Population-based administrative data (2009-2012) from several sources were used to compare the health status and access to health services between a cohort of children in care with developmental disabilities (DD) (n=1,212) and a matched comparison group of children in care without DD (n=2,424). The two study groups were compared on a number of measures, including total respiratory morbidity, prevalence of diabetes, mood and anxiety disorders, continuity of care, injury-related hospitalizations, hospital-based dental care, and total number of ambulatory physician visits. Children in care with DD were significantly more likely to have a history of mood and anxiety disorders, respiratory illnesses, diabetes, hospital-based dental care, and injury-related hospitalizations compared to the matched comparison group. Children in care with DD also had significantly higher number of physician visits than children in the matched comparison group. No significant difference between the two study groups was found for continuity of care.
