Screening And Effect Evaluation Of Interventions In High Risk Population Of Cardiovascular Disease In Inner Mongolia

Objective This study was aimed to understand the level of risk factors of cardiovascular disease in Inner Mongolia Autonomous Region and evaluate the intervention effect in high risk population of cardiovascular disease.Method From 2016 to 2018,58861 permanent residents aged 35-75 years old in Inner Mongolia Autonomous Region were selected by stratified group to conduct the preliminary screening survey of cardiovascular disease high-risk population.And the high-risk objects were investigated by high-risk investigation,comprehensive intervention and follow-up investigation.In order to evaluate the effect of intervention,the change of high-risk population before and after intervention,which was conducted by China-PAR,was used.Multivariate logistic regression was used to analyze the influencing factors of intervention effect.Result(1)The main risk factors of cardiovascular disease include hypertension,dyslipidemia,diabetes,obesity and smoking.Among the investigated population,the detection rates of risk factors were 51.0%,31.5%,19.1%,67.3% and 25.5%,respectively.(2)The hypertension,dyslipidemia and diabetes rates were higher than those of women.The hypertension and diabetes rates increased with age.The overweight and obesity rates of Mongolian people was higher than those of Han nationality.The dyslipidemia and diabetes rates among urban residents and high-income people were higher.The hypertension rate among rural residents,low-cultural and low-income people was higher.(3)The detection rate of high risk group was 28.1%.(4)The proportion of hypertension decreased from 83.9% before intervention to 50.1% after intervention.The ratio of dyslipidemia decreased from45.8% before intervention to 40.3% after intervention.The proportion of diabetes decreased from 26.3% before intervention to 17.2% after intervention The proportion of overweight and obesity decreased from 77.1% before intervention to 67.9% after intervention.(5)The proportion of non-smoking increased from 77.3% before intervention to 83.3% after intervention.And the proportion of drinking more than 4times a week decreased from 6.2% before intervention to 3.3% after intervention.The proportion of physical exercise more than 1-3 times per month increased from 23.8%before intervention to 34.6% after intervention.(6)The intakes of coarse cereals,fresh vegetables,fresh fruits and bean products were less than that before the intervention.The intakes of meat and meat products and pickled vegetables decreased after the intervention.(7)The proportion of high risk population of cardiovascular disease decreased from 56.0% before intervention to 32.2% after intervention.The relative decline rate of high-risk population is higher for males than females,higher for Mongols than Hans,higher for urban than rural,lower with age,higher with education level and income level,the highest for workers of different occupations,followed by administrative career,the lowest for farmers.(8)The results of logistic regression analysis showed that with the increase of age,BMI,systolic blood pressure,total cholesterol,triglyceride,fasting blood glucose,the probability of better intervention was reduced.And the effect of male intervention was better than that of females,of urban intervention was better than that of rural,of adequate cereal and fruit intake was better than inadequate intake.Conclusion The risk of cardiovascular disease in our district was higher than the national average.The early screening and comprehensive intervention project of cardiovascular disease high risk population in Inner Mongolia Autonomous Region has achieved good intervention effect.
