RESUMO

INTRODUCTION: Diarrhoea is one of the leading causes of under-5 childhood mortality and accounts for 8% of 5.4 million global under-5 deaths. In severely malnourished children, diarrhoea progresses to shock, where the risk of mortality is even higher. At icddr,b Dhaka Hospital, the fatality rate is as high as 69% in children with severe malnutrition and fluid refractory septic shock. To date, no study has evaluated systematically the effects of inotrope or vasopressor or blood transfusion in children with dehydrating diarrhoea (eg, in cholera) and severe acute malnutrition (SAM) or severe underweight who are in shock and unresponsive to WHO-recommended fluid therapy. To reduce the mortality of severely malnourished children presenting with diarrhoea and fluid refractory shock, we aim to compare the efficacy of blood transfusion, dopamine and epinephrine in fluid refractory shock in children who do not respond to WHO-recommended fluid resuscitation. METHODS AND ANALYSIS: In this randomised, three-arm, controlled, non-masked clinical trial in children 1-59 months old with SAM or severe underweight and fluid refractory shock, we will compare the efficacy of dopamine or epinephrine administration versus blood transfusion in children who failed to respond to WHO-recommended fluid resuscitation. The primary outcome variable is the case fatality rate. The effect of the intervention will be assessed by performing an intention-to-treat analysis. Recruitment and data collection began in July 2021 and are now ongoing. Results are expected by May 2023. ETHICS AND DISSEMINATION: This study has been approved by the icddr,b Institutional Review Board. We adhere to the 'Declaration of Helsinki' (2000), guidelines for Good Clinical Practice. Before enrolment, we collect signed informed consent from the parents or caregivers of the children. We will publish the results in a peer-reviewed journal and will arrange a dissemination seminar. TRIAL REGISTRATION NUMBER: NCT04750070.

RESUMO

Two emerging biomarkers of environmental enteric dysfunction (EED) include plasma citrulline (CIT), and the kynurenine (KYN): tryptophan (TRP)/ (KT) ratio. We sought to investigate the plasma concentration of CIT and KT ratio among the children having dehydrating diarrhea and examine associations between concentrations of CIT and KT ratio with concurrent factors. For this analysis, we used cross-sectional data from a total of 102, 6-36 months old male children who suffered from non-cholera acute watery diarrhea and had some dehydration admitted to an urban diarrheal hospital, in Bangladesh. CIT, TRP, and KYN concentrations were determined at enrollment from plasma samples using ELIZA. At enrollment, the mean plasma CIT concentration was 864.48 ± 388.55 µmol/L. The mean plasma kynurenine, tryptophan concentrations, and the KT ratio (× 1000) were 6.93 ± 3.08 µmol/L, 33.44 ± 16.39 µmol/L, and 12.12 ± 18.10, respectively. With increasing child age, KYN concentration decreased (coefficient: - 0.26; 95%CI: - 0.49, - 0.04; p = 0.021); with increasing lymphocyte count, CIT concentration decreased (coef.: - 0.01; 95% CI: - 0.02,0.001, p = 0.004); the wasted child had decreased KT ratio (coef.: - 0.6; 95% CI: - 1.18, - 0.02; p = 0.042) after adjusting for potential covariates. The CIT concentration was associated with blood neutrophils (coef.: 0.02; 95% CI: 0.01, 0.03; p < 0.001), lymphocytes (coef.: - 0.02; 95% CI: - 0.03, - 0.02; p < 0.001) and monocyte (coef.: 0.06; 95% CI: 0.01, 0.11; p = 0.021); KYN concentration was negatively associated with basophil (coef.: - 0.62; 95% CI: - 1.23, - 0.01; p = 0.048) after adjusting for age. In addition, total stool output (gm) increased (coef.: 793.84; 95% CI: 187.16, 1400.52; p = 0.011) and also increased duration of hospital stay (hour) (coef.: 22.89; 95% CI: 10.24, 35.54; p = 0.001) with increasing CIT concentration. The morphological changes associated with EED may increase the risk of enteric infection and diarrheal disease among children. Further research is critically needed to better understand the complex mechanisms by which EED biomarkers may impact susceptibility to dehydrating diarrhea in children.

RESUMO

Aflatoxin can cross the blood-brain barrier, damage brain tissues, and have the potential to harm the development of the human brain. Although dietary aflatoxin exposure is common in children, there is a paucity of data on aflatoxin exposure and child developmental outcomes. The child's cognitive, motor, and language functions were assessed using the Bayley Scales of Infant and Toddler Development-III or BSID-III at the same time points. Association between exposure to aflatoxin and subtests of BSID-III were examined using mixed-effect linear regression. Aflatoxin assays were performed on 194, 167, and 163 children at 15, 24, and 36 months of age, and chronic aflatoxin exposure was detected in 20.6%, 16.8%, and 60.7% of children, respectively. Multi-variable analyses showed that aflatoxin exposure was independently related to the children's cognitive score (ß: -0.69; 95% CI: -1.36, -0.02), receptive language score (ß: -0.90; 95% CI: -1.62, -0.17), and expressive language score (ß: -1.01; 95% CI: -1.96, -0.05). We did not observe any association between exposure to aflatoxin and the motor function of children. Chronic exposure to aflatoxin exposure was linked to reduced cognitive, expressive, and receptive language scores of the study children. Further research is needed in a different setting to confirm this novel finding.

RESUMO

Approximately one-third of children under the age of five are stunted in developing countries and many of them are micronutrient-deficient. We designed a comprehensive intervention package including egg/milk-based snacks to improve linear growth and dietary diversity among 6 to 12-month-old children in rural Bangladesh. In this 1-year community-based cluster randomized controlled longitudinal experiment, 412 mother-infant pairs were randomly assigned to receive either monthly food vouchers (for eggs, milk, semolina, sugar, and oil) to prepare egg and milk-based snacks for their children, along with multiple micronutrient powder (MNP), counseling on child feeding and handwashing, or regular government health communication alone (control; n = 206, treatment; n = 206). The trial was conducted in 12 clusters (small administrative units of sub-district). The primary inclusion criteria were ultra-poor households with limited resources and having children under 2-years-old. The primary and secondary outcomes were differences in children's length gain and dietary diversity. The effect of intervention on child growth was examined using a mixed effect linear regression model. Mean weight and length of the children did not significantly differ between groups at baseline. Around 90% of the children in both groups were breastfed. After receiving intervention for 12 months, LAZ score increased by 0.37 (CI 0.24, 0.51, p < 0.001) and risk of stunting reduced by 73% (OR: 0.27, CI 0.13, 0.58, p = 0.001). This comprehensive intervention package improved the growth and dietary diversity of children in extremely poor Bangladeshi households. A scaling-up of this intervention in contexts with limited resources should be taken into consideration.Trial registration: This trial registered retrospectively at ClinicalTrials.gov as NCT03641001, 21/8/2018.

RESUMO

(1) Background: This study aimed to investigate the existing water, sanitation, and hygiene (WASH) policy and practice of the study population and strengthen the evidence base by documenting changes in the WASH policy and practice over 3 years of the Rohingya refugee humanitarian crisis, Cox's Bazar, Bangladesh. (2) Methods: A cross-sectional surveillance design was followed; the sampling of the study population included the Rohingya refugee population and neighborhood host nationals who required hospitalization soon after seeking care and enrolled into the diarrheal disease surveillance in diarrhea-treatment centers. Throughout the study period of 3 years, a total of 4550 hospitalized individuals constituted the study participants. (3) Results: Among the hospitalized Rohingya refugee population; the use of public tap water increased significantly from 38.5% in year 1 to 91% in year 3. The use of deep tube well water significantly changed from 31.3% to 8.2%, and the use of shallow tube well water reduced significantly from 25.8% to 0.4%. Households using water seal latrine were 13.3% in year 1 and increased significantly to 31.7% in year 3. ORS consumption at home changed significantly from 61.5% in the first year to 82.1% in third year. Multivariable analysis demonstrated patients' age groups at 5 to 14 years, and 15 years and more, drinking non-tube well water, soap use after using toilet, use of non-sanitary toilet facility, father's and mother's lack of schooling, and some and severe dehydration were significantly associated with the Rohingya refugee population enrolled into the diarrheal disease surveillance. (4) Conclusion: The findings indicate significant advances in WASH service delivery as well as outreach activities by aid agencies for the Rohingya refugee population living in settlements.

RESUMO

BACKGROUND: Diarrhea is the second deadliest disease for under-five children globally and the situation is more serious in developing countries. Oral rehydration solution (ORS) is being used as a standard treatment for acute watery diarrhea for a long time. Our objective is to compare the efficacy of amino acid-based ORS "VS002A" compared to standard glucose-based WHO-ORS in infants and young children suffering from acute non-cholera watery diarrhea. METHODS: It is a randomized, double-blind, two-cell clinical trial at Dhaka Hospital of icddr,b. A total of 312 male children aged 6-36 months old with acute non-bloody watery diarrhea are included in this study. Intervention arm participants get amino acid-based ORS (VS002A) and the control arm gets standard glucose-based WHO-ORS. The primary efficacy endpoint is the duration of diarrhea in the hospital. DISCUSSION: Oral rehydration therapy (ORT) with the present ORS formulation has certain limitations - it does not reduce the volume, frequency, or duration of diarrhea. Additionally, the failure of present standard ORS to significantly reduce stool output likely contributes to the relatively limited use of ORS by mothers as they do not feel that ORS is helping their child recover from the episode of diarrhea. Certain neutral amino acids (e.g., glycine, L-alanine, L-glutamine) can enhance the absorption of sodium ions and water from the gut. By using this concept, a shelf-stable, sugar-free amino acid-based hydration medicinal food named 'VS002A' that effectively rehydrates, and improves the barrier function of the bowel following infections targeting the gastrointestinal tract has been developed. If the trial shows significant benefits of VS002A use, this may provide evidence to support consideration of the use of VS002A in the present WHO diarrhea management guidelines. Conversely, if there is no evidence of benefit, these results will reaffirm the current guidelines. TRIAL REGISTRATION: ClinicalTrials.gov NCT04677296 . Registered on December 21, 2020.

RESUMO

Background: Food safety incorporates the handling, preparation, and storage of food materials in ways that prevent foodborne illness. We aimed to investigate the typical food safety practices in a Bangladeshi slum context and to explore if stunting among school-age children was associated with various components of food safety. Method: We analysed the MAL-ED birth cohort data from the Bangladesh site. A total of 265 healthy children were enrolled in the study; we could follow up and collect food safety-related data from 187 participants. Results: The average age of the children was 6.5 years (standard deviation or SD 0.04) and 49% of them were female. About 26% of the children were stunted. In our bivariate analysis, caregivers' handwashing practice after using the toilet, treatment of drinking water, presence of insects/pests in the cooking area, and child's eating ready-made/street food more than three times per day were significantly associated with stunting. After adjusting for pertinent factors, treatment of drinking water (adjusted odds ratio or AOR = 2.50, 95% confidence interval or CI: 1.03, 6.05), and child's eating ready-made/street food more than three times/day (AOR = 2.34, 95%CI: 1.06, 5.15) remained significantly associated with stunting. Conclusions: Diverse aspects of food safety practices have a substantial association with stunting among school-age children living in an unhygienic slum environment in Dhaka, Bangladesh.

RESUMO

BACKGROUND: Bangladesh experienced a sudden, large influx of forcibly displaced persons from Myanmar in August 2017. A cholera outbreak occurred in the displaced population during September-December 2019. This study aims to describe the epidemiologic characteristics of cholera patients who were hospitalized in diarrhea treatment centers (DTCs) and sought care from settlements of Forcibly Displaced Myanmar Nationals (FDMN) as well as host country nationals during the cholera outbreak. METHODS: Diarrhea Treatment Center (DTC) based surveillance was carried out among the FDMN and host population in Teknaf and Leda DTCs hospitalized for cholera during September-December 2019. RESULTS: During the study period, 147 individuals with cholera were hospitalized. The majority, 72% of patients reported to Leda DTC. Nearly 65% sought care from FDMN settlements. About 47% of the cholera individuals were children less than 5 years old and 42% were aged 15 years and more. Half of the cholera patients were females. FDMN often reported from Camp # 26 (45%), followed by Camp # 24 (36%), and Camp # 27 (12%). Eighty-two percent of the cholera patients reported watery diarrhea. Some or severe dehydration was observed in 65% of cholera individuals. Eighty-one percent of people with cholera received pre-packaged ORS at home. About 88% of FDMN cholera patients reported consumption of public tap water. Pit latrine without water seal was often used by FDMN cholera individuals (78%). CONCLUSION: Vigilance for cholera patients by routine surveillance, preparedness, and response readiness for surges and oral cholera vaccination campaigns can alleviate the threats of cholera.

RESUMO

BACKGROUND: In August 2017, after a large influx of forcibly displaced Myanmar nationals (FDMN) in Cox's Bazar, Bangladesh diarrhea treatment centers (DTCs) were deployed. This study aims to report the clinical, epidemiological, and laboratory characteristics of the hospitalized patients. METHODS: The study followed cross-sectional design. In total 1792 individuals were studied. Other than data, a single, stool specimen was subjected to one step rapid visual diagnostic test for Vibrio cholerae. The provisionally diagnosed specimens of cholera cases were inoculated into Cary-Blair Transport Medium; then sent to the laboratory of icddr,b in Dhaka to isolate the colony as well as perform antibiotic susceptibility tests. Data were analyzed by STATA and analyses included descriptive as well as analytic methods. RESULTS: Of the total 1792 admissions in 5 DTCs, 729 (41%) were from FDMN settlements; children <5 years contributed the most (n = 981; 55%). Forty percent (n = 716) were aged 15 years and above, and females were predominant (n = 453; 63%). Twenty-eight percent (n = 502) sought treatment within 24h of the onset of diarrhea. FDMN admissions within 24h were low compared to host hospitalization (n = 172, 24% vs. n = 330, 31%; p<0.001). Seventy-two percent (n = 1295) had watery diarrhea; more common among host population than FDMN (n = 802; 75% vs. n = 493; 68%; p<0.001). Forty-four percent admissions (n = 796) had some or severe dehydration, the later was common in FDMN (n = 46; 6% vs. n = 36; 3%, p = 0.005). FDMN often used public taps (n = 263; 36%), deep tube-well (n = 243; 33%), and shallow tube well (n = 188; 26%) as the source of drinking water. Nearly 96% (n = 698) of the admitted FDMN used pit latrines as opposed to 79% (n = 842) from the host community (p<0.001). FDMN children were often malnourished. None of the FDMN reported cholera. CONCLUSION: No diarrhea outbreak was detected, but preparedness for surges and response readiness are warranted in this emergency and crisis setting.

RESUMO

BACKGROUND/OBJECTIVES: Stunted children often have poor appetite, which may limit their response to nutritional interventions. We investigated the effect of a nutritional intervention on the appetite status of stunted children. METHODS: A longitudinal prospective intervention study was conducted with 50 stunted (length for age; LAZ < -2) (age and sex matched) aged 12-18 months and their mothers in Bauniabadh slum of Dhaka city. The stunted children received the following intervention package: one boiled egg and 150 ml milk daily 6 days a week for 3 months; psychosocial stimulation including structured play activities and parental counseling for 6 months; routine clinical care. Appetite status was measured using an interview-based tool "Early Childhood Appetite and Satiety Tool." RESULTS: Over the period of nutritional intervention, the mean appetite score increased from 49 to 60 in the stunted children and was associated with increased food consumption. Over the intervention period, both egg and milk consumption increased (40.3-49.6 g and 83.8-138.5 ml, respectively). CONCLUSIONS: Assessment of appetite status using EACST appears to be a useful tool for monitoring a nutritional intervention in stunted children. This tool may be useful for programs in managing child stunting in low-income countries and an important way to assess the efficacy of a nutritional intervention in these children.

RESUMO

BACKGROUND: Multiple factors constrain the trajectories of child cognitive development, but the drivers that differentiate the trajectories are unknown. We examine how multiple early life experiences differentiate patterns of cognitive development over the first 5 years of life in low-and middle-income settings. METHODS: Cognitive development of 835 children from the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) multisite observational cohort study was assessed at 6, 15, 24 (Bayley Scales of Infant and Toddler Development), and 60 months (Wechsler Preschool and Primary Scale of Intelligence). Markers of socioeconomic status, infection, illness, dietary intake and status, anthropometry, and maternal factors were also assessed. Trajectories of development were determined by latent class-mixed models, and factors associated with class membership were examined by discriminant analysis. RESULTS: Five trajectory groups of cognitive development are described. The variables that best discriminated between trajectories included presence of stimulating and learning resources in the home, emotional or verbal responsivity of caregiver and the safety of the home environment (especially at 24 and 60 months), proportion of days (0-24 months) for which the child had diarrhea, acute lower respiratory infection, fever or vomiting, maternal reasoning ability, mean nutrient densities of zinc and phytate, and total energy from complementary foods (9-24 months). CONCLUSIONS: A supporting and nurturing environment was the variable most strongly differentiating the most and least preferable trajectories of cognitive development. In addition, a higher quality diet promoted cognitive development while prolonged illness was indicative of less favorable patterns of development.

RESUMO

BACKGROUND: Globally more than 150 million children under age 5 years were stunted in 2018, primarily in low- and middle-income countries (LMICs), and the impact of early-onset, persistent stunting has not been well explored. To explore the association between early-onset persistent stunting in children and cognitive development at 5 years of age, and to identify the factors associated with early-onset stunting. METHODS AND FINDINGS: Children from the MAL-ED cohort study were followed from birth to 5 years of age in six LMICs. The Wechsler Preschool Primary Scales of Intelligence (WPPSI) was used to assess cognitive abilities (fluid reasoning) at 5 years and was adapted for each culture. Stunting was categorized as early-onset persistent (first stunted at 1-6 months and persisting at 60 months), early-onset recovered (first stunted at 1-6 months and not stunted at 60 months), late-onset persistent (first stunted at 7-24 months and persisting at 60 months), late-onset recovered (first stunted at 7-24 months and not stunted at 60 months), and never (never stunted). Mixed effects linear models were used to estimate the relationship between stunting status and cognitive development. Children with early-onset persistent stunting had significantly lower cognitive scores (-2.10 (95% CI: -3.85, -0.35)) compared with those who were never stunted. Transferrin receptor (TfR) was also negatively associated with cognitive development (-0.31 (95% CI: -0.49, -0.13)), while the HOME inventory, an index of quality of the home environment (0.46 (95% CI: 0.21, 0.72)) and socio-economic status (1.50 (95% CI: 1.03, 1.98)) were positively associated with cognitive development. CONCLUSIONS: Early-onset persistent stunting was associated with lower cognitive development in children at 5 years of age in this cohort of children.

RESUMO

Information on the association between stunting and child development is limited from low-income settings including Bangladesh where 36% of children under- 5 are stunted. This study aimed to explore differences in early childhood development (ECD) between stunted (length-for-age z-score [LAZ] < -2) and nonstunted (LAZ ≥ -2) children in Bangladesh. Children (n = 265) aged 6-24 months who participated in the MAL-ED birth cohort study were evaluated by trained psychologists at 6, 15, and 24 months of age using the Bayley Scales of Infant and Toddler Development-III; child length and weight were measured using standard procedures. ECD scores (z-scores derived from cognitive, motor, language and socio-emotional skills) were compared between stunted, underweight (weight-for-age z-score < -2), and wasted (weight-for-length z-score < -2) children, controlling for child age and sex and maternal age, education, body mass index (BMI), and depressive symptoms. Stunted children had significantly lower ECD scores than their nonstunted peers on cognitive (P = .049), motor (P < .001), language (P < .001) and social-emotional (P = .038) scales where boys had significantly lower fine motor skills compared with girls (P = .027). Mother's schooling and BMI were significant predictors of ECD. Similar to stunting, underweight children had developmental deficits in all domains (cognitive: P = .001; fine motor: P = .039, and P < .001 for both gross motor and total motor; expressive communication: P = .032; total language: P = .013; social-emotional development: P = .017). Wasted children had poor motor skills (P = .006 for the fine motor; P < .001 for both gross motor and total motor development) compared with the nonwasted peers. Early childhood stunting and underweight were associated with poor developmental outcomes in Bangladesh.

RESUMO

Growth in young children is controlled through the release of several hormonal signals, which are affected by diet, infection, and other exposures. Stunting is clearly a growth disorder, yet limited evidence exists documenting the association of different growth biomarkers with child stunting. This study explored the association between different growth biomarkers and stunting in Bangladeshi children. A quasi-experimental study was conducted among 50 stunted (length-for-age Z-score (LAZ) < -2 SD) and 50 control (LAZ ≥ -2 SD) children, aged 12-18 months, residing in a Bangladeshi slum. The enrolled stunted children received an intervention package, which included food supplementation for three months, psychosocial stimulation for six months, and routine clinical care on community nutrition center at the study field site. The controls received routine clinical care only. All children were clinically screened over the study period. Length, weight, fasting blood and fecal biomarkers were measured. All biomarkers levels were similar in both groups except for oxyntomodulin at enrolment. Leptin (adjusted odds ratio, AOR: 4.0, p < 0.01), leptin-adiponectin ratio (AOR 5.07 × 108, p < 0.01), insulin-like growth factor-1 (IGF-1) (AOR 1.02, p < 0.05), and gamma interferon (IFN-γ) (AOR 0.92, p < 0.05) levels were independently associated with stunting at enrolment. Serum leptin, leptin-adiponectin ratio, interleukin-6 (IL-6), IL-10, tumor necrosis factor-alpha (TNF-α), and fecal alpha-1-antitrypsin (AAT) levels increased significantly (p < 0.001), while IFN-γ levels significantly decreased among stunted children after six months of intervention. Leptin, leptin-adiponectin ratio, IGF-1, and IFN-γ are independently associated with stunting in Bangladeshi children. This trial was registered at clinicaltrials.gov as NCT02839148.

RESUMO

BACKGROUND: Undernutrition and poor cognitive development affect many children in developing countries. Good nutrition and health care are essential for optimal child development and growth. OBJECTIVES: We assessed the impact of peer counseling combined with psychosocial stimulation on feeding practices and child growth and development in slums in Bangladesh. METHODS: We performed a community-based cluster randomized controlled trial in selected slums; 350 mother-infant pairs were allocated to receive peer counseling on feeding practices plus psychosocial stimulation (PC + PCS; n = 175) or usual health messages (control; n = 175) using restricted randomization. Data were collected at enrollment and 1, 3, 5, 7, 9, and 12 mo after delivery. We collected data on infant and young child feeding practices and anthropometric measurements from birth until 12 mo to assess the main outcomes, including feeding practices and growth. We used the Bayley Scale III at 12 mo to assess child development. The effects of the PC + PCS intervention were assessed by using regression models. RESULTS: More mothers in the PC + PCS group than in the control group reported early initiation of breastfeeding (in the first hour: 89% compared with 78%, respectively; P < 0.05) and exclusive breastfeeding at 5 mo (73% compared with 27%, respectively; P < 0.001). Peer counseling had positively impacted infant length gain at 12 mo (P < 0.005). Children in the PC + PCS group were found to be more socially and emotionally active compared with controls at 12 mo (standardized score: 0.165 compared with -0.219, respectively; P < 0.05). CONCLUSION: Combining peer counseling with psychosocial stimulation had positive effects on infant feeding practices and growth at 12 mo and on the social-emotional development of young children. This trial was registered at clinicaltrial.gov as NCT03040375.

RESUMO

BACKGROUND: Child cognitive development is influenced by early-life insults and protective factors. To what extent these factors have a long-term legacy on child development and hence fulfillment of cognitive potential is unknown. OBJECTIVE: The aim of this study was to examine the relation between early-life factors (birth to 2 y) and cognitive development at 5 y. METHODS: Observational follow-up visits were made of children at 5 y, previously enrolled in the community-based MAL-ED longitudinal cohort. The burden of enteropathogens, prevalence of illness, complementary diet intake, micronutrient status, and household and maternal factors from birth to 2 y were extensively measured and their relation with the Wechsler Preschool Primary Scales of Intelligence at 5 y was examined through use of linear regression. RESULTS: Cognitive T-scores from 813 of 1198 (68%) children were examined and 5 variables had significant associations in multivariable models: mean child plasma transferrin receptor concentration (ß: -1.81, 95% CI: -2.75, -0.86), number of years of maternal education (ß: 0.27, 95% CI: 0.08, 0.45), maternal cognitive reasoning score (ß: 0.09, 95% CI: 0.03, 0.15), household assets score (ß: 0.64, 95% CI: 0.24, 1.04), and HOME child cleanliness factor (ß: 0.60, 95% CI: 0.05, 1.15). In multivariable models, the mean rate of enteropathogen detections, burden of illness, and complementary food intakes between birth and 2 y were not significantly related to 5-y cognition. CONCLUSIONS: A nurturing home context in terms of a healthy/clean environment and household wealth, provision of adequate micronutrients, maternal education, and cognitive reasoning have a strong and persistent influence on child cognitive development. Efforts addressing aspects of poverty around micronutrient status, nurturing caregiving, and enabling home environments are likely to have lasting positive impacts on child cognitive development.

RESUMO

Mandatory fortification of edible oil (soybean and palm) with vitamin A was decreed in Bangladesh in 2013. Yet, there is a dearth of data on the availability and consumption of vitamin A fortifiable oil at household level across population sub-groups. To fill this gap, our study used a nationally representative survey in Bangladesh to assess the purchase of fortifiable edible oil among households and project potential vitamin A intake across population sub-groups. Data is presented by strata, age range and poverty-the factors that potentially influence oil coverage. Across 1,512 households, purchase of commercially produced fortifiable edible oil was high (87.5%). Urban households were more likely to purchase fortifiable oil (94.0%) than households in rural low performing (79.7%) and rural other strata (88.1%) (p value: 0.01). Households in poverty were less likely to purchase fortifiable oil (82.1%) than households not in poverty (91.4%) (p <0.001). Projected estimates suggested that vitamin A fortified edible oil would at least partially meet daily vitamin A estimated average requirement (EAR) for the majority of the population. However, certain population sub-groups may still have vitamin A intake below the EAR and alternative strategies may be applied to address the vitamin A needs of these vulnerable sub-groups. This study concludes that a high percentage of Bangladeshi population across different sub-groups have access to fortifiable edible oil and further provides evidence to support mandatory edible oil fortification with vitamin A in Bangladesh.

RESUMO

Reliable and validated tools for measuring appetite of children in South Asia are not available. This study aimed to develop and validate a tool for assessing appetite level of under-five children. Based on literature review and findings from focus group discussions (FGDs), an initial 27-item interview-based tool, the "Early Childhood Appetite and Satiety Tool (ECAST)" was developed in Bangladesh. Fourteen FGDs were carried out in rural and urban settings and constructs for inclusion were derived from the themes and coding of FGDs and appetite assessment tools used in Western contexts. For structural validation, the ECAST-27-was administered on 150 mothers/primary caregivers of children aged 6-59 months, living in urban and rural areas. To validate the association with other variables, the ECAST was administered on mothers of children aged 12-24 months in the community (N = 50), and two groups of wasted, hospitalized children (Weight-for-length, Z score <-2SD) [group1: twenty acutely ill children aged 6-59 months; group 2: twenty children in nutritional rehabilitation aged 18-24 months]. Reliability of ECAST was estimated using Cronbach's alpha and Pearson's correlation coefficient. Kaiser-Meyer-Olkin = 0.73 and the Bartlett's test of sphericity, χ2(253) = 755.791, p < 0.001 indicated that the raw data were suitable. Given the convergence of the Scree plot, Kaiser's criterion and dropping of cross loading items, a 16-item ECAST was produced with three sub scales: Appetite cue; Food responsiveness and Emotion and preference, which were internally valid and had good test-retest reliability (Cronbach's alpha 0.6 and test-retest reliability 0.797). Total ECAST scores of wasted children with good appetite were significantly higher from those with poor appetite (p = 0.004 and 0.001 for two wasted groups respectively). Results suggest that ECAST may provide a useful measure to assess the appetite level of under-five children.

RESUMO

Child undernutrition has multifactorial causes, ranging from food insecurity to etiologies refractory to conventional nutritional approaches, such as infections, environmental enteric dysfunction, and other conditions that lead to systemic inflammation. Poor appetite may be an important symptom of these causes and may be a useful marker of an undernourished child's ability to recover. We conducted a systematic review to characterize the methods and tools to measure appetite among children <5 y old in low- and middle-income countries. A systematic search of 8 databases identified 23 eligible studies published since 1995. Thirteen described methods based on direct feeding observation or quantification of nutrient intake from caregiver report, 16 described tools that assessed caregiver perceptions of appetite, and 6 reported assessments in both categories. Four studies that gauged caregiver perceptions assessed multiple appetite domains, whereas 12 assessed 1 domain-often with a single question. Only 6 studies reported validation processes, the most common of which compared an observed test meal with daily energy intake. No studies reported the use of a method or tool that was validated in multiple cultural or linguistic contexts. Although dietary intake measures and observed feeding tests have shown validity in some contexts, they are resource intensive. Subjective caregiver questionnaires may offer a more efficient appetite evaluation method, but they have been evaluated less consistently. A rigorously developed and validated tool to rapidly assess child appetite is needed and could be best addressed by a questionnaire that leverages the multiple domains of appetite. The application of interventions that target causes of undernutrition that are not amenable to food-based interventions in clinical or research contexts could be facilitated by an efficient appetite screening tool to identify appetite-related causes of undernutrition and to monitor children's response to such interventions.
