Rocchi M. B. L., Marchionni P., Perlini C.
Background. To characterize statistically the evolution of the suicide pattern (choice of suicide method and characteristic of suicide subject) in the 35-year period 1960-1994.
Methods. A set of suicide data, represented by all the consecutives suicides occurred between 1960 and 1994 in the Mountain District of the Upper Metauro River Valley (Marche, Italy) has been analyzed retrospectively. Data were collected from the Nominative Mortality Register Covering All Causes, of the regional Health Service of Urbino. The statistical analyses concerning temporal trends have been performed using the chi square test for trend, while the comparisons of proportions regarding the whole period have been performed applying the chi square test, after that the expected frequencies were computed according to the population structure.
Results. An unbalanced ratio was pointed out regarding both sex and age; this survey shows that males have higher risk (and that this risk has increased in the last 15-year period) and that older subjects (>60) have been at higher risk in the past, but now this trend has been inverted. No significant trend has been found about other variables (marital status, abode, choice of suicide method).
Conclusions. A significant trend regarding a change in suicide pattern (towards younger and males subjects) has been pointed out; no change has been shown for the other examined variables.
