Objective

To identify the incidence of hypertension, overweight/obesity in middle-aged population in China, and explore their impact on cardiovascular events.

From 2009 to 2010, 12 areas were sampled in China, and about 1 000 subjects aged 35 64 from each area were enrolled to collect the basic information, physical examination and blood tests were also performed. From 2016 to 2017, data from 8 835 subjects, who completed the 6 years follow-up, were analyzed.Blood pressure and body mass index(BMI) at both baseline and the follow-up, as well as incidence of hypertension, overweight and obesity, were calculated. Cox proportional hazard model was used to investigate the impacts of hypertension, overweight and obesity on cardiovascular events after adjusting confounders.

At the end of follow-up, both BMI and systolic and diastolic blood pressure increased significantly compared with the baseline levels (all P<0.001). The cumulative incidence of hypertension, overweight and obesity within 6 years was 39.3%(1 146/2 918), 11.5%(406/3 544) and 4.3%(302/7 025), respectively. Compared with subjects with both normal BMI and blood pressure, people with overweight, obesity, hypertension, overweight with hypertension, and obesity with hypertension faced significantly increased risk of cardiovascular disease (HRs(95%CIs) were 2.394(1.130-5.073), 3.341(1.454-7.674), 6.047(2.978-12.279), 5.808(2.924-11.539) and 8.716(4.391-17.302), respectively, allP<0.05), after adjusting for other confounders.

The incidence of overweight, obesity, and hypertension is high in middle-aged people in China. Overweight, obesity and hypertension are associated with significantly increased risk of cardiovascular events during the 6 years follow up.
