[Health-adjusted life expectancy in residents in Guangzhou, 2010-2019]

Area of Science:

• Public Health
• Epidemiology
• Gerontology

Background:

• Life expectancy (LE) and health-adjusted life expectancy (HALE) are key indicators of population health.
• Understanding the spatiotemporal trends and disease burden is crucial for public health planning.

Purpose of the Study:

• To analyze the spatiotemporal distribution of LE and HALE in Guangzhou from 2010 to 2019.
• To quantify the impact of various diseases and sequelae on health-adjusted life expectancy.

Main Methods:

• Utilized cause-of-death surveillance data and Global Burden of Disease study data.
• Employed joinpoint log-linear regression to analyze temporal trends and spatial distribution.

Main Results:

• LE increased to 82.9 years and HALE to 75.6 years by 2019.
• Central urban areas exhibited higher LE and HALE than urban fringes.
• Non-communicable diseases were the primary cause of healthy life expectancy loss, followed by injuries.

Conclusions:

• Guangzhou residents experienced steady increases in LE and HALE from 2010-2019.
• Disparities in health quality exist between central urban areas and the urban fringe.
• Developing targeted health policies and resource allocation is essential to mitigate the burden of non-communicable diseases.
