National Prevalence of Diarrhea and Associated Factors Among Children Under Five in Afghanistan

Why It Matters

With more than one‑third of Afghan toddlers affected, diarrhea remains a major driver of child mortality and hampers progress toward health and development goals. Targeted public‑health actions can dramatically cut preventable deaths and improve long‑term human capital.

Key Takeaways

• 38% of Afghan children under five experienced diarrhea in 2022‑23.
• Risk peaks for children aged 6‑35 months.
• Maternal education and wealth reduce diarrhea odds.
• Open defecation raises odds by 19%.
• South and East regions face 1.5‑1.6× higher risk.

Pulse Analysis

Afghanistan’s child health landscape faces a stark challenge: over a third of children under five reported recent diarrhea, a prevalence far above the global average of roughly 15 %. This high burden reflects a confluence of demographic and environmental pressures, notably the vulnerability of infants transitioning to solid foods. As children enter the weaning window, exposure to contaminated water and inadequate hygiene practices spikes, driving the observed age‑related risk surge.

Statistical analysis links lower diarrhea odds to older maternal age, higher household income, and maternal schooling beyond primary level, underscoring the protective power of socioeconomic uplift. Conversely, households practicing open defecation face a 19 % increase in odds, while the South and East provinces experience 1.5‑1.6 times higher risk than the Central region. These geographic disparities point to uneven infrastructure development and highlight sanitation as a critical frontier for intervention.

Policy makers can leverage these insights by scaling infant and young‑child feeding programs, expanding girls’ education, and accelerating community‑based sanitation projects. Behavior‑change campaigns that promote safe weaning, hand‑washing, and latrine use could cut diarrhea incidence substantially, aligning with Sustainable Development Goal 3 targets. Focused investments in the high‑risk South and East zones promise the greatest return, potentially reducing child mortality, easing health‑system strain, and fostering a healthier future workforce.
