  1. Abbreviation: MVPA: Moderate to vigorous physical activity; MPA: moderate physical activity; VPA: vigorous physical activity; LIPA: light physical activity; BMI: body mass index; CVD: cardiovascular disease. NVQ National Vocational Qualification (NVQ) or HND Higher National Diploma (HND) or HNC Higher National Certificate (HNC) or equivalent = 19 years of education; CSEs Certificate of Secondary education (CSE) or equivalent = 10 years of education; O levels/GSCEs General Certificate of Secondary Education (GCSE) or equivalent = 10 years of education; A levels/AS levels or equivalent = 13 years of education; and College or University degree = 20 years of education. Tertiles were used to categorize low (3.1 to 10.1 h/day), medium (10.2 to 11.3 h/day) and high (≥ 11 h/day) sedentary time. We also used tertiles to categorize MVPA (0 to 21.2 min/day; 21.3 to 40.9 min/day; ≥41 min/day), LPA (0 to 70.2 min/day; 70.3 to 119.2 min/day; ≥119.3 min/day), MPA (0 to 19.1 min/day; 19.2 to 36.8 min/day; ≥36.9 min/day), and VPA (0 to 0.97 min/day; 0.98 to 2.9 min/day; ≥3 min/day)
