Certain elements of lifestyles (distinctive for the particular population) are presumed to influence on bone metabolism. This fact results in considerable differences between various populations, concerning both the occurrence of the normal variability of BMD (bone mineral content) among adult and elderly men and women, and also the prevalence of osteopenia or osteoporosis. The purpose of the study was to evaluate the variability of BMD in a group of healthy and occupationally active inhabitants of the city of Wroclaw, Poland (426 men aged 20-59 and 1218 women aged 20-62) and to compare our results with the reference ranges provided by the producer of the Stratec 960 apparatus. Trabecular and total BMD at the distal radius of the nondominant hand were assessed by peripheral Quantitative Computed Tomography (pQCT) using the Stratec 960 apparatus. BMD of Polish men and women significantly differ from the reference ranges of Stratec 960. The unfavourable phenomenon of the greater BMD decline with age, as compared to the standard values provided by the producer of the device, occurred. It should also be stressed that this reduction is more intense with age and it is marked among men older than 36. Taking into consideration the fact, that our material comprises only occupationally active subjects, the revealed differences would be probably greater, if they were evaluated in Polish population as a whole (our sample does not include persons, who are retired from the healthy conditions). Considering those significant discrepancies between our data and the Stratec reference population, one should be careful when using the normative database provided by Stratec for the densitometric diagnosis of osteoporosis among Polish women and men. Additionally the present study reveals that BMD (and its age-related changes during normal aging) is one of the features characteristic for the particular regional population, which is due to inter-populational differences of those elements of lifestyle, which can influence both general health condition and bone mineral density. |
