Bone Abstracts

The aim of the study was to evaluate the peculiarities of body composition in postmenopausal women depending on bone mineral density (BMD).

Materials and methods: We’ve examined 8882 women aged 20–89 years (mean age – 56.7±0.14 years; mean height – 162.5±0.07 cm; mean weight – 73.5±0.16 kg). Anthropometric measures were performed in 80 postmenopausal women aged 40–82 years (mean age – 63.53±1.08 years, mean height – 157.54±0.79 cm, mean weight – 74.75±1.68 kg), who were divided on the following groups depending on BMD: i) (N) – 32 women with normal BMD, ii) (OSN) – 28 women with osteopenia; iii) (OSP) – 20 women with osteoporosis. Anthropometric characteristics of the women were evaluated by the method of Bunak V.V. (1941) in the modification Shaparenko P.F. (1994). Lean and fat masses, BMD were measured by DXA using a densitometer Prodigy, GE. Statistical analysis was performed using the program ‘Statistica 6.0’.

Results: Frequency of sarcopenia in women aged 65 years and older was 7%. We found that women with osteoporosis had significantly lower the following anthropometric characteristics: weight (N – 81.50 kg, OSN – 72.5 kg, OSP – 69.4 kg; F=5.62; P=0.005), head circumference (N – 558 mm, OSN – 558 mm, OSP – 541 mm; F=4.59; P=0.01), circumference of the forearm widest part (N – 272 mm, OSN – 252 mm, OSP – 246 mm; F=9.41; P=0.0002), calf diameter (N – 110 un., OSN – 107 un., OSP – 98 un.; F=3.90; P=0.02), shoulder width (N – 89 un., OSN – 82 un., OSP – 80 un.; F=4.09; P=0.02), transverse diameter of the chest (N – 310 un., OSN – 292 un., OSP – 278 un.; F=4.69; P=0,01). Using DXA we observed that women with osteoporosis had significantly lower lean (N – 43382 g, OSN – 40042 g, OSP – 40702 g; F=3.73; P=0.03) and fat (N – 36826 g, OSN – 31160 g, OSP – 27323 g; F=6.03; P=0.004) masses.

Conclusion: We have found that women with osteoporosis had significantly lower anthropometric characteristics (weight, head circumference, circumference of the forearm widest part, calf diameter, shoulder width, transverse diameter of the chest) and lean and fat masses in comparison with women with normal BMD. Thus, we can use the received results for form the ‘anthropometric portrait’ of women suffering from osteoporosis and sarcopenia.
