Purpose
To investigate the association between healthy Nordic diet and risk of disease death in middle-aged and older men from eastern Finland.
Methods
A total of 1547 men aged 42–60 years and free of cardiovascular disease (CVD), cancer and type 2 diabetes at baseline in 1984–1989 were included. Diet was assessed with 4-day food records at baseline and the healthy Nordic diet score was calculated based on the Baltic Sea Diet Score. The incidence of death was assessed by a computer linkage to the national cause of death register. Cox proportional hazards regression analyses were used to estimate the associations between the healthy Nordic diet score and mortality.
Results
During the mean follow-up of 23.6 years (SD 7.0), 576 men died due to disease: 250 due to CVD, 194 due to cancer and 132 due to other diseases. The multivariable-adjusted hazard ratios (95% confidence interval) in the lowest vs. the highest quartile of the healthy Nordic diet score were 1.27 (1.01–1.59) for any disease death (P-trend across quartiles < 0.001), 1.39 (0.99–1.97, P-trend = 0.049) for CVD death, 1.26 (0.84–1.89, P-trend = 0.316) for cancer death and 1.04 (0.65–1.68, P-trend = 0.563) for other disease deaths.
Conclusions
In this prospective population-based cohort study among middle-aged and older men, low adherence to a healthy Nordic diet was associated with a higher risk of any disease death, possibly largely attributable to higher CVD mortality.
