Diarrhoea remains one of the most serious health threats to young children in the Global South, and new research shows that climate change is set to worsen the risk substantially. However, improved access to education and targeted health policies could help families protect their children from this deadly disease.

Regular walking is widely recognized for its significant benefits to overall health and well-being. Previous research has primarily focused on middle-to-high-income White populations. Now, a novel analysis using data from the Southern Community Cohort Study, involving 79,856 predominantly low-income and Black individuals across 12 southeastern US states, confirms the benefits of regular walking, especially at a faster pace, within a crucial, underrepresented group. The new study appearing in the American Journal of Preventive Medicine, published by Elsevier, underscores the importance of promoting walking, particularly at a brisk pace, as an effective form of physical activity for improving health.
