目的 了解肿瘤化疗患者照护者营养照护现状并探讨其影响因素，为医院制定科学有效的肿瘤患者营养照护方案提 供依据。 方法 分层抽样法抽取2021年6月至7月中国人民解放军空军军医大学第二附属医院322例肿瘤化疗患者照护者为研 究对象，采用自行设计并经信效度验证的营养照护问卷进行现场问卷调查。 结果 照护者营养照护知信行得分分别为（5.61±2.36） 分、（23.98±2.99）分、（17.08±4.90）分，及格率分别为13.88%、99.37%及53.31%。城镇照护者营养照护知信行均高于农村者（β=1.526、 1.002、1.585，P<0.01）；大专及以上学历照护者营养照护知信行均高于高中及以下学历者（β=0.971、0.870、1.280，P<0.05）；已婚照 护者的照护行为相对较差（β=⁃1.585，P<0.05）；照护知识来源于医护人员的营养照护行为较好（β=2.462，P<0.001）；照护知识来源 于电子媒体的照护者照护知识（β=0.736，P<0.05）和行为（β=1.180，P<0.05）均较好。 结论 肿瘤化疗患者照护者营养照护知识严 重缺乏，照护态度积极但行为有待提高；营养照护知信行状况受其家庭所在地、文化程度、婚姻状况及照护知识来源的影响，临床 应结合照护者不同特征制订肿瘤化疗患者营养照护方案，应将农村、文化程度高中及以下和已婚的照护者作为重点关注对象，并 且尽可能采用医护人员宣教和电子媒体宣教方式进行健康教育。

Objective To understand the status of nutritional care for the caregivers of cancer patients undergoing chemotherapy and explore its influencing factors,so as to provide evidence for the hospital to formulate scientific and effective nutritional care plan for cancer patients. Method A total of 322 caregivers of chemotherapy patients were recruited in the Second Affiliated Hospital of Air Force Military Medical University from June to July 2021 using a stratified sampling method.A self⁃designed nutritional care questionnaire verified by reliability and validity was used for field questionnaire survey. Result The scores of nutritional care knowledge,trust and practice were(5.61±2.36),(23.98±2.99),(17.08±4.90),and the pass rates were 13.88%,99.37% and 53.31%,respectively.The knowledge, trust and practice of nutritional care in urban caregivers were higher than those in rural areas(β=1.526、1.002、1.585，P<0.01);The knowledge, trust and practice of nutritional care of those with college degree or above were higher than others(β=0.971,0.870,1.280,P<0.05);The caregiver behavior of married caregivers was relatively poor(β=⁃1.585,P<0.05);Nursing knowledge derived from the nutritional care behavior of medical staff was better(β=2.462,P<0.001);Caregivers whose knowledge was derived from electronic media had care knowledge (β=0.736,P<0.05)and behavior(β=1.180,P<0.05)were all better. Conclusion The caregivers of cancer chemotherapy patients were seriously lacking in nutritional care knowledge.They have a positive attitude towards nutrition care but their behaviors need to be improved. Nutritional care knowledge, belief and practice status are affected by their family location, education level, marital status and sources of nursing knowledge. Clinically,nutrition care programs for cancer chemotherapy patients should be formulated in accordance with the different characteristics of caregivers.Caregivers rural areas,under high school education,and the married should be the focus of attention, and health education should be carried out by means of medical personnel and electronic media education as far as possible.
