Diarrhoeal children with concurrent severe wasting and stunting compared to severe wasting or severe stunting

Burden of Childhood Diarrhea and Its Associated Factors in Ethiopia: A Review of Observational Studies

Objectives: This systematic review and meta-analysis aimed to: i) determine the pooled prevalence of acute diarrhea; and ii) synthesize and summarize current evidence on factors of acute diarrheal illnesses among under-five children in Ethiopia. Methods: A comprehensive systematic search was conducted in PubMed, SCOPUS, HINARI, Science Direct, Google Scholar, Global Index Medicus, Directory of Open Access Journals (DOAJ), and the Cochrane Library. This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The methodological quality of each included article was assessed using the Joanna Briggs Institute (JBI) quality assessment tool for cross-sectional and case-control studies. A random-effect meta-analysis model was used to estimate the pooled prevalence of diarrheal illnesses. Heterogeneity and publication bias were assessed using I2 test statistics and Egger's test, respectively. The statistical analysis was done using STATA™ software version 14. Results: Fifty-three studies covering over 27,458 under-five children who met the inclusion criteria were included. The pooled prevalence of diarrhea among under-five children in Ethiopia was found to be 20.8% (95% CI: 18.69-22.84, n = 44, I2 = 94.9%, p < 0.001). Our analysis revealed a higher prevalence of childhood diarrhea in age groups of 12-23 months 25.42% (95%CI: 21.50-29.35, I2 = 89.4%, p < 0.001). In general, the evidence suggests that diarrheal risk factors could include: i) child level determinants (child's age 0-23 months, not being vaccinated against rotavirus, lack of exclusive breastfeeding, and being an under-nourished child); ii) parental level determinants {mothers poor handwashing practices [pooled odds ratio (OR) = 3.05; 95% CI:2.08-4.54] and a history of maternal recent diarrhea (pooled OR = 3.19, 95%CI: 1.94-5.25)}; and iii) Water, Sanitation and Hygiene (WASH) determinants [lack of toilet facility (pooled OR = 1.56, 95%CI: 1.05-2.33)], lack handwashing facility (pooled OR = 4.16, 95%CI: 2.49-6.95) and not treating drinking water (pooled OR = 2.28, 95% CI: 1.50-3.46). Conclusion: In Ethiopia, the prevalence of diarrhea among children under the age of five remains high and is still a public health problem. The contributing factors to acute diarrheal illnesses were child, parental, and WASH factors. A continued focus on improving access to WASH facilities, along with enhancing maternal hygiene behavior will accelerate reductions in diarrheal disease burden in Ethiopia.

Clinical and nutritional correlates of bacterial diarrhoea aetiology in young children: a secondary cross-sectional analysis of the ABCD trial

OBJECTIVE

The objective was to assess the association between nutritional and clinical characteristics and quantitative PCR (qPCR)-diagnosis of bacterial diarrhoea in a multicentre cohort of children under 2 years of age with moderate to severe diarrhoea (MSD).

DESIGN

A secondary cross-sectional analysis of baseline data collected from the AntiBiotics for Children with Diarrhoea trial (NCT03130114).

PATIENTS

Children with MSD (defined as >3 loose stools within 24 hours and presenting with at least one of the following: some/severe dehydration, moderate acute malnutrition (MAM) or severe stunting) enrolled in the ABCD trial and collected stool sample.

STUDY PERIOD

June 2017-July 2019.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Likely bacterial aetiology of diarrhoea. Secondary outcomes included specific diarrhoea aetiology.

RESULTS

A total of 6692 children with MSD had qPCR results available and 28% had likely bacterial diarrhoea aetiology. Compared with children with severe stunting, children with MAM (adjusted OR (aOR) (95% CI) 1.56 (1.18 to 2.08)), some/severe dehydration (aOR (95% CI) 1.66 (1.25 to 2.22)) or both (aOR (95% CI) 2.21 (1.61 to 3.06)), had higher odds of having likely bacterial diarrhoea aetiology. Similar trends were noted for stable toxin-enterotoxigenic Escherichia coli aetiology. Clinical correlates including fever and prolonged duration of diarrhoea were not associated with likely bacterial aetiology; children with more than six stools in the previous 24 hours had higher odds of likely bacterial diarrhoea (aOR (95% CI) 1.20 (1.05 to 1.36)) compared with those with fewer stools.

CONCLUSION

The presence of MAM, dehydration or high stool frequency may be helpful in identifying children with MSD who might benefit from antibiotics.

Etiology of diarrheal hospitalizations following rotavirus vaccine implementation and association of enteric pathogens with malnutrition among under-five children in India

Malnourished children are at higher risk of mortality and morbidity following diarrheal illness and certain enteropathogens have been associated with malnutrition in children. Very few studies have comprehensively looked at the etiology of diarrhea in malnourished children and most have used conventional diagnostic methods with suboptimal sensitivity. We used a highly sensitive molecular approach against a broad range of pathogens causing diarrhea and examined their association with malnutrition. In addition, we looked at the pathogen diversity of pediatric diarrhea, three years after the nationwide rotavirus vaccine introduction to understand the evolving landscape of pathogens, which is crucial for planning strategies to further reduce the diarrhea burden. Clinical details and diarrheal stool samples were collected from hospitalized children aged < 5 years from three sentinel sites in India for a period of one year. The samples were tested by qPCR for 16 established causes of diarrhea using TaqMan Array Cards. A total of 772 children were enrolled, from whom 482 (62.4%) stool specimens were tested. No specific pathogen was associated with diarrhea among children with acute or chronic malnutrition compared to those with better nutritional status. Overall, adenovirus was the leading pathogen (attributable fraction (AF) 16.9%; 95% CI 14.1 to 19.2) followed by rotavirus (AF 12.6%; 95% CI 11.8 to 13.1) and Shigella (AF 10.9%; 95% CI 8.4 to 16.4). The majority of diarrhea requiring hospitalization in children aged < 2 years could be attributed to viruses, while Shigella was the most common pathogen among children aged > 2 years. These data on the prevalence and epidemiology of enteropathogens identified potential pathogens for public health interventions.

Concurrent wasting and stunting among marginalised children in Sana'a city, Yemen: a cross-sectional study

Concurrent wasting and stunting (WaSt) is a serious form of malnutrition among young children, particularly vulnerable groups affected by the conflict. Understanding the prevalence and risk factors of WaSt among vulnerable children is important to develop effective intervention measures to reduce the burden of WaSt. The present study aimed to identify the prevalence of and risk factors for WaSt among marginalised children aged 6-59 months in Sana'a city, Yemen. A community-based cross-sectional design was conducted on a total sample size of 450 marginalised children aged 6-59 months who lived at home with their mothers. Multivariable logistic regression analysis was performed and the prevalence of WaSt was found to be 10⋅7 %. Children aged 24-59 months were protected from WaSt (adjusted odds ratio (AOR) 0⋅40, 95 % confidence interval (CI) 0⋅21, 0⋅75). A higher prevalence of WaSt was associated with male sex (AOR 2⋅31, 95 % CI 1⋅13, 4⋅71), no history of being breastfed (AOR 3⋅57, 95 % CI 1⋅23, 10⋅39), acute diarrhoea (AOR 2⋅12, 95 % CI 1⋅12, 4⋅02) and family income sources of assistance from others (AOR 2⋅74, 95 % CI 1⋅08, 6⋅93) or salary work (AOR 2⋅22, 95 % CI 1⋅10, 4⋅47). Continued breast- and bottle-feeding were not associated with WaSt in children aged 6-23 months. Mothers' age, education and work status, family size and drinking water source were not associated with WaSt. Overall, we found that the prevalence of WaSt among marginalised children remained high. Interventions to improve household income, hygienic conditions and child feeding practices are necessary to promote child growth.

Predictors of diarrhea among children under 24 months in Nepal: A multilevel analysis of multiple indicator cluster survey 2019

BACKGROUND

Diarrhea has remained an unmet challenge in global child health. Its severity may be worse than reported in resource-limited settings. Understanding changing epidemiology is critical to combat diarrheal morbidity. Therefore, this study aimed to understand factors associated with diarrhea among under two years children in Nepal.

METHODS

A total of 2,348 samples from Multiple Indicator Cluster Survey 2019 were used to estimate the significant child, maternal, household and external environmental predictors of diarrhea using multilevel analysis.

RESULTS

The prevalence of diarrhea was 11.9% (95% CI: 10.2%-13.6%). Children residing in Koshi Province [AOR (Adjusted Odds Ratio): 2.23, 95% CI: 1.22-4.08], Karnali Province (AOR: 2.28, 95% CI: 1.11-4.70), and Sudurpaschim Province (AOR: 4.49, 95% CI: 2.39-8.42) were at higher risk of diarrhea. Children aged 7-23 months (AOR: 1.56, 95% CI: 1.10-2.20), children with ARI symptoms (AOR: 4.14, 95% CI: 2.21-7.72) and children whose mothers had no access to prenatal care (AOR: 1.87, 95% CI: 1.01-3.45) had a higher risk of diarrhea. Children from below the richest household wealth group (AOR: 1.76, 95% CI: 1.01-3.08) and those from households practicing open defecation, with unimproved or limited sanitation facilities (AOR: 1.52, 95% CI: 1.09-2.11) were more likely to have diarrhea.

CONCLUSION

The findings underscore the need for public health policy-makers to improve sanitation facilities, especially focusing on poor households from Karnali and Sudurpaschim Provinces practicing open defecation to protect the children from the life risk of diarrhea in Nepal.

Prevalence and determinants of concurrent wasting and stunting and other indicators of malnutrition among children 6-59 months old in Kersa, Ethiopia

Malnutrition is the leading cause of poor child health in Ethiopia, and progress to avert it is unacceptably slow. In addition, little is known about the magnitude and factors associated with concurrent wasting and stunting (WaSt). Therefore, this study aimed to assess the prevalence and factors associated with WaSt, wasting, stunting and underweight among children 6-59 months in Kersa Health and Demographic Surveillance System, Ethiopia. Data from a total of 1091 children and their parents' were analysed from a cross-sectional study. Household questionnaires and anthropometric measurements were used for data collection. Height-for-age, weight-for-height and weight-for-age indices are expressed as standard deviation units from the mean for the reference group. Multivariate analyses were conducted to identify factors associated with WaSt, wasting, stunting and underweight. Statistical significance was declared at p < 0.05. The prevalence of indicators of malnutrition was WaSt (5.8%), wasting (16.8%), stunting (53.9%) and underweight (36.9%). Children aged 6-17 months had a higher odds of wasting (adjusted odds ratio [aOR] 1.8, 95% confidence interval [CI] 1.12-2.75) compared with those aged 36-59 months, whereas children aged 18-35 months (aOR 2.4, 95% CI 1.65-3.47) and 36-59 months (aOR 1.6, 95% CI 1.07-2.37) had higher odds of stunting compared with those aged 6-17 months. Similarly, children aged 18-35 months (aOR 1.6, 95% CI 1.07-2.37) and 36-59 months (aOR 2.2, 95% CI 1.52-3.10) had higher odds of underweight compared with children aged 6-17 months. Households that did not treat drinking water at point of use were at higher odds of WaSt (aOR 3.3, 95% CI 1.16-9.27) and stunting (aOR 1.9, 95% CI 1.31-2.85) compared with those who did treat drinking water. Boys were more likely to be WaSt, wasted, stunted and underweight. Cough was associated with WaSt, wasting and underweight. Furthermore, maternal education, maternal occupation and maternal age were significantly associated with wasting. Maternal body mass index (BMI) of less than 18.5 kg/m² and maternal BMI between 18.5 and 25 kg/m² were associated with child stunting. In Kersa, the prevalence of WaSt, wasting, stunting and underweight is very high and requires urgent public health intervention. This study highlights point-of-use water treatment, maternal education, hygiene and sanitation, child health service utilization and maternal BMI as important areas to improve to target child malnutrition. Furthermore, a community-based programmatic and policy direction for early identification and management of WaSt in addition to other indicators of malnutrition is recommended.
