Abstract

Abstract Objective: to assess the precision on birth information at the Civil Registry and Sistema de Informações Sobre Nascidos Vivos (Sinasc) (Live Births Information System) in Minas Gerais with the purpose to analyze the most recent fecundity level and pattern on women and to assess the hypotheses on the fertility component for populational projections adopted by the Instituto Brasileiro de Geografia e Estatística (IBGE) (Brazilian Institute of Geography and Statistics) in the 2013 review. Methods: the estimation level of under registration at the Civil Registry and Sinasc was based on the comparison of number of births registered by these sources with the number of births obtained from an independent source, estimated by the Brass P/F technique with adaptation. Results: in 2010, the coverage on the Civil Registry and Sinasc was 96.0% and 95.0%, respectively. In the period of 2003 to 2015, both sources point to the same trend. From 2011, the total number of births was practically the same. The corrected Total Fertility Rate and The Specific Fertility Rates had a very similar level and pattern in the period of 2010 to 2015. Discrepancies in the fertility hypotheses were observed from the IBGE. Conclusions: from 2010, the births registered in both data sources were considered as good statistical quality in Minas Gerais and the hypotheses of the fertility level and pattern in the IBGE projections need to be revised.

Highlights

The results are divided into three parts: the under registration measurement level of the Civil Registry and Sistema de Informações sobre Nascidos Vivos (Sinasc), a comparison between the fertility level and structure calculated by the Civil Registry and Sinasc and the evolutional analysis of the fertility structure compared to the fertility component projections for the Instituto Brasileiro de Geografia e Estatística (IBGE) projections
The fertility level of women in Minas Gerais calculated from the original Brass technique (TFT (Total Fertility Rate) of 1.78 children per woman) is higher than the rate calculated with the application of the modified method (TFT of 1.59 children per woman)
Having the Taxa de Fecundidade Total (TFT) estimation calculated by the modified method as true, the results show an improvement in the enumeration of birth registrations at the Civil Registry and Sinasc

Summary

Introduction

“a profile of the live births according to the variables that are considered important from the epidemiological point of view, and many of these were registered in the Declaração de Óbito (DO) (Death Statement), obtaining specific coefficients on infant mortality.”[4]. The growing understanding of the public agents in various administrative spheres and the society in general on the importance of birth registration as a primary document to citizenship has driven a number of public policies on the subject. These various actions remains and other actions incorporated over the years, aiming the access for a quick public Civil Registry document.[6]
