Abstract EN
Background and Objectives.
Skeletal muscle and skeletal muscle indices in young adults from developing countries are sparse.
Indices and the corresponding cut-off points can be a reference for diagnoses of sarcopenia.
This study assessed skeletal muscle using dual-energy X-ray absorptiometry (DXA) in healthy male and female subjects aged 20–40 years and compared their appendicular skeletal muscle mass (ASM) and total-body skeletal muscle (TBSM) indices using certain cut-off points published in the literature.
Methods.
A sample of 216 healthy adults men and women from northwest Mexico was included.
Body composition was assessed by DXA and several published DXA-derived skeletal muscle indices were compared.
Results.
Both, ASM and TBSM were higher in men compared to the women group (23.0 ± 3.4 versus 15.9 ± 1.6 kg; P<0.05 and 26.5 ± 4.1 versus 16.9 ± 1.9 kg; P<0.05, resp.).
These differences were also valid for both indices.
When derived cut-off points were compared with the most reported indices, significant differences were found.
Interpretation and Conclusion.
Published cut-off points from Caucasians are higher than cut-off point derived in this sample of Mexican subjects.
The new DXA-derived cut-off points for ASM proposed herein may improve diagnoses of sarcopenia in the geriatric Mexican population.
