The Swaziland HIV Incidence Measurement Survey found that HIV prevalence has stabilized over the past five years, with current prevalence peaking at 54% for women ages 30-34 and 48% for men ages 35-39. The survey also indicates declines in HIV prevalence among young adults, which may suggest a reduction in new HIV infections.

Women over 50 years old are more likely to discontinue medication or not take it as prescribed if co-payments exceed $30.
A recent study by Columbia University's Mailman School of Public Health found that people with alcohol disorders are 60% less likely to seek treatment if they perceive negative stigma. Younger individuals, men, and those with lower income reported higher levels of stigma, leading to reduced treatment utilization.
A study by Columbia University's Mailman School of Public Health found that the US life expectancy has fallen behind other countries despite high health spending. The researchers attribute this failure to flaws in the overall healthcare system, including unregulated fee-for-service payments and reliance on specialty care.
A recent study found that less than half of essential workers are willing and able to report to work during a serious pandemic. Motivation to work is tied to workplace safety measures, trust in employers, and past experience. Employers can increase worker willingness by providing resources and support for personal obligations.
A study by Columbia University's Mailman School of Public Health found that nearly all NYC public school students have access to convenient, energy-dense foods within a short walk. Small grocery stores and bodegas are common sources of unhealthy food, with higher concentrations near schools attended by low-income and minority students.
A new study found that children treated with protease inhibitors and then switched to Nevirapine were more likely to maintain low virus levels. The switch regime is easier for parents to adhere to, saving money, but requires adequate monitoring of virus levels.
Researchers at Columbia University's Mailman School of Public Health found a high prevalence of PTSD nearly two decades after the Liberian civil war, with certain villages experiencing a higher burden of trauma. The study suggests that populations exposed to severe conflict are likely to bear a long-lasting psychological toll.
