RESUMO

There are limited data on the prevalence of anaemia and iron deficiency (ID) in Somalia. To address this data gap, Somalia's 2019 micronutrient survey assessed the prevalence of anaemia and ID in children (6-59 months) and non-pregnant women of reproductive age (15-49 years). The survey also collected data on vitamin A deficiency, inflammation, malaria and other potential risk factors for anaemia and ID. Multivariable Poisson regressions models were used to identify the risk factors for anaemia and ID in children and women. Among children, the prevalence of anaemia and ID were 43.4% and 47.2%, respectively. Approximately 36% and 6% of anaemia were attributable to iron and vitamin A deficiencies, respectively, whereas household possession of soap was associated with approximately 11% fewer cases of anaemia. ID in children was associated with vitamin A deficiency and stunting, whereas inflammation was associated with iron sufficiency. Among women, 40.3% were anaemic, and 49.7% were iron deficient. In women, ID and number of births were significantly associated with anaemia in multivariate models, and approximately 42% of anaemia in women was attributable to ID. Increased parity was associated with ID, and incubation and early convalescent inflammation was associated with ID, whereas late convalescent inflammation was associated with iron sufficiency. ID is the main risk factor of anaemia in both women and children and contributed to a substantial portion of the anaemia cases. To tackle both anaemia and ID in Somalia, food assistance and micronutrient-specific programmes (e.g. micronutrient powders and iron supplements) should be enhanced.

RESUMO

Food fortification can be effective in reducing the prevalence of anemia and micronutrient deficiencies. This study assessed risk factors for-and the impact of the wheat flour program in Uzbekistan on-anemia, and iron and folate deficiency (FD) in non-pregnant women (NPW) of reproductive age. National data were analyzed for risk factors using multivariable regression. Additional iron intake from fortified flour was not associated with iron deficiency (ID) and did not result in a significantly different prevalence of anemia regardless of the levels, whereas women with additional folic acid intake had a lower relative risk (RR) of FD (RR: 0.67 [95% CI: 0.53, 0.85]). RR for anemia was greater in women with ID (RR: 4.7; 95% CI: 3.5, 6.5) and vitamin A insufficiency (VAI; RR 1.5; 95% CI: 1.3, 1.9). VAI (RR: 1.4 [95% CI: 1.3, 1.6]) and breastfeeding (RR: 1.1 [95% CI: 0.99, 1.2]) were associated with increased risk of ID, while being underweight reduced the risk (RR: 0.74 [95% CI: 0.58, 0.96]). Breastfeeding (RR: 1.2 [95% CI: 1.1, 1.4]) and inflammation (RR: 1.2 [95% CI: 1.0, 1.3]) increased risk of FD. FD results indicate that the fortification program had potential for impact, but requires higher coverage of adequately fortified wheat flour and a more bioavailable iron fortificant.

RESUMO

Background: Globally, iodine deficiency has been drastically reduced since the introduction of salt iodization programs; nonetheless, many populations remain at-risk for iodine deficiency. This study aimed to assess the iodine status among women of reproductive age in Uzbekistan and to identify factors associated with iodine deficiency, including the availability of adequately iodized salt at the household level. Methods: A cross-sectional household survey was conducted to produce region-specific estimates of the household coverage with adequately iodized salt and iodine status among women for each of the 14 regions in Uzbekistan. Other information, such as socioeconomic status, lactation and pregnancy, residence, age, and consumption of iodine supplements, was also collected. Results: Overall, 36% of 3413 households had adequately iodized salt (iodine concentration >15 ppm [parts per million (mg I/kg salt)]), 20% had inadequately iodized salt (5-14 ppm), and 44% had salt without detectable iodine (<5 ppm). Adequate iodization was found in 33.2% of the 2626 salt samples taken from retail packages labeled as "iodized," 36.5% of the 96 samples taken from retail packages without mention of iodization, and 50.5% of the 674 samples without the original packaging (p < 0.001). The median urinary iodine concentration (UIC) of 140.9 µg/L (95% confidence interval [CI 132.4-150.7]) in nonpregnant nonlactating women indicated adequate iodine status, while for nonpregnant lactating and pregnant women, the median UIC of 112.9 µg/L [CI 99.3-128.4] and 117.3 µg/L [CI 101.8-139.9], respectively, indicated borderline adequacy. Significant differences in UIC (p < 0.001) were found between nonpregnant nonlactating women living in households with adequately iodized salt (UIC 208.9 µg/L), inadequately iodized salt (UIC 139.1 µg/L), and noniodized salt (UIC 89.9 µg/L). Conclusions: Coverage with adequately iodized salt is low in Uzbekistan, and women in households with poorly iodized salt have substantially worse iodine status; claims on packaging about salt iodization do not reflect salt iodine content. This highlights the importance and effectiveness of salt iodization and the need to strengthen this program in Uzbekistan.

RESUMO

The Integrated Child Development Services (ICDS) in the State of Telangana, India, freely provides a fortified complementary food product, Bal Amrutham, as a take-home ration to children 6-35 months of age. In order to understand the potential for impact of any intervention, it is essential to assess coverage and utilization of the program and to address the barriers to its coverage and utilization. A two-stage, stratified cross-sectional cluster survey was conducted to estimate the coverage and utilization of Bal Amrutham and to identify their barriers and drivers. In randomly selected catchment areas of ICDS centers, children under 36 months of age were randomly selected. A questionnaire, constructed from different validated and standard modules and designed to collect coverage data on nutrition programs, was administered to caregivers. A total of 1,077 children were enrolled in the survey. The coverage of the fortified take-home ration was found to be high among the target population. Nearly all caregivers (93.7%) had heard of Bal Amrutham and 86.8% had already received the product for the target child. Among the children surveyed, 57.2% consumed the product regularly. The ICDS program's services were not found to be a barrier to product coverage. In fact, the ICDS program was found to be widely available, accessible, accepted, and utilized by the population in both urban and rural catchment areas, as well as among poor and non-poor households. However, two barriers to optimal coverage were found: the irregular supply of the product to the beneficiaries and the intra-household sharing of the product. Although sharing was common, the product was estimated to provide the target children with significant proportions of the daily requirements of macro- and micronutrients. Bal Amrutham is widely available, accepted, and consumed among the target population in the catchment areas of ICDS centers. The coverage of the product could be further increased by improving the supply chain.

RESUMO

Food fortification is a cost-effective approach to prevent and control of micronutrient deficiencies in India. A cross-sectional survey of children 0-35 months of age residing in the catchment areas of anganwadi centers in the state of Telangana was conducted to assess the coverage of adequately iodized salt and the potential for rice fortification. Salt samples were collected and tested for iodine concentration using iodometric titration. Information on demographics, household rice consumption, and Telangana's rice sector was collected and interpreted. In households of selected children, 79% of salt samples were found to be adequately iodized. Salt brand and district were significant predictors of inadequately iodized salt. Daily rice consumption among children and women averaged 122 grams and 321 grams per day, respectively. Approximately 28% of households reported consuming rice produced themselves or purchased from a local farmer, 65% purchased rice from a market or shop, 6% got rice from a public distribution system site, and 2% obtained it from a rice mill. In the catchment areas of Telangana's anganwadi centers, there is significant variation in the coverage of adequately iodized salt by district. Future surveys in Telangana should measure the coverage of salt iodization in the general population using quantitative methods. Nonetheless, increasing the adequacy of iodization of smaller salt manufacturers would help achieve universal salt iodization in Telangana. Despite high consumption of rice, our findings suggest that large-scale market-based rice fortification is not feasible in Telangana due to a large proportion of households producing their own rice and highly fragmented rice distribution. Distributing fortified rice via Telangana's public distribution system may be a viable approach to target low-income households, but would only reach a small proportion of the population in Telangana.

RESUMO

BACKGROUND: The prevalence of stunting, underweight, and micronutrient deficiencies are persistently high in young children in the Philippines, and among other factors, suboptimal infant and young child feeding behavior may contribute to these forms of malnutrition. OBJECTIVE: To improve the understanding of contributors associated with the nutritional status of children 6 to 23 months of age living in urban areas of the Philippines. METHODS: A cross-sectional survey was conducted covering five urban centers in the Philippines. Data on infant and young child feeding and nutritional status (including wasting, stunting, underweight, anemia, iron deficiency, and vitamin A deficiency) were collected for 1,784 children. RESULTS: Among children from urban and predominantly poor and very poor households, 26% were stunted, 18% were underweight, and 5% were wasted. Forty-two percent were anemic, 28% were iron deficient, and 3% were vitamin A deficient. About half of the children were breastfed within an hour after birth, were breastfed at the time of the survey, and had been continuously breastfed up to 1 year of age. Of the factors investigated, low socioeconomic status, use of cheaper cooking fuel, and nonuse of multivitamins were all independently associated with stunting. The prevalence of anemia, iron deficiency, and vitamin A deficiency were independently associated with the same factors and poorer sanitation facilities, lower maternal education, current unemployment, and inflammation. CONCLUSIONS: These factors merit attention in future programming and interventions may include promotion of the timely introduction of appropriate fortified complementary foods, the use of affordable multiple micronutrient preparations, and measures to reduce infections.

RESUMO

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.
