BACKGROUND: China has been undergoing a rapid urbanisation. There are substantial disparities between old and new urban citizens in access to health care. We aimed to compare cardiovascular disease prevention and death risks among four distinct urban groups. METHODS: Urban residents aged 35-75 years living in 96 prefecture-level cities from 31 provinces in mainland China were enrolled in the national population-based cohort China Patient-centered Evaluative Assessment of Cardiac Events Million Persons Project. They were categorised into four groups by their former and current places of residence as follows: old-urban in situ residents (local residents in established urban areas since birth), new-urban in situ residents (local residents in newly urbanised areas established during urbanisation), urban-to-urban migrants (migrants from other urban areas), and rural-to-urban migrants (migrants from rural areas). We excluded participants with missing data for former and current places of residence, medical history, socioeconomic status, or lifestyle information. After adjusting for demographic and socioeconomic characteristics, relative risks (RRs) of cardiovascular disease prevention indicators and hazard ratios (HRs) of cardiovascular mortality and all-cause mortality of the other three population groups were estimated by modified log-Poisson models with robust standard error and Cox proportional hazard models, with old-urban in situ residents as the reference group.
