目的 探讨基于自主决定理论的双重任务训练在老年糖尿病伴轻度认知障碍患者中的效果。方法 选取2019年1月—6月河南省某医院的老年糖尿病伴轻度认知障碍患者为研究对象,随机分为对照组（n=36）和试验组（n=37）。对照组采用常规护理干预,试验组实施基于自主决定理论的双重任务训练。比较两组干预前、干预后、干预后12周的血糖、糖化血红蛋白、认知水平、平衡功能以及日常生活能力。 结果 两组血糖、糖化血红蛋白、认知水平、平衡功能以及日常生活能力组间与时间均存在交互效应（P<0.05）,简单效应分析显示,两组除了患者躯体生活自理能力得分在干预后差异无统计学意义外（P>0.05）,试验组干预后、干预后12周的各项指标均优于对照组（P<0.05）。结论 基于自主决定理论的双重任务训练可更有效改善糖尿病伴轻度认知障碍患者的血糖水平,改善认知及平衡功能,提高日常活动能力。

Objective To explore the effects of physical-cognitive dual-task training based on self-determination theory in older diabetic patients with mild cognitive impairment. Methods From January to June 2019,older patients with diabetes combined with mild cognitive impairment in endocrinology wards of a general hospital in Henan province were assigned to the experimental group（n=37）and the control group（n=36）. Patients in the control group received routine nursing care,while on this basis,patients in the experimental group received the physical-cognitive dual-task training.The blood glucose,glycosylated hemoglobin,cognition level,balance function and daily living ability of the two groups before intervention,after intervention,and after 12 weeks of intervention were compared. Results There were interaction effects between the two groups regarding the blood glucose,glycosylated hemoglobin,cognitive level,balance function,and ability of daily living（P<0.05）. The simple effect analysis showed that there was no statistically significant difference in the physical self-care scores of patients between the two groups after intervention（P>0.05）. All the other outcomes of patients in the experimental group after intervention and after 12 weeks of intervention were better than those of the control group（P<0.05）. Conclusion Physical-cognitive dual-task training based on self-determination theory can effectively improve the blood glucose level,cognitive level,balance function and daily activity ability of older diabetic patients with mild cognitive impairment.
