The utility of biochemical markers of bone metabolism has not been proven in the diagnosis of metabolic diseases of the bone tissue; however they are widely used as a tools for treatment 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 taken into consideration during clinical use. The aim of the study was to determine the reference values and evaluate the influence of environmental and anthropometric variables on biochemical markers of bone turnover for women from Lublin Region (Poland). Subjects of the study were 188 normal women aged 30-79, all residents of Lublin Region. Analysed markers of bone turnover were: osteocalcin (OC) and C-terminal cross-linking telopeptide of type I collagen (CTX-I), both assessed using ELISA method. All blood samples were taken and analyzed at the Clinical Chem. Laboratory and Patho-morphology Department at the Institute of Agricultural Medicine in Lublin. The lumbar spine (L2-L4) of all subjects was examined in a-p position using the dual X-ray absorptiometry-DXA (DPX-A LUNAR Corp.) at the Department of Metabolic and Degenerative Diseases of Bone Tissue of Institute of Agricultural Medicine in Lublin. Data pertaining to factors affecting bone tissue were collected using a specially prepared questionnaire. Serum levels of OC and CTX-I in women in every age range were different, generally increasing with age. Serum levels of OC and CTX-I in 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 interpreting laboratory measurements of biochemical markers of bone metabolism.

Introduction. A decreased serum high density lipoprotein-cholesterol (HDL-C) is a strong predictor of cardiovascular risk. However, total HDL is a very dynamic, changeable fraction, and does not perform the function of atherosclerosis markers. In the presented study, the pattern of serum lipids, including HDL-C subclasses (HDL2- and HDL3-cholesterol), in a middleaged Polish Lower Silesia population was defined. Materials and method. A group of 746 males and 1,298 females, aged 35–70, were investigated. All subjects were participants in the PURE study. Mean serum lipid levels were determined for groups selected on the basis of gender, age, cigarette smoking, drinking alcohol and place of residence (urban/rural area). The data were analyzed using STATISTICA 6.0 PL. Results. In multiple linear regression models, age was the most important independent and consistent predictor of total cholesterol (TC) and LDL cholesterol (LDL-C). The prevalence of low HDL-C (threshold 40 mg/dL in males, 50 mg/dL in females) was 16.5% for males and 22.6% for females. This gender-conditioned difference in the prevalence of low HDL-C was greater in rural (20.0% vs. 30.9%, respectively, in males and females) in comparison to urban (14.4% vs. 17.1%) areas. The lipid pattern was significantly worse in rural than in urban females. Female rural inhabitants showed higher triglycerides (TG) and lower HDL cholesterol (total and contained in subclasses HDL2 and HDL3). Simultaneously, a higher BMI, higher percent of smokers and drinkers and lower age of smoking female rural inhabitants in comparison to urban females were estimated. In the total population, cigarette smoking or drinking alcohol were associated with significant increases in TC, LDL-C and TG, also with decreased HDL-C (smoking) or HDL2-C (drinking). Two-way analysis of variance showed the existence of interaction between these risk factors in their influence on HDL-C and HDL3-C. Conclusion. In the middle-aged population of the Lower Silesian region in Poland the place of residence (urban/rural area) had a significant impact on the lipid pattern. This pattern is more atherogenic in rural women than in urban women.
