  1. Seasonality of births in affective disorder in an Irish population.

    Article - En anglais

    Seasonal variation in the births of patients with schizophrenia is a consistently replicated epidemiological finding.

    Few studies have investigated this phenomenon among patients with a diagnosis of affective disorder.

    The majority of season of birth studies have employed the chi square test for statistical analysis, a method that has been subject to some criticism.

    Using a Kolgomorov-Smirnov type statistic, the quarterly birth distribution of 6,646 patients with an ICD 9/10 diagnosis of affective disorder were compared to the general population.

    Only the births of those individuals with unipolar forms of affective disorder (n=4,393) differed significantly from the general population, with significant excesses and deficits in the second quarter and fourth quarter respectively.

    These results were not altered by application of the displacement test.
