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

Qualitative study of acceptability, benefits, and feasibility of a food-based intervention among participants and stakeholders of the RATIONS trial

A qualitative study was conducted during the RATIONS trial to explore the perceptions, experiences, and expectations of participants and stakeholders on the acceptability, benefits, and feasibility of the nutritional intervention to complement the trial findings for deeper exploration into why and how of these findings and other allied themes. Using purposive sampling, we recruited 58 individuals for 22 in-depth interviews (IDI) and four focus group discussions (FGDs) between January and June 2022. These included 12 patients with TB, six household contacts, and other stakeholders (18 trial members, 18 government community workers, and four National TB Elimination Program (NTEP) staff). All IDIs and FGDs were audio-recorded, transcribed, and translated. The codes were generated using an inductive process and categorized manually into themes, with direct quotes describing the themes. The intervention was found to be acceptable in terms of cultural compatibility, quality, quantity, and duration; considered beneficial in helping tolerate the adverse effects of medications, weight gain, and resuming work; and was considered life-saving by many during the COVID-19 pandemic. Other observations included food-sharing in the control arm, inability to regain pre-disease functional status despite weight gain, and preference for in-kind support. Community health workers expressed confidence in its feasibility and willingness to take responsibility for its implementation. The NTEP staff considered it feasible if necessary resources were provided. This qualitative inquiry reflected the perspectives and lived experiences of households experiencing poverty, food insecurity, TB and the stakeholders serving them. Their voices are relevant in framing policy and practice in the NTEP and future research in India and similar low-resource settings. The food-based intervention was perceived as acceptable, feasible, and beneficial for the recipients and the NTEP. Opinion on cash or support in kind was divided; many preferred in-kind support over cash, but others expressed a requirement for both.

Locally Prepared Therapeutic Food for Treatment of Severely Underweight Children in Rural India: An Interventional Prospective Controlled Community-Based Study with Long Follow-Up:-'SAMMAN' Trial

BACKGROUND

Severely underweight (SUW) children contribute significantly to under-five mortality and morbidity. There are WHO guidelines for the management of severe acute malnutrition but no specific guidelines for SUW management.

OBJECTIVE

The objectives were to achieve a recovery rate of 30% at 90 days of treatment for severe underweight (SUW) children aged 6-60 months, compare changes in weight-for-age Z (WAZ) scores, growth patterns, and case fatality rates between intervention and reference arms (RA), and reduce the prevalence of SUW in the intervention arm (IA). The target of a 30% recovery rate was achievable and significant based on our past research conducted in similar settings.

METHODS

Design: A prospective controlled community-based, longitudinal, two arms (IA, RA), intervention study with long follow-up was conducted between January 2011 and October 2023.

SETTING

Primary care for participants from 14 villages in rural Melghat, India.

PARTICIPANTS

The study participants included SUW children aged 6-60 months and age-matched (±2 weeks) normal controls. The SAMMAN (Acronym for SAM-Management) intervention was comprised of local therapeutic food-micronutrient (LTF-MN) therapy for 90 days, intensive behavior change communication, infection treatment, and quarterly anthropometric records. SUW recovery, growth patterns, case fatality rate, prevalence at 90 days of therapy and at 60 months of age, and survival until early adolescence were assessed. ANCOVA analysis was used to obtain changes in Z-scores.

RESULTS

In the IA, the recovery rate was 36.8% at 90 days and 78.2% at 60 months of age. The mean difference in change in WAZ scores between the intervention arm and the reference arm was statistically significant (p < 0.0001). Growth patterns were similar between the two arms up to early adolescence. The SUW case fatality rate was significantly lower in the IA (0.9%) as compared to 4.62% in the RA at 60 months (p = 0.022). The reduction in SUW prevalence in intervention villages was higher than in the control villages (p < 0.001). The cost of management per SUW child was 3888 INR (47 USD) less than RUTF.

CONCLUSION

The SAMMAN intervention is safe and cost-effective for significantly improving WAZ scores, sustainable, and hence replicable in resource-limited areas.

Acceptability of Locally Produced Ready to Use Therapeutic Food (RUTF) in Malnourished Children: A Randomized, Double-Blind, Crossover Study

OBJECTIVE

To compare the acceptability of a locally produced ready-to-use therapeutic food (L-RUTF) with the standard ready-to-use therapeutic food (S-RUTF).

METHODS

It was a single-center, randomized, double-blind, two-way crossover study. The participants were 6-59-mo-old children residing in an urban slum, with weight-for-height z score (WHZ) < -2SD. The study had two intervention periods of feeding with two types of RUTF- L-RUTF and S-RUTF-for a period of 24 h, separated by a wash-out period of 7 d. The outcome measures were the acceptability measured as consumption of more than two-thirds of the total calories offered (150 kcal/kg/24 h) and the degree of liking of the food measured by organoleptic evaluation.

RESULT

Both types of RUTF did not qualify as acceptable. L-RUTF was preferred over S-RUTF in organoleptic evaluation.

CONCLUSION

The study suggests that RUTF products are not suitable for use as a single therapeutic food during nutrition rehabilitation of children with acute malnutrition. The study was registered in the clinical registry of India; Reg. No: CTRI/2018/04/012967.

Design, development, and local production of lipid-based nutritional supplements to enhance the complementary feeding diet: A model for collaboration for a feeding trial in Bangladesh

Background: Lipid-based nutrient supplements (LNS) are effective for treating childhood wasting and for preventing stunting, wasting, and anemia, but large-scale production and programmatic use are a barrier. Locally-developed and produced LNS may be more affordable and reduce logistical procurement and importation hurdles, while promoting private sector engagement and partnership. Methods: In northwestern Bangladesh, we conducted a community-based trial of complementary food supplementation to test its efficacy to reduce childhood stunting. Two locally-developed, small-quantity LNS (20g/day, rice-lentil and chick-pea based) were designed, developed first at small scale in the ‘kitchen’ laboratory under controlled conditions, followed by taking them to a local food manufacturer for larger production for the study. We describe here the partnership, required expertise and capacity, experiences, and lessons learned that made this uniquely complex undertaking possible Results: Key steps in the journey included addressing the dynamics of clear communication between partners, executing on carefully assigned tasks and roles, correcting course when needed, and maintaining timeliness and roadmaps. Knowledge of food science and technology was key in solving many food-production challenges that were encountered in taking the laboratory recipe to the factory. Factory production was established and had to meet quality and hygiene criteria set for young children. Conclusions: We provide documentation of this experience as a model to describe the various steps and considerations and what is entailed in local LNS production. We highlight the importance of a well-conceived collaboration with clear roles that created a ‘win-win’ situation for all partners for achieving common goals, establishing improved technology at the factory, and building new capacity to produce such products for children in a low resource setting. Key words: micronutrient, lipid-based nutrient supplements, maternal and child, malnutrition, multiagency collaboration

Does improved oleic acid content due to marker-assisted introgression of ahFAD2 mutant alleles in peanuts alter its mineral and vitamin composition?

Peanuts (Arachis hypogaea L.) with high oleic acid content have extended shelf life and several health benefits. Oleic, linoleic, and palmitic acid contents in peanuts are regulated by ahFAD2A and ahFAD2B mutant alleles. In the present study, ahFAD2A and ahFAD2B mutant alleles from SunOleic 95R were introgressed into two popular peanut cultivars, GG-7 and TKG19A, followed by markers-assisted selection (MAS) and backcrossing (MABC). A total of 22 MAS and three MABC derived lines were developed with increased oleic acid (78-80%) compared to those of GG 7 (40%) and TKG 19A (50%). Peanut kernel mineral and vitamin composition remained unchanged, while potassium content was altered in high oleic ingression lines. Two introgression lines, HOMS Nos. 37 and 113 had over 10% higher pooled pod yield than respective best check varieties. More than 70% recurrent parent genome recovery was observed in HOMS-37 and HOMS-113 through recombination breeding. However, the absence of recombination in the vicinity of the target locus resulted in its precise introgression along with ample background genome recovery. Selected introgression lines could be released for commercial cultivation based on potential pod yield and oleic acid content.

Evaluation of the outpatient therapeutic program for severe acute malnourished children aged 6-59 months implementation in Dehana District, Northern Ethiopia: a mixed-methods evaluation

Background

In Ethiopia, about 57% of child mortality is associated with acute malnutrition in which the burden is dominant at the rural community. In that regard, the Ethiopian government has been implementing the Outpatient Therapeutic Program (OTP) for managing the uncomplicated sever acute malnutrition among children aged 6 to 59 months at community level by health extension workers. But nothing is known about the implementation status of OTP. Thus, this evaluation aims to evaluate the implementation status of OTP in Dehana district, northern Ethiopia. 

Methods

A facility-based cross-sectional evaluation with concurrent mixed-method was employed from 1st February to 30th April 2020. A total of 39 indicators were used to evaluate the availability, compliance and acceptability dimensions of the program implementation. A total of 422 mothers/caregivers for exit interview, 384 children’s (diagnosed with acute malnutrition) record reviews, nine key informants’ interview, and 63 observations were done in this evaluation. A multi-variable logistic regression analysis was used to identify the predictor variables associated with acceptability. Adjusted Odds Ratio (AOR) with 95% confidence interval (CI), and p-value < 0.05 were used to declare statistically significant variables. The qualitative data were tape recorded, transcribed in Amharic and translated into English and finally thematic analysis was done.

Results

The overall implementation of OTP was 78% measured by availability (87.5%), compliance (75.3%), and acceptability (71.0%) dimensions. Trained healthcare providers, Ready to Use Therapeutic Food (RUTF), Mebendazole, and Oral Rehydration Salt (ORS) were available in all health posts, whereas vitamin A and folic acid were stocked out in some health posts. The health care providers complained that interruption of supplies, work overload and improper usage of RUTF by caregivers were the common challenges of program delivery. Rural residence (AOR = 0.18, 95% CI: 0.09–0.39), knowledge on childhood malnutrition and program services (AOR = 2.27, 95% CI: 1.04–4.97), and had malnourished children previously (AOR = 1.82, 95% CI: 1.01–3.30) were significantly associated with the acceptability of OTP program.

Conclusion

The overall implementation status of OTP was judged fair. Low achievement was observed on the compliance of health care providers to the standards, and acceptability of program services. Therefore, the program needs great improvement to enhance the outcome of childhood malnutrition management.

Early Detection of Mold-Contaminated Peanuts Using Machine Learning and Deep Features Based on Optical Coherence Tomography

Fungal infection is a pre-harvest and post-harvest crisis for farmers of peanuts. In environments with temperatures around 28 °C to 30 °C or relative humidity of approximately 90%, mold-contaminated peanuts have a considerable likelihood to be infected with Aflatoxins. Aflatoxins are known to be highly carcinogenic, posing danger to humans and livestock. In this work, we proposed a new approach for detection of mold-contaminated peanuts at an early stage. The approach employs the optical coherence tomography (OCT) imaging technique and an error-correcting output code (ECOC) based Support Vector Machine (SVM) trained on features extracted using a pre-trained Deep Convolutional Neural Network (DCNN). To this end, mold-contaminated and uncontaminated peanuts were scanned to create a data set of OCT images used for training and evaluation of the ECOC-SVM model. Results showed that the proposed approach is capable of detecting mold-contaminated peanuts with respective accuracies of approximately 85% and 96% after incubation periods of 48 and 96 h.

Acceptability and Adherence to Peanut-Based Energy-Dense Nutritional Supplement Among Adult Malnourished Pulmonary Tuberculosis Patients in Ballabgarh Block of Haryana, India

BACKGROUND

Undernutrition is a leading risk factor for tuberculosis and is associated with adverse treatment outcomes. Energy-dense nutritional supplement (EDNS) may be helpful in managing undernutrition in tuberculosis patients.

METHODS

A longitudinal study was conducted among 102 newly diagnosed pulmonary tuberculosis patients in the Ballabgarh tuberculosis unit in Haryana, India, between September 2018 and February 2019. Participants were provided daily supplementation with 2 sachets of peanut-based EDNS providing 1000 kcal along with the tuberculosis chemotherapy for 2 months. Acceptability was assessed after one month of supplementation. Reported side effects were assessed every 15 days for 2 months and adherence, in terms of proportion of supplement consumed, was assessed on weekly basis for 2 months. Weight was measured at baseline and after 1 month and 2 months.

RESULTS

Mean age of participants was 33 years (standard deviation: 13.8) and 75.5% of the participants were male. Almost 100% of the participants found the taste, smell, consistency, and color of the EDNS acceptable. Three participants rejected it after one month of consuming EDNS and another 7 rejected after 2 months of consuming EDNS. After consuming EDNS for 2 months, 13.9% of the participants complained of nausea, 11.9% complained of vomiting, 10.9% complained of diarrhea, and 9.9% complained of pain in the abdomen and abdominal fullness or bloating anytime during the period of supplementation. The adherence to EDNS among the participants was reported as 92.6%.

CONCLUSION

A peanut-based EDNS was highly acceptable and safe, and the adherence to it was high among patients with pulmonary tuberculosis.

Sensory evaluation and volatile compounds of an alternative ready-to-use therapeutic food for malnourished children

Ready-to-use therapeutic foods (RUTFs) are special foods used to encourage rapid weight gain in 5-year-old malnourished children, avoiding hospitalization. The factors affecting sensory characteristics and acceptability of RUTFs have been not adequately described. The aim of this work was to evaluate both the sensory properties and volatile compounds of four alternative RUTFs, varying in soy and sorghum, icing sugar, and oil content. Nine nonoral sensory attributes were evaluated by nine selected and trained assessors. The perceived intensity of five oral sensory attributes and the overall liking were assessed by 100 adult consumers. The volatile compounds were extracted and concentrated by solid phase microextraction and analyzed by gas chromatography/mass spectrometry. RUTF formulations significantly differed for graininess between fingers (size of granules) (P = 0.007), viscosity (P = 0.013), adhesiveness to the spoon (P < 0.044), and meltability (P = 0.005), but in consumers' opinion, they differed only for difficulty in swallowing, intensity of global odor, flavor, and sweetness. A positive correlation between overall liking and sweetness was found. Volatile compounds arising from lipid oxidation (hexanal and octanoic acid) were positively correlated with global odor and flavor. These attributes negatively affected the overall liking and were mainly contained in one out of the four formulations. Sensory and instrumental characterization identified key attributes for this kind of food, such as difficulty in swallowing, global odor, and sweetness, suggesting how to formulate an alternative RUTF to be used for a future clinical trial on malnourished children. PRACTICAL APPLICATION: Starting from the world's need to fight child malnutrition, the present study tried to characterize alternative ready-to-use therapeutic foods (RUTFs), special foods used to encourage rapid weight gain in 5-year-old malnourished children, from several points of view, such as acceptability, stability, technological, and overall quality. Results obtained will be an aid to setup the technological conditions and scale-up parameters for local productions of RUTFs to be tested in real trials on malnourished children. Indeed, key sensory attributes that drive consumer acceptance for this special food, such as sweetness and difficulty in swallowing, came out from the present study.

Acceptability of locally-produced Ready-to-Use Supplementary Food (RUSF) for children under two years in Cambodia: A cluster randomised trial

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

Lactobacillus rhamnosus Probiotic Food as a Tool for Empowerment Across the Value Chain in Africa

Perhaps by serendipity, but Lactobacillus rhamnosus has emerged from the 1980s as the most researched probiotic species. The many attributes of the two main probiotic strains of the species, L. rhamnosus GG and GR-1, have made them suitable for applications to developing countries in Africa and beyond. Their use with a Streptococcus thermophilus starter strain C106, in the fermentation of milk, millet, and juices has provided a means to reach over 250,000 consumers of the first probiotic food on the continent. The social and economical implications for this translational research are significant, and especially pertinent for people living in poverty, with malnutrition and exposure to environmental toxins and infectious diseases including HIV and malaria. This example of probiotic applications illustrates the power of microbes in positively impacting the lives of women, men, and children, right across the food value chain.

Randomised controlled trial to test the effectiveness of a locally-produced ready-to-use supplementary food (RUSF) in preventing growth faltering and improving micronutrient status for children under two years in Cambodia: a study protocol

BACKGROUND

Existing ready-to-use supplementary and therapeutic foods (RUSFs and RUTFs) have had limited acceptance and effectiveness in Cambodia. This has hampered the treatment and prevention of child malnutrition. An innovative, locally produced, multiple micronutrient fortified lipid-based nutrient supplement (LNS) has been developed for use as an RUSF. Unlike most RUSFs, which contain milk, this product contains fish as the animal protein. Few RUSFs have been formulated using non-milk animal-source foods and they have not been widely tested. An acceptability trial that was conducted on this novel RUSF in June 2015 demonstrated that children will eat the RUSF and that caregivers will feed it to their children. The current trial aims to evaluate the effectiveness of the RUSF in preventing growth faltering and improving micronutrient status in Cambodian children.

METHODS AND ANALYSIS

This trial is a six-month, prospective, cluster randomised, non-blinded controlled trial among infants in peri-urban Phnom Penh. The trial aims to establish the superiority of the novel RUSF, compared to three alternatives (Corn-Soy Blend Plus Plus (CSB++) and Sprinkles micronutrient powders as active comparators, and the unimproved diet as a control). The allocation ratio is 1:1. Healthy children (N = 540) aged six to eleven months will be recruited. Data will be collected at baseline, and monthly thereafter for a period of six months. Participants will be provided with a monthly supply of the food to which their village has been allocated.

DISCUSSION

There is an urgent need to develop locally produced and culturally acceptable RUSFs, and to compare these with existing options in terms of their potential for preventing malnutrition, in Cambodia and elsewhere. This trial will contribute much-needed data on the effectiveness of supplementary foods with an animal-source food other than milk, by comparing a novel RUSF based on fish to one that uses milk (CSB++). Moreover, it will deepen the understanding of the impact of multiple micronutrients provided with or without macronutrients, by comparing the novel RUSF and CSB++, which combine macronutrients with multiple micronutrients, to Sprinkles, which contains no macronutrients. In addition, it will augment the body of evidence from Asia.

Crossover trial to test the acceptability of a locally produced lipid-based nutrient supplement (LNS) for children under 2 years in Cambodia: a study protocol

INTRODUCTION

The acceptability and efficacy of existing ready-to-use supplementary and therapeutic foods has been low in Cambodia, thus limiting success in preventing and treating malnutrition among Cambodian children. In that context, UNICEF and IRD have developed a locally produced, multiple micronutrient fortified lipid-based nutrient supplement. This food is innovative, in that it uses fish instead of milk as the animal source food. Very few supplementary foods have non-milk animal source foods, and in addition they have not been widely tested. This trial will assess the novel food's acceptability to children and caregivers.

METHODS AND ANALYSIS

This is a cluster-randomised, incomplete block, 4×4 crossover design with no blinding. It will take place in four sites in a community setting in periurban Phnom Penh. Healthy children aged 9-23 months (n=100) will eat each of four foods for 3 days at a time. The amount they consume will be measured, and at the end of each 3-day set, caregivers will assess how well their child liked the food. After 12 days, caregivers themselves will do a sensory test of the 4 foods and will rank them in terms of preference.

ETHICS AND DISSEMINATION

Ethical clearance was received from the University of Queensland Medical Research Ethics Committee (2014001070) and from Cambodia's National Ethics Committee for Health Research (03/8 NECHR).

Acceptability of locally produced ready-to-use therapeutic foods in Ethiopia, Ghana, Pakistan and India

Successful treatment of severe acute malnutrition has been achieved with ready-to-use therapeutic food (RUTF), but only 15% of children with severe acute malnutrition receive RUTF. The objective of this study was to determine whether new formulations of RUTF produced using locally available ingredients were acceptable to young children in Ethiopia, Ghana, Pakistan and India. The local RUTFs were formulated using a linear programming tool that allows for inclusion of only local ingredients and minimizes cost. The study consisted of 4 two-arm, crossover, site-randomized food acceptability trials to test the acceptability of an alternative RUTF formula compared with the standard peanut-based RUTF containing powdered milk. Fifty children with moderate wasting in each country were enrolled in the 2-week study. Acceptability was measured by overall consumption, likeability and adverse effects reported by caregivers. Two of the four RUTFs did not include peanut, and all four used alternative dairy proteins rather than milk. The ingredient cost of all of the RUTFs was about 60% of standard RUTF. In Ethiopia, Ghana and India, the local RUTF was tolerated well without increased reports of rash, diarrhoea or vomiting. Children consumed similar amounts of local RUTF and standard RUTF and preferred them similarly as well. In Pakistan, local RUTF was consumed in similar quantities, but mothers perceived that children did not enjoy it as much as standard RUTF. Our results support the further investigation of these local RUTFs in Ethiopia, Ghana and India in equivalency trials and suggest that local RUTFs may be of lower cost.

Impact of therapeutic food compared to oral nutritional supplements on nutritional outcomes in mildly underweight healthy children in a low-medium income society

BACKGROUND & AIMS

Therapeutic foods (RUTF) are used to treat severe acute malnutrition in children 5 years and under in low and middle income countries (LMI), while liquid nutritional supplements (ONS) are used in affluent societies. With globalisation and economic growth in LMI, there will be an inclination to move towards practices applied in affluent countries. This study compared the effect of supplementation with a RUTF and an ONS, on nutritional outcomes in mildly underweight children.

METHODS

68 Pakistani (5-10 y), mildly underweight (weight Z-score: -2 to -1) children randomly received either RUTF or ONS (500 kcal/day), in addition to their habitual diet for four weeks. Weight, height, skinfolds and their changes during intervention, were compared between the two groups and at follow up, post-supplementation.

RESULTS

All nutritional outcomes and height improved with both supplements, but net weight gain (kg) and changes from baseline for weight, height, triceps and sub-scapular thickness Z-scores did not differ between the two supplements [mean (SD), RUTF vs ONS; weight gain (kg), 0.59 (0.30) vs 0.65 (0.42), p = 0.483; weight Z-score, 0.12 (0.09) vs 0.15 (0.13), p = 0.347; height Z-score, 0.04 (0.08) vs 0.04 (0.08), p = 0.908; triceps Z-score, 0.29 (0.24) vs 0.31 (0.23), p = 0.796; subscapular Z-score, 0.37 (0.29) vs 0.31 (0.25), p = 0.385]. Weight gain (0.6 kg) for both groups was lower than anticipated (2 kg). Post-supplementation, there was a tendency for weight and height Z-score to return to baseline.

CONCLUSIONS

RUTF and ONS are equivalently effective in improving nutritional outcomes in children 5 to 10 y at risk of malnutrition but the observed benefit is less than expected and not sustainable.

Barriers to access for severe acute malnutrition treatment services in Pakistan and Ethiopia: a comparative qualitative analysis

OBJECTIVE

To understand and compare the primary barriers households face when accessing treatment for cases of childhood severe acute malnutrition (SAM) in different cultural settings with different types of implementing agencies.

DESIGN

The study presents a comparative qualitative analysis of two SAM treatment services, selected to include: (i) one programme implemented by a non-governmental organization and one by a Ministry of Health; and (ii) programmes considered to be successful, defined as either coverage level achieved or extent of integration within government infrastructure. Results from individual interviews and group discussions were recorded and analysed for themes in barriers to access.

SETTING

Sindh Province, Pakistan; Tigray Region, Ethiopia.

SUBJECTS

Beneficiary communities and staff of SAM treatment services in two countries.

RESULTS

Common barriers were related to distance, high opportunity costs, knowledge of services, knowledge of malnutrition and child's refusal of ready-to-use foods. While community sensitization mechanisms were generally strong in these well-performing programmes, in remote areas with less programme exposure, beneficiaries experienced barriers to remaining in the programme until their children recovered.

CONCLUSIONS

Households experienced a number of barriers when accessing SAM treatment services. Integration of SAM treatment with other community-based interventions, as the UN recommends, can improve access to life-saving services. Efforts to integrate SAM treatment into national health systems should not neglect the community component of health systems and dedicated funding for the community component is needed to ensure access. Further research and policy efforts should investigate feasible mechanisms to effectively reduce barriers to access and ensure equitable service delivery.

Impact of lipid-based nutrient supplements and corn-soy blend on energy and nutrient intake among moderately underweight 8-18-month-old children participating in a clinical trial

Nutrition interventions have an effect on growth, energy and nutrient intake, and development, but there are mixed reports on the effect of supplementation of energy-dense foods on dietary intake. This substudy aimed at assessing the effect of supplementation with corn-soy blend (CSB) or lipid-based nutrient supplement (LNS) on energy and nutrient intake in moderately underweight children participating in a clinical trial. A total of 188 children aged 8-18 months participated and received daily either 284 kcal from CSB or 220 kcal from LNS and no supplements (control). An interactive 24-h recall method was used to estimate energy and nutrient intakes in the groups. Total mean energy intake was 548 kcal, 551 kcal and 692 kcal in the control, CSB and LNS groups, respectively (P = 0.011). The mean (95% confidence interval) intake of energy and protein were 144 (37-250; P < 0.001) and 46 (1.5-7.6; P < 0.001) larger, respectively, in the LNS group than among the controls. No significant differences were observed between the control and CSB groups. Energy intake from non-supplement foods was significantly lower in the CSB group compared with the control group, but not in the LNS group, suggesting a lower displacement of non-supplement foods with LNS. Both CSB and LNS supplementation resulted in higher intakes of calcium, iron, zinc and vitamin C compared with controls (all P ≤ 0.001). This study indicates that LNS might be superior to CSB to supplement underweight children as it results in higher energy intake, but this requires confirmation in other settings.
