This study looked at hospital admissions to all Ontario facilities over a 6 yr period, with each yr divided into seasons. Statistically significant seasonal variation, with peaks in spring & fall, was found for neurotic & endogenous depression. Alcoholism also showed a spring peak. Overall, no other diagnoses showed seasonality. The findings are discussed in terms of their clinical & research significance. (25 refs)
