Threshold values of anthropometric indicators of obesity for screening of low muscle mass in elderly women as a method for early diagnosis of sarcopenia

Abstract

The decrease in female sex hormones with age causes a decrease in muscle mass, a change in the contractile properties of muscles, as well as the infi ltration of adipose tissue into muscle. This leads to a subsequent decrease in muscle strength, functional disorders, and disability. In this regard, the development of simple screening techniques to detect low muscle mass is relevant.Aim of the study: to determine the threshold values of anthropometric obesity indices for detecting low muscle mass in elderly women.Materials and methods: the study included 593 elderly women (average age 63.19 ± 2.11 years). All participants were measured anthropometric indicators (height, weight, body mass index (BMI, kg/m2), waist circumference (WC), hip circumference (HC), the ratio of OT to height (OTR), triglyceride levels (TL), high density lipoproteins (HDL), body composition using bioimpedance analysis. Results:The study participants had a BMI of 28.49±5.17 kg/m2 and WC 95.35±10.39 cm, the prevalence of low muscle mass was 19.4%. The threshold values of anthropometric obesity indices for screening low muscle mass in elderly women for BMI were 29.4 kg/m2, for WC -94.3 cm, for WC/HC -0.91, for OTR -0.64, for IR -1.34, for . Logistic regression analysis showed that that age over 60 years (
