Effects of maternal mental retardation and poverty on intellectual, academic, and behavioral status of school-age children.

The impact of low maternal IQ and poverty was examined through comparison of 27 school-age children of mothers with mild mental retardation to 25 similarly impoverished children of mothers without mental retardation. The children whose mothers had mental retardation had lower IQs and academic achievement and more behavior problems. Not one child with a mother who had mental retardation was problem-free. Boys were affected more severely than were girls. Quality of the home environment and maternal social supports were lower in the group with maternal mental retardation; both measures were negatively correlated with child behavior disorders. Results suggest that being raised by a mother with mental retardation can have detrimental effects on child development that cannot be attributed to poverty alone.
