Health care use and health and functional impact of developmental disabilities among US children, 1997-2005.

OBJECTIVE: To present nationally representative estimates of health-related limitations, needs, and service use among US children with and without developmental disabilities (DDs).

DESIGN: Retrospective analysis of data from a sample of US households from the 1997-2005 National Health Interview Surveys.

PARTICIPANTS: Children aged 3 to 17 years (n = 95 132).

MAIN OUTCOME MEASURES: Parents or other knowledgeable adults reported on their children's DDs, health needs, and use of health and education services. Developmental disabilities included attention-deficit/hyperactivity disorder, autism, blindness, cerebral palsy, deaf/a lot of trouble hearing, learning disability, mental retardation, seizures, stuttering/stammering, and other developmental delay.

RESULTS: Among children with 1 or more DDs, prevalence estimates for limitations in movement (6.1%), needed help with personal care (3.2%), needed special equipment (3.5%), received home health care (1.4%), and regularly took prescription medication(s) (37.5%) were 4 to 32 times higher than for children without DDs. Children with DDs were 2 to 8 times as likely to have had more than 9 health care visits (14.9%), received special education (38.8%), had a surgical or medical procedure (7.5%), and recently visited a medical specialist (23.9%), mental health professional (26.6%), therapist/allied health professional (19.6%), and/or emergency department (10.3%). Effects were generally stable during the study interval and independent of age, race, sex, and family income. Cerebral palsy, autism, mental retardation, blindness, and deafness/a lot of trouble hearing were associated with the highest levels of health and functional impact indicators.

CONCLUSIONS: Developmental disabilities profoundly affect children's health and functioning. These data can inform evidence-based targeted prevention strategies for minimizing functional limitations and lifetime disability. Additional study of unmet needs and access to care is needed.
