The KIHD Study is an ongoing prospective population-based cohort study designed to investigate risk factors for CVD, atherosclerosis and related outcomes in middle-aged men from eastern Finland, the population with one of the highest recorded rates of CHD.
The study population is a random sample of men living in the Kuopio city and neighbouring rural communities, stratified and balanced into four strata: 42, 48, 54, or 60 years at the baseline examination. A total of 2682 participants (82.9 % those eligible), were enrolled in the study between 1984 and 1989.
The four-year examinations for the KIHD study were carried out during 1991 to 1993 for 1038 men. Eleven-year examinations were carried out in 1998 to 1999 for men and women and 20-year examinations 2006-8. Dietary intake of nutrients was assessed quantitatively with a four day food recording at the KIHD baseline and 11-year examinations.
The explanatory data at use includes factors from genomics through bioactive molecules, pathophysiological changes (such as abnormal ECG, changes during excersise test, atherosclerosis, findings from echocardiography etc) to individual behaviors, lifestyle, personality characteristics, psychological profiles, early life histories, worktime exposures, signs of cognitive impairment at later middle-age etc. The cohort are now starting to turn geriatric, and this will bring new interesting challenges for research in coming years.
We have recently joined many notable international research consortia, where our data has been pooled or analysed together with dozens of other high-quality studies in the world.
The KIHD has yielded close to 500 international, peer-reviewed original articles and more than 20 PhD theses. The project is expected to yield interesting results well into 2020's.
