Letter: Utility of the Visceral Adiposity Index and Hypertriglyceridemic Waist Phenotype for Predicting Incident Hypertension (Endocrinol Metab 2017;32:221-9, Mohsen Janghorbani et al.)

VAI and HTGW Phenotype and Hypertension Risk ulation.Previous studies have reported a high risk of diabetes development in subjects with the HTGW phenotype and a high risk of coronary artery calcification in subjects with a high baseline VAI [9].Therefore, I wonder if similar results would be observed in this study population.Second, I wonder if the authors thought of analyzing whether metabolically healthy obese (MHO) subjects were present in this study population [12].The debate about the existence of MHO individuals in various ethnic populations continues [13].It would be interesting if the authors analyzed the level of risk that MHO subjects had for developing diabetes or HTN, since this study population is at a high risk for diabetes.Lastly, I think the authors should interpret the results with caution, since this study population is already at a high risk for metabolic derangement and diabetes.I want to congratulate the authors on this beautiful work and expect to see in the future many excellent studies emerging from this well-structured Iranian cohort.
