In July 2026 UNICEF warned that around 40 % of Mexican children are overweight or obese while about 15 % suffer from malnutrition, and noted that exclusive breastfeeding rates remain low at roughly 34 % of infants under six months. The agency called for stricter regulation of child‑focused marketing, improvements to food systems and policies that support mothers, such as flexible work hours and lactation spaces. By early August, state health officials reported that 30‑40 % of schoolchildren in Querétaro are overweight or obese, matching the national survey. In Chihuahua, 1,156 new obesity cases were recorded among children and adolescents aged 5‑14, with the majority concentrated in Ciudad Juárez and the city of Chihuahua. The regional "Vive Saludable, Vive Feliz" program identified excess weight as the main health problem and urged families to improve nutrition, increase physical activity and limit screen time. These reports reinforce the earlier concerns and highlight the need for coordinated public‑health actions across Mexico. ## Timeline ### 2026-08-02: Mexico's Child Obesity Affects 30‑40% of Schoolchildren, Peaks in Chihuahua In Mexico, 30‑40% of schoolchildren in Querétaro are overweight or obese, while Chihuahua reports 1,156 new child obesity cases, most in Ciudad Juárez and Chihuahua city, prompting health officials to urge more 2 sources. https://clstr.news/cluster/mexicos-child-obesity-affects-3040-of-schoolchildren-peaks-in-chihuahua ### 2026-07-20: Mexico faces dual child nutrition crisis as obesity rises and breastfeeding rates lag UNICEF reports 40% of Mexican children are overweight and 15% malnourished; exclusive breastfeeding rates sit at 34%, prompting calls for stronger health policies. 7 sources. https://clstr.news/cluster/mexico-faces-dual-child-nutrition-crisis-as-obesity-rises-and-breastfeeding-rates-lag --- Cite as: Mexico child nutrition crisis.
