title: [Relation of a suicidal behaviour with the heliogeophysical factors].
abstract: Heliogeophysical parameters of the environment at the time of realization of suicidal behaviours using the data of four independent cohorts from different Ukrainian regions, separately for men (totally 7585 cases) and women (totally 4023 cases) for interval of 1989-2008 were analysed. A suicidal behaviour of men is actualized when geomagnetic activity decreases after its maximum. Heliogeophysical factors have smaller influence on women's suicidal behaviour. Suicide bombing attacks in Israel, Iraq and Afghanistan (for the period from 1994 to 2008) tend to take place by the maximal values of geomagnetic activity or during changes in interplanetary magnetic field polarity from negative to positive. These findings promote future discussion regarding unifying psychological or psycho-physiological mechanisms in suicides and suicidal terroristic acts and have some predicting potential.
