| Research Abstract |
We examined the relationship between geomagnetic disturbance and the number of suicides in Japan with adjustment for other factors. In the multiple linear regression (MLR) analysis for males, the monthly mean K index value was associated with the monthly number of suicides, but in females, the monthly mean K index value was not associated with the monthly number of suicides. If such a relationship exists, stronger geomagnetic fields may affect the number of suicides, because stronger geomagnetic fields generally cause larger geomagnetic field disturbances. Therefore, we investigated the relationship between local geomagnetic field magnetic flux density and the standardized morbidity ratios for suicide by each prefecture. In the MLR analysis for males, the local geomagnetic field magnetic flux density were associated with the incidence of suicide, but in the MLR analysis of females, the local geomagnetic field magnetic flux density were not associated with the incidence of suicide.
