ABSTRACT
Aim To establish an influence of biometeorological phases on suicide incidence according to age, gender,
settlement, week days, months in a year, ways of suicide execution, influence of biometeorologic
phases on suicide execution.
Methods Comparative analysis of the data about suicides (by years, months, week days, settlements,
age, gender) obtained by the Police Department in Kragujevac for the 2004-2008 period and everyday
biometeorological phases (phase 1 CWD: cyclone, warm, dry; phase 2 CWW: cyclone, warm, wet;
phase 3 CWF: cyclone, warm front; phase 4 CCF: cyclone cold front; phase 5 CCW: cyclone, cold, wet;
phase 6 CCD: cyclone, cold, dry; phase 7 ACD: anticyclone, cold, dry; phase 8 ACW: anticyclone, cold,
wet; phase 9 AWD: anticyclone, warm, dry; phase 10 AWW: anticyclone, warm, wet) in Kragujevac
determinated by the Republic Hydrometeorology Institute of Serbia.
Results In the observed period there were 144 suicides resulting in the incidence rate of 14/100 000/
year. The highest number of suicides was noted in 2005 (36), and lowest one in 2007 (24). The most
suicide cases happened in January and June (18 in each), and the fewest in August (7). Three quarters
occurred in urban areas. Three quarters of victims were males mostly in the age groups 41-45 and 51-55
(11 in each). Females made one quarter of victims and most of them were in the age group 61-65 years
(7). Total mean age was 54,66 years. Two thirds of all suicides were executed by hanging (93) (two
thirds were among males), one sixth by firearms, with nine tenths of men. The most incidents with significant
correlation were in biometheorological phases 4 and 9 (stable sunny weather and sudden impact
of weather fronts, with sudden weather changes) (38 in each), which makes over a half of all suicides.
Conclusion According to the results of this study, it is strongly recommended to monitor everyday
biometeorological forecast , and special attention must be paid to all persons with suicide tendencies.
Key words: suicide incidence, biometeorological phases, weather conditions
