In 2010, the American Heart Association (AHA) published a new concept “ideal cardiovascular health" (iCVH), which consisted of 4 behaviors (smoking, body mass index, physical activity, and diet) and 3 health factors (total cholesterol, blood pressure, and fasting plasma glucose). We aimed to explore socioeconomic inequalities in iCVH among Chinese enterprise employees.27,607 employees aged 18 to 60 years were selected from 45 enterprises in 12 provinces of China, using a multi-stage cluster sampling method. All the 7 iCVH metrics and socioeconomic status (SES) indicators - education and occupational class. The multilevel mixed-effects logistic model accounting for the clustering of the data was used to identify the SES differences in iCVH.Only 0.6% of participants met all 7 iCVH metrics. The women had a higher proportion of meeting ≥5 ideal health metrics compared with men (48.0% vs.12.4%, P < 0.001). The subjects with higher education and occupational class had a higher proportion of meeting ≥5 iCVH metrics than their counterparts (P < 0.001). After adjustment for age, sex, drinking, prior CVD, workplace type and affiliated medical institutions, compared with the employees at low educational level, the odds ratio (OR) of iCVH metrics for subjects with medium and high educational level were 1.17 (95%CI:1.07–1.28) and 1.50 (95%CI:1.35–1.68), respectively. Compared with blue-collar workers, the OR of iCVH metrics for white-collar workers were 1.18 (95%CI:1.07–1.29). The OR of iCVH behaviors for subjects with medium/high educational level were 1.15 (95%CI:1.05–1.26), 1.48 (95%CI:1.32–1.66), respectively, compared with low educational level ones.Higher SES was associated with an increasing prevalence of iCVH metrics, behaviors and factors.
