OBJECTIVES: In November 2008, the American Academy of Pediatrics (AAP) doubled the recommended daily intake of vitamin D for infants and children, from 200 IU/day (2003 recommendation) to 400 IU/day. We aimed to assess the prevalence of infants meeting the AAP recommended intake of vitamin D during their first year of life. METHODS: Using data from the Infant Feeding Practices Study II, conducted from 2005 to 2007, we estimated the percentage of infants who met vitamin D recommendations at ages 1, 2, 3, 4, 5, 6, 7.5, 9, and 10.5 months (n = 1952–1633). RESULTS: The use of oral vitamin D supplements was low, regardless of whether infants were consuming breast milk or formula, ranging from 1% to 13%, varying by age. Among infants who consumed breast milk but no formula, only 5% to 13% met either recommendation. Among mixed-fed infants, 28% to 35% met the 2003 recommendation, but only 9% to 14% would have met the 2008 recommendation. Among those who consumed formula but no breast milk, 81% to 98% met the 2003 recommendation, but only 20% to 37% would have met the 2008 recommendation. CONCLUSIONS: Our findings suggest that most US infants are not consuming adequate amounts of vitamin D according to the 2008 AAP recommendation. Pediatricians and health care providers should encourage parents of infants who are either breastfed or consuming <1 L/day of infant formula to give their infants an oral vitamin D supplement.

BACKGROUND Although the efficacy of micronutrient powders [MNPs; eg, Sprinkles MNP (Sprinkles Global Health Initiative)] in the reduction of anemia has been established, the effectiveness of these powders in real-world programs has seldom been assessed. OBJECTIVE In this study, we evaluated the effect of community-based marketing and distribution of Sprinkles MNP on childhood rates of anemia and iron and vitamin A deficiency. DESIGN In a cluster-randomized trial in children aged 6-35 mo in Western Kenya, 60 villages were randomly assigned to either intervention or control groups. Community vendors marketed and sold sachets of Sprinkles MNP in intervention villages. Biweekly household visits monitored the use of Sprinkles MNP. Hemoglobin, ferritin, retinol binding protein, malaria, and anthropometric measures were assessed at baseline (n = 1063) and 12 mo of follow-up (n = 862). Data were analyzed by using an intention-to-treat analysis and generalized linear mixed models. RESULTS On average, 33% of households in intervention villages purchased Sprinkles MNP; the average weekly intake per child was 0.9 sachets (∼11.3 mg Fe and ∼328 μg vitamin A). Compared with control subjects, intervention children had greater improvements in hemoglobin concentrations (increase of 0.9 compared with 0.6 g/dL, respectively; P = 0.02), iron deficiency (decrease of 19.3% compared with 5.3%, respectively; P = 0.001), and vitamin A deficiency (decrease of 7.5% compared with an increase of 2.5%, respectively; P = 0.01). Results adjusted for age, sex, socioeconomic status, and maternal education showed a significant association between the hemoglobin, iron, and vitamin A concentrations of children and the number of Sprinkles MNP sachets the children consumed. The prevalence of malaria, wasting, and stunting did not change significantly in either group. CONCLUSION Even with relatively low and infrequent use, Sprinkles MNP sales through community vendors were associated with decreased rates of anemia and iron and vitamin A deficiency in children in a resource-poor setting. This trial was registered at clinicaltrials.gov as NCT01088958.

Background In 2007, the US Centers for Disease Control and Prevention partnered with local Kenyan institutions to implement the Nyando Integrated Child Health and Education Project, an effectiveness study that used social marketing and a community-based distribution program to promote the sale of Sprinkles and other health products. Objective To describe monitoring of wholesale sales, household demand, promotional strategies, and perceived factors influencing Sprinkles sales among vendors. Methods Ongoing quantitative and qualitative monitoring of Sprinkles sales began in May 2007 in 30 intervention villages. Data sources included baseline and follow-up cross-sectional surveys; office records of Sprinkles sales to vendors; biweekly household monitoring of Sprinkles use; and qualitative data collection, including vendor focus groups and key informant interviews. Results A total of 550 children aged 6 to 35 months were enrolled at baseline, and 451 were available at 12-month follow-up. During this period, nearly 160,000 sachets were sold wholesale to vendors, with variability in sales influenced by the social, political, and economic context. Vendors living closer to the wholesale office purchased more Sprinkles, so a second office was opened closer to remote vendors. On average, 33% of house-holds purchased Sprinkles during household monitoring visits. Training sessions and community launches were important for community support and raising awareness about Sprinkles. Vendor incentives motivated vendors to sell Sprinkles, and consumer incentives promoted purchases. Conclusions Sprinkles program monitoring in Kenya was critically important for understanding sales and distribution trends and vendor perceptions. Understanding these trends led to strategic changes to the intervention over time.

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 peoples 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 childrens 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 childs 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

0.08 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.

The use of indoor, three-stone fire pits in resource–poor countries is a substantial burden on human health and the environment. We conducted a pilot intervention promoting the purchase and use of an improved cookstove in rural Kenya. The goals of this qualitative inquiry were to understand the motivation to purchase and use; perceived benefits and challenges of cookstove use; and the most influential promotion activities for scaling up future cookstove promotion. Purposive sampling was used to recruit 10 cookstove promoters and 30 cookstove purchasers in the Luo community. Qualitative semi-structured interviews were transcribed and a thematic analysis conducted. Women reported the need for less firewood, fuel cost savings, reduced smoke, improved cooking efficiency, reduced eye irritation, lung congestion and coughing as major benefits of the cookstove. Cost appeared to be a barrier to wider adoption. The most persuasive promotion strategies were interpersonal communication through social networks and cooking demonstrations. Despite this cost barrier, many women still considered the improved cookstove to be a great asset within their household. This inquiry provided important guidance for future cookstove implementation projects.

To evaluate the sustainability of market-based community distribution of micronutrient powders (Sprinkles(®), Hexagon Nutrition, Mumbai, India.) among pre-school children in Kenya, we conducted in August 2010 a follow-up survey, 18 months after study-related marketing and household monitoring ended. We surveyed 849 children aged 6-35 months randomly selected from 60 study villages. Nutritional biomarkers were measured by fingerstick; demographic characteristics, Sprinkles purchases and use were assessed through household questionnaires. We compared Sprinkles use, marketing efforts and biomarker levels with the data from surveys conducted in March 2007, March 2008 and March 2009. We used logistic regression to evaluate associations between marketing activities and Sprinkles use in the 2010 survey. At the 2010 follow-up, 21.9% of children used Sprinkles in the previous 7 days, compared with 64.9% in 2008 (P < 0.001). Average intake was 3.2 sachets week(-1) in 2008, 1.6 sachets week(-1) in 2009 and 1.1 sachets week(-1) in 2010 (P < 0.001). Factors associated with recent Sprinkles use in 2010 included young age [6-23 months vs. 24-35 months, adjusted odds ratio (aOR) = 1.5, P = 0.02], lowest 2 quintiles of socio-economic status (aOR = 1.7, P = 0.004), household attendance at trainings or launches (aOR = 2.8, P < 0.001) and ever receiving promotional items including free Sprinkles, calendars, cups and t-shirts (aOR = 1.7, P = 0.04). In 2010, there was increased prevalence of anaemia and malaria (P < 0.001), but not iron deficiency (P = 0.44), compared with that in 2008. Sprinkles use in 2010 was associated with decreased iron deficiency (P = 0.03). Sprinkles coverage reduced after stopping household monitoring and reducing marketing activities. Continued promotion and monitoring of Sprinkles usage may be important components to sustain the programme.

Background Micronutrient powders (MNP) reduce anemia and improve iron status in children aged 6 to 23 months. Little is known about home fortification interventions in low-income and middle-income countries. Objective To describe highlights of the Global Assessment of Home Fortification Interventions 2011, new directions, and needed policy and programmatic guidance. Methods A cross-sectional survey of home fortification interventions was conducted. Staff at UNICEF and regional focal points at Home Fortification Technical Advisory Group partner agencies sent questionnaires to representatives in 152 low-income and middle-income countries. Included interventions met the following criteria: they were for prevention and used MNP, lipid-based nutrient supplements (LNS), or complementary food supplements (CFS); one recommended mode of use was mixing into food; they were implemented or planning to start within 12 months; and research interventions were directly linked to programs. Results This study identified 63 implemented interventions (36 countries) and 28 planned interventions (21 countries), including 34 implemented interventions (22 countries) and 25 planned interventions (20 countries) that used MNP. These interventions were expected to reach 17.2 million people in 2011, including 14.1 million participants in MNP interventions. Among implemented interventions, 16% distributed nationally. Most interventions used integrated approaches targeting young children. Recently, there was increasing expansion of interventions in Africa. The main challenges identified were monitoring and evaluation, adherence, product funding, and procurement. Conclusions Home fortification interventions, especially those that use MNP, are increasing and scaling up rapidly in regions with widespread problems of micronutrient deficiencies and stunting. Home fortification interventions contribute to global initiatives to reduce undernutrition.

OBJECTIVE Poor adherence to recommended intake protocols is common and a top challenge for micronutrient powder (MNP) programmes globally. Identifying modifiable predictors of intake adherence could inform the design and implementation of MNP projects. DESIGN We assessed high MNP intake adherence among children who had received MNP ≥2 months ago and consumed ≥1 sachet (n 771). High MNP intake adherence was defined as maternal report of child intake ≥45 sachets. We used logistic regression to assess demographic, intervention components and perception-of-use factors associated with high MNP intake. SETTING Four districts of Nepal piloting an integrated infant and young child feeding and MNP project. SUBJECTS Children aged 6-23 months were eligible to receive sixty MNP sachets every 6 months with suggested intake of one sachet daily for 60 d. Cross-sectional surveys representative of children aged 6-23 months were conducted. RESULTS Receiving a reminder card was associated with increased odds for high intake (OR=2·18, 95 % CI 1·14, 4·18); exposure to other programme components was not associated with high intake. Mothers perceiving ≥1 positive effects in their child after MNP use was also associated with high intake (OR=6·55, 95 % CI 4·29, 10·01). Perceiving negative affects was not associated; however, the child not liking the food with MNP was associated with lower odds of high intake (OR=0·12, 95 % CI 0·08, 0·20). CONCLUSIONS Behaviour change intervention strategies tailored to address these modifiable predictors could potentially increase MNP intake adherence.
