The Relationship Between Serum Parathyroid Hormone Level, Nutritional Status and Body Composition in Obese and none Obese Reproductive Age Women

Background and objective: Obese individuals are at high risk for developing endocrine and metabolie dysfunctions. Among the endocrine derangements of obesity is hyperparathyroidism, believed to promote weight gain in obese subjects. Therefore the aim of this cross sectional study was to investigate serum Parathyroid Hormone concentration and its relationship with body composition and nutritional status in obese and none obese women. Materials and Methods: 86 healthy reproductive age women (17-50 years) with no history of hepatic or renal disorders, Diabetes and Hypertension and no consumption of vitamin D and calcium supplements were participated in the study. They were separated into two experimental groups based on Body Mass Index: obese group with stage I and 2 obesity (BMI: 30-34.9 and 35-39.9 kg/m respectively) and none obese group with normal weight (BMI : 18.5-24.9 kg/mʹ). Body composition was analyzed by BIA (Bioelectrical Impedance Analyser) method. Serum PTH and alkaline phosphatase was measured by Enzyme linked immunoassay technique (ELISA) and Enzymatic method respectively. Serum Calcium and Phosphorous were measured colorirnetrically. Dietary energy and nutrient intakes were analyzed by NUTRITIONIST III Software. Results: Body composition and anthropometric parameters were significantly different between two groups (P
