Relation between risk of falls, sarcopenia and parameters assessing quality of skeletal muscles in a group of postmenopausal women.

introductionInvolutional changes that occur in skeletal muscle are a feature that characterizes the aging process. In women, age-related decreases in muscle mass and function of skeletal muscles occur more rapidly with the onset of menopause. Progressive muscle dysfunction has been directly linked with an increased probability of falls, fractures, disability and mortality. AIM OF THE STUDY: To assess the relationship between the risk of falls and parameters of skeletal muscle assessment in a group of postmenopausal women together with the identification of patients with sarcopenia. MATERIAL AND

methodsThis study was carried among 122 women over 60 years of age. Patients had their muscular system tested with the emphasis on the sarcopenia diagnosis using: Total Body Composition, handgrip and physical performance tests. Patients also underwent a questionnaire survey assessing occurrence of falls.

resultsThe analysis showed an over 2-fold increase (OR 2.4; 95% CI, 1.02-5.56) in risk of falls in a year among subjects with decreased muscle mass. No such correlation was noted with parameters such as falls in the last 12 months and decrease of muscle strength as well as physical performance. Sarcopenia is more likely to be diagnosed with European Working Group on Sarcopenia in Older People (EWGSOP1) criteria than EWGSOP2 (updated in 2018) (18% vs. 4.1% respectively). The increased risk of falls has not been proven in women with sarcopenia.

conclusionsThe decrease of muscle mass is significantly correlated with the risk of falls in the last year in postmenopausal women. Impact of sarcopenia on the risk of falls depends on diagnostic criteria.
