A highly significant reduction in AAA prevalence was observed during 11 years in Norsjö. Treatment for hypertension and with statins was more frequent, whereas smoking habits remained low. This indicates that smoking is not the only driver behind AAA occurrence and that lifestyle changes and treatment of cardiovascular risk factors may play an equally important role in the observed recent decline in AAA prevalence.
