Why the study?
Are specific behavioural factors (type-A behaviour, health locus of control, sleep problems, alcohol consumption) associated with non-fatal myocardial infarction independently of traditional risk factors?
Are specific behavioural factors (type-A behaviour, health locus of control, sleep problems, alcohol consumption) associated with non-fatal myocardial infarction independently of traditional risk factors?
External health locus of control, sleep problems, and lower alcohol consumption are associated with non-fatal myocardial infarction independently of traditional biomedical risk factors.
