目的 调查医务人员肿瘤营养知识‐态度‐行为现状，并与既往进行对比，旨在观察状况变化，增强对营养治疗的重 视，并为进行有效的继续教育培训提供依据。方法 采用多中心、观察性研究，于 2018年 6 月至 2018 年 12月对 30个省（自治 区、直辖市）1972家医院6898名医务人员进行调查，并与本课题组2013年对全国医务人员肿瘤营养知识-态度-行为调查结果 进行比较分析。结果 调查对象医务人员营养知识得分（K分）（45.81±28.02）分，及格率 41.51%，优秀率 20.65%；营养态度得 分（A 分）（87.69±12.26）分，及格率 97.94%，优秀率 81.92%；营养行为得分（P 分）（75.04±16.34）分，及格率 85.41%，优秀率 46.49%。K分（P<0.01）及A分（P=0.034）在不同性别之间差异有统计学意义。K分（P<0.01）、A分（P<0.01）、P分（P<0.01）在不 同职业、职称、学历之间差异均有统计学意义，A分（P<0.01）、P分（P<0.01）在不同专业之间差异有统计学意义。获取营养知识 途径前3位为工作实践中学习、阅读有关书籍及期刊、毕业前在学校时学习。2018年医务人员营养知识得分（K分）、营养态度 得分（A 分）及营养行为得分（P分）均明显高于 2013年全国医务人员肿瘤营养知识-态度-行为调查结果（均 P＜0.01）。结论 全国医务人员的营养知识‐态度‐行为水平明显提高，总体营养知识‐态度‐行为现状明显好转，尤其在肿瘤营养治疗过程中仍有 着积极的态度和较好的营养治疗行为，但在营养知识掌握程度方面有待于进一步提高，依然是今后营养教育工作中的重点。

Objective Investigation on nutritional K⁃A⁃P of medical staff in the oncology in order to enhance the attention of medical staff to nutrition therapy and provide a basis for the effective education of nutrition. Methods From June 2018 to December 2018, 30 provinces (autonomous regions and municipalities directly under the central government)，1972 hospitals and 6898 medical personnel were investigated by multi⁃center and observational study, and the results were analyzed statistically and compared with the survey results of cancer nutrition knowledge, attitude and behavior of medical staff in China in 2013. Results The scores of nutrition knowledge (K), pass rate (41.51%), excellent rate (20.65%), nutrition attitude (A), pass rate (97.94%), excellent rate (81.92%), nutrition behavior (P), (75.04±16.34) score, pass rate (85.41%), excellence rate 46.49%. There were significant differences in nutritional K score (P<0.01) and nutritional A score (P=0.034) between different sexes. There were significant differences in nutrition K score (P<0.01), nutrition A score (P<0.01) and nutrition P score (P<0.01).There were significant differences in nutrition A score (P<0.01) and nutrition P score (P<0.01) among different specialties. The top 3 ways to acquire nutrition knowledge are working practice learning, reading related books and periodicals, and studying in school before graduation. The scores of K,A and P of medical staff in 2018 were significantly higher than those in 2013（all P<0.01）. Conclusion The level of nutrition knowledge⁃attitude⁃behavior of medical staff in China has been improved obviously, and the status of general nutrition knowledge⁃attitude⁃behavior has been improved obviously, especially in the process of tumor nutritional therapy, there are still positive attitude and good nutritional therapy behavior, but the degree of mastering nutritional knowledge needs to be further improved, which is still the focus of nutrition education in the future.
