摘要
Abstract Purpose Sarcopenia is significantly prevalent among maintenance hemodialysis patients, with the contributing factors of medication literacy and polypharmacy receiving limited exploration in current research. This study aims to fill this gap by assessing the impact of these factors, along with demographic and malnurtition, on sarcopenia risk. Methods Conducted at the Wenjiang Hemodialysis Center in West China Hospital, this descriptive cross-sectional study involved 236 participants. Data collection included the Chinese Medication Literacy Scale, Malnutrition-Inflammation Score assessments, bioelectrical impedance analysis, and grip strength measurements, with sarcopenia diagnosed according to the 2019 AWGS criteria. Results The study included 236 participants. Of these, 87 (36.9%) had no sarcopenia, 121 (51.3%) were pre-sarcopenia, 7 (3.0%) were sarcopenia, and 21 (8.9%) had severe sarcopenia. Ordinal logistic regression analysis identified male gender (OR = 0.557, 95% CI: 0.322 to 0.962, P = 0.036), age below 65 (OR = 0.178, 95% CI: 0.082 to 0.389, P < 0.001), and good nutritional status (OR = 0.544, 95% CI: 0.310 to 0.954, P = 0.034) as protective against severe sarcopenia. Conversely, the combination of polypharmacy and limited medication literacy (OR = 1.956, 95% CI: 1.094 to 3.496, P = 0.024) was significantly associated with an increased risk of sarcopenia progression. Conclusion The study highlights the protective role of good nutrition and the lesser susceptibility of males and younger individuals to severe sarcopenia. It underscores the necessity of targeted interventions to address the compounded risk presented by polypharmacy and limited medication literacy in patients undergoing hemodialysis.
