Objective: Child mortality and stillbirth rates (SBR) remain high in low‐income countries but may be underestimated due to incomplete reporting of child deaths in retrospective pregnancy/birth histories. The aim of this study is to compare stillbirth and mortality estimates derived using two different methods: the method assuming full information and the prospective method. Methods: Bandim Health Project's Health and Demographic Surveillance Systems (HDSS) follows women of reproductive age and children under five through routine home visits every 1, 2 or 6 months. Between 2012 and 2020, we estimated and compared early neonatal (ENMR, <7 days), neonatal (NMR, <28 days), and infant mortality (IMR, <1 year) per 1000 live births and SBR per 1000 births. Risk time for children born to registered women was calculated from birth (the method assuming full information) versus date of first observation in the HDSS (the prospective method), either at birth (for pregnancy registration) or registration. Rates were calculated using the Kaplan–Meier estimator and compared in generalised linear models allowing for within‐child correlation obtaining relative risks (RR). Results: We registered and followed 29,413 infants (1380 deaths; 1459 stillbirths) prospectively. An additional 164 infant deaths and 129 stillbirths were registered retrospectively and included in the method assuming full information. The ENMR was 24.5 (95%CI: 22.6–26.4) for the method assuming full information and 25.8 (23.7–27.8) for the prospective method, RR = 0.96 (0.93–0.99). Differences were smaller for the NMRs and IMRs. For SBRs, the estimates were 53.5 (50.9–56.0) and 58.6 (55.7–61.5); RR = 0.91 (0.90–0.93). The difference between methods became more pronounced when the analysis was limited to areas visited every 6 months: RR for ENMR: 0.91 (0.86–0.96) and RR for SBR: 0.85 (0.83–0.87). Conclusions: Assuming full information underestimates SBR and ENMR. Accounting for omissions of stillbirths and early neonatal deaths may lead to more accurate estimates and improved ability to monitor mortality. [ABSTRACT FROM AUTHOR] |
