Lancet: Study on diarrhoea burden and risk factors in children in low- and middle-income countries

In low- and middle-income countries (LMICs), one in ten children under five years of age dies from diarrhoeaDiarrhoea morbidity and mortality vary widely between countries, and researchers recently examined the risk factors associated with countries with the highest burden of diarrhoearesearchers used a Bayesian model dataset of 466 studies of 94 LMICs, comprising 1507,2746 children under the age of 5, combined with the results of the 2017 Global Study of Disease, Injury and Risk Factors (GBD), to estimate diarrhoea prevalence, morbidity and mortality rates in countries from 2000 to 2017Based on these data, the researchers used spatial aggregationtos to map the burden of diarrhea at sub-levels of different countries( known as units) and to estimate risk factors by creating aggregaterisk risk factorsstudy found that the regions with the largest declines in diarrhoeal mortality were south, South-East Asia and South America, with 54.0 per cent, 17.4 per cent and 59.5 per cent, respectively, with a decline of more than 10 per centAlthough children in most parts of Africa still face a higher risk of diarrhoeal deaths, the region with the highest death toll is not In Africa, with the highest mortality units being in PakistanThe internal disparities are most pronounced in Indonesia, where mortality rates are almost four times the national average in some areasReduced mortality rates are associated with improvements in water, hygiene and personal hygiene (WASH) or reductions in child growth failure (CGF)Similarly, wash is poor in most high-risk areas, high CGF or low oral rehydration treatment coverageby analyzing geospatial trends in the burden of diarrhoea and its main risk factors, researchers can assess risk factors for diarrhoea death in all regions of the country, and given the limited resources of low- and middle-income countries, it is important to accurately quantify the burden of diarrhoea and its drivers for accurate public health
