Validity of predicting the appendicular muscle mass by the mid-upper arm muscle area in obese elderly

Samenvatting

Rationale: Worldwide the number of obese elderly is increasing progressively, but weight loss could have an accelerative additive effect on loss of muscle mass. This study investigated to what extent the mid-upper arm muscle area predicts the appendicular muscle mass in obese elderly. Methods: Triceps skinfold and mid-upper arm circumference were measured at the baseline of the Muscle Preservation Study in 28 obese elderly (55+) from February till April 2011 to calculate the mid-upper arm muscle area. The results were compared to the appendicular muscle mass derived from the Dual-energy X-ray Absorptiometry, also measured at baseline. Results: In total there were 20 female subjects included for analysis. Mean TSF was 3.62cm (± sd 1.05), mean MUAC was 36.5cm (± sd 4.6) and mean MUAMA was 44.8cm2 (± sd 15.5). The found linear regression line showed that appendicular muscle mass (kg) = 0.105 * MUAMA (cm2) + 12.165, with a significant Pfor beta (P < 0.001). The proportion of explained variance was only 33.8%. Five subjects were identified as being sarcopene (SMI = 5.67kg/m2), and showed different MUAMA values (36.8cm2 ± sd 13.7 sarcopene vs. 47.5cm2 ± sd 15.5 non-sarcopene), which were not significant (P = 0.182). Sensitivity and specificity of two groups based on the MUAMA median and appendicular muscle mass median showed to be 70% for both, with minimal influence of the identified sarcopene subjects. Conclusion: MUAMA predicted the appendicular muscle mass (P < 0.001), but with moderate proportion of explained variance, which currently provides no conclusive evidence for extended use. In addition, the modest sensitivity and specificity for MUAMA and appendicular muscle mass and the low number of subjects included, require further research to make more solid statements about the extent of using MUAMA for predicting the appendicular muscle mass. Especially when taken into consideration the simplicity and low costs to extended implementation in practice.
