Cohort Profile: The Polish-Norwegian Study (PONS) cohort

The PONS cohort is a longitudinal observational regional study collecting information on health and health-related behaviours in the south-eastern part of Poland. The study aims at providing information on determinants of health differences between Poland and other countries in the region, especially related to premature mortality. The baseline data collection contains records for 13 172 individuals (2010-11), between 45 and 64 years of age, from the city of Kielce and surrounding rural area. All cohort members were volunteer participants and gave informed consent prior to inclusion. Data were collected on current health status, medical history and health-related behaviours with focus on preventable causes of chronic diseases, including tobacco smoking, alcohol consumption, physical activity and dietary habits. In addition to an extensive questionnaire, blood and urine samples were collected for storage. The study is expected to provide valuable evidence related to various lifestyle behaviours and health, and insight into the usefulness of population approaches for preventive interventions in Polish communities.
