Abstract
Summary What is already known on this topic? Healthy aging among Chinese older people has low prevalence. Some sociodemographic and lifestyle factors were shown to be associated with healthy aging. What is added by this report? The age-adjusted prevalence of healthy aging in the 6 provincial-level administrative divisions (PLADs) of China is 15.8 % in 2019. County-level factors, such as the prevalence of healthy communities in a county, as well as some sociodemographic variables and physical exercise, are potential factors of healthy aging. What are the implications for public health practice? These findings showed that more targeted actions, including generalizing healthy communities and individual-level interventions, may be of great importance for healthy aging.
Highlights
This study aimed to evaluate the prevalence of healthy aging as defined in Table 1 and its correlates among China’s elderly aged 65 years and over through the community-based Healthy Aging Evaluation Longitudinal Study in China (HAELS), which was conducted in 6 provincial-level administrative divisions (PLADs) in 2019
The prevalence of communities that satisfied criteria of being a “healthy community” at the county-level was significantly associated with healthy aging [odds ratio (OR): 1.20 per 10% increase in prevalence; 95% confidence interval: 1.05–1.38]
HAELS was initiated in 2019 in 6 PLADs (Beijing, Shandong, Jilin, Jiangxi, Ningxia, and Guangxi) and collected high-quality information from representative samples of elderly individuals aged 65 years and over to evaluate and monitor the trends of healthy aging. These 6 PLADs were selected based on economic development level; 2 counties or city districts were randomly sampled from each province or municipality, respectively; 2 towns or street districts were sampled from each county or city district, respectively, using multistage stratified probability-proportional-to-size (PPS) sampling; and within each town or street district, 2 villages or communities, respectively, were selected using the PPS sampling method

County-level information for the participants was collected including the total population aged 65 years and over, the gross domestic product (GDP) per capita, the implementation of long-term care insurance, the total number of villages/communities, and the prevalence of communities that were deemed
