Background <p>The burden of childhood diarrhoeal disease is high among the country's tribal population, and appropriate management is crucial in reducing that burden. Appropriate management will not only reduce diarrhoea-associated morbidity and mortality in tribal children but also contribute to achieving the SDG target of ending preventable mortality in under-5&#xa0;year children. Accordingly, the paper makes an attempt to carry out a pan-country level assessment of diarrhoea management behaviour and practices among the caregivers of under 5-year children with diarrhoea in tribal areas.</p> Methods <p>The paper is based on the data collected under the two rounds of the National Family Health Survey (NFHS), namely, NFHS-4 (2015–2016) and NFHS-5 (2019–2021). These are large-scale and periodic surveys that are conducted under the aegis of the Ministry of Health and Family Welfare, Government of India, on representative samples of households in the country. Data on various aspects of diarrhoea management were extracted out for 67,412 children who were included in our study and analysed to examine the status quo and progress made in diarrhoea management in the under 5-year children in tribal areas of the country.</p> Results <p>Between 2015 and 2021, there was a noticeable decline in diarrhoeal cases, with substantial progress made in diarrhoea management in tribal areas of the country. The diarrhoeal cases declined from 7.2% in 2015 to 6.4% in 2021 (p &lt; 0.001). The ORS usage increased from 61% in 2015 to 68% in 2021 (p &lt; 0.008), while the zinc usage increased from 26% to 39% (p &lt; 0.001) during the same time period. The ORS usage is close to 68% in tribal areas, which is more than the national average (61%). However, the district-level variations in coverage and less-than-usual liquid/food feeding are concerning. The improvement in hand-washing behaviours is also significant. The households where water was available for hand-washing increased from 68% in 2015 to 83% in 2021 (p &lt; 0.001), and households with soap availability increased from 44% in 2015 to 62% in 2021 (p &lt; 0.001).</p> Conclusion <p>Progress in childhood diarrhoea management among the tribal population of the country is evident, with more caregivers engaging in appropriate practices. The progress is quite encouraging and sustained improvements could support the efforts being made to achieve the SDG target of zero preventable deaths under 5&#xa0;years of age in the country.</p>
