A High Aldosterone to Renin Ratio Is Associated With High Serum Parathyroid Hormone Concentrations in the General Population

Context: Activation of the renin-angiotensin-aldosterone system (RAAS) is associated with high serum PTH concentrations and vice versa. Objective: The aim of this study was to analyze the associations of the plasma aldosterone concentration (PAC), the plasma renin concentration (PRC), or the aldosterone to renin ratio (ARR) with serum PTH concentrations in a sample from the general population of northeast Germany. Design: We selected 3105 subjects (25–88 y) from the first 5-year follow-up examination of the Study of Health in Pomerania. The associations of PAC, PRC, or ARR with serum PTH concentrations were examined with multivariable linear regression analyses. We further calculated adjusted mean serum PTH concentrations according to PAC, PRC, and ARR categories (≥90th and < 90th sex specific percentiles and sex specific quartiles). The models were adjusted for age, sex, estimated glomerular filtration rate, serum 25-hydroxy vitamin D concentration, waist circumference, body mass index, hypertension, dia...
