RESUMO
Se presenta la génesis de la Encuesta de Salud de Cataluña (2010-2014) con sus submuestras semestrales. Se detallan las características básicas de su diseño muestral polietápico. Entre las ventajas organizativas de esta nueva operación, en comparación con las anteriores, destacan la agilidad en la disponibilidad de datos y la capacidad de monitorización continuada de la población. Se señalan como beneficios la puntualidad en la obtención de indicadores y la posibilidad de introducir nuevos tópicos a través del cuestionario complementario, según las necesidades de información. Como limitación se apunta la mayor complejidad del diseño muestral y la falta de seguimiento longitudinal de la muestra. Se hace hincapié en la necesidad de utilizar ponderaciones adaptadas a las submuestras para el análisis estadístico que emplee microdatos, así como de acumular oleadas si se desea elevar el grado de desagregación del análisis, ya sea en el territorio o por subgrupos de población (AU)
This article presents the genesis of the Health Survey of Catalonia (Spain, 2010-2014) with its semiannual subsamples and explains the basic characteristics of its multistage sampling design. In comparison with previous surveys, the organizational advantages of this new statistical operation include rapid data availability and the ability to continuously monitor the population. The main benefits are timeliness in the production of indicators and the possibility of introducing new topics through the supplemental questionnaire as a function of needs. Limitations consist of the complexity of the sample design and the lack of longitudinal follow-up of the sample. Suitable sampling weights for each specific subsample are necessary for any statistical analysis of micro-data. Accuracy in the analysis of territorial disaggregation or population subgroups increases if annual samples are accumulated (AU)
