Resumen
Se describen los procedimientos y se presentan algunos resultados del "estudio longitudinal de mortalidad de adultos costarricenses" (ELMAC), consistente en una muestra de cerca de 20.000 costarricenses de 30 o más años de edad del censo de población de 1984 seguidos hasta fines de 2007. El Instituto Nacional de Estadística y Censos (INEC) digitalizó los nombres de la boleta censal de los individuos en la muestra. Procesos informáticos depuraron los nombres y los enlazaron al número único de identificación -el número de cédula- del Registro Civil. El empate se efectuó en el 87% de la muestra. Los individuos identificados se siguieron en las bases de datos del Registro Civil para establecer su sobrevivencia. Se identificaron más de 5.000 defunciones entre el censo de 1984 y diciembre de 2007. Procesos informáticos adicionales enlazaron 92% de estas defunciones con las de las estadísticas vitales del INEC que contienen el dato de la causa de defunción. El patrón de mortalidad de la muestra, que comprende 373.000 personas-años de observación, reproduce bien las tasas de las tablas de mortalidad del país. Las gradientes socioeconómicas de la mortalidad en esta muestra no son sensibles a posibles errores en los empates o en las imputaciones efectuadas. La muestra confirma la excepcionalmente baja mortalidad de los adultos costarricenses, especialmente de los varones. Esta muestra abre la puerta para que se efectúen variedad de análisis de los determinantes socioeconómicos de la mortalidad de adultos en Costa Rica, algo rara vez intentado en un país en desarrollo.
We describe the procedures and show some results of the "longitudinal mortality study of Costa Rican adults 1984-2007" (ELMAC), which consists of a sample of about 20,000 Costa Ricans aged 30 years or more from the 1984 population census and a follow up of their survival status to December 2007. The National Institute of Censuses and Statistics (INEC) digitized the names from the census questionnaire for the individuals in the sample. Computer programs cleaned up name's errors data and linked them to the civil registration system to have the unique id-number that all Costa Ricans have since their birth-cédula number. The linkage was possible for 87% of the sample. Those individuals linked to cédula number were followed up in the computer databases of the Civil Register to establish survival or to identify deaths. More than 5,000 deaths were found between the 1984 census and December 2007. Additional computer programs linked 92% of these deaths with those in the INEC's Vital Statistics, which are the only one containing information on the cause of death. The mortality pattern in the sample, which comprises 373,000 person-years of observation, replicated nicely the rates in preexisting life tables for Costa Rica. The SES gradients in mortality in the sample are not sensitive to the imputations and assumptions made in the linkage and follow up processes. The sample confirms the exceptionally low mortality of Costa Rican adults, especially males. This sample opens up the door for further analyses of the SES determinants of adult mortality in Costa Rica, something rarely done in a developing country.
