Formative research for the development of a market-based home fortification programme for young children in Niger.

The objective of this formative research was to assess the acceptability of a micronutrient powder (Sprinkles(®)) and a lipid-based nutrient supplement (Nutributter(®)), and to explore people's willingness to pay for these products in a resource-poor context like Niger. In four sites, 84 focus group discussions among mothers, fathers and grandmothers of children 6-23 months were conducted, as well as 80 key informant interviews of mothers who participated in a home study where their children 6-23 months were given either Sprinkles(®) or Nutributter(®) to use either for a period of 4 weeks, or they were given both products over the 4-week period, i.e. Sprinkles(®) for 2 weeks and Nutributter(®) for an additional 2 weeks. The mothers understood how to use the products and generally used the products correctly. Both products were highly acceptable to adults and most children. In Niamey, where the 4-week home study used both products for 2 weeks each, the mothers tended to prefer Nutributter(®). The mothers who used either product were pleased with the improvements they saw in their children's health, including increased appetite, weight gain and increased energy and activity. A few mothers were concerned with how they would be able to provide for their child's increased appetite. Most participants across all four sites reported that they would be willing and able to afford to buy a single sachet of either Sprinkles(®) at a cost of US$0.03 or Nutributter(®) at a cost of US$0.08 several times a week. This study provides evidence that both of these products were are highly acceptable in different settings in Niger and suggests that delivery of Nutributter(®) or Sprinkles(®) at a low or subsidized cost through a market-based system may be possible in Niger, if an appropriate distribution system can be identified.

Prevalence of trachoma in the Kayes region of Mali eight years after stopping mass drug administration.

BACKGROUND: In 2009, three years after stopping mass treatment with azithromycin, a trachoma impact survey in four health districts in the Kayes region of Mali found a prevalence of trachomatous inflammation-follicular (TF) among children aged 1 to 9 years of >5% and a trachomatous trichiasis (TT) prevalence within the general population (≥1-year-old) of <1%. As a result, the government's national trachoma program expanded trichiasis surgery and related activities required to achieve trachoma elimination. METHODOLOGY/PRINCIPAL FINDINGS: In 2015, to assess progress towards elimination, a follow-up impact survey was conducted in the Kayes, Kéniéba, Nioro and Yélimané health districts. The survey used district level two-stage cluster random sampling methodology with 20 clusters of 30 households in each evaluation unit. Subjects were eligible for examination if they were ≥1 year. TF and TT cases were identified and confirmed by experienced ophthalmologists. In total 14,159 people were enumerated and 11,620 (82%) were examined. TF prevalence (95% confidence interval (CI)) was 0.5% (0.3-1%) in Kayes, 0.8% (0.4-1.7%) in Kéniéba, 0.2% (0-0.9%) in Nioro and 0.3% (0.1-1%) in Yélimané. TT prevalence (95% CI) was 0.04% (0-0.25%) in Kayes, 0.29% (0.11-0.6%) in Kéniéba, 0.04% (0-0.25%) in Nioro and 0.07% (0-0.27%) in Yélimané. CONCLUSIONS/SIGNIFICANCE: Eight years after stopping MDA and intensifying trichiasis surgery outreach campaigns, all four districts reached the TF elimination threshold of <5% and three of four districts reached the TT elimination threshold of <0.1%.
