Objective: To understand the levels of ideal cardiovascular health (ICVH) in our country, to analyze the relationship of ICVH with the cardio-cerebrovascular disease (CVDs), and to provide evidence for developing effective strategies for CVDs integrated health management among populations. Methods: A multi-stage cluster random sampling method was used to conduct questionnaire survey, physical examination and laboratory detection among 21815 permanent adult residents in 2 counties of Suqian City in 2019. The relationship between ICVH index score and disease progression were analyzed by trend Chi-square test, and the relationship between CVDs prevalence and the number and score of ICVH ideal indicators were analyzed by (adjusted) multivariate logistic regression. Results: The prevalence of CVDs was 45.7%. The ICVH scores were (8.6±2.24), and the majority of residents achieved the (3-4) index standards(57.5%). The highest ideal level of ICVH was tobacco control (80.9%) and the lowest was healthy diet (0.1%). Compared with low level of cardiovascular health(0-2 indexes reached target value), those with moderate level (3-4 indexes reached target value) and high level (5-7 indexes reached target value) were 38% and 69% less likely to develop CVDs, respectively [ORICVH8-9=0.62(0.58-0.66),ORICVH10-15=0.31(0.29-0.33)]. Conclusion: The CVDs burden of the key population in the investigation area is heavy, the ICVH level is not high, and the ICVH level is negatively correlated with CVDs risk. The comprehensive interventions on poor dietary behavior, obesity and hypertension were suggested to be strengthened.
