Comparing longitudinal sarcopenia trends by definitions across men and women after hip fracture

Journal of the American Geriatrics Society Apr 06, 2020

Shaffer NC, Huang Y, Abraham DS, et al. - Researchers undertook this prospective observational analysis to evaluate longitudinal trends in sarcopenia prevalence over 12 months following hip fracture employing three distinct operational definitions including European Working Group on Sarcopenia in Older Persons (EWGSOP), International Working Group on Sarcopenia (IWGS), and Foundation for the National Institutes of Health (FNIH). In Baltimore Hip Studies seventh cohort, 82 men and 78 women, aged 65 years and older, with surgical repair of a nonpathological hip fracture were analyzed. The highest prevalence of sarcopenia was afforded by EWGSOP and IWGS, while FNIH afforded much lower prevalence for men and women. An excellent agreement between EWGSOP and IWGS definitions was noted for both men and women, and FNIH displayed poor agreement with them, supported by several statistical measures across first‐year follow‐up. Over time, a stable prevalence was shown in men by all definitions, while the prevalence in women by FNIH was identified to be the lowest at 2 months, significantly raised at 6 months, and continued to be higher at 12 months. For EWGSOP and IWGS vs FNIH, sarcopenia prevalence following fracture varied greatly. Overall, sarcopenia seemed not to be decreased over the year after hip fracture, irrespective of definition.
