Objectives: To estimate the burden of disease due to vaccinable diseases and the relative importance of these diseases in the health of the Spanish population aged less than 15 years old. Methods: Disease burden was measured in disability-adjusted life years (DALYs). DALYs were computed by adding years of life lost (YLL) to years lived with disability (YLD). The DALYs of the Spanish population aged less than 15 years old were estimated for 1999 and were stratified by diseases according to the classification system of the Global Burden of Disease (adapted to the aim of the study), age group and gender. Diseases included in the childhood vaccination schedule, varicella, and pneumococcal disease were targeted for this study. The sources used were: the national mortality register to compute YLL, the Epidemiologic Surveillance National Network, hospital discharge data (CMBD) and the scientific literature to compute YLD due to vaccinable diseases, and World Health Organization estimates (Euro-A) or, when these were lacking, morbidity hospital data (Hospital Morbidity Survey) to compute the YLD due to non-vaccinable diseases. Results: The burden of disease due to vaccinable diseases was 1.2% of global DALYS (the overall DALYs rate was 46,57/1,000 habitants): diseases included in the vaccination schedule represented 0.00% to 0.03%, depending on age groups, except meningococcal infection (between 0.5% and 3.3%). Pneumococcal meningitis represented 0.06% to 0.65% and varicella 0.00% to 0.15%, also depending on age groups. Conclusions: Disease burden due to vaccinable diseases is a good indicator of the health of the young population in Spain. This measure summarizes and combines information on mortality, morbidity and disability caused by diseases. The DALYs attributable to diseases included in the vaccination schedule demonstrate that immunization programs have achieved their goals.

Objetivos: Estimar la carga de enfermedad de las enfermedades inmunoprevenibles y describir su importancia relativa en la salud de la población infantil y juvenil española. Métodos: La unidad de medida es años de vida ajustados por discapacidad (AVAD). Los AVAD resultan de sumar las pérdidas de salud por muerte prematura (AVP) y las pérdidas de salud por discapacidad (AVD). Se ha estimado los AVAD de la población española menor de 15 años para 1999 desagregados por: enfermedades según el sistema de clasificación de Carga Global de Enfermedad (adaptada al objetivo del estudio), por grupos de edad y sexo. Las enfermedades objeto del estudio son las incluidas en calendario vacunal infantil, la varicela y la enfermedad neumocócica. Las fuentes consultadas son: para el cálculo de AVP, el registro de mortalidad nacional; para el cálculo de AVD de las enfermedades inmunoprevenibles, datos de la RENAVE, CMBD y fuentes bibliográficas, y para los AVD de las no inmunoprevenibles, inferencia de las estimaciones de la OMS (Euro-A) y, en su defecto, a partir de datos de incidencia de la EMH. Resultados: La tasa de AVAD global es de 46,57/1.000 habitantes, y las enfermedades objeto del estudio representan el 1,2% del total de la carga de enfermedad: las enfermedades incluidas en el calendario de vacunaciones representan, según el grupo de edad, entre el 0,00 y el 0,03%, excepto la infección meningocócica (entre el 0,5 y el 3,3%). La meningitis neumocócica representa el 0,06-0,65% y la varicela, el 0,00-0,15%, según el grupo de edad. Conclusiones: La carga de enfermedad es un buen indicador para definir la salud de la población infantojuvenil española, ya que es una medida «sintética» que integra información sobre mortalidad, morbilidad y discapacidad de las enfermedades. Los AVAD atribuibles a las enfermedades inmunoprevenibles incluidas en el calendario nos permiten afirmar que los programas de vacunación han conseguido su objetivo.

OBJETIVO: Calculou-se a carga de doença devida à mortalidade, os anos de vida perdidos por "morte prematura" (AVP), nos Estados do Rio Grande do Sul e Santa Catarina, comparando alguns resultados com o Brasil. MÉTODOS: Baseou-se nos anos de vida ajustados em função da incapacidade (AVAI), indicador que agrega mortalidade e morbidade em uma medida global. As populações de estudo foram os óbitos de residentes nos Estados em 1994 e no Brasil em 1993. RESULTADOS: Embora a maior carga por mortalidade seja imposta por causas ligadas a um estágio mais avançado da transição epidemiológica, tanto o Rio Grande do Sul como Santa Catarina, mas principalmente o Brasil, sofrem importante carga por doenças do subdesenvolvimento. As lesões representam o segundo grupo nos Estados e terceiro no Brasil. CONCLUSÃO: O indicador permite comparar agravos de alta e baixa letalidade, sendo instrumento útil na gestão e controle social das políticas e ações de saúde.

INTRODUCTION: The register of death by cause, sex and age groups of residents in 1994 in Rio Grande do Sul (RS) and Santa Catarina (SC), two Brazilian southern states, were studied to calculate the years of life lost (YLL), one of the two components that summarize disability adjusted life years (DALY), in RS, SC and Brazil. METHODS: The methodology employed is the same used in the Global Burden of Disease study to quantify the mortality component (YLL) of DALY in the world. RESULTS: The results show that the greatest proportion and rates caused by Group II (Noncommunicable diseases), linked with more advanced stages of the epidemiological transition, in RS, SC and Brazil. But in both states and especially in Brazil, Group I (Communicable, maternal, perinatal and nutritional conditions) causes an important proportion of YLL. The Group III (Injuries) was the second more important group in RS and SC and the third in Brazil. Road traffic accidents are particularly important in SC, where the intentional injury rate is half than the one in RS. The leading causes of YLL were road traffic accidents, ischemic heart disease and cerebrovascular disease in SC, and ischemic heart disease, cerebrovascular disease and road traffic accidents in RS. CONCLUSIONS: Death certification in the southern region of Brazil has a complete coverage and miscoded death proportion is small, providing a reliable mortality information. DALY allow comparing fatal and nonfatal health outcomes to determine the importance of different diseases and to establish health priorities. DALY are also an useful tool to identify disadvantaged groups, target health interventions and provide information for social control of resource allocation.
