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

Nutritional deficiencies in the developing world: current status and opportunities for intervention

Several contributory factors such as poverty, lack of purchasing power, household food insecurity, and limited general knowledge about appropriate nutritional practices increase the risk of undernutrition in developing countries. The synergistic interaction between inadequate dietary intake and disease burden leads to a vicious cycle that accounts for much of the high morbidity and mortality in these countries. Three groups of underlying factors contribute to inadequate dietary intake and infectious disease: inadequate maternal and child care, household food insecurity, and poor health services in an unhealthy environment.

A ready-to-use therapeutic food containing 10% milk is less effective than one with 25% milk in the treatment of severely malnourished children

Standard therapy for severe acute malnutrition (SAM) is home-based therapy with ready-to-use therapeutic food (RUTF) containing 25% milk. In an effort to lower the cost of RUTF and increase availability, some have suggested that a portion of milk be replaced with soy. This trial was designed to determine whether treating children with SAM with 10% milk RUTF containing soy would result in a similar recovery rate compared with the 25% milk RUTF. This was a randomized, double-blind, controlled, clinical, quasi-effectiveness trial of isoenergetic amounts of 2 locally produced RUTF to treat SAM in Malawi among children aged 6-59 mo. A total of 1874 children were enrolled. Children were assessed every fortnight and participated in the study until they clinically recovered or received 8 wk of treatment. The primary outcome was recovery (weight-for-height Z score > -2 and no edema). Secondary outcomes were rates of weight and height gain. Survival analysis was used to compare the recovery rates. Recovery among children receiving 25% milk RUTF was greater than children receiving 10% milk RUTF, 64% compared with 57% after 4 wk, and 84% compared with 81% after 8 wk (P < 0.001). Children receiving 25% milk RUTF also had higher rates of weight and height gain compared with children receiving 10% milk RUTF. Treating children with SAM with 10% milk RUTF is less effective compared with treatment with the standard 25% milk RUTF. These findings also emphasize that clinical evidence should be examined before recommending any changes to the formulation of RUTF.

A lipid-based nutrient supplement but not corn-soy blend modestly increases weight gain among 6- to 18-month-old moderately underweight children in rural Malawi

Although widely used, there is little information concerning the efficacy of corn-soy blend (CSB) supplementation in the treatment of moderate underweight in African children. Lipid-based nutrient supplements (LNS), which have proven to be beneficial treatment for severely wasted children, could offer benefits to less severely affected individuals. We conducted a clinical randomized trial to determine whether LNS or CSB supplementation improves weight gain of moderately underweight children. A total of 182 underweight [weight-for-age Z-score (WAZ) < -2] 6- to 15-mo-old children were randomized to receive for 12 wk a ration of 43 g/d LNS or 71 g/d CSB, providing 1189 and 921 kJ, respectively, or no supplementation (control). The primary outcome was weight change; secondary outcomes included changes in anthropometric indices, hemoglobin levels, and morbidity. The body weight increases (mean ± SD) did not differ and were 620 ± 470, 510 ± 350, and 470 ± 350 g in the LNS, CSB, and control groups, respectively (P = 0.11). Compared with controls, infants and children in the LNS group gained more weight [mean (95% CI) = 150 g (0-300 g); P = 0.05] and had a greater increase in WAZ [0.33 (-0.02-0.65); P = 0.04]. Weight and WAZ changes did not differ between the control and CSB groups. In exploratory stratified analysis, the weight increase was higher in the LNS group compared with the control group among those with lower initial WAZ [250 g (60-430 g; P = 0.01]. Supplementation with LNS but not CSB modestly increases weight gain among moderately underweight children and the effect appears most pronounced among those with a lower initial WAZ.

Reducing wasting in young children with preventive supplementation: a cohort study in Niger

OBJECTIVE

To compare the incidence of wasting, stunting, and mortality among children aged 6 to 36 months who are receiving preventive supplementation with either ready-to-use supplementary foods (RUSFs) or ready-to-use therapeutic foods (RUTFs).

SUBJECTS AND METHODS

Children aged 6 to 36 months in 12 villages of Maradi, Niger, (n = 1645) received a monthly distribution of RUSFs (247 kcal [3 spoons] per day) for 6 months or RUTFs (500-kcal sachet per day) for 4 months. We compared the incidence of wasting, stunting, and mortality among children who received preventive supplementation with RUSFs versus RUTFs.

RESULTS

The effectiveness of RUSF supplementation depended on receipt of a previous preventive intervention. In villages in which a preventive supplementation program was previously implemented, the RUSF strategy was associated with a 46% (95% confidence interval [CI]: 6%-69%) and 59% (95% CI: 17%-80%) reduction in wasting and severe wasting, respectively. In contrast, in villages in which the previous intervention was not implemented, we found no difference in the incidence of wasting or severe wasting according to type of supplementation. Compared with the RUTF strategy, the RUSF strategy was associated with a 19% (95% CI: 0%-34%) reduction in stunting overall.

CONCLUSION

We found that the relative performance of a 6-month RUSF supplementation strategy versus a 4-month RUTF strategy varied with receipt of a previous nutritional intervention. Contextual factors will continue to be important in determining the dose and duration of supplementation that will be most effective, acceptable, and sustainable for a given setting.

Feeding patterns and behaviors during home supplementation of underweight Malawian children with lipid-based nutrient supplements or corn-soy blend

The way caregivers use supplementary food for undernourished children and integrate it into feeding patterns may influence the benefits achieved by supplementation. We studied feeding patterns and behaviors in 170 underweight 6-17-month-olds who received either lipid-based nutrient supplements (LNS) (n=85) or corn-soy blend (CSB) (n=85) during a 12-week intervention trial in southern Malawi. Observational data were collected during one 11h home visit per participant. Differences were assessed by study group and by mode of serving LNS. Associations between selected caregiver behaviors and child growth were also tested. We found no difference between the CSB and LNS groups in mean number of feeding episodes per day or mean daily feeding time. Caregivers fed the child with a spoon, washed their hands before feeding, and there were leftovers significantly more often in the CSB than LNS group and when LNS mixed with porridge and plain LNS were compared. This suggests that differences between the groups were linked to the mode of serving LNS. Presence of leftovers was negatively associated with change in child's WAZ. Programs promoting LNS in Malawi should consider behaviors related to mode of serving and provide advice to caregivers in order to minimize leftovers during supplement use.

Acute malnutrition is common in Malawian patients with a Wilms tumour: A role for peanut butter

BACKGROUND

Children with cancer in resource limited countries are often malnourished at diagnosis. Acute malnutrition is associated with more infectious complications and an increased risk of morbidity and mortality in major surgery.

METHODS

All new patients with the clinical diagnosis of a Wilms tumour admitted in the Queen Elizabeth Central Hospital, Blantyre, Malawi from January 2007 until June 2008 were included. We documented anthropometric parameters, tumour size and serum levels of micronutrients at diagnosis. Corrected weight (body weight - tumour weight) was repeated after 4 weeks of preoperative chemotherapy. During therapy oral feeds were encouraged and a locally made ready to use therapeutic peanut butter-based food (chiponde) supplied.

RESULTS

A high rate of acute malnutrition was found in patients with Wilms tumour at diagnosis (45-55%), much higher than in community controls (11%). Patients (40%) and community controls (37%) had a similar, high rate of stunting (low height for age), a sign of chronic malnutrition. Tumour size at diagnosis and the degree of acute malnutrition at diagnosis was correlated; patients with a larger tumour had more severe acute malnutrition (r = -0.88, P < 0.01). With a supply of chiponde, 7 of 18 patients had a >5% increase in corrected weight during preoperative chemotherapy. Patients with a more positive nutritional course had a better tumour response to chemotherapy (r = 0.52, P < 0.05). Surprisingly, few micronutrient deficiencies were found, except for low serum levels of vitamin A (44% of patients).

CONCLUSION

Acute malnutrition, superimposed on chronic malnutrition, is common in patients with Wilms tumour in Malawi. Earlier presentation needs to be encouraged. Chiponde, a peanut butter based ready-to-use-therapeutic-food, is an attractive means of nutritional support which needs further study.

Management of children with acute malnutrition in resource-poor settings

Approximately 11% of children worldwide suffer from moderate or severe acute malnutrition, which is defined as low weight for height or mid-upper arm circumference with respect to international standards, or the presence of bipedal edema. These children have a considerably increased risk of dying. Experience from the past two decades indicates that children with uncomplicated moderate or severe acute malnutrition can be managed successfully as outpatients, by use of appropriate treatment of infections and either lipid-based, ready-to-use therapeutic foods or appropriately formulated home diets, along with psychosocial care. Children's caregivers prefer community-based treatment, which is also less costly than inpatient care. Children with severe acute malnutrition and life-threatening complications require short-term inpatient care for treatment of infections, fluid and electrolyte imbalances, and metabolic abnormalities. Initial dietary management relies on low-lactose, milk-based, liquid formulas but semi-solid or solid foods can be started as soon as appetite permits, after which children can be referred for ambulatory treatment. National programs for the community-based management of acute malnutrition (CMAM) provide periodic anthropometric and clinical screening of young children, and referral of those who meet established criteria. This Review describes the main components of the treatment of young children with acute malnutrition in resource poor settings and some recent advances in CMAM programs.

International child health: state of the art

Many published articles and policies describe what should be state of the art in global child health, and there are dozens of large initiatives aimed at implementing these policies. We have knowledge of what should work, yet struggle to effectively implement that knowledge and improve child health outcomes in resource-poor settings, even at the most basic level of ensuring sufficient food and clean water for the world's children. This article highlights many smaller programs that are operational in the field, demonstrating excellence in global child health efforts, and may approach state of the art in actual implementation. The examples include a grass roots primary health care program, a home-based neonatal care program, kangaroo mother care, ready-to-use therapeutic food (RUTF), a vitamin A program, point-of-use water purification, disasters and children, a pain management program, and a developmental disabilities program. This article also discusses the importance of strengthening human resources for health by, for example, training child health professionals in low resource countries. These programs show what can be done and could be replicated in other communities to improve child health, given a few committed individuals and modest resources. Ultimately, truly state of the art health care for children must be defined locally and championed by each state or nation. Nevertheless, there are overarching components and supports that are the responsibility of the global community, particularly those needed to assure that the basic human rights of children, including health, are met throughout the world.

Macronutrient supplementation for malnourished HIV-infected adults: a review of the evidence in resource-adequate and resource-constrained settings

Access to antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection has expanded rapidly throughout sub-Saharan Africa, but malnutrition and food insecurity have emerged as major barriers to the success of ART programs. Protein-calorie malnutrition (a common form of malnutrition in the region) hastens HIV disease progression, and food insecurity is a barrier to medication adherence. Analyses of patient outcomes have identified a low body mass index after the start of ART as an independent predictor of early mortality, but the causes of a low body mass index are multifactorial (eg, normal anthropometric variation, chronic inadequate food intake, and/or wasting associated with HIV infection and other infectious diseases). Although there is much information on population-level humanitarian food assistance, few data exist to measure the effectiveness of macronutrient supplementation or to identify individuals most likely to benefit. In this report, we review the current evidence supporting macronutrient supplementation for HIV-infected adults, we report on clinical trials in resource-adequate and resource-constrained settings, and we highlight priority areas for future research.

Ethical challenges in conducting research in humanitarian crisis situations

Research is vital to accurately describe phenomena in humanitarian emergency situations and to evaluate the effectiveness and appropriateness of interventions. Although the ethical principles of justice, beneficence and respect for autonomy respect for persons should be upheld in research, their application in emergency situations may differ from non-emergency situations. Just like in non-emergency situations, research in emergency situations should be conducted in the best interest of the victims or future victims. The research should not unnecessarily expose human subjects and the researcher to careless harm, and should be of adequate scientific rigor. Victims of emergency situations are vulnerable populations that need special protection from exploitation. Technical competency to conduct research in emergency situations should include the ability to conduct a fair risk-benefit assessment in order to come up with a risk management plan, and being culturally sensitive to the needs of the victims of the humanitarian crisis. In emergency situations, the roles of Institutional Review Boards (IRBs) may have to be modified without compromising the ethical standards that health researchers have globally attempted to achieve.

Malawian mothers' attitudes towards the use of two supplementary foods for moderately malnourished children

The efficacy of lipid-based nutrient supplements (LNS) versus corn-soy blend (CSB) in promoting the growth of moderately malnourished children is currently being tested, but information about maternal attitudes towards the two supplements is lacking. This research studied 504 Malawian mothers' attitudes about LNS and CSB through exit interviews completed at the end of three 12-week clinical trials and compared differences between the groups. Exploratory analyses of factors associated with withholding of supplements during fever, diarrhea, and cough were performed using logistic regression. Mothers generally had similar, positive attitudes towards LNS and CSB. Both supplements were said to be highly acceptable, children learned to eat them within two weeks, and mothers were willing to use them again. Mothers in the LNS group were reportedly more likely to withhold supplements from their children during cough, due to its sweetness, and were willing to pay more for a one-week supply of supplement than mothers in the CSB group. Maternal literacy was negatively and child's weight-for-height z-score was positively associated with withholding of supplements during illness. Our results indicate that the sweetness in LNS should be reduced, and programs using supplements in Malawi could include advice on appropriate feeding of supplements during illness.

Supplementary feeding with fortified spread among moderately underweight 6-18-month-old rural Malawian children

We aimed to analyse growth and recovery from undernutrition among moderately underweight ambulatory children receiving micronutrient-fortified maize-soy flour (Likuni Phala, LP) or ready-to-use fortified spread (FS) supplementary diet. One hundred and seventy-six 6-18-month-old individuals were randomized to receive 500 g LP or 350 g FS weekly for 12 weeks. Baseline and end of intervention measurements were used to calculate anthropometric gains and recovery from underweight, wasting and stunting. Mean weight-for-age increased by 0.22 (95% CI 0.07-0.37) and 0.28 (0.18-0.40) Z-score units in the LP and FS groups respectively. Comparable increase for mean weight-for-length was 0.39 (0.20-0.57) and 0.52 (0.38-0.65) Z-score units. Recovery from underweight and wasting was 20% and 93% in LP group and 16% and 75% in FS group. Few individuals recovered from stunting and mean length-for-age was not markedly changed. There were no statistically significant differences between the outcomes in the two intervention groups. In a poor food-security setting, underweight infants and children receiving supplementary feeding for 12 weeks with ready-to-use FS or maize-soy flour porridge show similar recovery from moderate wasting and underweight. Neither intervention, if limited to a 12-week duration, appears to have significant impact on the process of linear growth or stunting.

Supplementary feeding with fortified spreads results in higher recovery rates than with a corn/soy blend in moderately wasted children

Moderate childhood wasting is defined as having a weight-for-height Z-score (WHZ) < -2, but > or = -3. These children are typically given fortified corn/soy blended flour (CSB), but this intervention has shown limited effectiveness. Fortified spreads (FS) can be used as supplementary foods instead; they are energy-dense, lipid-based pastes with added powdered micronutrients. In this randomized clinical effectiveness trial, the recovery rates were compared among children with moderate wasting who received either milk/peanut FS, soy/peanut FS, or CSB. Children received isoenergetic quantities of food, 314 kJ x kg(-1) x d(-1), for up to 8 wk with biweekly follow-up. The primary outcome was recovery, defined as having a WHZ > -2. Time-event analysis was used to compare the recovery rate. A total of 1362 children were enrolled in the study. Children receiving soy/peanut FS had a similar recovery rate to those receiving milk/peanut FS and children in either FS group were more likely to recover than those receiving CSB (80% in both FS groups vs. 72% in the CSB group; P < 0.01). The rate of weight gain in the first 2 wk was greater among children receiving milk/peanut FS (2.6 g x kg(-1) x d(-1), n = 465) or children receiving soy/peanut FS (2.4 g x kg(-1) x d(-1), n = 450) than among children receiving CSB (2.0 g x kg(-1) x d(-1), n = 447; P < 0.05). Rates of length gain did not differ among the 3 groups. A total of 8% of children in each feeding group developed edema, indicative of severe malnutrition, while receiving supplemental feeding. We conclude that FS are superior supplementary foods to CSB for moderately wasted Malawian children.

Safety of rapid intravenous rehydration and comparative efficacy of 3 oral rehydration solutions in the treatment of severely malnourished children with dehydrating cholera

OBJECTIVES

Assess the safety of rapid intravenous rehydration of severely malnourished children and compare the efficacy of 3 formulations of oral rehydration salts solutions.

PATIENTS AND METHODS

A group of 175 severely malnourished children of either sex (weight/length <70% of National Center for Health Statistics median), ages 6 to 36 months with cholera, were randomly assigned to receive 1 of 3 oral rehydration solutions (ORSs): glucose-ORS (n=58), glucose-ORS plus 50 g/L of amylase-resistant starch (n=59), or rice-ORS (n=58). Severely dehydrated children at enrollment were administered 100 mL/kg of an intravenous solution for 4 to 6 hours before randomisation, and those with some dehydration were randomised on enrollment. The electrolytes of the 3 ORSs were identical. In acute and convalescence phases, treatment was similar other than the nature of the ORSs.

RESULTS

Intravenous fluid (mean) administered to 149 study children was 103 mL/kg (95% confidence interval [CI] 96-109), and all were rehydrated within 6 hours. None of them developed overhydration or heart failure. During the first 24 hours, stool output (31%; 95% CI 14%-42%; P=0.004) and the ORS intake (26%; 95% CI 12%-37%; P=0.002) of children receiving rice-ORS were significantly less compared with children receiving glucose-ORS. The mean duration of diarrhoea in all children (66 hours; 95% CI 62-71), and time to attain 80% of median weight/length (7.15+/-2.81 days) were not different.

CONCLUSIONS

Dehydration in severely malnourished children can safely be corrected within 6 hours. All study ORSs were equally efficient in correcting dehydration. Rice-ORS significantly reduced the stool output and ORS intake, confirming previous reports.

Effect of preventive supplementation with ready-to-use therapeutic food on the nutritional status, mortality, and morbidity of children aged 6 to 60 months in Niger: a cluster randomized trial

CONTEXT

Ready-to-use therapeutic foods (RUTFs) are an important component of effective outpatient treatment of severe wasting. However, their effectiveness in the population-based prevention of moderate and severe wasting has not been evaluated.

OBJECTIVE

To evaluate the effect of a 3-month distribution of RUTF on the nutritional status, mortality, and morbidity of children aged 6 to 60 months in Niger.

DESIGN, SETTING, AND PARTICIPANTS

A cluster randomized trial of 12 villages in Maradi, Niger. Six villages were randomized to intervention and 6 to no intervention. All children in the study villages aged 6 to 60 months were eligible for recruitment.

INTERVENTION

Children with weight-for-height 80% or more of the National Center for Health Statistics reference median in the 6 intervention villages received a monthly distribution of 1 packet per day of RUTF (92 g [500 kcal/d]) from August to October 2006. Children in the 6 nonintervention villages received no preventive supplementation. Active surveillance for conditions requiring medical or nutritional treatment was conducted monthly in all 12 study villages from August 2006 to March 2007.

MAIN OUTCOME MEASURES

Changes in weight-for-height z score (WHZ) according to the World Health Organization Child Growth Standards and incidence of wasting (WHZ <-2) over 8 months of follow-up.

RESULTS

The number of children with height and weight measurements in August, October, December, and February was 3166, 3110, 2936, and 3026, respectively. The WHZ difference between the intervention and nonintervention groups was -0.10 z (95% confidence interval [CI], -0.23 to 0.03) at baseline and 0.12 z (95% CI, 0.02 to 0.21) after 8 months of follow-up. The adjusted effect of the intervention on WHZ from baseline to the end of follow-up was thus 0.22 z (95% CI, 0.13 to 0.30). The absolute rate of wasting and severe wasting, respectively, was 0.17 events per child-year (140 events/841 child-years) and 0.03 events per child-year (29 events/943 child-years) in the intervention villages, compared with 0.26 events per child-year (233 events/895 child-years) and 0.07 events per child-year (71 events/1029 child-years) in the nonintervention villages. The intervention thus resulted in a 36% (95% CI, 17% to 50%; P < .001) reduction in the incidence of wasting and a 58% (95% CI, 43% to 68%; P < .001) reduction in the incidence of severe wasting. There was no reduction in mortality, with a mortality rate of 0.007 deaths per child-year (7 deaths/986 child-years) in the intervention villages and 0.016 deaths per child-year (18 deaths/1099 child-years) in the nonintervention villages (adjusted hazard ratio, 0.51; 95% CI, 0.25 to 1.05).

CONCLUSION

Short-term supplementation of nonmalnourished children with RUTF reduced the decline in WHZ and the incidence of wasting and severe wasting over 8 months.

Postintervention growth of Malawian children who received 12-mo dietary complementation with a lipid-based nutrient supplement or maize-soy flour

BACKGROUND

Therapeutic feeding with micronutrient-fortified lipid-based nutrient supplements (LNSs) has proven useful in the rehabilitation of severely malnourished children. We recently reported that complementary feeding of 6-18-mo-old infants with an LNS known as FS50 was associated with improved linear growth and a reduction in the incidence of severe stunting during the supplementation period.

OBJECTIVE

Our objective was to assess whether a reduction in stunting seen with 12-mo LNS supplementation was sustained over a subsequent 2-y nonintervention period.

DESIGN

One hundred eighty-two 6-mo-old healthy rural Malawian infants were randomly assigned to receive daily supplementation for 12 mo with 71 g of maize-soy flour [likuni phala (LP); control group, 282 kcal] or either 50 g of FS50 (264 kcal; main intervention group), or 25 g of FS25 (130 kcal). Main outcome measures were incidence of severe stunting and mean z score changes in weight-for-age, length-for-age, and weight-for-length during a 36-mo follow-up period.

RESULTS

The cumulative 36-mo incidence of severe stunting was 19.6% in LP, 3.6% in FS50, and 10.3% in FS25 groups (P = 0.03). Mean weight-for-age changes were -1.09, -0.76, and -1.22 (P = 0.04); mean length-for-age changes were -0.47, -0.37, and -0.71 (P = 0.10); and mean weight-for-length changes were -1.52, -1.18, and -1.48 (P = 0.27). All differences were more marked among individuals with baseline length-for-age below the median. Differences in length developed during the intervention at age 10-18 mo, whereas weight differences continued to increase after the intervention.

CONCLUSIONS

Twelve-month-long complementary feeding with 50 g/d FS50 is likely to have a positive and sustained impact on the incidence of severe stunting in rural Malawi. Half-dose intervention may not have the same effect. This trial was registered at (clinicaltrials.gov) as NCT00131209.

Improving the management of severe acute malnutrition in an area of high HIV prevalence

AIM

To assess the clinical outcomes of a combined approach to the treatment of severe acute malnutrition in an area of high HIV prevalence using: (i) an initial inpatient phase, based on WHO guidelines and (ii) an outpatient recovery phase using ready-to-use therapeutic food.

METHODS

An operational prospective cohort study implemented in a referral hospital in Southern Malawi between May 2003 and 2004. Patient outcomes were compared with international standards and with audits carried out during the year preceding the study.

RESULTS

Inpatient mortality was 18% compared to 29% the previous year. Programme recovery rate was 58.1% compared to 45% the previous year. The overall programme mortality rate was 25.7%. Of the total known HIV seropositive children, 49.5% died.

CONCLUSIONS

Inpatient mortality and cure rates improved compared to pre-study data but the overall mortality rate did not meet international standards. Additional interventions will be needed if these standards are to be achieved.

Complementary feeding with fortified spread and incidence of severe stunting in 6- to 18-month-old rural Malawians

OBJECTIVE

To compare growth and incidence of malnutrition in infants receiving long-term dietary supplementation with ready-to-use fortified spread (FS) or micronutrient-fortified maize-soy flour (likuni phala [LP]).

DESIGN

Randomized, controlled, single-blind trial.

SETTING

Rural Malawi.

PARTICIPANTS

A total of 182 six-month-old infants.

INTERVENTION

Participants were randomized to receive 1 year of daily supplementation with 71 g of LP (282 kcal), 50 g of FS (FS50) (256 kcal), or 25 g of FS (FS25) (130 [corrected] kcal).

OUTCOME MEASURES

Weight and length gains and the incidences of severe stunting, underweight, and wasting.

RESULTS

Mean weight and length gains in the LP, FS50, and FS25 groups were 2.37, 2.47, and 2.37 kg (P = .66) and 12.7, 13.5, and 13.2 cm (P = .23), respectively. In the same groups, the cumulative 12-month incidence of severe stunting was 13.3%, 0.0%, and 3.5% (P = .01), of severe underweight was 15.0%, 22.5%, and 16.9% (P = .71), and of severe wasting was 1.8%, 1.9%, and 1.8% (P > .99). Compared with LP-supplemented infants, those given FS50 gained a mean of 100 g more weight and 0.8 cm more length. There was a significant interaction between baseline length and intervention (P = .04); in children with below-median length at enrollment, those given FS50 gained a mean of 1.9 cm more than individuals receiving LP.

CONCLUSION

One-year-long complementary feeding with FS does not have a significantly larger effect than LP on mean weight gain in all infants, but it is likely to boost linear growth in the most disadvantaged individuals and, hence, decrease the incidence of severe stunting.

Feeding patterns of underweight children in rural Malawi given supplementary fortified spread at home

Fortified spread (FS), containing dry food particles embedded in edible fat, offers a convenient means for nutrition rehabilitation. To describe how caregivers feed FS to their undernourished children at home, and how FS use affects other feeding patterns, we conducted a longitudinal observational study in rural Malawi. Sixteen 6- to 17-month-old underweight children (weight-for-age z-score < -2.0; -3.0 < weight-for-height z-score < 0) received FS for 12 weeks. Twelve-hour observations were conducted before supplementation and during weeks 1, 4, 8 and 12 of FS use. FS was fed to children about two times per day; each serving was 15-20 g. The spread was first used mainly alone as a between-meal snack, and then became integrated into the typical complementary feeding pattern by being mixed with porridge. Introduction of FS reduced the number of plain porridge meals, but did not decrease the total number of meals or breastfeeds per day and did not change the daily mean time caregivers spent on feeding. Children accepted the FS well, but more FS was wasted when it was offered mixed with porridge than when given alone (23.6% vs. 1.2%, 95% CI for the difference 13.2% to 31.6%). FS supplementation is feasible for community-based nutrition interventions in Malawi because it easily becomes part of the feeding routine, does not replace other foods and does not take extra caregiver time. To limit wastage, caregivers should be advised to serve FS plain or to mix it with only a small quantity of porridge.

Nutrition and HIV/AIDS in infants and children in South Africa: implications for food-based dietary guidelines

The implications for food-based dietary guidelines (FBDGs) that are being developed in South Africa are reviewed in relation to HIV-exposed and -infected children. The nutritional consequences of HIV infection and nutritional requirements along with programmes and guidelines to address undernutrition and micronutrient deficiency in these children are also investigated. Based on studies for HIV-infected children in South Africa, more than 50% are underweight and stunted, while more than 60% have multiple micronutrient deficiencies. Nutritional problems in these children are currently addressed through the Prevention-of-Mother-to-Child Transmission Programme (PMTCT), the Integrated Nutrition Programme and Guidelines for the Management of HIV-infected Children which include antiretroviral (ARV) therapy in South Africa. Evaluations relating to the implementation of these programmes and guidelines have not been conducted nationally, although certain studies show that coverage of the PMTCT and the ARV therapy programmes was low. FBDGs for infants and young children could complement and strengthen the implementation of these programmes and guidelines. However, FBDGs must be in line with national and international guidelines and address key nutritional issues in these infants and young children. These issues and various recommendations are discussed in detail in this review.

[Management of severe acute malnutrition in an urban nutritional rehabilitation center in Burkina Faso]

BACKGROUND

Management of acute severe malnutrition greatly contributes to the reduction of childhood mortality rate. In developing countries, where malnutrition is common, number of acute severe malnutrition cases exceeds inpatient treatment capacity. Recent success of community-based therapeutic care put back on agenda the management of acute severe malnutrition. We analysed key issues of inpatient management of severe malnutrition to suggest appropriate global approach.

METHODS

Data of 1322 malnourished children, admitted in an urban nutritional rehabilitation center, in Burkina Faso, from 1999 to 2003 were analyzed. The nutritional status was assessed using anthropometrics indexes. Association between mortality and variables was measured by relative risks. Kaplan-Meier survival curves and Cox model were used.

RESULTS

From the 1322 hospitalized children, 8.5% dropped out. Daily weight gain was 10.18 (+/-7.05) g/kg/d. Among hospitalized malnourished children, 16% died. Patients were at high risk of early death, as 80% of deaths occurred during the first week. The risk of dying was highest among the severely malnourished: weight-for-height<-4 standard deviation (SD), RR=2.55 P<0,001; low MUAC-for-age, RR=2.05 P<0.001. Kaplan-Meier survival curves and Cox model showed that the variables most strongly associated with mortality were weight-for-height and MUAC-for-age. Among children discharged from the nutritional rehabilitation centre, 10.9% had weight-for-height<-3 SD.

CONCLUSION

The nutrition rehabilitation centre is confronted with extremely ill children with high risk of death. There is need to support those units for appropriate management of acute severe malnutrition. It is also important to implement community-based therapeutic care for management of children still malnourished at discharge from nutritional rehabilitation centre. These programs will contribute to reduce mortality rate and number of severely malnourished children attending inpatient nutrition rehabilitation centers, by prevention and early management.

A large-scale operational study of home-based therapy with ready-to-use therapeutic food in childhood malnutrition in Malawi

Home-based therapy with ready-to-use therapeutic food (RUTF) for the treatment of malnutrition has better outcomes in the research setting than standard therapy. This study examined outcomes of malnourished children aged 6-60 months enrolled in operational home-based therapy with RUTF. Children enrolled in 12 rural centres in southern Malawi were diagnosed with moderate or severe malnutrition according to the World Health Organization guidelines. They were treated with 733 kJ kg(-1) day(-1) of RUTF and followed fortnightly for up to 8 weeks. Staff at each centre followed one of three models: medical professionals administered treatment (5 centres), patients were referred by medical professionals and treated by community health aids (4 centres), or community health aids administered treatment (3 centres). The primary outcome of the study was clinical status, defined as recovered, failed, died or dropped out. Regression modelling was conducted to determine what aspects of the centre (formal training of staff, location along a main road) contributed to the outcome. Of 2131 severely malnourished children and 806 moderately malnourished, 89% and 85% recovered, respectively. Thirty-four (4%) of the moderately malnourished children failed, with 20 (2%) deaths, and 61 (3%) of the severely malnourished children failed, with 29 (1%) deaths. Centre location along a road was associated with a poor outcome. Outcomes for severely malnourished children were acceptable with respect to both the Sphere guidelines and the Prudhon case fatality index. Home-based therapy with RUTF yields acceptable results without requiring formally medically trained personnel; further implementation in comparable settings should be considered.

Breast milk intake is not reduced more by the introduction of energy dense complementary food than by typical infant porridge

The effect of different energy densities of complementary foods on breast milk consumption is not well understood. In this study, we tested the hypothesis that provision of fortified spread (FS), a micronutrient fortified, energy-dense (22 kJ/g), ready-to-use food, to Malawian infants would not decrease their breast milk intake more than a traditional corn + soy blended flour (CSB). Forty-four healthy 6-mo-old infant and mother pairs were enrolled in a prospective, parallel group, investigator-blinded, randomized controlled complementary feeding trial. Infants were randomized to receive 25 g/d of FS, 50 g/d of FS, or 72 g/d of CSB. The primary outcome was the difference in breast milk intake after 1 mo of complementary feeding as measured by the dose-to-mother deuterium oxide dilution technique. Outcomes were compared using repeated measures ANOVA. A total of 41 mother-infant pairs completed the study. At enrollment, 88% of the infants had received corn porridge. At baseline, the infants consumed 129 +/- 18 g.kg body wt(-1) x d(-1) (mean +/- SD) of breast milk. After 1 mo of complementary feeding with 25 g/d FS, 50 g/d FS, or 72 g/d CSB, their breast milk consumption was 115 +/- 18 g.kg body wt(-1) x d(-1), a significant reduction; however, the effects of the complementary foods did not differ from one another (F-value model = 4.33, P = 0.0008 for effect of time and P = 0.69 for effect of type of food). The results suggest that complementary feeding of Malawian infants with FS has the same effect on their breast milk intake as complementary feeding with traditional CSB porridge.

Treating severe acute malnutrition seriously

Severe acute malnutrition (SAM) affects approximately 13 million children under the age of 5 and is associated with 1-2 million preventable child deaths each year. In most developing countries, case fatality rates (CFRs) in hospitals treating SAM remain at 20-30% and few of those requiring care actually access treatment. Recently, community-based therapeutic care (CTC) programmes treating most cases of SAM solely as outpatients have dramatically reduced CFRs and increased the numbers receiving care. CTC uses ready-to-use therapeutic foods and aims to increase access to services, promoting early presentation and compliance, thereby increasing coverage and recovery rates. Initial data indicate that this combination of centre-based and community-based care is cost effective and should be integrated into mainstream child survival programmes.

Efficacy and effectiveness of community-based treatment of severe malnutrition

BACKGROUND

There is a long tradition of community-based rehabilitation for treatment of severe malnutrition: the question is whether it is effective and whether it should be advised for routine health systems.

OBJECTIVE

To examine the effectiveness of rehabilitating severely malnourished children in the community in nonemergency situations.

METHODS

A literature search was conducted of community-based rehabilitation programs delivered by day-care nutrition centers, residential nutrition centers, primary health clinics, and domiciliary care with or without provision of food, for the period 1980-2005. Effectiveness was defined as mortality of less than 5% and an average weight gain of at least 5 g/kg/day.

RESULTS

Thirty-three studies of community-based rehabilitation were examined and summarized. Eleven (33%) programs were considered effective. Of the sub-sample of programs reported since 1995, 8 of 13 (62%) were effective. None of the programs operating within routine health systems without external assistance was effective.

CONCLUSIONS

With careful planning and resources, all four delivery systems can be effective. It is unlikely that a single delivery system would suit all situations worldwide. The choice of a system depends on local factors. High energy intakes (> 150 kcal/kg/day), high protein intakes (4-6 g/kg/day), and provision of micronutrients are essential for success. When done well, rehabilitation at home with family foods is more cost-effective than inpatient care, but the cost effectiveness of ready-to-use therapeutic foods (RUTF) versus family foods has not been studied. Where children have access to a functioning primary health-care system and can be monitored, the rehabilitation phase of treatment of severe malnutrition should take place in the community rather than in the hospital but only if caregivers can make energy- and protein-dense food mixtures or are given RUTF. For routine health services, the cost of RUTF, logistics of procurement and distribution, and sustainability need to be carefully considered.

The effect of nutritional support on weight gain of HIV-infected children with prolonged diarrhoea

AIM

To examine the effect on growth and immunity of enhanced calorie and protein provision to HIV-infected children presenting with prolonged diarrhoea.

METHODS

A total of 169 HIV-infected children aged 6-36 months with diarrhoea for 7 days or more were randomly assigned to either standard nutrition support for children with prolonged diarrhoea or an enhanced diet started during hospitalisation and continued after discharge. The change in weight between enrolment and 8, 14 and 26 weeks and changes in plasma HIV-RNA and CD4 cell count at 8 and 26 weeks were estimated.

RESULTS

Children receiving enhanced nutrition achieved significantly more weight gain (p < 0.001) between enrolment and 8 weeks than children on the standard diet (median increase in weight-for-age standard deviation score +1.02 vs. +0.01). After 8 weeks median weight velocity was normal and similar in both groups. The change in median CD4 count was similar in both groups. The 26-week mortality rate was high in both groups (standard support: 22%, enhanced support: 29%).

CONCLUSIONS

Nutrition support of children with advanced HIV infection and prolonged diarrhoea resulted in significant and sustained weight gain, but did not improve CD4 counts or survival. These results support integrated nutrition interventions for HIV-infected children.

Management of severe acute malnutrition in children

Severe acute malnutrition (SAM) is defined as a weight-for-height measurement of 70% or less below the median, or three SD or more below the mean National Centre for Health Statistics reference values, the presence of bilateral pitting oedema of nutritional origin, or a mid-upper-arm circumference of less than 110 mm in children age 1-5 years. 13 million children under age 5 years have SAM, and the disorder is associated with 1 million to 2 million preventable child deaths each year. Despite this global importance, child-survival programmes have ignored SAM, and WHO does not recognise the term "acute malnutrition". Inpatient treatment is resource intensive and requires many skilled and motivated staff. Where SAM is common, the number of cases exceeds available inpatient capacity, which limits the effect of treatment; case-fatality rates are 20-30% and coverage is commonly under 10%. Programmes of community-based therapeutic care substantially reduce case-fatality rates and increase coverage rates. These programmes use new, ready-to-use, therapeutic foods and are designed to increase access to services, reduce opportunity costs, encourage early presentation and compliance, and thereby increase coverage and recovery rates. In community-based therapeutic care, all patients with SAM without complications are treated as outpatients. This approach promises to be a successful and cost-effective treatment strategy.

Growth and change in blood haemoglobin concentration among underweight Malawian infants receiving fortified spreads for 12 weeks: a preliminary trial

OBJECTIVE

Fortified spreads (FSs) have proven effective in the rehabilitation of severely malnourished children. We examined acceptability, growth and change in blood haemoglobin (Hb) concentration among moderately underweight ambulatory infants given FS.

METHODS

This was a randomised, controlled, parallel-group, investigator-blind clinical trial in rural Malawi. Six- to 17-month-old underweight infants (weight for age < -2), whose weight was greater than 5.5 kg and weight-for-height z score greater than -3 received for 12 weeks at home 1 of 8 food supplementation schemes: nothing, 5, 25, 50, or 75 g/day milk-based FS or 25, 50, or 75 g/day soy-based FS. Outcome measures included change in weight, length and blood Hb concentration.

RESULTS

A total of 126 infants started and 125 completed the intervention. All infants accepted the spread well, and no intolerance was recorded. Average weight and length gains were higher among infants receiving daily 25 to 75 g FS than among those receiving only 0 to 5 g FS. Mean Hb concentration remained unchanged among unsupplemented controls but increased by 10 to 17 g/L among infants receiving any FS. All average gains were largest among infants receiving 50 g of FS daily: mean difference (95% confidence interval) in the 12-week gain between infants in 50 g milk-based FS group and the unsupplemented group was 290 g (range, -130 to 700 g), 0.9 cm (range, -0.3 to 2.2 cm), and 17 g/L (range, 0 to 34 g/L) for weight, length and blood Hb concentration, respectively. In soy- vs milk-based FS groups, average outcomes were comparable.

CONCLUSIONS

Supplementation with 25 to 75 g/day of highly fortified spread is feasible and may promote growth and alleviate anaemia among moderately malnourished infants. Further trials should test this hypothesis.

Critical appraisal of the management of severe malnutrition: 2. Dietary management

In the dietary management of severe acute malnutrition in children, there is evidence to support the WHO Manual's protocol of cautious feeding of a low energy and protein formula with small frequent feeds in the initial phase of treatment, particularly in kwashiorkor. However, this initial milk diet (WHO F-75) might benefit from increasing the sulphur amino acid, phosphorus and potassium content and reducing the lactose content, but further studies are needed. Careful tube-feeding results in faster initial recovery and weight gain, but has a significant risk of aspiration in poorly supervised settings. Ready-to-use therapeutic food is an important recent advance in the dietary management of malnutrition in ambulatory settings, allowing more effective prevention programmes and earlier discharge from hospital where community follow-up is available. It should be included in future protocols. There is very good evidence on the use of micronutrients such as zinc, and preliminary evidence suggests that smaller doses of daily vitamin A are preferable to a single large dose on admission for severe malnutrition.

Home-based therapy for oedematous malnutrition with ready-to-use therapeutic food

BACKGROUND

Standard recommendations are that children with oedematous malnutrition receive inpatient therapy with a graduated feeding regimen.

AIM

To investigate exclusive home-based therapy for children with oedematous malnutrition.

METHODS

Children with oedematous malnutrition, good appetite and no complications were treated at home with ready-to-use therapeutic food (RUTF) and followed up fortnightly for up to 8 wk.

SETTING AND PARTICIPANTS

219 children aged 1-5 y with oedema enrolled in one of two therapeutic nutritional studies in Malawi in 2003-2004.

RESULTS

The overall recovery rate was 83% (182/219), and the case-fatality rate was 5% (11/219). For children with wasting and oedematous malnutrition, 65% (55/85) recovered and 7% (6/85) died. The average weight gain was 2.8+/-3.2 g/kg/d (mean+/-SD).

CONCLUSION

This preliminary observation suggests that children with oedematous malnutrition and good appetite may be successfully treated with home-based therapy; a randomized, controlled trial to evaluate this is warranted.

Community-based therapeutic care in HIV-affected populations

Community-based therapeutic care (CTC) is a community-based model for delivering care to malnourished people. CTC aims to treat the majority of severely malnourished people at home, rather than in therapeutic feeding centres. This paper describes the potential of the CTC approach to provide effective care and support for people living with HIV and AIDS (PLWHA). CTC includes many of the components of a home-based care model for PLWHA. It provides outpatient treatment for common complications of HIV and AIDS, such as acute malnutrition and simple infections, and an energy-dense ready-to-use food that could be made with the appropriate balance of micronutrients for the HIV-infected patient. Through the de-centralisation of outpatient treatment sites, CTC improves accessibility by moving treatment closer to people's homes and helps to promote the sustainability of care by building on the capacity of existing health infrastructure and staff. The CTC model contains many features that are appropriate for the care and support of HIV-affected people and, in its present form, can provide effective physical care for many HIV-affected individuals. We are currently working to adapt the CTC model to make it more suitable for the support of PLWHA in the longer term.

Antioxidant supplementation for the prevention of kwashiorkor in Malawian children: randomised, double blind, placebo controlled trial

OBJECTIVE

To evaluate the efficacy of antioxidant supplementation in preventing kwashiorkor in a population of Malawian children at high risk of developing kwashiorkor.

DESIGN

Prospective, double blind, placebo controlled trial randomised by household.

SETTING

8 villages in rural southern Malawi.

PARTICIPANTS

2372 children in 2156 households aged 1-4 years were enrolled; 2332 completed the trial.

INTERVENTION

Daily supplementation with an antioxidant powder containing riboflavin, vitamin E, selenium, and N-acetylcysteine in a dose that provided about three times the recommended dietary allowance of each nutrient or placebo for 20 weeks.

MAIN OUTCOME MEASURES

The primary outcome was the incidence of oedema. Secondary outcomes were the rates of change for weight and length and the number of days of infectious symptoms.

RESULTS

62 children developed kwashiorkor (defined by the presence of oedema); 39/1184 (3.3%) were in the antioxidant group and 23/1188 (1.9%) were in the placebo group (relative risk 1.70, 95% confidence interval 0.98 to 2.42). The two groups did not differ in rates of weight or height gain. Children who received antioxidant supplementation did not experience less fever, cough, or diarrhoea.

CONCLUSIONS

Antioxidant supplementation at the dose provided did not prevent the onset of kwashiorkor. This finding does not support the hypothesis that depletion of vitamin E, selenium, cysteine, or riboflavin has a role in the development of kwashiorkor.

Comparison of home-based therapy with ready-to-use therapeutic food with standard therapy in the treatment of malnourished Malawian children: a controlled, clinical effectiveness trial

BACKGROUND

Childhood malnutrition is common in Malawi, and the standard treatment, which follows international guidelines, results in poor recovery rates. Higher recovery rates have been seen in pilot studies of home-based therapy with ready-to-use therapeutic food (RUTF).

OBJECTIVE

The objective was to compare the recovery rates among children with moderate and severe wasting, kwashiorkor, or both receiving either home-based therapy with RUTF or standard inpatient therapy.

DESIGN

A controlled, comparative, clinical effectiveness trial was conducted in southern Malawi with 1178 malnourished children. Children were systematically allocated to either standard therapy (186 children) or home-based therapy with RUTF (992 children) according to a stepped wedge design to control for bias introduced by the season of the year. Recovery, defined as reaching a weight-for-height z score > -2, and relapse or death were the primary outcomes. The rate of weight gain and the prevalence of fever, cough, and diarrhea were the secondary outcomes.

RESULTS

Children who received home-based therapy with RUTF were more likely to achieve a weight-for-height z score > -2 than were those who received standard therapy (79% compared with 46%; P < 0.001) and were less likely to relapse or die (8.7% compared with 16.7%; P < 0.001). Children who received home-based therapy with RUTF had greater rates of weight gain (3.5 compared with 2.0 g . kg(-1) . d(-1); difference: 1.5; 95% CI: 1.0, 2.0 g . kg(-1) . d(-1)) and a lower prevalence of fever, cough, and diarrhea than did children who received standard therapy.

CONCLUSION

Home-based therapy with RUTF is associated with better outcomes for childhood malnutrition than is standard therapy.

An assessment of food supplementation to chronically sick patients receiving home based care in Bangwe, Malawi: a descriptive study

BACKGROUND

The effect of food supplementation provided by the World Food Programme to patients and their families enrolled in a predominantly HIV/AIDS home based care programme in Bangwe Malawi is assessed.

METHODS

The survival and nutritional status of patients and the nutritional status of their families recruited up to six months before a food supplementation programme started are compared to subsequent patients and their families over a further 12 months.

RESULTS

360 patients, of whom 199 died, were studied. Food supplementation did not improve survival but had an effect (not statistically significant) on nutritional status. Additional oil was given to some families; it may have improved survival but not nutritional status.

CONCLUSION

Food supplementation to HIV/AIDS home based care patients and their families does not work well. This may be because the intervention is too late to affect the course of disease or insufficiently targeted perhaps due to problems of distribution in an urban setting. The World Food Programme's emphasis on supplementary feeding for these families needs to be reviewed.

Home-based therapy with ready-to-use therapeutic food is of benefit to malnourished, HIV-infected Malawian children

AIM

To determine if home-based nutritional therapy will benefit a significant fraction of malnourished, HIV-infected Malawian children, and to determine if ready-to-use therapeutic food (RUTF) is more effective in home-based nutritional therapy than traditional foods.

METHODS

93 HIV-positive children >1 y old discharged from the nutrition unit in Blantyre, Malawi were systematically allocated to one of three dietary regimens: RUTF, RUTF supplement or blended maize/soy flour. RUTF and maize/soy flour provided 730 kJ x kg(-1) x d(-1), while the RUTF supplement provided a fixed amount of energy, 2100 kJ/d. These children did not receive antiretroviral chemotherapy. Children were followed fortnightly. Children completed the study when they reached 100% weight-for-height, relapsed or died. Outcomes were compared using regression modeling to account for differences in the severity of malnutrition between the dietary groups.

RESULTS

52/93 (56%) of all children reached 100% weight-for-height. Regression modeling found that the children receiving RUTF gained weight more rapidly and were more likely to reach 100% weight-for-height than the other two dietary groups (p < 0.05).

CONCLUSION

More than half of malnourished, HIV-infected children not receiving antiretroviral chemotherapy benefit from home-based nutritional rehabilitation. Home-based therapy RUTF is associated with more rapid weight gain and a higher likelihood of reaching 100% weight-for-height.

Home-based treatment of malnourished Malawian children with locally produced or imported ready-to-use food

OBJECTIVES

To determine the efficacy of home-based therapy with ready-to-use food (RTUF) in producing catch-up growth in malnourished children and to compare locally produced RTUF with imported RTUF for this purpose.

METHODS

After a brief inpatient stabilization, 260 children with severe malnutrition were enrolled and systematically allocated to receive home therapy with either imported, commercially produced RTUF or locally produced RTUF. Each child received 730 kJ/kg/day and was followed up fortnightly. Children completed the study when they reached a weight-for-height Z score > -0.5 (WHZ), relapsed, died, or failed to achieve WHZ > -0.5 after 16 weeks. Analyses were stratified by human immunodeficiency virus (HIV) status.

RESULTS

78% of all children reached WHZ > -0.5, 95% of those with HIV-negative status and 59% of those with HIV-positive status. Eighty percent of those receiving locally produced RTUF and 75% of those receiving imported RTUF reached WHZ > -0.5. The difference between recovery rates was 5% (95% confidence interval [CI], -5-15%). The rate of weight gain was 0.4 g/kg/day (95% CI, -0.6, 1.4) greater among children receiving locally produced RTUF. The prevalence of diarrhea reported by mothers was 3.7% for locally produced RTUF and 4.3% for imported RTUF. After completion of home therapy and resumption of habitual diet for 6 months, 91% of all children maintained a normal WHZ.

CONCLUSIONS

Home-based therapy with RTUF was successful in affecting complete catch-up growth. In this study, locally produced and imported RTUF were similar in efficacy in treating of severe childhood malnutrition.
