Souza RT, Brasileiro M, Ong M, Delaney L, Vieira MC, Dias MAB, Pasupathy D, Cecatti JG. Investigation of stillbirths in Brazil: A systematic scoping review of the causes and related reporting processes in the past decade. Int J Gynaecol Obstet 2022; 161:711-725. [PMID: 36373189 DOI: 10.1002/ijgo.14573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 10/26/2022] [Accepted: 11/02/2022] [Indexed: 11/15/2022]
Abstract
BACKGROUND Recognizing the causes of stillbirths and their associated conditions is essential to reduce its occurrence. OBJECTIVE To describe information on stillbirths in Brazil during the past decade. SEARCH STRATEGY A literature search was performed from January 2010 to December 2020. SELECTION CRITERIA Original observational studies and clinical trials. DATA COLLECTION AND ANALYSIS Data were manually extracted to a spreadsheet and descriptive analysis was performed. RESULTS A total of 55 studies were included; 40 studies (72.2%) used the official data stored by national public health systems. Most articles aimed to estimate the rate and trends of stillbirth (60%) or their causes (55.4%). Among the 16 articles addressing the causes of death, 10 (62.5%) used the International Classification of Diseases; most of the articles only specified the main cause of death. Intrauterine hypoxia was the main cause reported (ranging from 14.3% to 54.9%). CONCLUSION Having a national system based on compulsory notification of stillbirths may not be sufficient to provide quality information on occurrence and, especially, causes of death. Further improvements of the attribution and registration of causes of deaths and the implementation of educational actions for improving reporting systems are advisable. Finally, expanding the investigation of contributing factors associated with stillbirths would create an opportunity for further development of prevention strategies in low- and middle-income countries such as Brazil.

CAD SAUDE PUBLICA 2021; 37:e00079120. [PMID: 33729304 DOI: 10.1590/0102-311x00079120] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Accepted: 07/28/2020] [Indexed: 11/22/2022] Open
Abstract
This study aimed to analyze the time trend in stillbirth rate (SBR) and the contribution by investigation to improving the definition of underlying cause of stillbirth in the city of São Paulo, Brazil, according to the place where the death certificate was issued. An ecological approach was used to analyze the trend in SBR by weight stratum (< 2,500g and ≥ 2,500g) and total deaths in the city in 2007-2017. Prais-Winsten generalized linear regression was used. The study of cases analyzed the underlying causes of stillbirth from 2012 to 2014, before and after the investigation, time of conclusion of the investigation, and redefinition of the underlying cause of stillbirths by type of issuer. In deaths with < 2,500g, there was an upward trend in SBR of 1.5% per year and a reduction (-1.3% per year) in stillbirths ≥ 2,500g. Total deaths presented a stable trend. In 2012-2014, 90% of deaths with ≥ 2,500g were investigated. After investigation, the underlying cause of death was redefined in 15% of the deaths, and not otherwise specified stillbirth (P95) represented 25% of the causes of death. The highest proportion of changes in the underlying cause of death occurred in deaths for which the death certificate was issued by the death certification review service (17%), while in health services the proportion was 10.6%. In conclusion, the SBR in deaths with ≥ 2,500g showed a downward trend. There was a significant redefinition of underlying causes, especially in those attested by the death certification review service. However, the redefinition was insufficient to expand the proportion of causes of death that would allow a better understanding of the mortality conditions.

Abstract
We reviewed the scientific production on maternal health and the health of children under ten years of age, published in Journal Ciência & Saúde Coletiva during the last 25 years, focusing on quantitative studies. The authors' characteristics, populations under study, thematic areas, and methodology are described. A total of 170 publications were identified and grouped into 12 major themes. Pregnancy, delivery, and puerperium were the subject of 47 studies, followed by child anthropometric assessments (29), breastfeeding (24), and mortality (13). The selected publications represented 3.5% of the total original papers published by the Journal since its creation in 1996 and about 5% of the publications in the 2015-2020 period. The primary data sources were health service records, information systems, and population surveys. The cross-sectional design was used in 113 of the 170 articles, and 70% covered only one municipality. The Southeast and Northeast Regions of Brazil were the target of most studies, and the North Region was the least represented. The publications reflect the complexity of maternal and child health themes, with a particular focus on the importance of the Unified Health System and showing how open access data can contribute to public health research.
