Resumo: | OBJECTIVE: The greatest cause of infant mortality in Brazil is perinatal conditions, mostly associated with preterm delivery. The objective of the study was to evaluate the evolution of preterm delivery rates in Brazil. METHODS: A review was conducted using the Medline and Lilacs databases, including published studies in periodicals, thesis and dissertations since 1950. Exclusion criteria were: studies related to clinical trials and those with complications at gestation and preterm delivery and care. Inclusion criteria were: population-based studies on prevalence of preterm delivery in Brazil, with representative sample of the studied population, and using primary data. Out of 71 studies found, analysis was carried out on 12. RESULTS: The prevalence of preterm delivery found ranged from 3.4% to 15.0% in the Southern and Southeastern regions between 1978 and 2004, with a rising trend from the 1990s onwards. Studies in the Northeastern region between 1984 and 1998 found prevalences of preterm delivery ranging from 3.8% to 10.2%, also with a rising trend. CONCLUSIONS: Data from the national live birth information system do not corroborate these trends. Rather, they show differences between the preterm rates given by this system and the rates measured in the studies included in this review. Because of the important role of preterm birth in relation to infant mortality in Brazil, it is important to identify the cause of these increases and to plan interventions that can diminish their occurrence. |

OBJETIVO: La mayor causa de mortalidad infantil en Brasil son las condiciones perinatales, asociadas en su mayoría a la prematuridad. El objetivo del estudio fue evaluar la evolución de las tasas de prematuridad en Brasil. MÉTODOS: Se realizó una revisión en las bases de datos Medline y Lilacs, incluyendo estudios publicados en periódicos, tesis y disertaciones, desde 1950. Los criterios de exclusión fueron: los estudios que se referían a temas clínicos, con complicaciones de la prematuridad y gestación, así como cuidados con prematuros. Los criterios de inclusión fueron: estudios de base poblacional sobre prevalencia de prematuridad con datos de Brasil, con muestra representativa del lugar de estudio y con datos primarios. De 71 estudios encontrados, el análisis fue realizado con 12. RESULTADOS: La prevalencia de prematuridad varió de 3,4% a 15,0% en las regiones Sur y Sureste, entre 1978 y 2004, sugiriendo tendencia creciente a partir de la década de 1990. Estudios en la región Noreste, entre 1984 y 1998, encontraron prevalencias de prematuridad de 3,8% a 10,2%, también con tendencia a aumentar. CONCLUSIONES: Los datos del Sistema de Informaciones de Nacidos Vivos no corroboran este aumento, ya que muestran diferencias entre las tasas de prematuridad informadas por ese Sistema y las tasas medidas en los estudios incluidos en esta revisión. Debido al importante papel de la prematuridad en la mortalidad infantil en Brasil es importante identificar las causas de este aumento y planificar intervenciones que disminuyan su ocurrencia. OBJETIVO: A maior causa de mortalidade infantil no Brasil são condições perinatais, associadas em sua maioria à prematuridade. O objetivo do estudo foi avaliar a evolução das taxas de prematuridade no Brasil. MÉTODOS: Foi realizada revisão nas bases de dados Medline e Lilacs, incluindo estudos publicados em periódicos, teses e dissertações, desde 1950. Os critérios de exclusão foram: estudos que se referiam a temas clínicos, com complicações da prematuridade e gestação, bem como cuidados com prematuros. Os critérios de inclusão foram: estudos de base populacional sobre prevalência de prematuridade com dados do Brasil, com amostra representativa do local do estudo e com dados primários. De 71 estudos encontrados, a análise foi realizada com 12. RESULTADOS: A prevalência de prematuridade variou de 3,4% a 15,0% nas regiões Sul e Sudeste, entre 1978 e 2004, sugerindo tendência crescente a partir da década de 1990. Estudos na região Nordeste, entre 1984 e 1998, encontraram prevalências de prematuridade de 3,8% a 10,2%, também com tendência a aumentar. CONCLUSÕES: Dados do Sistema de Informações de Nascidos Vivos não corroboram este aumento, pois mostram diferenças entre as taxas de prematuridade informadas por esse Sistema e as taxas medidas nos estudos incluídos nesta revisão. Devido ao importante papel da prematuridade na mortalidade infantil no Brasil é importante identificar as causas deste aumento e planejar intervenções que diminuam sua ocorrência.
