Figure 4 Relative Odds of Death for Children Under Age 5, Based on Nutritional Status Odds ratio for children under five who are malnourished than for those who are not.73 Thus, improving early childhood nutrition can also help meet MDG 6: Combat HIV/AIDS, Malaria, and Other Diseases. People’s ability to fight diseases and infections such as HIV and malaria is also influenced by their nutritional status. Infections and malnutrition exacerbate each other, potentially creating a vicious spiral into ill health and ultimately death.74 Good nutrition, on the other hand, may contribute to slowing the progression of diseases and can optimize the benefits of drugs used to treat the diseases. For those who are living with HIV—especially small children— good nutrition is key to recovery from opportunistic infections.75 10 9 8 7 6 5 4 3 2 1 0 9.4 8.7 6.3 3 2.9 1.6 1.6 1 all deaths death from diarrhea 4.2 3.2 2.1 1 1.3 death from pneumonia 3.7 2.8 3 2.3 1 1 death from malaria 1.7 1 death from measles ■ if properly nourished ■ if stunted (but not severely) ■ if severely stunted ■ if wasted (but not severely) ■ if severely wasted Source: The Lancet (2008). Parasite Control Parasitic infections exacerbate undernutrition, and vice versa. For example, intestinal worms can cause iron-deficiency anemia by feeding directly on the blood of their host.76 Controlling parasites requires measures such as preventing malaria and providing education on preventing hookworms, as well as more direct treatment of parasitic infections. Vaccination campaigns and community outreach health services provide platforms to deliver deworming treatments. Pregnant women should benefit from active parasite prevention—especially malaria prevention—since malaria during pregnancy contributes to infant mortality. Malaria prevention and control programs should prioritize correct diagnosis and treatment of malaria according to national protocols and ensure availability and adherence to anti-malarial medications for all pregnant women. For example, Intermittent Preventive Treatment is a full therapeutic dose of an antimalarial drug given to pregnant women at specified intervals in the second and third trimesters. Insecticide-treated nets should be promoted and distributed for increased access and use, especially by pregnant women and young children. Water, Sanitation, and Hygiene Water, sanitation, and hygiene programs are key to preventing intestinal parasites and other diseases associated with contaminated water or poor hygiene. Malnutrition-associated diarrheal infection can be addressed by integrating such programs with health and nutrition programs. Facilities providing potable water and good sanitation can dramatically improve nutrition. Howevwww.bread.org 4.6 4.1 1 6 er, such improvements are significantly undercut when individual households are unable to store water safely. The Lancet series on maternal and child undernutrition found that sanitation and hygiene interventions that reached a high proportion of the target populations reduced the prevalence of diarrhea and, in turn, stunting. Diarrheal diseases and related malnutrition account for virtually all of the deaths and nearly 90 percent of the overall disease burden associated with unsafe water supplies and inadequate sanitation and hygiene. Agriculture, Health, and Nutrition Linkages Volatile food prices, increased food insecurity, and hunger emergencies—including famines—have led to an increased focus on global agriculture interventions. Developing countries generally face seasonal variations in food availability—“hunger seasons” are common in some areas. Hunger or risk of hunger is linked, of course, to physical and emotional suffering. Food insecurity compromises dietary quality and nutritional status. Hunger and food insecurity disproportionately affect vulnerable populations such as women, children, and people living with HIV/AIDS. The damage to children from food insecurity is particularly worrisome since adequate nutrition is vital to children’s physical and cognitive health and development. USAID defines food security77 as: “When all people at all times have both physical and economic access to sufficient food to meet their dietary needs in order to lead a healthy and productive life.” This definition of food security has three components—food must be available, accessible, and actually consumed. Food security can only be achieved if a Bread for the World Institute 11
