ABSTRACT
Objective To evaluate the efficacy of stroke prevention project for screening community stroke population by analyzing the dynamic alteration of risk factors and the control levels for stroke in the Wanshoulu community from 2011 to 2017. Methods We retrospectively analyzed the database of the Wanshoulu community population of stroke screening in2011(n = 10 379),2013 (n = 2 364),2015 (n = 6 048) and 2017 (n = 3 497). The population in 2011 and 2013 were first screening population (covered rate reached 84. 7% in the population aged ≥40 years old), and the population in 2015 and 2017 were re-examination population. We analyzed the dynamic alteration in the proportion of eight risk factors of stroke (hypertension, diabetes, dyslipidemia, smoking, less physical exercise, atrial fibrillation, obesity, and family history), the awareness rate and the control rate of three risk factors(hypertension, diabetes, and dyslipidemia), and the risk categories of stroke from 2011 to 2017. Results Compared with the data in 2011 and 2013, the proportion of patients with six risk factors in 2015 and 2017, including hypertension(26.8% [1623/6 048], 27.2% [952/3 497] ta.30.9% [3 210/10 379], 33.7% [796/2 364]), atrial fibrillation (2.1% [124/6 048], 1.6% [57/3 497] vs. 6. 7% [691/10 379], 2.7% [64/2 364]), smoking (11.9% [718/6 048], 7. 7% [268/3 497] vs. 17. 8% [1 845/10 379], 14.5% [343/2 364]), dyslipidemia (15.3% [928/6 048], 15.0% [526/3 497] vs. 17. 5% [1814/10 379], 22.0[519/2 364]), less physical exercise (18.4% [1 112/6 048], 17. 1% [598/3 497] vs. 24. 1 % [2 497/10 379], 33.0% [780/2 364]), and obesity (12.7% [769/6 048], 5.4% [190/3 497] vs. 12.9% [1 337/10 379], 17.0% [403/2 364]), gradually decreased over the time(all P <0. 01). Meanwhile, the proportion of high-risk stroke population decreased (22. 9% [2 373/10 379], 19. 9% [470/2 364], 17. 9% [1 083/6 048], 17.0% [595/3 497]) in 2011, 2013, 2015 and 2017, respectively. χ2=158.331, P<0.01). Compared with that in 2011, the awareness rate and control rate of hypertension, diabetes mellitus, and dyslipidemia were all increased in 2017(all P<0.01). Conclusion Since the performance of stroke prevention project in 2011, the risk factors of stroke have been well controlled, and the proportion of high-risk stroke population has been decreasing.
