Nutrition for women in pre-pregnancy, pregnancy, and over the first two years of the child’s life is of utmost importance for the survival, health and development of mothers and their children. In pregnancy, requirements of energy, protein, and essential micronutrients are increased not only to maintain the mother’s own health, but to also support optimal physical and brain development in the foetus and thereafter in the young child. Thus there is a need to integrate nutrition within policy and programmes to improve maternal health, with a cascading impact on the child. This policy brief forms a part of a series developed by RESULTS UK to document best practice in integrating nutrition within policy, programmes and investments for Reproductive, Maternal, Newborn, Child, and Adolescent Health (RMNCAH). This brief focuses on maternal health and nutrition, taking Pakistan as a case study.
