Exposure to Interpersonal Racism and Racial Disparities in Inadequate Sleep Risk

Objective: To examine the association between caregiver-report of their child's inadequate sleep and exposure to interpersonal racism within racially minoritized subpopulations.

Study design: We conducted cross-sectional analysis among racially minoritized 21 924 school-aged children and 27 142 adolescents using a National Survey of Children's Health sample from 2016 through 2021. Multivariable logistic regression models were fit to estimate predicted probabilities for the adjusted associations between caregiver-report of their child's inadequate sleep and prior exposure to interpersonal racism.

Results: In bivariate models, caregiver report of child exposure to interpersonal racism was significantly associated with a higher probability of inadequate sleep within non-Hispanic Asian American/Pacific Islander school-aged children, Hispanic adolescents, and non-Hispanic multiracial adolescents. After adjusting for covariates, only the association within Hispanic youth remained significant though attenuated. Unexpectedly, non-Hispanic Black school-age children exposed to racism had a lower probability of inadequate sleep than non-Hispanic Black children without exposure to racism after adjusting for covariates.

Conclusions: Nationally representative pooled data that showed caregiver-report of Hispanic adolescents' inadequate sleep was associated with their exposure to interpersonal racism, although an association with inadequate sleep was not found in other racially minoritized subpopulations. Examining within-race associations helps to assess more accurately risk and target efforts that seek to address racism-related stress among racially minoritized subpopulations.
