The aim of our study was to evaluate the anthropometric characteristics in postmenopausal women depending on appendicular skeletal mass.
Materials and methods: Weve examined 8882 women aged 2089 years (mean age 56.7±0.14 years; mean height 162.5±0.07 cm; mean weight 73.5±0.16 kg), among them anthropometric measures were performed in 79 postmenopausal women aged 4082 years (mean age 63.53±1.08 years, mean height 157.54±0.79 cm, mean weight 74.75±1.68 kg). Appendicular skeletal mass (ASM) was measured in all four limbs with DXA. We also calculated the appendicular skeletal mass index (ASMI) as ASM/height (kg/m2). During quartile analysis depending on ASMI the examined women were divided on following groups: Q1 ASMI <6.38 kg/m2 (n=20), Q2 ASMI =6.386.83 kg/m2 (n=20), Q3 ASMI =6.847.36 kg/m2 (n=20), Q4 ASMI >7.36 kg/m2 (n=19). 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 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%. During quartile analysis depending on ASMI we found that women of Q1 and Q2 groups had significantly lower the following anthropometric characteristics: weight (Q1 70.90 kg, Q2 70.25 kg, Q3 74.75 kg, Q4 85.53 kg; F=5.24; P=0.002), neck circumference (Q1 350 mm, Q2 357 mm, Q3 376 mm, Q4 393 mm; F=5.68; P=0001), abdomen circumference (Q1 846 mm, Q2 936 mm, Q3 1008 mm, Q4 1106 mm; F=11.52; P<0.0001), shoulder width (Q1 903 un., Q2 963 un., Q3 1029 un., Q4 1078 un.; F=2.22; P=0.09), narrow tibia circumference (Q1 221 mm, Q2 227 mm, Q3 244 mm, Q4 248 mm; F=6.44; P=0.0006). We also observed the significantly lower thorax circumference in women of Q1 group (Q1 903 mm, Q2 963 mm, Q3 1029 mm, Q4=−1079 mm; F=3.82; P=0.01) in comparison with women of Q4 group (Q1 903 mm, Q2 -963 mm, Q3 1029 mm, Q4 1079 mm; F=3.82; P=0.01).
Conclusion: Women with lower ASMI (Q1 and Q2 groups) had the significantly lower following anthropometric characteristics: weight, neck circumference, abdomen circumference, shoulder width, narrow tibia circumference. Thus, we can use the anthropometric measures for determining the groups with the relative risk of sarcopenia and its complications.
