ABSTRACT
The study attempts at estimating the sex-ratio at birth in Nigeria. The study focuses on demographic surveys with complete maternity histories, including some 0.50 million births. It compares results with published estimates from births in health facilities and a few data from vital registration, including some 1.13 million births. Results from demographic surveys give an estimate of about 106 boys for 100 girls. There were no significant variations by large region in the country, and no significant trend over the years (1990-2018). Published estimates provided a similar value (106.2), with somewhat lower value in health facilities (105.3), and somewhat higher values in local vital registration (106.8), and major variations among available studies. Despite uncertainty, Nigeria appears to have higher sex-ratios than most African countries, with the exception of Ethiopia, and higher values than its five neighboring countries. Reasons for these high values of the secondary sex-ratio are discussed. (Afr J Reprod Health 2022; 26[4]: 92-97).

Resumo Introdução A qualidade das informações dos Registros Hospitalares de Câncer (RHC) necessita de avaliação quanto à cobertura, completitude e concordância da causa básica(CB) com o Sistema de Informações sobre Mortalidade (SIM). Objetivo Avaliar a qualidade dos RHC nas duas unidades hospitalares do Instituto Mário Penna: Hospitais Mário Penna (HMP) e Luxemburgo (HL), Belo Horizonte, Minas Gerais, em 2016 e 2017, nos atributos mencionados. Método Por captura-recaptura (RHC x RHC), avaliaram-se, por unidade, cobertura, completitude da variável "óbito por câncer" e concordância da a (CB) com a causa da pesquisa (CP). Por relacionamento determinístico (RHC x SIM) avaliaram-se cobertura e concordância da CB. Resultados A cobertura dos RHC foi boa eexcelente (88,8% e 95,3%); a completitude foi ruim (34,6% e 32,6%) no HMP e HL respectivamente; por capítulo da CID-10, não houve concordância da CB com a CP. Observaram-se excelentes cobertura (94,7%) e concordância (94,5%) entre CP e SIM; observou-se sub-registro de 38 neoplasias no SIM, com reclassificação de causas pouco úteis. Conclusão A aplicação das técnicas de captura-recaptura e relacionamento determinístico contribuiu para a melhora da qualidade da informação dos RHC, com redução da incompletude nos RHC e correção da CB nos RHC e no SIM.
Abstract Bakground The quality of information from the Hospital Cancer Records (HRC) needs to be evaluated regarding coverage, completeness and agreement between the underlying cause (UC) as registered in the HRC and the Mortality Information System (SIM). Objective To assess the quality of the HRC in the two Instituto Mário Penna hospitals: Mário Penna (HMP) and Luxemburgo (HL) in Belo Horizonte, Minas Gerais, between 2016-2017. Method By capture-recapture (RHC x RHC), we assessed coverage, completeness of the "cancer death" variable and agreement between underlying cause (UC) with the cause of the research (CR), in each hospital. Deterministic relationship (RHC x SIM) was used to asses UC coverage and agreement between systems. Results The coverage of deaths at the HRC was good/excellent (88.8% and 95.3%); completeness was poor (34.6% and 32.6%) in HMP and HL respectively; per ICD-10 chapter, there was no agreement between CB and CP. Excellent coverage (94.7%) and agreement (94.5%) of CR and SIM were observed; 38 neoplasms were under-reported in the SIM, with reclassification of less useful causes. Conclusion Applying capture-recapture and deterministic linkage techniques contributed in improving the quality of information in the HRC, with a reduction in incompleteness in the HRC and correction of the UC in both HRC and SIM.
ABSTRACT
Background & objectives: In many developing countries including India, the civil registration data are incomplete, inadequate and not timely, therefore, compromising the usefulness of these data. The completeness of registration of death (CoRD) in the Indian Civil Registration System (CRS) was assessed from 2005 to 2015 at State level to understand its current status and trends over time and also to identify gaps in data to improve CRS data quality. Methods: CoRD for each year for each State was calculated from the CRS reports for 2005-2015. Data were analyzed nationally by geographic region and individual State. The availability of CoRD by age group and sex was also reported. Results: About 40 per cent increase in CoRD was documented for India between 2005 and 2015, with CoRD of 76.6 per cent in 2015. CoRD was >90 per cent in the western and southern regions and the eastern, central and northeastern regions had CoRD lower than the Indian average in 2015. Among the 29 States, 16 (55.2%) State had CoRD >80 per cent and five (17.2%) <50 per cent and 10 States recorded 100 per cent CoRD. Despite the highest per cent increase during 2005-2015 (108.5%), CoRD in Uttar Pradesh was 44.2 per cent in 2015. Varying levels of progress in 2015 were seen between the State with similar CoRD estimates in 2015. Nagaland (?63.3%), Manipur (?33.1%) and Tripura (?30.3%) were the only States that documented a decrease in CoRD during 2005-2015. The age non-availability for India ranged from 37.0 per cent in 2009 to 37.9 per cent in 2015, an average of 41.5 per cent over the seven years and was an average of 35.6 and 36.6 per cent for males and females, respectively. Age was available for all registered deaths only in five (17.2%) of the 29 States in 2009 and four (13.8%) in 2015. Sex non-availability for the recorded deaths was much lower as compared with that for age. Interpretation & conclusions: Despite the significant progress made in CoRD in India, critical differences between the States within the CRS remain, with poor availability of reporting by age and sex. Concentrated efforts to assess the strengths and weaknesses at the State level of the CRS processes, quality of data and plausibility of information generated are needed in India.
