Interventions to address unsafe child feces disposal practices in the Asia-Pacific region: a systematic review

Abstract

Despite clear evidence of the adverse health impacts of unsafe child feces disposal (CFD), there is little evidence of the effectiveness of interventions targeting the improvement of unsafe CFD practices in this region. A systematic review of the literature was conducted to identify and evaluate the quality of both behavior change and hardware interventions targeting the improvement of CFD practices in the Asia-Pacific region. A total of 695 articles were screened, and 11 studies were included. The combined hardware and behavior change interventions reported the highest rates of safe CFD (SCFD) post-intervention; however, these interventions were of lower quality. Four interventions focused specifically on improving SCFD practices, while the remaining seven studies evaluated the impacts of large-scale interventions, such as India's MANTRA and Total Sanitation Campaign programs, on unsafe CFD practices. Large-scale programs and hardware interventions are important for providing communities with the infrastructure necessary to improve unsafe CFD practices, but such interventions may be improved by the addition of a behavioral change component. With little evidence available on the effectiveness of behavioral interventions on reducing unsafe CFD in the Asia-Pacific region, future work should focus on how behavior change models combined with hardware interventions impact unsafe CFD.

Does owning improved latrine facilities enhance the safe disposal of child feces in Africa? a systematic review and meta-analysis

“…Even so, open disposal was still common in homes with toilets. According to a systematic review conducted in the Asia-Pacific area, these results point to the importance of putting large-scale programs and hardware interventions into place in order to give communities the tools they need to modify their habits and behaviors in the presence of improved latrine [ 43 ].…”

Faecal sludge emptying in Sub-Saharan Africa, South and Southeast Asia: A systematic review of emptying technology choices, challenges, and improvement initiatives

“…In this review, PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines (Moher et al, 2009;Sprouse et al, 2022) were followed to identify all the relevant publications pertaining to FS emptying in Sub-Saharan Africa (SSA), South Asia and Southeast Asia. These regions were chosen because of their wide coverage with OSS and in turn widely spread emptying businesses (Tremolet, 2012).…”

Effectiveness of the Swachh Bharat Mission and barriers to ending open defecation in India: a systematic review

“…Open defecation (OD) refers to the practice of defecating or disposing of human feces in fields, forests, bushes, bodies of water, or other open spaces (WHO and UNICEF, 2021). Given its linkages to human health, dignity, and gender equity, eliminating OD has remained a global goal and water, sanitation, and hygiene (WASH) sector priority (Beardsley et al, 2021;Sprouse et al, 2022) manifesting in an international agreement on the human right to water and sanitation and the United Nations SDG 6.2 to achieve by 2030 access to adequate and equitable sanitation and hygiene for all and end OD (United Nations, 2022). Between 2000 and 2020, the World Health Organization/United Nations Children's Fund Joint Monitoring Programme (JMP) reported that the proportion of the global population practicing OD decreased from 21% to 6%; however, an estimated 494 million people still practice OD, of whom 90% live in rural areas of sub-Saharan Africa and Central and Southern Asia (WHO and UNICEF, 2021).…”
