Children with weight-for-age z-score (WAZ)

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

The interrelationship between wasting and stunting has been poorly investigated. We assessed the association between two indicators of linear growth, height-for-age Z-score (HAZ) change and occurrence of accelerated linear growth, and selected indicators of wasting and wasting reversal in 5,172 Cambodian children aged less than 24 months at enrolment in the ‘MyHealth’ study. The specific objectives were to evaluate the relationship between temporal changes in wasting and 1) change in HAZ and 2) episodes of accelerated linear growth. At enrolment, the stunting and wasting prevalence were 22.2 (21.0;23.3) % and 9.1 (8.1;10.1) %, respectively, and reached 41.4 (39.3;43.6) %, and 12.4 (11.5;13.3) % respectively, two years later. Between 14–19% of stunted children were also wasted throughout the whole study period. For each centimetre increase in Mid-Upper Arm Circumference (MUAC) from the previous assessment, the HAZ increased by 0.162 (0.150; 0.174) Z-score. We also observed a delayed positive association between the weight for height Z score (WHZ) unit increase and HAZ change of +0.10 to +0.22 units consistent with a positive relationship between linear growth and an increase in WHZ occurring with a lag of approximately three months. A similar positive correlation was observed for the occurrence of an episode of accelerated linear growth. These results show that interventions to prevent and treat wasting can contribute to stunting reduction and call for integrated wasting and stunting programming.

Each year in Niger, more than 40% of children under 5 years suffer from chronic malnutrition and more than 10% from acute malnutrition. The national nutrition rehabilitation protocol encourages the use of local foods. The objective of this work is to analyze the impact of supplementation inMoringa oleifera.We conducted a randomized double-blind clinical trial in 400 children with moderate acute malnutrition (MAM) aged 6 to 59 months admitted to outpatient nutritional recovery centers (CRENAM). The children were divided into two groups; one group received Ready-to-Use Supplemental Foods (RUSF) and dry leaf powder fromMoringaoleiferaand the other group received RUSF and placebo. We did not find any difference on average weight gain between the two groups or on mid-upper arm circumference and size. The median length of stay in CRENAM was 5 and 4 weeks forMoringaand placebo respectively, with no statistical difference (P=0.522). The cure rate was 82% (2.72) in theMoringagroup with a RR of 1.03 (0.94 to 1.13) slightly in favor ofMoringa. Renal and hepatic toxicity ofMoringawas not observed. From this clinical trial, it could be held thatMoringasupplementation, despite the presence of nutritional indices in favor ofMoringa, does not have a significant effect on the nutritional recovery of MAM children but thatMoringahas no renal or hepatic toxicity. Supplementation in subjects already on dietetic treatment, dose reduced to minimum and duration of supplementation seems to have played a role in this absence of effect ofMoringa.

Ready-to-use therapeutic food (RUTF) with adequate quality protein is used to treat children with oedematous and non-oedematous severe acute malnutrition (SAM). The plasma amino acid (AA) profile reflects the protein nutritional status; hence, its assessment during SAM treatment is useful in evaluating AA delivery from RUTFs. The objective was to evaluate the plasma AAs during the treatment of oedematous and non-oedematous SAM in community-based management of acute malnutrition (CMAM) using amino acid-enriched plant-based RUTFs with 10% milk (MSMS-RUTF) or without milk (FSMS-RUTF) compared to peanut milk RUTF (PM-RUTF). Plasma AA was measured in a non-blinded, 3-arm, parallel-group, simple randomized controlled trial conducted in Malawi. The RUTFs used for SAM were FSMS-RUTF, MSMS-RUTF or PM-RUTF. A non-inferiority hypothesis was tested to compare plasma AA levels from patients treated with FSMS-RUTF or MSMS-RUTF with those from patients treated with PM-RUTF at discharge. For both types of SAM, FSMS-RUTF and MSMS-RUTF treatments were non-inferior to the PM-RUTF treatment in restoration of the EAA and cystine except that for FSMS-RUTF, methionine and tryptophan partially satisfied the non-inferiority criteria in the oedematous group. Amino-acid-enriched milk-free plant-source-protein RUTF has the potential to restore all the EAA, but it is possible that enrichment with amino acids may require more methionine and tryptophan for oedematous children., SCOPUS: ar.j, info:eu-repo/semantics/published

Background Midupper arm circumference (MUAC) is used as an independent diagnostic tool to detect wasting in children aged 6–59 mo. However, little is known about the diagnostic performance of MUAC for detecting wasting among infants aged 1–6 mo. Objective The objective of this study was to evaluate the diagnostic performance of MUAC in detecting severe wasting in infants aged 1–6 mo. Methods We conducted a facility-based cross-sectional study among 467 hospitalized infants aged 1–6 mo in Ethiopia. Severe wasting was defined as having a weight for length z score (WLZ) below the cutoff value of −3 SDs from the median as per the WHO 2006 child growth standards. Receiver operating characteristic (ROC) analysis along with the calibration test was used to test the discriminatory performance of MUAC. Furthermore, we calculated the sensitivity, specificity, positive predictive value, and negative predictive value for the proposed optimal cutoffs. Results The median age, MUAC, and WLZ were 100 d (IQR: 69–145 d), 119 mm (IQR: 103–130 mm), and −1.27 (IQR: −2.66 to 0.34), respectively. The prevalence of severe and moderate wasting was n = 101 (21.6%) and n = 61 (13.0%), respectively. The MUAC area under the ROC curve accuracy level in identifying severe wasting was 0.86 (95% CI: 0.82, 0.89). The optimal MUAC cutoff of ≤112 mm yielded the highest Youden index of 0.61, with a sensitivity of 85.1% (95% CI: 76.7%, 91.4%) and a specificity of 76.0% (95% CI: 71.2%, 80.2%). Conclusions A MUAC cutoff of ≤112 mm performed well in detecting severe wasting among infants aged 1–6 mo. Further research is needed to evaluate the performance of MUAC for detecting wasting at community level and for predicting mortality among infants aged

Objective:To determine if a global mid-upper arm circumference (MUAC) cut-off can be established to classify underweight in adults (men and non-pregnant women).Design:We conducted an individual participant data meta-analysis (IPDMA) to explore the sensitivity (SENS) and specificity (SPEC) of various MUAC cut-offs for identifying underweight among adults (defined as BMI < 18·5 kg/m2). Measures of diagnostic accuracy were determined every 0·5 cm across MUAC values from 19·0 to 26·5 cm. A bivariate random effects model was used to jointly estimate SENS and SPEC while accounting for heterogeneity between studies. Various subgroup analyses were performed.Setting:Twenty datasets from Africa, South Asia, Southeast Asia, North America and South America were included.Participants:All eligible participants from the original datasets were included.Results:The total sample size was 13 835. Mean age was 32·6 years and 65 % of participants were female. Mean MUAC was 25·7 cm, and 28 % of all participants had low BMI (2). The area under the receiver operating characteristic curve for the pooled dataset was 0·91 (range across studies 0·61–0·98). Results showed that MUAC cut-offs in the range of ≤23·5 to ≤25·0 cm could serve as an appropriate screening indicator for underweight.Conclusions:MUAC is highly discriminatory in its ability to distinguish adults with BMI above and below 18·5 kg/m2. This IPDMA is the first step towards determining a global MUAC cut-off for adults. Validation studies are needed to determine whether the proposed MUAC cut-off of 24 cm is associated with poor functional outcomes.

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

Objective: To compare levels of immunity in children recovering from severe acute malnutrition (cases) against those of community controls (controls). Results: At baseline children recovering from severe acute malnutrition had lower, mid upper arm circumference (122 mm for cases and 135 mm for controls; p < 0.001), weight-for-height Z-score (- 1.0 for cases and - 0.5 for controls; p < 0.001), weight-for-age Z-score (- 2.8 for cases and - 1.1 for controls; p < 0.001) and height/length-for-age Z-score (- 3.6 for cases and - 1.4 for controls; p < 0.001), than controls. Age and gender matched community controls. At baseline, prevalence of a positive tuberculin skin test, assessed by cutaneous delayed-type hypersensitivity reaction skin test, was very low in both cases (3/93 = 3.2%) and controls (2/94 = 2.1%) and did not significantly increase at 6 months follow up (6/86 = 7.0% in cases and 3/84 = 3.4% in controls). The incidences of common childhood morbidities, namely fever, diarrhoea and cough, were 1.7-1.8 times higher among cases than controls. In conclusion, these results show that tuberculin skin test does not enable any conclusive statements regarding the immune status of patients following treatment for severe acute malnutrition. The increased incidence of infection in cases compared to controls suggests persistence of lower resistance to infection even after anthropometric recovery is achieved., SCOPUS: ar.j, info:eu-repo/semantics/published

Anemia is a worldwide public health concern especially in preschool children in developing countries and iron deficiency (ID) is generally assumed to cause at least 50% of the cases. However, data on this contribution are scarce. To close this gap, we determined in 2013 the contribution of ID in the etiology of anemia and measured others factors associated to noniron deficiency anemia (NIDA) in 900 preschool children randomly selected during a two-stage cluster nutritional survey in the Miti-Murhesa health zone, in eastern Democratic Republic of the Congo. In these children, we collected sociodemographic, clinical, and biological parameters and determined the nutritional status according to the World Health Organization 2006 standards. Anemia was defined as altitude-adjusted hemoglobin < 110 g/L and ID was defined as serum ferritin < 12 μg/L or < 30 μg/L in the absence or presence of inflammation, respectively. Median (interquartile range) age was 29.4 (12–45) months. The prevalence of anemia was 46.6% (391/838) among whom only 16.5% (62/377) had ID. Among children without signs of inflammation, only 4.4% (11/251) met the ferritin-based (unadjusted) definition of ID. Logistic regression analysis identified ID, history of fever during the last 2 weeks and mid-upper arm circumference < 125 mm as the only independent factors associated to anemia. In conclusion, anemia is a severe public health problem in the Miti-Murhesa health zone, but NIDA is mostly predominant and needs to be further studied. Control of infections and prevention of acute undernutrition (wasting) are some of appropriate interventions to reduce the burden anemia in this region.

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

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

Background: Wasting and underweight in infancy is an increasingly recognised problem but consensus on optimum assessment is lacking. In particular, there is uncertainty on how to interpret anthropometry among low birth weight (LBW) infants who may be growing normally. This research aimed to determine growth of infants from birth to two months (around age of vaccination) and the mortality risk of underweight LBW infants compared to normal birth weight (NBW) infants at two and six months age. Methods: A secondary analysis of a birth cohort of 1103 infants in Burkina Faso was conducted. Anthropometry was performed monthly from 0 to 12 months. We assessed associations with mortality using Cox proportional hazards models and assessed discriminatory values using area under receiver operating characteristics curves. Results: Eighty-six (7.8%) children died by age one year, 26/86 (30%) and 51/86 (59%) within two and six months, respectively. At age two months, weight gain since birth did not better discriminate mortality risk than current weight-for-age (P=0.72) or mid-upper arm circumference (P=0.21). In total, 227 (21%) LBW infants had increased risk of mortality: adjusted hazards ratio (aHR) 3.30 (95%CI 2.09 to 4.90). Among infants who were underweight at two and six months, LBW infants (64% and 49%, respectively) were not at reduced risk of death compared to NBW infants (aHR 2.63 (95%CI 0.76 to 9.15) and 2.43 (95%CI 0.74 to 7.98), respectively). Conclusion: Assessing weight gain since birth does not offer advantages over immediate anthropometry for discriminating mortality risk. LBW infants who are later identified as underweight require care to help prevent mortality.

Background Ready-to-use therapeutic food (RUTF) is used to treat children suffering from severe acute malnutrition (SAM). Standard RUTF uses milk as the primary protein source, which makes the product expensive, and given the high worldwide SAM burden, having a less expensive effective alternative is a public health priority. Objective The objective of this study was to evaluate whether newly developed amino acid-enriched milk-free RUTF (FSMS-RUTF) or amino acid-enriched low-milk RUTF (MSMS-RUTF) treatment could replenish plasma amino acids to levels comparable to those following standard peanut-milk RUTF (PM-RUTF) treatment and to improve understanding of the effects of treatment on anthropometric measurements. A secondary analysis was performed to test the noninferiority hypothesis of plasma essential amino acid (EAA) levels. Methods Plasma EAA levels were measured in a nonblinded, 3-arm, parallel-group simple randomized controlled trial conducted in Malawi to examine the efficacy of FSMS-RUTF, MSMSRUTF and PM-RUTF in the treatment of SAM in 2 groups of children aged 6-23 and 24-59 months (mo). Sample size calculations were performed based on the previous our study. A noninferiority margin was set at -25% of the PM-RUTF arm at discharge. Results The relative values of the differences (95% CI) in plasma EAA levels between PM-RUTF treatment and FSMS-RUTF and MSMS-RUTF treatments at discharge were -7.9% (-18.6, 2.8) and 9.8% (0.2, 19.5), respectively, in children aged 6-23 mo, while in those aged 24-59 mo, the difference values were 17.8% (1.6, 34.1) and 13.6% (-2.8, 29.9), respectively. Conclusion At discharge, the plasma EAA concentrations in 6-59-mo-old SAM children treated with FSMS-RUTF and MSMS-RUTF were not less than those of children treated with PM-RUTF. These findings indicate that treatment with either of the 3 RUTFs was associated with adequate protein synthesis and that all the formulations provided sufficient functional metabolites of plasma amino acids to support nutritional recovery from SAM., SCOPUS: ar.j, info:eu-repo/semantics/published

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

Background: Development of more cost-effective ready-to-use therapeutic food (RUTF) is a global public health priority. To date, previous lower-cost recipes have been less effective than the standard peanut and milk (PM)-based RUTF, particularly in children aged

Background Children with moderate acute malnutrition (MAM) have an increased risk of mortality, infections and impaired physical and cognitive development compared to well-nourished children. In parts of Ethiopia not considered chronically food insecure there are no supplementary feeding programmes (SFPs) for treating MAM. The short-term outcomes of children who have MAM in such areas are not currently described, and there remains an urgent need for evidence-based policy recommendations. Methods We defined MAM as mid-upper arm circumference (MUAC) of ≥11.0cm and, SCOPUS: ar.j, info:eu-repo/semantics/published

Efficacy and cost of nutritional supplements are critical in addressing malnutrition. Use of cheaper and locally available ingredients in manufacturing ready-to-use foods (RUF) can potentially reduce cost and increase access to supplements in resource-poor settings. Soy protein concentrate (SPC) is a cheaper source of protein and can potentially replace the more expensive milk powder in RUF. However, SPC contains phytic acid (PA) which inhibits mineral bioavailability. PA may be degraded by the enzyme phytase. This study aimed to determine the effect of replacing skim milk powder (MP) with SPC and of added phytase on bioavailability of iron and zinc in soybean-maize-sorghum RUF. RUF samples were made using either SPC or MP. Phytase was added to food samples with either low ( 50%) moisture prior to estimation of bioavailability of iron and zinc by in vitro dialysability. Compared to samples with MP, SPC-based foods had significantly higher content of PA (0.84 g/100 g vs. 0.57 g/100 g; p

The effectiveness of the community based therapeutic care (CTC) in treating severe acute malnutrition (SAM) has been demonstrated. However, there is still resistance from some policy makers and donors to invest into this cost-effective intervention. The mortality rate ratio (MRR) calculated by dividing the observed deaths after discharge by expected deaths was used to compare survival of 1,670 children discharged from the Dowa CTC from August 2002 to May 2005 and that of other cohorts reporting on long term survival of children after treatment of SAM retrieved from literature. A MMR of 1.1 (0.9 to 1.4) was observed for the Dowa CTC cohort while the MMR of 2.7 (1.3 to 4.9), 5.5 (3.9 to 7.6) and 20.0 (11.0 to 33.4) were observed for studies retrieved from the literature. Data showed that the survival of children who defaulted was worse than that of those who were discharged cured, and that of children treated at home after stabilisation or directly was better than those treated as inpatient until exit from the programme. The study outlines the need of using MMR when reporting on long term survival after SAM treatment and suggests that CTC should be included in the package of interventions with high potential for accelerating the progress towards reaching Millennium Developmental Goal four. Key words: Severe acute malnutrition, children, long term, survival, mortality ratio.

BACKGROUND: Evidence of the effectiveness of lipid-based ready-to-use complementary foods (RUCF) at improving linear growth among infants aged 6-12 mo is scarce and further work is warranted. OBJECTIVE: The objective was to assess the effectiveness of a fortified soybean-maize-sorghum RUCF paste compared with a fortified corn soy blend (UNIMIX) porridge on the prevalence of underweight and stunting among infants in South Kivu Province Democratic Republic of Congo. DESIGN: Infants were randomly assigned at 6 mo of age to receive either RUCF (n = 691) or UNIMIX (n = 692) for 6 mo. In addition to admission and monthly anthropometric measurements hemoglobin triglyceride and cholesterol were measured at enrollment and at the end of the study. RESULTS: No significant differences in the prevalence of stunting (RUCF: 48.6%; UNIMIX: 46.4%; P = 0.31) the prevalence of underweight (RUCF: 20.4%; UNIMIX: 18.2%; P = 0.42) or weight gain (RUCF: 1.2 +/- 0.7 kg; UNIMIX: 1.3 +/- 0.7 kg; P = 0.08) were found. A small but statistically significant difference in length gain (RUCF: 5.2 +/- 2.0; UNIMIX: 5.4 +/- 2.0; P = 0.03) was found. No significant differences in the concentrations of hemoglobin serum triglyceride and serum cholesterol were found between the 2 groups. CONCLUSION: No significant differences were found between the RUCF and UNIMIX in the reduction of the prevalence of stunting and underweight at 12 mo of age among rural Congolese infants. This trial was registered at controlled-trials.com as ISRCTN20267635.

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

BACKGROUND: The cost of current standard ready-to-use therapeutic food (RUTF) is among the major obstacles to scaling up community-based management of acute malnutrition (CMAM), an important child survival strategy. Identifying a cheaper alternative is a global public health priority. OBJECTIVE: We sought to compare the efficacy of soya-maize-sorghum RUTF (SMS-RUTF) with that of standard peanut paste-based RUTF (P-RUTF). DESIGN: We used a nonblinded, parallel-group, simple randomized controlled trial along with a day care approach that enrolled 2 groups of children aged 6-23 and 24-59 mo, respectively, with severe acute malnutrition (SAM). RESULTS: Intention-to-treat (ITT) and per-protocol (PP) analyses showed noninferiority of SMS-RUTF compared with P-RUTF for the recovery rate [ITT: Δ = -2.0% (95% CI: -7.6%, 3.6%); PP: -1.9% (95% CI: -5.3%, 1.4%)], weight gain [Δ = -0.7 g · kg(-1)· d(-1)(95% CI: -1.3, 0.0 g · kg(-1)· d(-1))], and length of stay [Δ = 2.0 d (95% CI: -1.7, 5.8 d)] in children ≥24 mo of age. In children ≤23 mo of age, the recovery rate of SMS-RUTF was inferior to that of P-RUTF [ITT: Δ = -20.8% (95% CI: -29.9%, -11.7%); PP: -17.2% (95% CI: -25.6%, -8.7%)]. Treatment with SMS-RUTF resulted in a greater increase in hemoglobin [0.670 g/dL (95% CI: 0.420, 0.921 g/dL);P< 0.001]. Treatment with both RUTFs resulted in the replenishment of all of the amino acids tested except for methionine. There were no differences at discharge between RUTF groups in fat mass [Δ = 0.3 kg (95% CI: -0.6, 1.6 kg);P= 0.341] or fat mass index [Δ = 0.4 kg/m(2)(95% CI: -0.3, 1.1 kg/m(2));P= 0.262]. By contrast, comparisons of fat-free mass indicated lower concentrations than the community controls after treatment with either of the 2 RUTFs [Δ = -1.3 kg (95% CI: -2.4, -0.1 kg) andP= 0.034 for comparison between community controls and the SMS-RUTF group; Δ = -1.8 kg (95% CI: -2.9, -0.6 kg) andP= 0.003 for comparison between community controls and the P-RUTF group]. CONCLUSION: SMS-RUTF can be used to treat SAM in children aged ≥24 mo to reduce the costs of CMAM programs. More research is required to optimize SMS-RUTF for younger children. This trial was registered in the Pan African Clinical Trial Registry as PACTR201303000475166.

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