Study Reveals Diarrhoea–Malnutrition Hotspots in East Africa

Thousands of East African children are facing a dangerous double health threat, suffering from both diarrhoea and severe malnutrition at the same time

Thousands of East African children are facing a dangerous double health threat, suffering from both diarrhoea and severe malnutrition at the same time, according to a new regional study published in Scientific Reports, raising concerns about child survival and targeted health interventions.

The research, which analyzed data from 11 countries including Uganda, Ethiopia, and Tanzania, focused on children aged 6 to 24 months. It found that about three percent of children in this age group experience both diarrhoea and wasting simultaneously, a condition experts say significantly increases the risk of death and long-term developmental problems.

Researchers warn that the combination is particularly dangerous because each condition worsens the other. “Concurrent diarrhoea and wasting (DW) among children aged 6–24 months represents a critical public health threat in East Africa,” the study notes.

Using advanced mapping and statistical tools, the study identified specific “hotspots” where the problem is most severe. These include parts of Ethiopia, Uganda, Rwanda, Burundi, and Tanzania, among others. The findings show that the issue is not evenly spread across the region, but rather concentrated in certain locations due to social and environmental factors.

Experts say this uneven distribution is key to understanding why previous interventions have had limited success. “Spatial variations… indicate disparities in sociocultural, economic, and health service domains,” the researchers explain in the paper. 

The study highlights several major drivers behind the condition. Poor access to clean water and sanitation remains one of the biggest risk factors, exposing children to infections that lead to diarrhoea. Low levels of maternal education were also strongly linked to higher cases, particularly in countries like Uganda and Rwanda, where mothers may have limited access to health information.

Other contributing factors include delayed breastfeeding after birth, poverty, and even the child’s sex, with boys found to be more vulnerable in some regions. Health experts say these findings point to the need for more targeted and localised interventions rather than broad, one-size-fits-all policies.

The study argues that better data and mapping can help governments respond more effectively. “Without spatial intelligence, DW hotspots evade targeted control, perpetuating 25–35% preventable child deaths,” the study warns.
