Key result
Severe intellectual disability is linked to lower lung capacity and handgrip strength versus milder forms.
Why the study?
Limited research had examined health and fitness indicators among individuals across different categories of intellectual disabilities.
Do health and physical fitness indicators differ among individuals with different levels of intellectual disability?
Cross-Sectional (n=203)
Do health and physical fitness indicators differ among individuals with different levels of intellectual disability?
Lung capacity and handgrip strength are sensitive health and physical fitness risk markers that correlate with the severity of intellectual disability.
May support tailored fitness screening by ID severity; leaves open whether interventions improve outcomes.
Background: Limited research has examined health and fitness indicators among individuals with different categories of intellectual disabilities (ID). The purpose of this brief report was to examine differences in health and physical fitness indicators among individuals with different levels of ID.Method: Individuals (n = 203) with mild, moderate, and severe ID completed a health and fitness screening. The health screening included blood pressure and lung capacity. Fitness measures were body composition, balance, and strength. We conducted multivariate analysis of covariance (MANCOVA) to examine level differences, controlling for age and gender.Results: Individuals with severe ID had significantly lower lung capacity than those with moderate ID, who had lower than those with mild ID. Individuals with mild ID had significantly higher handgrip strength than those with moderate ID, who had higher strength than those with severe ID.Conclusions: Lung capacity and handgrip strength are sensitive health and physical fitness risk markers for ID levels in China.

Zhang et al. (2019) conducted a cross-sectional in Intellectual disabilities (n=203). Level of intellectual disability vs. Different levels of intellectual disability was evaluated on Lung capacity and handgrip strength. Severe intellectual disability was associated with significantly lower lung capacity and handgrip strength compared to moderate and mild intellectual disability.
