Future uncertainty and socioeconomic inequalities in health: the Whitehall II study

Over the past 20 years, socioeconomic inequalities in mortality have widened, while job security and financial security have decreased. This paper examines the Whitehall II study, a longitudinal study of white-collar British civil servants. In the Whitehall II cohort socioeconomic gradients in morbidity and cardiovascular risk factors at Phase 5 (1997-99) were generally steeper than at Phase 1 (1985-88). We examine the contribution of job and financial insecurity to these at Phase 5 in 6770 women and men, all of whom were white-collar civil servants at Phase 1. Steep, inverse employment grade gradients were observed for all health measures at Phase 5, except cholesterol and systolic blood pressure in women. Gradients in the sub-population of non-employed participants tended to be steeper than gradients for participants in employment, although, with the exception of self-rated health and General Health Questionnaire (GHQ) score in men, differences were non-significant. Steep gradients in job insecurity were observed among employed participants (p
