title: Continuity of health insurance coverage among young adults with disabilities.
abstract: OBJECTIVE
  Although considered critical to facilitate the successful transition from pediatric to adult health care, the continuity of insurance coverage for young adults with disabilities as they make the transition to adulthood has not been well characterized. The purpose of this work was to compare the continuity of insurance coverage reported by a nationally representative sample of young adults 16 to 25 years old with and without disabilities during a consecutive 36-month period.
  
  
  METHODS
  We performed secondary analysis of data from the 2001 Survey of Income Program and Participation. Data for the survey were collected at 4-month intervals from February 2001 through January 2004 for 5170 young adults. Subjects with disabilities were those who reported limitations in activities of daily living or work, used assistive devices, and/or had learning disabilities, mental retardation, or other mental disorders. The primary outcome was uninsurance defined for each study month in which there was no coverage by private, public, or military programs. We present bivariate analyses of the months of uninsurance according to disability status using longitudinal weights and design-effect adjustments to account for the complex sample design.
  
  
  RESULTS
  The sample consisted of 599 subjects with and 4571 without reported disabilities, representing 3,970,000 and 30,800,000 young adults in the United States, respectively. At study entry, 22% of the young adults with disabilities were uninsured. During the 36-month follow-up period, 56% of the young adults with disability reported gaps in insurance coverage with a mean of 15 months of uninsurance. The proportion of uninsured subjects did not significantly differ by disability status.
  
  
  CONCLUSIONS
  The majority of young adults with disabilities reported gaps in insurance coverage, and many were uninsured for a substantial portion of the study period. As an increasing number of children with special health care needs make the transition to adulthood, improving the continuity of health insurance coverage for this population warrants specific attention.
