[Factors associated with malnutrition in infants with congenital heart disease within one year after surgery].

Objective: To explore the risk factors of malnutrition in infants with congenital heart disease within one year after surgery. Methods: This retrospective cohort study selected 502 infants with congenital heart disease who underwent surgical treatment in Guangzhou Women and Children's Medical Center from February 2018 to January 2019. Their basic information and clinical data were analyzed, and their nutrition status after the surgery was followed up by questionnaire survey. Weight-for-age Z score (WAZ)≤-2 one year after operation was defined as malnutrition group, and WAZ>-2 was non-malnutrition group. The perioperative indicators and complementary food advancement were compared between the two groups by chi-square test, t-test, and Kruskal-Wallis test. The risk factors of malnutrition were analyzed by Logistic regression. Results: A total of 502 infants were selected, including 301 males and 201 females, with the age of 4.1 (2.0, 6.8) months. There were 90 cases in malnutrition group and 412 cases in non-malnutrition group. The body length and weight at birth in the malnutrition group were lower than those in the non-malnutrition group ((47.8±3.8) vs. (49.3±2.5) cm, (2.7±0.6) vs.(3.0±0.5) kg, both P<0.001). The proportion of paternal high school education or above and the proportion of family per capita income of 5 000 yuan or above in the malnutrition group were lower than those in the non-malnutrition group ((18.9% (17/90) vs. 30.8% (127/412), 18.9% (17/90) vs. 33.7% (139/412), both P<0.05). Compared to the non-malnutrition group, the proportion of complex congenital heart disease in the malnutrition group was higher (62.2% (56/90) vs. 47.3% (195/412), P<0.05). The postoperative mechanical ventilation time, postoperative intensive care unit (ICU) stay time, postoperative hospital stay, total length of ICU stay and total hospital stay in the malnutrition group were significantly longer than those in non-malnutrition group (all P<0.05). The proportion of egg and fish supplementation over 2 times/week within one year after the surgery was also lower in the malnutrition group (both P<0.05). Logistic regression analysis showed that mother's weight at delivery (OR=0.95,95%CI 0.91-0.99), the pre-operative WAZ≤-2 (OR=6.04, 95%CI 3.13-11.65), the complexity of the cardiac disease (OR=2.23, 95%CI 1.22-4.06), the hospital stay after the surgery over 14 days (OR=2.61, 95%CI 1.30-5.26), the types of complementary food<4 (OR=2.57, 95%CI 1.39-4.76), and the frequency of meat and fish<2 times/week (OR=2.11, 95%CI 1.13-3.93) were the risk factors associated with malnutrition within one year after the surgery. Conclusion: Mother's weight at delivery pre-operative nutritional status, complexity of cardiac disease, postoperative hospital stay, types of daily supplements and frequency of fish are risk factors associated with malnutrition within one year after surgery in children with congenital heart disease.

Risk factors for early occurrence of malnutrition in infants with severe congenital heart disease.

To identify the risk factors of early occurrence of malnutrition in infants with severe congenital heart disease (CHD) during their first year of life. Retrospective longitudinal multicenter study carried out from January 2014 to December 2020 in two tertiary care CHD centers. Four CHD hemodynamic groups were identified. Malnutrition was defined by a Waterlow score under 80% and/or underweight under -2 standard deviations. A total of 216 infants with a severe CHD, e.g., requiring cardiac surgery, cardiac catheterization, or hospitalization for heart failure during their first year of life, were included in the study. Malnutrition was observed among 43% of the cohort, with the highest prevalence in infants with increased pulmonary blood flow (71%) compared to the other hemodynamic groups (p < 0.001). In multivariate analysis, low birthweight (OR 0.62, 95% CI 0.44-0.89, p = 0.009), CHD with increased pulmonary blood flow (OR 4.80, 95% CI 1.42-16.20, p = 0.08), heart failure (OR 9.26, 95% CI 4.04-21.25, p < 0.001), and the number of hospitalizations (OR 1.35, 95% CI 1.08 l-1.69, p = 0.009) during the first year of life were associated with malnutrition (AUC 0.85, 95% CI 0.79-0.90).  Conclusions: In infants with a severe CHD, early occurrence of malnutrition during the first year of life affected a high proportion of subjects. CHD with increased pulmonary blood flow, low birthweight, heart failure, and repeated hospitalizations were risk factors for malnutrition. Further studies are required to identify optimal nutritional support in this population. What is Known: • Malnutrition is a known morbidity and mortality factor in children with severe congenital heart disease. What is New: • Early occurrence of malnutrition during the first year of life in infant severe congenital heart disease (CHD) was high (43%). • CHD with increased pulmonary blood flow, low birthweight, heart failure, and repeated hospitalizations during the first year of life were risk factors for malnutrition.

Conclusion: Mother's weight at delivery pre-operative nutritional status, complexity of cardiac disease, postoperative hospital stay, types of daily supplements and frequency of fish are risk factors associated with malnutrition within one year after surgery in children with congenital heart disease.

Azithromycin versus Amoxicillin and Malarial Parasitemia among Children with Uncomplicated Severe Acute Malnutrition: A Randomized Controlled Trial.

Antibiotics are recommended by the WHO as part of the management of uncomplicated severe acute malnutrition in children. We evaluated whether azithromycin, an antibiotic with antimalarial properties, improved malarial parasitemia outcomes in children with severe acute malnutrition compared with amoxicillin, an antibiotic commonly used for severe acute malnutrition that does not have antimalarial properties. Total of 301 children were randomized (1:1) to a single oral dose of azithromycin or a 7-day course of amoxicillin and followed for 8 weeks. We found no significant evidence that children receiving azithromycin had improved parasitemia outcomes relative to amoxicillin. Although azithromycin may have advantages over amoxicillin in terms of dosing and administration for uncomplicated severe acute malnutrition, it may not yield additional benefit for malaria outcomes.

Use of TaqMan Array Cards to investigate the aetiological agents of diarrhoea among young infants with severe acute malnutrition.

OBJECTIVE: Studies involving less sensitive conventional microscopy and culture-based approaches have identified distinct differences in diarrhoeal aetiology in childhood malnutrition. Our study involved the use of an advanced molecular biology technique, the TaqMan Array Cards (TAC), to elucidate the diarrhoeal aetiology among young infants with severe acute malnutrition (SAM). METHOD: A total of 113 faecal samples was collected from SAM infants, aged 2-6 months, upon admission to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) with complications of diarrhoea and related comorbidities. We used TAC for the detection of 29 different diarrhoeal enteropathogens from a single faecal sample. For comparison, we also analysed 25 diarrhoeal samples from well-nourished infants of similar age. RESULTS: Higher odds of detection of all bacterial enteropathogens were associated with diarrhoea among SAM infants. In particular, the detection of Aeromonas sp (aOR: 25.7, p = 0.011), Campylobacter sp (aOR: 9.6, p < 0.01) and ETEC (aOR: 5.2, p = 0.022) was significantly associated with diarrhoea among SAM infants in comparison to well-nourished infants. 80% higher odds of detection of rotavirus and norovirus GII were associated with diarrhoea among well-nourished infants in comparison to SAM infants (aOR: 0.2, p < 0.05). CONCLUSION: Our study findings demonstrate a difference in diarrhoeal aetiology among SAM and well-nourished young infants, which may be useful in providing an evidence-based logic for possible revision of treatment guidelines for treatment of young diarrhoeal infants with SAM in the early management of the menace of antimicrobial resistance.

Duodenal Microbiota in Stunted Undernourished Children with Enteropathy.

BACKGROUND: Environmental enteric dysfunction (EED) is an enigmatic disorder of the small intestine that is postulated to play a role in childhood undernutrition, a pressing global health problem. Defining the incidence of this disorder, its pathophysiological features, and its contribution to impaired linear and ponderal growth has been hampered by the difficulty in directly sampling the small intestinal mucosa and microbial community (microbiota). METHODS: In this study, among 110 young children (mean age, 18 months) with linear growth stunting who were living in an urban slum in Dhaka, Bangladesh, and had not benefited from a nutritional intervention, we performed endoscopy in 80 children who had biopsy-confirmed EED and available plasma and duodenal samples. We quantified the levels of 4077 plasma proteins and 2619 proteins in duodenal biopsy samples obtained from these children. The levels of bacterial strains in microbiota recovered from duodenal aspirate from each child were determined with the use of culture-independent methods. In addition, we obtained 21 plasma samples and 27 fecal samples from age-matched healthy children living in the same area. Young germ-free mice that had been fed a Bangladeshi diet were colonized with bacterial strains cultured from the duodenal aspirates. RESULTS: Of the bacterial strains that were obtained from the children, the absolute levels of a shared group of 14 taxa (which are not typically classified as enteropathogens) were negatively correlated with linear growth (length-for-age z score, r = -0.49; P = 0.003) and positively correlated with duodenal proteins involved in immunoinflammatory responses. The representation of these 14 duodenal taxa in fecal microbiota was significantly different from that in samples obtained from healthy children (P<0.001 by permutational multivariate analysis of variance). Enteropathy of the small intestine developed in gnotobiotic mice that had been colonized with cultured duodenal strains obtained from children with EED. CONCLUSIONS: These results provide support for a causal relationship between growth stunting and components of the small intestinal microbiota and enteropathy and offer a rationale for developing therapies that target these microbial contributions to EED.

Refeeding Syndrome with Hypoglycemia in a Severely Malnourished Infant.

A 5-mo-old severely malnourished 3.5 kg boy was brought to the emergency department with hypoglycemia, bradycardia, bradypnea, and hypothermia. His findings were likely due to severe malnutrition secondary to parental neglect. Resuscitation with dextrose containing intravenous fluids was promptly started. On day 2 of admission, refeeding was initiated. From that time, he had multiple hypoglycemic episodes along with hypophosphatemia, hypomagnesemia, and hypokalemia. Hypoglycemia was associated with the initiation of enteral feeding and an increase in calories and amounts of enteral feeding. Hypoglycemia associated with refeeding syndrome in infant has not been previously reported.

Not All Stridor Is Croup.

BACKGROUND: Emergency providers often attribute stridor to croup in pediatric patients. However, even in children who are having other symptoms of a viral etiology, several other causes need to be considered. CASE: A 6-month-old term male without significant past medical history presented to the emergency department with stridor with likely underlying laryngospasm. He was initially ascribed the diagnosis of croup and was discharged home after receiving steroids and racemic epinephrine. However, he returned hours later after a seizure event at home. A thorough evaluation revealed an ionized calcium of 0.49 mmol/L, and further history revealed the patient was being fed a coconut water-based homemade solution for several months. He was subsequently found to have rickets and delay in milestone achievement. Awareness of hypocalcemia as a possible cause of laryngospasm is important because of the potential life-threatening effects of critically low calcium. Hypocalcemia should be included in the differential diagnosis of any child who presents with stridor, especially if lacking other symptoms of a viral illness.

Factors influencing childhood anaemia in Bangladesh: a two level logistic regression analysis.

BACKGROUND: Anemia is not only a major public health problem among children in developing countries, it is also an important predictor for their future growth and development. The objective of this study was to identify possible factors associated with anemia among pre-school children in Bangladesh after removing a cluster effect of the population, and to determine the prevalence of this condition. METHODS: Data for this study was extracted from the 2011 Bangladesh Demographic and Health Survey (BDHS-2011). In this survey, data was collected using a two-stage stratified cluster sampling approach. The chi-square test and a two-level logistic regression model were used for further analysis. RESULTS: Data from 2231 children aged 6-59 months were included for analysis. The prevalence of child anemia was noted to be 52.10%. Among these anemic children, 48.40% where from urban environment and 53.90% were from rural areas. The prevalence of mild, moderate and severe anemia among children was 57.10, 41.40 and 1.50% respectively. The two-level logistic regression model revealed that the following factors were associated with childhood anemia: children of anemic mothers (p < 0.01), undernourished children (p < 0.05), younger children (age < 2 years) (p < 0.01) and children from poor family (p < 0.05). Lastly, anemia was more common among children living in Barisal and Rangpur divisions compared to those from Dhaka division (p < 0.01), and among non-Muslims than Muslim (p < 0.05). CONCLUSIONS: Our study showed that prevalence of anemia among pre-school children in Bangladesh was very high (52.10%). We noted that young children of anemic mothers, from poor families, and being undernourished were at higher risk of developing anemia. Since most of these risk factors were related to socioeconomic conditions, they were potentially modifiable. Therefore, our findings may be useful for the health authorities to identify children at risk for remedial action and to plan for preventive measures.

Short stature among children undergoing cardiac surgery for congenital heart defects. / Talla baja en niños con defectos cardíacos congénitos sometidos a cirugía cardíaca.

Introduction: Children with congenital heart diseases (CHDs) suffer from malnutrition because of nutritional deficiencies, being short stature the possible long-term consequence. Objective: To describe the presence of short stature among children undergoing cardiac surgery for CHDs. Population and methods: Retrospective study. Children undergoing cardiac surgery with cardiopulmonary bypass pump between 2009 and 2013 were included. Preterm infants, carriers of genetic syndromes or other disease with nutritional compromise were excluded. Demographic data, type of CHD, admission surgery and anthropometric assessment using the WHO standards were studied. Short stature was defined as lenght/height for age Z score < -2 standard deviations, by sex. Results: A total of 640 children were studied; 361 (56.4 %) were boys; median age: 8 months (IQR: 1.9; 34.6); 66 children underwent > 1 surgery; 27 of them (40.9 %) had hypoplasia of the left ventricle. There were 358 (55.9 %) infants with cyanotic CHDs, 196 (30.6 %) with univentricular physiology. The median HAZ was -0.9 (IQR: -1.9; -0.1); 135 (21.1 %) had a short stature, 11 % of newborn infants and 24.1 % of older than one month old. A higher frequency of short stature was observed in 4 out of 6 children who underwent complete repair of the atrioventricular canal, in 15 out of 39 infants with repair of tetralogy of Fallot, in 8 out of 25 infants with hypoplasia of the left ventricle subjected to Glenn procedure, and in 34 out of 103 with closure of the ventricular septal defect. No association or statistically significant difference was found between short stature and cyanosis or univentricular physiology. Conclusions: There is a high frequency of short stature among children with CHDs, with differences according to the type of CHD and cardiac surgery performed.

Prediction of uncuffed tracheal tube sizes in children and infants using age/weight-based formulae: A retrospective cross-sectional study.

INTRODUCTION: The age-based formula is commonly used to predict tracheal tube (TT) sizes although its inaccuracy has been reported to reach as high as 60%. We aim to determine a practical formula using age in months and weight in kilograms to predict uncuffed tracheal tube (TT) size in children and infants. METHODS: A retrospective cross-sectional study was conducted on data obtained from a prospective study on children aged less than 9 years who came for elective surgery and received general anesthesia with oroendotracheal tube intubation at Songklanagarind Hospital between September 2008 and December 2012. The uncuffed TT sizes were based on the age-based formulae and the discretion of the attending anesthesiologist. The age (in months), weight (in kg), and final TT size were measured. Univariate and multivariate linear regression analyses were used to find potential predictors of final uncuffed TT size and therefore the best formula. The correlation coefficient (r) for each model was calculated. The kappa statistic was used to measure the agreement between predicted and actual TT size. RESULTS: A total of 668 patients were recruited. The age/weight formulae for infants aged ≤12 months and children aged >12 months were 3.15 + (age [months] × 0.05) + (weight [kg] × 0.05) with r value of 0.75 (n = 216) and 3.83 + (age [months] × 0.017) + (weight [kg] × 0.017) with r value of 0.85 (n = 452), respectively. The formulae correctly predicted 69.0% and 65.0% of actual TT sizes for infants and children, respectively (both p < 0.001). The formulae for malnourished infants and children whose weights were less than the 3rd percentile for age were 2.70 + (weight [kg] × 0.21) (n = 43) and 3.59 + (age [months] × 0.012) + (weight [kg] × 0.056) (n = 105) with r values of 0.81 and 0.87, respectively. CONCLUSION: The age/weight formula can be used to estimate TT size in infants and children. In failure to thrive children, our formula for malnourished children and infants provided high correlation with final TT sizes.

Immune Activation and Microbial Translocation Markers in HIV-Exposed Uninfected Malawian Infants in the First Year of Life.

BACKGROUND: HIV-exposed uninfected (HEU) infants show a high rate of morbidity. We aimed to investigate on biomarkers of immune activation/microbial translocation in HEU infants, evaluating the impact that infections/malnutrition can have on biomarker levels during the first year of life. METHODS: Clinical data of 72 Malawian infants were recorded monthly and correlated with levels of soluble CD14 (sCD14), lipopolysaccharide-binding protein (LBP) and intestinal fatty acid-binding protein (I-FABP), analyzed longitudinally. RESULTS: Levels of sCD14 and LBP showed a significant age-related increase. Higher levels of LBP (19.4 vs. 15.2 µg/ml) were associated with stunting, affecting 30% of the infants. The association remained statistically significant after adjusting for cytomegalovirus acquisition, malaria and respiratory infections (p = 0.031). I-FABP levels were significantly increased in infants experiencing gastrointestinal infections (1442.8 vs. 860.0 pg/ml, p = 0.018). CONCLUSION: We provide evidence that stunting is associated with an enhanced inflammatory response to microbial products in HEU children, suggesting that malnutrition status should be taken into consideration to better understand the alteration of the immune profile of HEU infants living in poor socioeconomic settings.

[Effectiveness and cost of management of severe acute malnutrition with complications in Kaya, Burkina Faso]. / Performance et coût de la prise en charge de la malnutrition aiguë sévère avec complications à Kaya, Burkina Faso.

INTRODUCTION: The consequences of severe acute malnutrition are measured in terms of health and survival, but also of cognitive development, its productivity and the overall national economy. Its management requires enormous financial resources. The purpose of this study was to assess the effectiveness of treating severe acute malnutrition versus cost of treatment of severe acute malnutrition in children. METHODS: We conducted a retrospective study of 199 children aged 0-59 months admitted to the Centre for Nutritional Recovery and Education in Kaya, Burkina Faso, from January to December 2014. The cost of treatment, the length of stay in the Centre for Nutritional Recovery and Education, daily weight gain and the speed of recovery were analyzed based on the standards calculation methods. Mann-Whitney test and Kruskall-Wallis test were used to compare the medians (0.05 threshold). RESULTS: As expected, children aged 6-23 months were the most affected (51.8%) and acute respiratory infections were the most associated diseases (57.9%). The median length of stay in the Centre for Nutritional Recovery and Education was 9.0 (7.0-13.0) days, the mean speed of recovery was 100.0 (65.8 - 143.3) g/day and the average daily weight gain was 18.1 (11.6 - 27.7) g/kg/day. The average cost of treatment in a malnourished child is estimated to be 15 715,3 FCFA (25.2 USD). CONCLUSION: The cost of treatment is hardly affordable by the parents of malnourished children; hence the necessity for government and development partners interventions.

Evaluating interventions to improve child nutrition in Eastern Democratic Republic of Congo.

OBJECTIVE: The prevention of malnutrition in children under two approach (PM2A), women's empowerment and agricultural interventions have not been widely evaluated in relation to child diet and nutrition outcomes. The present study evaluated the effectiveness of PM2A, women's empowerment groups (WEG), farmer field schools (FFS) and farmer-to-farmer training (F2F). DESIGN: Community-matched quasi-experimental design; outcome measures included children's dietary diversity, stunting and underweight. SETTING: Communities in South Kivu, Democratic Republic of the Congo.ParticipantsA total of 1312 children from 1113 households. RESULTS: Achievement of minimum dietary diversity ranged from 22·9 to 39·7 % and was significantly greater in the PM2A and FFS groups (P<0·05 for both comparisons). Fewer than 7·6 and 5·8 % of children in any group met minimum meal frequency and acceptable diet targets; only the PM2A group differed significantly from controls (P<0·05 for both comparisons). The endline stunting prevalence ranged from 54·7 % (PM2A) to 69·1 % (F2F) and underweight prevalence from 22·3 % (FFS) to 34·4 % (F2F). No significant differences were found between intervention groups and controls for nutrition measures; however, lower prevalences of stunting (PM2A, -4 %) and underweight (PM2A and FFS, -7 %) suggest potential impact on nutrition outcomes. CONCLUSIONS: Children in the PM2A and FFS groups had better child diet measures and nutrition outcomes with the best results among PM2A beneficiaries. Interventions that address multiple aspects nutrition education, health, ration provision and income generation may be more effective in improving child diet and nutrition in resource-poor settings than stand-alone approaches.

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.

Investigating Mediators of the Poor Pneumonia Outcomes of Human Immunodeficiency Virus-Exposed but Uninfected Children.

BACKGROUND: Human immunodeficiency virus-exposed but uninfected (HIV-EU) children have a higher mortality rate than the children of HIV-negative mothers (HIV-unexposed). Causal mediators of the poor health outcomes of HIV-EU children remain poorly defined. METHODS: We conducted a hospital-based prospective cohort study of children aged 1 to 23 months with clinically defined pneumonia. The children were recruited at a referral hospital in Gaborone, Botswana, between April 2012 and June 2016. The primary outcome, treatment failure at 48 hours, was assessed by an investigator blinded to the children's HIV-exposure status. We examined associations between HIV exposure and pneumonia outcomes in HIV-uninfected children. We next determined whether the effect of HIV exposure on outcomes was mediated by low-birth-weight status, nonbreastfeeding, malnutrition, in utero exposure to combination antiretroviral therapy, or pneumonia severity. RESULTS: A total of 352 HIV-uninfected children were included in these analyses, including 245 (70%) HIV-unexposed and 107 (30%) HIV-EU children. Their median age was 7.4 months, and 57% were male. Treatment failure occurred in 111 (32%) children, and 19 (5.4%) children died. HIV-EU children were more likely to fail treatment (risk ratio [RR], 1.57 [95% confidence interval (CI), 1.19-2.07]; P = .002) and had a higher in-hospital mortality rate (RR, 4.50 [95% CI, 1.86-10.85]; P = .001) than HIV-unexposed children. Nonbreastfeeding mediated 47% of the effect of HIV exposure on the risk of in-hospital death. CONCLUSIONS: HIV-EU children have worse pneumonia outcomes than HIV-unexposed children. Nonbreastfeeding mediates nearly half of the effect of HIV exposure on pneumonia mortality. Our findings provide additional evidence for a mortality benefit of breastfeeding by HIV-EU children.

Is chronic malnutrition associated with an increase in malaria incidence? A cohort study in children aged under 5 years in rural Gambia.

BACKGROUND: Malnutrition is common in children in sub-Saharan Africa and is thought to increase the risk of infectious diseases, including malaria. The relationship between malnutrition and malaria was examined in a cohort of 6-59 month-old children in rural Gambia, in an area of seasonal malaria transmission. The study used data from a clinical trial in which a cohort of children was established and followed for clinical malaria during the 2011 transmission season. A cross-sectional survey to determine the prevalence of malaria and anaemia, and measure the height and weight of these children was carried out at the beginning and end of the transmission season. Standard anthropometric indices (stunting, wasting and underweight) were calculated using z-scores. RESULTS: At the beginning of the transmission season, 31.7% of children were stunted, 10.8% wasted and 24.8% underweight. Stunting was more common in Fula children than other ethnicities and in children from traditionally constructed houses compared to more modern houses. Stunted children and underweight children were significantly more likely to have mild or moderate anaemia. During the transmission season, 13.7% of children had at least one episode of clinical malaria. There was no association between stunting and malaria incidence (odds ratio = 0.79, 95% CI: 0.60-1.05). Malaria was not associated with differences in weight or height gain. CONCLUSIONS: Chronic malnutrition remains a problem in rural Gambia, particularly among the poor and Fula ethnic group, but it was not associated with an increased risk of malaria.
