Non-fatal suicidal behaviour in Padua, Italy, in two different periods: 1992–1996 and 2002–2006

Purpose The WHO/EURO multicentre study on suicidal behaviour showed the lowest rates of suicide attempts in the Italian centre of Padua. Present study aims to discover changes in non-fatal suicidal behaviour rates and characteristics by comparing hospital-admitted subjects in two study periods (1992–1996 and 2002–2006). Methods Data were obtained from the University Hospital of Padua. The crude prevalence rates of events and persons by year per 100,000 (subjects aged 15? years) were calculated. Rate ratios, Chi-square tests and t tests were calculated. Results The mean prevalence rate per year showed a significant increase during the second study period from 59.2 to 93.6 per 100,000 (RR = 1.58, 95%CI = 1.24– 2.02). Changes were significant for both genders, but the increase was stronger in males. The proportion of subjects with non-fatal suicidal behaviour was highest in the youngest age group (15–29 years) in the first period and in adults (30–44 years) in the second period. The absolute number of subjects with non-fatal suicidal behaviour increased more than two times for adults aged 30–44 years. Changes in other age groups were minor. The absolute numbers of non-Italian-born subjects with non-fatal suicidal behaviour increased from 11 to 135 persons. The proportion of poisoning was significantly lower in the second period. Conclusions When comparing the time periods 1992– 1996 and 2002–2006, there was a significant increase in suicidal events in Padua. There have been remarkable changes in the characteristics of suicide attempt(er)s. The most remarkable change was in the number of non-Italianborn subjects, who should be specifically targeted by suicide prevention activities.
