In Sweden, suicide rates for adult men and women have remained constant for the past two decades despite the governments “zero vision” for suicide adopted in 2008. Several international studies have identified associations between suicide risk and certain occupations, such as work in agriculture, construction industry and medicine. However, in a Swedish setting, there is no corresponding recent data and it appears crucial identifying psychosocial workplace exposures in order to develop preventive actions.
1) To investigate suicidal behavior (attempted and completed suicides) among all Swedish males born in 1950-1983 over time in relation to occupational group and psychosocial workplace exposures.
2) Using survey data to determine individual-level psychosocial job exposures for suicidal behavior among male construction workers in Sweden.
3) To investigate the risk of suicidal behavior in Swedish women in relation to occupation and psychosocial workplace exposures.
To address these aims we will utilize:
1) The Swedish Conscript Register which comprises more than 1.6 million men examined in late adolescence during 1968-2001 and followed for suicidal behavior during 2002-2018.
2) The construction workers (n=370,000 men) that were recruited through healthcare examinations from 1971–1993 and followed regarding suicidal behavior during 1972-2018.
3) A cohort of 1.6 million women aged 18–45 years in the Swedish Medical Birth Register who gave birth during 1982-2016 followed for suicidal behavior during 2002-2018.
These three cohorts are linked to other nationwide registries including international standard classification of occupations, job-exposure matrices and National Patient and Death Registers. Hence, we have access to very detailed phenotype data, as well as outcome data for suicidal behavior during follow-up.
These findings could inform occupation- or work context specific interventions to prevent suicide in the working population.
