Poverty and a lack of awareness seem to be at the heart of the problem of childhood malnutrition in Nigeria. Until the socioeconomic status of the vast majority of Nigerians improves significantly, malnutrition will continue to pose a serious threat to the growth and development of Nigerian children and the future of national development. Significant variations exist in the level of child and maternal malnutrition across rural/urban settings, geopolitical zones, and agro-ecological bands in Nigeria. Malnutrition rates are higher among rural households who depend more on agriculture than on other sectors for their livelihoods. A range of socioeconomic, demographic, and public health related factors work together to influence maternal and child nutrition outcomes among rural and urban dwellers across the geopolitical zones and agro-ecological zones in Nigeria.

There is a growing interest in the research literature in exploring how child nutrition is affected by sociocultural practices, such as polygyny. However, evaluation of the effect of polygyny on child nutrition has been hindered by the complexity of the relationship. This paper investigates the effect of polygyny on anthropometric outcomes while recognizing that unobservable household characteristics may simultaneously influence both the decision to form a polygynous union and the ability of the household to adequately nourish children. Polygyny can affect children’s nutrition through increased family size, early marriage, and the level of household investment in child health. In this paper, we apply an instrumental variable approach based on the occurrence of same sex siblings in a woman’s first two births to generate exogenous variation in polygyny. Using data from the 2008 and 2013 Nigeria Demographic and Health Surveys, we find a detrimental effect of polygyny on child undernutrition, with a greater effect in poorer households and those resident in more urban locations.

Current data and trends in morbidity and mortality for the sub-Saharan Region as presented in this new edition reflect the heavy toll that HIV/AIDS has had on health indicators, leading to either a stalling or reversal of the gains made, not just for communicable disorders, but for cancers, as well as mental and neurological disorders.

This report examines nutrition, providing a fresh perspective on a rapidly evolving challenge. Despite progress in the past two decades, around 200 million under-fives suffer from undernutrition. Adding to this toll is rising obesity, which affects 38 million children. All these forms of malnutrition threaten children’s development, while obesity is creating a lifelong legacy of disease. At the heart of this evolving challenge is a global shift towards modern diets that do not meet children’s nutritional requirements. The report provides unique data and analysis of malnutrition in the 21st century and outlines recommendations to put children’s needs at the heart of global and national food systems.

Considering the detrimental environmental impact of current food systems, and the concerns raised about their sustainability, there is an urgent need to promote diets that are healthy and have low environmental impacts. These diets also need to be socio-culturally acceptable and economically accessible for all. Acknowledging the existence of diverging views on the concepts of sustainable diets and healthy diets, countries have requested guidance from the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) on what constitutes sustainable healthy diets. These guiding principles take a holistic approach to diets; they consider international nutrition recommendations; the environmental cost of food production and consumption; and the adaptability to local social, cultural and economic contexts. This publication aims to support the efforts of countries as they work to transform food systems to deliver on sustainable healthy diets, contributing to the achievement of the SDGs at country level, especially Goals 1 (No Poverty), 2 (Zero Hunger), 3 (Good Health and Well-Being), 4 (Quality Education), 5 (Gender Equality) and 12 (Responsible Consumption and Production) and 13 (Climate Action).

Although the percentage of children who are malnourishes has declined in many countries of the developing world in recent years, the absolute number of malnourished children is rising in some regions, particulary in Sub-Saharan Africa. This paper aims to determine which of the various causes of mal nutrition are most important for the developing countries as a whole and by region, thus enabling policymakers to prioritize their investments and make the besy use of available resources to reduce malnutrition now and in coming years.

One in three preschool children in developing countries is undernourished. Consequently, they are likely to have impaired immune systems, poor cognitive development, low productivity as adults, and susceptibility to diet-related chronic diseases such as hypertension and coronary heart disease later in life. Undernourished female preschoolers are likely to grow into undernourished young women who are more likely to give birth to babies who are undernourished even before they are born, thus perpetuating the intergenerational transmission of deprivation. This report sheds light on some of the main causes of child malnutrition, projects how many children are likely to be malnourished in the year 2020 given current trends, and identifies priority actions for reducing malnutrition most quickly in the coming decades.
