The article presents the study on the sleep problems among children aged 2 to 5 years with an autistic disorder in the U.S. The study measured children's sleep through parent report and through actigraphy at three times for 6 months. It is found that nighttime sleep problems were most prominent in the nonautistic group with developmental delays, while the autistic group napped less during the day.

Objective/background: Behavioral Sleep Interventions (BSI) is an efficacious class of treatment approaches for infant sleep disturbance. Little is known about BSI implementation in the real world. Objectives were to a) examine the prevalence of BSI implementation and related factors in a diverse sample of US mothers; b) assess racial-ethnic group differences; and c) examine predictors of BSI implementation., Participants: Participants included mothers ( n = 353) with an infant (6-18 months) from one of the three racial-ethnic groups: White Hispanic ( n = 113), White non-Hispanic ( n = 122), Black non-Hispanic ( n = 118)., Methods: Respondents completed an online survey assessing BSI implementation, familiarity, barriers, sleep knowledge, cognitions, and sleep patterns., Results: Approximately one-third (36%) of the sample endorsed BSI implementation and 59% reported BSI familiarity. Black non-Hispanic mothers were more likely to report stopping a BSI prior to completion (OR = 4.92, p <.05) and more likely to hear about BSI from a health-care professional (OR = 1.32, p <.05) compared to White non-Hispanic mothers. Racial-ethnic group differences were identified for a variety of sleep practices, including bedsharing, independent sleep onset, and score on a validated measure of problematic sleep. No racial-ethnic group differences were found in BSI implementation, cognitions, or barriers. BSI implementation was predicted by BSI familiarity, more maternal education, and cognitions around infant self-soothing., Conclusions: Differential BSI implementation does not appear to be a major driver of sleep disparities, although Black non-Hispanic mothers who decide to implement BSI do report notably lower completion rates. Future studies should examine alternative mechanisms of sleep disparities as well as strategies to promote sleep health in diverse families.
