Correcao de informacoes vitais: estimacao da mortalidade infantil, Brasil, 2000-2009

Abstract

OBJECTIVETo propose a simplified method of correcting vital information and estimating the coefficient of infant mortality in Brazil.METHODSVital data in the information systems on mortality and live births were corrected using correction factors, estimated based on events not reported to the Brazilian Ministry of Health and obtained by active search. This simplified method for correcting vital information for the period 2000-2009 for Brazil and its federal units establishes the level of adequacy of information on deaths and live births by calculating the overall coefficient of mortality standardized by age and the ratio between reported and expected live births, respectively, in each Brazilian municipality. By applying correction factors to the number of deaths and live births reported in each county, the vital statistics were corrected, making it possible to estimate the coefficient of infant mortality.RESULTSThe highest correction factors were related to infant deaths, reaching values higher than 7 for municipalities with very precarious mortality information. For deaths and live births, the correction factors exhibit a decreasing gradient as indicators of adequacy of the vital information improve. For the year 2008, the vital information corrected by the simplified method per state were similar to those obtained in the research of active search. Both the birth rate and the infant mortality rate decreased in the period in all Brazilian regions. In the Northeast, the annual rate of decline was 6.0%, the highest in Brazil (4.7%).CONCLUSIONSThe active search of deaths and births allowed correction factors to be calculated by level of adequacy of mortality information and live births. The simplified method proposed here allowed vital information to be corrected per state for the period 2000-2009 and the progress of the coefficient of infant mortality in Brazil, its regions and states to be assessed.

Tendência secular da mortalidade infantil, componentes etários e evitabilidade no Estado de São Paulo – 1996 a 2012

“…In Brazil, this proportion ranged from 71.4% in 1997 to 69.4% in 2006 1. Although the time intervals and the quality of information6 , 7 , 17 on the cause of death will not allow us the direct comparison of values, these data show that since 1996, most infant deaths were avoidable, both in São Paulo and throughout Brazil.…”

“…, 7 The highest IMR are in the North and Northeast and the lowest in the South and Southeast 57 For example, in 2008-2010, the IMR corrected by active search of vital statistics was 11.2‰ LB in Santa Catarina and 28.7‰ LB in Amapá 7…”

“…, 5 However, due to its territorial extent the country has a large variability in IMR and difficulty in producing accurate estimates of this indicator 67 The highest IMR are in the North and Northeast and the lowest in the South and Southeast 57 For example, in 2008-2010, the IMR corrected by active search of vital statistics was 11.2‰ LB in Santa Catarina and 28.7‰ LB in Amapá 7…”

Clinical-Epidemiological Profile of Hospitalised Patients in Paediatric Intensive Care Unit

“…Infant mortality has declined, though not uniformly, in different regions of Brazil 22,23 . A nationwide study indicated a reduction in mortality from pneumonia in children of less than 4 years of age, with greater reductions in the south and southeast regions, indicating remaining discrepancies among the different regions of Brazil 19 .…”

Infant mortality by color or race from Rondônia, Brazilian Amazon

“…To correct such deficiencies, some authors have developed alternative strategies, which include prior and critical analyzes about the quality of vital databases and indirect estimates, as well as the application of correction factors before calculating infant mortality 5 , 9 , c .…”
