ECONOMIC RECESSION AND THE RISK OF CANCER - A Cohort Study from Eastern Finland.

BackgroundLittle is known about the role of economic recessions in the risk of cancer. Therefore, we evaluated the impact of the severe economic recession in Finland between 1991-1994 on the incidence of all cancers and cancer subtypes among middle-age and older population.MethodsFrom the Kuopio Ischemic Heart Disease Risk Factor Study (KIHD), a population-based sample of 1620 women and men aged 53-73 years were examined between 1998-2001. The cancer-free participants completed a questionnaire on the possible impact of the 1990s recession in Finland on their lives. Incident cases of cancer were obtained through record linkage with the Finnish Cancer Registry. Cox proportional hazards regression was used to estimate hazard ratios (HR) of incident cancer events after adjusting for possible confounders.ResultsA total of 1096 cancer-free participants had experienced socioeconomic hardships due to the recession at the baseline. During 20 years of follow-up, 473 participants developed cancer. After adjustment for age, baseline socioeconomic position and lifestyle factors, the risk of all cancers was 32% higher among men who experienced socioeconomic hardships compared to those who did not (HR 1.32, 95%CI, 0.99-1.75, p=0.05). Prostate-genital cancer was 71% higher among men with hardships (n=103, HR=1.71, 95%CI, 1.06-2.74, p=0.02). No association was observed between socioeconomic hardships and subsequent risk of total or any subtype of cancer among women.Conclusions:The 1990s economic recession was associated with increased risk of all cancers, especially prostate-genital cancer among Finnish middle-age and older men, but no association with cancer was observed in women.
