Comparative Analysis Of Exposure To Risk Factors Of Stroke High-risk Population In Yantai From 2015 To 2019

Objective: To analyze the changes in stroke risk stratification and risk factors in high-risk groups,evaluate the effectiveness of community stroke prevention and control project,provide a basis for stroke screening and prevention in the Yantai area,and guide the future screening and prevention work,we analyzed the screening data of residents in the Yantai screening site(Dong ting street community health service center)of the National Health Commission screening and intervention project for stroke high-risk population from 2015 to 2019.Method: According to the screening criteria of stroke high-risk population screening and intervention project of the National Health Commission,We used the cluster sampling method to investigate the permanent residents over 40 years old at the screening sites in Yantai City in 2015,2017,and 2019.We used EXCEL、SPSS23.0 software to process and analyze the data.We compared the dynamic changes among the stroke screening population in Yantai from 2015 to 2019,such as two high-risk risk factors(previous stroke and previous TIA)and risk stratification,the risk factors in high-risk groups,and the age stratification of high-risk groups.Results: According to the requirements of different annual screening tasks,5,868,4,021,and 4,026 people were screened in 2015,2017,and 2019 respectively.After excluding people meeting the exclusion criteria,5,490 people(2,630 males and 2,860 females)were enrolled in 2015.3,955 people(1,694 males and 2,261 females)were enrolled in 2017;4024 people(1645 males and 2379 females)were enrolled in 2019.In 2015,the average age of the screening population was 60.28 years old,and that of the high-risk population was 63.89±9.156 years old.In 2017,the average age of the screening population was 63.14 years old,and that of the high-risk population was 65.76±8.537 years old.In 2019,the average age of the screening population was 64.22 years old,and that of the high-risk population was 66.05±8.962 years old.The average age of the high-risk population was significantly higher than that of the screening population in each year,with statistical significance(P<0.01).The age distribution of high-risk groups is as follows: 60-70 years old has the largest number,followed by 50-60 years old,70-80 years old,40-50 years old,and ≥80 years old has the least number.Comparison of risk factors between 2015 and 2017: The composition ratio of risk factors(hypertension,diabetes,atrial fibrillation or valvular heart disease,dyslipidemia,significant overweight or obesity)in 2017 was significantly higher than that in 2015,and the difference was statistically significant(P<0.01).The composition ratio of risk factors(family history of stroke,lack of exercise,and smoking history)in 2017 was significantly lower than that in 2015,and the difference was statistically significant(P<0.01).There was no significant difference in the composition ratio of risk factors(previous history of stroke,history of TIA,and gender)between 2015 and 2017(P>0.05).Comparison of risk factors between 2015 and 2019 in the high-risk population for stroke: The composition ratio of hypertension,diabetes,dyslipidemia,significant overweight or obesity,and previous TIA in the high-risk group for stroke screening in 2019 increased significantly,and the difference was statistically significant(P<0.01).In 2019,the composition ratio of atrial fibrillation or valvular heart disease(P<0.05),smoking history(P<0.01),lack of exercise(P<0.01),family history of stroke(P<0.01),previous stroke(P<0.05),and gender(P<0.01)were significantly reduced,and the difference was statistically significant.Comparison of risk factors between 2017 and 2019: The composition ratio of risk factors(dyslipidemia and lack of exercise)in 2019 was significantly higher than that in 2017,and the difference was statistically significant(P<0.01).The composition ratio of the previous TIA was also higher than that in 2017,the difference was statistically significant(P<0.05).The composition ratio of risk factors(atrial fibrillation or valvular heart disease,smoking history,family history of stroke)in 2019 was significantly lower than that in 2017,with statistical significance(P<0.01),and gender composition ratio was also lower than that in 2017,with statistical significance(P<0.05).There was no significant difference in the population composition ratio of risk factors(hypertension,diabetes,significant overweight or obesity,and previous stroke)(P>0.05).Conclusion: From 2015 to 2019,the detection rate of stroke in a high-risk population in Yantai increased gradually.The average age of the high-risk population was higher than that of the general population,and the high-risk population concentrated in 60-70 years old.Hypertension is the primary risk factor for stroke in the high-risk population in Yantai,and dyslipidemia,overweight or obesity,and diabetes are all elevated in the ranking of risk factors in the high-risk population.
