The authors tested whether Australians in utero during the Southern hemisphere flu peak would show increased suicidal & depressive symptoms, as would those born in the Northern hemisphere & who were in utero during the Northern hemisphere flu peak. 2514 adolescents & young adults completed measures of depressive & suicidal symptoms. Those born in the Southern hemisphere in September-November showed the highest suicidal & depressive symptoms, as did those born in the Northern hemisphere in March-May. The authors suggest that season of birth may be a risk factor for suicidal symptoms. (10 refs)
