Body mass index among Special Olympics athletes from Muslim majority countries: Differences in gender and adult...

Obesity is higher in adults with intellectual disability than in the general population and for women more than men. Past research however has specifically focused on individuals with intellectual disability in the United States and the United Kingdom with little attention on individuals with intellectual disability in Muslim majority countries.

The present study examined differences in body mass index (BMI) among 1314 men and women Special Olympics athletes from 32 Muslim majority countries in 2003, 2005, 2006, 2007, 2009 and 2011. Athletes' gender, adult status (minor or adult) and the interaction between gender and adult status were used to predict increases in BMI with a hierarchical linear regression, where athletes were nested within country controlling for athletes' nation's Gross-domestic product.

Being female significantly predicted an increase in obesity while adulthood predicted a decrease in BMI. The interaction between gender and adulthood was also significant, however, indicating that obesity decreases with adulthood only for men. For women, BMI continues to increase with age.

This study extends our knowledge on one important indicator of health status for individuals with intellectual disability in Asia, Africa and Eastern Europe. The results may be used to inform health care practices with individuals with intellectual disabilities and stimulate future research to understand contextual factors contributing to health disparities.
