Economic recession and cardiovascular disease among women: a cohort study from Eastern Finland

Little is known about the effect of economic recessions on cardiovascular disease. Therefore, we investigated the association of the economic recession in Finland in the 1990s with the incidence of cardiovascular disease among middle-aged and older women.

A total of 918 women aged 53-73 years were examined for health and socioeconomic position in 1998-2001, as part of the population-based prospective Kuopio Ischaemic Heart Disease Risk Factor Study. The participants were asked whether Finland's economic recession in the early 1990s had affected their lives socially or economically. The cohort was followed for 18 years, and incident physician-diagnosed cases of cardiovascular disease were obtained through record linkage with the national hospital discharge registry that covers every hospitalisation in Finland. Cox proportional hazards regression models were used to estimate the risk of cardiovascular disease among those with and without exposure to socioeconomic hardships during the recession, after adjusting for possible confounders.

At the baseline, 587 women reported having experienced socioeconomic hardships due to the recession. During the 20 years' follow-up, 501 women developed cardiovascular disease. After adjustment for age, the risk of cardiovascular disease was 27% higher among women exposed to socioeconomic hardships compared to those who were not (hazard ratio 1.27, 95% confidence interval 1.06-1.53, P=0.012). Further adjustments for overall socioeconomic position at baseline, prior cardiovascular health, and lifestyle factors did not attenuate the association (hazard ratio 1.23, 95% confidence interval 1.02-1.5, P=0.029).

The early 1990s economic recession was associated with a subsequently increased risk of cardiovascular disease among Finnish women.
