Conditional cash transfer and/or lipid-based nutrient supplement targeting the first 1000 d of life increased attendance at preventive care services but did not improve linear growth in young children in rural Mali: results of a cluster-randomized controlled trial.

BACKGROUND: In 2014, the World Food Programme added to an ongoing health and nutrition program named "Santé Nutritionnelle à Assise Communautaire dans la région de Kayes" (SNACK), the distribution of cash to mothers and/or lipid-based nutrient supplement (LNS) to children aged 6-23 mo, conditional upon attendance at community health centers (CHCs) during the first 1000 d of life. OBJECTIVE: We evaluated the additional impact of the distribution of cash and/or LNS on mean height-for-age z scores (HAZ; primary outcome), stunting (HAZ < -2), and on intermediate outcomes along the program impact pathways. METHODS: In a cluster-randomized controlled trial using a 2 × 2 factorial design, 76 CHCs were randomly assigned to deliver either SNACK, SNACK + Cash, SNACK + LNS, or SNACK + Cash + LNS. Cross-sectional surveys among 12- to 42-mo-old children and their mothers were conducted at baseline (2013, n = 5046) and at endline (2016, n = 5098). RESULTS: Factorial analysis showed no interaction between cash and LNS treatments for HAZ, but found an antagonistic interaction for stunting (OR: 1.55; 95% CI: 1.05, 2.31; P = 0.03). There were no impacts of the cash, LNS, or cash + LNS treatments, compared with the SNACK alone, on either HAZ or stunting (treatment × time interaction). There were significant impacts of the LNS and cash + LNS treatments on attendance at ≥1 growth monitoring (GM) session (OR: 3.95; 95% CI: 1.69, 9.24; OR: 3.90; 95% CI: 1.73, 8.81, respectively) and half the expected sessions (OR: 4.72; 95% CI: 1.47, 15.17; OR: 5.25; 95% CI: 1.82, 15.11, respectively), mothers' knowledge on importance of GM (OR: 1.98; 95% CI: 1.16, 3.39; OR: 3.12; 95% CI: 1.60, 6.09, respectively), and, only for the LNS group, appropriate timing for complementary feeding (OR: 1.62; 95% CI: 1.09, 2.41). CONCLUSIONS: Implementation constraints and suboptimal participation in program activities may explain the lack of impact on child linear growth in this rural region of Mali.This trial was registered at www.isrctn.com as ISRCTN08435964.

Dissimilarities across age groups in the associations between complementary feeding practices and child growth: Evidence from rural Togo.

Adequate complementary feeding (CF) practices are essential for achieving optimal growth but challenging to measure comprehensively. This paper describes CF practices in 2,034 children aged 6-23 months and investigates their relationships with length-for-age z-score (LAZ) and stunting, using cross-sectional data collected from May to July 2014 in rural Northern Togo. The World Health Organization infant and young child feeding indicators were computed, along with ancillary indicators on feeding style and timing of introduction of complementary foods. The associations between those indicators and children's LAZ and stunting were assessed using linear and logistic regressions after stratification by age group and adjustment for children, maternal, and household characteristics. CF practices were suboptimal, and their associations with child's growth varied across indicators and age groups. In children aged 6-11 months, reaching the minimum dietary diversity and the minimum acceptable diet was associated with higher LAZ (p < .05). In 18- to 23-month-old children, only the consumption of iron-rich food was associated with both LAZ (p = .02) and stunting (p = .05). The late introduction of family foods was associated with higher odds of being stunted and lower LAZ in children aged 12-17 months (p < .001). The untimely introduction of porridge was associated with higher odds of stunting in children aged 9-23 months (p < .05). Unexpectedly, helping the child to eat was negatively associated with linear growth in all age groups. These findings nurture the ongoing process of review of the World Health Organization infant and young child feeding indicators showing that, in their current version, they hardly capture the links between CF and child's growth at different ages.

Vegetable oil of poor quality is limiting the success of fortification with vitamin A in Egypt.

BACKGROUND: Fortification of vegetable oil with vitamin A is considered a cost-effective and simple to implement strategy, but the stability of vitamin A remains a limiting factor. To account for losses of vitamin A, oil producers add an overage. Optimizing the amount of this overage can result in considerable savings for industry and government while ensuring a supply of adequately fortified oil to consumers. OBJECTIVES: To estimate vitamin A losses in oil with different chemical characteristics. METHODS: Samples of fortified oils with different chemical characteristics were collected from two Egyptian companies (oil A and B) and stored for 1 month. Vitamin A levels were analyzed periodically during storage to determine losses over time, and peroxide values were determined. RESULTS: Fortified oil B, with a high peroxide value (5.8 mEq/kg), exposed to sunlight had significantly higher losses of vitamin A after 4 weeks than fortified oil A, with a low peroxide value (0.4 mEq/kg): 31.1% vs. 19.7% (p < .001), respectively. In semidark conditions, the vitamin A losses after 4 weeks in fortified oil B and fortified oil A were significantly different: 26.1% and 0.7% (p < .001), respectively. In an accelerated storage test, the vitamin A loss in 8 days was 48.3% for fortified oil B and 4.2% for fortified oil A (p < .001). CONCLUSIONS: This study shows a significant effect of peroxide level (one indicator of the quality of oil) on the stability of vitamin A, regardless of storage conditions. To optimize and sustain vitamin A levels in fortified oil, governments and industries should minimize the peroxide level to less than 2 mEq/kg at production.

Micronutrient deficits are still public health issues among women and young children in Vietnam.

BACKGROUND: The 2000 Vietnamese National Nutrition Survey showed that the population's dietary intake had improved since 1987. However, inequalities were found in food consumption between socioeconomic groups. As no national data exist on the prevalence of micronutrient deficiencies, a survey was conducted in 2010 to assess the micronutrient status of randomly selected 1526 women of reproductive age and 586 children aged 6-75 mo. PRINCIPAL FINDINGS: In women, according to international thresholds, prevalence of zinc deficiency (ZnD, 67.2 ± 2.6%) and vitamin B12 deficiency (11.7 ± 1.7%) represented public health problems, whereas prevalence of anemia (11.6 ± 1.0%) and iron deficiency (ID, 13.7 ± 1.1%) were considered low, and folate (<3%) and vitamin A (VAD, <2%) deficiencies were considered negligible. However, many women had marginal folate (25.1%) and vitamin A status (13.6%). Moreover, overweight (BMI ≥ 23 kg/m(2) for Asian population) or underweight occurred in 20% of women respectively highlighting the double burden of malnutrition. In children, a similar pattern was observed for ZnD (51.9 ± 3.5%), anemia (9.1 ± 1.4%) and ID (12.9 ± 1.5%) whereas prevalence of marginal vitamin A status was also high (47.3 ± 2.2%). There was a significant effect of age on anemia and ID prevalence, with the youngest age group (6-17 mo) having the highest risk for anemia, ID, ZnD and marginal vitamin A status as compared to other groups. Moreover, the poorest groups of population had a higher risk for zinc, anemia and ID. CONCLUSION: The prevalence of anemia and ID in Vietnam has been markedly reduced over the last decade, but a large part of the population is still at risk for other deficiencies such as zinc, vitamin A, folate and vitamin B(12) especially the youngest children aged 6-17 mo. Consequently specific interventions to improve food diversity and quality should be implemented, among them food fortification of staple foods and condiments and improvement of complementary feeding.
