Objective:
Describe the cumulative incidence of suicide mortality and self-inflicted injuries in Spain during the period 1987-1991 and identify associated socioeconomic and meteorological factors.
Design:
Ecological study. SITE: Fifty Spanish provinces excluding Ceuta and Melilla.
Patients:
Spanish population during the study period.
Main Measurements And Results:
For each province, the cumulative incidence of mortality from suicide and self-inflicted injuries were calculated by gender and age groups. The associations between suicide mortality and 31 socioeconomical and meteorological variables were evaluated using multiple linear regression. The incidence of suicide deaths was stable during the study period. The most important negative associations identified were with variables indicating economical development and the positive associations with the variable measuring specific general mortality. No significant differences between genders were found. For both genders, the model with the highest coefficient of determination corresponded to the group of adults aged.
Conclusions:
In Spain, social and economical factors are associated with the frequency of deaths from suicide and self-inflicted injuries in both genders and specially in the adult age.
