Water, sanitation and hygiene interventions and the prevention and treatment of childhood acute malnutrition: A systematic review

Household-level water, sanitation and hygiene factors and interventions and the prevention of relapse after severe acute malnutrition recovery: A systematic review

Severe acute malnutrition (SAM) is the most serious form of acute malnutrition and is associated with high mortality risk among children under 5. While the Community-based Management of Acute Malnutrition (CMAM) approach, recommended for treating cases of uncomplicated SAM, has increased treatment coverage and recovery outcomes, high relapse rates have been reported. Several risk factors for SAM relapse, such as insufficient food intake and high infectious disease burden in the community, have been identified. However, the role of household water, sanitation and hygiene (WASH) conditions remains unclear. This systematic review: (1) assesses the effectiveness of WASH interventions on preventing SAM relapse and (2) identifies WASH-related conditions associated with relapse to SAM among children aged 6-59 months discharged as recovered following SAM CMAM treatment. We performed electronic searches of six databases to identify relevant studies published between 1 January 2000 and 6 November 2023 and assessed their quality. After deduplication, 10,294 documents were screened by title and abstract, with 13 retrieved for full-text screening. We included three studies ranging from low- to medium-quality. One intervention study found that providing a WASH kit during SAM outpatient treatment did not reduce the risk of relapse to SAM. Two observational studies found inconsistent associations between household WASH conditions-unimproved sanitation and unsafe drinking water-and SAM relapse. Despite the paucity of evidence, the hypothesised causal pathways between WASH conditions and the risk of relapse remain plausible. Further evidence is needed to identify interventions for an integrated postdischarge approach to prevent relapse.

Prevalence of Acute Malnutrition and Associated Factors among Children aged 6-59 months in South Wollo Zone, East Amhara, Northeast Ethiopia: a Community-based cross-sectional study

OBJECTIVE

The aim of this study is to determine the prevalence of acute malnutrition and associated factors in South Wollo zone, East Amhara, Northeast Ethiopia.

DESIGN

A community-based cross-sectional study was conducted among 504 children aged 6-59 months who were selected by using a multistage sampling technique. The mid-upper-arm-circumference and Z-scores for weight-for-height were used to determine the nutritional status of the participants. A semi-structured interview questionnaire was used to collect the data. Then data was entered into EpiData V.3.1 and exported to SPSS software V.25 for analysis. Binary logistic regression was used to identify factors associated with acute malnutrition and variables with p value<0.05 were declared as statistically significant.

SETTING

The study was conducted in South Wollo zone, Northeast Ethiopia from 1 August 2020 to 30 September 2020.

PARTICIPANTS

Children aged 6-59 months with their mothers were the study subjects.

RESULTS

The prevalence of acute malnutrition among children aged 6-59 months was 31.0%. Child aged 6-11 months (adjusted OR (AOR)=3.92; 95% CI: 1.74 to 8.82), illiterate mothers (AOR=3.01; 95% CI: 1.92 to 7.01), single mother (AOR=3.06; 95% CI: 1.32 to 7.07), lack of latrine (AOR=2.39; 95% CI: 1.12 to 5.11), diarrhoea (AOR=4.18; 95% CI: 2.02 to 8.65), respiratory tract infection (AOR=2.31; 95% CI: 1.08 to 4.94), family size (≥5) (AOR=3.29; 95% CI: 1.53 to 7.09) and cessation of breast feeding before 2 years (AOR=3.79; 95% CI: 1.71 to 8.23) were the independent predictors of acute malnutrition.

CONCLUSION

Acute malnutrition is highly prevalent in the study area which is more than the national figure. Thus, improving maternal education, access to the latrine, improved breastfeeding practice, improved family planning usage and early detection and treatment of diarrhoea and respiratory tract infections will enhance children's nutritional status. In addition, nutritional diversity education needs to be strengthened.

Prevalence and multi-level factors associated with acute malnutrition among children aged 6-59 months from war affected communities of Tigray, Northern Ethiopia, 2021: a cross-sectional study

BACKGROUND

Armed conflicts greatly affect the health, nutrition, and food security of conflict affected settings particularly children. However, no empirical data exist regarding context specific factors contributing towards acute malnutrition in the war-torn Tigray, Ethiopia. Thus, this study aimed to identify individual and community level factors associated with acute malnutrition among children aged 6-59 months from armed conflict affected settings of Tigray, Ethiopia.

METHODS

A community based cross-sectional study was conducted among 3,614 children aged 6-59 months in Tigray, from July 15 to Aug 15, 2021. Study participants were selected using a two-stage random sampling method. A structured questionnaire was used to collect data by interviewing mothers/caregivers. Mid upper arm circumference (MUAC) measurements were taken from upper left arm of the children using MUAC tapes. Multivariable multilevel logistic regression analysis was used to determine factors associated with acute malnutrition. Adjusted Odds ratio (AOR) with 95% CI were estimated to describe the strength of associations at p < 0.05.

RESULTS

More than half (52.5%) of the sampled children were males in sex. Immediately after the first nine months into the conflict, the prevalence of severe, moderate, and global acute malnutrition was very high (5.1%, 21.8%, and 26.9%, respectively) in Tigray. The lowest and highest burden of child acute malnutrition was reported from Mekelle zone (13.3%) and Southeastern zone (36.7%), respectively. Individual-level factors such as older child age (AOR = 0.13, 95% CI: 0.10, 0.18), female child sex (AOR = 1.24, 95% CI 1.05, 1.480.95), Vitamin-A supplementation (AOR = 1.3, 95% CI: 1.05, 1.65), and history of diarrhea (AOR = 1.22, 95%CI: 1.02, 1.53) and community-level factors like unimproved drinking water source (AOR = 1.31, 95%CI: 1.08, 1.58), unimproved toilet facility (AOR = 1.24, 95% CI: 1.01, 1.52), and severe food insecurity (AOR = 1.55, 95% CI: 1.16. 2.07) were significantly associated with childhood acute malnutrition.

CONCLUSIONS

The burden of acute malnutrition is a severe public health problem in Tigray. To prevent the untimely suffering and death of children, regular nutrition screening, speedy, and appropriate referral of all malnourished children to nutritional services and large-scale humanitarian assistance including access to food; nutrition supplies; water, sanitation and hygiene supplies; and health care in a timely manner are required. In the prevailing armed conflict, these have been very difficult to achieve. Thus, immediate international intervention is needed.

Associations of Nutritional Status with Full Immunization Coverage and Safe Hygiene Practices among Thai Children Aged 12–59 Months

Prevailing prevention measures against morbidity, such as vaccination and safe hygiene practices, vary among local cultural contexts, and little is known about the extent to which these behaviors mitigate poor nutritional status in young children in Southeast Asia. We examined the associations between nutrition status with full immunization coverage, and water, sanitation and hygiene status among children aged 12–59 months in the 2015–2016 Thailand Multiple Indicator Cluster Survey (n = 9060). When adjusted for confounding factors, children with incomplete immunization status were more likely to be stunted (adjusted odds ratio (aOR) 1.47; 95% confidence interval (CI): 1.24–1.75, p < 0.001), wasted (aOR 1.67, 95% CI: 1.31–2.12, p < 0.001), and overweight (aOR 1.24, 95% CI: 1.01–1.51, p < 0.05), whereas children who used unimproved water sources were more likely to be overweight (aOR 2.43, 95% CI: 1.27–4.64, p < 0.01). The further implementation of simple and cost-effective health promotion activities and practices at the household level may be important interventions for healthy child growth and development, particularly under restricted living conditions due to COVID-19.
