Objective: To investigate the association between sarcopenia and different anthropometric indicators, and identify the best indicator to discriminate sarcopenia in community-dwelling older adult women.
Method: Data from 173 older adult women (≥60 years), living in Lafaiete Coutinho, a small-sized city in northeastern Brazil, were analyzed. Sarcopenia was defined based on the European consensus on definition and diagnosis using three components: muscle mass, muscle strength and performance. The association between sarcopenia and anthropometric indicators (body mass index, corrected arm muscle area and calf perimeter) was tested using the binary logistic regression technique.
Results: The adjusted regression model indicated that all anthropometric indicators were inversely associated with sarcopenia, and an increase by one unit in body mass index, corrected arm muscle area or calf circumference decreased the probability of sarcopenia in older adult women by approximately 85%, 16% and 72%, respectively.
Conclusion: All the studied anthropometric indicators can be used as discriminators of sarcopenia in an older adult women population. To this end body mass index exhibited better sensitivity and calf circumference better specificity. The results of the study may improve nursing practice and that of other healthcare professionals, enabling sarcopenia screening in older adult women from simple and low-cost anthropometric indicators.
