Abstract

Aim: The aim was to analyse the association between economic stress during youth and adulthood, and poor mental health through life course models of (1) accumulation of risk and (2) sensitive period.

Methods: The study was based on the Northern Sweden Cohort, a 26-year prospective cohort (N = 1010 in 2007; 94% of those participating in 1981 still alive) ranging from adolescence to middle age. Economic stress was measured at age 16, 21, 30 and 42 years. Two life course models of accumulation of risk and sensitive period were analysed using ordinal regression with internalized symptoms of mental health as outcome.

Results: Exposure of economic stress at several life course periods was associated with higher odds of internalized mental health symptoms for both women and men, which supports the accumulated risk model. No support for a sensitive period was found for the whole sample. For men, however, adolescence appears to be a sensitive period during which the exposure to economic stress has negative mental health consequences later in life independently of economic stress at other ages.

Conclusion: This study confirms that the duration of economic stress between adolescence and middle age is important for mental health. In addition, the results give some indication of a sensitive period of exposure to economic stress during adolescence for men, although more research is needed to confirm possible gender differences.
