Does job promotion affect men's and women's health differently? Dynamic panel models with fixed effects.

BACKGROUND

Higher occupational status has consistently been shown to be associated with better health, but few studies have to date examined if an upward change in occupational status is associated with a positive change in health. Furthermore, very little is known about whether this association differs by sex.

METHODS

Data were derived from four waves (2008-14) of the Swedish Longitudinal Occupational Survey of Health (SLOSH), a follow-up study of a nationally representative sample of the Swedish working population. The present study comprises 1410 men and 1926 women. A dynamic panel model with fixed effects was used to analyse the lagged association between job promotion on the one hand and self-rated health (SRH) and symptoms of depression on the other. This method allowed controlling for unobserved time-invariant confounders and determining the direction of causality between the variables. Multigroup comparisons were performed to investigate differences between the sexes.

RESULTS

The results showed that job promotion was associated with decreased subsequent SRH and increased symptoms of depression among both men and women. Women reported a larger relative worsening of self-rated health following a job promotion than men and men reported a larger relative worsening of depression symptoms. There was limited evidence that SRH and symptoms of depression were associated with subsequent job promotion.

CONCLUSIONS

The present study indicates that a job promotion could lead to decreased SRH and increased symptoms of depression in a 2-4-year perspective. Associations appear to differ for women and men.
