The study found that freestanding EDs are concentrated in areas with higher incomes, private insurance rates, and hospital ED presence. This suggests that they may not be expanding access to underserved populations as initially thought.
Researchers from UEA's School of Biological Sciences found that female birds are choosing busier breeding locations with more abundant males, leading to skewed sex ratios in small populations. These findings suggest that conservation efforts should focus on maintaining large populations with equal sex ratios.
A study published in PLOS Medicine found that Mexico's nonessential food tax led to a significant decline in energy-dense food purchases, primarily among low and medium SES households.

A recent study by Drexel University's Dornsife School of Public Health found that local health departments provide mental health care services to around 30-40% of their populations, with those that offer services being seven times more likely to address population-based mental illness prevention. Local health departments also have oppo...
Even before the Affordable Care Act (ACA), cancer survivors in non-expansion states had limited access to healthcare. The study analyzed data from the 2012 and 2013 Behavioral Risk Factor Surveillance System and found that these survivors were less likely to have a personal doctor, receive an annual checkup, or see a doctor due to cost.
A team of researchers found that current harvest levels for gray wolves in the Northern Rocky Mountains have led to decreased survival and reproduction rates. The study suggests that policies regulating wolf hunting are not sustainable and should be revised to prioritize population growth.
