What This Means
This research suggests that parents who care for children with intellectual and/or developmental disabilities (IDD) — such as autism, Down syndrome, or cerebral palsy — are significantly more likely to get less than 6 hours of sleep per night compared to parents of children without these conditions. Using a large, nationally representative survey of over 58,000 parents collected between 2011 and 2018, the researchers found that about 40% of parents of children with IDD reported insufficient sleep, compared to about 34% of other parents. After accounting for other factors like age, income, and education, parents of children with IDD were still 20% more likely to report not getting enough sleep.
Importantly, this research suggests that not all parents of children with IDD are equally affected. Parents with higher incomes or college degrees did not show a statistically significant increase in sleep problems, whereas parents with lower incomes and less education showed the strongest association with insufficient sleep. This points to the role of socioeconomic resources — such as access to respite care, support services, or flexible work schedules — in buffering the sleep challenges that come with caregiving.
This matters because chronic insufficient sleep is linked to a wide range of health problems, including cardiovascular disease, mental health conditions, and reduced immune function. Since parents of children with IDD already face elevated health risks, sleep deprivation may compound these challenges. The findings highlight the need for sleep health programs and support services that are specifically designed to reach families with fewer economic resources who are caring for children with disabilities.
