目的 探讨置入静脉输液港（implantable venous access port，IVAP）的乳腺癌患者运动恐惧现状及其影响因素。 方法 2024年8月—12月，采用便利抽样法，选取在北京市某三级甲等医院甲状腺乳腺外科接受化疗且置入IVAP的乳腺癌患者作为调查对象，采用一般资料调查表、恐动症Tampa评分表、癌症患者输液港自我管理行为评估量表对其进行调查。 结果 194例置入IVAP的乳腺癌患者运动恐惧得分为（44.02±4.72）分，运动恐惧发生率为85.6%。多元线性回归分析结果显示，受教育程度为初中及以下、大专/本科（以“研究生”为参照），带IVAP时间为3~6个月（以“<3”个月为参照），有无锻炼习惯，对IVAP的了解程度为很了解（以“不了解”为参照），癌症患者输液港自我管理行为总得分是置入IVAP的乳腺癌患者运动恐惧的影响因素（P<0.05），共解释其运动恐惧水平66.6%的变异度。 结论 置入IVAP的乳腺癌患者运动恐惧发生率较高且影响因素多样，护理人员应重视对置入IVAP的乳腺癌患者运动恐惧的早期识别，采取有效措施以降低患者运动恐惧水平，提高其运动积极性，促进其康复。

Objective To investigate the current status and influencing factors of kinesiophobia in breast cancer patients with implantable venous access ports（IVAP）. Methods From August to December 2024，a convenience sampling method was used to recruit breast cancer patients undergoing chemotherapy with IVAP implantation in the Department of Thyroid and Breast Surgery of a Grade A Class Ⅲ hospital in Beijing. Participants were assessed by a General Information Questionnaire，the Tampa Scale of Kinesiophobia（TSK），and the Cancer Patients TIVAPs Self-Management Scale. Results The mean kinesiophobia score among 194 breast cancer patients with IVAP was （44.02±4.72），with an incidence rate of 85.6%. Multivariate linear regression analysis revealed that a number of factors significantly influenced kinesiophobia （P<0.05） including educational level （junior high school or below，and college/undergraduate，with “postgraduate” as the reference）；duration of IVAP application（3-6 months，with “<3 months” as the reference）；exercise habits；familiarity with IVAP （very familiar，with “unfamiliar” as the reference）；and self-management behavior level related to IVAP. These variables collectively explained 66.6% of the variance in kinesiophobia among the patients. Conclusion Breast cancer patients with IVAP exhibit a high incidence of kinesiophobia，influenced by multiple factors. Healthcare providers should prioritize early identification of kinesiophobia in this population and implement targeted interventions to reduce fear of movement，so as to enhance physical activity engagement and facilitate rehabilitation.
