Variables related to body-weight status of mentally retarded adults

Mentally retarded male and female adult subjects displayed mean body weights in excess of their ideal weights; excessive body weight of females was also apparent in comparison to normative data for the United States. Maintenance of appropriate weight appeared to be more likely in a controlled residential setting than in the natural home environment. These sex and environmental relationships could not be explained by medication and dietary programming differences, and age, race, and level of retardation were unrelated to body weight.
