0875 Interrelations Among Race, Socioeconomic Status, Sleep Duration Variability, and Neurobehavior in Children with Obstructive Sleep Apnea Syndrome

Abstract

Introduction: There are racial and socioeconomic status disparities in child obstructive sleep apnea syndrome (OSAS) and in sleep patterns, but research on sleep patterns in children with OSAS is limited. This project examined interrelations among race, socioeconomic status (SES), sleep duration variability, and neurobehavior in children with OSAS. Methods: Baseline data were drawn from 464 children with OSAS (M age 7 years, SD 1.4 years; 49% male; 34% Black) participating in the Childhood Adenotonsillectomy Trial. Sleep duration variability was calculated as the coefficient of variation for 5-day sleep diaries. Linear regression was used to examine whether sleep duration variability was associated with child race (Black vs. non-black), SES (family income; maternal education; neighborhood distress index based on US Census data), z-scored body mass index, asthma, prematurity, and secondhand smoke exposure. We then examined whether sleep duration variability was associated with parent-and teacher-reported child neurobehavior including executive functioning (Behavior Rating Inventory of Executive Functioning) and inattention (Conners Rating Scale), adjusting for the variables included in the first regression analysis. Results: Black race was correlated with increased sleep duration variability (p = .05), but this association was not significant in the adjusted regression model. Secondhand smoke exposure was significantly associated with sleep duration variability (p
