RESUMEN

INTRODUCTION: Current formulations of ready-to-use therapeutic foods (RUTFs) to treat severe acute malnutrition (SAM) in children focus on nutrient density and quantity. Less attention is given to foods targeting gut microbiota metabolism and mucosal barrier functions. Heat-stabilised rice bran contains essential nutrients, prebiotics, vitamins and unique phytochemicals that have demonstrated favourable bioactivity to modulate gut microbiota composition and mucosal immunity. This study seeks to examine the impact of RUTF with rice bran on the microbiota during SAM treatment, recovery and post-treatment growth outcomes in Jember, Indonesia. Findings are expected to provide insights into rice bran as a novel food ingredient to improve SAM treatment outcomes. METHODS AND ANALYSIS: A total of 200 children aged 6-59 months with uncomplicated SAM (weight-for-height z-scores (WHZ) <-3, or mid-upper arm circumference (MUAC) <115 mm or having bilateral pitting oedema +/++) or approaching SAM (WHZ<-2.5) will be enrolled in a double-blinded, randomised controlled trial. Children in the active control arm will receive a locally produced RUTF; those in the intervention arm will receive the local RUTF with 5% rice bran. Children will receive daily RUTF treatment for 8 weeks and be monitored for 8 weeks of follow-up. Primary outcomes include the effectiveness of RUTF as measured by changes in weight, WHO growth z-scores, MUAC and morbidity. Secondary outcomes include modulation of the gut microbiome and dried blood spot metabolome, the percentage of children recovered at weeks 8 and 12, and malnutrition relapse at week 16. An intention-to-treat analysis will be conducted for each outcome. ETHICS AND DISSEMINATION: The findings of this trial will be submitted to peer-reviewed journals and will be presented at relevant conferences. Ethics approval obtained from the Medical and Health Research Ethical Committee at the Faculty of Medicine, Public Health and Nursing, Universitas Gadjah Madain Yogyakarta Ref.

RESUMEN

BACKGROUND & AIMS: Severe acute malnutrition (SAM) is a global concern. Studies on the impact of ready-to-use therapeutic foods (RUTFs) on polyunsaturated fatty acids (PUFA) are almost non-existent. The aim was to investigate the change in whole-blood PUFA and nutrition and health markers among Cambodian children with SAM after treatment with RUTFs. METHODS: The trial was an 8-week randomised clinical trial of the effectiveness of locally produced fish-based RUTF (L-RUTF) vs standard milk-based RUFT (S-RUTF). Whole-blood fatty acids were analysed using dried blood spots. Nutrition and health markers were assessed using anthropometric assessment and blood samples for markers of inflammation. The trial was conducted at the National Pediatric Hospital, Phnom Penh, Cambodia, with one hundred and twenty-one 6-59-month-old children in treatment for SAM. RESULTS: L-RUTF had a higher content of n-3 PUFA and a higher content of arachidonic acid (AA) and docosahexaenoic acid (DHA), while S-RUTF had the highest content of n-6 PUFA. At baseline, the children presented with a Mead acid level in whole-blood of around 0.08% of total fatty acids (FA%) and an omega-3 index of ∼0.91 ± 0.44. After eight weeks of S-RUTF treatment, linoleic acid (LA), AA, n-6/n-3 PUFA ratio, and Mead acid levels were increased. The L-RUTF intervention did not change the whole-blood PUFAs from baseline. At discharge, the children in the L-RUTF group had a lower n-6/n-3 PUFA ratio than the children in the S-RUTF group, driven by a lower alpha-linolenic acid (ALA) (0.20 vs 0.27 FA%, p = 0.004) and lower LA (15.77 vs 14.21 FA%, p = 0.018) with no significant differences in AA or DHA levels. Weight-for-height z-score at discharge was negatively associated with total PUFA (ß -1.4 FA%, 95%CI. -2.7; -0.1), n-6 LCPUFA (ß -1.3 FA%, 95%CI. -1.3; -0.3), and AA (ß -0.6 FA%, 95%CI. -1.0; -0.2). Age-adjusted height was negatively associated with the Mead acid:AA ratio (ß -1.2 FA%, 95%CI. -2.2; -0.2). No significant change was seen in inflammation markers within groups or between groups during treatment, and n-3 and n-6 PUFAs were not associated with markers of inflammation or haemoglobin status at discharge. CONCLUSION: The trial found that whole-blood markers of PUFA status were low in children at admission and discharge from SAM treatment, indicating that the currently recommended composition of RUTFs are not able to correct their compromised essential fatty acid status. The higher content of DHA and AA in L-RUTF did not give rise to any improvement in PUFA status. No changes in health markers or associations between PUFA and health markers were found. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02907424.

RESUMEN

Information on fortifiable food consumption is essential to design, monitor and evaluate fortification programmes, yet detailed methods like 24-h recalls (24HRs) that provide such data are rarely conducted. Simplified questionnaire-based methods exist but their validity compared with 24HRs has not been shown. We compared two simplified methods (i.e., a household food acquisition and purchase questionnaire [FAPQ] and a 7-day semiquantitative food frequency questionnaire [SQ-FFQ]) against 24HRs for estimating fortifiable food consumption. We assessed the consumption of fortifiable wheat flour and oil using a FAPQ and, for wheat flour only, a 7-day SQ-FFQ and compared the results against 24HRs. The participants included children 12-18 months (n = 123) and their mothers 18-49 years selected for a study assessing child vitamin A intake and status in Mandaluyong City, Philippines. For fortifiable wheat flour, the FAPQ estimated considerably lower mean intakes compared to 24HRs for children and mothers (2.2 vs. 14.1 g/day and 5.1 vs. 42.3 g/day, respectively), while the SQ-FFQ estimated slightly higher mean intakes (15.7 vs. 14.1 g/day and 51.5 vs. 42.3 g/day, respectively). For fortifiable oil, the FAPQ estimated considerably higher mean intakes compared to 24HRs for children and mothers (4.6 vs. 1.8 g/day and 12.5 vs. 6.1 g/day, respectively). The SQ-FFQ, but not the FAPQ, generated useful information on fortifiable food consumption that can inform fortification programme design and monitoring decisions in the absence of more detailed individual-level data. Potential adaptations to improve the FAPQ, such as additional questions on foods prepared away from home and usage patterns, merit further research.

RESUMEN

We estimated how micronutrient needs of young children, aged 6-24 months were covered by the standard (traditional) diets in Ghana and Benin, and the contributions of partial breastfeeding and national nutrition programs aimed at improving micronutrient status to overall micronutrient intakes. Estimates of micronutrient intake from standard diets were based on previous surveys, using the food composition table of West Africa (INFOOD). Recommended micronutrient intakes were based on World Health Organization recommendations. Children were grouped in three age groups (6-8, 9-12, and 13-24 months) to capture the changing dynamics of the complementary feeding period. As expected, from 6 months of age onwards, breastmilk didn't cover the micronutrient needs. The standard diets contributed only minimal to micronutrient intakes of children ranging from 0% to 37% of recommended intakes for Ca, Fe, Zn, vitamin A, vitamin D and iodine depending on the micronutrient considered. The contribution of mass (bio)-fortification programs to the coverage of micronutrient needs varied widely, depending on the staple food considered and the country, but overall did not allow to fill the gap in micronutrient needs of children except for vitamin A in some contexts. In contrast, consumption of voluntary fortified complementary food, especially formulated for the needs in this age groups, contributed substantially to overall micronutrient intake and could fill the gap for several micronutrients. The development of young child-targeted programs including micronutrient-dense foods, associated with interventions to increase the diet diversity and meal frequency, could significantly improve micronutrients intakes of children in both Ghana and Benin.

RESUMEN

Women reliant on mostly rice-based diets can have inadequate thiamine intake, placing breastfed infants at risk of thiamine deficiency and, in turn, physical and cognitive impairments. We investigated the impact of maternal thiamine supplementation doses on infants' cognitive, motor, and language development across the first year. In this double-blind, four-parallel-arm, randomized controlled trial, healthy mothers of exclusively breastfed newborn infants were recruited in Kampong Thom, Cambodia. At 2 weeks postnatal, women (n = 335) were randomized to one of four treatment groups to consume one capsule/day with varying amounts of thiamine for 22 weeks: 0, 1.2, 2.4, and 10 mg. At 2, 12, 24, and 52 weeks of age, infants were assessed with the Mullen Scales of Early Learning (MSEL) and the Caregiver Reported Early Development Instrument (CREDI). Multiple regression and mixed effects modeling suggest that by 6 months of age, the highest maternal thiamine dose (10 mg/day) held significant benefits for infants' language development, but generally not for motor or visual reception development. Despite having achieved standardized scores on the MSEL that approximated U.S. norms by 6 months, infants showed a significant drop relative to these norms in both language domains following trial completion, indicating that nutritional interventions beyond 6 months may be necessary.

RESUMEN

BACKGROUND: Infantile beriberi-related mortality is still common in South and Southeast Asia. Interventions to increase maternal thiamine intakes, and thus human milk thiamine, are warranted; however, the required dose remains unknown. OBJECTIVES: We sought to estimate the dose at which additional maternal intake of oral thiamine no longer meaningfully increased milk thiamine concentrations in infants at 24 wk postpartum, and to investigate the impact of 4 thiamine supplementation doses on milk and blood thiamine status biomarkers. METHODS: In this double-blind, 4-parallel arm randomized controlled dose-response trial, healthy mothers were recruited in Kampong Thom, Cambodia. At 2 wk postpartum, women were randomly assigned to consume 1 capsule, containing 0, 1.2 (estimated average requirement), 2.4, or 10 mg of thiamine daily from 2 through 24 weeks postpartum. Human milk total thiamine concentrations were measured using HPLC. An Emax curve was plotted, which was estimated using a nonlinear least squares model in an intention-to-treat analysis. Linear mixed-effects models were used to test for differences between treatment groups. Maternal and infant blood thiamine biomarkers were also assessed. RESULTS: In total, each of 335 women was randomly assigned to1 of the following thiamine-dose groups: placebo (n = 83), 1.2 mg (n = 86), 2.4 mg (n = 81), and 10 mg (n = 85). The estimated dose required to reach 90% of the maximum average total thiamine concentration in human milk (191 µg/L) is 2.35 (95% CI: 0.58, 7.01) mg/d. The mean ± SD milk thiamine concentrations were significantly higher in all intervention groups (183 ± 91, 190 ± 105, and 206 ± 89 µg/L for 1.2, 2.4, and 10 mg, respectively) compared with the placebo group (153 ± 85 µg/L; P < 0.0001) and did not significantly differ from each other. CONCLUSIONS: A supplemental thiamine dose of 2.35 mg/d was required to achieve a milk total thiamine concentration of 191 µg/L. However, 1.2 mg/d for 22 wk was sufficient to increase milk thiamine concentrations to similar levels achieved by higher supplementation doses (2.4 and 10 mg/d), and comparable to those of healthy mothers in regions without beriberi. This trial was registered at clinicaltrials.gov as NCT03616288.

RESUMEN

Thiamine (vitamin B1 ) is an essential micronutrient in energy metabolism and cognitive and neurological health. Thiamine deficiency disorders (TDDs) have a range of clinical presentations that result in various morbidities and can be fatal if not promptly recognized and treated, especially in infants. To intervene, thiamine intakes by breastfeeding mothers and others at risk of thiamine deficiency should be increased to ensure adequate thiamine intake. Although thiamine fortification programs have a long history in high-income countries, there are few mandatory fortification programs to address TDDs in low- and middle-income countries (LMICs), particularly in the regions of greatest concern, South and Southeast Asia. This review highlights essential aspects for consideration in the development of a mandatory fortification program in LMICs, including an overview of the data required to model fortification dosing schemes, available thiamine fortificants, and potential fortification vehicles, as well as identifies current knowledge gaps.

RESUMEN

Thiamine deficiency is a public health issue in Cambodia. Thiamine fortification of salt has been proposed; however, the salt intake of lactating women, the target population, is currently unknown. We estimated salt intakes among lactating women (<6 months postpartum) using three methods: repeat observed-weighed intake records and 24-h urinary sodium excretions (n = 104), and household salt disappearance (n = 331). Usual salt intake was estimated by adjusting for intraindividual intakes using the National Cancer Institute method, and a thiamine salt fortification scenario was modeled using a modified estimated average requirement (EAR) cut-point method. Unadjusted salt intake from observed intakes was 9.3 (8.3-10.3) g/day, which was not different from estimated salt intake from urinary sodium excretions, 9.0 (8.4-9.7) g/day (P = 0.3). Estimated salt use from household salt disappearance was 11.3 (10.7-11.9) g/person/day. Usual (adjusted) salt intake from all sources was 7.7 (7.4-8.0) g/day. Assuming no stability losses, a modeled fortification dose of 275 mg thiamine/kg salt could increase thiamine intakes from fortified salt to 2.1 (2.0-2.2) mg/day, with even low salt consumers reaching the EAR of 1.2 mg/day from fortified salt alone. These findings, in conjunction with future sensory and stability research, can inform a potential salt fortification program in Cambodia.

RESUMEN

BACKGROUND: Food fortification is implemented to increase intakes of specific nutrients in the diet, but contributions of fortified foods to nutrient intakes are rarely quantified. OBJECTIVES: We quantified iron, vitamin A, and iodine intakes from fortified staple foods and condiments among women of reproductive age (WRA). METHODS: In subnational (Nigeria, South Africa) and national (Tanzania, Uganda) cross-sectional, clustered household surveys, we assessed fortifiable food consumption. We estimated daily nutrient intakes from fortified foods among WRA by multiplying the daily apparent fortifiable food consumption (by adult male equivalent method) by a fortification content for the food. Two fortification contents were used: measured, based on the median amount quantified from individual food samples collected from households; and potential, based on the targeted amount in national fortification standards. Results for both approaches are reported as percentages of the estimated average requirement (EAR) and recommended nutrient intake (RNI). RESULTS: Fortified foods made modest contributions to measured iron intakes (0%-13% RNI); potential intakes if standards are met were generally higher (0%-65% RNI). Fortified foods contributed substantially to measured vitamin A and iodine intakes (20%-125% and 88%-253% EAR, respectively); potential intakes were higher (53%-655% and 115%-377% EAR, respectively) and would exceed the tolerable upper intake level among 18%-56% of WRA for vitamin A in Nigeria and 1%-8% of WRA for iodine in Nigeria, Tanzania, and Uganda. CONCLUSIONS: Fortified foods are major contributors to apparent intakes of vitamin A and iodine, but not iron, among WRA. Contributions to vitamin A and iodine are observed despite fortification standards not consistently being met and, if constraints to meeting standards are addressed, there is risk of excessive intakes in some countries. For all programs assessed, nutrient intakes from all dietary sources and fortification standards should be reviewed to inform adjustments where needed to avoid risk of low or excessive intakes.

RESUMEN

OBJECTIVE: To measure fatty acid composition, particularly whole-blood PUFA content, in acutely malnourished children and identify associations with markers of nutritional and health status. DESIGN: PUFA were assessed in dried blood spots obtained from a cross-sectional study. Nutritional and health status were assessed by anthropometry, haemoglobinopathies, inflammation and blood counts. SETTING: Cambodia. PARTICIPANTS: The study was conducted with 174 children aged 0·5-18 years with acute malnutrition. RESULTS: Among total fatty acids (FA), the relative percentage of total PUFA was 20 % FA, with 14 % of the children having very low PUFA (mead acid (MA):arachidonic acid (AA) >0·02, n-6 docosapentaenoic acid:DHA >0·2 and total n-6:n-3 PUFA >10·5). Wasting was not associated with any PUFA. Stunting and low height were consistently positively associated with total PUFA and positively with n-6 PUFA. Height was positively associated with n-3 long-chain PUFA (LCPUFA). The presence of haemoglobinopathies or inflammation was positively associated with MA:AA, but not total PUFA. Elevated blood platelet counts were positively correlated with linoleic acid and appeared to be influenced by anaemia (P = 0·010) and inflammation (P = 0·002). Monocyte counts were high during inflammation (P = 0·052) and correlated positively with n-6 LCPUFA and n-3 LCPUFA. CONCLUSIONS: Children with acute malnutrition or stunting had low PUFA, while elevated platelets and monocytes were associated with high PUFA. In acutely malnourished children, inflammation could lead to elevated blood cell counts resulting in increased whole-blood PUFA which does not reflect dietary intake or nutritional status.

RESUMEN

This cluster randomised controlled trial tested the effectiveness of a locally produced, fish-based, ready-to-use supplementary food (RUSF) to prevent growth faltering (decline in z-scores). Cambodian infants (n= 485), aged 6 to 11 months, were randomised by site to receive the RUSF, Corn-Soy Blend++ (CSB++), micronutrient powders (MNP), or no supplement (control). The intervention was for 6 months. In unadjusted analysis, the control group had statistically significantly decreased weight-for-age z-scores (WAZ; -0.02, 95%CI = -0.03 - -0.01, P= 0.001) and height-for-age z-scores (HAZ; -0.07, 95%CI = -0.09 - -0.05, P < 0.001), and increased mid-upper arm-circumference (MUAC; 0.02cm, 95%CI = 0.01 - 0.04, P = 0.010), but no statistically significant change in weight-for-height z-scores (WHZ). The RUSF group did not differ significantly from the control for WAZ, HAZ or WHZ (in other words, WAZ and HAZ decreased and WHZ did not change), but had increased MUAC in comparison to the control (0.04cm, 95%CI = 0.01 - 0.06, P = 0.008). There were no statistically significant differences between the RUSF group and the CSB++ or MNP groups with respect to WAZ, HAZ, WHZ or MUAC. Interestingly, in adjusted analysis, low consumers of RUSF had increased WAZ, WHZ and MUAC (0.03, 95%CI = 0.01-0.06, P = 0.006; 0.04, 95%CI = 0.01-0.08, P = 0.026; and 0.05cm, 95%CI = 0.02-0.09, P = 0.004, respectively) compared with the control. The novel RUSF, particularly in small quantities, protected against ponderal growth faltering, but the improvements were of limited clinical significance.

RESUMEN

BACKGROUND: Within Cambodia, micronutrient deficiencies continue to be prevalent in vulnerable groups, such as women and children. Fortification of staple foods such as rice could be a promising strategy for Cambodia to improve micronutrient status. OBJECTIVE: Our objective was to investigate the impact of multiple-micronutrient fortified rice (MMFR), distributed through a World Food Program school-meals program (WFP-SMP) on serum zinc concentrations and folate status in a double-blind, cluster-randomized, placebo-controlled trial. METHODS: Sixteen schools were randomly assigned to receive one of three different types of extruded-fortified rice (UltraRice Original (URO), UltraRice New (URN), or NutriRice) or unfortified rice (placebo) six days a week for six months. A total of 1950 schoolchildren (6-16 years old) participated in the study. Serum zinc (all groups) and folate (only in NutriRice and placebo group) concentrations were assessed from morning non-fasting antecubital blood samples and were measured at three time points (baseline and after three and six months). RESULTS: After six months of intervention, serum zinc concentrations were significantly increased in all fortified rice group compared to placebo and baseline (0.98, 0.85 and 1.40 µmol/L for URO, URN and NutriRice, respectively) (interaction effect: p < 0.001 for all). Children in the intervention groups had a risk of zinc deficiencies of around one third (0.35, 039, and 0.28 for URO, URN, and NutriRice, respectively) compared to the placebo (p < 0.001 for all). The children receiving NutriRice had higher serum folate concentrations at endline compared to children receiving normal rice (+ 2.25 ng/mL, p = 0.007). CONCLUSIONS: This study showed that the high prevalence of zinc and folate deficiency in Cambodia can be improved through the provision of MMFR. As rice is the staple diet for Cambodia, MMFR should be considered to be included in the school meal program and possibilities should be explored to introduce MMFR to the general population.

RESUMEN

BACKGROUND: Rates of childhood undernutrition are persistently high in Cambodia. Existing ready-to-use supplementary and therapeutic foods (RUSFs and RUTFs) have had limited acceptance and effectiveness. Therefore, our project developed and trialled a locally-produced, multiple micronutrient fortified lipid-based nutrient supplement (LNS) with therapeutic and supplementary versions. This ready-to-use food (RUF) is innovative in that, unlike many RUFs, it contains fish instead of milk. Development began in 2013 and the RUF was finalised in 2015. From 2015 until the present, both the RUTF and the RUSF versions were trialled for acceptability and effectiveness. METHODS: This paper draws on project implementation records and semi-structured interviews to describe the partnership between the Cambodian Ministries of Health and Agriculture, Forestry and Fisheries, UNICEF, the French National Research Institute for Sustainable Development (IRD), universities, and Vissot factory. It discusses the project implementation and lessons learned from the development and trialling process, and insights into positioning nutrition on the health agenda in low and middle-income countries. RESULTS: The lessons learned relate to the importance of project planning, management, and documentation in order to seize opportunities in the research, policy, advocacy, and programming environment while ensuring adequate day-to-day project administration and resourcing. CONCLUSIONS: We conclude that projects such as ours, that collaborate to develop and test novel, locally-produced RUTFs and RUSFs, offer an exciting opportunity to respond to both local programmatic and broader research needs.

RESUMEN

INTRODUCTION: Thiamine (vitamin B1) deficiency remains a concern in Cambodia where women with low thiamine intake produce thiamine-poor milk, putting their breastfed infants at risk of impaired cognitive development and potentially fatal infantile beriberi. Thiamine fortification of salt is a potentially low-cost, passive means of combating thiamine deficiency; however, both the dose of thiamine required to optimise milk thiamine concentrations as well as usual salt intake of lactating women are unknown. METHODS AND ANALYSIS: In this community-based randomised controlled trial, 320 lactating women from Kampong Thom, Cambodia will be randomised to one of four groups to consume one capsule daily containing 0, 1.2, 2.4 or 10 mg thiamine as thiamine hydrochloride, between 2 and 24 weeks postnatal. The primary objective is to estimate the dose where additional maternal intake of thiamine no longer meaningfully increases infant thiamine diphosphate concentrations 24 weeks postnatally. At 2, 12 and 24 weeks, we will collect sociodemographic, nutrition and health information, a battery of cognitive assessments, maternal (2 and 24 weeks) and infant (24 weeks only) venous blood samples (biomarkers: ThDP and transketolase activity) and human milk samples (also at 4 weeks; biomarker: milk thiamine concentrations). All participants and their families will consume study-provided salt ad libitum throughout the trial, and we will measure salt disappearance each fortnight. Repeat weighed salt intakes and urinary sodium concentrations will be measured among a subset of 100 participants. Parameters of Emax dose-response curves will be estimated using non-linear least squares models with both 'intention to treat' and a secondary 'per-protocol' (capsule compliance ≥80%) analyses. ETHICS AND DISSEMINATION: Ethical approval was obtained in Cambodia (National Ethics Committee for Health Research 112/250NECHR), Canada (Mount Saint Vincent University Research Ethics Board 2017-141) and the USA (University of Oregon Institutional Review Board 07052018.008). Results will be shared with participants' communities, as well as relevant government and scientific stakeholders via presentations, academic manuscripts and consultations. TRIAL REGISTRATION NUMBER: NCT03616288.

RESUMEN

In Cambodia, existing food products for treating or preventing undernutrition have met with limited success. Therefore, in 2014, alternative ready-to-use foods were developed. This trial aimed to assess the acceptability of the novel ready-to-use supplementary food (RUSF) as a snack or mixed with borbor (white rice porridge), compared with corn-soy blend plus plus (CSB++) and borbor fortified with micronutrient powder (MNP). The nonblinded, randomised 4 × 4 crossover trial recruited 95 children aged 9-23 months from communities in peri-urban Phnom Penh. Small quantities (100 g for porridges, 42 g for snack) of each food were offered for three consecutive days at testing sites (homes of health volunteers). Main outcomes were children's consumption, caregivers' assessment of children's preferences, and caregivers' ranking of the foods. Median percentage consumed of the test food servings ranged from 21 to 50% (p = 0.003). The odds of children consuming over 50% were greatest for borbor fortified with MNP versus RUSF snack (unadjusted OR = 6.79, CI = 2.80-16.47, p < 0.001). However, the median energy children received when consuming the RUSF with borbor (57 kcals) or as a snack (48 kcals) was greater than with CSB++ (15 kcals) or borbor fortified with MNP (18 kcals; p < 0.001). Therefore, although children ate less RUSF, it provided approximately three times more kilocalories. Caregivers reported that their children had the highest preference for borbor fortified with MNP. Caregivers themselves ranked the novel RUSF snack highest. Thus, the innovative RUSF was considered sufficiently acceptable to proceed to an effectiveness trial.

RESUMEN

BACKGROUND: Despite scientific evidence on the potential impact or importance of specific interventions to improve micronutrient status of vulnerable groups, political commitment and extensive support from national stakeholders is paramount to support introduction and implementation of these interventions at national level. In order to develop efficient nutritional strategies to improve the micronutrient status of children < 5 years of age and women of reproductive age that will be supported by a wide range of stakeholders, a better understanding of viewpoints on the nutrition politics and strategies is necessary. Multi-criteria mapping (MCM) was successfully used to assess the stakeholder's viewpoint in a wide variety of contexts since the late 1990s. OBJECTIVE: The objective of the present study was to assess the viewpoints of stakeholders on a wide range of potential nutritional interventions in the five Southeast Asian countries participating in the SMILING project. METHOD: MCM methodology was used to appraise the stakeholder's viewpoints in five countries. RESULTS: The results show that the overall stakeholders' preference was for actions already implemented in their country rather than for new, innovative options, even for supplementation. Indirect interventions such like food fortification (except in Indonesia), delayed cord clamping or food-based approaches were generally less favored by the stakeholders. However, the majority of stakeholders agreed that new approaches should be considered and put in place in the future provided that evidence of their impact was demonstrated, that they received adequate technical support for their implementation and their monitoring, and that they will be accompanied by strong advocacy among decision-makers, civil society and beneficiaries. CONCLUSIONS FOR PRACTICE: To conclude, for the introduction of new, innovative strategies to reduce micronutrient deficiencies in South-East Asia, convincing stakeholders appears to be the first hurdle to be taken.

RESUMEN

Objectives To provide an overview of nutrition-specific and nutrition-sensitive interventions that could improve micronutrient status of women of reproductive age. Methods This narrative review has a special focus on Southeast Asia, as the work was undertaken within the framework of the SMILING (Sustainable Micronutrient Interventions to controL deficiencies and Improve Nutrition status and General health in Southeast Asia) project. Results In order for new interventions to become accepted, comprehension and interpretation of potential impact of different strategies by policymakers and non-nutritionists is needed. By presenting a wide overview of strategies, and discussing the context and current consensus on these strategies, the review aims to help with the formulation of new recommendations for national programs in Southeast Asia. Conclusions Current policies in Southeast Asia to improve micronutrient status of women of reproductive age are focused too much on single micronutrient supplementation for pregnant women (iron and folic acid supplements). A more holistic approach, including both nutrition-specific and nutrition-sensitive interventions, is needed.

RESUMEN

The impact of freshwater fish consumption on the status of long-chain n-3 fatty acids (n-3 LCPUFA) in infants in landlocked, low-income populations is unknown. We used secondary data from a randomized, single-blinded, controlled trial to evaluate the impact of daily consumption of complementary food products with small amounts of freshwater fish on whole blood n-3 LCPUFA in Cambodian infants. Infants (n = 419), received daily, one of four food products for 9 months. Two products contained freshwater fish: WinFood (10% fish by dry weight) and WinFood-L (12% fish by dry weight), while two products were non-fish-based: corn-soy blends (CSB+ and CSB++). Whole blood fatty acids and breastfeeding status were assessed at baseline and endline of the intervention. The WinFood products contributed to an estimated maximum intake of 86.5 mg/day n-3 LCPUFA. There was no difference in whole blood n-3 LCPUFA among the four intervention groups or between the fish-based and the non-fish-based groups (p ≥ 0.142). At endline, 71% of the children were still breastfed. Interaction analyses indicated a lower ratio of n-6/n-3 PUFA in non-breastfed infants in the WinFood groups compared to the CSB groups (pinteraction = 0.026). Thus, a high intake of n-3 LCPUFA from breastmilk may have blurred a potential impact of small amounts of freshwater fish effect on n-3 LCPUFA status in Cambodian infants.

RESUMEN

BACKGROUND: Existing ready-to-use supplementary and therapeutic foods (RUSFs and RUTFs) have had limited acceptance and effectiveness in Cambodia. This has hampered the treatment and prevention of child malnutrition. An innovative, locally produced, multiple micronutrient fortified lipid-based nutrient supplement (LNS) has been developed for use as an RUSF. Unlike most RUSFs, which contain milk, this product contains fish as the animal protein. Few RUSFs have been formulated using non-milk animal-source foods and they have not been widely tested. An acceptability trial that was conducted on this novel RUSF in June 2015 demonstrated that children will eat the RUSF and that caregivers will feed it to their children. The current trial aims to evaluate the effectiveness of the RUSF in preventing growth faltering and improving micronutrient status in Cambodian children. METHODS AND ANALYSIS: This trial is a six-month, prospective, cluster randomised, non-blinded controlled trial among infants in peri-urban Phnom Penh. The trial aims to establish the superiority of the novel RUSF, compared to three alternatives (Corn-Soy Blend Plus Plus (CSB++) and Sprinkles micronutrient powders as active comparators, and the unimproved diet as a control). The allocation ratio is 1:1. Healthy children (N = 540) aged six to eleven months will be recruited. Data will be collected at baseline, and monthly thereafter for a period of six months. Participants will be provided with a monthly supply of the food to which their village has been allocated. DISCUSSION: There is an urgent need to develop locally produced and culturally acceptable RUSFs, and to compare these with existing options in terms of their potential for preventing malnutrition, in Cambodia and elsewhere. This trial will contribute much-needed data on the effectiveness of supplementary foods with an animal-source food other than milk, by comparing a novel RUSF based on fish to one that uses milk (CSB++). Moreover, it will deepen the understanding of the impact of multiple micronutrients provided with or without macronutrients, by comparing the novel RUSF and CSB++, which combine macronutrients with multiple micronutrients, to Sprinkles, which contains no macronutrients. In addition, it will augment the body of evidence from Asia. TRIAL REGISTRATION: ClinicalTrials.gov, Identifier: LNS-CAMB-INFANTS-EFF; NCT02257762 .
