Objective To investigate the status of cognitive impairment in elderly patients with hypertension in Anhui Province,and analyze the influencing factors.Methods A total of 3 391 elderly people over 60 years old were selected from Special Activities for the Elderly in Anhui Province by random cluster sampling.The prevalence of cogni-tive impairment in the elderly was assessed by Mini-mental State Examination screening questionnaire.The prevalence of hypertension in the elderly was obtained by face-to-face interview.The correlation between different lifestyles and cogni-tive impairment in elderly patients with hypertension was analyzed by multivariate regression analysis.Results A total of 1 879 patients with hypertension and 276 elderly patients with hypertension had cognitive impairment.The significant differences in the elderly patients with hypertension had cognitive impairment in different age stratifications(x2=137.241,P＜0.001).Age(OR=2.848,95％CI:2.282-3.555,P＜0.05),Depression status inventory(OR=2.750,95％CI:1.786-4.236,P＜0.05),insomnia(OR=2.141,95％CI:1.507-3.043,P＜0.05),activities of daily living(OR=5.252,95％CI:4.207-6.558,P＜0.05)and triglyceride(OR=1.153,95％CI:1.027-1.294,P=0.016)were risk factors for cognitive impairment in elderly patients with hypertension.The protective factors of cognitive impairment in elderly patients with hypertension were enjoying exercise(OR=0.399,95％CI:0.273-0.583,P＜0.05),often partici-pating in community activities(OR=0.498,95％CI:O.392-0.631,P＜0.05)for the elderly.Conclusions Aged,de-pressed state,regular exercise,participating in community activities,sleep time deficiency,activities of daily living and high triglycerides are the influential factors of cognitive impairment in elderly patients with hypertension.The influencing factors of early screening and intervention of cognitive dysfunction are helpful for the prevention of cognitive dysfunction in the elderly hypertension.
