Reducing Sleep Disparities in Minority Children

Study Summary

Inadequate sleep is a major health problem of childhood that often fails to receive attention until significant neurobehavioral and other health problems are noted. Although adequate sleep is essential for normal growth and brain development, studies show that children from minority and economically disadvantaged families are more likely to experience shorter sleep times and more sleep fragmentation compared to their Caucasian and economically advantaged counterparts. As a result, they are disproportionately affected by the adverse health and quality of life consequences of poor sleep. There are currently no intervention studies to the investigators knowledge aimed at addressing sleep disparities by improving sleep duration and sleep hygiene in early school-aged children from minority populations. This study seeks to close the 'sleep gap' that exists between the sleep duration of minority school-aged children and that of their non-minority peers. An interdisciplinary team of researchers and clinicians from Columbia University's Pediatric Lung and Sleep Disorders Center, School of Public Health, Psychiatry Department, and two outpatient clinic systems affiliated with Columbia are collaborating to reduce sleep disparities by improving sleep duration in a group of 5-6 year old minority children. The primary goal of this study is to evaluate the efficacy of a tailored, interactive, educational and behavioral intervention that utilizes trained sleep counselors to assist parents in improving their children's sleep hygiene and reducing risk factors for poor sleep, thereby increasing sleep duration over a 12-month period in a randomized controlled trial of children identified with sleep problems (Aim 1). The investigators will screen 375 parents of 5-6 year old children from 5 primary care clinics to identify children with and without sleep problems and enroll 90 of the 375 children screened who have sleep problems in a randomized controlled trial of an in-home sleep interv

Primary Outcome

The primary outcome is nightly sleep duration and is objectively measured using actigraphy. The actigraph is worn on the non-dominant wrist for 7 consecutive days and nights. Actigraphy is a well-validated method for evaluating sleep and circadian rhythm patterns in children. It is highly correlated with polysomnography. To reduce potential confounders, Actiwatches are worn 5 times during the study, at baseline and at 3, 6, 9, 12 months following collection of baseline data.
