Objectives: This report describes associations between chronic school absenteeism and selected developmental disabilities (DDs) among school-aged children. Methods: Using the 2014-2016 National Health Interview Survey, multivariate logistic regression models were fit to estimate the association between DDs (attention-deficit/hyperactivity disorder [ADHD], autism spectrum disorder, intellectual disability, or other developmental delay) and chronic school absenteeism controlling for demographics and co-occurring physical health conditions among children aged 5-17 years. Results: During 2014-2016, the overall prevalence of ADHD was 10.6%, autism spectrum disorder was 2.5%, intellectual disability was 1.3%, and other developmental delay was 3.8% among children aged 5-17 years. Children with some types of DDs examined had significantly higher odds of chronic absenteeism compared with children who did not have a DD. Specifically, children with ADHD (adjusted odds ratio [AOR]: 1.84; 95% confidence interval [CI]: 1.16-2.91), autism spectrum disorder (AOR: 2.89; 95% CI: 1.59-5.27), and intellectual disability (AOR: 1.57; 95% CI: 1.03-2.39) were more likely to have had chronic school absenteeism than children without these conditions. Conclusions: Children with DDs had higher chronic school absenteeism. Associations remained after controlling for demographics and co-occurring physical health conditions. Similarly as the number of DDs increased, the odds of chronic school absenteeism increased. These findings show that both the type and number of DDs are associated with school attendance.
