Burden of undernutrition among under-five Bengali children and its determinants: Findings from Demographic and Health Surveys of Bangladesh and India.

BACKGROUND: Globally, undernutrition is the leading cause of mortality among under-five children. Bangladesh and India were in the top ten countries in the world for under-five mortality. The aim of the study was to investigate the nutritional status of Bengali under-five children. METHODS: Data on 25938 under-five children were retrieved from the Bangladesh Demographic and Health Survey 2017-18 (BDHS) and the National Family Health Survey of India 2015-16 (NFHS-4). Stunting, wasting, underweight and thinness were considered to understand the nutritional status of under-five children. Binary logistic regression was used to identify associated factors of undernutrition among children. RESULTS: Over one-quarter of Bengali under-five children were found to be suffering from the problem of stunting (31.9%) and underweight (28.1%), while other nutritional indicators raised serious concern and revealed inter-country disparities. In the cases of wasting, underweight and thinness, the mean z-scores and frequency differences between Bangladesh and India were significant. The nutritional status of Bengali under-five children appeared to have improved in Bangladesh compared to India. Child undernutrition had significant relations with maternal undernutrition in both countries. Girls in Bangladesh had slightly better nutritional status than boys. In Bangladesh, lack of formal education among mothers was a leading cause of child undernutrition. Stunting and underweight coexist with low household wealth index in both counties. CONCLUSIONS: The research revealed that various factors were associated with child undernutrition in Bengalis. It has been proposed that programmes promoting maternal education and nutrition, along with household wealth index be prioritised. The study recommends that the Governments of Bangladesh and India should increase the budget for health of children so as to reach the sustainable development goals.

Impact of Rotaviral Diarrhea on Child Growth in Sub-Saharan Africa and South Asia in the Global Enteric Multicenter Study.

Rotavirus is the leading cause of dehydrating diarrhea among children in developing countries. The impact of rotaviral diarrhea on nutritional status is not well understood. We aimed to determine the association between rotavirus-positive moderate-to-severe diarrhea and nutrition in children under 5 years of age. We analyzed data from the Global Enteric Multicenter Study on children 0-59 months old from South Asia and sub-Saharan Africa. The relationships between explanatory variables and outcome variables were assessed using multiple linear regression; the explanatory variable was the presence of rotavirus in the stool sample, and the outcome variables were z scores [length/height-for-age (LAZ/HAZ), weight-for-age (WAZ), and weight-for-length/height (WLZ/WHZ)] at follow-up (∼60 days). The prevalence of rotaviral diarrhea was 17.3% (905/5,219) in South Asia and 19.95% (842/4,220) in sub-Saharan Africa. Rotavirus was associated with higher LAZ/HAZ (ß: 0.19; 95% CI: 0.12, 0.26; P <0.001) and WAZ (ß: 0.15; 95% CI: 0.79, 0.22; P <0.001) in sub-Saharan Africa and with lower WLZ/WHZ (ß coefficient: -0.08; 95% CI: -0.15, -0.009; P = 0.027) in South Asia. Our study indicates that rotaviral diarrhea is positively associated with nutritional status in sub-Saharan Africa and is negatively associated with nutritional status in South Asia. An expedited implementation policy of ongoing preventive and control strategies, including vaccination against rotavirus, is necessary to reduce the burden of rotaviral diarrhea, which may further help to reduce the potential nutritional ramifications.

Performance of chest X-ray scoring in predicting disease severity and outcomes of patients hospitalised with COVID-19 in Bangladesh.

Introduction: Evaluation of potential outcomes of COVID-19-affected pneumonia patients using computed tomography scans may not be conceivable in low-resource settings. Thus, we aimed to evaluate the performance of chest X-ray scoring in predicting the disease severity and outcomes of adults hospitalised with COVID-19. Methods: This was a retrospective chart analysis consuming data from COVID-19-positive adults who had chest X-ray availability and were admitted to a temporary COVID unit, in Bangladesh from 23rd April 2020 to 15th November 2021. At least one clinical intensivist and one radiologist combinedly reviewed each admission chest X-ray for the different lung findings. Chest X-ray scoring varied from 0 to 8, depending on the area of lung involvement with 0 indicating no involvement and 8 indicating ⩾75% involvement of both lungs. The receiver operating characteristic curve was used to determine the optimum chest X-ray cut-off score for predicting the fatal outcomes. Result: A total of 218 (82.9%) out of 263 COVID-19-affected adults were included in the study. The receiver operating characteristic curve demonstrated the optimum cut-off as ⩾3 and ⩾5 for disease severity and death, respectively. In multivariate logistic regression analysis, a chest X-ray score of ⩾3 was found to be independently associated with disease severity (aOR: 8.70; 95% CI: 3.82, 19.58, p < 0.001) and a score of ⩾5 with death (aOR: 16.53; 95% CI: 4.74, 57.60, p < 0.001) after adjusting age, sex, antibiotic usage before admission, history of fever, cough, diabetes mellitus, hypertension, total leukocytes count and C-reactive protein. Conclusion: Using chest X-ray scoring derived cut-off at admission might help to identify the COVID-19-affected adults who are at risk of severe disease and mortality. This may help to initiate early and aggressive management of such patients, thereby reducing their fatal outcomes.

Comparison of Characteristics of Children with Severe Acute and Chronic Malnutrition Hospitalized with Diarrhea.

Children with malnutrition present with aberrant laboratory parameters. This study aimed to identify high-risk diarrheal children with varied nutritional status. The data were obtained from the electronic database of Dhaka Hospital, International Centre for Diarrhoeal Disease Research, Bangladesh from 2019 to 2021. Among 1,068 children under 5 years of age with diarrhea, 177 (14%) had severe acute malnutrition (SAM; weight-for-length/height Z score < -3), 239 children (17%) had severe stunting (SS; length/height-for-age Z score < -3), and 652 did not have malnutrition (weight-for-length/height and weight-for-age and length/height-for-age Z score > -2). We independently assessed the relationship of nutritional profiles with each clinical and laboratory parameter. After adjustment for age and sex in the multiple regression model, hyponatremia (adjusted odds ratio [aOR] = 2.37 [95% CI: 1.52-3.68]; P < 0.001) and dehydration (aOR = 2.42 [95% CI: 1.67-3.52]; P < 0.001) were independently associated with SAM compared with children without malnutrition. In comparison to non-malnutrition, SS was less likely to be associated with acute watery diarrhea (aOR = 0.66 [95% CI: 0.47-0.92]; P = 0.014) but was significantly associated with anemia (aOR = 2.18 [95% CI: 1.57-3.02]; P < 0.001) and thrombocytosis (aOR = 2.43 [95% CI: 1.78-3.32]; P < 0.001). The presence of hypernatremia was substantially lower in children with SAM (aOR = 0.38 [95% CI: 0.22-0.65]; P < 0.001) or SS (aOR = 0.56 [95% CI: 0.35-0.88]; P = 0.012) than in children without malnutrition. Severe stunting was less likely to be associated with dehydration (aOR = 0.44 [95% CI: 0.29-0.67]; P < 0.001) in contrast to SAM. Therefore, children hospitalized with diarrhea may have different clinical and laboratory manifestations depending on their nutritional status and may require differential treatment.

Symptomatic and asymptomatic enteric protozoan parasitic infection and their association with subsequent growth parameters in under five children in South Asia and sub-Saharan Africa.

BACKGROUND: Entamoeba histolytica, Giardia, and Cryptosporidium are common intestinal protozoan parasites that contribute to a high burden of childhood morbidity and mortality. Our study quantified the association between intestinal protozoan parasites and child anthropometric outcomes among children under-5. METHODS: We analyzed data from 7,800 children enrolled in the Global Enteric Multicenter Study (GEMS) across seven study sites that were positive for intestinal protozoan parasites between December 2007 and March 2011. Parasites were assessed using stool immunoassays (ELISA). We applied multiple linear regression to test the association between any or concurrent parasite and child anthropometric outcomes: length/height-for-age (HAZ), weight-for-age (WAZ), and weight-for-length/height (WHZ) z-score after 60 days of enrollment. Models were stratified by diarrheal symptoms, driven by the study design, and adjusted for potential covariates. FINDINGS: During the follow-up at day 60 after enrollment, child anthropometric outcomes, among the asymptomatic children showed, negative associations between Giardia with HAZ [ß: -0.13; 95% CI: -0.17, -0.09; p<0.001] and WAZ [ß -0.07; 95% CI: -0.11, -0.04; p<0.001], but not WHZ [ß: -0.02; 95% CI:-0.06, 0.02; p = 0.36]; Cryptosporidium with WAZ [ß: -0.15; 95% CI: -0.22, -0.09; p<0.001] and WHZ [ß: -0.18; 95%CI: -0.25, -0.12; p<0.001], but not with HAZ [ß: -0.03; 95% CI: -0.09, 0.04; p = 0.40]. For symptomatic children, no associations were found between Giardia and anthropometry; negative associations were found between Cryptosporidium with HAZ [ß: -0.17; 95% CI: -0.23, -0.11; p<0.001], WAZ [ß: -0.25; 95% CI: -0.31, -0.19; p<0.001] and WHZ [ß: -0.23; 95% CI: -0.30, -0.17; p<0.001]. Among the asymptomatic 24-59 months children, Giardia had a negative association with HAZ [ß: -0.09; 95% CI: -0.15, -0.04; p = 0.001]. No significant associations were found between E. histolytica with child growth. CONCLUSIONS: While some studies have found that Giardia is not associated with (or protective against) acute diarrhea, our findings suggest that it is associated with growth shortfall. This observation underscores the need for preventive strategies targeting enteric protozoan parasites among young children, to reduce the burden of childhood malnutrition.

Assessing the Impact of a Handwashing Knowledge and Practices Program among Poor Households in Rural Bangladesh: A Cluster-Randomized Pre-Post Study.

Improvement in hand hygiene has been strongly associated with positive outcomes in maternal and child health. Although Bangladesh has a high level of awareness of key hygiene messages, the practice of handwashing, the most effective hygiene behavior, is low. Suchana, a multisectoral nutrition program, aims to increase knowledge and practices around various water, sanitation, and hygiene settings in Sylhet region, the northeast of rural Bangladesh. This study aimed to investigate the changes in indicators related to handwashing knowledge and practices among Suchana beneficiaries in final compared with baseline evaluations. Data were derived from the baseline and final cross-sectional evaluation survey. The following handwashing knowledge and practices were considered: handwashing before preparing food, before eating food and feeding children, before serving food, after defecation, and after touching animals. The descriptive findings indicate that Suchana intervention improved handwashing knowledge and practices in the intervention area compared with the control. The odds of having knowledge of hand washing before preparing food (adjusted odds ratio [aOR]: 1.60; 95% CI: 1.30-1.98), before eating food and feeding children (aOR: 1.68; 95% CI: 1.25-2.25), before serving food (aOR: 1.35; 95% CI: 1.04-1.76), after defecation (aOR: 1.74; 95% CI: 1.25-2.41), and after touching animals (aOR: 1.67; 95% CI: 1.29-2.16) were higher in intervention area than the control area. Similarly, the impact on maternal handwashing practices at final evaluation indicated successful effects of the intervention. These results suggest scaling-up of similar interventions for larger populations living in vulnerable areas of rural Bangladesh.

A predictive modelling approach to illustrate factors correlating with stunting among children aged 12-23 months: a cluster randomised pre-post study.

OBJECTIVE: The aim of this study was to construct a predictive model in order to develop an intervention study to reduce the prevalence of stunting among children aged 12-23 months. DESIGN: The study followed a cluster randomised pre-post design and measured the impacts on various indicators of livelihood, health and nutrition. The study was based on a large dataset collected from two cross-sectional studies (baseline and endline). SETTING: The study was conducted in the north-eastern region of Bangladesh under the Sylhet division, which is vulnerable to both natural disasters and poverty. The study specifically targeted children between the ages of 12 and 23 months. MAIN OUTCOME MEASURES: Childhood stunting, defined as a length-for-age z-score <-2, was the outcome variable in this study. Logistic and probit regression models and a decision tree were constructed to predict the factors associated with childhood stunting. The predictive performance of the models was evaluated by computing the area under the receiver operating characteristic (ROC) curve analysis. RESULTS: The baseline survey showed a prevalence of 52.7% stunting, while 50.0% were stunted at endline. Several factors were found to be associated with childhood stunting. The model's sensitivity was 61% and specificity was 56%, with a correctly classified rate of 59% and an area under the ROC curve of 0.615. CONCLUSION: The study found that childhood stunting in the study area was correlated with several factors, including maternal nutrition and education, food insecurity and hygiene practices. Despite efforts to address these factors, they remain largely unchanged. The study suggests that a more effective approach may be developed in future to target adolescent mothers, as maternal nutrition and education are age-dependent variables. Policy makers and programme planners need to consider incorporating both nutrition-sensitive and nutrition-specific activities and enhancing collaboration in their efforts to improve the health of vulnerable rural populations.

Influence of the Suchana intervention on exclusive breastfeeding and stunting among children aged under 6 months in the Sylhet region of Bangladesh.

Exclusive breastfeeding (EBF) provides significant health benefits to children. However, mothers may find it difficult to continue EBF for 6 months. The present analysis aimed to examine the influence of the Suchana intervention-a large-scale programme implemented with the aim of improving the health and nutritional status of mothers and children from poor households in the Sylhet region of Bangladesh-on EBF and stunting among children under 6 months. Baseline and endline data were obtained from the Suchana evaluation. EBF was defined as an infant (<6 months) only receiving breast milk in the previous 24 h. Childhood stunting was defined as a length-for-age z-score of less than -2 among children of the same age. Multiple logistic regression analysis was used to assess the associations of the Suchana intervention with EBF and stunting. EBF prevalence improved from 64% at baseline to 85% at the endline in the intervention area, with the intervention group having 2.25 times higher odds of EBF compared to the control group. Stunting prevalence reduced from 28% at baseline to 24% at the endline in the intervention group, but after controlling for covariates, the association between stunting and the intervention was not significant. However, the interaction analysis showed significantly lower stunting prevalence among EBF children in both intervention and control areas. The Suchana intervention had a positive impact on the EBF practice of rural children in a vulnerable region of Bangladesh, and EBF was identified as a significant factor associated with stunting. The findings suggest that the continuation of the EBF intervention has the potential to have an impact on reducing stunting in the region, highlighting the importance of promoting EBF to improve child health and development.

Site-Specific Incidence Rate of Blastocystis hominis and Its Association with Childhood Malnutrition: Findings from a Multi-Country Birth Cohort Study.

In this study, we investigated the potential association between the burden of asymptomatic Blastocystis spp. (Blastocystis hominis) infection and nutritional status among children under 2 years of age using the data collected from 1,715 children from eight distinct geographic locations, including Bangladesh, Brazil, India, Peru, Tanzania, Pakistan, Nepal, and South Africa. Childhood stunting, wasting, and underweight were the outcome variables, and B. hominis infection was the exposure variable of this present study. The presence of B. hominis in nondiarrheal stools was evaluated by TaqMan Array Cards. Site-specific incidence rates were estimated using Poisson regression, and multiple generalized estimating equation was used to assess the association between the B. hominis infection and nutritional status. The site-specific incidence rates of asymptomatic B. hominis infections per 100 child-months were higher in Tanzania, Peru, and South Africa when compared with the other study sites. Moreover, in terms of site-specific association, childhood stunting was significantly associated with asymptomatic B. hominis infection in Bangladesh (odds ratio [OR]: 1.62; 95% CI: 1.26-2.08), India (OR: 1.78; 95% CI: 1.46-2.16), Nepal (OR: 2.26; 95% CI: 1.60-3.21), Peru (OR: 1.47; 95% CI: 1.26-1.71), South Africa (OR: 1.57; 95% CI: 1.35-1.83), and Tanzania (OR: 2.46; 95% CI: 2.18-2.79) sites. Wasting was associated with B. hominis in the Brazil site only (OR: 3.19; 95% CI: 1.31-7.77). On the other hand, underweight was associated in the Bangladesh (OR: 1.89; 95% CI: 1.48-2.42), Brazil (OR: 4.41; 95% CI: 1.57-12.4), Nepal (OR: 2.25; 95% CI: 1.52-3.35), and Tanzania (OR: 1.68; 95% CI: 1.42-1.99) sites. Our analysis further reveals that the presence of additional pathogens may play a pathogenic role in children who have B. hominis infection.

Site-Specific Analysis of the Incidence Rate of Enterotoxigenic Escherichia coli Infection Elucidates an Association with Childhood Stunting, Wasting, and Being Underweight: A Secondary Analysis of the MAL-ED Birth Cohort.

Asymptomatic infection by fecal enteropathogens is a major contributor to childhood malnutrition. Here, we investigated the incidence rate of asymptomatic infection by enterotoxigenic Escherichia coli (ETEC) and assessed its association with childhood stunting, wasting, and being underweight among children under 2 years of age. The Malnutrition and Enteric Disease birth cohort study included 1,715 children who were followed from birth to 24 months of age from eight distinct geographic locations including Bangladesh, Brazil, India, Peru, Tanzania, Pakistan, Nepal, and South Africa. The TaqMan array card assay was used to determine the presence of ETEC in the nondiarrheal stool samples collected from these children. Poisson regression was used to estimate the incidence rate, and multiple generalized estimating equations with binomial family, logit link function, and exchangeable correlation were used to analyze the association between asymptomatic ETEC infection and anthropometric indicators such as stunting, wasting, and being underweight. The site-specific incidence rates of asymptomatic ETEC infections per 100 child-months were also higher at the study locations in Tanzania (54.81 [95% CI: 52.64, 57.07]) and Bangladesh (46.75 [95% CI: 44.75, 48.83]). In the Bangladesh, India, and Tanzania sites, the composite indicator of anthropometric failure was significantly associated with asymptomatic ETEC infection. Furthermore, a significant association between asymptomatic heat-stable toxin ETEC infections and childhood stunting, wasting, and being underweight was found in only the Bangladesh and Tanzania sites.

Vibrio cholerae in rural and urban Bangladesh, findings from hospital-based surveillance, 2000-2021.

With more than 100,000 cases estimated each year, Bangladesh is one of the countries with the highest number of people at risk for cholera. Moreover, Bangladesh is formulating a countrywide cholera-control plan to satisfy the GTFCC (The Global Task Force on Cholera Control) Roadmap's goals. With a particular focus on cholera trends, variance in baseline and clinical characteristics of cholera cases, and trends in antibiotic susceptibility among clinical isolates of Vibrio cholerae, we used data from facility-based surveillance systems from icddr,b's Dhaka, and Matlab Hospitals from years 2000 to 2021. Female patients comprised 3,553 (43%) in urban and 1,099 (51.6%) in rural sites. Of the cases and most patients 5,236 (63.7%) in urban and 1,208 (56.7%) in the rural site were aged 15 years and more. More than 50% of the families belonged to the poor and lower-middle-class; in 2009 (24.4%) were in urban and in 1,791 (84.2%) were in rural sites. In the urban site, 2,446 (30%) of households used untreated drinking water, and 702 (9%) of families disposed of waste in their courtyard. In the multiple logistic regression analysis, the risk of cholera has significantly increased due to waste disposal in the courtyard and the boiling of water has a protective effect against cholera. Rotavirus (9.7%) was the most prevalent co-pathogen among the under-5 children in both sites. In urban sites, the percentage of V. cholerae along with co-existing ETEC and Campylobacter is changing in the last 20 years; Campylobacter (8.36%) and Enterotoxigenic Escherichia coli (ETEC) (7.15%) were the second and third most prevalent co-pathogens. Shigella (1.64%) was the second most common co-pathogen in the rural site. Azithromycin susceptibility increased slowly from 265 (8%) in 2006-2010 to 1485 (47.8%) in 2016-2021, and erythromycin susceptibility dropped substantially over 20 years period from 2,155 (98.4%) to 21 (0.9%). Tetracycline susceptibility decreased in the urban site from 2051 (45.9%) to 186 (4.2%) and ciprofloxacin susceptibility decreased from 2,581 (31.6%) to 1,360 (16.6%) until 2015, then increased 1,009 (22.6%) and 1,490 (18.2%) in 2016-2021, respectively. Since 2016, doxycycline showed 902 (100%) susceptibility. Clinicians need access to up-to-date information on antimicrobial susceptibility for treating hospitalized patients. To achieve the WHO-backed objective of eliminating cholera by 2030, the health systems need to be put under a proper surveillance system that may help to improve water and sanitation practices and deploy oral cholera vaccines strategically.

What Makes Bangladeshi Pregnant Women More Compliant to Iron-Folic Acid Supplementation: A Nationally Representative Cross-Sectional Survey Result.

BACKGROUND: Iron-Folic Acid Supplementation (IFAS) is an effective strategy to prevent iron deficiency anemia during pregnancy. We aimed to explore the key factors associated with compliance to IFA tablets in Bangladesh. METHODS: This study analyzed the 2017-2018 Bangladesh Demographic and Health Survey data of 3828 pregnant women aged 15-49 years. We categorized compliance into two categories; at least 90 days and full 180 days of consumption. We performed multivariable logistic regression to identify the association between key factors and IFAS compliance. RESULTS: The prevalence of consumption of IFA tablets for at least 90 days was 60.64%, and only 21.72% of women consumed the IFA for the full 180 days. About three-quarters of the women (73.36%) having at least four antenatal care visits (ANC) consumed IFA for at least 90 days, whereas only three in ten women (30.37%) consumed IFA for a minimum of 180 days. For compliance with IFA for at least 90 days, respondent's age of 20-34 years (aOR 1.26, 95% CI 1.03-1.54), respondent's educational qualification of secondary (aOR 1.77, 95% CI 1.16-2.70) or higher (aOR 2.73, 95% CI 1.65-4.53), husband's educational qualification of secondary (aOR 1.33, 95% CI 1.00-1.77) or higher (aOR 1.75, 95% CI 1.22-2.52), and having received at least four antenatal care (ANC) visits from medically skilled providers (aOR 2.53, 95% CI 2.14-3.00) were significantly associated with higher odds of compliance. For compliance with IFA for at least 180 days, respondent's educational qualification of higher (aOR 2.45, 95% CI 1.34-4.48), and having received at least four ANC visits from medically skilled providers (aOR 2.43, 95% CI 1.97-3.00) were significantly associated with higher odds of compliance. Intimate partner violence was negatively associated with compliance with IFA for at least 180 days (aOR 0.62, 95% CI 0.48-0.81). CONCLUSIONS: The full compliance to IFAS is still sub-optimal in Bangladesh. Further precise context-specific intervention strategies must be developed and implemented with fidelity.

Citrulline and kynurenine to tryptophan ratio: potential EED (environmental enteric dysfunction) biomarkers in acute watery diarrhea among children in Bangladesh.

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.

Factors associated with low and medium household dietary diversity compared with high dietary diversity among marginalised households in rural Bangladesh: Findings from a Suchana baseline survey.

OBJECTIVE: This study aimed to identify the associated factors of low and medium household (HH) dietary diversity (DD) compared with high DD among marginalised households in rural Bangladesh. METHODS: Through the Suchana baseline survey, data on 5440 households from Sylhet and Moulvibazar districts of Bangladesh was collected between November 2016 and February 2017. Household DD was categorised as low, medium or high based on number of food groups consumed during the last 24 hours. Primary outcome measure was household DD; multinomial logistic regression was to determine independent correlations between outcome and independent variables. RESULTS: Of the households examined, 0.72%, 31.8% and 67.5% had low, medium and high DD, respectively. Around 99% and 97% of households consumed cereals and vegetables. Cereals, fruits and legumes accounted for 36%, 18% and 16% of total food expenditure; vegetables only represented 8% of total expenditure; 70% of total monthly expenditure was on food items. Compared with high DD, low DD was significantly associated with severe food insecurity, not receiving remittance, not being supported by social safety-net programs, household size of 6-10, household income and expenditure on food below-median. Severe food insecurity was the strongest predictor of low DD. Age, occupation and educational status of the household head, amount of land owned and presence of a homestead garden, fish production and domestic violence were not significantly associated with DD. CONCLUSION: Our findings suggest that nine out of ten households were food insecure, and nearly two-thirds of households had high DD. Severe food insecurity was significantly associated with low DD. Expenditure on food items amounted to nearly two-thirds of total household expenditure. Diversification of income-generating activities would provide more sources of income to the households, allowing the households to spend more on non-cereal food items and increase the household dietary diversity.

Antimicrobial resistance in shigellosis: A surveillance study among urban and rural children over 20 years in Bangladesh.

Antimicrobial resistance against shigellosis is increasingly alarming. However, evidence-based knowledge gaps regarding the changing trends of shigellosis in Bangladesh exist due to the scarcity of longitudinal data on antimicrobial resistance. Our study evaluated the last 20 years antimicrobial resistance patterns against shigellosis among under-5 children in the urban and rural sites of Bangladesh. Data were extracted from the Diarrheal Disease Surveillance System (DDSS) of Dhaka Hospital (urban site) and Matlab Hospital (rural site) of the International Centre for Diarrheal Disease Research, Bangladesh (icddr,b) between January 2001 and December 2020. We studied culture-confirmed shigellosis cases from urban Dhaka Hospital (n = 883) and rural Matlab Hospital (n = 1263). Since 2001, a declining percentage of shigellosis in children observed in urban and rural sites. Moreover, higher isolation rates of Shigella were found in the rural site [1263/15684 (8.1%)] compared to the urban site [883/26804 (3.3%)] in the last 20 years. In both areas, S. flexneri was the predominant species. The upward trend of S. sonnei in both the study sites was statistically significant after adjusting for age and sex. WHO-recommended 1st line antibiotic ciprofloxacin resistance gradually reached more than 70% in both the urban and rural site by 2020. In multiple logistic regression after adjusting for age and sex, ciprofloxacin, azithromycin, mecillinam, ceftriaxone, and multidrug resistance (resistance to any two of these four drugs) among under-5 children were found to be increasing significantly (p<0.01) in the last 20 years in both sites. The study results underscore the importance of therapeutic interventions for shigellosis by appropriate drugs based on their current antibiogram for under-5 children. These observations may help policymakers in formulating better case management strategies for shigellosis.

Food security status of Suchana-participating households in north-eastern rural Bangladesh.

Despite achieving remarkable progress, food insecurity remains a major public health challenge in Bangladesh, and severe food insecurity status has not been reduced in susceptible areas and vulnerable regions in Bangladesh. Wetlands that are susceptible to flooding can be found in Bangladesh's north-eastern Sylhet division. Suchana, a large-scale nutrition programme, implemented nutrition-specific and sensitive interventions in poor and very poor households in Sylhet and Moulvibazar districts in the north-eastern region of Bangladesh. The aim of this article is to assess the association between the Suchana intervention and household food security status among poor and very poor households in north-eastern rural Bangladesh using the Suchana baseline and endline survey databases. The baseline survey was conducted between November 2016 and February 2017, while the endline survey was undertaken 3 years later, during the same months. The outcome variable in this analysis was household food security status, which was measured using the Food and Nutrition Technical Assistance's Guideline. Descriptive statistics were used to summarize the data; after controlling for the union as a cluster and relevant covariates, a multiple multinomial logistic regression model was used to estimate the independent effect of the Suchana intervention as an exposure. Overall, 14.0% of households were food secure at the baseline survey (intervention: 14.1%, control: 14.0%) and 22.0% were food secure (intervention: 26.6%, control: 20.2%) at the endline survey. For households in the intervention area in comparison to the control area, the odds of being moderately food insecure [aOR: 1.36 (1.05, 1.76), p < 0.05], mildly food insecure [aOR: 1.83 (1.33, 2.51), p < 0.001], or food secure [aOR: 2.21 (1.47, 3.33), p < 0.001] compared to being severely food insecure was significantly higher. Thus, we infer that the 3 years of Suchana intervention marginally increased household food security status among the socio-economically disadvantaged population in north-eastern rural Bangladesh. If concerns regarding gender equity, women's education, and income-generating activities are addressed, the population could experience even greater benefits in food security. In order to overcome these challenges, all stakeholders including programme implementers and policymakers should work together to implement the appropriate measures.

Effects of Moringa oleifera leaves on hemoglobin and serum retinol levels and underweight status among adolescent girls in rural Bangladesh.

Objectives: Moringa oleifera has been used for centuries due to its medicinal properties and health benefits. The plant has antifungal, anti-viral, and anti-inflammatory properties. We aimed to evaluate the effect of consumption of Moringa leaves, along with a regular diet on serum hemoglobin and retinol and underweight status among rural Bangladeshi adolescent girls. Methods: This school-based quasi-experimental study involved 226 adolescent girls (12-14 years-old). Intervention group (n = 113) received a meal comprising rice, concentrated dal, and fried potato with Moringa pakora (oil-fried snack); the control group (at a different school in an adjacent area with similar population demographics) received calorie-matched meal without Moringa pakora for 6 months. We used generalized liner regression (GLM) analysis, to explore the effect of the intervention among the groups between baseline and endline. Results: Mean age of the intervention and control groups were 12.7 ± 0.7 and 13.3 ± 0.8 years, respectively. After adjusting for maternal education, absenteeism, asset index, BMI-for-age Z-score, GLM regression showed significant positive changes in hemoglobin (intervention vs. control: coef = 0.41, P = 0.010) and serum retinol (coef = 0.27, P = 0.00). No significant changes in weight was observed between groups. Conclusion: Consumption of Moringa leaves has the potential to improving hemoglobin and serum retinol level and should be encouraged as regular diet.

Enhanced women's decision-making power after the Suchana intervention in north-eastern Bangladesh: a cluster randomised pre-post study.

OBJECTIVES: Women's decision-making power is a dimension of empowerment and is crucial for better physical and psychosocial outcomes of mothers. Suchana, a large-scale development programme in Bangladesh, actively provided social interventions on behaviour change communication to empower women belonging to the poorest social segment. This paper aims to assess the impact of the Suchana intervention on various indicators related to women's decision-making power. DESIGN, SETTING AND PARTICIPANTS: The evaluation design was a cluster randomised pre-post design with two cross-sectional surveys conducted among beneficiary women with at least one child aged <23 months from randomly selected poor or very poor beneficiary households in Sylhet division. OUTCOME MEASURE: Decision-making indicators included food purchases, major household purchases, food preparation, children's healthcare as well as women's own healthcare and visiting family and relatives. RESULTS: Our findings suggest that 45% of women were able to make decisions on food purchases, 25% on major household purchases, 78% on food preparation, 59% on children's healthcare, 51% on their own healthcare and 43% on visiting family and relatives at baseline in the intervention group, whereas the results were almost the same in the control group. In contrast, at the endline survey, the respective proportions were 75%, 56%, 87%, 80%, 77% and 67% in the intervention group, which were significantly improved when compared with the control group. The prevalence of those outcome indicators were 64%, 41%, 80%, 71%, 68% and 56%, respectively, in the control group. As per multiple logistic regression analysis and structural equation modelling, the Suchana intervention had a substantial influence on the latent variable of women's decision-making power. CONCLUSION: In terms of food purchases, major household purchases, children's healthcare, their own healthcare and visiting family and relatives, the Suchana intervention favourably influenced the decision-making power of rural women living in a vulnerable region of Bangladesh.

Factor associated with anthropometric failure among under-five Bengali children: A comparative study between Bangladesh and India.

BACKGROUND: Child undernutrition is a burden and the leading cause of child mortality in low-and middle-income countries like Bangladesh and India. Currently, this issue is a matter of great concern, inasmuch as achieving the Sustainable Development Goals (SDGs). The study intends to determine the factors of child undernutrition using a single composite index of anthropometric failure (CIAF) among the Bengali population. METHODS: Unit level data on 14055 under 5 children were extracted from the Bangladesh Demographic and Health Survey 2017-18 (BDHS) and the 4th National Family Health Survey of India (NFHS-4). To understand child undernutrition and generate CIAF, data on height-for-age (stunting), weight-for-height (wasting), and weight-for-age (underweight) were used by WHO guidelines. These three undernutrition indicators were combined into a single undernutrition indicator called anthropometric failure (anth-failure) using the CIAF concept. Explanatory factors of anth-failure included data on maternal health, socio-demographic and birth-related variables. Differences of frequency were determined by Z-proportional and Chi-square tests; predictors of anth-failure were determined by binary logistic regression. Cut off point of p-value was taken as 0.05 to test the significance. RESULTS: Inter-country disparities were revealed, about half of Bengali children in India and two-fifths in Bangladesh being prone to anth-failure. Stunting and underweight were more prevalent in both countries than wasting. Maternal undernutrition, lack of maternal education, and poor wealth index were common factors of anth-failure for both countries. Children in Bangladesh developed anth-failure after the end of breastfeeding period, indicating a lack of nutritious food. Lack of antenatal care was another significant factor in Bangladesh. In India, the first child suffered from anth-failure due to lack of maternal education. CONCLUSIONS: This study provides a better understanding of multifactorial impact on child undernutrition. It is proposed that the emphasis should be on initiatives that improve maternal education and nutrition, child food security, boost household wealth index, and enhance mothers' access to health care. The study strongly recommends that the governments of Bangladesh and India invest financially in preventing child malnutrition, which will contribute to achieving the first four SDGs.

Association between Pathogenic Variants of Diarrheagenic Escherichia coli and Growth in Children under 5 Years of Age in the Global Enteric Multicenter Study.

There is a lack of information highlighting associations between different pathogenic variants of diarrheagenic Escherichia coli and childhood growth. Pathogenic variants of E. coli from stool samples, collected from 22,567 children enrolled in the Global Enteric Multicenter Study from December 2007 to March 2011, were detected by real-time polymerase chain reaction. We estimated the associations of different pathogenic variants of diarrheagenic E. coli with child growth. The association between an explanatory variable and the outcome variable was assessed using multiple linear regression, where the dependent variables were height-for-age, weight-for-age, and weight-for-height z-scores, and the independent variable was the presence of different pathogenic variants of diarrheagenic E. coli. After adjusting for potential covariates, such as age, gender, diarrhea, breastfeeding status, mother's education, number of under-5 children, handwashing practice, handwashing material, source of drinking water, wealth index, available toilet facility, copathogens, comorbidity, time, and study site, the multivariable model identified a negative association between different pathogenic variants of diarrheagenic E. coli and child growth. Our analyses may provide the cornerstone for prospective epidemiologic investigation for the development of preventive measures for diarrheagenic E. coli and combat childhood undernutrition.
