Coeficiente padronizado de anos de vida perdidos, de Haenszel: comparação com o coeficiente padronizado de mortalidade geral, quanto à utilização como indicador de nível de saúde de populações Haenszel's standardized coefficient of lost years of life: a comparison with the standardized coefficient of general mortality with regard to its use as a health level indicator for populations

Abstract

Estudou-se o Coeficiente de Anos de Vida Perdidos (CAVP), proposto por Haenszel, em 1950, utilizando os dados populacionais confiáveis de países e das sub-regiões administrativas do Estado de São Paulo. Os resultados mostraram que: a) há conveniência em adotar 75 anos como idade limite, para o cálculo do CAVP, bem como intervalo de 10 anos para as classes etárias que se seguem às duas primeiras ( The Lost Years of Life Rate (LYLR), proposed by Haenszel in 1950, but since then seldom mentioned in literature, was studied. By using reliable populational data from various countries, and from regions of the State of S.Paulo, they showed that: a) It is convenient to employ 75 years as the age limit for the calculation of the LYLR, as well as a ten-year interval for the age classes that follow the first and second ones (less than 1, and 1 to 4); b) by comparing the ranking of countries and regions, in accordance with their LYLR and by the Standardized mortality rate (SMR), with the corresponding ranking using Novo's comprehensive Indicator (Z) as a parameter, they verified that the discrepancy was smaller in the first case; c) variations in time, of both coefficients, in the countries studied, calculated by the annual variation rate (AVR), were better expressed by LYLR than by SMR; d) using the Infant mortality rate (IMR) as a parameter, the discrepancies in the ordering of AYR, based on LYLR, were significantly smaller than those based on SMR. It was concluded that the LYLR can, with advantage, replace the SMR.
