Recurrence Status and Combined Risk Factors of Surviving Stroke Patients Aged Over 40 in Urban Areas
Abstract
Background Stroke has become the 3rd leading cause of death among urban residents in China, and the combined rate ofrisk factorssuch as hypertension, diabetes, and dyslipidemia is high among urban high-risk groups. Liaoning Province is a high incidence area of stroke in China, however, there are a few studies on the recurrence of stroke and its combined risk factors in the northern urban areas. Objective To explore the recurrence status of surviving stroke patients aged over 40 and its combined risk factors in urban areas of Liaoning Province, in orderto provide a theoretical basis for formulating effective secondary prevention strategies. Methods From September 2018 to December 2020, 6 349 permanent urban residents aged over 40 in Liaoyang, Dandong, Benxi, and Chaoyang Cities of Liaoning Province were selected according to the economic and regional distribution using stratified cluster random samplingand investigated. A total of 488 surviving stroke patients were included and their recurrence rate and associated risk factors were analyzed in this study. Results There were 244 males and 244 females among the 488 surviving stroke patients, the average age was (65.8±7.5) years old and the proportion of patients aged 60-69 was the largest (43.7%) ; There were 352 (72.1%) first-onset stroke patients, 136 (27.9%) recurrent stroke patients, and a recurrence rate of 27.9% among surviving stroke patients; The recurrence rates of male and female surviving stroke patients were 29.5% (72 cases) and 26.2% (64 cases) , respectively, and the difference was not statistically significant (χ2=0.652, P=0.419) . The recurrence rate of stroke among people aged 40-49, 50-59, 60-69, 70-79 and ≥80 years old was 4/11, 23.4% (22/94) , 25.4% (54/213) , 35.9% (47/131) and 23.1% (9/39) , respectively, there was no significant difference in recurrence rate between male and female surviving stroke patients in different age groups (P>0.05) .The current drinking rate of the relapsed patients was lower than that of the first-onset stroke patients, and the awareness rate of hypertension, dyslipidemia, the treatment rate of dyslipidemia, and the control rate of dyslipidemia were higher than those of the first-onset stroke patients, and the difference was statistically significant (P<0.05) . Conclusion The recurrence rate of surviving stroke patients aged over 40 in urban areas of Liaoning Province is high, and patients with recurrence have higher rates of smoking, physical inactivity, overweight or obesity, and poor control of combined risk factors such as hypertension and diabetes mellitus, which require comprehensive and effective secondary prevention measures to reduce the risk of recurrence, disability and death in stroke patients.
