Obesity prevalence in two national cohorts of children with disabilities: Patterns over time and by disability subgroups.

This large study followed children with disabilities from kindergarten to grade 5, including children with autism, intellectual disability, learning disabilities, and speech/language problems. It found that obesity rates doubled during these school years, rising from about 17% to 28%. By grade 5, children with disabilities had much higher obesity rates than other children. All disability groups showed similar patterns, meaning even children with milder disabilities like speech problems need obesity prevention support.

This longitudinal study analyzed obesity prevalence in children with disabilities using two nationally representative US cohorts (ECLS-K 1999 and 2011) totaling approximately 18,300 children. The research tracked obesity rates from kindergarten to grade five across four disability subgroups: speech/language impairment, specific learning disability, intellectual disability, and autism spectrum disorder. Results showed obesity rates among children with disabilities increased significantly from 16-18% in kindergarten to 26-31% by grade five, consistently exceeding rates in typically developing peers by 4-7 percentage points. Importantly, obesity patterns were similar across all disability subgroups, including those traditionally considered less severe.

The findings highlight the need for targeted obesity prevention strategies for all children with disabilities, not just those with more complex needs.

Results indicate urgent need for obesity prevention programs targeting all children with disabilities from early school years. Prevention efforts should not focus solely on children with severe disabilities but include those with speech/language impairments and learning disabilities. Early intervention during kindergarten years may be critical given the substantial increase in obesity rates through elementary school.

The abstract does not specify methodological limitations, sample demographics, or potential confounding factors. The study appears descriptive rather than interventional, limiting causal inferences about obesity development. Specific measurement methods for obesity classification and disability categorization are not detailed.

Obesity in the United States disproportionately affects children with disabilities, yet little is known about how their obesity rates change over time or differ across disability subgroups. This study examined changes in obesity rates in two nationally representative cohorts of children from kindergarten to grade five. Obesity rates were further disaggregated for four less examined disability subgroups: speech or language impairment (SLI), specific learning disability (SLD), intellectual disability (ID), and autism spectrum disorder (ASD). Data from the Early Childhood Longitudinal Study-Kindergarten (ECLS-K: 1999 and ECLS-K: 2011) on two cohorts of children (approximately N = 9800 and N = 8500) were analyzed using logistic regression.

In both cohorts, obesity among children with disabilities increased from kindergarten (16-18 %) to grade five (26-31 %), at which point their rates were nearly 4-7 percentage points higher than children without disabilities. Obesity rates and grade-level trends were similar by disability subgroups in both cohorts. Our results underscore the importance of tracking dietary, behavioral, and physical activity changes in children with disabilities that may increase or mitigate their risks of obesity. Targeted obesity prevention efforts should also extend to children in the less severe SLI and SLD categories.
