Work, Lipids and Fibrinogen Study (WOLF)
The WOLF study investigated the relationship between work conditions, biological risk factors and coronary heart disease incidence. WOLF recruited employees aged 15 to 65 years from 60 companies across Stockholm, Västernorrland and Jämtland, Sweden. Participants were divided into two cohorts: WOLF-S, which included over 5,600 participants from Stockholm and WOLF-N, which comprised over 4,700 participants from Västernorrland and Jämtland. WOLF-S participants completed the baseline data collection in 1993 and were followed up in 2009 and 2011. WOLF-N participants completed baseline data collection in 1996 and were followed up in 2000, 2009 and 2011. The 2011 follow-up of both cohorts was conducted using administrative data linkage to healthcare and vital statistics databases in Sweden.
