Abstract
ObjectiveHealthy life expectancy (HLE), which combines life expectancy with health, is an essential comprehensive measure of life length and quality. This article aimed to systematically review the methods for defining and measuring HLE and describe application studies published, providing a reference for decision makers to select and develop methods suitable for China's conditions to measure HLE.
MethodsSeven Chinese and English literature databases were searched up to May 7, 2022, and several related reviews and bibliography were manually retrieved. Systematic reviews and empirical research were included concerning HLE indicators and measurement of HLE. Information including the study area, type of the study, study population, HLE index, measurement method, data sources, and results from application studies published in the last five years were extracted. The evolution of the definition of HLE, the scope of different indicators, the measurement scale of health, and measurement methods, were all collected. Results of the empirical research related to measurement methods of indicators were summarized. The study followed the scoping review framework and was written according to the PRISMA-ScR statement.
ResultsA total of 84 articles were included, including 13 reviews, 17 original studies related to HLE index definition, ten original studies related to index measurement, and 44 empirical studies conducted in the past five years. There were as many as 20 indicators related to HLE, and each scale had its emphasis. A total of ten methods measuring HLE were identified, which vary in the definition of health, whether using weight, and the data type. The most commonly used indicators in the past five years were disability-free life expectancy and HLE. For the method of HLE calculation, Sullivan's method was mainly used for cross-sectional data, and the multistate life table was mainly used for longitudinal data.
ConclusionsThere are various definitions and measurement methods of HLE, but none are suitable for all scenarios. To summarize the HLE concept, health evaluation techniques, measurement methods, and application studies published worldwide can provide a reference for the localization of HLE measurement in China.
