Overestimation of Vitamin a Supplementation Coverage from District Tally Sheets Demonstrates Importance of Population-Based Surveys for Program Improvement: Lessons from Tanzania.

Tanzania has conducted a national twice-yearly Vitamin A supplementation (VAS) campaign since 2001. Administrative coverage rates based on tally sheets consistently report >90% coverage; however the accuracy of these rates are uncertain due to potential errors in tally sheets and their aggregation, incomplete or inaccurate reporting from distribution sites, and underestimating the target population. The post event coverage survey in Mainland Tanzania sought to validate tally-sheet based national coverage estimates of VAS and deworming for the June 2010 mass distribution round, and to characterize children missed by the national campaign. WHO/EPI randomized cross-sectional cluster sampling methodology was adapted for this study, using 30 clusters by 40 individuals (n = 1200), in addition to key informant interviews. Households with children 6-59 months of age were included in the study (12-59 months for deworming analysis). Chi-squared tests and logistic regression analysis were used to test differences between children reached and not reached by VAS. Data was collected within six weeks of the June 2010 round. A total of 1203 children, 58 health workers, 30 village leaders and 45 community health workers were sampled. Preschool VAS coverage was 65% (95% CI: 62.7-68.1), approximately 30% lower than tally-sheet coverage estimates. Factors associated with not receiving VAS were urban residence [OR = 3.31; p = 0.01], caretakers who did not hear about the campaign [OR = 48.7; p<0.001], and Muslim households [OR<3.25; p<0.01]. There were no significant differences in VAS coverage by child sex or age, or maternal age or education. Coverage estimation for vitamin A supplementation programs is one of most powerful indicators of program success. National VAS coverage based on a tally-sheet system overestimated VAS coverage by ∼30%. There is a need for representative population-based coverage surveys to complement and validate tally-sheet estimates

Linear programming can help identify practical solutions to improve the nutritional quality of food aid.

OBJECTIVES: To assess the nutritional quality of food aid delivered by food banks in France and to identify practical modifications to improve it. DESIGN: National-level data were collected for all food aid distributed by French food banks in 2004, and its nutrient content per 2000 kcal was estimated and compared with French recommendations for adults. Starting with the actual donation and allowing new foods into the food aid donation, linear programming was used to identify the minimum changes required in the actual donation to achieve the French recommendations. RESULTS: French food-bank-delivered food aid does not achieve the French recommendations for dietary fibre, ascorbic acid, vitamin D, folate, magnesium, docosahexaenoic acid, alpha-linolenic acid and the percentage of energy from saturated fatty acids. Linear programming analysis showed that these recommendations are achievable if more fruits, vegetables, legumes and fish were collected and less cheese, refined cereals and foods rich in fat, sugar and/or salt. In addition, new foods not previously collected are needed, particularly nuts, wholemeal bread and rapeseed oil. These changes increased the total edible weight (42%) and economic value (55%) of the food aid donation, with one-third of its edible weight coming from fruits and vegetables, one-third from staples, one-quarter from dairy products and approximately a tenth from meat/fish/eggs. CONCLUSIONS: Important changes in the types and amounts of food collected will improve the nutritional quality of food-bank-delivered food aid in France. Such changes are recommended to improve the diets of deprived French populations

Predicted efficacy of the Palestinian wheat flour fortification programme: complementary analysis of biochemical and dietary data

Objective: To utilize complementary biochemical and dietary data collected before the initiation of national flour fortification to (i) identify micronutrient insufficiencies or deficiencies and dietary inadequacies in Palestinian women and children in vulnerable communities and (ii) assess the suitability of the current wheat flour fortification formula. Design: Quantitative dietary intake questionnaires were administered and fasting venous blood samples collected in randomly selected households in Gaza City and Hebron. The impact of fortification was simulated by estimating the additional micronutrient content of fortified wheat flour. Setting: Households in Gaza City and Hebron that were not receiving food aid from social programmes. Subjects: Non-pregnant women (18–49 years) and children aged 36–83 months. Results: The micronutrients with highest prevalence of insufficiency were vitamin D in women (84–97 % with serum 25-hydroxyvitamin D \u3c50 nmol/l) and vitamin B12 in women and children (43–82 % with serum B12 \u3c221 pmol/l). Deficiencies of vitamin A, Fe and Zn were also of public health concern. Current levels of wheat flour fortificants were predicted to improve, but not eliminate, micronutrient intake inadequacies. Modification of fortificant concentrations of vitamin D, thiamin, vitamin B12, Zn and folic acid may be indicated. Conclusions: Micronutrient insufficiencies or deficiencies and intake inadequacies were prevalent based on either biochemical or dietary intake criteria. Adjustments to the current fortification formula for wheat flour are necessary to better meet the nutrient needs of Palestinian women and children

Un colis de référence pour une aide alimentaire équilibrée

National audiencePractical and specific guidelines are needed to design nutritionally adequate food baskets for food aid. Since the weight of foods is the only information on food easily available and understandable by non nutritionist field-workers, weight-based guidelines were presently developed. They are compatible with the French foodbased dietary guidelines and take into account that food-insecure individuals have limited access to some foods, such as meat, fish, fruit and vegetables, while refined cereals are the main component of their diets. These guidelines can also be used to evaluate the dietary quality of existing food aid. factual food baskets delivered by food aid agencies in France were compared to the recommended food basket. The results show that fruit and vegetables are severely lacking (only 10% of total food basket weight instead of 33% recommended) while staples, mainly refined cereals, are given in excess (40% instead of 15%), as well as sugar- or saltcontaining food products (9% instead of 2%). This results show that it is necessary to improve the dietary quality of food aid in France and suggest that simple weight-based recommendations can be helpfulL’objectif de cette étude était d’élaborer un colis alimentaire qui puisse servir de référence pour concevoir des colis alimentaires équilibrés et pour évaluer l’équilibre alimentaire de dons existants. Le poids étant la seule information sur les aliments facilement accessible aux bénévoles et salariés travaillant dans les structures d’aide alimentaire, les pourcentages pondéraux des groupes et sous-groupes d’aliments dans le colis de référence forment la base des critères de constitution d’un colis adéquat. Le colis de référence est en accord avec les repères de consommation du PNNS tout en étant spécifique à l’aide alimentaire, car il donne la priorité aux aliments de bonne qualité nutritionnelle que les populations en situation de précarité ont du mal à se procurer. Par rapport au colis de référence, les paniers et colis délivrés par les structures d’aide alimentaire en France, manquent sévèrement de fruits et légumes (10 % du poids total des colis au lieu des 33 % recommandés) et contiennent trop de produits sucrés ou salés (9 % vs 2 %) et trop de féculents, notamment raffinés (40 % vs 15 %). Cette étude montre qu’il est nécessaire d’améliorer la qualité nutritionnelle des dons alimentaires en France, et suggère que la simple diffusion de recommandations basées sur le poids des aliments pourrait y contribue
