DEPENDENCE OF SUICIDES FREQUENCY AMONG URBAN POPULATION OF CHUVASHIA ON THE TIME OF DAY AND ALCOHOL INGESTION
When evaluating 679 completed suicides committed by urban residents in the period between 1997-2002, it was established that on the average in one year during daylight hours their number amounted to 70.3 ±26.0 or 62.2% of cases, and in the nighttime - 42.8 ± 15.9 (37.8%). The critical hours of autoaggression were 15.0-17.59 o'clock (15.6 ±4.3%) and 18.0-20.59 o'clock (18.0 and 18.6 ±3.3%). Among abstinent men the peak of suicide falls at the time interval 9.0-11.59 o'clock, and in women regardless of alcohol consumption at 15.0-17.59 o'clock. Compared with the suicide com-mitters who didn't consume alcohol, in the blood and/or urine of men where alcohol was present, the time of suicide commitment significantly shifts to a later evening and/or nighttime. Women die from alcohol poisoning mostly at night, with significant rise at 21.0-23.59 o'clock, while men do it evenly during the period of 24 hours with a minor peak at 21,0-23.59 o'clock. The time of sunset and sunrise does not affect making the decision to commit suicide and death from alcohol poisoning.
