Study of a calculation method for healthy life expectancy

Area of Science:

• Public Health
• Gerontology
• Biostatistics

Background:

• Assessing healthy life expectancy (HLE) is crucial for public health planning and understanding population aging.
• Existing HLE calculation methods may not be directly applicable to China's unique demographic and socioeconomic context.
• China's rapidly aging population necessitates a tailored approach to measure healthspan.

Purpose of the Study:

• To develop and apply a calculation method for healthy life expectancy (HLE) specifically designed for China's urban population.
• To analyze the determinants of HLE among urban residents in China using national survey data.
• To provide data-driven insights for improving public health policies related to aging and longevity in China.

Main Methods:

• Utilized data on urban residents' deaths and the 1993 national survey for health services and family health conditions.
• Employed a specific calculation methodology to determine healthy life expectancy (HLE) in the Chinese urban context.
• Analyzed HLE trends across different age groups, genders, and city sizes.

Main Results:

• The ratio of healthy life expectancy (HLE) to overall life expectancy declines with increasing age.
• Females exhibit a higher HLE compared to males.
• Urban residents in large cities have a lower HLE than those residing in medium and small cities.

Conclusions:

• The developed HLE calculation method is suitable for the Chinese context.
• Age, gender, and urbanicity are significant factors influencing healthy life expectancy in China.
• Findings highlight the need for targeted health interventions to improve healthspan, particularly for males and residents of large urban centers.
