Next, there were significant correlations of BIA with triglycerides, HDL cholesterol (except with PA) and apolipoprotein A1 (except with PA), as well as of FM with both LDL cholesterol and apolipoprotein B. Fats in the blood have traditionally been associated with obesity [34], which was confirmed by BIA measurement and for some new atherosclerotic risk factors [35], such as apolipoprotein A1. This evidence concerns the gene APOB and obesity due to melanocortin 4 receptor deficiency.
