Risk factors of stroke in nine hospitals of six cities in Shandong,China:a case-control study
Objective To investigate the risk factors of stroke in nine hospitals of six cities of Shandong,and compare the differenc-es between residents of peninsula and inland areas.Methods Stroke patients in nine hospitals belonging to the Rehabilitation Medicine Alliance of Qilu Hospital of Shan-dong Universityfrom December,2022 to October,2023 were selected as the case group.The control group con-sisted of individuals undergoing health check-ups at the same hospitals during the same period.The sample size of both groups was equal,matched by age and gender,and demographic information and medical history were collected,and the risk factors of stroke were analyzed.Results A total of 438 cases were included.Residence in the inland(OR=2.07,95%CI 1.26 to 3.40,P=0.04),smoking(P=0.007),alcohol consumption(OR=6.67,95%CI 1.16 to 38.37,P=0.019),depression(OR=2.16,95%CI 1.03 to 4.53,P=0.042)and hypertension(OR=4.15,95%CI 2.34 to 7.39,P<0.001)were possible risk factors of stroke.However,smoking(OR=3.35,95%CI 1.11 to 10.10,P=0.013)and hypertension(OR=2.79,95%CI 1.12 to 6.95,P=0.004)were possible risk factors for the prevalence of stroke among residents in peninsula ar-eas,and obesity(excess waist circumference)(OR=1.08,95%CI 1.03 to 1.13,P=0.001),depression(OR=4.27,95%CI 1.38 to 13.23,P=0.013)and hypertension(OR=4.8,95%CI 2.21 to 10.43;P<0.001)were possi-ble risk factors for the prevalence of stroke among residents in the inland areas.Conclusion Hypertension is the most likely risk factor for stroke in nine hospitals of six cities of Shandong Province.Additionally,living inland,smoking and alcohol consumption may also increase the risk of stroke.There are dif-ferences in possible risk factors for stroke between peninsula and inland residents,and targeted stroke prevention and control measures should be implemented for different regions.
