目的 了解老年糖尿病患者社会疏离感现状并探讨其影响因素。 方法 采用便利抽样，于2020年9月至2021年10月选取广州市某三级甲等医院收治的358例老年糖尿病患者作为研究对象，采用一般资料问卷、一般疏离感量表、一般自我效能感量表和家庭关怀度指数量表对其进行调查。结果 老年糖尿病患者社会疏离感得分（41.27±6.60）分；多元线性回归分析结果发现，性别、居住地、糖尿病病程、自我效能感总分、家庭关怀度总分进入回归方程，可预测老年糖尿病患者社会疏离感48.6%的总变异。结论 老年糖尿病患者社会疏离感处于中等偏高水平；医护人员要特别关注男性、农村和病程<1年的患者，采取措施提高患者的自我效能感和家庭关怀度，从而降低患者的社会疏离感水平。
