Insulin resistance in women's health: why it matters and how to identify itLegro, Richard SCurrent Opinion in Obstetrics and Gynecology: August 2009 - Volume 21 - Issue 4 - p 301–305 doi: 10.1097/GCO.0b013e32832e07d5 Reproductive endocrinology: Edited by David L. Olive Buy Abstract Author InformationAuthors Article MetricsMetrics Purpose of review To examine the significance of insulin resistance in women's health and review methods for diagnosing it. Recent findings Clinical phenotypes in conjunction with standard clinical biochemical assays, that is, the metabolic syndrome, remain the key method to diagnose insulin resistance in clinical practice. Candidate alleles from type 2 diabetes offer little predictive value for cardiovascular events beyond traditional risk factors. Simple environmental factors such as irregular meal frequency appear to increase the risk of the metabolic syndrome and require greater scrutiny. Pregnancy complications, particularly gestational diabetes and preeclampsia in the mother and preterm birth in the fetus are events that suggest elevated risk for future cardiovascular morbidity in those affected. Summary Clinical phenotypes of insulin resistance identify women at risk for perinatal and reproductive complications.
