Suicide mortality in Italy during the first year of the COVID-19 pandemic

Italy was severely hit by COVID-19 during 2020 and great concern about the possible increase of suicide rates in the population has arisen since early pandemic phases. Analyses limited to March-April have shown a drop in suicides in both sexes. This study aims to analyze suicide mortality in Italy during the whole 2020 making comparisons with the pre-pandemic period 2015-19, by sex, age and geographic area.

Official cause-of-death data with national coverage were used to analyze suicide mortality by sex, month, age class and geographic area in the population aged ≥10 years (54,595,179). The monthly number of suicide deaths in 2020 was compared to the average number in 2015-19. Age-specific and age-adjusted suicide rates in 2020 and in 2015-19 were compared using rate-ratios with 95 % confidence intervals.

Compared to 2015-19 a non-significant reduction of the overall suicide rate was observed during 2020, both in males (-3 %) and females (-7 %). Suicide rates non-significantly decreased in most age groups; an increase, although not statistically significant, was found among males aged ≥75 years and females aged ≥85 years. Suicide deaths reduced mainly in Central-Southern areas and the Islands, while they slightly increased in the North especially among males.

Study limitations include accuracy of death certification and the relatively brief observation period.

The study contributes to the analysis of early effects of the COVID-19 pandemic on suicide mortality in the whole population highlighting sex, age and territorial differences and suggesting to monitor possible increases in a longer observation period.
