Abstract

Neonatal deaths (occurring within 28 days of birth) account for close to one-half of all deaths among children under age 5 worldwide. In most low- and middle-income countries, data on neonatal deaths come primarily from household surveys. We conducted a validation study of survey data on neonatal mortality in Guinea-Bissau (West Africa). We used records from an urban health and demographic surveillance system (HDSS) that monitors child survival prospectively as our reference data set. We selected a stratified sample of 599 women aged 15–49 among residents of the HDSS and collected the birth histories of 422 participants. We cross-tabulated survey and HDSS data. We used a mathematical model to investigate biases in survey estimates of neonatal mortality. Reporting errors in survey data might lead to estimates of the neonatal mortality rate that are too high, which may limit our ability to track progress toward global health objectives.

Two interviews required a translator and were conducted in French (among Fulani migrants recently arrived from the neighboring Republic of Guinea).

In its eighth wave of data collection, the DHS program will begin collecting full pregnancy histories instead of full birth histories in the LMICs where it is implemented (https://​www.​dhsprogram.​com/​pubs/​pdf/​DHSM11/​DHSM11.​pdf).

For example, our study yielded an estimate of the sensitivity of FBH data in recording neonatal deaths that was comparable to the estimate obtained in Bangladesh by Espeut and Becker (2015): .79 versus .82, respectively. However, our study yielded an estimate of the sensitivity of FBH in recording postneonatal deaths that was much lower than the estimate obtained in Bangladesh: .69 versus .87, respectively.
