ARISTIMUNO, Ana María; STRACCIA, Mabel Ofelia; ARIAS, Valeria Lorena  e  VENTIMIGLIA, Fernando Daniel. Evaluation of lipid levels and insulin resistance in pre- and postmenopausal women. Acta bioquím. clín. latinoam. [online]. 2016, vol.50, n.3, pp.445-452. ISSN 0325-2957.

The purpose of this study was to evaluate the relationship between lipid levels and insulin resistance parameters with age, menopausal status (MS) and body mass index (BMI) in pre- and postmenopausal women. This cross-sectional study included 89 women: 42 premenopausal (Pre) and 47 postmenopausal (Post). FSH, LH, estradiol and insulin were measured by MEIA. Total-cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and glucose were measured by conventional clinical chemistry methods. Small and dense LDL-C (sdLDL-C) was estimated by calculation. Post women showed higher values of TC (p<0.0001), LDL-C (p<0.0001), HDL-C (p=0.0283), TG (p=0.0014), sdLDL-C (p=0.0001), TC/HDL-C ratio (p=0.0016) and glucose (p=0.0048) than Pre. Insuline and TG/HDL-C ratio were not different between groups. Multiple regression analysis showed TC, LDL-C and HDL-C levels to be linearly and positively associated to age. Measured LDL-C, TG, TC/HDL-C ratio, sdLDL-C, glucose, insulin and TG/HDL-C ratio showed linear and positive relationship with BMI. HDL-C was negatively associated to IMC. Only sdLDL-C concentrations were associated positively to MS.
