social factors

Last reviewed 01/2018

There is an interaction between polygenic inheritance and adverse sociocultural influences.

There is a socioeconomic factor in the aetiology of about 2/3 of the mildly retarded group.

Research has identified a number of interrelated factors which are risk factors for mild mental retardation:

  • low socio-economic status
  • large families
  • poor housing
  • poverty
  • poor nutrition
  • inadequate stimulation
  • inadequate education

The retardation associated with this environmental deprivation may be preventable by attempting to intervene early to enrich the cultural environment.
