[Certificates of live birth: analysis of completion in the city of Ribeirão Preto, São Paulo, Brazil].
The study aims to identify the frequency with which certificates of live birth are filled out and to analyze the data they provide. To gather the data, the authors used a model birth certificate filled out by research assistants based on information obtained from the reports on mothers and newborns. This information was then compared to data contained in the official birth certificates available in the Information Technology Division of the Municipal Health Department. The sample consisted of 911 certificates of live birth from July 1996 in the ten maternity wards of the city of Ribeirão Preto. Data analysis showed that frequency of completion of birth certificates differs by hospital, involving both physicians and administrative personnel. The authors identified a high level of agreement in the data, i.e., over 90% in 13 of 18 variables compared in the birth certificates and in half of the hospitals investigated. The disagreement occurred especially with respect to data on the number of children per mother, number of prenatal visits, mother's schooling, and father's name.
