Objective  To explore the detection rate of populations at high risk of cardiovascular disease (CVD) among residents and its influencing factors in Liaoning province for providing evidences to effective prevention and control of CVD.

  Methods  We conducted a survey among 35 – 75 years old residents selected with stratified multistage random sampling in 3 urban districts and 3 rural towns of Liaoning province between 2014 and 2017. The participants′ information on demography, education, income, smoking, alcohol drinking, history of hypertension, diabetes, CVD and medication relevant to the diseases were collected with a questionnaire interview; the participants′ height, weight, waist circumference were measured and their blood glucose, blood lipid, urinalysis, and lung function were detected.

  Results  Of the 138 554 participants surveyed, 36 435 (26.3%) were identified as the individuals at a high-risk of CVD and the male participants had a significantly lower ratio of the at high CVD risk compared to the female participants (25.8% vs. 26.7%, 16 111 vs. 20 324 in number) (χ² = 14.155, P < 0.001). Among the participants, the ratio of the individuals at a high-risk of CVD increased with the increment of their ages and the participants aged 65 – 75 had the highest ratio (39.4%). The results of logistic regression analysis revealed following influencing factors of being at a high-risk of CVD for the participants: gender, age, marital status, education, occupation, income, smoking, alcohol drinking, hypertension history, diabetes history, and all routine blood lipids indicators (except for triglyceride) (all P < 0.001).

  Conclusion  The detection rate of individuals at high risk of cardiovascular disease is relatively high among 35 – 75 years old urban and rural residents in Liaoning province and interventions on cardiovascular disease need to be promoted among the high-risk populations.
