MI, myocardial infarction; LTPA, leisure time physical activity; SES, socioeconomic status; SOC, sense of coherence
aEstimates are derived from GEE analyses with LTPA as an ordinal outcome (classified as regular, irregular, or none).
Model 1: Adjusted for age, sex, ethnicity, education, relative income, pre-MI employment, and living with a steady partner.
Model 2: Model 1 plus hypertension, diabetes, dyslipidemia, smoking, obesity, pre-MI leisure time physical activity, Killip class, Q-wave MI, anterior MI, Charlson comorbidity index, and self-rated health.
Model 3: Model 2 plus depression
