This cross-sectional study used population and inpatient databases to estimate mortality, life expectancy, and health-adjusted life expectancy in Shaanxi Province from 2015 to 2019.
The study used a cross-sectional design to analyze population, mortality, and health-related quality of life data from Shaanxi Province for the years 2015 to 2019. Methods included calculating age-specific mortality rates from a Full Population Database and prevalence rates from inpatient records, with adjustments for missing data and elderly mortality. Life expectancy was derived via life tables, and health-adjusted life expectancy (HALE) was estimated using the Sullivan method. Results showed a continuous population increase, improved mortality for children under five, and a decrease in mortality for those over 65. Life expectancy rose from 74.66 to 77.19 years. Limitations include potential mortality rate overestimation due to incomplete early death data, and HALE bias from reliance on inpatient records which may miss asymptomatic illness.
