Assessment of the Knowledge and Use of Ultrasound in Diagnosing Sarcopenia among Healthcare Workers in Southeast Nigeria

A bstract Background: Sarcopenia results in a reduction in function, falls, frailty, and increased morbidity and mortality. Healthcare workers’ knowledge and practice of preventive strategies will help reduce morbidities and mortalities. There is a paucity of research on sarcopenia in southeast Nigeria. Objectives: To assess the knowledge and use of ultrasound in diagnosing sarcopenia among healthcare workers in Enugu, southeast Nigeria. Materials and Methods: Structured and validated questionnaires were distributed randomly to healthcare professionals from October to December 2023. Questions included demographics, knowledge of sarcopenia, its risk factors, complications, awareness of the use of ultrasound for its diagnosis, radiologists’ knowledge of ultrasound features of sarcopenia, and its management. Data were analyzed using the Statistical Package for the Social Science (SPSS Inc), version 24.0. Results: A total of 375 valid questionnaires were included. The mean age is 36.0 ± 8.0 years. About 70.1% of respondents were unaware of the definition of sarcopenia. Age as a risk factor was correctly identified by 49.7%. Additionally, 34.5% of the respondents noted a reduced quality of life as a side effect. The knowledge of the use of ultrasound for sarcopenia diagnosis was 25% ( n = 94). Among radiologists, muscle thickness (38.1%) and echogenicity (33.3%) were indicated as accurate diagnostic ultrasound parameters and nutritional supplements intake to be the highest measure of treatment (32.4%), while 17.6% stated increased physical activity. Conclusion: Healthcare professionals in Enugu, Nigeria, were poorly informed about sarcopenia. We hope this study increases general awareness, emphasizes the need for training interventions for healthcare workers, and stimulates radiologists’ interest in ultrasound training to diagnose this preventable disease and improve the quality of life of the region’s aging population.
