Hypertension or medication: Systolic blood pressure ≥140 mmHg, or diastolic blood pressure ≥90 mmHg, or on medication for high blood pressure. History of elevated glucose: healthcare worker informed of an elevated glucose finding in the past
Leisure time physical activity daily: Vigorous- or moderate-intensity sports, fitness or recreational activities which resulted in increases in breathing or heart rate lasting for at least 10 minutes continuously on at least 5 days per week. Sitting time 6h or more/day: Based on question “How much time do you usually spend sitting or reclining on a typical day?”
