The study found that stroke incidence rates in urban Tanzania were almost three times higher than in rural areas, with crude yearly rates of 94.5 per 100,000 in rural Hai and 107.9 per 100,000 in urban Dar-es-Salaam. The authors suggest that undiagnosed or inadequately treated hypertension is a major modifiable risk factor for stroke i...

Researchers at the University of Sheffield have found that mortality rates from alcohol-related diseases are over four times higher in deprived areas compared to less deprived areas. Deaths from such diseases are increasing despite public awareness campaigns, highlighting the need for targeted policies to reduce harm caused by alcohol.
A new study suggests that painting building roofs white could reduce urban heat island effects by 33%, cooling cities by an average of 0.7 degrees F. However, the authors caution that actual use of white roofs would depend on various factors and may not be feasible due to wear and tear.

New USGS research shows that frog and toad abundance and species richness are low in urban areas but near normal in agricultural areas. The study also confirms the role of forests as important amphibian habitat, suggesting that habitat quality is crucial for these species.
Research suggests that strong traditional values among Southern Black women may be a key factor in lower smoking rates among African-Americans. The study found that Black adults in the non-urban South had the lowest smoking prevalence rates, with 11% of those aged 18-24 living smoke-free. This trend holds true for Southern Black women ...
A study by Stanley Changnon and colleagues found no evidence of an increase in catastrophic weather events, despite rising property losses. The growth of losses is attributed to the increasing population in coastal and urban areas, leading to a larger target-at-risk.
A recent USGS study has found that urban sprawl, not fire suppression, is largely responsible for the devastating wildfires in southern and central-coastal California. The researchers suggest that strategic management of buffer zones between urban lands and wildlands could help mitigate ecological impacts.
