Abstract：Objective To investigate the current status of nutritional literacy in patients with gastroesophageal reflux disease(GERD)and analyze its influencing factors,thereby providing a reference for clinical decision-making.Methods Using a multi-stage sampling method,160 GERD patients treated at a hospital in Sichuan from January 2021 to January 2025 were en-rolled.General Information Questionnaire,the Adult Nutrition Literacy Measurement Scale,the Perceived Social Support Scale(PSSS),and the Chronic Disease Self-Efficacy Scale(CDSES)were employed.Multiple linear regression analysis was used to explore factors influencing nutritional literacy in GERD patients.Results The total score on the Adult Nutrition Liter-acy Measurement Scale was 166.86±10.26,the total PSSS score was 55.24±1.42,and the total CDSES score was 38.45±1.28.Pearson correlation analysis showed that nutritional literacy was positively correlated with social support and self-efficacy(r=0.644 and r=0.236,respectively;all P<0.05).Significant differences in nutrition literacy total scores were observed across subgroups defined by age,education level,personal monthly income,place of residence,course of the disease,weekly symptom fre-quency,malnutrition status,dietary management,social support level,and self-efficacy level among these patients(P<0.05).Multi-ple linear regression analysis indicated that age,education level,personal monthly income,place of residence,dietary management,to-tal PSSS score,and total CDSES score were all significant predictors of the Adult Nutrition Literacy Measurement Scale total score(P<0.05),together explaining 66.90%of the total variance.Conclusion Nutritional literacy among GERD patients remains subop-timal and is affected by multiple factors.Clinical staff should pay attention to patients'nutritional literacy and provide targeted interven-tions based on the identified influencing factors to strengthen nutritional literacy.
