Description:

WOLF is a study that started in Stockholm in 1993. The acronym WOLF stands for Work-Lipids-Fibrinogen. The study is a collaboration between the former Working Environment Institute, the Institute of Environmental Health and the Institute of Psychosocial Environmental Health at Karolinska Institute and the Institute of Social Medicine in Sundbyberg.
WOLF makes up a collaboration program with the included partial projects WOLF-Stockholm, WOLF-Norrland and WOLF-F (The importance of work organisation and psychosocial strain factors to stress related poor health, five year follow up of WOLF-Norrland).
Main question formulation: Mental work load (stress) and indications for chronic cardiovascular disease. This original and general program idea has been developed and detailed in the partial projects WOLF-Stockholm (WOLF-S), WOLF-Norrland (WOLF-N) and WOLF-F (the five year follow up of WOLF-N).

Description:

In 2009, all participants who previously responded to a WOLF-questionnaire were asked to fill in a follow-up questionnaire (WOLF-U). The survey included questions about work environment, lifestyle and health. The response was positive and about 6 500 people answered the survey. The follow up did not include a health examination.
