Rural residence in China is linked to a ~2-fold steeper rise in heart disease mortality.
Why the study?
The burden of heart disease is increasing rapidly in China with unclear national mortality trends and urban-rural differences over time.
Observational
Answers are grounded in this paper and cite their sources.
May warrant targeted rural CVD prevention in China; leaves open socioeconomic drivers and requires prospective confirmation.
What is already known about this topic?: The burden of heart disease is increasing rapidly due to the aging population and changing lifestyles in China. What is added by this report?: This study investigated the evolution of mortality rates due to heart disease in urban and rural areas of China over the past 35 years, and identified the age-period-cohort effects on mortality changes. What are the implications for public health practice?: Healthcare providers should prioritize attention to heart disease among older males living in rural areas.

Su et al. (2023) conducted an observational in Heart disease. Rural vs urban residence and time period vs. Urban residents and historical periods was evaluated on Trends in crude and age-standardized mortality rates for heart disease. Rural residence in China was associated with a steeper 2.11-fold increase in crude heart disease mortality from 1987 to 2021 compared to a 1.78-fold increase in urban areas, disproportionately affecting older males.
