Insulin resistance and blood pressure circadian variation in an obese hypertensive population.
2006
Insulin resistance (IR) is related to arterial hypertension and target organ damage. Hypertensive individuals exhibiting a diminished nocturnal blood pressure (BP) reduction (non-dippers) have an increased incidence of cardiovascular events. The association, however, of IR with BP circadian variation has not been evaluated so far. Therefore, this study examined 226 (116 male and 110 female) overweight and obese subjects (BMI > 27kg/m2) with newly diagnosed essential hypertension who underwent clinical and laboratory evaluation, including an oral glucose tolerance test and ambulatory BP measurement (ABPM). IR was estimated using the homeostasis model assessment (HOMA-IR). The population was grouped according to HOMA-IR values > 2.75 (insulin resistance type) or < 2.75 (insulin sensitive type). Results. No significant differences were observed between dippers (n = 137) and non-dippers (n = 89) with respect to age, gender, BMI, serum cholesterol, triglycerides, LDL-C, and HDL-C levels, nor smoking habits.
