Abstract

Summary

Possible sarcopenic obese women had a decreased likelihood of osteoporosis but an increased likelihood of fragility fractures compared with non-sarcopenic non-obese and sarcopenia-only women. Furthermore, possible sarcopenic obese women had lower values of trabecular bone score than non-sarcopenic non-obese and sarcopenia-only women.

Purpose

The coexistence of possible sarcopenia and obesity may have opposing effects on osteoporosis. This study aimed to investigate whether possible sarcopenic obesity is associated with osteoporosis or fragility fracture.

Methods

In this cross-sectional study of 1007 postmenopausal women from Taiwan, bone mineral density of the spine and hips was evaluated using dual-energy X-ray absorptiometry (DXA), and bone microarchitecture was evaluated using the trabecular bone score (TBS) derived from a lumbar spine image acquired by DXA. According to the definition of sarcopenia by the 2019 Asian Working Group for Sarcopenia, possible sarcopenia was defined by either low muscle strength or reduced physical performance. Obesity was defined as a body mass index of ≥ 27 kg/m2. Based on the presence of possible sarcopenia and obesity, study participants were classified as follows: control (non-sarcopenic non-obese), sarcopenic (non-obese), obese (non-sarcopenic), and sarcopenic obese. Prevalent fragility fractures were determined by retrospectively reviewing medical records.

Results

In this study, 10.1% of participants were classified as sarcopenic obese, 9.1% as obese, 35.2% as sarcopenic, and 45.6% as control. Relative to the control group, the sarcopenic obese group (OR, 0.28; 95% CI 0.18, 0.46) and obese group (OR, 0.38; 95% CI 0.23, 0.61) had a decreased likelihood of osteoporosis. However, the sarcopenic obese group (OR, 2.29; 95% CI 1.31, 4.00) and obese group (OR, 1.94; 95% CI 1.04, 3.62) had an increased likelihood of fragility fractures than with the control group. In addition, the sarcopenic obese group had a higher likelihood of fragility fractures than the sarcopenic group. Possible sarcopenic obese women also had significantly lower TBS values than those in the control and sarcopenic groups.

Conclusions

Possible sarcopenic obese women had a lower likelihood of osteoporosis but a higher likelihood of fragility fractures than non-sarcopenic non-obese and sarcopenia-only women. Furthermore, possible sarcopenic obese individuals had lower values of TBS than non-sarcopenic non-obese and sarcopenia-only women.
