Description
Summary:Objective To estimate the prevalence of alcohol consumption and binge drinking during pregnancy among the general population in the World Health Organization (WHO) African Region, by country. Methods First, a comprehensive systematic literature search was performed to identify all published and unpublished studies. Then, several meta‐analyses, assuming a random‐effects model, were conducted to estimate the prevalence of alcohol consumption and binge drinking during pregnancy among the general population for countries in the WHO African Region with two or more studies available. Lastly, for countries with less than two studies or no known data predictions were obtained using regression modelling. Results The estimated prevalence of alcohol consumption during pregnancy among the general population ranged from 2.2% (95% confidence interval [CI]: 1.6–2.8%; Equatorial Guinea) to 12.6% (95% CI: 9.9–15.4%; Cameroon) in Central Africa, 3.4% (95% CI: 2.6–4.3%; Seychelles) to 20.5% (95% CI: 16.4–24.7%; Uganda) in Eastern Africa, 5.7% (95% CI: 4.4–7.1%; Botswana) to 14.2% (95% CI: 11.1–17.3%; Namibia) in Southern Africa, 6.6% (95% CI: 5.0–8.3%; Mauritania) to 14.8% (95% CI: 11.6–17.9%; Sierra Leone) in Western Africa, and 4.3% (95% CI: 3.2–5.3%; Algeria) in Northern Africa. Conclusions The high prevalence of alcohol consumption and binge drinking during pregnancy in some African countries calls for educational campaigns, screening and targeted interventions for women of childbearing age. Objectif Estimer la prévalence de la consommation d'alcool et de la consommation excessive d'alcool pendant la grossesse dans la population générale dans la Région africaine de l’OMS, par pays. Méthodes D'abord, une recherche exhaustive systématique de la littérature a été réalisée afin d'identifier toutes les études publiées et non publiées. Ensuite, plusieurs méta‐analyses, en supposant un modèle à effets aléatoires, ont été réalisées pour estimer la prévalence de la consommation d'alcool et de la consommation excessive d'alcool pendant la grossesse dans la population générale pour les pays de la Région africaine de l’OMS avec deux ou plusieurs études disponibles. Enfin, pour les pays avec peu ou pas de données connues, les prédictions ont été obtenues en utilisant un modèle de régression. Résultats La prévalence estimée de la consommation d'alcool pendant la grossesse dans la population générale varie de 2,2% (intervalle de confiance [IC] 95%: 1,6% ‐ 2,8%, Guinée équatoriale) à 12
