Derivation and appraisal of maternal mortality estimates in Nigeria from the 2012 National HIV/AIDS and Reproductive Health Survey

Resumé

Background: Despite the huge burden of in Nigeria, accurate and reliable data for maternal mortality measurement are lacking. The Federal Ministry of Health in collaboration with development partners included questions that allow indirect estimation of maternal mortality in its 2012 National HIV/AIDS and Reproductive Health Survey (NARHS). The aim of this paper was to derive estimates of Maternal Mortality Ratio (MMR) and Lifetime Risk of maternal death (LTR) from the 2012 NARHS data.

Methods: This was a secondary analysis of data from the maternal mortality module of NARHS 2012. During the survey, respondents (men aged 15-59 years and women aged 15-49 years) were selected via a multi-stage cluster sampling technique and data collected by trained field workers. In this study, report on survival or otherwise of adult female siblings were analysed to derive estimates of life time risk of maternal death using the indirect sisterhood method.

Results: Data from 15, 596 men and 15, 639 women were analysed. A total of 12,810 adult female siblings had been exposed to the risk of death out of which 377 (2.9%) have died. Of the 377 adult female deaths, 70 (18.6%) were pregnancy-related. The estimates of LTR and MMR were 1 in 71 women and 256 (95% CI: 196 – 316) maternal deaths per 100,000 livebirths respectively. There were north-south and rural-urban differences.

Conclusion: The high level of maternal mortality is worrisome, concerted efforts aimed at reduction and provision of routine data for its measurement should be intensified.

Résumé
Contexte: Malgré l’énorme fardeau au Nigeria, des données précises et fiables pour la mesure de la mortalité maternelle sont insuffisantes. Le ministère fédéral de la Santé, en collaboration avec les partenaires du développement, a inclus des questions qui permettent une estimation indirecte de la mortalité maternelle dans son Sondage Nationale sur le VIH / Sida et la Santé Reproductive (NARHS) de 2012. L’objectif de cet article était de tirer des estimations du Ratio de Mortalité Maternelle (RMM) et du Risque à Vie de mortalité maternelle (RV) à partir des données de NARHS 2012. Méthodes: Il s’agissait d’une analyse secondaire des données du module de mortalité maternelle de NARHS 2012. Au cours du sondage, les répondants (hommes âgés de 15 à 59 ans et femmes âgés de 15 à 49 ans) ont été sélectionnés par une technique d’échantillonnage en groupe à plusieurs étapes et les données recueillis par des agents de terrain qualifiés. Dans cette étude, le rapport sur la survie ou autrement des sœurs adultes a été analysé afin de déterminer les estimations du risque à vie de mort maternelle en utilisant la méthode de la fraternité féminine indirecte.

Résultats: Les données provenant de 15.596 hommes et 15.639 femmes ont été analysées. Un total de 12.810 sœurs adultes avait été exposé au risque de décès, dont 377 (2,9%) sont décédés. Des 377 décès de femmes adultes, 70 (18,6%) étaient liés à la grossesse. Les estimations de RV et RMM étaient de 1 femme sur 71 et 256 (95% IC: 196 - 316) de décès maternels pour 100.000 naissances vivantes respectivement. Il y avait des différences nord-sud et rurales-urbaines.

Conclusion: Le taux élevé de mortalité maternelle est inquiétant, des efforts concertés visant à réduire et à fournir des données de routine pour sa mesure devraient être intensifiés.
