In Haitian women and preschool children, iron absorption from wheat flour-based meals fortified with sodium iron EDTA is higher than that from meals fortified with ferrous fumarate, and is not affected by Helicobacter pylori infection in children.

Fe fortification of wheat flour was proposed in Haiti to combat Fe deficiency, but Fe bioavailability from fortificants has never been investigated in Haitian women or preschool children, two key target groups. We aimed to investigate the bioavailability of ferrous fumarate (FeFum), NaFeEDTA and their combination from fortified wheat flour. We recruited twenty-two healthy mother-child pairs in Port au Prince, Haiti, for an Fe-absorption study. We administered stable Fe isotopes as FeFum or NaFeEDTA individually in low-extraction wheat flour bread rolls consumed by all participants in a randomised, cross-over design. In a final, identical meal, consumed only by the women, FeFum+NaFeEDTA was administered. We measured Fe absorption by using erythrocyte incorporation of stable isotopes 14 d after consumption of each meal, and determined Fe status, inflammatory markers and Helicobacter pylori infection. Fe absorption (geometric mean was 9·24 (95 % CI 6·35, 13·44) and 9·26 (95 % CI 7·00, 12·31) from FeFum and 13·06 (95 % CI 9·23, 19·10) and 12·99 (95 % CI 9·18, 18·39) from NaFeEDTA in mothers and children, respectively (P<0·05 between compounds). Fe absorption from FeFum+NaFeEDTA was 11·09 (95 % CI 7·45, 17·34) and did not differ from the other two meals. H. pylori infection did not influence Fe absorption in children. In conclusion, in Haitian women and children, Fe absorption from NaFeEDTA was 40 % higher than from FeFum, and the combination FeFum+NaFeEDTA did not significantly increase Fe absorption compared with FeFum alone. In the context of Haiti, where the high costs of NaFeEDTA may not be affordable, the use of FeFum at 60 mg Fe/kg flour may be a preferable, cost-effective fortification strategy.

Using programme theory to assess the feasibility of delivering micronutrient Sprinkles through a food-assisted maternal and child health and nutrition programme in rural Haiti.

This paper uses programme theory to assess, in the context of an effectiveness evaluation, the feasibility and acceptability of distributing micronutrient Sprinkles through a food-assisted maternal and child health and nutrition programme in rural Haiti. We laid out the steps related to programme delivery and household utilization of Sprinkles and used qualitative and quantitative methods to gather data on these steps. Methods included structured observations, checks of beneficiary ration cards, exit interviews, focus group discussions (FGD), individual interviews and survey data from the effectiveness evaluation. Results are as follows: (1) information on use of Sprinkles was provided before mothers first received them, as planned; (2) Sprinkles were re-packaged and distributed as planned and in the appropriate amount; (3) almost all mothers (96%) received two monthly rations of Sprinkles and received timely information on their use; (4) mothers understood instructions about use of Sprinkles and acceptance was high, and no selling of the product was reported or observed; and (5) mothers reported using Sprinkles as instructed, every day (63% in survey; 86% at exit interviews), and for the child only (99%). FGD with staff highlighted the acceptance of the intervention, with a reported 'modest' increase in workload. Within this well-established programme, it proved feasible to distribute Sprinkles and to ensure appropriate use by beneficiary mothers. Existing programme venues were suitable for distributing Sprinkles and educating mothers about their use. Use of programme theory helped to assess feasibility and acceptability of the Sprinkles intervention and provided useful information for programme replication or scale-up.

Assessing supervisory and motivational factors in the context of a program evaluation in rural Haiti.

Staff supervisory and motivational factors were assessed in the context of an ongoing program evaluation in Haiti comparing 2 models of targeting an integrated health and nutrition program. The study objectives were to 1) understand and improve supervisory and motivational factors influencing program implementation and 2) compare these factors between the 2 program models being evaluated. Qualitative methods (focus group discussions and semistructured interviews) were used to understand factors related to supervision and motivation. Quantitative measures of supervisory and motivational factors were designed, and factor analysis was used, to develop summary scales of motivational factors and supervision. T-tests were used to compare mean scores on the scales between the 2 program models. Results from the qualitative research were discussed with program management and staff to help develop solutions to implementation bottlenecks. Staff at all levels of the program seemed motivated and generally well supervised. Constraints to motivation included perceived inadequacy of wages (before changes were made to salaries), heavy workloads, and logistical constraints. We found no salient differences between the 2 program models that could contribute to differential implementation or differences in impact. This lack of salient differences between the program models suggested that supervisory and motivational factors were unlikely to contribute to differences in impact. Assessing supervisory and motivational factors was feasible and desirable in the context of this evaluation and deepened understanding of the program context and constraints to implementation.

Micronutrient Sprinkles reduce anemia among 9- to 24-mo-old children when delivered through an integrated health and nutrition program in rural Haiti.

We evaluated the effectiveness of a 2-mo treatment of Sprinkles containing 12.5 mg iron, 5 mg zinc, 400 microg vitamin A, 160 microg folic acid, and 30 mg vitamin C in reducing anemia among children 9- to 24 mo old in Haiti. Ten food distribution points (FDP) where children received take-home rations of fortified wheat-soy blend (WSB) were randomly allocated into 2 groups: 1) Sprinkles-WSB (S-WSB) (6 FDP; n = 254), receiving 30 sachets of Sprinkles monthly for 2 mo; and 2) WSB only (WSB) (4 FDP; n = 161), not receiving Sprinkles. At baseline, anemia prevalence [hemoglobin (Hb) < 100 g/L], adjusted for age and sex, was 54 and 39% in S-WSB and WSB groups, respectively. After the 2-mo intervention (1st follow-up), anemia, adjusted for baseline prevalence, age, and sex dropped to 24% in S-WSB (P < 0.001) and increased to 43% in WSB (P = 0.07). At 7 mo postintervention, anemia in S-WSB declined to 14%; 92% of children who were nonanemic at 1st follow-up remained so without further Sprinkles consumption. From baseline to 1st follow-up, mean Hb increased by 5.5 g/L and dropped by 1.0 g/L in the S-WSB and WSB groups, respectively (P < 0.001). From baseline to 2nd follow-up, mean Hb increased by 10.9 g/L in S-WSB (P < 0.001). Changes in mean Hb were greater for younger children (<21 mo at onset of intervention) (P < 0.05) and for children who were anemic at baseline (P < 0.001). In populations with a high prevalence of anemia, such as rural Haiti, 2 mo of Sprinkles are effective in reducing anemia among 9- to 24-mo-old children.
