Background:The prevalence of being overweight and obese is increasing not just in the general population but also in individuals with intellectual disability (ID). Therefore, a need to identify factors contributing to overweight/obesity arises as this population is escalating.
Materials and Methods:This narrative review article summarizes pertinent research focusing on prevalence and the potential factors associated with overweight and obesity in adults with intellectual disability during the past decade.Results: Prevalence of being overweight and obese among adults with intellectual disability is reportedly 28%-71% and 17%-43%, respectively. Factors increasing the susceptibility of being overweight or obese have been identified as female gender, increasing age, having a certain diagnosis, mild intellectual disability, as well as living independently/with family, consuming certain prescription medications, and non-participation in physical activities.
Conclusion:Identification of the potential risk factors associated with being overweight and obese in this population will help tackle the challenges faced by this growing adult population with intellectual disability.

| INTRODUCTIONDuring the past decades, life expectancy of the people with intellectual disabilities (IDs) has increased considerably and follows similar increasing trends to those found in the general population except for those with Down syndrome or epilepsy and or severe and multiple disabilities (Coppus, 2013;Hosking et al., 2016;Patja, Iivanainen, Vesala, Oksanen, & Ruoppila, 2000). Data from the United Kingdom, however, report significantly higher mortality among individuals with intellectual disability compared to the general population; the median age at death of male and female individuals with intellectual disability being 65 and 63 years, respectively compared to 78 and 83 years in the general population (Heslop et al., 2014;Hosking et al., 2016).Most common causes of death among individuals with intellectual disability are reportedly cardiovascular diseases, respiratory diseases and neoplasms (Janicki et al., 2002;Patja, Molsa, & Iivanainen, 2001).In their large 35-year follow-up research, Patja et al. (2001) showed that the disease mortality pattern was high up to 40 years of age, but did not increase after that indicating that older people with intellectual disability had a similar mortality pattern to the general population.Health care professionals are therefore posed with new challenges, as lack of good-quality health care is reportedly an important contributory factor to mortality among this population (Heslop et al., 2014;Hosking et al., 2016).With more than one-third of adults (36.9% men & 38.0% women) in the world being overweight or obese (Ng et al., 2014), it is logical to believe that there is a rise or similar increasing trend in the prevalence of being overweight and obese in adults with intellectual disability.
