Dietary Sources of Iron in Uganda

Transcription

1 Dietary Sources of Iron in Uganda Data from the 2009/2010 Uganda National Panel Survey Jack Fiedler, Leanne Dougherty, Celeste Sununtnasuk

2 Uganda National Panel Survey 2009/10 UNPS A national survey representative at the regional level Modules: Household, Agriculture, Community Sample size: 2,898 households The 2010/11 survey of the same households has just been released. Another survey is currently being done

3 Uganda National Panel Survey 2009/10 UNPS Household food consumption 61 food items Source: purchases, own productions, gifts Household crop production 57 crops, including 49 food crops Livestock and small animal ownership, fishing

4 What information does the UNPS contain that could be useful in fighting anemia? The consumption module can be used to estimate: 1. Dietary diversity 2. Identify the sources of iron-rich foods being consumed 3. Iron intake levels a. The prevalence of inadequate iron intake (usual daily intake and EAR) b. The magnitude of the iron intake gap

5 UNPS Consumption Module 4. Coverage of food fortification vehicles 5. Commercial fortification impact simulations

6 UNPS Agricultural Module 1. The sources of iron-rich foods being produced 2. What happens to the food that is produced (eaten, sold, stored, etc.) 3. Animal ownership and raising: potential food sources of high bioavailable (heme) iron

7 61 Items UNPS: Consumption Module

8 Dietary Diversity and Nutrition Household Food and Diet Diversity Number of unique food groups consumed over a given reference period Highly predictive of micronutrient intake adequacy of women Highly correlated with hemoglobin concentrations in women and children U5 (and children s anthropometric measures, caloric and protein adequacy and birth weight)

9 Common Food Groups Cereals Roots and Tubers Legumes Eggs Meat and Poultry Fish Fruits Vegetables Nuts Milk Fat and Oils Sugar and Sweets

13 Estimating iron consumption Combining the UNPS food list data with food composition tables allows estimating the apparent household intake of iron With an assumption about how the food is distributed within the household distribution, these estimates can provide a proxy measure of individual iron intakes

18 UNPS agricultural module Food crops Animal ownership Livestock, poultry, fish Animal products Biofortified crops? (Could model adoption and production of orange flesh sweet potato-with minor modifications)

25 Nutrition Programs are Generally Managed as Stand-alone, Independent Interventions Biofortified Food Programs Food Fortification Programs Point-of-Use Fortification (MNP) Programs Insecticide Treated Bednets Deworming Nutrition Status Iron Supplementation Programs 26

26 An Integrated Nutrition Policy Requires an Understanding of the Programs Interactions and Their Harmonization as a Portfolio Biofortified Food Programs Food Fortification Programs Point-of-Use Fortification (MNP) Programs Insecticide Treated Bednets Deworming Nutrition Status Iron Supplementation Programs 27

27 UNPS and Anemia Strategies Anemia rates in Uganda: 49% of children under 5 years 23% of women years The UNPS can help identify: Prevalence of inadequate iron intake across regions and populations Consumption patterns of iron-rich foods Production patterns of iron-rich foods Potential iron fortification vehicles

28 Going Forward Could UBOS, MAAIF and MOH regularly produce a UNPS report on agriculture and food security issues? Could a working group of UBOS, MAAIF, MOH, Makerere strengthen the UNPS as a tool for addressing food and nutrition issues?
