研究问题
To this end, it is necessary to identify whether there has been an absolute compression (a decrease in the years of unhealthy life) or expansion (an increase in the years of unhealthy life) of the conditions under analysis (multimorbidity, functional disability, and poor self-rated health).
方法
It analyzed a historical HLE series at age 60 from 2003 to 2019.；PNAD data on the health characteristics and physical mobility of residents aged 14 years and older are derived from the Health Supplement questionnaire (see Supplementary Figure 1).；PNS data are derived from the questionnaire’s Module K (health of individuals aged 60 years and older and mammography coverage among women aged 50 years and older), Module N (perception of health status), and Module Q (chronic diseases).The first edition of the PNS, specifically focused on health, was conducted in 2013 to refine and expand upon studies based on data from the PNAD Health Supplement (10, 19).
核心结论
This measure demonstrated high comparability, as the categories and question wording remained unchanged, thereby minimizing residual bias.；Their study on LE trends among the Chinese population between 1994 and 2015 demonstrated the positive impacts of China’s healthcare system reform, specifically improvements in the population’s cognitive and functional status.Schmidt et al.；However, a comparison between 2003 and 2019 revealed that the North region experienced the greatest increase in MFLE, demonstrating that population aging in this region is occurring rapidly and is accompanied by improvements in health.
局限
However, the concept of “being healthy” requires a multidimensional analysis that considers the complexity of the term “health” and its trends.；However, residual positive bias persists due to improved diagnostic identification in the PNS.The study also harmonized functional disability to ensure comparability by including only identical or corresponding BADL items across all surveys.；However, the PNS tends to yield higher prevalence rates of functional disability than the PNAD.The harmonization process applied to the health dimensions may have influenced the magnitude of the observed trends.
