Data Analysis Of High-risk Groups Of Stroke Screening In Rural Areas Of Six Provinces And Cities Of China

Purpose: The primary purpose of this study is to investigate the stroke prevalence and related risk factors through analysis of screening data for high-risk groups of stroke in rural areas of six provinces and cities of China aged 40 years and above, then to provide a scientific basis for the development of rural stroke prevention and control strategies in order to carry out stroke risk factors intervention.Method: The 384,272 cases used in this paper came from the national population health science data sharing platform of China stroke data center, which is the National Health and Health Committee of the new medical reform major project “Screening and prevention project of high-risk population in stroke" data resources from rural areas of six provinces and cities of China aged 40 years and above in 2012. To study the stroke prevalence , risk stratification and distribution of major risk factors in the rural areas of six provinces and cities of China.Result: 1. The stroke prevalence in the population: There were 8196 stroke patients in rural areas of six provinces and cities of China including Beijing, Henan province,Shandong province, Sichuan province, Shanxi province and Shaanxi province. The stroke prevalence was 2.13%, of which 4274 cases of male (2.39%), 3922 cases of female (1.95%). The detection rate of male is higher than that of female. The difference was statistically significant( P <0.001).2. Geographical Analysis of stroke prevalence: In this 384,272 cases of high-risk individuals of Beijing, Henan province, Shandong province, Sichuan province, Shanxi province and Shaanxi province, the highest stroke prevalence was 3.56% in Henan Province, 2.95% in Beijing, 2.73% in Shandong Province, 2.33% in Shanxi Province,1.29% in Shaanxi Province and 0.63% in Sichuan province. There were regional differences in the stroke prevalence of the screening population.3. Age analysis of stroke: Among the 8196 stroke patients, the number of stroke patients in the 40-64 age group was 4387 (53.53%). The detection rate of stroke increased with the growth of age. The detection rate of stroke in 55 years and above group increased to the level of stroke detection in the population. The detection rate of stroke in the people over age of 55 increased significantly. There was a significant difference in the stroke prevalence between different age groups (P <0.001).4. Risk assessment of stroke: Among the 384,272 cases in the rural population in the six provinces and cities, 27278 cases (72.33%) were low-risk individuals, 51,622 cases (13.43%) were middle-risk individuals, and 54,722 cases (14.24%) were high-risk individuals.5. Analysis of risk factors of stroke in population: The prevalence of stroke risk factors in people aged 40 years and above in rural areas of six provinces and clities of China was as follows: the prevalence of dyslipidemia was 38.47%, followed by smoking (21.49%), hypertension (20.77%), overweight or obesity (17.03%),insufficient physical exercise (16.64%), family history of stroke (7.00%), diabetes(4.08%) and atrial fibrillation or valvular heart disease (2.21%). The prevalence of stroke risk factors of male was as follows: Smoking (43.83%), dyslipidemia(37.44%), hypertension (18.46%), insufficient physical exercise (15.21%) and overweight or obesity (13.59%). The prevalence of stroke risk factors of female was as follows: dyslipidemia (39.37%), hypertension (22.78%) and overweight or obesity(20.02%). Male smoking exposure rate was significantly higher than female, but female have higher explore rate on high blood pressure, dyslipidemia, overweight or obesity, insufficient physical exercise, family history of stroke, diabetes and atrial fibrillation or valvular heart disease exposure rates. The difference was statistically significant (P<0.001).Conclusion 1. The detection rate of stroke patients aged 40 years and above in rural areas of China was 2.13%. The male detection rate (2.39%) was higher than that of female (1.95%).2. The detection rate of stroke in Henan Province was 3.56%, 2.95% in Beijing, 2.73%in Shandong Province, 2.33% in Shanxi Province, 1.29% in Shaanxi Province and 0.63% in Sichuan province.3. In rural stroke patients, the number of stroke patients in the 40 - 64 age group accounted for 53.53%. This situation seriously affects the health and quality of life of the rural labor force population. We should attach great importance to rural middle-aged stroke screening and prevention.4. Low-risk individuals in the screening crowd accounted for 72.33%, and moderate-risk individuals in the screening crowd accounted for 13.33%, high-risk individuals in the screening crowd accounted for 14.24% in rural areas of six provinces and cities of China of 40 years old and above.5. Dyslipidemia (38.47%) was the highest risk of stroke risk factor of stroke, followed by smoking, hypertension, obvious overweight or obesity and insufficient physical exercise.
