Gender differences in lifetime psychiatric disorders between sons and daughters of alcoholic mothers: a pilot study

Lifetime prevalence of selected psychiatric disorders was assessed in 24 independent pairs of adult siblings (brother-sister) with an alcoholic mother, using the Diagnostic Interview Schedule. Adult females were as likely as adult males to have had one or more lifetime diagnosis of psychiatric disorder. Lifetime prevalence of affective disorders was the same in male and female siblings. Although not statistically significant, compared with their sister, men were 3 times more likely to have had a diagnosis of alcohol abuse/dependence, and 3.5 times more likely to have had a diagnosis of general anxiety disorder. When compared with their brother, women were 1.66 times more likely to have had a diagnosis of drug abuse/dependence, 3 times more likely to have had a diagnosis of panic disorder, and 6 times more likely to have been diagnosed with phobia; however, these differences were not significant.
