PURPOSE: Breast cancer patients undergoing chemotherapy experience adverse reactions, which lead to poor nutritional status. The objective of this study was to explore the dietary practice of Chinese breast cancer patients undergoing chemotherapy and to analyse the influence of nutrition literacy, self-care self-efficacy and perceived social support on dietary practice. METHOD: A total of 295 participants from three hospitals in China were enrolled. The Dietary Nutritional Knowledge, Attitude and Practice Questionnaire; Nutrition Literacy Measurement Scale for Chinese Adults; Strategies Used by People to Promote Health and Perceived Social Support Scale were administered. Multiple linear regressions were used to identify influencing factors. RESULTS: The dietary practice of patients were generally satisfactory. Nutrition literacy (r = 0.460, p < 0.001), self-care self-efficacy (r = 0.513, p < 0.001) and perceived social support (r = 0.703, p < 0.001) were positively correlated with dietary practice. The main factors influencing participants' dietary practice were nutrition literacy, self-care self-efficacy, perceived social support, living environment, cancer stage, body mass index, chemotherapy cycle and average monthly household income (all p < 0.05).
