RESUMO

OBJECTIVE: To assess oil consumption, vitamin A intake and retinol status before and a year after the fortification of unbranded palm oil with retinyl palmitate. DESIGN: Pre-post evaluation between two surveys. SETTING: Twenty-four villages in West Java. SUBJECTS: Poor households were randomly sampled. Serum retinol (adjusted for subclinical infection) was analysed in cross-sectional samples of lactating mothers (baseline n 324/endline n 349), their infants aged 6-11 months (n 318/n 335) and children aged 12-59 months (n 469/477), and cohorts of children aged 5-9 years (n 186) and women aged 15-29 years (n 171), alongside food and oil consumption from dietary recall. RESULTS: Fortified oil improved vitamin A intakes, contributing on average 26 %, 40 %, 38 %, 29 % and 35 % of the daily Recommended Nutrient Intake for children aged 12-23 months, 24-59 months, 5-9 years, lactating and non-lactating women, respectively. Serum retinol was 2-19 % higher at endline than baseline (P<0·001 in infants aged 6-11 months, children aged 5-9 years, lactating and non-lactating women; non-significant in children aged 12-23 months; P=0·057 in children aged 24-59 months). Retinol in breast milk averaged 20·5 µg/dl at baseline and 32·5 µg/dl at endline (P<0·01). Deficiency prevalence (serum retinol <20 µg/dl) was 6·5-18 % across groups at baseline, and 0·6-6 % at endline (P≤0·011). In multivariate regressions adjusting for socio-economic differences, vitamin A intake from fortified oil predicted improved retinol status for children aged 6-59 months (P=0·003) and 5-9 years (P=0·03). CONCLUSIONS: Although this evaluation without a comparison group cannot prove causality, retinyl contents in oil, Recommended Nutrient Intake contributions and relationships between vitamin intake and serum retinol provide strong plausibility of oil fortification impacting vitamin A status in Indonesian women and children.

RESUMO

BACKGROUND: Simple-to-use quantitative methods are needed to check the adequacy of vitamin A fortification levels. OBJECTIVE: To assess the capacity of a portable fluorometer (iCheck FLUORO) and its test kit vials (iEx Mila) to quantify retinyl palmitate in fortified milks, flours (wheat, maize), and sugar. METHODS: The portable fluorometer was assessed in a three-step procedure to determine its working range and linearity, intra-assay precision, and interperson precision. Measurements were compared with the results obtained by high-performance liquid chromatography (HPLC), commonly regarded as the standard method for vitamin A analysis. RESULTS: The portable fluorometer (iCheck FLUORO) and its test kit vials (iEx Mila) precisely determined the vitamin A contents in fortifed flours, sugar, and milks. Its working range was 1 to 10, 0.5 to 3.0, and 5 to 15 mg retinol equivalents (RE) kg(-1) for flours (wheat and corn), milks, and sugar, respectively; these values are in accordance with the World Health Organization recommendations for food fortification in least developed countries. The limits of detection are higher than those of HPLC but are all satisfactory (< 1.46 mg RE kg(-1)). The coefficients of variation within and between observers were satisfactory, especially for sugar and milk. CONCLUSIONS: The linear relationship between the data from the portable fluorometer and the HPLC data confirms that the portable fluorometer provides a good determination of the vitamin A content of the fortified products in the tested range.

RESUMO

BACKGROUND: Access to high-grade micronutrients is a recurring challenge that often threatens the long-term sustainability of food fortification programs. OBJECTIVE: To assess the efficiency of the Global Alliance for Improved Nutrition (GAIN) Premix Facility in procuring quality, affordable vitamin A for fortification of edible oil in Indonesia. METHODS: A global approach to procurement of standard items was used by combining volumes across various demand streams in order to reduce the total cost of acquisition through economies of scale. The GAIN Premix Facility undertook a detailed analysis of vitamin A requirements across its existing customer base, which served as a basis for developing a reliable demand forecast. A consolidated, competitive tender was launched that resulted in the setting up of a long-term commercial agreement with the selected supplier to lock in the most competitive price for a given period of time. RESULTS: The direct benefit to oil manufacturers of fortifying with vitamin A is that the cost of fortification went down significantly compared with prices they would have been offered had they ordered vitamin A individually. In Indonesia, this consolidated procurement approach has allowed a 14.5% decrease in the unit price of vitamin A. CONCLUSIONS: The GAIN Premix Facility demonstrated its effectiveness in acting as a global procurement platform by aggregating demand across different customers and leveraging improved prices through increased volumes. Building on the success of this effort, the GAIN Premix Facility is replicating this global approach for procurement of other standard items being procured across fortification programs worldwide.

RESUMO

BACKGROUND: Vitamin A deficiency is a public health problem worldwide, affecting approximately 190 million preschool-aged children and 19.1 million pregnant women. Fortification of vegetable oils with vitamin A is an effective, low-cost technology to improve vitamin A intake. OBJECTIVE: To examine the potential contribution of fortification of vegetable oils with vitamin A in Indonesia and Malaysia to increasing vitamin A consumption in these two countries and in countries to which oil is exported. METHODS: Detailed interviews were administered and a desk review was conducted. We also estimated potential vitamin A intakes from fortified vegetable oil. RESULTS: Malaysia and Indonesia are two of the largest producers and exporters of vegetable oil. Fortification of vegetable oil in both countries has the potential to be used as a tool for control of vitamin A deficiency. Both countries have the capacity to export fortified vegetable oil. Vegetable oil fortified at a level of 45 IU/g could provide 18.8% of the Estimated Average Requirement (EAR) for an Ethiopian woman, 30.9% and 46.9% of the EAR for a Bangladeshi child and woman, respectively, and 17.5% of the EAR for a Cambodian woman. Although concerns about obesity are valid, fortification of existing vegetable oil supplies does not promote overconsumption of oil but rather promotes consumption of vegetable oil of higher nutrient quality. CONCLUSIONS: Fortifying vegetable oil on a large scale in Malaysia and Indonesia can reach millions of people globally, including children less than 5 years old. The levels of fortification used are far from reaching the Tolerable Upper Intake Level (UL). Vegetable oil fortification has the potential to become a global public health intervention strategy.

RESUMO

BACKGROUND: Vitamin D is vital for bone health and has important roles in nonskeletal health and organ function. Most vitamin D is generated in the body by exposure to sunlight, with limited amounts added by the diet. Despite the presence of regular sunshine in Southeast Asia, vitamin D deficiency or insufficiency is being found there more commonly, primarily due to reduction of sunlight exposure as a result of lifestyle changes. Some of these lifestyle changes are unlikely to be reversed, and foods naturally containing vitamin D are not widely consumed, so fortification of foods with vitamin D may raise vitamin D status. METHODS: The literature database was searched for studies of vitamin D fortification, and we estimated potential vitamin D intakes from fortified vegetable oil. RESULTS: Almost all of the studies showed that circulating vitamin D (25-hydroxyvitamin D [(25OHD]) increased in a dose-dependent manner with increased intake of vitamin D-fortified foods. However, in a number of studies the additional intake was insufficient to increase vitamin D levels to 50 nmol/L. Vegetable oil fortified with vitamin D at a level of 10 microg/100 g could provide 3.9% to 21% of the Institute of Medicine Estimated Average Requirement (EAR) of vitamin D for adults in Southeast Asia. CONCLUSIONS: Fortification of widely consumed foods, such as edible oil, with vitamin D could contribute to improved vitamin D status in Southeast Asian countries. Intake modeling studies should be conducted to calculate the resulting additional intakes, and fortification of additional foods should be considered. More nationally representative studies of vitamin D status in the region are urgently needed.

RESUMO

BACKGROUND: The prevalence of micronutrient deficiencies in Cambodia is among the highest in Southeast Asia. Fortification of staple foods and condiments is considered to be one of the most cost-effective strategies for addressing micronutrient deficiencies at the population level. The Government of Cambodia has recognized the importance of food fortification as one strategy for improving the nutrition security of its population. OBJECTIVE: This paper describes efforts under way in Cambodia for the fortification of fish sauce, soy sauce, and vegetable oil. METHODS: Data were compiled from a stability test of Cambodian fish sauces fortified with sodium iron ethylenediaminetetraacetate (NaFeEDTA); analysis of fortified vegetable oils in the Cambodian market; a Knowledge, Attitudes, and Practices (KAP) study of fortified products; and food fortification program monitoring documents. RESULTS: At different levels of fortification of fish sauce with NaFeEDTA, sedimentation and precipitation were observed. This was taken into consideration in the government-issued standards for the fortification of fish sauce. All major brands of vegetable oil found in markets at the village and provincial levels are imported, and most are nonfortified. CONCLUSIONS: Fish sauce, soy sauce, and vegetable oil are widely consumed throughout Cambodia and are readily available in provincial and village markets. Together with an effective regulatory monitoring system, the government can guarantee that these commodities, whether locally produced or imported, are adequately fortified. A communications campaign would be worthwhile, once fortified commodities are available, as the KAP study found that Cambodians had a positive perception of fortified sauces.

RESUMO

BACKGROUND: To further reduce stunting in Southeast Asia, a rapidly changing region, its main causes need to be identified. OBJECTIVE: Assess the relationship between different causes of stunting and stunting prevalence over time in Southeast Asia. METHODS: Review trends in mortality, stunting, economic development, and access to nutritious foods over time and among different subgroups in Southeast Asian countries. RESULTS: Between 1990-2011, mortality among under-five children declined from 69/1,000 to 29/1,000 live births. Although disease reduction, one of two direct causes of stunting, has played an important role which should be maintained, improvement in meeting nutrient requirements, the other direct cause, is necessary to reduce stunting further. This requires dietary diversity, which is affected by rapidly changing factors: economic development; urbanization, giving greater access to larger variety of foods, including processed and fortified foods; parental education; and modernizing food systems, with increased distance between food producers and consumers. Wealthier consumers are increasingly able to access a more nutritious diet, while poorer consumers need support to improve access, and may also still need better hygiene and sanitation. CONCLUSIONS: In order to accelerate stunting reduction in Southeast Asia, availability and access to nutritious foods should be increased by collaboration between private and public sectors, and the Association of Southeast Asian Nations (ASEAN) can play a facilitating role. The private sector can produce and market nutritious foods, while the public sector sets standards, promotes healthy food choices, and ensures access to nutritious foods for the poorest, e.g, through social safety net programs.

RESUMO

INTRODUCTION: A well-nourished workforce is instrumental in eradicating hunger, alleviating poverty, and spurring economic growth. A fifth of the total workforce in high-income countries are migrant workers. Despite the accessibility of nutritious foods in high-income countries, migrant workers often rely on nutrient-poor diets largely consisting of empty calories, which in turn leads to vitamin and mineral deficiency, also called hidden hunger, and resultant productivity loss. Here, we study the magnitude of hidden hunger in male migrant construction workers in Singapore and investigate the impact of consuming fortified rice for 6 consecutive months on the nutrition and health status of these workers. METHODS: 140 male migrant workers aged 20-51 years of either Bangladeshi or Indian ethnicity from a single dormitory in Singapore volunteered to participate in the study. In total, 133 blood samples were taken at the start of the study and were used to assess vitamin B12, hemoglobin, ferritin, folate, and zinc levels; a sub-sample underwent for homocysteine testing. Anthropometric measurements and vital signs, such as blood pressure, were recorded before and after the intervention. RESULTS: The results show that vitamin and mineral deficiency was present, especially folate (59% of workers deficient) and vitamin B12 (7% deficient, 31% marginally deficient). The consumption of fortified rice significantly improved the vitamin, iron and zinc level in the workers and significantly reduced the systolic blood pressure amongst the Bangladeshi migrant workers, specifically. CONCLUSION: Our study demonstrates that fortified rice may have a positive impact on male migrant construction worker health and nutrition status at the workplace.

RESUMO

Our specific aim was to characterize maternal knowledge of anemia and its relationship to maternal and child anemia and to behaviors related to anemia reduction. We examined the relationship between maternal knowledge of anemia and anemia in the mother and the youngest child, aged 6-59 months, in 7,913 families from urban slums and 37,874 families from rural areas of Indonesia. Knowledge of anemia was defined based upon the mother's ability to correctly name at least one symptom of anemia and at least one treatment or strategy for reducing anemia. Hemoglobin was measured in both the mother and the child. In urban and rural areas, respectively, 35.8 and 36.9% of mothers had knowledge of anemia, 28.7 and 25.1% of mothers were anemic (hemoglobin <12 g/dL), and 62.3 and 54.0% of children were anemic (hemoglobin <11 g/dL). Maternal knowledge of anemia was associated with child anemia in urban and rural areas, respectively (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.79, 1.02, P = 0.10; OR 0.93, 95% CI 0.87, 0.98, P = 0.01) in multivariate logistic regression models adjusting for potential confounders. There was no significant association between maternal knowledge of anemia and maternal anemia. Maternal knowledge of anemia was significantly associated with iron supplementation during pregnancy and child consumption of fortified milk. There was no association of maternal knowledge of anemia with child deworming. Maternal knowledge of anemia is associated with lower odds of anemia in children and with some health behaviors related to reducing anemia.

RESUMO

OBJECTIVES: To describe risk factors for clustering of anemia among mothers and children in Indonesia. METHODS: An anemia cluster was defined as hemoglobin <12 g/dl in the mother and <11 g/dl in the youngest child, aged 6-59 months. RESULTS: Anemia clustering occurred in 4907 (18.3%) of 26 809 urban families and 12 756 (15.5%) of 82 291 rural families. Maternal overweight/obesity, older child age, consumption of fortified milk by the child, use of iodized salt, vitamin A supplementation, paternal smoking and greater expenditure on animal and plant source foods were associated with lower odds of anemia clustering. Older maternal age, maternal underweight, ≥2 children in the family and >4 individuals eating from the same kitchen were associated with greater odds of anemia clustering. CONCLUSION: Fortified milk, iodized salt, vitamin A supplementation and greater expenditure on plant and animal foods are among modifiable risk factors associated with lower risk of anemia clustering in Indonesia.

RESUMO

BACKGROUND: Despite improved economic conditions, vitamin A deficiency remains a public health problem in Indonesia. OBJECTIVE: This paper aims to describe the development of the Indonesian unbranded cooking oil fortification program and to discuss lessons learned to date and future steps necessary for implementation of mandatory, large-scale oil fortification with vitamin A. METHODS: An historic overview of the steps involved in developing the Indonesian unbranded cooking oil fortification program is given, followed by a discussion of lessons learned and next steps needed. RESULTS: Indonesia's low-income groups generally consume unbranded vegetable oil, with an average consumption of approximately 25 g/day. Unbranded oil constitutes approximately 70% of the total oil traded in the country. In 2007-10, a pilot project to fortify unbranded vegetable oil was carried out in Makassar, and an effectiveness study found that the project significantly improved the serum retinol concentrations of schoolchildren. In 2010, the pilot was expanded to two provinces (West Java and North Sumatra) involving the biggest two national refineries. In 2011, a draft national standard for fortified oil was developed, which is currently under review by the National Standard Body and is expected to be mandated nationally in 2013 as announced officially by the Government of Indonesia in national and international meetings. CONCLUSIONS: Indonesia is a leading world supplier of cooking oil. With stakeholder support, the groundwork has been laid and efforts are moving forward to implement mandatory fortification. This project could encourage Indonesian industry to fortify more edible oils for export, thus expanding their market potential and potentially reducing vitamin A deficiency in the region.

RESUMO

The Global Alliance for Improved Nutrition (GAIN) was established in 2002 with a mandate to galvanize efforts by the public and private sectors to end malnutrition. GAIN launched its first large-scale fortification program in 2003, and in less than a decade has scaled its operations to reach more than 600 million people with nutritionally enhanced food. GAIN has evolved considerably as an organization, expanding beyond large-scale food fortification into new program areas, focusing on maternal, infant, and young child nutrition and improvements in agricultural practices to enhance nutrition. This paper describes GAIN's evolution from a large-scale food fortification program focus to a broader nutrition program portfolio directed toward improving access and affordability of nutritious foods for the poor. As GAIN enters its second decade, it continues to respond to the challenges of a changing nutrition landscape by introducing new programs and novel partnerships and by refining its innovative program delivery models.

RESUMO

BACKGROUND: Wheat and maize flours are widely used delivery vehicles for mass fortification. In lower-income countries, most, if not all, national-level cereal flour fortification programs routinely fortify with iron; however, cofortification with other micronutrients is common. Little information is available on the cost implications programs face when considering current fortification practices versus what the World Health Organization (WHO) interim consensus statement recommends. OBJECTIVE: The objectives of the present paper are to provide information on the costs of adding different chemical forms of iron and/or other micronutrients to premix formulations, and to discuss some of the issues that should be considered regarding which micronutrients to include in the premix. METHODS: Nine countries in Latin America, Africa, and Asia (three countries per region) that currently cofortify with multiple micronutrients including iron were selected based on low (< 75 g/day), medium (75 to 149 g/day), and high (> or = 150 g/day) mean population flour consumption levels. Premix costs per metric ton of flour produced were estimated for improving iron formulations and for following WHO recommendations for other micronutrients. RESULTS: For the selected programs to maintain current premix formulations and improve iron compounds, premix costs would increase by between 155% and 343% when the iron compound was switched from electrolytic iron to sodium iron ethylenediaminetetraacetate (NaFeEDTA), by 6% to 50% when it was switched from electrolytic iron to ferrous sulfate, and by 4% to 13 when iron addition rates were adjusted without switching the compound. To meet WHO recommendations for other micronutrients, premix costs would increase the most when the amounts of vitamins B12 and A were increased. CONCLUSIONS: For programs that currently cofortify with iron and additional micronutrients, the quality of the iron fortificant should not be overlooked simply to be able to afford to add more micronutrients to the premix. Micronutrients should be selected according to population needs, costs, and potential beneficial synergistic reactions the added micronutrients may have.

RESUMO

BACKGROUND: Fortification of staple foods has been repeatedly recommended as an effective approach to reduce micronutrient deficiencies. With the increased number of fortification projects globally, there is a need to share practical lessons learned relating to their implementation and responses to project-related and external challenges. OBJECTIVE: To document the achievements, challenges, lessons learned, and management responses associated with national fortification projects in Morocco, Uzbekistan, and Vietnam. METHODS: Independent end-of-project evaluations conducted for each project served as the primary data source and contain the history of and project activities undertaken for, each fortification project. Other sources, including national policy documents, project reports from the Global Alliance for Improved Nutrition (GAIN) and other stakeholders, industry assessments, and peer-reviewed articles, were used to document the current responses to challenges and future project plans. RESULTS: All projects had key achievements related to the development of fortification standards and the procurement of equipment for participating industry partners. Mandatory fortification of wheat flour was a key success in Morocco and Uzbekistan. Ensuring the quality of fortified foods was a common challenge experienced across the projects, as were shifts in consumption patterns and market structures. Adjustments were made to the projects' design to address the challenges faced. CONCLUSIONS: National fortification projects are dynamic and must be continually modified in response to specific performance issues and broader shifts in market structure and consumption patterns.

RESUMO

Vitamin and mineral deficiencies are ranked among the top causes of poor health and disability in the world. These deficiencies damage developing brains, impair learning ability, increase susceptibility to infections, and reduce the work productivity of nations. Food fortification is a sustainable, cost-effective approach to reducing vitamin and mineral deficiency. As the staple food for an estimated 3 billion people, rice has the potential to fill an obvious gap in current fortification programs. In recent years, new technologies have produced fortified rice kernels that are efficacious in reducing vitamin and mineral deficiency. There are opportunities to fortify a significant share of rice that comes from large mills supplying centralized markets and national welfare programs in major rice-growing countries. The rice export markets, which handle 30 million MT of rice annually, also present a key fortification opportunity. The cost of fortifying rice is only 1.5% to 3% of the current retail price of rice. Countries that mandate rice fortification have the strongest evidence for achieving wide coverage and impact. The Rice Fortification Resource Group (RiFoRG), a global network of public and private partners that offers technical and advocacy support for rice fortification, has a vision of promoting rice fortification worldwide. It has a targeted approach, engaging multisector partners in key countries where the opportunities are greatest and there is receptivity to early adoption of large-scale rice fortification. The challenges are real, the imperative to address them is powerful, and the opportunities to deliver the promise of rice fortification are clear.

RESUMO

BACKGROUND: Micronutrient deficiencies affect over 2 billion people worldwide, with profound implications for health, cognitive development, education, economic development, and productivity. Fortification of staple foods is a cost-effective strategy to increase vitamin and mineral intake among the general population. Rice is consumed by billions of people (> 440 million MT/year) but is as yet rarely fortified. OBJECTIVE: To discuss the untapped opportunity of rice fortification. METHODS: Review literature and experience with rice fortification and compare to fortification of other staple foods. RESULTS: Most technologies used to fortify rice first produce the fortified kernels and then blend them with regular, polished rice. Technologies differ with regard to how nutrients are added to the rice kernels, required investment, production cost, and degree of resemblance to unfortified rice. There are, so far, limited success stories for rice fortification. Some of the main roadblocks appear to be high initial investment and associated cost; lack of government leadership; and consumer hesitation to accept variations in the characteristics of rice, or a higher price, without good understanding of the benefits. CONCLUSIONS: In countries with a large centralized rice milling industry, starting rice fortification is easier than in countries with many small mills. Countries with large safety nets that supply rice to the poorest, for free or subsidized, have a good channel to reach those most in need. Furthermore, key players from the public and private sectors should establish a coalition to support the use of fortified rice and address some of the barriers to its implementation.

RESUMO

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.

RESUMO

OBJECTIVE: To examine the relationship between homestead food production and night blindness among pre-school children in rural Bangladesh in the presence of a national vitamin A supplementation programme. DESIGN: A cross-sectional study. SETTING: A population-based sample of six rural divisions of Bangladesh assessed in the Bangladesh Nutrition Surveillance Project 2001-2005. SUBJECTS: A total of 158 898 children aged 12-59 months. RESULTS: The prevalence rates of night blindness in children among those who did and did not receive vitamin A capsules in the last 6 months were 0·07 % and 0·13 %, respectively. Given the known effect of vitamin A supplementation on night blindness, the analysis was stratified by children's receipt of vitamin A capsules in the last 6 months. Among children who did not receive vitamin A capsules in the last 6 months, the lack of a home garden was associated with increased odds of night blindness (OR = 3·16, 95 % CI 1·76, 5·68; P = 0·0001). Among children who received vitamin A capsules in the last 6 months, the lack of a home garden was not associated with night blindness (OR = 1·28, 95 % CI 0·71, 2·31; P = 0·4). CONCLUSIONS: Homestead food production confers a protective effect against night blindness among pre-school children who missed vitamin A supplementation in rural Bangladesh.

RESUMO

BACKGROUND: Stunting is highly prevalent in developing countries and is associated with greater morbidity and mortality. Micronutrient deficiencies contribute to stunting, and micronutrient-fortified foods are a potential strategy to reduce child stunting. OBJECTIVE: To examine the relationship between the use of fortified powdered milk and noodles and child stunting in a large, population-based sample of Indonesian children. METHODS: Consumption of fortified milk and fortified noodles was assessed in children 6 to 59 months of age from 222,250 families living in rural areas and 79,940 families living in urban slum areas in Indonesia. RESULTS: The proportions of children who consumed fortified milk and fortified noodles were 34.0% and 22.0%, respectively, in rural families, and 42.4% and 48.5%, respectively, in urban families. The prevalence of stunting among children from rural and urban families was 51.8% and 48.8%, respectively. Children from rural and urban families were less likely to be stunted if they consumed fortified milk (in rural areas, OR = 0.87; 95% CI, 0.85 to 0.90; p < .0001; in urban areas, OR = 0.80; 95% CI, 0.76 to 0.85; p < .0001) or fortified noodles (in rural areas, OR = 0.95; 95% CI, 0.91 to 0.99;p = .02; in urban areas, OR = 0.95; 95% CI, 0.91 to 1.01; p = .08) in multiple logistic regression models adjusted for potential confounders. In both rural and urban families, the odds of stunting were lower when a child who consumed fortified milk also consumed fortified noodles, or when a child who consumed fortified noodles also consumed fortified milk. CONCLUSIONS: The consumption of fortified milk and noodles is associated with decreased odds of stunting among Indonesian children. These findings add to a growing body of evidence regarding the potential benefits of multiple micronutrient fortification on child growth.

RESUMO

In Bangladesh, rice prices are known to be positively associated with the prevalence of child underweight and inversely associated with household nongrain food expenditures, an indicator of dietary quality. The collection of reliable data on household expenditures is relatively time consuming and requires extensive training. Simple dietary diversity scores are increasingly used as measures of food security and as proxies for nutrient adequacy. This study examines associations between a simple dietary diversity score and commonly used indicators of socioeconomic status in Bangladesh. Data representative of rural Bangladesh was collected from 188,835 households over 18 rounds of bi-monthly data collection from 2003-2005. A simple household dietary diversity score was developed by summing the number of days each household consumed an item from each of 7 food groups over a 7-d period. The dietary diversity score was associated with per capita nongrain food expenditures (r = 0.415), total food expenditures (r = 0.327), and total household expenditures (r = 0.332) using Spearman correlations (all P < 0.0001). The frequency of meat and egg consumption showed greater variation across quintiles of total monthly expenditure than other items contributing to the dietary diversity score. After controlling for other measures of socioeconomic status in multiple linear regression models, the dietary diversity score was significantly associated with monthly per capita food and total expenditures. Low dietary diversity during the period prior to major food price increases indicates potential risk for worsening of micronutrient deficiencies and child malnutrition in Bangladesh.
