Knowledge, attitude, and practice toward nutrition support and management among hemodialysis patients

Nutrition support is an important care component for patients on hemodialysis. Also, patient self-management is important to maintaining proper nutritional intake during hemodialysis. This cross-sectional study investigated the knowledge, attitude, and practice (KAP) towards nutrition support and management among hemodialysis patients treated at the West China Hospital of Sichuan University between January and March 2023. Among 445 (95.91%) valid questionnaires, 58.43% were filled out by male patients. The knowledge, attitude, and practice scores were 11.44 ± 1.80 (possible range: 0-13), 30.29 ± 3.22 (possible range: 8-40), and 31.27 ± 5.67 (possible range: 8-40), respectively. Age > 60 years (OR = 0.487, 95%CI: 0.260-0.913, P = 0.025) and junior college or undergraduate or above (OR = 2.606, 95%CI: 1.621-4.189, P < 0.001) were independently associated with adequate knowledge. The knowledge (OR = 1.151, 95%CI: 1.024-1.294, P = 0.018) and female gender (OR = 0.632, 95%CI: 0.419-0.953, P = 0.029) were independently associated with positive attitude. The knowledge (OR = 1.404, 95%CI: 1.221-1.614, P < 0.001), attitude (OR = 1.146, 95%CI: 1.069-1.227, P < 0.001), age 51-60 years (OR = 1.879, 95%CI: 1.093-3.229, P = 0.022), and BMI of 24.0-27.9 kg/m² (OR = 0.434, 95%CI: 0.269-0.700, P = 0.001) were independently associated with proactive practice. Hemodialysis patients showed adequate knowledge, positive attitudes, and proactive practice; however, there were also several gaps in knowledge and misconceptions regarding proper nutritional self-management. Accordingly, addressing these gaps and misconceptions through carefully designed and effectively implemented education is crucial for providing comprehensive guidance on optimal nutrition and self-management strategies.
