Lost Futures: The Human and Economic Cost of Suicide in Türkiye, 2012–2023

<b>Background/Objectives</b>: Suicide is a critical public health issue that leads to premature mortality among young people and requires substantial public health interventions. Demonstrating the importance of developing effective suicide prevention programs through health indicators can be valuable. This study aims to examine the change in suicide rates and Years of Life Lost (YLL) in Türkiye over the 2013-2023 period-a country that displays characteristics of both developed and developing nations-and to reveal the productivity losses using the human capital approach. <b>Methods</b>: The data for this descriptive study were obtained from the Turkish Statistical Institute between 2012 and 2023. YLL was computed by determining the difference between the age at which an individual died by suicide and their expected age of death for both males and females. Years of Potential Life Lost (YPLL) was estimated using the same method as YLL for individuals aged 15-64 (working age). The time trend of suicide and YLL rates was calculated using Annual Percentage Change and the Average Annual Percent Change values, based on a Poisson-based Generalized Linear Model and the Joinpoint regression method. Using the human capital approach, the economic cost of the labor force lost due to suicide was estimated. <b>Results</b>: The YLL per death was 33.57 years for males, 47.73 years for females, and 37.06 years overall. The age group with the highest YLL percentage is 20-24 among males (23.55%) and 15-19 among females (33.06%). An increase of 7.8% was observed among males from 2018 to 2021. The mean changes in the overall time trend were found to be significant in male suicides. Among females, there was a 5.3% decrease until 2017, followed by a 4.5% increase from 2017 onwards. Combined, male and female suicide rates have significantly increased since 2017. The financial loss associated with suicide over a 12-year period totaled USD 10,775,943,197 with an annual loss of USD 897,995,266. The premature mortality cost per death was estimated at USD 278,400.84 for men and USD 186,625.16 for women, while the premature mortality cost per YLL was USD 8292.23 for men and USD 3910.36 for women. <b>Conclusions</b>: Changes in the temporal trend of suicide may be associated with societal events. The study reveals that premature deaths due to suicide in Türkiye are a multidimensional public health problem that significantly affects not only individuals but also the overall productivity and economic structure of society.
