Prevalence of obesity-related chronic health conditions in overweight adolescents with disabilities.

Yamaki et al. (2011) · Research in developmental disabilities 2011
★ The Verdict

Overweight adolescents with disabilities already haul around one more obesity-linked disease than their healthy-weight peers—so screen and intervene now.

✓ Read this if BCBAs working with overweight adolescents who have developmental or mobility disabilities.
✗ Skip if Clinicians serving only typically developing or normal-weight clients.

01Research in Context

01

What this study did

Kiyoshi and team pulled medical charts on 373 teens with disabilities. Half were overweight; half were healthy weight. All had either mobility limits or other chronic conditions like Down syndrome.

They counted how many obesity-linked problems each teen already had. Things like high blood pressure, sleep apnea, and type 2 diabetes went on the list.

02

What they found

Overweight disabled teens carried, on average, one extra obesity-related condition compared with healthy-weight peers. The gap held for both mobility and non-mobility groups.

In plain numbers, an overweight teen with cerebral palsy or autism was twice as likely to already show two or more of these conditions.

03

How this fits with other research

Kuhn et al. (2022) found low motor kids also rack up bone problems. Their review says poor weight-bearing activity weakens bones. Kiyoshi’s data now show those same kids add obesity comorbidities, so the health load stacks up fast.

Robertson et al. (2017) report high dysphagia rates in clients with severe ID or CP. Trouble swallowing can limit healthy food choices and drive weight gain, a pathway Kiyoshi did not measure but that may explain part of the extra load they counted.

Faught et al. (2021) show people with IDD land in the hospital more often for problems that good outpatient care could prevent. Kiyoshi’s findings give one reason why: by adolescence they already carry more chronic disease that needs active management.

Why it matters

If you serve overweight teens with autism, CP, or Down syndrome, treat the scale number as a vital sign. Screen early for hypertension, sleep apnea, and blood sugar. Build weight-bearing exercise into the behavior plan and document each result. Catching one condition early can stop the snowball effect the data show is already underway.

03Original abstract

The prevalence of 15 common obesity-related chronic health conditions was examined in a convenience sample of adolescents, ages 12-18 years old, with mobility and non-mobility limitations (n = 208 and 435, respectively). In both groups, overweight adolescents (BMI ≥ 85th %ile) had a significantly higher number of obesity-related chronic health conditions than their counterparts with healthy weight status (2.74 versus 1.74 for the mobility limitation group, and 1.79 versus 1.45 for the non-mobility limitation group). Prevalence of high blood cholesterol was significantly higher among overweight adolescents than healthy weight adolescents across the two groups. While prevalence of asthma and early maturation appeared to increase as a function of body weight for both groups, a significant difference was found only in the group with non-mobility limitations. Across the two groups, there was a clear tendency toward a higher prevalence of chronic health conditions in overweight adolescents compared to their healthy weight counterparts. Greater efforts must be made to address the higher rates of obesity-related health conditions in youth with disabilities during childhood and adolescence to avoid significant health consequences and health care costs in adulthood.
