The proportion of women and levels of fasting plasma glucose level (FPG), glycated hemoglobin (HbA1c), fasting serum insulin (FINS), homeostasis model assessment for insulin resistance (HOMA-IR), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-c) were greater among subjects with a first-degree FHD than those without an FHD (all P < 0.05). Here, INS is linked to Insulin resistance.
