Long-term effects of youth unemployment on mental health: does an economic crisis make a difference?

BACKGROUND: Ill health is a risk factor and a consequence of unemployment, which might vary depending on the national rate of unemployment. We investigated the long-term effect of youth unemployment on mental health and explored the possible interaction during periods of high (economic crisis) and low (non-crisis) unemployment rates. METHODS: A register-linked population-based cohort study was conducted including individuals aged 17–24 years. The crisis cohort (n=6410) took part in the Labour Force Survey during the economic crisis (1991–1994) in Sweden and the non-crisis cohort (n=8162) took part in the same survey before the crisis (1983–1986). Follow-up was 19 years. Adjusted HRs and 95% CIs for an inpatient care discharge mental diagnosis with employed people as the reference group were calculated by Cox regressions models. RESULTS: In fully adjusted models, <3 months (HR: 1.69; 95% CI 1.14 to 2.49), 3–6 months (2.19; 1.43 to 3.37) and >6 months (2.70; 1.71 to 4.28) of unemployment were associated with increased risks of getting a mental diagnosis in the crisis cohort. In the non-crisis cohort the risks were: 1.92; 1.40 to 2.63, 2.60; 1.72 to 3.94 and 3.33; 2.00 to 5.57, respectively. No interactions between labour force status and level of unemployment were found. CONCLUSIONS: Youth unemployment is related to mental health problems, independent of the overall national rate of unemployment, which is important as the youth unemployment rates are currently at stable high level.
