BACKGROUND: The North Karelia project, a community-based programme for prevention of cardiovascular diseases in North Karelia in 19721977, was successful in reducing some major cardiovascular risk factors. It was studied whether changes in the incidence of smoking- or diet-related cancers in North Karelia were different from those in a reference area without a programme.
METHODS: Poisson age-period-cohort-county regression models were fitted to each cancer-sex combination. Specially designed variables were added to the best models to detect any post-programme changes in the incidence trend in North Karelia.
RESULTS: After having been consistently higher, the incidence of lung cancer among males in North Karelia decreased below that of the reference county during 19871991. The programme-related risk ratio in 19871991 indicated a significant 20% beneficial effect. The trend in stomach cancer among males was more favourable in the reference county than in North Karelia.
CONCLUSION: The quicker reduction in smoking may have caused the more favourable trend of lung cancer among North Karelian males than males in the reference county.
