ABSTRACT
An index that evaluates the health level of a population group considering both death and loss of function due to disease is called a summary measure of population health (SMPH). SMPHs are broadly divided into life year indices and life expectancy indices, the latter of which comprise healthy life expectancy (HLE). HLE is included as a policy target in various national and regional level healthcare plans, and the term "HLE" is commonly used in academia and by the public. However, the overall level of understanding of HLE-such as the precise definition of HLE and methods of calculating HLE-still seems to be low. As discussed in this study, the types of HLE are classified into disability-free life expectancy, disease-free life expectancy, quality-adjusted life expectancy, self-rated HLE, and disability-adjusted life expectancy. Their characteristics are examined to facilitate a correct understanding and appropriate utilization of HLE. In addition, the Sullivan method, as a representative method for calculating HLE, is presented in detail, and major issues in the process of calculating HLE, such as selection of the population group and age group, estimation of death probability, calculation of life years, and incorporation of health weights, are reviewed. This study will help researchers to select an appropriate HLE type and evaluate the validity of HLE research results, and it is expected to contribute to the vitalization of HLE research.

Objetivo: Estimar la esperanza de vida saludable para ambos sexos, y por delegación, y aportar algunos aspectos metodológicos para la construcción del indicador. Material y método: Con base en la información de mortalidad correspondiente al año 2000, se realizó el análisis de las defunciones y construcción de la tabla de vida de la población derechohabiente del Instituto Mexicano del Seguro Social (IMSS), con la finalidad de conocer la Esperanza de Vida (EV) de esa población, tanto nacional como por delegaciones, para ello se utilizó el método de Chiang. Posteriormente se realizó modificación a la tabla de vida ajustada por la prevalencia de discapacidad, a través del método de Sullivan, para el cálculo de años de vida libre de discapacidad. Resultados: Se calculó una esperanza de vida en población asegurada que fue de 77.4 años. La esperanza de vida saludable se estimó en promedio para la población derechohabiente en 65.8 años y la esperanza de vida con discapacidad en 10.5 años. Conclusión: La población asegurada muestra un perfil demográfico que aún esta en transición, ya que los estados del centro y sur del país aún muestran rezagos en materia de salud, que impactan en una menor esperanza de vida, y en la esperanza libre de discapacidad, a diferencia de los demás que ya se encuentran en transición avanzada. Esto refleja el perfil de salud y las demandas que el sistema de salud deberá de enfrentar en el futuro. La tabla de vida es una herramienta que puede ayudar a los tomadores de decisiones a apoyar la construcción de escenarios y facilitar las actividades de planeación estratégica.
Objective: Estimate the disability adjusted life years for both sex and state and include the methodology that let it to build the indicator. Material and methods: We shown the build of life table elaborated for the Mexican population with Social Security in order to know the life expectancy (LE). We made the Chiang's Method with information about population and death certificate for the year 2000 after we modified the table of life Sullivan's method. Results: We calculate the life expectancy in social security population in 77.36 years and the life expectancy free of disability around 65.8 years and life expectative with disability in 10.5 years, this reference is a population ageing in transition process. Conclusion: With health profile that will give upper demands to health system. This is a tool that can help to build scene and to give facilities for the strategic administration.
ABSTRACT
OBJECTIVES: To measure DALE (Disability-Adjusted Life Expectancy) in Korea to find out how long Koreans live in a state of full heath. METHODS: DALE was calculated using the life table of 1999 and the disability prevalence from the National Health Interview Survey (NHIS), which was conducted with a sample of 13,523 households in 1998. The disability prevalence was measured using the annual prevalence of the long-term limitation of activities, which were divided into classes 1, 2, 3, 4, 5 and 6 according to the severity of the limitation. The disability weights were measured for each 6 class by conducting a survey of 16 healthcare professionals. The severity-adjusted disability prevalence was calculated by multiplying the disability prevalence of each class by the disability weights respectively. Healthy life years lost due to disability was calculated by multiplying the life expectancy by the severity-adjusted disability prevalence. Finally DALE was measured as the life expectancy minus healthy life years lost due to disability. RESUJLTS: DALE for 1999, which refers to the expectation of equivalent years of good health, were 72.5, 69.5 and 75.3 years, for total, for males and for females, respectively. The percentages for DALE out of the life expectancy were 95.8, 96.6 and 94.4% for total, for males and for females, respectively. CONCLUSIONS: DALE is a newly developed indicator, which could effectively show the healthy life expectancy of populations. A greater notice and use of DALE would be expected as life expectancies increase and the quality of life changes in Korea.
