Growth, morbidity, and mortality of children in Dhaka after treatment for severe malnutrition: a prospective study

Impact of diarrhoea and acute respiratory infection on environmental enteric dysfunction and growth of malnourished children in Pakistan: a longitudinal cohort study

Background

Diarrhoea and acute respiratory infections (ARI) are assumed to be major drivers of growth and likely contribute to environmental enteric dysfunction (EED), which is a precursor to childhood malnutrition. In the present study, we checked the correlation between diarrhoeal/ARI burden and EED using a novel duodenal histological index.

Methods

Between November 2017 and July 2019, a total of 365 infants with weight-for-height Z scores (WHZ score) of <-2 were enrolled, and 51 infants with WHZ scores of >0 and height-for-age Z scores (HAZ scores) of >-1 were selected as age-matched healthy controls. Morbidity was assessed weekly and categorised as the total number of days with diarrhoea and acute respiratory infection (ARI) from enrolment until two years of age and was further divided into four quartiles in ascending order.

Findings

The HAZ declined until two years of age regardless of morbidity burden, and WHZ and weight-for-age Z scores (WAZ scores) were at their lowest at six months. Sixty-three subjects who had a WHZ score <-2 and failed to respond to nutritional and educational interventions were further selected at 15 months to investigate their EED histological scores with endoscopy further. EED histological scores of the subjects were higher with increasing diarrhoeal frequency yet remained statistically insignificant (p = 0.810).

Interpretation

There was not a clear correlation between diarrhoea and ARI frequency with growth faltering, however, children with the highest frequency of diarrhoea had the highest EED histological scores and growth faltering.

Evaluation of the Health and Nutritional Status of Discharged Children From Malnutrition Treatment Centres Using Mobile Phone Calls During the COVID-19 Lockdown in Jharkhand, India

Background The Indian state of Jharkhand has the highest rate of wasting (29%) among young children. Mobile audio call follow-up can be used to assess such children with severe acute malnutrition (SAM). Aim This study evaluated SAM children during the COVID-19 outbreak and learn more about the status of their home/community care, and caregivers' awareness of integrated child development services (ICDS) and COVID-19 prevention. Methods Contact numbers of caregivers for discharged children were obtained from 54 malnutrition treatment centers (MTCs). In April and June 2020, mentors conducted follow-up interviews using mobile phone calls. Results Seven children (1.72%) were reported dead and 400 were alive, mostly girls (59.5%). Only a few caregivers observed post-discharge ailments (15.4%) and weight loss (7.7%) in their children. Children aged six to 24 months were characterized by continued breastfeeding (88.0%) at most five to six times a day (45.8%). Most of the children were not fed as per maternal infant and young child feeding protocols. Age in months with an adjusted odds ratio (OR) of 0.55 (1.00-1.11) as a 95% confidence interval (CI), age category, with an adjusted OR of 4.32 (1.71- 10.94) as 95% CI, and breastfeeding with adjusted OR 1.85 (1.07- 3.21) as 95% CI were three major predictors for a well-fed child. Conclusion Community involvement is crucial in the follow-up of children with SAM for effective rehabilitation. Mobile phone audio call follow-up is a relatively cost-effective approach to tackle geographic barriers and COVID-19 lockdown-induced situations. There are major gaps mainly in informing caregivers on how to manage COVID-19 with breastfeeding.

Burden and risk factors for relapse following successful treatment of uncomplicated severe acute malnutrition in young children: Secondary analysis from a randomised trial in Niger

This study aimed to quantify the burden of relapse following successful treatment for uncomplicated severe acute malnutrition (SAM) and to identify associated risk factors in rural Niger. We used data from 1490 children aged 6−59 months discharged as recovered from an outpatient nutritional programme for SAM and followed for up to 12 weeks after admission. Postdischarge SAM relapse was defined as weight‐for‐height Z‐score <−3, mid‐upper arm circumference (MUAC) <115 mm or bipedal oedema after having been discharged as recovered. Postdischarge hospitalisation was defined as admission to inpatient SAM treatment or hospitalisation for any cause after having been discharged as recovered. We used multivariate log‐binomial models to identify independent risk factors. After programmatic discharge, 114 (8%) children relapsed to SAM and 89 (6%) were hospitalised. Factors associated with SAM relapse were discharge during the lean season (relative risk [RR] = 1.80 [95% confidence interval [CI] = 1.22−2.67]) and larger household size (RR = 1.56 [95% CI = 1.01−2.41]), whereas older child age (RR = 0.94 [95% CI = 0.88−1.00]), higher child MUAC at discharge (RR = 0.93 [95% CI = 0.87−1.00]) and maternal literacy (RR = 0.54 [95% CI = 0.29−0.98]) were protective factors. Discharge during the lean season (RR = 2.27 [95% CI = 1.46−3.51]) was independently associated with postdischarge hospitalisation. Future nutritional programmes in the context of Niger may consider modification of anthropometric discharge criteria or the provision of additional home support or follow‐up during the lean season as potential interventions to prevent relapse. More research including postdischarge follow‐up is needed to better understand the sustainability of treatment outcomes after discharge and the type of intervention that may best sustain recovery over time. Clinical Trial Registration: ClinicalTrials.gov number, NCT01613547.

Following successful discharge from a community‐based nutritional programme for severe acute malnutrition (SAM) treatment in rural Niger, the prevalence of SAM relapse was 8% and the prevalence of postdischarge hospitalisation was 6% within 12 weeks from admission.

Factors associated with SAM relapse were child age at programme admission, child mid‐upper arm circumference (MUAC) at discharge, discharge from the nutritional programme during the lean season, and maternal literacy.

Anthropometry at discharge was a primary risk factor for relapse. MUAC at discharge performed better than weight‐for‐height Z‐score (WHZ) in classifying SAM relapse cases. ‘Optimal’ cut‐offs, defined using the Liu method which maximises the product of the sensitivity and specificity, were MUAC of 121 mm with 66% sensitivity and 67% specificity and WHZ of −1.38 with 54% sensitivity and 57% specificity.

Future programmes may consider additional support or follow‐up of children at high risk of postdischarge relapse or hospitalisation, including those discharged during the lean season. Modification of current anthropometric discharge criteria may also be explored as an actionable target to further reduce the risk of relapse.

Recovery of children following hospitalisation for complicated severe acute malnutrition

Nutritional recovery and hospital readmission following inpatient management of complicated severe acute malnutrition (SAM) are poorly characterised. We aimed to ascertain patterns and factors associated with hospital readmission, nutritional recovery and morbidity, in children discharged from hospital following management of complicated SAM in Zambia and Zimbabwe over 52‐weeks posthospitalization. Multivariable Fine‐Gray subdistribution hazard models, with death and loss to follow‐up as competing risks, were used to identify factors associated with hospital readmission; negative binomial regression to assess time to hospitalisation and ordinal logistic regression to model factors associated with nutritional recovery. A total of 649 children (53% male, median age 18.2 months) were discharged to continue community nutritional rehabilitation. All‐cause hospital readmission was 15.4% (95% CI 12.7, 18.6) over 52 weeks. Independent risk factors for time to readmission were cerebral palsy (adjusted subhazard ratio (aSHR): 2.96, 95% CI 1.56, 5.61) and nonoedematous SAM (aSHR: 1.64, 95%CI 1.03, 2.64). Unit increases in height‐for‐age Z‐score (HAZ) (aSHR: 0.82, 95% CI 0.71, 0.95) and enrolment in Zambia (aSHR: 0.52, 95% CI 0.28, 0.97) were associated with reduced subhazard of time to readmission. Young age, SAM at discharge, nonoedematous SAM and cerebral palsy were associated with poor nutritional recovery throughout follow‐up. Collectively, nonoedematous SAM, ongoing SAM at discharge, cerebral palsy and low HAZ are independent risk factors for readmission and poor nutritional recovery following complicated SAM. Children with these high‐risk features should be prioritised for additional convalescent care to improve long‐term outcomes.

One‐in‐six children managed for SAM were readmitted into hospital over the first year after discharge and one‐in‐eight remained undernourished by 52 weeks of follow‐up.

Nonoedematous SAM, ongoing SAM at the time of discharge and underlying cerebral palsy were independent risk factors for hospital readmission and poor nutritional recovery.

Low HAZ was a risk factor for hospital readmission and poor nutritional recovery.

Postdischarge care should focus on children with disability, nonoedematous SAM at initial hospitalisation and have ongoing SAM at the time of discharge.

Stunting should be considered in the management of children with SAM.

Weight-for-Height Z-score Gain during Inpatient Treatment and Subsequent Linear Growth during Outpatient Treatment of Young Children with Severe Acute Malnutrition: A Prospective Study from Uganda

BACKGROUND

Linear catch-up growth after treatment of severe acute malnutrition (SAM) is low, and little is known about the association between ponderal and subsequent linear growth.

OBJECTIVE

The study assessed the association of weight-for-height z-score (WHZ) gain with subsequent linear growth during SAM treatment and examined its modifiers.

METHODS

This was a prospective study, nested in a trial (ISRCTN16454889), among 6-59-mo-old children treated for SAM in Uganda. Weight, total length (TL), and knee-heel length (KHL) were measured at admission, weekly during inpatient therapeutic care (ITC), at discharge, and fortnightly during outpatient therapeutic care (OTC) for 8 wk. Linear regression was used to assess the association between WHZ gain during ITC and linear growth during OTC.

RESULTS

Of 400 children, 327 were discharged to OTC and 290 were followed up for 8 wk. Mean WHZ gains were 0.45 in ITC and 1.24 in OTC, whereas mean height-for-age z-score (HAZ) declined by 0.41 during ITC and increased by 0.14 during OTC. WHZ gain during ITC was positively associated with HAZ, TL, and KHL gains during OTC [regression coefficients (β) (95% CI): 0.12 (0.09, 0.15) z-score; 3.1 (2.4, 3.8) mm and 0.5 (0.1, 0.7) mm, respectively]. The regression coefficients were highest for the middle tertile of WHZ gain with respect to HAZ and TL. Admission diarrhea and low plasma citrulline reduced the association between WHZ gain during ITC and HAZ and TL gain during OTC (P < 0.001). In contrast, pneumonia (P = 0.051) and elevated plasma C-reactive protein (P < 0.001) increased the association with TL gain, but reduced the association with KHL gain (P < 0.001).

CONCLUSIONS

Among children admitted with SAM, considerable WHZ gain during ITC was followed by very modest linear catch-up growth during OTC, with no indication of a WHZ gain threshold, above which linear growth was higher. To optimize linear growth in these children, early treatment of infections and conditions affecting the gut may be necessary.

100 days outcome of severe wasting in hospitalised infants <6 months of age

OBJECTIVE

To assess the outcome of severe wasting in infants below 6 months of age.

DESIGN

A prospective observational study conducted between January 2017 and October 2018.

SETTING

A medical college-affiliated hospital in Eastern Delhi, catering mainly to the urban poor population.

PARTICIPANTS

All children with severe wasting (weight-for-length Z-score (WLZ) < -3 sd) between 1 and 6 months of age, requiring hospitalisation.

RESULTS

Out of fifty children enrolled, during hospitalisation, forty-two (84 %) recovered (WLZ > -3 sd) and discharged; the median (interquartile range (IQR)) duration of stay was 9·5 (6·5, 13·0) d. After 100 d of enrolment, sustained cure (WLZ > -2 SD) could be achieved in only fifteen (30 %) infants, while another fourteen (28 %) recovered from severe wasting, but remained in moderately wasted state (WLZ between -2 and -3 sd). Overall, there were three (6 %) deaths (all during first week of hospitalisation); three (6 %) relapses and fifteen (30 %) defaulters (5, 5, 2, 1 and 2 defaulted during hospitalisation at day 15, day 60, day 75 and day 90, respectively).

CONCLUSIONS

The overall recovery rate from severe wasting in infants below 6 months of age was below the acceptable levels. In order to achieve better long-term outcome, community linkage services after discharge from hospital are required for supervised feeding, close monitoring and supportive care.

Risk factors for postdischarge mortality following hospitalization for severe acute malnutrition in Zimbabwe and Zambia

BACKGROUND

Children discharged from hospital following management of complicated severe acute malnutrition (SAM) have a high risk of mortality, especially HIV-positive children. Few studies have examined mortality in the antiretroviral therapy (ART) era.

OBJECTIVES

Our objectives were to ascertain 52-wk mortality in children discharged from hospital for management of complicated SAM, and to identify independent predictors of mortality.

METHODS

A prospective cohort study was conducted in children enrolled from 3 hospitals in Zambia and Zimbabwe between July 2016 and March 2018. The primary outcome was mortality at 52 wk. Univariable and multivariable Cox regression models were used to identify independent risk factors for death, and to investigate whether HIV modifies these associations.

RESULTS

Of 745 children, median age at enrolment was 17.4 mo (IQR: 12.8, 22.1 mo), 21.7% were HIV-positive, and 64.4% had edema. Seventy children (9.4%; 95% CI: 7.4, 11.7%) died and 26 exited during hospitalization; 649 were followed postdischarge. At discharge, 43.9% had ongoing SAM and only 50.8% of HIV-positive children were receiving ART. Vital status was ascertained for 604 (93.1%), of whom 55 (9.1%; 95% CI: 6.9, 11.7%) died at median 16.6 wk (IQR: 9.4, 21.9 wk). Overall, 20.0% (95% CI: 13.5, 27.9%) and 5.6% (95% CI: 3.8, 7.9%) of HIV-positive and HIV-negative children, respectively, died [adjusted hazard ratio (aHR): 3.83; 95% CI: 2.15, 6.82]. Additional independent risk factors for mortality were ongoing SAM (aHR: 2.28; 95% CI: 1.22, 4.25), cerebral palsy (aHR: 5.60; 95% CI: 2.72, 11.50) and nonedematous SAM (aHR: 2.23; 95% CI: 1.24, 4.01), with no evidence of interaction with HIV status.

CONCLUSIONS

HIV-positive children have an almost 4-fold higher mortality than HIV-negative children in the year following hospitalization for complicated SAM. A better understanding of causes of death, an improved continuum of care for HIV and SAM, and targeted interventions to improve convalescence are needed.

Effect of malnutrition on length of hospital stay in children

Objective

To determine the prevalence of malnutrition in hospitalized pediatric patients, to provide a classification of patients with malnutrition, and to evaluate the effect of malnutrition on length of hospital stay.

Material and Methods

The study included patients aged 5 months to 18 years who were hospitalized in the Department of Pediatrics of the Adana City Training and Research Hospital between May 1^st, 2018, and December 31^st, 2018. Bodyweight, height, mid-upper arm circumference, and triceps skinfold thickness were measured at the time of hospitalization, and age, sex, diagnosis, comorbid conditions, and length of stay for treatment were recorded.

Results

Of 1009 patients, 44% were female and 56% were male, and the mean age was 59.9±58.6 (median age 32) months. The mean length of stay was 6.83±4.48 days. Malnutrition was determined in 46.9% of the patients according to the Gomez classification. The mean length of stay in patients without malnutrition was 6.31±3.86 days, compared with 7.39±5.04 days in patients with malnutrition (p<0.001). The length of stay increased with increasing degrees of malnutrition (p<0.001).

Conclusion

Malnutrition is often overlooked in hospitalized patients. Studies conducted in different years that reported similar malnutrition rates indicated that this condition still existed as a significant health problem. In the evaluation of nutritional status in hospitalized patients, paying attention to malnutrition while addressing the main reason of hospitalization and incorporating nutritional support into the treatment plan will decrease the length of stay and also reduce the rate of complications.

[Nutritional recovery after discharge in hospitalized children with malnutrition]

OBJECTIVE

To investigate the nutritional recovery status of children with moderate or severe malnutrition during hospitalization after discharge.

METHODS

The children with moderate or severe malnutrition were given nutrition support during hospitalization. They received a regular follow-up and nutrition guidance after discharge. The weight-for-age and height-for-age Z-scores reaching above -2 SD were considered the nutrition criterion for ending follow-up.

RESULTS

Among the 298 children with moderate or severe malnutrition, 174 (58.4%) reached the criterion for ending follow-up, 100 (33.6%) were lost to follow-up, 18 (6.0%) died, and 6 (2.0%) did not reach the criterion for ending follow-up after 18 months of follow-up. The children with malnutrition in the department of surgery had a significantly higher proportion of children reaching the criterion for ending follow-up than those in the department of internal medicine (P<0.05). The children with severe malnutrition had a significantly higher loss to follow-up rate than those with moderate nutrition (P<0.05). The majority of children with emaciation reached the criterion for ending follow-up at month 3 after discharge, while those with growth retardation reached such the criterion at months 3-6 after discharge. Up to 1 year after discharge, more than 80% of the children with different types of malnutrition reached the nutrition criterion for ending follow-up.

CONCLUSIONS

Most of the children with malnutrition who adhere to follow-up can reach the expected nutrition criterion within 1 year after discharge. The children with growth retardation have slower nutritional recovery than those with emaciation.

Follow-up of a historic cohort of children treated for severe acute malnutrition between 1988 and 2007 in Eastern Democratic Republic of Congo

BACKGROUND

It is well documented that treatment for severe acute malnutrition (SAM) is effective. However, little is known about the long-term outcomes for children treated for SAM. We sought to trace former SAM patients 11 to 30 years after their discharge from hospital, and to describe their longer-term survival and their growth to adulthood.

METHODS

A total of 1,981 records of subjects admitted for SAM between 1988 and 2007 were taken from the archives of Lwiro hospital, in South Kivu, DRC. The median age on admission was 41 months. Between December 2017 and June 2018, we set about identifying these subjects (cases) in the health zones of Miti-Murhesa and Katana. For deceased subjects, the cause and year of death were collected. A Cox proportional hazards multivariate regression analysis was used to identify the death-related factors. For the cases seen, age- and gender-matched community controls were selected for a comparison of anthropometric indicators.

RESULTS

A total of 600 subjects were traced, and 201 subjects were deceased. Of the deceased subjects, 65·6% were under 10 years old at the time of their death. Of the deaths, 59·2% occurred within 5 years of discharge from hospital. The main causes of death were malaria (14·9%), kwashiorkor (13·9%), respiratory infections (10·4%), and diarrhoeal diseases (8·9%). The risk of death was higher in subjects with SAM, MAM combined with CM, and in male subjects, with HRs* of 1·83 (p = 0·043), 2.35 (p = 0·030) and 1.44 (p = 0·013) respectively. Compared with their controls, the cases had a low weight (-1·7 kg, p = 0·001), short height [sitting (-1·3 cm, p = 0·006) and standing (-1·7 cm, p = 0·003)], short legs (-1·6 cm, p = 0·002), and a small mid-upper arm circumference (-3·2mm, p = 0·051). There was no difference in terms of BMI, thoracic length, or head and thoracic circumference between the two groups.

CONCLUSION

SAM during childhood has lasting negative effects on growth to adulthood. In addition, these adults have characteristics that may place them at risk of chronic non-communicable diseases later in life.

Phenotype is sustained during hospital readmissions following treatment for complicated severe malnutrition among Kenyan children: A retrospective cohort study

Hospital readmission is common among children with complicated severe acute malnutrition (cSAM) but not well‐characterised. Two distinct cSAM phenotypes, marasmus and kwashiorkor, exist, but their pathophysiology and whether the same phenotype persists at relapse are unclear. We aimed to test the association between cSAM phenotype at index admission and readmission following recovery. We performed secondary data analysis from a multicentre randomised trial in Kenya with 1‐year active follow‐up. The main outcome was cSAM phenotype upon hospital readmission. Among 1,704 HIV‐negative children with cSAM discharged in the trial, 177 children contributed a total of 246 readmissions with cSAM. cSAM readmission was associated with age<12 months (p = .005), but not site, sex, season, nor cSAM phenotype. Of these, 42 children contributed 44 readmissions with cSAM that occurred after a monthly visit when SAM was confirmed absent (cSAM relapse). cSAM phenotype was sustained during cSAM relapse. The adjusted odds ratio for presenting with kwashiorkor during readmission after kwashiorkor at index admission was 39.3 [95% confidence interval (95% CI) [2.69, 1,326]; p = .01); and for presenting with marasmus during readmission after kwashiorkor at index admission was 0.02 (95% CI [0.001, 0.037]; p = .01). To validate this finding, we examined readmissions to Kilifi County Hospital, Kenya occurring at least 2 months after an admission with cSAM. Among 2,412 children with cSAM discharged alive, there were 206 readmissions with cSAM. Their phenotype at readmission was significantly influenced by their phenotype at index admission (p < .001). This is the first report describing the phenotype and rate of cSAM recurrence.

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

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

Linear growth following complicated severe malnutrition: 1-year follow-up cohort of Kenyan children

BACKGROUND

Stunting is the most common manifestation of childhood undernutrition worldwide. Children presenting with severe acute malnutrition (SAM) are often also severely stunted. We evaluated linear growth and its determinants after medically complicated SAM.

METHODS

We performed secondary analysis of clinical trial data (NCT00934492) from HIV-uninfected Kenyan children aged 2-59 months hospitalised with SAM. Outcome was change in height/length-for-age z-score (HAZ) between enrolment and 12 months later. Exposures were demographic, clinical, anthropometric characteristics and illness episodes during follow-up.

RESULTS

Among 1169 children with HAZ values at month 12 (66% of those in original trial), median (IQR) age 11 (7-17) months and mean (SD) HAZ -2.87 (1.6) at enrolment, there was no change in mean HAZ between enrolment and month 12: -0.006Z (95% CI -0.07 to 0.05Z). While 262 (23%) children experienced minimal HAZ change (within ±0.25 HAZ), 472 (40%) lost >0.25 and 435 (37%) gained >0.25 HAZ. After adjusting for regression to the mean, inpatient or outpatient episodes of diarrhoea and inpatient severe pneumonia during follow-up were associated with HAZ loss. Premature birth and not being cared by the biological parent were associated with HAZ gain. Increases in mid-upper arm circumference and weight-for-age were associated with HAZ gain and protected against HAZ loss. Increase in weight-for-height was not associated with HAZ gain but protected against HAZ loss. No threshold of weight gain preceding linear catch-up growth was observed.

CONCLUSIONS

Interventions to improve dietary quality and prevent illness over a longer period may provide opportunities to improve linear growth.

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

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

Follow-up between 6 and 24 months after discharge from treatment for severe acute malnutrition in children aged 6-59 months: A systematic review

BACKGROUND

Severe acute malnutrition (SAM) is a major global health problem affecting some 16.9 million children under five. Little is known about what happens to children 6-24 months post-discharge as this window often falls through the gap between studies on SFPs and those focusing on longer-term effects.

METHODS

A protocol was registered on PROSPERO (PROSPERO 2017:CRD42017065650). Embase, Global Health and MEDLINE In-Process and Non-Indexed Citations were systematically searched with terms related to SAM, nutritional intervention and follow-up between June and August 2017. Studies were selected if they included children who experienced an episode of SAM, received a therapeutic feeding intervention, were discharged as cured and presented any outcome from follow-up between 6-24 months later.

RESULTS

3,691 articles were retrieved from the search, 55 full-texts were screened and seven met the inclusion criteria. Loss-to-follow-up, mortality, relapse, morbidity and anthropometry were outcomes reported. Between 0.0% and 45.1% of cohorts were lost-to-follow-up. Of those discharged as nutritionally cured, mortality ranged from 0.06% to 10.4% at an average of 12 months post-discharge. Relapse was inconsistently defined, measured, and reported, ranging from 0% to 6.3%. Two studies reported improved weight-for-height z-scores, whilst three studies that reported height-for-age z-scores found either limited or no improvement.

CONCLUSIONS

Overall, there is a scarcity of studies that follow-up children 6-24 months post-discharge from SAM treatment. Limited data that exists suggest that children may exhibit sustained vulnerability even after achieving nutritional cure, including heightened mortality and morbidity risk and persistent stunting. Prospective cohort studies assessing a wider range of outcomes in children post-SAM treatment are a priority, as are intervention studies exploring how to improve post-SAM outcomes and identify high-risk children.

Progress of children with severe acute malnutrition in the malnutrition treatment centre rehabilitation program: evidence from a prospective study in Jharkhand, India

BACKGROUND

In Jharkhand, Malnutrition Treatment Centres (MTCs) have been established to provide care to children with severe acute malnutrition (SAM). The study examined the effects of facility- and community based care provided as part the MTC program on children with severe acute malnutrition.

METHOD

A cohort of 150 children were enrolled and interviewed by trained investigators at admission, discharge, and after two months on the completion of the community-based phase of the MTC program. Trained investigators collected data on diet, morbidity, anthropometry, and utilization of health and nutrition services.

RESULTS

We found no deaths among children attending the MTC program. Recovery was poor, and the majority of children demonstrated poor weight gain, with severe wasting and underweight reported in 52 and 83% of the children respectively at the completion of the community-based phase of the MTC program. The average weight gain in the MTC facility (3.8 ± 5.9 g/kg body weight/d) and after discharge (0.6 ± 2.1 g/kg body weight/d) was below recommended standards. 67% of the children consumed food that met less than 50% of the recommended energy and protein requirement. Children experienced high number of illness episodes after discharge: 68% children had coughs and cold, 40% had fever and 35% had diarrhoea. Multiple morbidities were common: 50% of children had two or more episodes of illness. Caregiver's exposure to MTC's health and nutrition education sessions and meetings with frontline workers did not improve feeding practices at home. The take-home ration amount distributed to children through the supplementary food program was inadequate to achieve growth benefits.

CONCLUSIONS

Recovery of children during and after the MTC program was suboptimal. This highlights the need for additional support to strengthen MTC program so that effective care to children can be provided.

Use of tuberculin skin test for assessment of immune recovery among previously malnourished children in Ethiopia

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.

Effects of unconditional cash transfers on the outcome of treatment for severe acute malnutrition (SAM): a cluster-randomised trial in the Democratic Republic of the Congo

BACKGROUND

Cash transfer programs (CTPs) aim to strengthen financial security for vulnerable households. This potentially enables improvements in diet, hygiene, health service access and investment in food production or income generation. The effect of CTPs on the outcome of children already severely malnourished is not well delineated. The objective of this study was to test whether CTPs will improve the outcome of children treated for severe acute malnutrition (SAM) in the Democratic Republic of the Congo over 6 months.

METHODS

We conducted a cluster-randomised controlled trial in children with uncomplicated SAM who received treatment according to the national protocol and counselling with or without a cash supplement of US$40 monthly for 6 months. Analyses were by intention to treat.

RESULTS

The hazard ratio of reaching full recovery from SAM was 35% higher in the intervention group than the control group (adjusted hazard ratio, 1.35, 95% confidence interval (CI) = 1.10 to 1.69, P = 0.007). The adjusted hazard ratios in the intervention group for relapse to moderate acute malnutrition (MAM) and SAM were 0.21 (95% CI = 0.11 to 0.41, P = 0.001) and 0.30 (95% CI = 0.16 to 0.58, P = 0.001) respectively. Non-response and defaulting were lower when the households received cash. All the nutritional outcomes in the intervention group were significantly better than those in the control group. After 6 months, 80% of cash-intervened children had re-gained their mid-upper arm circumference measurements and weight-for-height/length Z-scores and showed evidence of catch-up. Less than 40% of the control group had a fully successful outcome, with many deteriorating after discharge. There was a significant increase in diet diversity and food consumption scores for both groups from baseline; the increase was significantly greater in the intervention group than the control group.

CONCLUSIONS

CTPs can increase recovery from SAM and decrease default, non-response and relapse rates during and following treatment. Household developmental support is critical in food insecure areas to maximise the efficiency of SAM treatment programs.

Efficacy of three feeding regimens for home-based management of children with uncomplicated severe acute malnutrition: a randomised trial in India

OBJECTIVE

To assess the efficacy of ready-to-use therapeutic food (RUTF), centrally produced RUTF (RUTF-C) or locally prepared RUTF (RUTF-L) for home-based management of uncomplicated severe acute malnutrition (SAM) compared with micronutrient-enriched (augmented) energy-dense home-prepared foods (A-HPF, the comparison group).

METHODS

In an individually randomised multicentre trial, we enrolled 906 children aged 6-59 months with uncomplicated SAM. The children enrolled were randomised to receive RUTF-C, RUTF-L or A-HPF. We provided foods, counselling and feeding support until recovery or 16 weeks, whichever was earlier and measured outcomes weekly (treatment phase). We subsequently facilitated access to government nutrition services and measured outcomes once 16 weeks later (sustenance phase). The primary outcome was recovery during treatment phase (weight-for-height ≥-2 SD and absence of oedema of feet).

RESULTS

Recovery rates with RUTF-L, RUTF-C and A-HPF were 56.9%, 47.5% and 42.8%, respectively. The adjusted OR was 1.71 (95% CI 1.20 to 2.43; p=0.003) for RUTF-L and 1.28 (95% CI 0.90 to 1.82; p=0.164) for RUTF-C compared with A-HPF. Weight gain in the RUTF-L group was higher than in the A-HPF group (adjusted difference 0.90 g/kg/day, 95% CI 0.30 to 1.50; p=0.003). Time to recovery was shorter in both RUTF groups. Morbidity was high and similar across groups. At the end of the study, the proportion of children with weight-for-height Z-score (WHZ) >-2 was similar (adjusted OR 1.12, 95% CI 0.74 to 1.95; p=0.464), higher for moderate malnutrition (WHZ<-2 and ≥-3; adjusted OR 1.46, 95% CI 1.02 to 2.08; p=0.039), and lower for those with SAM (adjusted OR 0.58, 95% CI 0.40 to 0.85; p=0.005) in the RUTF-L when compared with the A-HPF group.

CONCLUSIONS

This first randomised trial comparing options for home management of uncomplicated SAM confirms that RUTF-L is more efficacious than A-HPF at home. Recovery rates were lower than in African studies, despite longer treatment and greater support for feeding.

Interventions to tackle malnutrition and its risk factors in children living in slums: a scoping review

CONTEXT

Children living in slums are at high risk of being malnourished. There are no published reviews on existing interventions promoting better nutrition for children living in slums and the risk factors for children's malnutrition. Improved understanding of the risk factors for malnutrition in slums communities and the impact of interventions on children's health can provide guidance to practitioners and decision-makers. The present review is designed to provide this information.

METHODS

The search included 30 electronic bibliographic databases and relevant eligible studies published up to December 2013.

RESULTS

The search located 1512 citations. Full text relevance screening was conducted on 226 studies and on abstracts for 16 studies. The final 58 unique studies included 22 on interventions and 38 on risk. All of the interventions were nutrition-specific, with nutritional intervention being the most dominant type. Seventy-three per cent of the interventions were assessed effective.

CONCLUSION

The findings stressed the gaps in knowledge in terms of quality assessment and programmatic recommendations to identify children who are the most at risk of malnutrition to appropriately target interventions. Finally, the review helped to inform a systematic review (Cochrane Systematic review protocol 2015) that will examine the impact of interventions on outcome measures.

Evaluation of a residential nutrition rehabilitation center in rural Bolivia: short-term effectiveness and follow-up results

BACKGROUND

Nutrition rehabilitation centers (NRCs) have shown mixed results in reducing morbidity and mortality among undernourished children in the developing world. Follow-up on children after leaving these programs remains undocumented.

OBJECTIVE

To assess the nutritional improvement of children attending the Centro de Rehabilitación Infantil Nutricional (CRIN), a residential NRC in rural Bolivia, from entrance to exit and to a household follow-up visit 1 month to 6 years later, and to identify factors associated with nutritional improvement.

METHODS

A retrospective analysis was conducted of clinical records collected by CRIN staff from 135 children under 3 years of age attending CRIN in rural Cochabamba, Bolivia, from 2003 to 2009, and of clinical records of household follow-up measurements on a subset of 26 children that were taken between 1 month and 6 years postexit. Nutritional status was evaluated by calculating z-scores for weight-for-height (WHZ), weight-for-age (WAZ), and height-for-age (HAZ). Children with z-scores < -2 were considered to be wasted, underweight, or stunted, respectively.

RESULTS

The prevalence of wasting decreased significantly, while the prevalence of stunting did not change significantly between entrance and exit from the program. From entrance to exit, the mean changes in WHZ (0.79) and WAZ (1.08) were statistically significant, while the mean change in HAZ (-0.02) was not significant. Linear regression analysis suggested that nutritional status and diarrhea at entrance had the greatest effect on WHZ and HAZ changes between entrance and exit. Children maintained their nutritional gains from the program between exit and follow-up and showed statistically significant improvement in WAZ (but not HAZ).

CONCLUSIONS

CRIN is effective at rehabilitating nutritional deficits associated with wasting, but not those associated with stunting.

Perspectives for integration into the local health system of community-based management of acute malnutrition in children under 5 years: a qualitative study in Bangladesh

BACKGROUND

Acute malnutrition is a major cause of death among under-five children in low- and middle-income countries. United Nations agencies recommend the integration of community-based management of acute malnutrition (CMAM) into the local health systems for sustainability. The objective of the study was to assess the preparedness of the health system to implement CMAM targeting children under-five years in two sub-districts of Bangladesh.

METHODS

The assessment was performed through direct observation of 44 health centres, individual interviews of seven policy makers, three donors, four health and nutrition implementing partners, 29 health workers, and review of secondary data. Assessment themes, derived from the WHO six Building Blocks, were nutrition governance, nutrition financing, health service delivery, human resources, equipment and supply, referral, monitoring and supervision mechanism. They were subdivided into 16 criteria. Findings were compared with CMAM operational recommendations according to WHO, Valid International and Food and Nutrition Technical Assistance guidelines.

RESULTS

The government of Bangladesh has developed inpatient and outpatient CMAM guidelines, and a policy offering free-of-charge health care for under-five children. Nutrition coordination was not under full government leadership. Most of funds (74%) dedicated to CMAM were provided by donors, for short-term interventions. Of the total 44 health centres assessed, 39 (88.6%) were active, among which 4 (10.2%) delivered inpatient services, 35 (89.8%) outpatient services, and 24 (61.5%) outreach services. These were regarded as opportunities to include CMAM activities. There were 48.9% vacant positions and the health workers were not trained for management of acute malnutrition. Equipment and supplies did not meet the operational recommendations for management of acute malnutrition.

CONCLUSION

Implementing CMAM through the health centres of both sub-districts would warrant progressive strengthening of the overall health system in the light of identified barriers. A short term strategy would consist of strengthening government coordination of nutrition interventions, exploring additional funding sources, equipping and supplying functional health centres, training health workers and actively involving community health workers to cope with health facility staff shortage. A mid-term strategy would consist of securing permanent funding for CMAM, rehabilitating non-functional health centres, attracting and retaining health workers in rural areas.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Evidence-based interventions for improvement of maternal and child nutrition: what can be done and at what cost?

Maternal undernutrition contributes to 800,000 neonatal deaths annually through small for gestational age births; stunting, wasting, and micronutrient deficiencies are estimated to underlie nearly 3·1 million child deaths annually. Progress has been made with many interventions implemented at scale and the evidence for effectiveness of nutrition interventions and delivery strategies has grown since The Lancet Series on Maternal and Child Undernutrition in 2008. We did a comprehensive update of interventions to address undernutrition and micronutrient deficiencies in women and children and used standard methods to assess emerging new evidence for delivery platforms. We modelled the effect on lives saved and cost of these interventions in the 34 countries that have 90% of the world's children with stunted growth. We also examined the effect of various delivery platforms and delivery options using community health workers to engage poor populations and promote behaviour change, access and uptake of interventions. Our analysis suggests the current total of deaths in children younger than 5 years can be reduced by 15% if populations can access ten evidence-based nutrition interventions at 90% coverage. Additionally, access to and uptake of iodised salt can alleviate iodine deficiency and improve health outcomes. Accelerated gains are possible and about a fifth of the existing burden of stunting can be averted using these approaches, if access is improved in this way. The estimated total additional annual cost involved for scaling up access to these ten direct nutrition interventions in the 34 focus countries is Int$9·6 billion per year. Continued investments in nutrition-specific interventions to avert maternal and child undernutrition and micronutrient deficiencies through community engagement and delivery strategies that can reach poor segments of the population at greatest risk can make a great difference. If this improved access is linked to nutrition-sensitive approaches--ie, women's empowerment, agriculture, food systems, education, employment, social protection, and safety nets--they can greatly accelerate progress in countries with the highest burden of maternal and child undernutrition and mortality.

A study to evaluate the effect of nutritional intervention measures on admitted children in selected nutrition rehabilitation centers of indore and ujjain divisions of the state of madhya pradesh (India)

Background:

The state of Madhya Pradesh has 1.3 million severely malnourished children. Nutrition rehabilitation centers (NRCs) were started in the state to control severe malnutrition and decrease the prevalence of severe malnourished children to less than 1% among children aged 1–5 years.

Materials and Methods:

The present study was conducted from November 2008 to October 2009; 100 children admitted to seven different NRCs in Indore and Ujjain divisions of Madhya Pradesh were observed during their stay at NRCs and the follow-up period to analyze the effect of interventional measures on select anthropometric indicators. Mothers of the children were interviewed on health issues and therapeutic feeding practices at the NRCs using a predesigned and pretested interview schedule.

Results:

The study group consisted of 48 boys and 52 girls; 60% were between 13 and 36 months of age. 93 children were analyzed for anthropometric indicators following a dropout rate of 7%. A statistically significant difference was obtained between the weight of children at admission and discharge (t=14.552, P<0.001); difference of mid upper arm circumference (MUAC) at admission and discharge was statistically significant (t=9.548, P<0.001). The average weight gain during the stay at the centers was 9.25 ± 5.89 g/kg/day. Though the number of severe malnourished children decreased from 85 to 43 following the stay at NRCs (χ² = 44.195, P<0.001); 48.78% of the children lost weight within 15 days of discharge from the NRCs. Dropout rates of 9.89%, 23.07%, 42.65%, and 61.76% for the study group were obtained during the follow-up period of 6 months for the four follow-up visits conducted 15 days, 1, 3, and 6 months after discharge. The mothers of the children lacked adequate information on health issues and composition and preparation of therapeutic diets at the centers.

Conclusion:

The NRCs were effective in improving the condition of admitted children, but the effects were not sustained following discharge due to high drop-out rate and lack of adequate parental awareness. There is an urgent need to link these centers with community-based models for follow-up and improve health education measures to maintain the gains achieved.

A follow-up experience of 6 months after treatment of children with severe acute malnutrition in Dhaka, Bangladesh

AIM

As there is lack of information about what happens to children after recovery from severe acute malnutrition (SAM), we report their relapse, morbidity, mortality and referral during follow-up period.

METHODS

From February 2001 to November 2003, 180 children completing acute and nutrition rehabilitation (NR) phases of protocolized management were advised for 6-months follow-up. The mean (SD) age was 12 (5) months, 55% were infants, 53% were male and 68% were breast-fed.

RESULTS

The follow-up compliance rate dropped from 91% at first to 49% at tenth visit. The common morbidities following discharge included fever (26%), cough (24%) and diarrhoea (20%). Successful follow-up done in 124 children [68.9% (95% CI 61.8-75.2%)], partial follow-up in 45 [25% (95% CI 19.2-31.8%)], relapse in 32 [17.8% (95% CI 12.9-24%)] and 5 [2.8% (95% CI 1.2-6.3%)] died.

CONCLUSION

Our findings highlight need for follow-up as part of overall management of SAM and recommend an effective community follow-up.

[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.

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.

Critical appraisal of the management of severe malnutrition: 1. Epidemiology and treatment guidelines

Hospital case-fatality rates for severe malnutrition in the developing world remain high, particularly in Africa where they have not changed much over recent decades. In an effort to improve case management, WHO has developed treatment guidelines. The aim of this review is to critically appraise the evidence for the guidelines and review important recent advances in the management of severe malnutrition. We conclude that not only is the evidence base deficient, but also the external generalisability of even good-quality studies is seriously compromised by the great variability in clinical practice between regions and types of health facilities in the developing world, which is much greater than between developed countries. The diagnosis of severe wasting is complicated by the dramatic change in reference standards (from CDC/WHO 1978 to CDC 2000 in EpiNut) and also by difficulties in accurate measurement of length. Although following treatment guidelines has resulted in improved outcomes, there is evidence against the statement that case-fatality rates (particularly in African hospitals) can be reduced below 5% and that higher rates are proof of poor practice, because there is wide variation in severity of illness factors. The practice of prolonged hospital treatment of severe malnutrition until wasting and/or oedema has resolved is being replaced by shorter hospital stays combined with outpatient or community follow-up because of advances in dietary management outside of hospital.

Outpatient care for severely malnourished children in emergency relief programmes: a retrospective cohort study

BACKGROUND

In emergency nutritional relief programmes, therapeutic feeding centres are the accepted intervention for the treatment of severely malnourished people. These centres often cannot treat all the people requiring care. Consequently, coverage of therapeutic feeding centre programmes can be low, reducing their effectiveness. We aimed to assess the effectiveness of outpatient treatment for severe malnutrition in an emergency relief programme.

METHODS

We did a retrospective cohort study in an outpatient therapeutic feeding programme in Ethiopia from September, 2000, to January, 2001. We assessed clinical records for 170 children aged 6-120 months. The children had either marasmus, kwashiorkor, or marasmic kwashiorkor. Outcomes were mortality, default from programme, discharge from programme, rate of weight gain, and length of stay in programme.

FINDINGS

144 (85%) patients recovered, seven (4%) died, 11 (6%) were transferred, and eight (5%) defaulted. Median time to discharge was 42 days (IQR 28-56), days to death 14 (7-26), and days to default 14 (7-28). Median rate of weight gain was 3.16 g kg(-1) x day(-1) (1.86-5.60). In patients who recovered, median rates of weight gain were 4.80 g kg(-1) day(-1) (2.95-8.07) for marasmic patients, 4.03 g x kg(-1) x day(-1) (2.68-4.29) for marasmic kwashiorkor patients, and 2.70 g x kg(-1) x day(-1) (0.00-4.76) for kwashiorkor patients.

INTERPRETATION

Outpatient treatment exceeded internationally accepted minimum standards for recovery, default, and mortality rates. Time spent in the programme and rates of weight gain did not meet these standards. Outpatient care could provide a complementary treatment strategy to therapeutic feeding centres. Further research should compare the effectiveness of outpatient and centre-based treatment of severe malnutrition in emergency nutritional interventions.

Changing the way we address severe malnutrition during famine

This year, yet again, saw widespread food insecurity and famine across the horn of Africa. Again, humanitarian agencies set up operations to implement various relief programmes. Nutritional interventions included general ration distribution to the whole of an affected population; blanket supplementary feeding to all members of an identified risk group; and targeted dry supplementary feeding centres for moderately malnourished and therapeutic feeding centres for the severely malnourished. As is usual in emergencies, many of the therapeutic feeding centres were hard to set up and did not achieve an adequate coverage of all the severely malnourished. This combination of delays and low coverage meant that many therapeutic feeding centres achieved little overall impact on mortality. I believe that the present focus on therapeutic feeding centres as the sole mode of treating severely malnourished people during famine is inappropriate and often counter-productive. A new concept of community-based therapeutic care is necessary to complement therapeutic feeding centres' interventions if famine relief programmes are to address the plight of the severely malnourished in an efficient and effective manner. During an emergency, the community-based therapeutic care approach could quickly provide good coverage and appropriate treatment for large numbers of severely malnourished people. The principles behind community-based therapeutic care are, however, developmental, empowering communities to cope more effectively with crisis and with transition back to normality. This is very different to the therapeutic feeding centres' approach that disempowers communities, requires very large amounts of external staff and resources, and undermines the infrastructure. Although emergency community-based therapeutic care programmes could be large-scale and implemented quickly, they could also evolve into developmental Hearth model nutritional programmes without changing their conceptual basis. Conversely, Hearth programmes, although largely sustainable, could in times of crisis quickly scale-up into rapid effective emergency interventions. Creating such a continuum between emergency and developmental approaches has long been a holy grail of humanitarianism.

Linear and knemometric growth in the early phase of rehabilitation from severe malnutrition

The relationship between ponderal, linear and lower leg growth in children recovering from severe malnutrition remains unclear. We report on the early growth of 141 severely malnourished Bangladeshi children aged 6 to 36 months of age who were followed for 90 d. Mean (sd) weight for height (WHZ) and height for age (HAZ) catch-up growth z scores over the 90 d were 1.6 (0.85) and 0.47 (0.325) respectively. Mean (sd) lower leg length growth was 10.35 (4.5) mm. Change in HAZ was significantly associated with initial WHZ, but linear growth occurred in the presence of severe wasting and no threshold WHZ score was identified. Lower leg length gain correlated throughout with ponderal indices but with change in HAZ score only after day 45. Only initial WHZ score and maternal height predicted for linear growth and only accounted for 20 % of total variance. We conclude that linear growth occurs early in severely malnourished children but that knemometry behaves as a ponderal index acutely.

New concepts on nutritional management of severe malnutrition: the role of protein

Current guidelines for the management of severe malnutrition are mainly based on new concepts regarding the causes of malnutrition and on advances in our knowledge of the physiological roles of micronutrients. In contrast to the early 'protein dogma', there is a growing body of evidence that severely malnourished children are unable to tolerate large amounts of dietary protein during the initial phase of treatment. Similarly, great caution must be exercised to avoid excessive supply of iron and sodium in the diet, while keeping energy intake at maintenance levels during early treatment. Because severely malnourished children require special micronutrients, a mineral-vitamin mix is added to the milk-based formula diets, which are specially designed for the initial treatment and the rehabilitation phase. To further improve nutritional rehabilitation and reduce cases of relapse, 'ready-to-use therapeutic food' and 'ready-to-eat nutritious supplements' with relatively low protein (10% protein calories) and high fat content (54-59% lipidic calories) have been developed. Although current dietary recommendations do not differentiate between oedematous and nonoedematous forms of malnutrition or between adults and children, there are indications that further clarification is still needed for applying dietary measures for specific target groups.
