Hazard ratio (HR) and 95% confidence interval (CI) for linear associations between physical activity volume and mortality in UK Biobank. Physical activity volume is derived using three assessment methods: physical activity energy expenditure predicted from self-report (PAEESR), International Physical Activity Questionnaire (IPAQ) scoring of MET-minutes/day, and sum of leisure-time physical activity and occupational physical activity MET-minutes/day (LTPA+OPA). All HRs per 1 standard deviation increment of exposure. Event-rate per 100,000 person years. Adjusted for age (as timescale), sex, ethnicity, Townsend deprivation index (baseline hazard stratification), highest educational level, employment status, alcohol drinking status (baseline hazard stratification), smoking status, salt added to food, oily fish intake, fruit and vegetable intake, processed and red meat intake, body mass index, parental history of cancer, parental history of [heart disease, stroke, hypertension or diabetes], use of blood pressure medication, use of cholesterol lowering medication, doctor-diagnosed diabetes or treatment with insulin.
