Possibilities of use bioelectrical impedance analysis as measuring technique in prevention of osteoporosis

Bioelectrical impendance analysis (BIA) and dual energy X-ray absorptiometry (DXA) are the two most common methods used for body composition analysis. The aim of this study was to investigate if there is a correlation between results of body analysis by BIA and results of DXA measurements at usual sites for diagnosis of osteoporosis. If the correlation is found than it could mean that BIA might be used to point the need for extra DXA measurements, and earlier diagnosis of osteoporosis. 27 young adults (11 males and 16 females) aged 19-23 years were measured by BIA instrument for body composition analysis, and by DXA instrument for BMD and BMC at the L1-L4 vertebrae of the lumbar spine postanteriorly and the proximal femur (“hip”). Correlation coefficients were calculated to examine linear relationship of results of two methods. Mineral content obtained by BIA correlates with BMC (result of DXA) at all three measured sites. When analyzed by sex, correlation was found only among female subjects, while in males there was no correlation. Correlation of other results of BIA and BMD or BMC (DXA) showed similar situation. T-scores correlated positively with results of BIA within the female subgroup of the sample. According to obtained results we cannot conclude that results of BIA body composition analysis could be indicative for problems in bone metabolism, or state of bone density and bone mineral content, although some correlations are present.
