ObjectiveDespite the wealth of research investigating the association of unemployment with suicide in the West, few studies have investigated the association in non-Western countries. This study aimed to investigate the relationship between secular trends in unemployment and suicide in Taiwan.Study DesignTime-series analysis.MethodsOverall and age-specific suicide rates (1959-2007) for Taiwanese men and women aged 15 years or above were calculated from national population and mortality statistics. The association of secular trends in unemployment with suicide was investigated graphically and using time-series modelling (Prais-Winsten regression).ResultsRises in unemployment were associated with an increase in male suicide rates, but evidence for an association in females was limited. In the model controlling for changes in gross domestic product (GDP) per capita, GDP growth, divorce and female labour force participation, for every 1% rise in unemployment, male suicide rates increased by 3.1 (95% confidence interval 1.4-4.8) per 100,000. There is no evidence for a difference in the strength of association between men of different ages.ConclusionTrends in suicide, particularly for adult males, appear to be influenced by unemployment. The results have implications for suicide prevention, in particular for societies facing acute rises in unemployment during recessions.Copyright 2009 The Royal Society for Public Health.
