Introduction : Recent evidence suggests an interaction between bone metabolism and blood pressure (BP) regulation. The aim of our study was to evaluate endocrinological and metabolic factors related to pulse pressure (PP) in normotensive, normolipidaemic, non-smoker subjects.
Material and methods : We consecutively enrolled 156 adults (37 males, 119 females) in summer 2009. The BP and body mass index (BMI) were recorded, and serum samples were taken for 25-hydroxy vitamin D (25-OHD), insulin-like growth factor-1 (IGF-1), growth hormone (GH), parathormone (PTH), calcium, albumin, phosphorus, glucose, triglyceride and cholesterol levels.
Results : In the postmenopausal group, PP was significantly associated with age and BMI, while in premenopausal patients it was inversely related to ionized calcium. In men, a reverse relationship was present between GH and IGF-1 levels and PP.
Conclusions : The PP was predicted by different parameters in different genders and these predictors change even in the same gender before and after menopause. Well-known predictors of PP such as age and BMI were more pronounced in postmenopausal women, but none of the groups showed a relationship between PP and 25-OHD or PTH.
