A century of suicide in Italy: a comparison between the old and the young.

This study analyzes suicide rates from 1887 to 1993 in the Italian population between the ages of 15 and 24 years old and over 65 years of age, based on official data published in the Health Statistics Year Book. The rates of death by suicide (per 100,000) subjects) are calculated for each year and for 10-year periods, as are the mortality rates relative to each method of suicide, standardized by gender. The latter analysis was possible starting from 1951 only, when it became customary to record method. The findings indicate an increase in the suicide phenomenon in the elderly population in Italy over the test period. Rates are at least 3 times higher for men than for women. The highest rates are reported for elderly men, but there appears to have been a greater proportional increase in the number of suicides committed by elderly women. The rise was statistically significant in both males and females. By contrast, a rather constant decrease in suicide rates in young people emerges from the beginning of the century through to the present date. This decrease is more marked in females, although suicide rates are lower for females than for males. Over the study period, substantial changes have come about in the suicide methods used by both young and old people. There was an increase in poisoning by care exhaust fumes, jumping from heights, hanging, and firearms.
