SEASONALITY AND SUICIDE / Шинэ санаа Шинэ нээлт

ABSTRACT

Seasonality in suicide is one of those topics in epidemiology that we believe to know much about but understand fairly little in actuality. Since the 19th century many scholars have reported uniformly higher suicide frequencies in spring and summer than in autumn and winter. There had been very few studies on seasonality of Mongolian suicide. In this research, we wanted tofind the seasonal pattern and the relationship between behavioral characteristic and seasonal variation of suicide.This study is based on records provided by the local Health Centers of 21 provinces, particularly psychiatric-addiction care units; all local prosecution offices rural areasand 8 central organizations, which are registered suicide cases. We conducted the study by descriptive and retrospective design. Seasonal spring and early summer peak of suicide emerged in total suicide population. All concerned suicidecases were much more registered in spring time, and fatalsuicidalbehaviorcases registered fewer in autumn. National average percentage of fatal and non-fatalsuicidal behaviorcases was approximately in either seasons, but much more registered in spring time (x2=2.81; p≤0.000). Also most of fatal suicidal behavior cases were notedduring less human alertness hours in work days (x2=19.732a; p≤0.020).Seasonal variations of fatal suicidal behavioral haracteristic might play very important roles in suicide study.
