Home based therapy for severe malnutrition with ready-to-use food

Increasing Iron Intake of Children through Complementary Foods

Low intake of bioavailable iron from complementary foods is the major cause of the high prevalence of iron-deficiency anemia among children 6 to 24 months of age in developing countries. Increased dietary diversity and traditional food-processing techniques are generally unsuccessful at completely closing the gap between iron intake and needs. Thus, iron-fortified processed complementary foods or home fortification (using powders, crushable tablets, or fat-based products) will be needed in most populations. Several studies have demonstrated that both approaches are efficacious, though there are limited data on effectiveness on a wide scale. The choice of which product to promote may depend on the context, as well as cost constraints. No adverse effects of increasing iron intake through fortification or home fortification of complementary foods have been reported, but large-scale studies that include sufficient numbers of iron-replete children are lacking. Further research is needed to verify the safety of iron-fortification strategies, particularly in malarial areas.

Local Production and Provision of Ready-To-Use Therapeutic Food (Rutf) Spread for the Treatment of Severe Childhood Malnutrition

Background

Ready-to-use therapeutic food (RUTF) spread has been shown to be very effective in the rehabilitation of severely malnourished children and facilitates home-based therapy of these children.

Objective

To describe how RUTF spread can be manufactured on a variety of production scales.

Principles of production

RUTF spread is an edible lipid-based paste that is energy dense, resists bacterial contamination, and requires no cooking. The primary production principles include grinding all ingredients to a particle size < 200 microns, producing the food without the introduction of water, and embedding the protein and carbohydrate components of the food into the lipid matrix. The most widely used RUTF spread is a mixture of milk powder, sugar, vegetable oil, peanut butter, vitamins, and minerals.

Scale of production

RUTF spread can be produced in quantities sufficient to treat several hundred children using a planetary mixer in a clinic. Production of larger quantities of RUTF spread can be achieved in partnership with local food companies. Production sufficient to meet the needs of several thousand children can be achieved with a dedicated production facility using technology appropriate for use in the developing world. Care must be taken to avoid aflatoxin contamination, and quality control testing of the product is essential.

Conclusions

RUTF spread can be safely and easily produced in small or large quantities in most settings worldwide. The local availability of the necessary ingredients limits its use in some settings, and further investigation of alternative ingredients is needed to overcome this limitation.

Provision of lipid-based nutrient supplements to Honduran children increases their dietary macro- and micronutrient intake without displacing other foods

Inadequate energy intake and poor diet quality are important causes of chronic child undernutrition. Strategies for improving diet quality using lipid-based nutrient supplements (LNS) are currently being tested in several countries. To date, information on children's dietary intakes during LNS use is available only from Africa. In this study, we collected 24-h dietary recalls at baseline, 3, 6, 9 and 12 months on Honduran children (n = 298) participating in a cluster-randomised trial of LNS. Generalised estimating equations were used to examine differences in number of servings of 12 food groups in the LNS and control arms, and multi-level mixed effects models were used to compare macro- and micronutrient intakes. Models accounted for clustering and adjusted for child's age, season and breastfeeding status. Mean daily servings of 12 food groups did not differ by study arm at baseline and remained similar throughout the study with the exception of groups that were partially or entirely supplied by LNS (nuts and nut butters, fats, and sweets). Baseline intakes of energy, fat, carbohydrates, protein, folate and vitamin A, but not vitamin B12, iron and zinc were lower in the LNS than control arm. The change in all macro- and micronutrients from baseline to each study visit was larger for the LNS arm than the control, except for carbohydrates from baseline to 9 months. These findings indicate that LNS improved the macro- and micronutrient intakes of young non-malnourished Honduran children without replacing other foods in their diet.

Protein Quality and Growth in Malnourished Children

BACKGROUND

Protein quality refers to the amounts and ratios of essential amino acids in a food. Two methods most commonly used for determining protein quality are the protein digestibility-corrected amino acid score (PDCAAS) and the digestible indispensible amino acid score (DIAAS).

OBJECTIVE

To use existing literature to compare different amino acid profiles and PDCAAS and DIAAS scores in individuals with acute inflammation and to assess their relationship with weight gain in children with severe acute malnourished (SAM).

METHODS

A series stable isotope studies were previously conducted in children with SAM and acute infection, and these data were reviewed with respect to protein synthesis. Eleven published treatment trials for SAM with different therapeutic foods were analyzed to examine the relationship between protein quality scores with weight gain (g/kg/d). Protein scores were calculated with the PDCAAS and DIAAS amino acid reference patterns. A DIAAS score adjusted for the higher weight gain expected in malnourished children was also used. Bivariate correlation analysis was used to examine this relationship.

RESULTS

The protein kinetic data supported the hypothesis that a balance of amino acids that matches the composition of acute-phase proteins maximizes amino acid synthesis. Protein quality scores were highly correlated with the rate of weight gain in recovery from SAM, and the DIAAS scoring system adjusted for the higher expected weight gain had the strongest correlation with the observed weight gain.

CONCLUSION

Protein quality scores must account for physiologic status so that they better match with needs and thus better promote health.

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.

Peanut-based ready-to-use therapeutic food: acceptability among malnourished children and community workers in Bangladesh

OBJECTIVES

To assess the acceptability of a ready-to-use therapeutic food (Plumpy'nut(®) [PPN]) among 1) care givers of malnourished children and 2) community health workers (CHWs) at a nutrition rehabilitation centre in an urban slum in Dhaka, Bangladesh.

METHODS

This was a cross-sectional semi-structured questionnaire survey conducted between April and June 2011 as part of a nutritional programme run by Médecins Sans Frontières. The study population included care givers of malnourished children aged 6-59 months who received PPN for at least 3 weeks, and CHWs.

RESULTS

Of the 149 care givers (93% female) interviewed, 60% expressed problems with PPN acceptability. Overall, 43% perceived the child's dissatisfaction with the taste, 31% with consistency and 64% attributed side effects to PPN (nausea, vomiting, loose motion, diarrhoea, abdominal distension and pain). It is to be noted that 47% of children needed encouragement or were forced to eat PPN, while 5% completely rejected it after 3 weeks. Of the 29 CHWs interviewed, 48% were dissatisfied with PPN's taste and consistency, and 55% with its smell. However, 91% of the care givers and all CHWs still perceived a therapeutic benefit of PPN for malnourished children.

CONCLUSION

Despite a therapeutic benefit, only 4 in 10 care givers perceived PPN as being acceptable as a food product, which is of concern.

Comparison of Clinical Characteristics and Treatment Outcomes of Children Selected for Treatment of Severe Acute Malnutrition Using Mid Upper Arm Circumference and/or Weight-for-Height Z-Score

Objectives

Debate for a greater role of mid-upper arm circumference (MUAC) measures in nutritional programming continues, but a shift from therapeutic feeding programs admitting children using MUAC and/or weight-for-height Z (WHZ) to a new model admitting children using MUAC only remains complicated by limited information regarding the clinical profile and response to treatment of children selected by MUAC vs. WHZ. To broaden our understanding of how children identified for therapeutic feeding by MUAC and/or WHZ may differ, we aimed to investigate differences between children identified for therapeutic feeding by MUAC and/or WHZ in terms of demographic, anthropometric, clinical, and laboratory and treatment response characteristics.

Methods

Using secondary data from a randomized trial in rural Niger among children with uncomplicated severe acute malnutrition, we compared children that would be admitted to a therapeutic feeding program that used a single anthropometric criterion of MUAC< 115 mm vs. children that are admitted under current admission criteria (WHZ< -3 and/or MUAC< 115 mm) but would be excluded from a program that used a single MUAC< 115 mm admission criterion. We assessed differences between groups using multivariate regression, employing linear regression for continuous outcomes and log-binomial regression for dichotomous outcomes.

Results

We found no difference in terms of clinical and laboratory characteristics and discharge outcomes evaluated between children that would be included in a MUAC< 115 mm therapeutic feeding program vs. children that are currently eligible for therapeutic feeding but would be excluded from a MUAC-only program.

Conclusions

A single anthropometric admission criterion of MUAC < 115 mm did not differentiate well between children in terms of clinical or laboratory measures or program outcomes in this context. If nutritional programming is to use a single MUAC-based criterion for admission to treatment, further research and program experience can help to identify the most appropriate criterion in a broad range of contexts to target children in most urgent need of treatment.

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.

High-Oleic Ready-to-Use Therapeutic Food Maintains Docosahexaenoic Acid Status in Severe Malnutrition

OBJECTIVES

Ready-to-use therapeutic food (RUTF) is the preferred treatment for uncomplicated severe acute malnutrition. It contains large amounts of linoleic acid and little α-linolenic acid, which may reduce the availability of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) to the recovering child. A novel high-oleic RUTF (HO-RUTF) was developed with less linoleic acid to determine its effect on DHA and EPA status.

METHODS

We conducted a prospective, randomized, double-blind clinical effectiveness trial treating rural Malawian children with severe acute malnutrition. Children were treated with either HO-RUTF or standard RUTF. Plasma phospholipid fatty acid status was measured on enrollment and after 4 weeks and compared between the 2 intervention groups.

RESULTS

Among the 141 children enrolled, 48 of 71 receiving HO-RUTF and 50 of 70 receiving RUTF recovered. Plasma phospholipid samples were analyzed from 43 children consuming HO-RUTF and 35 children consuming RUTF. The change in DHA content during the first 4 weeks was +4% and -25% in the HO-RUTF and RUTF groups, respectively (P = 0.04). For EPA, the change in content was 63% and -24% in the HO-RUTF and RUTF groups, respectively (P < 0.001). For arachidonic acid, the change in content was -3% and 13% in the HO-RUTF and RUTF groups, respectively (P < 0.009).

CONCLUSIONS

The changes in DHA and EPA seen in the children treated with HO-RUTF warrant further investigation because they suggest that HO-RUTF support improved polyunsaturated fatty acid status, necessary for neural development and recovery.

Anorexia nervosa, seasonality, and polyunsaturated fatty acids

Anorexia nervosa is a serious neurobehavioral disorder marked by semistarvation, extreme fear of weight gain, frequently hyperactivity, and low body temperature. The etiology remains unknown. We present a speculation that a primary causative factor is that polyunsaturated fatty acids are skewed to prevent oxidative damage in phospholipid membranes. This causes a change in the trade off of oxidation protection vs homeoviscous adaptation to lower temperatures, which sets off a metabolic cascade that leads to the rogue state of anorexia nervosa.

Diagnosis and treatment of severely malnourished children with diarrhoea

Children with severe acute malnutrition complicated by diarrhoea require special care due to their unique physiological vulnerability and increased mortality risks. A systematic literature review (1950-2013) was conducted to identify the most effective diagnostic and therapeutic measures for the community-based management of severely malnourished children with diarrhoea. No studies directly addressed this question, so the search was broadened to include inpatient care. Of the 129 studies identified, 32 were selected for full review and found to contain varying degrees of indirectness, inconsistency and bias. Evidence from diagnostic studies point to the use of both prolonged and persistent diarrhoea as morbidity markers, rapid hypoglycaemia diagnosis and the frequent aetiological role of Cryptosporidium. Therapeutic studies suggest benefits from routine antiparasitic medication and feeding regimens with ready-to-use-therapeutic foods, lactose-free diets and zinc supplementation. Existing rehydration treatment guidelines were affirmed, but the utility of glutamine and low osmolarity feeds were inconclusive.

Comparison of weight-for-height and mid-upper arm circumference (MUAC) in a therapeutic feeding programme in South Sudan: is MUAC alone a sufficient criterion for admission of children at high risk of mortality?

OBJECTIVE

The present study was performed to describe the operational implications of using mid-upper arm circumference (MUAC) as a single admission criterion for treatment of severe acute malnutrition in South Sudan.

DESIGN

We performed a retrospective analysis of routine programme data of children with severe acute malnutrition aged 6-59 months admitted to a therapeutic feeding programme using weight-for-height Z-score (WHZ) and/or MUAC. To understand the implications of using MUAC as a single admission criterion, we compared patient characteristics and treatment outcomes for children admitted with MUAC<115 mm (irrespective of WHZ) v. children admitted with WHZ<-3 and MUAC≥115 mm.

RESULTS

Of 2205 children included for analysis, 719 (32·6 %) were admitted to the programme with MUAC<115 mm and 1486 (67·4 %) with WHZ<-3 and MUAC≥115 mm. Children who would have been admitted using a single MUAC<115 mm criterion were more severely malnourished and more likely to be female and younger. Compared with children admitted with WHZ<-3 and MUAC≥115 mm, children who would have been admitted using MUAC<115 mm were less likely to recover (54 % v. 69 %) and had higher risk of death (4 % v. 1 %), but responded to treatment with greater weight and MUAC gains. MUAC<115 mm would have failed to identify 33 % of deaths, while 98 % were identified by WHZ<-3 alone and 100 % by MUAC<130 mm.

CONCLUSIONS

The study shows that MUAC<115 mm identified more severely malnourished children with a higher risk of mortality but failed to identify a third of the children who died. Admission criteria for therapeutic feeding should be adapted to the programmatic context with consideration for both operational and public health implications.

Perceptions of usage and unintended consequences of provision of ready-to-use therapeutic food for management of severe acute child malnutrition. A qualitative study in Southern Ethiopia

Background: Severe acute child malnutrition (SAM) is associated with high risk of mortality. To increase programme effectiveness in management of SAM, community-based management of acute malnutrition (CMAM) programme that treats SAM using ready-to-use-therapeutic foods (RUTF) has been scaled-up and integrated into existing government health systems. The study aimed to examine caregivers’ and health workers perceptions of usages of RUTF in a chronically food insecure area in South Ethiopia.

Methods: This qualitative study recorded, transcribed and translated focus group discussions and individual interviews with caregivers of SAM children and community health workers (CHWs). Data were complemented with field notes before qualitative content analysis was applied.

Results: RUTF was perceived and used as an effective treatment of SAM; however, caregivers also see it as food to be shared and when necessary a commodity to be sold for collective benefits for the household. Caregivers expected prolonged provision of RUTF to contribute to household resources, while the programme guidelines prescribed RUTF as a short-term treatment to an acute condition in a child. To get prolonged access to RUTF caregivers altered the identities of SAM children and sought multiple admissions to CMAM programme at different health posts that lead to various control measures by the CHWs.

Conclusion: Even though health workers provide RUTF as a treatment for SAM children, their caregivers use it also for meeting broader food and economic needs of the household endangering the effectiveness of CMAM programme. In chronically food insecure contexts, interventions that also address economic and food needs of entire household are essential to ensure successful treatment of SAM children. This may need a shift to view SAM as a symptom of broader problems affecting a family rather than a disease in an individual child.

Malian children with moderate acute malnutrition who are treated with lipid-based dietary supplements have greater weight gains and recovery rates than those treated with locally produced cereal-legume products: a community-based, cluster-randomized trial

BACKGROUND

Moderate acute malnutrition (MAM), defined as weight-for-length z score between -3 and -2 or midupper arm circumference between 11.5 and 12.5 cm, affects ∼33 million children aged <5 y worldwide.

OBJECTIVE

The objective was to compare the effects of 4 dietary supplements for the treatment of MAM.

DESIGN

Twelve community health centers in rural Mali were randomly assigned to provide to 1264 MAM children aged 6-35 mo one of 4 dietary supplements containing ∼500 kcal/d for 12 wk: 1) ready-to-use, lipid-based supplementary food (RUSF); 2) special corn-soy blend (CSB++); 3) locally processed, fortified flour (Misola); or 4) locally milled flours plus oil, sugar, and micronutrient powder (LMF).

RESULTS

In total, 1178 children (93.2%) completed the study. The adjusted mean (95% CI) change in weight (kg) from baseline was greater with RUSF than with the locally processed blends and was intermediate with CSB++ [1.16 (1.08, 1.24) for RUSF, 1.04 (0.96, 1.13) for CSB++, 0.91 (0.82, 0.99) for Misola, and 0.83 (0.74, 0.92) for LMF; P < 0.001]. For length change, RUSF and CSB++ differed significantly from LMF. Sustained recovery rates were higher with RUSF (73%) than with Misola (61%) and LMF (58%), P < 0.0001; CSB++ recovery rates (68%) did not differ from any of the other groups.

CONCLUSIONS

RUSF was more effective, but more costly, than other dietary supplements for the treatment of MAM; CSB++ yielded intermediate results. The benefits of treatment should be considered in relation to product costs and availability.

Late presentation to hospital services necessitates greater community-based care for malnourished children

The records for all paediatric deaths (ages 0-14) in a large hospital in urban Southern Africa were examined for a 3 year period (January 2007 to February 2010), to explore the role of malnutrition in paediatric mortality in this region. A total of 516 records were obtained, demonstrating that malnutrition was the primary or secondary cause of death in 35% of cases. It was also found that children presented very late to hospital services, with an average length of final admission of only 0-3 days. The rate of human immunodeficiency virus (HIV) infection was found to be very high, although low testing rates limits the analysis of these figures. Malnutrition remains an important factor in paediatric mortality in southern Africa, contributing to approximately 35% of deaths. Furthermore, fatal cases presented very late to hospital services. In light of this, increased community-based therapy would be beneficial. Implementation of universal HIV testing would also be valuable.

Home-based therapy for severe acute malnutrition with ready-to-use food

Severe acute malnutrition is a devastating condition afflicting under-5 children in many developing countries, but concentrated in sub-Saharan Africa. This paper examines the development of home-based lipid-nutrient therapeutic foods for the treatment of acute malnutrition in sub-Saharan Africa and the adoption of these therapies as a standard of care for non-complicated cases of acute malnutrition. Several of the early key clinical and operational effectiveness trials are discussed as well as the adoption of home-based treatment as a standard operating procedure in regions where malnutrition is present.

Community-based management of acute malnutrition in Bangladesh: feasibility and constraints

BACKGROUND

To achieve the United Nations Millennium Development Goals, particularly reduction in child mortality (Millennium Development Goal 4), effective interventions to address severe and moderate acute malnutrition (SAM and MAM) among children under 5 years of age must be implemented and brought to scale alongside preventive measures. Bangladesh has an estimated 600,000 children with SAM, for a prevalence of 4%, while 1.8 million children suffer from MAM.

OBJECTIVE

To assess the feasibility and constraints of community-based management of acute malnutrition (CMAM), a relatively new approach, in managing SAM and MAM among children in Bangladesh.

METHODS

The methodology involved desk reviews of documents by searching through PubMed and other databases for published literature on CMAM in Bangladesh. We also did a hand search of policy and program documents, including the draft National Nutrition Policy 2013; the Health, Nutrition, Population Sector Development Program document of the Ministry of Health and Family Welfare, Government of Bangladesh; the Sixth Five Year Plan; and the Operational Plans of the National Nutrition Services of Bangladesh.

RESULTS

. The conventional approach in Bangladesh has been to treat children suffering from SAM and associated complications in hospital settings. There is no program to take care of children with MAM. There is a dearth of local evidence to operationalize and implement CMAM in the context of Bangladesh. This paper summarizes the scientific literature and rationale for the implementation of CMAM in Bangladesh. It also provides recommendations to improve health strategies related to CMAM, discusses diets being developed that may result in better implementation of CMAM, and offers recommendations for areas of additional necessary research.

CONCLUSIONS

A recommended approach for Bangladesh on the management of acute malnutrition would be to integrate CMAM into the rollout of the National Nutrition Services so that screening, identification, referral, and treatment of acutely malnourished children could be effectively managed within the community-based health service delivery system. Given that the vast majority of children are suffering from MAM and could be treated with locally developed food supplements, a significant emphasis of the CMAM approach in Bangladesh should be to screen and treat MAM. Over time, this would also result in fewer SAM cases. However, even with this approach, there would still be a small number of children who have SAM and who ideally should be treated with specialized therapeutic foods. While the Government of Bangladesh is awaiting full-scale production of a local ready-to-use therapeutic food (RUTF), an interim strategy is needed to effectively treat these severely wasted children on an outpatient basis.

Effect of 12-month intervention with lipid-based nutrient supplements on physical activity of 18-month-old Malawian children: a randomised, controlled trial

BACKGROUND/OBJECTIVES

This study measured the effects of dietary supplementation with lipid-based nutrient supplements (LNSs) on 18-month-old children's physical activity.

SUBJECTS/METHODS

In a randomised, controlled, outcome-assessor blinded trial 1932 six-month-old children from Malawi received one of five interventions daily from 6-18 months of age: 10-g milk-LNS, 20-g milk-LNS, 20-g non-milk-LNS, 40-g milk-LNS or 40-g non-milk-LNS, or received no intervention in the same period (control). The control group received delayed intervention with corn-soy blend from 18-30 months. Physical activity was measured over 1 week by ActiGraph GT3X+ accelerometer at 18 months. Main outcome was mean vector magnitude accelerometer counts/15 s. Analyses were restricted to children with valid accelerometer data on at least 4 days with minimum 6 h of wearing time per day.

RESULTS

Of the 1435 children recruited to this substudy, 1053 provided sufficient data for analysis. The mean (s.d.) vector magnitude accelerometer counts in the total sample were 307 (64). The difference (95% CI) in mean accelerometer counts, compared with the control group, was 8 (-6 to 21, P=0.258) in 10-g milk-LNS, 3 (-11 to 17, P=0.715) in 20-g milk-LNS, 5 (-8 to 19, P=0.445) in 20-g non-milk-LNS, 10 (-3 to 23, P=0.148) in 40-g milk-LNS and 2 (-12 to 16, P=0.760) in 40-g non-milk-LNS groups.

CONCLUSIONS

Provision of 10-40 g doses of LNS daily for 12 months did not increase physical activity of Malawian toddlers.

Effect of supplementation with a lipid-based nutrient supplement on the micronutrient status of children aged 6-18 months living in the rural region of Intibucá, Honduras

BACKGROUND

Lipid-based nutrient supplements (LNS) have been effective in the treatment of acute malnutrition among children. We evaluated the use of LNS supplementation for improving the micronutrient status of young children.

METHODS

A 12-month randomised controlled trial was conducted among children aged 6-18 months living in Intibucá, Honduras. Communities (n = 18) were randomised into clusters matched by poverty indicators (9 intervention, n = 160 and 9 controls, n = 140). Intervention participants received LNS. All children received food vouchers and nutrition education. Primary outcomes included measures of micronutrient status: at baseline, 6 and 12 months' blood were collected for assessment of folate, iron, zinc, riboflavin, and vitamin B12 status; haemoglobin was measured every 3 months; and dietary and anthropometry collected monthly. Longitudinal analyses were based on intent to treat and LNS adherence. Generalised estimating equations were used in the estimation of generalised linear regression models specified for the data.

RESULTS

At 6-month follow-up, children in the intervention group had a lower proportion classified as deficient for B12 (43.6%) compared with the control (67.7%; P = 0.03). The intervention group had a higher mean concentration for folate at 6 months (P = 0.06), and improvements continued through 12 months for folate (P = 0.002) and vitamin A deficiency (P = 0.03). This pattern of results, with improved significance, remained in subanalysis based on LNS adherence.

CONCLUSION

These data demonstrate that LNS improved select micronutrient status in young non-malnourished Honduran children.

Equity in access to fortified maize flour and corn meal

Mass fortification of maize flour and corn meal with a single or multiple micronutrients is a public health intervention that aims to improve vitamin and mineral intake, micronutrient nutritional status, health, and development of the general population. Micronutrient malnutrition is unevenly distributed among population groups and is importantly determined by social factors, such as living conditions, socioeconomic position, gender, cultural norms, health systems, and the socioeconomic and political context in which people access food. Efforts trying to make fortified foods accessible to the population groups that most need them require acknowledgment of the role of these determinants. Using a perspective of social determinants of health, this article presents a conceptual framework to approach equity in access to fortified maize flour and corn meal, and provides nonexhaustive examples that illustrate the different levels included in the framework. Key monitoring areas and issues to consider in order to expand and guarantee a more equitable access to maize flour and corn meal are described.

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.

Protecting child health and nutrition status with ready-to-use food in addition to food assistance in urban Chad: a cost-effectiveness analysis

Background

Despite growing interest in use of lipid nutrient supplements for preventing child malnutrition and morbidity, there is inconclusive evidence on the effectiveness, and no evidence on the cost-effectiveness of this strategy.

Methods

A cost effectiveness analysis was conducted comparing costs and outcomes of two arms of a cluster randomized controlled trial implemented in eastern Chad during the 2010 hunger gap by Action contre la Faim France and Ghent University. This trial assessed the effect on child malnutrition and morbidity of a 5-month general distribution of staple rations, or staple rations plus a ready-to-use supplementary food (RUSF). RUSF was distributed to households with a child aged 6–36 months who was not acutely malnourished (weight-for-height > = 80% of the NCHS reference median, and absence of bilateral pitting edema), to prevent acute malnutrition in these children. While the addition of RUSF to a staple ration did not result in significant reduction in wasting rates, cost-effectiveness was assessed using successful secondary outcomes of cases of diarrhea and anemia (hemoglobin <110 g/L) averted among children receiving RUSF.

Total costs of the program and incremental costs of RUSF and related management and logistics were estimated using accounting records and key informant interviews, and include costs to institutions and communities. An activity-based costing methodology was applied and incremental costs were calculated per episode of diarrhea and case of anemia averted.

Results

Adding RUSF to a general food distribution increased total costs by 23%, resulting in an additional cost per child of 374 EUR, and an incremental cost per episode of diarrhea averted of 1,083 EUR and per case of anemia averted of 3,627 EUR.

Conclusions

Adding RUSF to a staple ration was less cost-effective than other standard intervention options for averting diarrhea and anemia. This strategy holds potential to address a broad array of health and nutrition outcomes in emergency settings where infrastructure is weak and other intervention options are infeasible in the short-term. However, further research is needed to establish the contexts in which RUSF is most effective and cost-effective in preventing acute malnutrition and morbidity among vulnerable children, compared to other options.

Effectiveness of indigenous ready-to-use therapeutic food in community-based management of uncomplicated severe acute malnutrition: a randomized controlled trial from India

A randomized controlled trial was conducted in Chandigarh, India (2011), to determine the effectiveness of indigenous ready-to-use therapeutic food (RUTF) in community-based management of uncomplicated severe acute malnutrition (SAM). Intervention was through outpatient therapeutic program site (OTP). Study and control group children (6 months-5 years) were followed up weekly for 12 weeks, in OTP and at home. All children received supplementary nutrition through anganwadis under integrated child development scheme. Study children, in addition, received therapeutic dose of RUTF in OTP. Primary outcome, 115% of baseline weight, was attained in 6 of 13 (46.2%) and 1 of 13 (7.7%) children among study and control group, respectively [odds ratio: 10.28, 95% confidence interval (CI): 1.02-103.95]. Compared with control group, addition of RUTF in study group resulted in average additional increase in weight by 13 g/kg of baseline weight/week/child (95% CI: 2-23). Indigenous RUTF was effective in community-based management of uncomplicated SAM.

Treatment of severe and moderate acute malnutrition in low- and middle-income settings: a systematic review, meta-analysis and Delphi process

BACKGROUND

Globally, moderate acute malnutrition (MAM) and severe acute malnutrition (SAM) affect approximately 52 million children under five. This systematic review evaluates the effectiveness of interventions for SAM including the World Health Organization (WHO) protocol for inpatient management and community-based management with ready-to-use-therapeutic food (RUTF), as well as interventions for MAM in children under five years in low- and middle-income countries.

METHODS

We systematically searched the literature and included 14 studies in the meta-analysis. Study quality was assessed using CHERG adaptation of GRADE criteria. A Delphi process was undertaken to complement the systematic review in estimating case fatality and recovery rates that were necessary for modelling in the Lives Saved Tool (LiST).

RESULTS

Case fatality rates for inpatient treatment of SAM using the WHO protocol ranged from 3.4% to 35%. For community-based treatment of SAM, children given RUTF were 51% more likely to achieve nutritional recovery than the standard care group. For the treatment of MAM, children in the RUSF group were significantly more likely to recover and less likely to be non-responders than in the CSB group. In both meta-analyses, weight gain in the intervention group was higher, and although statistically significant, these differences were small. Overall limitations in our analysis include considerable heterogeneity in many outcomes and an inability to evaluate intervention effects separate from commodity effect. The Delphi process indicated that adherence to standardized protocols for the treatment of SAM and MAM should have a marked positive impact on mortality and recovery rates; yet, true consensus was not achieved.

CONCLUSIONS

Gaps in our ability to estimate effectiveness of overall treatment approaches for SAM and MAM persist. In addition to further impact studies conducted in a wider range of settings, more high quality program evaluations need to be conducted and the results disseminated.

Iron bioavailability from a lipid-based complementary food fortificant mixed with millet porridge can be optimized by adding phytase and ascorbic acid but not by using a mixture of ferrous sulfate and sodium iron EDTA

Home fortification with lipid-based nutrient supplements (LNSs) is a promising approach to improve bioavailable iron and energy intake of young children in developing countries. To optimize iron bioavailability from an LNS named complementary food fortificant (CFF), 3 stable isotope studies were conducted in 52 young Beninese children. Test meals consisted of millet porridge mixed with CFF and ascorbic acid (AA). Study 1 compared iron absorption from FeSO4-fortifed meals with meals fortified with a mixture of FeSO4 and NaFeEDTA. Study 2 compared iron absorption from FeSO4-fortifed meals without or with extra AA. Study 3 compared iron absorption from FeSO4-fortified meals with meals containing phytase added prior to consumption, once without or once with extra AA. Iron absorption was measured as erythrocyte incorporation of stable isotopes. In study 1, iron absorption from FeSO4 (8.4%) was higher than that from the mixture of NaFeEDTA and FeSO4 (5.9%; P < 0.05). In study 2, the extra AA increased absorption (11.6%) compared with the standard AA concentration (7.3%; P < 0.001). In study 3, absorption from meals containing phytase without or with extra AA (15.8 and 19.9%, respectively) increased compared with meals without phytase (8.0%; P < 0.001). The addition of extra AA to meals containing phytase increased absorption compared with the test meals containing phytase without extra AA (P < 0.05). These findings suggest that phytase and AA, and especially a combination of the two, but not a mixture of FeSO4 and NaFeEDTA would be useful strategies to increase iron bioavailability from a CFF mixed with cereal porridge.

Responsive feeding and child interest in food vary when rural Malawian children are fed lipid-based nutrient supplements or local complementary food

Caregiver and child behaviours during feeding have been used to measure responsiveness, which has been recognised as important for child growth and development. The aims of this study were to understand how caregiver and child behaviours differ when feeding lipid-based nutrient supplements (LNS) vs. local complementary food and to detect associations between behaviours and child interest in food. Sixteen moderately underweight 6-17-month-old Malawian children receiving 50 g/day of supplementary LNS for 12 weeks were videotaped during LNS (n = 32) and local complementary feeding (n = 28) episodes. Behaviours were coded at the level of the intended bite (1674 total bites). The analysis used regression models adjusted for within-subject correlation. Caregivers were less likely to allow children to self-feed and more likely to use physical pressure during LNS vs. complementary food bites. Positive caregiver verbalization was infrequent and did not differ by type of food. Higher odds of accepting a bite were associated with the bite containing LNS, odds ratio (OR) 3.05; 90% confidence interval (CI) (1.98, 4.71), the child self-feeding, OR 5.70; 90% CI (2.77, 11.69), and positive caregiver verbalization, OR 2.46; 90% CI (1.26, 4.80), while lower odds of acceptance were associated with negative child verbalization during feeding, OR 0.27; 90% CI (0.17, 0.42). In this sample, caregivers used more responsive feeding practices during bites of local complementary food and were more controlling when feeding LNS. Responsive caregiver behaviours predicted child acceptance of food. These results could be used to design interventions in Malawi to improve responsive feeding practices in general and during LNS use.

Specially formulated foods for treating children with moderate acute malnutrition in low- and middle-income countries

BACKGROUND

Moderate acute malnutrition, also called moderate wasting, affects around 10% of children under five years of age in low- and middle-income countries. There are different approaches to addressing malnutrition with prepared foods in these settings; for example, providing lipid-based nutrient supplements or blended foods, either a full daily dose or in a low dose as a complement to the usual diet. There is no definitive consensus on the most effective way to treat children with moderate acute malnutrition.

OBJECTIVES

To evaluate the safety and effectiveness of different types of specially formulated foods for children with moderate acute malnutrition in low- and middle-income countries, and to assess whether foods complying or not complying with specific nutritional compositions, such as the WHO technical specifications, are safe and effective.

SEARCH METHODS

In October 2012, we searched CENTRAL, MEDLINE, LILACS, CINAHL, BIBLIOMAP, POPLINE, ZETOC, ICTRP, mRCT, and ClinicalTrials.gov. In August 2012, we searched Embase. We also searched the reference lists of relevant papers and contacted nutrition-related organisations and researchers in this field.    

SELECTION CRITERIA

We planned to included any relevant randomised controlled trials (RCTs), controlled clinical trials (CCTs), controlled before-and-after studies (CBAs), and interrupted time series (ITS) that evaluated specially formulated foods for the treatment of moderate acute malnutrition in children aged between six months and five years in low- and middle-income countries.

DATA COLLECTION AND ANALYSIS

Two authors assessed trial eligibility and risk of bias, and extracted and analysed the data. We summarised dichotomous outcomes using risk ratios (RR) and continuous outcomes using mean differences (MD) with 95% confidence intervals (CI). Where appropriate, we combined data in meta-analyses using the random-effects model and assessed heterogeneity. The quality of evidence was assessed using GRADE methods.

MAIN RESULTS

Eight randomised controlled trials, enrolling 10,037 children, met our inclusion criteria. Seven of the trials were conducted in Africa. In general, the included studies were at a low risk of bias. There may have been a risk of performance bias as trial participants were aware which intervention group they were in, but we did not consider this likely to have biased the outcome measurement. We were unable to assess the risk of reporting bias in half of the trials and two trials were at high risk of attrition bias. Any specially formulated food versus standard care - the provision of food increased the recovery rate by 29% (RR 1.29, 95% CI 1.20 to 1.38; 2152 children, two trials; moderate quality evidence), decreased the number dropping out by 70% (RR 0.30, 95% CI 0.22 to 0.39; 1974 children, one trial; moderate quality evidence), and improved weight-for-height (MD 0.20 z-score, 95% CI 0.03 to 0.37; 1546 children, two trials; moderate quality evidence). The reduction in mortality did not reach statistical significance (RR 0.44; 95% CI 0.14 to 1.36; 1974 children, one trial; low quality evidence). Lipid-based nutrient supplements versus any blended foods (dry food mixtures, without high lipid content), at full doses - there was no significant difference in mortality (RR 0.93, 95% CI 0.54 to 1.62; 6367 children, five trials; moderate quality evidence), progression to severe malnutrition (RR 0.88, 95% CI 0.72 to 1.07; 4537 children, three trials; high quality evidence), or the number of dropouts from the nutritional programme (RR 1.14, 95% CI 0.62 to 2.11; 5107 children, four trials; moderate quality evidence). However, lipid-based nutrient supplements significantly increased the number of children recovered (RR 1.10, 95% CI 1.04 to 1.16; 6367 children, five trials; moderate quality evidence), and decreased the number of non-recovering children (RR 0.53, 95% CI 0.40 to 0.69; 4537 children, three trials; high quality evidence). LNS also improved weight gain, weight-for-height, and mid-upper arm circumference, although for these outcomes, the improvement was modest (moderate quality evidence). One trial observed more children with vomiting in the lipid-based nutrient supplements group compared to those receiving blended food (RR 1.43, 95% CI 1.11 to 1.85; 2712 children, one trial; low quality evidence). Foods at complementary doses - no firm conclusion could be drawn on the comparisons between LNS at complementary dose and blended foods at complementary or full dose (low quality evidence). Lipid-based nutrient supplements versus specific types of blended foods - a recently developed enriched blended food (CSB++) resulted in similar outcomes to LNS (4758 children, three trials; moderate to high quality evidence). Different types of blended foods - in one trial, CSB++ did not show any significant benefit over locally made blended food, for example, Misola, in number who recovered, number who died, or weight gain (moderate to high quality evidence). Improved adequacy of home diet - no study evaluated the impact of improving adequacy of local diet, such as local foods prepared at home according to a given recipe or of home processing of local foods (soaking, germination, malting, fermentation) in order to increase their nutritional content.

AUTHORS' CONCLUSIONS

In conclusion, there is moderate to high quality evidence that both lipid-based nutrient supplements and blended foods are effective in treating children with MAM. Although lipid-based nutrient supplements (LNS) led to a clinically significant benefit in the number of children recovered in comparison with blended foods, LNS did not reduce mortality, the risk of default or progression to SAM. It also induced more vomiting. Blended foods such as CSB++ may be equally effective and cheaper than LNS. Most of the research so far has focused on industrialised foods, and on short-term outcomes of MAM. There are no studies evaluating interventions to improve the quality of the home diet, an approach that should be evaluated in settings where food is available, and nutritional education and habits are the main determinants of malnutrition. There are no studies from Asia, where moderate acute malnutrition is most prevalent.

Ready-to-use therapeutic food for home-based treatment of severe acute malnutrition in children from six months to five years of age

BACKGROUND

Malnourished children have a higher risk of death and illness. Treating severe acute malnourished children in hospitals is not always desirable or practical in rural settings, and home treatment may be better. Home treatment can be food prepared by the carer, such as flour porridge, or commercially manufactured food such as ready-to-use therapeutic food (RUTF). RUTF is made according to a standard, energy-rich composition defined by the World Health Organization (WHO). The benefits of RUTF include a low moisture content, long shelf life without needing refrigeration and that it requires no preparation.

OBJECTIVES

To assess the effects of home-based RUTF on recovery, relapse and mortality in children with severe acute malnutrition.

SEARCH METHODS

We searched the following electronic databases up to April 2013: Cochrane Central Register of Clinical Trials (CENTRAL), MEDLINE, MEDLINE In-process, EMBASE, CINAHL, Science Citation Index, African Index Medicus, LILACS, ZETOC and three trials registers. We also contacted researchers and clinicians in the field and handsearched bibliographies of included studies and relevant reviews.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials where children between six months and five years of age with severe acute malnutrition were treated at home with RUTF compared to a standard diet, or different regimens and formulations of RUTFs compared to each other. We assessed recovery, relapse and mortality as primary outcomes, and anthropometrical changes, time to recovery and adverse outcomes as secondary outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial eligibility using prespecified criteria, and three review authors independently extracted data and assessed trial risk of bias.

MAIN RESULTS

We included four trials (three having a high risk of bias), all conducted in Malawi with the same contact author. One small trial included children infected with human immunodeficiency virus (HIV). We found the risk of bias to be high for the three quasi-randomised trials while the fourth trial had a low to moderate risk of bias. Because of the sparse data for HIV, we reported below the main results for all children together. RUTF meeting total daily requirements versus standard dietWhen comparing RUTF with standard diet (flour porridge), we found three quasi-randomised cluster trials (n = 599). RUTF may improve recovery slightly (risk ratio (RR) 1.32; 95% confidence interval (CI) 1.16 to 1.50; low quality evidence), but we do not know whether RUTF improves relapse, mortality or weight gain (very low quality evidence). RUTF supplement versus RUTF meeting total daily requirementsWhen comparing RUTF supplement with RUTF that meets total daily nutritional requirements, we found two quasi-randomised cluster trials (n = 210). For recovery, relapse, mortality and weight gain the quality of evidence was very low; therefore, the effects of RUTF are unknown. RUTF containing less milk powder versus standard RUTFWhen comparing a cheaper RUTF containing less milk powder (10%) versus standard RUTF (25% milk powder), we found one trial that randomised 1874 children. For recovery, there was probably little or no difference between the groups (RR 0.97; 95% CI 0.93 to 1.01; moderate quality evidence). RUTF containing less milk powder may lead to slightly more children relapsing (RR 1.33; 95% CI 1.03 to 1.72; low quality evidence) and to less weight gain (mean difference (MD) -0.5 g/kg/day; 95% CI -0.75 to -0.25; low-quality evidence) than standard RUTF. We do not know whether the cheaper RUTF improved mortality (very low quality evidence).

AUTHORS' CONCLUSIONS

Given the limited evidence base currently available, it is not possible to reach definitive conclusions regarding differences in clinical outcomes in children with severe acute malnutrition who were given home-based ready-to-use therapeutic food (RUTF) compared to the standard diet, or who were treated with RUTF in different daily amounts or formulations. For this reason, either RUTF or flour porridge can be used to treat children at home depending on availability, affordability and practicality. Well-designed, adequately powered pragmatic randomised controlled trials of HIV-uninfected and HIV-infected children with severe acute malnutrition are needed.

Health outcomes of HIV-exposed uninfected African infants

OBJECTIVES

To evaluate severe (grade 3/4) morbidity and mortality in HIV-exposed, uninfected infants.

DESIGN

: Secondary data analysis of The Breastfeeding, Antiretrovirals, and Nutrition (BAN) clinical trial.

METHODS

BAN randomized 2369 mother-infant pairs to maternal, infant, or no extended antiretroviral prophylaxis during breastfeeding. Morbidity outcomes examined were pneumonia/serious febrile illness, diarrhea/growth faltering, and malaria. Infant death was defined as neonatal (≤30 days of life), and postneonatal (31 days to 48 weeks of life). Cox proportional hazards models were used to evaluate the effect of covariates on infant morbidity and mortality.

RESULTS

The rate of pneumonia/serious febrile illness was highest in the first 12 weeks (0.83/100 person-weeks) before rapidly decreasing; rates of all morbidity outcomes increased after 24 weeks. Rates of pneumonia/serious febrile illness and diarrhea/growth faltering were higher during the rainy season. Prophylactic infant cotrimoxazole significantly decreased the rates of all morbidity outcomes. White blood cell (WBC) count less than 9000/μl at birth was associated with increased diarrhea/growth faltering [adjusted hazard ratio (aHR) 1.73, P = 0.04] and malaria (aHR 2.18, P = 0.02). Low birth weight (2000-2499 g) was associated with neonatal death (aHR 12.3, P < 0.001). Factors associated with postneonatal death included rainy season (aHR 4.24, P = 0.002), infant cotrimoxazole (aHR 0.48, P = 0.03), and low infant WBC count at birth (aHR 2.53, P = 0.02).

CONCLUSION

Infant morbidity rates increased after 24 weeks, when BAN infants weaned. Introduction of prophylactic cotrimoxazole was associated with reduced rates of morbidity and mortality in HIV-exposed uninfected infants. Unexpectedly, a low WBC count at birth was significantly associated with later infant morbidity and mortality in this cohort.

Development of a cross-over randomized trial method to determine the acceptability and safety of novel ready-to-use therapeutic foods

OBJECTIVE

To develop a method for determining the acceptability and safety of ready-to-use therapeutic foods (RUTF) before clinical trialing. Acceptability was defined using a combination of three consumption, nine safety, and six preference criteria. These were used to compare a soy/maize/sorghum RUTF (SMS-RUTFh), designed for the rehabilitation of human immunodeficiency virus/tuberculosis (HIV/TB) wasted adults, with a peanut-butter/milk-powder paste (P-RUTF; brand: Plumpy'nut) designed for pediatric treatment.

METHODS

A cross-over, randomized, controlled trial was conducted in Kenya. Ten days of repeated measures of product intake by 41 HIV/TB patients, >18 y old, body mass index (BMI) 18-24 kg · m(-2), 250 g were offered daily under direct observation as a replacement lunch meal. Consumption, comorbidity, and preferences were recorded.

RESULTS

The study arms had similar age, sex, marital status, initial BMI, and middle upper-arm circumference. No carryover effect or serious adverse events were found. SMS-RUTFh energy intake was not statistically different from the control, when adjusted for BMI on day 1, and the presence of throat sores. General preference, taste, and sweetness scores were higher for SMS-RUTFh compared to the control (P < 0.05). Most consumption, safety, and preference criteria for SMS-RUTFh were satisfied except for the average number of days of nausea (0.16 versus 0.09 d) and vomiting (0.04 versus 0.02 d), which occurred with a higher frequency (P < 0.05).

CONCLUSION

SMS-RUTFh appears to be acceptable and can be safely clinically trialed, if close monitoring of vomiting and nausea is included. The method reported here is a useful and feasible approach for testing the acceptability of ready-to-use foods in low income countries.

Impact of Daily versus Weekly Supply of Locally Produced Ready-to-Use Food on Growth of Moderately Wasted Children on Nias Island, Indonesia

This study reports the outcomes of daily (semi-urban areas) and weekly (remote rural regions) programs for moderately wasted children supplemented with locally produced ready-to-use foods in the form of fortified cereal/nut/legume-based biscuits on Nias Island, Indonesia (RUF-Nias biscuit). Thirty-four children in daily and twenty children in weekly programs aged ≥6 to <60 months with weight-for-height z-score (WHZ) ≥ -3 to < -2 SD were recruited (October 2007-June 2008) on Nias and admitted into existing nutrition centers in the Church World Service project area. Individual discharge criterion was WHZ ≥ -1.5 SD. Weight gain of the children in daily and weekly programs was 3.9 ± 3.8 and 2.0 ± 2.0 g/kg/day, respectively. A higher proportion of children in daily than weekly programs reached target WHZ (76% vs. 35%, P = 0.004). Weight gain at program discharge/closure was highly predicted (R (2) = 0.228, P < 0.001) by compliance to RUF biscuits: high vs. low compliance resulted in a 1.33 (95% CI 0.16 to 1.53) g/kg/day higher weight gain. Compliance and admission in daily programs were significant factors in reducing the risk of not reaching the discharge criterion. However, mothers complained more frequently about time constraints in the daily relative to weekly programs.

Nutritional supplementation: the additional costs of managing children infected with HIV in resource-constrained settings

OBJECTIVE

To explore the financial implications of applying the WHO guidelines for the nutritional management of HIV-infected children in a rural South African HIV programme.

METHODS

WHO guidelines describe Nutritional Care Plans (NCPs) for three categories of HIV-infected children: NCP-A: growing adequately; NCP-B: weight-for-age z-score (WAZ) ≤-2 but no evidence of severe acute malnutrition (SAM), confirmed weight loss/growth curve flattening, or condition with increased nutritional needs (e.g. tuberculosis); NCP-C: SAM. In resource-constrained settings, children requiring NCP-B or NCP-C usually need supplementation to achieve the additional energy recommendation. We estimated the proportion of children initiating antiretroviral treatment (ART) in the Hlabisa HIV Programme who would have been eligible for supplementation in 2010. The cost of supplying 26-weeks supplementation as a proportion of the cost of supplying ART to the same group was calculated.

RESULTS

A total of 251 children aged 6 months to 14 years initiated ART. Eighty-eight required 6-month NCP-B, including 41 with a WAZ ≤-2 (no evidence of SAM) and 47 with a WAZ >-2 with co-existent morbidities including tuberculosis. Additionally, 25 children had SAM and required 10-weeks NCP-C followed by 16-weeks NCP-B. Thus, 113 of 251 (45%) children were eligible for nutritional supplementation at an estimated overall cost of $11 136, using 2010 exchange rates. These costs are an estimated additional 11.6% to that of supplying 26-week ART to the 251 children initiated.

CONCLUSIONS

It is essential to address nutritional needs of HIV-infected children to optimise their health outcomes. Nutritional supplementation should be integral to, and budgeted for, in HIV programmes.

Community management of acute malnutrition in the developing world

Globally, acute malnutrition triggers more than 50% of childhood mortality in children under 5 years old, which implies that about 3.5 million children die of malnutrition each year. Prior to the advent of ready-to-use therapeutic food (RUTF), the management of acute malnutrition was limited to hospitals, resulting in low coverage rates with high mortality, as malnourished cases were indentified at later stages often plagued with complications. However, current availability of RUTF has enabled malnourished children to be treated at communities. Further, because RUTF is dehydrated and sealed, it has the added advantage of a lower risk of bacterial contamination, thereby prolonging its storage life at room temperature. Recent data indicate that Community Management of Acute Malnutrition (CMAM) is as cost effective as other high-impact public health measures such as oral rehydration therapy for acute diarrheal diseases, vitamin A supplementation, and antibiotic treatment for acute respiratory infections. Despite the high efficacy of CMAM programs, CMAM still draws insufficient attention for global implementation, suggesting that CMAM programs should be integrated into local or regional routine health systems. Knowledge gaps requiring further research include: the definition of practical screening criteria for malnourished children at communities, the need for systematic antibiotic therapy during malnutrition treatment, and the dietary management of severe malnutrition in children below 6 months of age.

Mid-upper arm circumference based nutrition programming: evidence for a new approach in regions with high burden of acute malnutrition

Background

In therapeutic feeding programs (TFP), mid-upper arm circumference (MUAC) shows advantages over weight-for-height Z score (WHZ) and is recommended by the World Health Organization (WHO) as an independent criterion for screening children 6–59 months old. Here we report outcomes and treatment response from a TFP using MUAC ≤118 mm or oedema as sole admission criteria for severe acute malnutrition (SAM).

Methods

Patient data from September 2007 to March 2009 for children admitted by MUAC ≤118 mm or oedema to a Médecins Sans Frontières (MSF) TFP in Burkina Faso were retrospectively analyzed. Analysis included anthropometric measurements at admission and discharge, program outcomes and treatment response.

Results

Of 24,792 patient outcomes analyzed, nearly half (48.8%; n = 12,090) were admitted with MUAC 116–118 mm. Most patients (88.7%; n = 21,983) were 6–24 months old. At admission, 52.7% (n = 5,041) of those with MUAC 116–118 mm had a WHZ <−3 SD. At discharge, 89.1% (n = 22,094) recovered (15% weight gain or oedema resolution), 7.9% (n = 1,961) defaulted, 1.5% (n = 384) failed to respond to treatment, and 1.0% (n = 260) died. Average weight gain was 5.4 g/kg/day, and average MUAC gain was 0.42 mm/day. Patients with MUAC ≤114 mm at admission had higher average daily weight and MUAC gains at discharge compared to those admitted with MUAC 116–118 mm, but those in the latter category required longer lengths of stay to achieve recovery (P<0.001).

Conclusion

This analysis suggests that MUAC ≤118 mm as TFP admission criterion is a useful alternative to WHZ. Regarding treatment response, rates of weight and MUAC gain were acceptable. Applying 15% weight gain as discharge criterion resulted in longer lengths of stay for less malnourished children. Since MUAC gain parallels weight gain, it may be feasible to use MUAC as both an admission and discharge criterion.

Cost analysis of community-based daily and weekly programs for treatment of moderate and mild wasting among children on Nias Island, Indonesia

BACKGROUND

Ready-to-use food in the form of biscuits (RUF-Nias biscuit) was locally produced for rehabilitation of moderately and mildly wasted (weight-for-height z-score > or = -3 to < -1.5 SD) children on Nias Island, Indonesia. Daily programs were performed in semiurban settings, and weekly programs took place in rural areas.

OBJECTIVE

To analyze the cost of daily and weekly distribution and supervision of RUF-Nias biscuit programs.

METHODS

The costs of the daily and weekly programs were derived from the financial report and interviews with program implementers and participating households. Costs were calculated on the basis of total rehabilitation costs per child per day required to achieve a target weight-for-height z-score > or = -1.5 SD in daily and weekly programs.

RESULTS

Institutional costs to the implementing organization were similar for both programs (approximately US $4 per child per day). The daily programs resulted in a significantly higher proportion of recovered children (78.6% vs. 65.4%) and higher weight gain (3.7 vs. 2.2 g/kg/day) than the weekly programs. About 6% to 7% of the total cost of the programs was accounted for by locally produced RUF-Nias biscuits. The social cost borne by the community for the weekly programs was about half that for the daily programs.

CONCLUSIONS

The daily programs achieved better results for the implementing organization than the weekly programs; however, the weekly programs were preferred by the community because of the lower time constraints and the lower opportunity cost of time. The willingness of community and household members to invest their time in more intensive activities in the daily programs led to better program outcomes.

Treatment of moderate acute malnutrition with ready-to-use supplementary food results in higher overall recovery rates compared with a corn-soya blend in children in southern Ethiopia: an operations research trial

BACKGROUND

Moderate and severe acute malnutrition affects 13% of children <5 y of age worldwide. Severe acute malnutrition affects fewer children but is associated with higher rates of mortality and morbidity. Supplementary feeding programs aim to treat moderate acute malnutrition and prevent the deterioration to severe acute malnutrition.

OBJECTIVE

The aim was to compare recovery rates of children with moderate acute malnutrition in supplementary feeding programs by using the newly recommended ration of ready-to-use supplementary food (RUSF) and the more conventional ration of corn-soya blend (CSB) in Ethiopia.

DESIGN

A total of 1125 children aged 6-60 mo with moderate acute malnutrition received 16 wk of CSB or RUSF. Children were randomly assigned to receive one or the other food. The daily rations were purposely based on the conventional treatment rations distributed at the time of the study in Ethiopia: 300 g CSB and 32 g vegetable oil in the control group (1413 kcal) and 92 g RUSF in the intervention group (500 kcal). The higher ration size of CSB was provided because of expected food sharing.

RESULTS

The HR for children in the CSB group was 0.85 (95% CI: 0.73, 0.99), which indicated that they had 15% lower recovery (P = 0.039). Recovery rates of children at the end of the 16-wk treatment period trended higher in the RUSF group (73%) than in the CSB group (67%) (P = 0.056).

CONCLUSION

In comparison with CSB, the treatment of moderate acute malnutrition with RUSF resulted in higher recovery rates in children, despite the large ration size and higher energy content of the conventional CSB ration.

The effect of adding ready-to-use supplementary food to a general food distribution on child nutritional status and morbidity: a cluster-randomized controlled trial

BACKGROUND

Recently, operational organizations active in child nutrition in developing countries have suggested that blanket feeding strategies be adopted to enable the prevention of child wasting. A new range of nutritional supplements is now available, with claims that they can prevent wasting in populations at risk of periodic food shortages. Evidence is lacking as to the effectiveness of such preventive interventions. This study examined the effect of a ready-to-use supplementary food (RUSF) on the prevention of wasting in 6- to 36-mo-old children within the framework of a general food distribution program.

METHODS AND FINDINGS

We conducted a two-arm cluster-randomized controlled pragmatic intervention study in a sample of 1,038 children aged 6 to 36 mo in the city of Abeche, Chad. Both arms were included in a general food distribution program providing staple foods. The intervention group was given a daily 46 g of RUSF for 4 mo. Anthropometric measurements and morbidity were recorded monthly. Adding RUSF to a package of monthly household food rations for households containing a child assigned to the intervention group did not result in a reduction in cumulative incidence of wasting (incidence risk ratio: 0.86; 95% CI: 0.67, 1.11; p = 0.25). However, the intervention group had a modestly higher gain in height-for-age (+0.03 Z-score/mo; 95% CI: 0.01, 0.04; p<0.001). In addition, children in the intervention group had a significantly higher hemoglobin concentration at the end of the study than children in the control group (+3.8 g/l; 95% CI: 0.6, 7.0; p = 0.02), thereby reducing the odds of anemia (odds ratio: 0.52; 95% CI: 0.34, 0.82; p = 0.004). Adding RUSF also resulted in a significantly lower risk of self-reported diarrhea (-29.3%; 95% CI: 20.5, 37.2; p<0.001) and fever episodes (-22.5%; 95% CI: 14.0, 30.2; p<0.001). Limitations of this study include that the projected sample size was not fully attained and that significantly fewer children from the control group were present at follow-up sessions.

CONCLUSIONS

Providing RUSF as part of a general food distribution resulted in improvements in hemoglobin status and small improvements in linear growth, accompanied by an apparent reduction in morbidity.

An effectiveness trial showed lipid-based nutrient supplementation but not corn-soya blend offered a modest benefit in weight gain among 6- to 18-month-old underweight children in rural Malawi

OBJECTIVE

To determine if supplementation with corn-soya blend (CSB) or lipid-based nutrient supplement (LNS) improved the weight gain of moderately underweight infants and children when provided through the national health service.

DESIGN

A randomised, controlled, assessor-blinded clinical trial. Infants and children were randomised to receive for 12 weeks an average daily ration of 71 g CSB or 43 g LNS, providing 1188 kJ and 920 kJ, respectively, or no supplement (control). Main outcome was weight gain. Secondary outcomes included changes in anthropometric indices and incidence of serious adverse events. Intention-to-treat analyses were used.

SETTING

Kukalanga, Koche, Katema and Jalasi health centres in Mangochi District, rural Malawi.

SUBJECTS

Underweight (weight-for-age Z-score <-2) infants and children aged 6-15 months (n 299).

RESULTS

Mean weight gain was 630 g, 680 g and 750 g in control, CSB and LNS groups, respectively (P = 0·21). When adjusted for baseline age, children receiving LNS gained on average 90 g more weight (P = 0·185) and their weight-for-length Z-score increased 0·22 more (P = 0·049) compared with those receiving no supplementation. No statistically significant differences were observed between the CSB and control groups in mean weight and length gain.

CONCLUSIONS

LNS supplementation provided during the lean season via through the national health service was associated with a modest increase in weight. However, the effect size was lower than that previously reported under more controlled research settings.

Intra-household use and acceptability of Ready-to-Use-Supplementary-Foods distributed in Niger between July and December 2010

Few studies have looked at consumption of Ready-to-Use-Supplementary-Foods (RUSFs) during a nutritional emergency. Here, we describe the use and acceptability of RUSF within households in four districts of the region of Maradi, Niger during large scale preventive distributions with RUSF in 2010 targeted at children 6-35months of age. Our study comprised both quantitative and qualitative components to collect detailed information and to allow in-depth interviews. We performed a cross-sectional survey in 16 villages between two monthly distributions of RUSF (October-November 2010). All households with at least one child who received RUSF were included and a total of 1842 caregivers were interviewed using a structured questionnaire. Focus groups and individual interviews of 128 caregivers were conducted in eight of the selected villages. On average, 24.7% of households reported any sharing of RUSF within the household. Sharing practices outside the household remained rare. Most of the sharing reported occurred among children under 5years of age living in the household. On average, 91% of caregivers in all districts rated the child's appreciation of the products as good or very good. Program planning may need to explicitly accounting for the sharing of products among children under 5 within household.

Program responses to acute and chronic malnutrition: divergences and convergences

Program approaches for addressing acute malnutrition and those for addressing chronic malnutrition have grown in different directions. Their specialization has led to productive advances in the efficacy of specific interventions but has also created divergences in implementation. Greater convergence and integration between the 2 sets of approaches would help programs respond to the diversity of conditions faced in the field and enable a more comprehensive continuum of care from prevention to treatment. After reviewing the causes of the differences in approach, this paper examines programmatic and scientific challenges to greater convergence and suggests steps to promote effective integration of acute and chronic malnutrition services. Steps include strengthening community linkages between program platforms, assessing the degree and type of integration needed in various situations, identifying cost efficiencies, and developing joint tools where possible.

A lipid-based nutrient supplement mitigates weight loss among HIV-infected women in a factorial randomized trial to prevent mother-to-child transmission during exclusive breastfeeding

BACKGROUND

Breastfeeding increases metabolic demands on the mother, and excessive postnatal weight loss increases maternal mortality.

OBJECTIVE

We evaluated the efficacy of a lipid-based nutrient supplement (LNS) for prevention of excess weight loss in breastfeeding, HIV-infected women.

DESIGN

The BAN (Breastfeeding, Antiretrovirals, and Nutrition) Study was a randomized controlled trial in Lilongwe, Malawi. At delivery, HIV-infected mothers and their infants were randomly assigned according to a 2-arm (with and without LNS) by 3-arm (maternal triple-antiretroviral prophylaxis, infant-nevirapine prophylaxis, or neither) factorial design. The 28-wk LNS intervention provided daily energy (700 kcal), protein (20 g), and micronutrients (except for vitamin A) to meet lactation needs. Women were counseled to breastfeed exclusively for 24 wk and to wean by 28 wk. Weight change (0-28 wk) was tested in an intent-to-treat analysis by using 2-factor ANOVA and with longitudinal mixed-effects models.

RESULTS

At delivery, the LNS (n = 1184) and control (n = 1185) groups had similar mean weights and BMIs. Women receiving the LNS had less 0-28-wk weight loss (-1.97 compared with -2.56 kg, P = 0.003). This difference remained significant after adjustment for maternal antiretroviral drug therapy and baseline BMI. Women receiving antiretroviral drugs had more weight loss than did those not receiving antiretroviral drugs (-2.93 compared with -1.90 kg, P < 0.001). The benefit of the LNS for reducing weight loss was observed both in those receiving antiretroviral drugs (-2.56 compared with -3.32 kg, P = 0.019) and in those not receiving antiretroviral drugs (-1.63 compared with -2.16 kg, P = 0.034).

CONCLUSIONS

The LNS reduced weight loss among HIV-infected, breastfeeding women, both in those taking maternal antiretroviral prophylaxis to prevent postnatal HIV transmission and in those not receiving antiretroviral prophylaxis. Provision of an LNS may benefit HIV-infected, breastfeeding women in resource-limited settings. This trial was registered at clinicaltrials.gov as NCT00164762.

Monitoring the adequacy of catch-up growth among moderately malnourished children receiving home-based therapy using mid-upper arm circumference in southern Malawi

Each year more children die from moderate than severe malnutrition. Home-based therapy (HBT) using Ready-to-Use Therapeutic Foods (RUTF) has proven to successfully treat uncomplicated childhood malnutrition on an outpatient basis. This study attempts to discern if Mid-upper Arm Circumference (MUAC) measurements collected by community-based health aides have the potential to monitor changes in nutritional status among moderately malnourished Malawian children while undergoing HBT using RUTF. Retrospective analysis was performed using the anthropometric data of 1,904 moderately malnourished children during treatment using RUTF. Changes in MUAC and changes in overall weight at 1 and 2 months of treatment were compared. Various geometric relationships were explored between the measures to find the most direct relationship. Models were developed to investigate anthropometric changes in children undergoing treatment. These data reveal that the correlation between the changes in MUAC and changes in weight over the course of treatment is statistically significant (P < 0.0001). The relationship between a child's change in MUAC and their change in weight is influenced by several cofactors related to their initial presentation. The power of change in weight to predict change in MUAC increases at the second month of treatment. Statistical modelling improves if children under the age of 12 months are omitted. Changes in MUAC reflect changes in overall body mass among moderately malnourished children undergoing HBT using RUTF suggesting that performance could possibly be monitored by village health aides in order to monitor a child's performance on feeding programmes in low resource settings.

Home-Based Treatment of Acute Malnutrition in Cambodian Urban Poor Communities

Background

The prevalence of malnutrition in Cambodia is among the highest in Southeast Asia. Until recently, there has been a consensus that the treatment and rehabilitation of acutely severely malnourished children should take place in hospitals; however, limited local health resources often place constraints upon the inpatient management of these children.

Objective

This study reviews the outcomes of a community nutrition program designed to rehabilitate children under the age of 5 years with moderate or severe acute malnutrition living in a poor urban community in Phnom Penh, Cambodia.

Methods

Clinical records of the program participants during the period from January 1999 to November 2006 were reviewed. Attainment of recovery weight-for-height z-scores, the length of time taken to achieve this recovery, rates of weight gain, mortality rate, and rate of default were determined from the data.

Results

One hundred fifty-nine children aged 4 years or younger with a mean admission weight-for-height z-score of −3.3 were treated. The mean outcome weight-for-height z-score was −1.5. Eighty-seven children (55%) reached a weight-for-height z-score ≥ −1 over a mean period of 14 weeks of rehabilitation. The average rate of weight gain was 4 g/kg/day. The case fatality rate was 5.6%.

Conclusions

This program is an example of effective, community-based rehabilitation of children with moderate or severe acute malnutrition in an urban, Southeast Asian, non-humanitarian-relief context, through a combination of nutritional education, regular home visiting, and food support.

The acceptance and feasibility of replacement feeding at 6 months as an HIV prevention method in Lilongwe, Malawi: results from the BAN study

International guidelines recommend EBF to age 6 months among HIV-infected mothers choosing to breast-feed and cessation thereafter if replacement feeding is acceptable, feasible, affordable, sustainable, and safe. When mothers wean, they are challenged to provide an adequate replacement diet. This study investigates the use and acceptability of a lipid-based nutrient supplement (LNS) as a breast-milk substitute when provided to infants (6-12 mo) of HIV-positive mothers, as part of the Breast-feeding, Antiretroviral, and Nutrition (BAN) Study. A sub-sample of mothers (n = 45) participated in interviews that explored EBF, weaning, and strategies to feed LNS. Mothers reported several weaning strategies, including gradual reduction of breast-feeding, expressing breast-milk into a cup, and separation of mother and child. LNS, a peanut-based micronutrient fortified paste, was highly accepted and incorporated into the traditional diet. Weaning is a feasible HIV prevention method among this population in Malawi when supported by the provision of LNS as a breast-milk substitute.

Acceptability of three novel lipid-based nutrient supplements among Malawian infants and their caregivers

We tested the acceptability of three new lipid-based nutrient supplements (LNSs) in two independent phases among 18 8-12-month-old healthy rural Malawians and their caregivers. In phase 1, acceptability was assessed by offering three new LNSs in random order, and an LNS already determined to be acceptable, Nutributter(®), each added to 30 g of warm maize porridge over three consecutive days. In phase 2, infants from each village were provided one of the new supplements for a 2-week home-use trial. Outcome measures included the amount consumed, time completion of the dose and the maternal rating of likeability on a 5-point scale. The supplements were rated acceptable if consumption was over 50% of the offered dose in phase 1. The mean (95% confidence interval) proportion of the LNS test meals consumed under direct observation was 88% (82-94%) for LNS-10gM, 90% (84-95%) for LNS-20gM, 87% (79-95%) for LNS-20gNoM, and 86% (83-90%) for Nutributter. The median (25th and 75th centile) time (minutes) for completing the offered test meal was 4 (2, 7) for LNS-10gM, 5 (3, 6) for LNS-20gM, 4 (3, 8) for LNS-20gNoM and 4 (2, 6) for Nutributter. During both phases, almost all caregivers rated all study foods very likeable for themselves and their children, with mean scores slightly lower among the caregivers than among the infants. In the home-use phase, the test foods were almost exclusively used by the study participants with minimal sharing with siblings and other household members. Some infants were reported to prefer the new investigational products over traditional complementary food. Considering that the novel LNS was largely acceptable. Efficacy trials are now needed to assess their impact on child growth and development.

Efficacy and safety of therapeutic nutrition products for home based therapeutic nutrition for severe acute malnutrition a systematic review

CONTEXT

Severe acute malnutrition (SAM) in children is a significant public health problem in India with associated increased morbidity and mortality. The current WHO recommendations on management of SAM are based on facility based treatment. Given the large number of children with SAM in India and the involved costs to the care-provider as well as the care-seeker, incorporation of alternative strategies like home based management of uncomplicated SAM is important. The present review assesses (a) the efficacy and safety of home based management of SAM using therapeutic nutrition products or ready to use therapeutic foods (RUTF); and (b) efficacy of these products in comparison with F-100 and home-based diet.

EVIDENCE ACQUISITION

Electronic database (Pubmed and Cochrane Controlled Trials Register) were scanned using keywords severe malnutrition, therapy, diet, ready to use foods and RUTF. Bibliographics of identified articles, reviews and books were scanned. The information was extracted from the identified papers and graded according to the CEBM guidelines.

RESULTS

Eighteen published papers (2 systematic reviews, 7 controlled trials, 7 observational trials and 2 consensus statements) were identified. Systematic reviews and RCTs showed RUTF to be at least as efficacious as F-100 in increasing weight (WMD=3.0 g/kg/day; 95% CI -1.70, 7.70) and more effective in comparison to home based dietary therapies. Locally made RUTFs were as effective as imported RUTFs (WMD=0.07 g/kg/d; 95% CI=-0.15, 0.29). Data from observational studies showed the energy intake with RUTF to be comparable to F-100. The pooled recovery rate, mortality and default in treatment with RUTF was 88.3%, 0.7% and 3.6%, respectively with a mean weight gain of 3.2 g/kg/day. The two consensus statements supported the use of RUTF for home based management of uncomplicated SAM.

CONCLUSIONS

The use of therapeutic nutrition products like RUTF for home based management of uncomplicated SAM appears to be safe and efficacious. However, most of the evidence on this promising strategy has emerged from observational studies conducted in emergency settings in Africa. There is need to generate more robust evidence, design similar products locally and establish their efficacy and cost-effectiveness in a non-emergency setting, particularly in the Indian context.

Nutrition outcomes of HIV-infected malnourished adults treated with ready-to-use therapeutic food in sub-Saharan Africa: a longitudinal study

BACKGROUND

Among people living with HIV/AIDS, nutritional support is increasingly recognized as a critical part of the essential package of care, especially for patients in sub-Saharan Africa. The objectives of the study were to evaluate the outcomes of HIV-positive malnourished adults treated with ready-to-use therapeutic food and to identify factors associated with nutrition programme failure.

METHODS

We present results from a retrospective cohort analysis of patients aged 15 years or older with a body mass index of less than 17 kg/m² enrolled in three HIV/AIDS care programmes in Africa between March 2006 and August 2008. Factors associated with nutrition programme failure (patients discharged uncured after six or more months of nutritional care, defaulting from nutritional care, remaining in nutritional care for six or more months, or dead) were investigated using multiple logistic regression.

RESULTS

Overall, 1340 of 8685 (15.4%) HIV-positive adults were enrolled in the nutrition programme. At admission, median body mass index was 15.8 kg/m² (IQR 14.9-16.4) and 12% received combination antiretroviral therapy (ART). After a median of four months of follow up (IQR 2.2-6.1), 524 of 1106 (47.4%) patients were considered cured. An overall total of 531 of 1106 (48.0%) patients failed nutrition therapy, 132 (11.9%) of whom died and 250 (22.6%) defaulted from care. Men (OR = 1.5, 95% CI 1.2-2.0), patients with severe malnutrition at nutrition programme enrolment (OR = 2.2, 95% CI 1.7-2.8), and those never started on ART (OR = 4.5, 95% CI 2.7-7.7 for those eligible; OR = 1.6, 95% CI 1.0-2.5 for those ineligible for ART at enrolment) were at increased risk of nutrition programme failure. Diagnosed tuberculosis at nutrition programme admission or during follow up, and presence of diarrhoeal disease or extensive candidiasis at admission, were unrelated to nutrition programme failure.

CONCLUSIONS

Concomitant administration of ART and ready-to-use therapeutic food increases the chances of nutritional recovery in these high-risk patients. While adequate nutrition is necessary to treat malnourished HIV patients, development of improved strategies for the management of severely malnourished patients with HIV/AIDS are urgently needed.
