The utility of biochemical markers of bone metabolism has not been provenin the diagnosis of metabolic diseases of the bone tissue; however they are widely used as a tools fortreatment monitoring. Their serum concentrations are influenced by a number of factors, like gender,health status, anthropometric and environmental factors. All the factors listed above should be takeninto consideration during clinical use. The aim of the study was to determine the reference values andevaluate the influence of environmental and anthropometric variables on biochemical markers of bone turnoverfor women from Lublin Region (Poland). Subjects of the study were 188 normal women aged 30-79, all residentsof Lublin Region. Analysed markers of bone turnover were: osteocalcin (OC) and C-terminal cross-linkingtelopeptide of type I collagen (CTX-I), both assessed using ELISA method. All blood samples were takenand analyzed at the Clinical Chem. Laboratory and Patho-morphology Department at the Institute of AgriculturalMedicine in Lublin. The lumbar spine (L2-L4) of all subjects was examined in a-p position using the dualX-ray absorptiometry-DXA (DPX-A LUNAR Corp.) at the Department of Metabolic and Degenerative Diseasesof Bone Tissue of Institute of Agricultural Medicine in Lublin. Data pertaining to factors affectingbone tissue were collected using a specially prepared questionnaire. Serum levels of OC and CTX-I inwomen in every age range were different, generally increasing with age. Serum levels of OC and CTX-Iin the analysed population strongly depended of both menopausal status and bone mineral density. In conclusion,this study demonstrates that age and menopausal status variations need to be considered when interpretinglaboratory measurements of biochemical markers of bone metabolism.
