Differences in suicide behaviour in the elderly: A study in two provinces of Northern Italy

Background: to investigate the suicide phenomenon among the elderly (people aged 65 and over) in the Italian provinces of Novara and Verbania, in the time span between January 1990 and December 2000, in order to evaluate if the characteristics of the suicide behaviour correlate to the place of living with particular attention to the psychosocial factors. Methods: the information was collected from the Republic Procuration of the two provinces. Frequencies and contingency tables were evaluated to compare the data found in the two provinces. Standardised Mortality Ratios (SMRs) with their confidential intervals (95% confidence intervals) were calculated in comparison with the average suicide rates in North West Italy in the same period and in the same age group. Results: One hundred and eighty-four suicides were committed from the elderly, with an average rate of 14.07 per 100 000 inhabitants in Novara and 25.56 in Verbania. The most common methods used to commit suicide were hanging and jumping from height. The factors chiefly related to suicide were mental disease, followed by organic illness. The analysis of SMRs point out that the incidence of suicide in the province of Verbania is higher than in North West Italy while in Novara it is lower. Conclusion: the evaluation of the suicide risk in the elderly in a diagnostic and preventive framework must take into consideration the psychosocial factors that vary with the place of living.
