Residential greenness and incident type 2 diabetes: A large prospective cohort study in China integrating evidence from 17 global cohorts.

Higher residential greenness is associated with a 6.1% reduction in type 2 diabetes risk in a Chinese cohort of nearly 6 million adults.

• Why it matters: Understanding environmental factors like greenness can help address the global rise in type 2 diabetes and inform urban planning and public health strategies.
• What they did: The study analyzed data from 5.87 million adults using vegetation indices and statistical models, supplemented by a systematic review of 17 global cohorts to validate findings.
• The result: Results indicate that increased greenness correlates with lower T2D incidence, especially among younger, women, urban, and educated groups, highlighting potential pathways for prevention.
