[Referred morbidity and the utilization of health services in Brazilian urban areas: methodology]. / Morbidade referida e utilização de serviços de saúde em localidades urbanas brasileiras: metodologia.

The reorganization of the Brazilian health system in the last few years has been based on the decentralization of the services and the integration of preventive and curative medicine, then creating new needs in term of the health information needed for health planning. The planning and administration of a regionalized and integrated health system calls for information about the population's morbidity profile, and the description of the pattern of the utilization of the health services, which can be obtained by means of household health surveys. The methodology utilized in a household health survey carried out in the Metropolitan Area of S. Paulo, Brazil, from July 1989 to June 1990, is described. This survey has some distinct methodological characteristics, such as the sampling process that defined the domains by age and sex, allowing an analysis of populational groups less well represented in the general population, as that of less than one year of age and that of aged people, as well as the use of the results of the latest Brazilian Census in 1991 for adjusting the sample.
