Examining Trends and Coexisting Conditions Among Children Qualifying for SSI Under ADHD, ASD, and ID

Area of Science:

• Pediatric health services research
• Neurodevelopmental disorders
• Public health policy

Background:

• Attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and intellectual disability (ID) are significant concerns in pediatric populations.
• Understanding prevalence trends and co-occurring conditions is crucial for resource allocation and healthcare planning.

Purpose of the Study:

• To analyze prevalence trends of ADHD, ASD, and ID in children receiving Supplemental Security Income (SSI) compared to the general population.
• To investigate coexisting conditions associated with these diagnoses in both populations.

Main Methods:

• Utilized data from the Social Security Administration (SSA) for SSI recipients (2000-2011).
• Compared SSA data with National Health Interview Survey data for the general population (2000-2011).
• Employed linear regression analysis to assess trends and differences in prevalence.

Main Results:

• The SSI population showed increased prevalence of ADHD (5.8%) and ASD (7.2%), and decreased ID (-10.3%).
• Significant differences in ASD and ID trends were observed between SSI and general populations, unlike ADHD.
• SSI recipients with ADHD had higher rates of coexisting conditions than the general population, while those with ASD and ID had lower rates.

Conclusions:

• The rise in ADHD among SSI recipients mirrors general population trends, suggesting expected increases.
• Observed changes in ASD and ID prevalence within the SSI group may indicate shifts in diagnostic practices or true prevalence changes.
• Comparability limitations between the SSA and general population datasets were noted.
