Five hundred and ninety-nine French-Canadian pre-adolescent children f
or whom the alcoholic status of the parents was Known were subdivided
into eight groups, according to family structure (intact, non-intact),
alcoholic status of the father (alcoholic, non-alcoholic) and gender
of the target child (girl, boy). ANCOVAs were conducted (controlling f
or income, a factor which contributes to illness) for health-related v
ariables in order to test the hypothesis that children of alcoholic fa
thers have more physical health problems compared to children without
alcoholic fathers. Data pertaining to use of medical services, serious
and minor illnesses and pregnancy-related events were analysed It was
found that overall, pre-adolescent children of alcoholics were not mo
re ill than children of non-alcoholics. There were, however, some diff
erences worthy of note. Children of alcoholics had significantly lower
birthweights than the children of non-alcoholics. Boys in non-intact
alcoholic families were of shorter stature than the other children. A
three-way interaction showed that daughters of alcoholics and sons of
non-alcoholics living in non-intact families were more likely to have
used psychologists' services, as were sons of alcoholics in intact fam
ilies. The results were discussed in terms of the heterogeneity of alc
oholic families as well as the need to identify subgroups of children
of alcoholics who are at risk.
