Among children of mothers with low education levels, those who receive regular care from other adults during preschool years may be less likely to have problems with physical aggression, according to a report in the November issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Hitting, kicking, biting and other forms of physical aggression are central features of a severe conduct disorder, according to background information in the article. These behaviors may be associated with social, physical, and mental health problems. “The origin of physical aggression problems can be traced back to early childhood, and studies have specifically shown that maternal characteristics, especially low levels of education, are among the best predictors of high physical aggression from early childhood to adolescence,” the authors write.

Of the 1,691 children who were followed for the whole study, 111 (6.6 percent) received no non-maternal care before preschool, 234 (13.8 percent) received some type of non-maternal care beginning before age 9 months and 1,346 (79.6 percent) received non-maternal care beginning at age 9 months or after. Children whose mothers had a low education level (i.e., did not have a high school diploma) were less likely to receive day care. However, children who did receive non-maternal care had lower levels of physical aggression, and the association was statistically significant among children who started day care before age 9 months.
Children of mothers who graduated from high school were at lower risk of developing physical aggression problems, and non-maternal care had no additional effect on their behavior.
“In summary, we provide robust evidence that the provision of non-maternal care services to children of mothers with low levels of education could substantially reduce their risk of chronic physical aggression, and that the protective impact is more important if children begin to receive these services before age 9 months,” the authors conclude. “Because the children most likely to benefit from non-maternal care services are those less likely to receive them, universal programs involving the provision of non-maternal care should include special measures encouraging the use of non-maternal care services among high-risk families.”
