Abstract

Early identification of individuals with high risk is crucial to preventing cardiovascular disease (CVD). We aimed to determine the prevalence of high CVD risk in Inner Mongolia and to analyze the treatment of major risk factors among individuals with high CVD risk. We selected 70,380 participants aged 35–75 years in Inner Mongolia between 2015 and 2017 using multistage stratified sampling. All participants completed a questionnaire and their blood pressure, blood glucose and lipid levels, height, weight and waist circumference were measured. Participants without a history of CVD were defined as high CVD risk if the predicted 10-year risk for CVD exceeded 10%. We assessed rates of high CVD risk and the prevalence and treatment of major risk factors among individuals with high CVD risk. After excluding participants with previous CVD, 68,083 participants remained. The overall prevalence of high CVD risk was 24.96%. The age- and sex-standardized rate of high CVD risk was 22.92%. Among high-risk participants, the prevalence of risk factors was hypertension (91.9%), dyslipidemia (54.1%), obesity (34.6%), diabetes (27.6%), and smoking (24.5%); clustering of these risk factors was common. The percentage of high-risk individuals taking antihypertensive drugs was 45.94% in those with hypertension; 27.99% of those with diabetes took hypoglycemic drugs and only 5.01% of those with dyslipidemia took lipid-lowering drugs. Control rates of hypertension, diabetes, and dyslipidemia were 1.20%, 4.43%, and 2.78%, respectively. Therefore, the prevalence of high CVD risk was elevated in Inner Mongolia, and treatment and control rates were low.
