A new study found congenital heart disease prevalence increased by 85% in adults and 22% in children between 1985 and 2000. Most heart defects cause blood to flow through the heart in an abnormal way or obstruct blood flow, leading to a major public health problem.
A recent study estimates that a similar flu pandemic to the 1918-1920 pandemic could claim 62 million lives worldwide. The majority of deaths would occur in developing countries, where per capita income is lower.
A pioneering study reveals that the world's wealthiest individuals hold disproportionately large amounts of wealth, with the top 10% owning 85% of global assets. The richest countries in North America, Europe, and Asia-Pacific contribute to this concentration of wealth.

The researchers emphasize the importance of secondary prevention measures for this population.
A new study finds that African-Americans are more likely to cohabit with and marry whites than black immigrants from the Caribbean and Africa. Interracial marriages among different racial groups remain low, but cohabitation rates are higher.

According to a study published in The Lancet, heartburn is more common in Western populations compared to non-Western populations. Lifestyle factors such as obesity and smoking contribute to the development of gastro-oesophageal reflux disease (GORD), which can lead to significant economic burdens.
A Mailman School of Public Health study reveals that even low doses of arsenic in drinking water can increase the risk of skin lesions. Researchers found that participants exposed to well water with arsenic concentrations as low as 50 ug/l were at higher risk, particularly men and those with normal body mass index.
A new study found that HIV infection rates among young non-Hispanic blacks are significantly higher than other racial groups, with a rate of 4.9 per 1,000 compared to 0.22 for all other races. The study suggests that segregation and differences in sexual networks contribute to the disparity.
Rates of hip bone loss increase with age among white and non-white men, particularly those over 75. Osteoporosis in men results from declining estrogen levels, leading to brittle bones prone to fracture. The study predicts a 56% increase in male osteoporotic fractures and associated costs by 2025.
A new study reveals that Korean-American smokers often prioritize social benefits over health risks, making it difficult for them to quit. The study suggests that culturally tailored programs are necessary to address these issues, taking into account language, intent, and social dynamics within the Asian American community.
A study analyzed data from over 35,975 individuals who underwent colonoscopy without detecting colorectal neoplasia. The results showed a significant decrease in colorectal cancer incidence at 6 months (31%) and persisted for more than 10 years.
