Abstract: 【Abstract】Objective To understand the current attitude to consume soy products in peritoneal dialysis (PD) patients. Methods A questionnaire survey of the knowledge about taking soy products was conducted among PD patients treated in the PD centers in two Chinese traditional medical hospitals. Results A total of 125 valid questionnaires were collected, and the effective response rate was 82.78% (125/151). In these respondents, 91.2% had heard of high- quality protein diets necessary for kidney disease patients; 94.4% had heard that kidney disease patients could not eat soy products; 90.4% indicated that the knowledge about soy
product food was obtained from doctors and nurses and also from internet, television, relatives and other patients; 77.6% ate soy products occasionally, 68% felt unsuitable to eat soy products, and 20% never ate soy products; 17.6% took soy products to partially or completely substitute their meat diet. Serum albumin was lower in 32% of the respondents, in which serum albumin level was statistically different between PD patients younger than 60 years old and those older than 60 years old (P=0.041). Conclusion Many patients in the two PD centers were in the shortage of correct knowledge about the consumption of soy products. Therefore, dietary education must be reinforced for PD patients.
