Neighborhood built environment and sleep health: a longitudinal study in low-income and predominantly African-American neighborhoods.
The purpose of this study was to explore the relationships between physical characteristics of neighborhoods and sleep health outcomes and evaluated the mediating role of physical activity in these relationships. The researchers conducted the longitudinal Pittsburgh Hill/Homewood Research on Eating, Shopping, and Health (PHRESH) Zzz Study in 2 low-income, primarily African-American neighborhoods in Pittsburgh, Pennsylvania (n = 1,051). The study included repeated measures of neighborhood characteristics and sleep health outcomes from 2013 to 2018, and systematic field observations captured built environment measures of walkability, urban design, and neighborhood disorder. Sleep health outcomes included insufficient sleep, sleep duration, wakefulness after sleep onset, and sleep efficiency. Urban design features were correlated with lower levels of wakefulness after sleep onset. Neighborhood disorder and crime rate were negatively related with sleep efficiency. Neighborhood walkability was not associated with sleep outcomes.

Racial/ethnic disparities in sleep-disordered breathing during pregnancy in the nuMoM2b study.
This study’s aim was to assess the prevalence and severity of sleep-disordered breathing (SDB) across racial/ethnic groups in 3702 pregnant people at 6 to 15 and 22 to 31 weeks gestational age; examine whether BMI modifies the association between race/ethnicity and SDB; and investigate whether interventions to reduce weight might reduce racial/ethnic disparities in SDB. The study cohort consisted of comprised 61.2% non-Hispanic White (nHW), 11.9% non-Hispanic Black (nHB), 18.5% Hispanic, and 3.7% Asian persons. SDB prevalence was higher for nHB compared with nHW pregnant people at 6 to 15 weeks, whereas at 21 to 32 weeks, Asian pregnant people had a higher SDB prevalence than nHW. The severity of SDB differed across racial/ethnic groups in early pregnancy, with nHB pregnant people having a higher apnea-hypopnea index (AHI) compared with nHW. Having overweight/obesity was associated with a higher AHI.
