“…This may be because unprotected springs may be subject to faecal contamination, which is associated with child diarrhoea (Goddard et al, 2020). Also, WASH conditions vary from one setting to another, which may limit the approach (Pickering et al, 2019;Stoler et al, 2023). The WASH Benefits and Sanitation Hygiene Infant Nutrition Efficacy trials found that basic household-level WASH interventions had no effect on childhood linear growth and mixed effects on childhood diarrhoea (Humphrey et al, 2019;Luby et al, 2018;Null et al, 2018).…”

“…Such findings can be leveraged to inform nutrition‐sensitive services delivered post‐discharge. In addition, other outcomes, such as direct measurement of enteropathogenic infection, may be considered in future studies to capture a broader range of health benefits produced by WASH interventions, in line with the ‘transformative WASH’ approach (Pickering et al, 2019 ; Stoler et al, 2023 ). The WASH Benefits and Sanitation Hygiene Infant Nutrition Efficacy trials found that basic household‐level WASH interventions had no effect on childhood linear growth and mixed effects on childhood diarrhoea (Humphrey et al, 2019 ; Luby et al, 2018 ; Null et al, 2018 ).…”

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.
