Hypertension prevalence among people lifted out of poverty in China: a retrospective spatiotemporal analysis (2018–2023)
ABSTRACT
Background:
Background:
Hypertension is a significant global public health concern, with considerable concern in China due to its widespread prevalence. The spatial distribution of hypertension varies significantly, revealing important regional disparities that may impact public health strategies and interventions.
Objective:
Objective:
This study aimed to investigate the temporal trends and spatial distribution characteristics of hypertension prevalence among individuals lifted out of poverty in China, covering the period from 2018 to 2023.
Methods:
Methods:
We utilized data from the National Health Poverty Alleviation Dynamic Management System to analyze the prevalence of hypertension among people lifted out of poverty from 2018 to 2023. Long-term trends were assessed using the JoinPoint regression model. Spatial distribution characteristics were examined through global and local spatial autocorrelation, cluster and outlier, and trend surface analyses. These methods provided insights into the spatial aggregation and variability of hypertension prevalence across different regions.
Results:
Results:
From 2018 to 2023, the prevalence of hypertension among individuals lifted out of poverty in China demonstrated a consistent upward trend. The highest prevalence was observed in the northeastern provinces. High-high aggregation areas were predominantly located in these northeastern provinces, while low-low aggregation areas were found in the western provinces. The prevalence of hypertension exhibited a pattern of decreasing and then increasing with both longitude and latitude, showing that it was notably higher in the northeast than that in the southwest.
Conclusions:
Conclusions:
The study revealed a generally increasing trend in hypertension prevalence among people lifted out of poverty in China from 2018 to 2023. The highest prevalence rates were concentrated in northeastern counties that have escaped poverty, while southwestern counties exhibited the lowest prevalence rates.
