Ethics approval and consent to participate
: We obtained an umbrella agreement for longitudinal monitoring of vital statistics (pregnancy, birth, death, in-migration and out-migration), health-related research, and public health interventions by the Comité National d’Ethique et de Recherche (CNER) in Côte d’Ivoire (reference no. 1086 MSHD/CNEF) and the Ethikkommission beider Basel (EKBB) in Switzerland (reference no. 316/08). The current project was approved by the institutional research commissions of the Centre Suisse de Recherches Scientifiques en Côte d’Ivoire (CSRS; Abidjan, Côte d’Ivoire) and the Swiss Tropical and Public Health Institute (Swiss TPH; Basel, Switzerland) and local authorities. Participation was voluntary and women identified to be pregnant were informed about the aim of the questionnaire and their rights to withdraw from the study at any time without further obligation. On top of our umbrella agreement from the national ethics committee, women provided oral informed consent and this procedure was approved prior to the start of our study.
