Abstract:

Objective To investigate the effect of a nutrition intervention program based on the Knowledge-Attitude-Practice（KAP） theory in breast cancer patients undergoing chemotherapy. Methods A convenience sampling method was adopted to select female patients with breast cancer receiving chemotherapy at a Grade Ⅲ Class A hospital in Gansu Province from October to December 2024 as participants. They were divided into intervention group and control group based on wards. The intervention group received KAP-based nutrition intervention，while the control group received conventional nutritional nursing education. Differences in weight，serum albumin，hemoglobin，KAP levels，and quality of life between the two groups after intervention were compared. Results A total of 48 patients and 50 patients were included in the intervention and control group，respectively. After intervention，the intervention group showed no significant change in weight （P>0.05），whereas the control group experienced a significant decrease（P<0.05）. The intervention group demonstrated significantly higher serum albumin levels，KAP scores，and quality of life scores compared to the control group（P<0.05）. Conclusion The KAP-based nutrition intervention program effectively maintains body weight，improves KAP levels，and enhances quality of life in breast cancer patients during chemotherapy. Further long-term follow-up studies are warranted to assess the intervention’s long-term impact on patients’ nutrition-related outcomes.
