THE SPRING-AND-SUMMER PERIOD AS AN ADDITIONAL RISK FACTOR FOR ALCOHOLIC PSYCHOSES
Year-wise trends in alcoholic psychoses (AP; n=200799), other psychoses (n=19621), and deaths from alcoholic poisoning (n=35367) in seven cities of Russia and in Crimea (basing on the published data), as well as the sales of alcoholic beverage in Moscow were studied. It was found that typical trend of AP has two maximums - in January and in summer months; and one minimum - in February. It was shown that summer increase of AP incidence is not related to the alcohol consumption which decreases in summer time as well as the incidence of alcoholic poisoning. No increase of schizophrenic, organic, and senile psychoses was noted in summer time. It was concluded that summer weather conditions are an additional risk factor for AP incidence increase (which amounts to approximately 30% in summer months).
