  1. IQR, interquartile range; HDL, high-density lipoprotein; SD, standard deviation. Social class categories adapted from Erikson et al. [15]. Blood lipid values are presented in mmol/L. aLow HDL cholesterol < 1.04 mmol/L (< 40 mg/dL) for men and < 1.29 mmol/L (< 50 mg/dL) for women. bRaised triglycerides ≥1.7 mmol/L (≥150 mg/dL) or receiving cholesterol/triglycerides lowering medication. Triglycerides can be converted to mg/dL by multiplying with a factor 88.5. HDL cholesterol levels can be converted to mg/dL by multiplying with a factor 38.6
