Timor-Leste has the highest rate of child malnutrition in Asia with over half of children under five stunted (low height for age). Research shows that rates of exclusive breastfeeding vary widely across the country (28-75%) and there is a lack of dietary diversity with only 18% of children under two consuming a minimum acceptable diet. HAI was awarded a grant by UNICEF to establish and mentor Mother Support Groups (MSGs) in two municipalities in Timor-Leste. The goal of the MSGs is to promote key home practices focused on nutrition with the aim to improve maternal and child health outcomes. The groups are composed of community volunteers, both men and women, and are implemented in every village in the municipality. HAI works closely with the Ministry of Health and the municipality health team to establish and run the groups. It is intended that MSGs will be mainstreamed into the duties of village-based doctors and will strengthen the link between health providers and the communities they serve.
