The heat is on — and it's hitting the most vulnerable hardest. WHO, WMO, UNICEF, and UNFPA have jointly launched the first-ever set of priority indicators to help countries monitor how extreme heat affects pregnant women, newborns, and children. The framework aims to strengthen preparedness and response as rising global temperatures drive surging risks of preterm birth, stillbirth, and child illness worldwide.
Four major global health organizations — WHO, WMO, UNICEF, and UNFPA — have joined forces to release the first standardized set of priority indicators designed to help countries track the health impacts of extreme heat on pregnant women, newborns, and children. The framework is a direct response to mounting evidence that rising temperatures are creating serious, measurable harm for some of the world's most vulnerable populations.
The new guidance calls on countries to routinely monitor outcomes like preterm births, stillbirths, low birthweight, pregnancy hypertension, child deaths, and health-facility visits during heat events. Even school attendance is flagged as a useful proxy for heat's broader disruption to children's lives.
Why it matters: Without consistent data, health systems can't respond effectively. This framework gives governments the tools to identify at-risk communities, strengthen early warning systems, and build heat-health action plans that specifically protect pregnant women, newborns, and children — before the next heatwave hits.
