Abstract 10957: Association of Insulin Resistance and Dysglycemia With Components of Blood Pressure: A Study From the Hispanic Community Health Study/Study of Latinos
2014
Background: Data are conflicting regarding the extent to which insulin resistance or dysglycemia contribute to the development of elevated blood pressure (BP). Therefore, we examined whether these metabolic abnormalities are associated with distinct BP components, including measures of pulsatile versus steady state load (surrogates for large and small artery disease) in a large community-based cohort. Methods: We studied 10,720 non-diabetic participants from 4 U.S. sites in the Hispanic Community Health Study / Study of Latinos who were free of cardiovascular disease and not on any anti-hypertensive medications. We used linear regression for complex survey sampling and non-parametric spline models to examine the relation of insulin resistance (HOMA-IR) and dysglycemia (HbA1c) with components of BP (systolic, diastolic, pulse pressure [PP, reflecting pulsatile load], and mean arterial pressure [MAP, reflecting steady state load]) while adjusting for established clinical correlates of BP. Results: The targe...
