  1. 1. Physical activity and myocardial infarction Epidemiological studies on the association between various types of physical activity and the risk of myocardial infarction, including certain aspects of methodology

    Detta är en avhandling från Stockholm : Reproprint

    Författare :Eleonor Fransson; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; hypertension; blood lipids; plasma fibrinogen; myocardial infarction; body mass index; recall bias; Physical activity; hypertension; blood lipids; plasma fibrinogen; myocardial infarction; body mass index; recall bias;

    Sammanfattning : The aim of this thesis was to study the associations between physical activity during leisure time, occupational and household work, and established risk factors for cardiovascular disease, as well as the risk of acute myocardial infarction. Methodological aspects concerning the presence of recall bias in epidemiological case-control studies on physical activity and myocardial infarction were also considered. LÄS MER
