Abbreviations: BP =  blood pressure; HDL =  High-density lipoprotein; HOMA %B =  Homeostasis Model Assessment steady state beta cell function, HOMA %S =  Homeostasis Model Assessment insulin sensitivity, OGTT =  oral glucose tolerance test; NIM =  not included in model; CVD =  cardiovascular disease.

P<0.05; **P<0.01; ***P<0.001. P values are two-sided.

Models were adjusted for socio-demographic, medical history and smoking, alcohol and dietary behaviour. Please see Table S1 for full list of covariates included in the model for each cardio-metabolic biomarker.
