Lipoprotein Particles in Adolescents and Young Women With PCOS Provide Insights Into Their Cardiovascular Risk

Context: Adult women with polycystic ovarian syndrome (PCOS) have an increased risk for cardiovascular disease, but the evidence for this is controversial in adolescents and young women with PCOS. Measurement of low-density lipoprotein (LDL) particle number, measured by nuclear magnetic resonance spectroscopy is a novel technology to assess cardiovascular risk. Objective: The objective of the study was to evaluate lipoprotein particle number and size in young women with PCOS and its relationship with insulin resistance and hyperandrogenism. Design: This was a cross-sectional case control study. Setting: The study was conducted at a clinical research center. Participants: Women with PCOS (n = 35) and normal controls (n = 20) participated in the study. Interventions: Blood samples and anthropometric measures were obtained. Main Outcome Measures: LDL particle size and number were measured using nuclear magnetic resonance spectroscopy. A secondary outcome was to investigate the correlation of LDL particle num...
