Altitudinal, Temporal and Spatial Distribution of Cardiovascular Disease Incidence in Four Western Provinces (Guizhou, Qinghai, Sichuan and Yunnan) of China, 2023–2024
By Zengwu Wang, Bo Zhong, Kui Ji and 11 others.
Abstract
Background
Western China, characterized by high altitude, hypoxia, cold climate, and large seasonal temperature variations, exhibits a high level of cardiovascular disease (CVD) incidence, yet the underlying environmental risk factors remain poorly understood.
Methods
CVD data were obtained from the national surveillance database managed by the National Center for Cardiovascular Diseases, China. Disease burden was assessed using incidence rate and age-standardized incidence rate (ASIR). Spatial autocorrelation was evaluated using Global Moran’s I, and a generalized linear model (GLM) was employed for multivariable analysis.
