The Relationship between Serum 25(OH)D, PTH and Calculated HOMA-IR in Overweight Elderly Patients

Abstract

Background: Vitamin D deficiency or insufficiency was commonly found among adults and particularly overweight elderly patients. It's controversial on the physiological roles of vitamin D and parathyroid hormone (PTH) in metabolic diseases. We explored the relationship between serum 25-hydroxyvitamin D [25(OH)D], PTH and homeostasis model of assessment for insulin resistance index (HOMA-IR) in overweight elderly patients.
