Social inequalities in suicide across three Argentine provinces before and after COVID-19 pandemic

Few studies have examined social inequalities in suicide by comparing the COVID-19 pandemic with previous years. These studies, largely concentrated on high-income countries, have produced mixed results and have not included post-pandemic years in their analyses. Our objective was to analyse social inequalities in suicide across Argentine provinces during the period 2015-2023.

This is a retrospective quantitative study based on secondary data analysis. We employed Poisson regressions to model the temporal trends in suicide rates by educational level in the provinces of Jujuy, Mendoza and San Juan from 2015 to 2023. Additionally, we calculated suicide rate ratios to examine temporal variations in relative inequalities by educational level.

Compared with those with medium-high education, individuals with low education-across sexes, men and the 25-44 age group-had higher suicide risk in all years except 2021. During the pandemic, women's educational mortality ratios fell below 1, contrasting with prepandemic (2015-2019) and postrestrictions (2022-2023) periods. For men, suicide rate ratios exceeded 1 in all periods but were smaller during and after the pandemic. The 25-44 age group mirrored men's pattern, while the 45+ group showed no educational inequalities in suicide during and after the pandemic.

The COVID-19 pandemic appeared to temporarily narrow the social suicide gap, though variations by sex and age were observed. This potential effect of the pandemic seemed to be short-lived, with the 2022-2023 period showing a return to prepandemic levels of social inequalities in suicide.
