Although most mothers of young children work, we do not know much abou
t the effect of this work on the mothers' health. The aim of this arti
cle is to review and discuss some of the findings on this subject, in
order to understand whether paid and unpaid work are associated with m
others' health. Results from available studies show that, while employ
ment tends to be associated with better physical and mental health in
mothers, its effects are inconsistent when mothers of babies or young
children are specifically examined. For physical health, employment is
likely to have a negative effect for working-class mothers and a posi
tive effect for middle-class ones. For mental health, the trend is unc
lear; mothers' psychological well-being is negatively affected, howeve
r, by the presence of one or more preschoolers, a lack of involvement
by the husband, difficulties linked to child care, and the women's pre
ferences concerning their professional status. Moreover, variables suc
h as education, income, social class, housing, and marital status are
likely to affect the health of mothers of young children, just as they
affect the health of other women.
