Participants are stratified by sex and tertile (T) of BMI and WC; ** adjusted for age at 3HC, height, body mass index or waist circumference, social class (I, II, IIINM, IIIM, IV, V), physical activity level (active, moderately active, moderately inactive or inactive), prevalent myocardial infarction (yes, no) prevalent stroke (yes, no) prevalent cancer (yes, no), smoking status (current/ former, never), alcohol intake (units per week).; *only participants with complete data for all co-variables are included in analyses and analyses adjusted for age and height were also adjusted for either BMI or WC, as appropriate.
