  1. A one year prevalence study of schizophrenia on Reunion Island.

    Article - En anglais

    Review of geographical comparisons of the prevalence of schizophrenic disorders found a ten-fold range difference between geographical contiguous groups, with high and low prevalence pockets.

    We performed a 1-year prevalence study of schizophrenia in a limited area of Reunion Island in the Indian Ocean, and analysed the prevalence variability in contiguous regions of this area.

    We found one of the highest reported age-corrected (above 15 years) 1-year prevalence of schizophrenia (14.9 per thousand).

    Large discrepancies in the distribution of prevalence rates of schizophrenia were observed between the five towns analysed.

    Interestingly, when a higher prevalence was observed, it was highly correlated with an increase of the percentage of familial cases (r=0.989, df=3, P=0.0014).

    Presence of founder effect often described in geographical isolates could explain the high prevalence rate and the heterogeneity between towns observed in our sample.
