In recent years there has been significant global momentum on progressing women’s and adolescent girls’ nutrition, led by governments, United Nations agencies, non-governmental organisations (NGOs), research institutions, the private sector and donors. Daily multiple micronutrient supplements (MMS), received through antenatal care (ANC) platforms, have received particular attention. The growing evidence base describing the effectiveness of MMS for birth and maternal outcomes, together with an increasing volume of documented learning about operational aspects from several implementation research pilots, and a strongly supportive advocacy agenda, means that our understanding of the potential impacts of MMS when taken to scale is rapidly improving. However, despite the joint United Nations statement published in 2007, which provided recommendations on the use of MMS in emergencies, there is limited consolidated information on the extent to which women and adolescent girls receive MMS in humanitarian emergencies. Where MMS programming exists in these contexts, details on implementation and barriers to successful scale-up are often lacking. This report aims to fill some of these important knowledge gaps, while recognising that this is simply a starting point for ongoing knowledge sharing and informed action.
