The Mediterranean island of Sardinia shows the highest suicide rate in Italy among men (23.07 x 10(5) per year vs the average national rate of 13.80 x 10(5) per year). In contrast, the suicide rate among Sardinian women is one of the lowest across all the Italian regions. The aim of this epidemiological study was to investigate the distribution of suicide mortality in Sardinia in relation with environmental and social factors using geospatial analysis. Data available from the total 377 Sardinian municipalities, including suicidal mortality and several socio-economic indicators, were retrieved and analysed. Ordinary least squares regression was used to investigate the association between suicide mortality and the selected indicators. Suicides among men reached a peak in the Southern-Eastern area of the island. Overall, the multivariable analysis showed that suicidal mortality was significantly and positively related with the altitude (0.243, P = 0.001), the occupational hardship index (0.230, P = 0.016), and the social services hardship index (0.149, P < 0.0001), and negatively with pro-capita income (-0.122, P = 0.012). After adjusting for all covariates, the index of multiple deprivation, the environmental and the educational index respectively, remained the only significant predictors. These findings suggest that social distress is the main factor leading to suicide among Sardinia men.

Abstract

The Mediterranean island of Sardinia shows the highest suicide rate in Italy among men (23.07 x 10(5) per year vs the average national rate of 13.80 x 10(5) per year). In contrast, the suicide rate among Sardinian women is one of the lowest across all the Italian regions. The aim of this epidemiological study was to investigate the distribution of suicide mortality in Sardinia in relation with environmental and social factors using geospatial analysis. Data available from the total 377 Sardinian municipalities, including suicidal mortality and several socio-economic indicators, were retrieved and analysed. Ordinary least squares regression was used to investigate the association between suicide mortality and the selected indicators. Suicides among men reached a peak in the Southern-Eastern area of the island. Overall, the multivariable analysis showed that suicidal mortality was significantly and positively related with the altitude (0.243, P = 0.001), the occupational hardship index (0.230, P = 0.016), and the social services hardship index (0.149, P < 0.0001), and negatively with pro-capita income (-0.122, P = 0.012). After adjusting for all covariates, the index of multiple deprivation, the environmental and the educational index respectively, remained the only significant predictors. These findings suggest that social distress is the main factor leading to suicide among Sardinia men.
