Effectiveness of a nonweight-based daily dosage of ready-to-use therapeutic food in children suffering from uncomplicated severe acute malnutrition: A nonrandomized, noninferiority analysis of programme data in Afghanistan.

Severe acute malnutrition (SAM) remains a major global public health problem. SAM cases are treated using ready-to-use therapeutic food (RUTF) at a dosage of ∼200 kcal/kg/day per the standard treatment protocol (STD). Emerging evidence on simplifications to the standard protocol, which among other adaptations, includes reducing the daily RUTF dosage, indicates that it is effective and safe for treating children with SAM. In response to a foreseen stock shortage of RUTF, the government of Afghanistan endorsed the temporary use of a modified treatment protocol in which the daily RUTF dosage was prescribed at 1000 kcal/day (irrespective of body weight) until the child achieved moderate acute malnutrition status (weight-for-height z-score ≥ -3 or mid-upper arm circumference [MUAC] ≥ 115 mm), at which point 500 kcal/day was prescribed until cured (modified treatment protocol [MTP]). In this paper, we report the results of this nonweight-based daily RUTF dosage experience. Data of 2042 children with SAM, treated using either the STD protocol (n = 269) or the MTP protocol (n = 1773) from August 2019 to March 2021 in five provinces, were analyzed. The per-protocol analyses confirmed noninferiority of MTP protocol when compared to STD protocol for recovery rate [93.3% vs. 90.2%; ∆ (95% confidence interval, CI) = 3.1 (-0.9; 7.2) %] and length-of-stay [82.6 vs. 75.6 days; ∆ (95% CI) = 6.9 (3.3; 10.5) days], considering the margin of noninferiority of -10% and +14 days, respectively. Weight gain velocity was smaller in the MTP protocol group than in the STD protocol group [3.7 (1.7) vs. 5.2 (2.9) g/kg/day; ∆ (95% CI) = -1.5 (-1.8, -1.2); p < 0.001]. The STD group had a significantly higher mean than the MTP group for absolute MUAC gain [∆ (95% CI) = 1.7 (1.0; 2.3) mm; p < 0.001] and the MUAC velocity [∆ (95% CI) = 0.29 (0.20; 0.37) mm/week; p < 0.001]. Our results confirm the noninferiority of a nonweight-based daily dosage and support the endorsement of this modification as an alternative to the standard protocol in resource-constrained contexts.

Anthropometric criteria for best-identifying children at high risk of mortality: a pooled analysis of twelve cohorts.

OBJECTIVE: To understand which anthropometric diagnostic criteria best discriminate higher from lower risk of death in children and explore programme implications. DESIGN: A multiple cohort individual data meta-analysis of mortality risk (within 6 months of measurement) by anthropometric case definitions. Sensitivity, specificity, informedness and inclusivity in predicting mortality, face validity and compatibility with current standards and practice were assessed and operational consequences were modelled. SETTING: Community-based cohort studies in twelve low-income countries between 1977 and 2013 in settings where treatment of wasting was not widespread. PARTICIPANTS: Children aged 6 to 59 months. RESULTS: Of the twelve anthropometric case definitions examined, four (weight-for-age Z-score (WAZ) <-2), (mid-upper arm circumference (MUAC) <125 mm), (MUAC < 115 mm or WAZ < -3) and (WAZ < -3) had the highest informedness in predicting mortality. A combined case definition (MUAC < 115 mm or WAZ < -3) was better at predicting deaths associated with weight-for-height Z-score <-3 and concurrent wasting and stunting (WaSt) than the single WAZ < -3 case definition. After the assessment of all criteria, the combined case definition performed best. The simulated workload for programmes admitting based on MUAC < 115 mm or WAZ < -3, when adjusted with a proxy for required intensity and/or duration of treatment, was 1·87 times larger than programmes admitting on MUAC < 115 mm alone. CONCLUSIONS: A combined case definition detects nearly all deaths associated with severe anthropometric deficits suggesting that therapeutic feeding programmes may achieve higher impact (prevent mortality and improve coverage) by using it. There remain operational questions to examine further before wide-scale adoption can be recommended.

How do children with severe underweight and wasting respond to treatment? A pooled secondary data analysis to inform future intervention studies.

Children with weight-for-age z-score (WAZ) <-3 have a high risk of death, yet this indicator is not widely used in nutrition treatment programming. This pooled secondary data analysis of children aged 6-59 months aimed to examine the prevalence, treatment outcomes, and growth trajectories of children with WAZ <-3 versus children with WAZ ≥-3 receiving outpatient treatment for wasting and/or nutritional oedema, to inform future protocols. Binary treatment outcomes between WAZ <-3 and WAZ ≥-3 admissions were compared using logistic regression. Recovery was defined as attaining mid-upper-arm circumference ≥12.5 cm and weight-for-height z-score ≥-2, without oedema, within a period of 17 weeks of admission. Data from 24,829 children from 9 countries drawn from 13 datasets were included. 55% of wasted children had WAZ <-3. Children admitted with WAZ <-3 compared to those with WAZ ≥-3 had lower recovery rates (28.3% vs. 48.7%), higher risk of death (1.8% vs. 0.7%), and higher risk of transfer to inpatient care (6.2% vs. 3.8%). Growth trajectories showed that children with WAZ <-3 had markedly lower anthropometry at the start and end of care, however, their patterns of anthropometric gains were very similar to those with WAZ ≥-3. If moderately wasted children with WAZ <-3 were treated in therapeutic programmes alongside severely wasted children, we estimate caseloads would increase by 32%. Our findings suggest that wasted children with WAZ <-3 are an especially vulnerable group and those with moderate wasting and WAZ <-3 likely require a higher intensity of nutritional support than is currently recommended. Longer or improved treatment may be necessary, and the timeline and definition of recovery likely need review.

Anthropometric deficits and the associated risk of death by age and sex in children aged 6-59 months: A meta-analysis.

Risk of death from undernutrition is thought to be higher in younger than in older children, but evidence is mixed. Research also demonstrates sex differences whereby boys have a higher prevalence of undernutrition than girls. This analysis described mortality risk associated with anthropometric deficits (wasting, underweight and stunting) in children 6-59 months by age and sex. We categorised children into younger (6-23 months) and older (24-59 months) age groups. Age and sex variations in near-term (within 6 months) mortality risk, associated with individual anthropometric deficits were assessed in a secondary analysis of multi-country cohort data. A random effects meta-analysis was performed. Data from seven low-or-middle-income-countries collected between 1977 and 2013 were analysed. One thousand twenty deaths were recorded for children with anthropometric deficits. Pooled meta-analysis estimates showed no differences by age in absolute mortality risk for wasting (RR 1.08, p = 0.826 for MUAC < 125 mm; RR 1.35, p = 0.272 for WHZ < -2). For underweight and stunting, absolute risk of death was higher in younger (RR 2.57, p < 0.001) compared with older children (RR 2.83, p < 0.001). For all deficits, there were no differences in mortality risk for girls compared with boys. There were no differences in the risk of mortality between younger and older wasted children, supporting continued inclusion of all children under-five in wasting treatment programmes. The risk of mortality associated with underweight and stunting was higher among younger children, suggesting that prevention programmes might be justified in focusing on younger children where resources are limited. There were no sex differences by age in mortality risk for all deficits.

Incidence of severe acute malnutrition after treatment: A prospective matched cohort study in Sokoto, Nigeria.

Severe acute malnutrition (SAM) among children in Nigeria is tackled through the outpatient therapeutic programme (OTP) of the Community-based Management of Acute Malnutrition (CMAM) programme. CMAM is evidently effective in resolving SAM, but little evidence exists on the remaining risk of SAM relapse for children discharged as cured from the OTP. We aimed to measure and compare the 6-month incidence of SAM among OTP-cured and community control children and identify factors associated with SAM relapse. We conducted a prospective matched cohort study that tracked 553 OTP-cured and 526 control children in Sokoto State, Northern Nigeria. Outcomes and covariates were measured fortnightly in up to 12 home visits. We used multivariate Cox and accelerated failure time models to identify significant risk correlates, where the covariates to be tested for correlation with relapse were selected using domain knowledge and automatic feature selection methods. SAM incidence rates were 52 times higher in the OTP-cured cohort (0.204/100 child-days) than in the community control cohort (0.004/100 child-days). Children with lower mid-upper arm circumference at OTP admission, with lower height/length-for-age z-scores, whose household head did not work over the full year, who lived in an area previously affected by environmental shocks, who were female and who had diarrhoea before the visit had a significantly higher relapse risk. Our study shows that OTP-cured children remain at a significantly excess risk of SAM. To improve long-term health outcomes of these children, programmes adopting a CMAM approach should strengthen follow-up care and be integrated with other preventive services.

Determining a global mid-upper arm circumference cut-off to assess underweight in adults (men and non-pregnant women).

OBJECTIVE: To determine if a global mid-upper arm circumference (MUAC) cut-off can be established to classify underweight in adults (men and non-pregnant women). DESIGN: We conducted an individual participant data meta-analysis (IPDMA) to explore the sensitivity (SENS) and specificity (SPEC) of various MUAC cut-offs for identifying underweight among adults (defined as BMI < 18·5 kg/m2). Measures of diagnostic accuracy were determined every 0·5 cm across MUAC values from 19·0 to 26·5 cm. A bivariate random effects model was used to jointly estimate SENS and SPEC while accounting for heterogeneity between studies. Various subgroup analyses were performed. SETTING: Twenty datasets from Africa, South Asia, Southeast Asia, North America and South America were included. PARTICIPANTS: All eligible participants from the original datasets were included. RESULTS: The total sample size was 13 835. Mean age was 32·6 years and 65 % of participants were female. Mean MUAC was 25·7 cm, and 28 % of all participants had low BMI (<18·5 kg/m2). The area under the receiver operating characteristic curve for the pooled dataset was 0·91 (range across studies 0·61-0·98). Results showed that MUAC cut-offs in the range of ≤23·5 to ≤25·0 cm could serve as an appropriate screening indicator for underweight. CONCLUSIONS: MUAC is highly discriminatory in its ability to distinguish adults with BMI above and below 18·5 kg/m2. This IPDMA is the first step towards determining a global MUAC cut-off for adults. Validation studies are needed to determine whether the proposed MUAC cut-off of 24 cm is associated with poor functional outcomes.

Soya, maize and sorghum ready-to-use therapeutic foods are more effective in correcting anaemia and iron deficiency than the standard ready-to-use therapeutic food: randomized controlled trial.

BACKGROUND: The prevalence of anaemia and iron deficiency (ID) among children with severe acute malnutrition (SAM) and their correction during nutritional rehabilitation are not well documented. This study assessed anaemia and ID prevalence and their predictors at start of SAM treatment, and the efficacy of their treatment and effect on gut health of two novel Ready-To-Use Therapeutic foods (RUTF) prepared from soybean, maize and sorghum (SMS) with (MSMS-RUTF) or without added milk (FSMS-RUTF) compared to those of the standard formulation prepared from peanut and milk (PM-RUTF). METHODS: This was a 3-arms parallel groups, simple randomised, controlled non-inferiority trial in 6-59 months old Central Malawian children with SAM. Anaemia was defined using altitude- and ethnicity-adjusted haemoglobin. Iron status was defined using soluble transferrin receptor (sTfR) and body iron stores (BIS). We used Pearson's chi-square test, t-test for paired or unpaired data, Kruskal-Wallis test for between-arm differences as appropriate and logistic regression to identify independent predictors of anaemia or iron deficiency anaemia (IDA). RESULTS: The sample size was 389. At admission, the prevalence [%(95%CI)] of anaemia was 48.9(41.4-56.5)% while that of ID and IDA were 55.7(48.6-62.5)% and 34.3(28.2-41.0)% when using sTfR criterion and 29.1(24.4-34.4)% and 28.9(23.7-34.9)% when using BIS criterion, respectively. At discharge, nutrition rehabilitation with SMS-RUTF was associated with the lowest prevalence of anaemia [12.0(6.9-20.3)% for FSMS-RUTF, 18.2(11.9-26.8)% for MSMS-RUTF and 24.5(15.8-35.9)% for PM-RUTF; p = 0.023] and IDA [7.9(3.4-17.3)% for FSMS-RUTF, 10.9(4.8-22.6)% for MSMS-RUTF and 20.5(10.7-35.5)% for PM-RUTF; p = 0.028]. SMS-RUTF was also associated with the highest increase in BIS [Change in BIS (95%CI)] among the iron deplete at admission [6.2 (3.7; 8.6), 3.2 (0.8; 5.6), 2.2 (0.2; 4.3) for the same study arms; Anova p = 0.045]. Compared to P-RUTF, FSMS-RUTF had the highest adjusted recovery rate [OR (95%CI = 0.3 (0.2-0.5) with p < 0.001 for FSMS-RUTF and 0.6 (0.3-1.0) with p = 0.068 for MSMS-RUTF]. No effect of iron content on risk of iron overload or gut inflammation was observed. CONCLUSIONS: Anaemia and ID are common among children with SAM. FSMS-RUTF is more efficacious in treating anaemia and correcting BIS among this group than PM-RUTF. TRIAL REGISTRATION: This study was registered on 15 April 2015 ( PACTR201505001101224 ).

Relapse after severe acute malnutrition: A systematic literature review and secondary data analysis.

The objectives of most treatment programs for severe acute malnutrition (SAM) in children focus on initial recovery only, leaving post-discharge outcomes, such as relapse, poorly understood and undefined. This study aimed to systematically review current literature and conduct secondary data analyses of studies that captured relapse rates, up to 18-month post-discharge, in children following recovery from SAM treatment. The literature search (including PubMed and Google Scholar) built upon two recent reviews to identify a variety of up-to-date published studies and grey literature. This search yielded 26 articles and programme reports that provided information on relapse. The proportion of children who relapsed after SAM treatment varied greatly from 0% to 37% across varying lengths of time following discharge. The lack of a standard definition of relapse limited comparability even among the few studies that have quantified post-discharge relapse. Inconsistent treatment protocols and poor adherence to protocols likely add to the wide range of relapse reported. Secondary analysis of a database from Malawi found no significant association between potential individual risk factors at admission and discharge, except being an orphan, which resulted in five times greater odds of relapse at 6 months post-discharge (95% CI [1.7, 12.4], P = 0.003). The development of a standard definition of relapse is needed for programme implementers and researchers. This will allow for assessment of programme quality regarding sustained recovery and better understanding of the contribution of relapse to local and global burden of SAM.

Measuring growth and medium- and longer-term outcomes in malnourished children.

Severe and moderate acute malnutrition are among the leading causes of mortality among children in low- and middle-income countries. There is strong evidence that growth assessed anthropometrically from conception to 2 years of age marks later risk of ill health. This is central to the concept of the developmental origins of adult disease and is presumed to be related to modification of developmental processes during critical "window(s)" of vulnerability. Interventions to treat acute malnutrition have resulted in dramatic increase in the number of affected children surviving. Ensuring that these children thrive to fulfil their full physical and cognitive potential is a new challenge. Integral to this challenge is the need to be able to measure how earlier insults relate to the ability to survive and thrive to productive adulthood. Despite its obvious value, routine anthropometry does not adequately indicate how earlier adverse exposures affect more refined aspects of growth. Anthropometry is inadequate for predicting how disruption of healthy growth might modulate risk of disease or any subsequent interventions that correct this risk. A clear characterisation of healthy child growth is needed for determining which component best predicts later outcomes. The extent to which postnatal acute malnutrition is a consequence of maternal factors acting preconception or in utero and their relationship to postnatal health and long-term risk of non-communicable diseases is not clear. Body-composition measurement has significant untapped potential allowing us to translate and better understand the relationship between early insults and interventions on early growth in the short-term and long-term health outcomes.

Relapses from acute malnutrition and related factors in a community-based management programme in Burkina Faso.

Community-based management of acute malnutrition (CMAM) is effective in treating acute malnutrition. However, post-discharge follow-up often lacks. We aimed at assessing the relapse rate and the associated factors in a CMAM programme in Burkina Faso. Discharged children from the community nutrition centre were requested to return at least every 3 months for follow-up. The data of recovered children (weight-for-height z-score ≥-2) who were discharged between July 2010 and June 2011 were collected in 45 villages, randomly selected out of 210 in January 2012. Sociodemographic data, economic variables, information on household food availability and the child's food consumption in the last 24 h were collected from the parents. A multivariate Cox proportional hazards regression was used to identify the factors associated to relapse. Of the 637 children, 14 (2.2%) died and 218 (34.2%) were lost to follow-up. The relapse rate [95% confidence interval] among the children who returned for follow-up was 15.4 [11.8-19.0] per 100 children-years. The associated factors to relapses in multivariate Cox regression model were mid-upper arm circumference (MUAC) at discharge below 125 mm, no oil/fat consumption during the last 24 h and incomplete vaccination. To limit relapses, CMAM programmes should avoid premature discharge before a MUAC of at least 125 mm. Nutrition education should emphasize fat/oil as inexpensive energy source for children. Promoting immunization is essential to promote child growth. Periodic monitoring of discharged children should be organized to detect earlier those who are at risk of relapse. The relapse rate should be a CMAM effectiveness indicator.

Balancing omega-6 and omega-3 fatty acids in ready-to-use therapeutic foods (RUTF).

Ready-to-use therapeutic foods (RUTFs) are a key component of a life-saving treatment for young children who present with uncomplicated severe acute malnutrition in resource limited settings. Increasing recognition of the role of balanced dietary omega-6 and omega-3 polyunsaturated fatty acids (PUFA) in neurocognitive and immune development led two independent groups to evaluate RUTFs. Jones et al. (BMC Med 13:93, 2015), in a study in BMC Medicine, and Hsieh et al. (J Pediatr Gastroenterol Nutr 2015), in a study in the Journal of Pediatric Gastroenterology and Nutrition, reformulated RUTFs with altered PUFA content and looked at the effects on circulating omega-3 docosahexaenoic acid (DHA) status as a measure of overall omega-3 status. Supplemental oral administration of omega-3 DHA or reduction of RUTF omega-6 linoleic acid using high oleic peanuts improved DHA status, whereas increasing omega-3 alpha-linolenic acid in RUTF did not. The results of these two small studies are consistent with well-established effects in animal studies and highlight the need for basic and operational research to improve fat composition in support of omega-3-specific development in young children as RUTF use expands.

Ready-to-use therapeutic food with elevated n-3 polyunsaturated fatty acid content, with or without fish oil, to treat severe acute malnutrition: a randomized controlled trial.

BACKGROUND: Ready-to-use therapeutic foods (RUTF) are lipid-based pastes widely used in the treatment of acute malnutrition. Current specifications for RUTF permit a high n-6 polyunsaturated fatty acid (PUFA) content and low n-3 PUFA, with no stipulated requirements for preformed long-chain n-3 PUFA. The objective of this study was to develop an RUTF with elevated short-chain n-3 PUFA and measure its impact, with and without fish oil supplementation, on children's PUFA status during treatment of severe acute malnutrition. METHODS: This randomized controlled trial in children with severe acute malnutrition in rural Kenya included 60 children aged 6 to 50 months who were randomized to receive i) RUTF with standard composition; ii) RUTF with elevated short chain n-3 PUFA; or iii) RUTF with elevated short chain n-3 PUFA plus fish oil capsules. Participants were followed-up for 3 months. The primary outcome was erythrocyte PUFA composition. RESULTS: Erythrocyte docosahexaenoic acid (DHA) content declined from baseline in the two arms not receiving fish oil. Erythrocyte long-chain n-3 PUFA content following treatment was significantly higher for participants in the arm receiving fish oil than for those in the arms receiving RUTF with elevated short chain n-3 PUFA or standard RUTF alone: 3 months after enrollment, DHA content was 6.3% (interquartile range 6.0-7.3), 4.5% (3.9-4.9), and 3.9% (2.4-5.7) of total erythrocyte fatty acids (P <0.001), respectively, while eicosapentaenoic acid (EPA) content was 2.0% (1.5-2.6), 0.7% (0.6-0.8), and 0.4% (0.3-0.5) (P <0.001). RUTF with elevated short chain n-3 PUFA and fish oil capsules were acceptable to participants and carers, and there were no significant differences in safety outcomes. CONCLUSIONS: PUFA requirements of children with SAM are not met by current formulations of RUTF, or by an RUTF with elevated short-chain n-3 PUFA without additional preformed long-chain n-3 PUFA. Clinical and growth implications of revised formulations need to be addressed in large clinical trials. TRIAL REGISTRATION: Clinicaltrials.gov NCT01593969. Registered 4 May 2012.

Developing food supplements for moderately malnourished children: lessons learned from ready-to-use therapeutic foods.

Ready-to-use therapeutic foods (RUTFs) are solid foods that were developed by changing the formulation of the existing liquid diet, F-100, recommended by the World Health Organization (WHO) for the rapid catch-up phase of the treatment of children suffering from severe acute malnutrition (SAM). The resulting products proved highly effective in promoting weight gain in both severely and moderately wasted children and adults, including those infected with HIV. The formulation of the existing RUTFs, however, has never been optimized to maximize linear growth, vitamin and mineral status, and functional outcomes. The high milk content of RUTFs makes it an expensive product, and using lower quantities of milk seems desirable. However, the formulation of alternative, less expensive but more effective versions of RUTF faces difficult challenges, as there are uncertainties regarding the effect in terms of protein quality, antinutrient content, and flatulence factors that will result from the replacement of current dairy ingredients by less expensive protein-rich ingredients. The formulation of alternative RUTFs will require further research on these aspects, followed by efficacy studies comparing the future RUTFs to the existing formulations.

Ready-to-use foods for management of moderate acute malnutrition: considerations for scaling up production and use in programs.

Ready-to-use foods are one of the available strategies for the treatment of moderate acute malnutrition (MAM), but challenges remain in the use of these products in programs at scale. This paper focuses on two challenges: the need for cheaper formulations using locally available ingredients that are processed in a safe, reliable, and financially sustainable local production facility; and the effective use of these products in large-scale community-based programs. Linear programming tools can be used successfully to design local compositions that are in line with international guidelines, low in cost, and acceptable, and the efficacy of these local formulations in the treatment of MAM was recently demonstrated in Malawi. The production of local formulations for programs at scale relies on the existence of a reliable and efficient local production facility. Technical assistance may be required in the development of sustainable business models at an early stage in the process, taking into account the stringent product quality and safety criteria and the required investments. The use of ready-to-use products, as of any food supplement, in programs at scale will be affected by the practice of household sharing and diversion of these products for other uses. Additional measures can be considered to account for sharing. These products designed for the treatment and prevention of MAM are to be used in community-based programs and should therefore be used in conjunction with other interventions and designed so that they do not replace the intake of other foods and breastmilk. Remaining challenges and implications for the (operations) research agenda are discussed.

Comparison of the effectiveness of a milk-free soy-maize-sorghum-based ready-to-use therapeutic food to standard ready-to-use therapeutic food with 25% milk in nutrition management of severely acutely malnourished Zambian children: an equivalence non-blinded cluster randomised controlled trial.

Community-based Management of Acute Malnutrition using ready-to-use therapeutic food (RUTF) has revolutionised the treatment of severe acute malnutrition (SAM). However, 25% milk content in standard peanut-based RUTF (P-RUTF) makes it too expensive. The effectiveness of milk-free RUTF has not been reported hitherto. This non-blinded, parallel group, cluster randomised, controlled, equivalence trial that compares the effectiveness of a milk-free soy-maize-sorghum-based RUTF (SMS-RUTF) with P-RUTF in treatment of children with SAM, closes the gap. A statistician randomly assigned health centres (HC) either to the SMS-RUTF (n = 12; 824 enrolled) or P-RUTF (n = 12; 1103 enrolled) arms. All SAM children admitted at the participating HCs were enrolled. All the outcomes were measured at individual level. Recovery rate was the primary outcome. The recovery rates for SMS-RUTF and P-RUTF were 53.3% and 60.8% for the intention-to-treat (ITT) analysis and 77.9% and 81.8% for per protocol (PP) analyses, respectively. The corresponding adjusted risk difference (ARD) and 95% confidence interval, were -7.6% (-14.9, 0.6%) and -3.5% (-9,6., 2.7%) for ITT (P = 0.034) and PP analyses (P = 0.257), respectively. An unanticipated interaction (interaction P < 0.001 for ITT analyses and 0.0683 for PP analyses) between the study arm and age group was observed. The ARDs were -10.0 (-17.7 to -2.3)% for ITT (P = 0.013) and -4.7 (-10.0 to 0.7) for PP (P = 0.083) analyses for the <24 months age group and 2.1 (-10.3,14.6)% for ITT (P = 0.726) and -0.6 (-16.1, 14.5) for PP (P = 0.939) for the ≥24 months age group. In conclusion, the study did not confirm our hypothesis of equivalence between SMS-RUTF and P-RUTF in SAM management.

Severe acute malnutrition during emergencies: burden management, and gaps.

Natural and man-made disasters, including floods, droughts, earthquakes, and armed conflicts, create nutrition crises. Unfortunately, the frequency and severity of such disasters have been increasing since the beginning of the 20th century, and their contribution to the burden of acute malnutrition is increasing every year. However, their contribution to the burden of acute malnutrition is underrecognized due to the ways in which global statistics are built and causes of death are reported. Fortunately, the success of the current protocol for treatment of severe acute malnutrition (SAM) and the integrated approach to treatment has created a momentum allowing expanded coverage of treatment of SAM, especially in humanitarian emergency contexts. For this progress to be maintained and accelerated, changes in nutrition information systems at the national and global levels are needed, and the persisting barriers to the expansion and integration of treatment of SAM into routine health systems need to be removed. Emergency funding approaches and objectives have to include sustaining and amplifying the achievements of the short-term palliative interventions. Nutrition programs implemented in emergency contexts have the capacity to contribute to answering priority research questions, and this capacity should be more optimally utilized.

Effectiveness of milk whey protein-based ready-to-use therapeutic food in treatment of severe acute malnutrition in Malawian under-5 children: a randomised, double-blind, controlled non-inferiority clinical trial.

The cost of ready-to-use therapeutic food (RUTF) used in community-based management of acute malnutrition has been a major obstacle to the scale up of this important child survival strategy. The current standard recipe for RUTF [peanut-based RUTF (P-RUTF)] is made from peanut paste, milk powder, oil, sugar, and minerals and vitamins. Milk powder forms about 30% of the ingredients and may represent over half the cost of the final product. The quality of whey protein concentrates 34% (WPC34) is similar to that of dried skimmed milk (DSM) used in the standard recipe and can be 25-33% cheaper. This blinded, parallel group, randomised, controlled non-inferiority clinical trial tested the effectiveness in treating severe acute malnutrition (SAM) of a new RUTF formulation WPC-RUTF in which WPC34 was used to replace DSM. Average weight gain (non-inferiority margin Δ = -1.2 g kg(-1) day(-1) ) and recovery rate (Δ = -10%) were the primary outcomes, and length of stay (LOS) was the secondary outcome (Δ = +14 days). Both per-protocol (PP) and intention-to-treat (ITT) analyses showed that WPC-RUTF was not inferior to P-RUTF for recovery rate [difference and its 95% confidence interval (CI) of 0.5% (95% CI -2.7, 3.7) in PP analysis and 0.6% (95% CI -5.2, 6.3) in ITT analysis] for average weight gain [0.2 (-0.5; 0.9) for both analyses] and LOS [-1.6 days (95% CI, -4.6, 1.4 days) in PP analysis and -1.9 days (95% CI, -4.6, 0.8 days) for ITT analysis]. In conclusion, whey protein-based RUTF is an effective cheaper alternative to the standard milk-based RUTF for the treatment of SAM.

Sustainability and scaling-up analysis of community-based management of acute malnutrition: lessons learned from Burkina Faso.

BACKGROUND: Community-based management of acute malnutrition (CMAM) is an effective strategy frequently implemented by nongovernmental organizations, but handing CMAM over to national health systems and scaling it up remains a great challenge. OBJECTIVE: To highlight the challenges to sustainability and scalability of a CMAM program in Burkina Faso. METHODS: We conducted a review of program reports to evaluate program performance and conducted individual interviews with key informants (health system fieldworkers and officials and program staff members) and focus group discussions with beneficiaries (mothers whose children were attending the program, community volunteers, and village leaders) to analyze the required conditions for scaling up using ExpandNet recommendations. RESULTS: The program coverage rate was 90% among children under 5 years of age in the 180 intervention villages. Between June 2007 and December 2010, 19,009 cases of acute malnutrition (AM) among children under 5 years of age were treated, of which 4,308 (22.7%) were cases of severe acute malnutrition (SAM). The recovery rate was 89.4% for moderate acute malnutrition (MAM) and 86.5% for SAM. The case-fatality rate was 2.8% for MAM and 4.2% for SAM. The default rate was 7% for all cases. The prevalence of SAM decreased between 2008 and 2009 from 5.4% to 1.8%. Barriers to sustainability and scaling up were underlined: management by external personnel from the health system, no financial support for the scaling-up process, insufficient national advocacy, and nonsustainable activities (e.g., free care). CONCLUSIONS: The CMAM program was effective, but the handover conditions and scaling-up requirements were unsatisfactory. We identified poor integration into the health system, lack of resources, and insufficient advocacy.

Growth and Body Composition 5 y After Treatment for Severe Acute Malnutrition: A 5-y Prospective Matched Cohort Study in Ethiopian Children.

BACKGROUND: Short-term anthropometric outcomes are well documented for children treated for severe acute malnutrition (SAM). However, anthropometric recovery may not indicate restoration of healthy body composition. OBJECTIVES: This study aimed to evaluate long-term associations of SAM with growth and body composition of children 5 y after discharge from community-based management of acute malnutrition (CMAM). METHODS: We conducted a 5-y prospective cohort study, enrolling children aged 6 to 59 mo discharged from CMAM (post-SAM) (n = 203) and nonmalnourished matched controls (n = 202) from Jimma Zone, Ethiopia in 2013. Anthropometry and body composition (bioelectrical impedance) were assessed. Multiple linear regression models tested differences in height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ) z-scores; height-adjusted fat-free mass index (FFMI); and FM index (FMI) between groups. RESULTS: Post-SAM children had higher stunting prevalence than controls at discharge (82.2% compared with 36.0%; P < 0.001), 1 y (80.2% compared with 53.7%; P < 0.001), and 5 y postdischarge (74.2% compared with 40.8%; P < 0.001). Post-SAM children remained 5 cm shorter throughout follow-up, indicating no HAZ catch-up. No catch-up in WAZ or BAZ was observed. Post-SAM children had lower hip (-2.05 cm; 95% CI: -2.73, -1.36), waist (-0.92 cm; CI: -1.59, -0.23) and mid-upper arm (-0.64 cm; CI: -0.90, -0.42) circumferences and lower-limb length (-1.57 cm; 95% CI: -2.21, -0.94) at 5 y postdischarge. They had larger waist-hip (0.02 cm; 95% CI: 0.008, 0.033) and waist-height (0.013 cm; 95% CI: 0.004, 0.021) ratios, and persistent deficits in FFMI at discharge and 6 mo and 5 y postdischarge (P < 0.001 for all). No difference was detected in head circumference, sitting height, or FMI. CONCLUSIONS: Five y after SAM treatment, children maintained deficits in HAZ, WAZ, BAZ, and FFMI, with preservation of FMI, sitting height, and head circumference at the expense of lower-limb length, indicating a "thrifty growth" pattern. Research is urgently needed to identify effective clinical and public health interventions to mitigate these consequences of malnutrition.

A qualitative investigation of adherence to nutritional therapy in malnourished adult AIDS patients in Kenya.

OBJECTIVE: To understand factors affecting the compliance of malnourished, HIV-positive adults with a nutritional protocol using ready-to-use therapeutic food (RUTF; Plumpy'nut®). DESIGN: Qualitative study using key informant interviews, focus group discussions and direct observations. SETTING: Ministry of Health HIV/programme supported by Médecins Sans Frontièrs (MSF) in Nyanza Province, Kenya. SUBJECTS: Adult patients (n 46) currently or previously affected by HIV-associated wasting and receiving anti-retroviral therapy, their caregivers (n 2) and MoH/MSF medical employees (n 8). RESULTS: Thirty-four out of forty-six patients were receiving RUTF (8360 kJ/d) at the time of the study and nineteen of them were wasted (BMI < 17 kg/m2). Six of the thirteen wasted out-patients came to the clinic without a caregiver and were unable to carry their monthly provision (12 kg) of RUTF home because of physical frailty. Despite the patients' enthusiasm about their weight gain and rapid resumption of labour activities, the taste of the product, diet monotony and clinical conditions associated with HIV made it impossible for half of them to consume the daily prescription. Sharing the RUTF with other household members and mixing with other foods were common. Staff training did not include therapeutic dietetic counselling. CONCLUSIONS: The level of reported compliance with the prescribed dose of RUTF was low. An improved approach to treating malnourished HIV-positive adults in limited resource contexts is needed and must consider strategies to support patients without a caregiver, development of therapeutic foods more suited to adult taste, specific dietetic training for health staff and the provision of liquid therapeutic foods for severely ill patients.
