Faster Mass Vaccination Response Could Save Lives, Costs in a Flu Pandemic
A faster response of mass vaccinations after the start of a severe flu outbreak would save both lives and health care costs, according to a new study in Annals of Internal Medicine. Researchers created a computer model of a how an outbreak of H7N9 or H5N1 would affect a U.S. metropolitan city with characteristics similar to New York City, depending on when public health officials were able to vaccinate 30 percent of the population. They determined that reaching that vaccination target in 12 months would mean 48,254 persons would die; at 9 months would save an additional 2,365 lives; at 6 months would save an additional 5,775 lives and $51 million at a city level; and at 4 months would save an additional 5,633 lives and $50 million.

Study: Current Weight at 25 a Better Indicator of Later Obesity Risk than Duration of Obesity
In a study of the relationship between body mass index (BMI) at age 25, obesity later in life and biological indicators of health, researchers determined current weight—and not the duration of obesity—was a more effective indicator of cardiovascular and metabolic risk, according to a new study in the American Journal of Preventive Medicine. They did also note that people who were obese by age 25 were in fact at higher risk of more severe obesity later in life. Using data from the 1999-2010 U.S. National Health and Nutrition Examination Survey (NHANES), the study found that men who were obese at age 25 had a 23.1 percent estimated probability of class III obesity (BMI greater than 40) after age 35, compared to a 1.1 percent chance for men of a normal weight at age 25. For women who were obese at age 25 the risk of later class III obesity was 46.9 percent, compared to only 4.8 percent for women of a normal weight. “This is good news in some respects, as overweight and obese young adults who can prevent additional weight gain can expect their biological risk factors to be no worse than those who reach the same level of BMI later in life,” said study lead author Jennifer B. Dowd, MD, associate professor, epidemiology and biostatistics, City University of New York (CUNY) School of Public Health, Hunter College. Read more on obesity.
Higher High School GPAs Linked to Greater Earnings in Adulthood
A one-point increase in high school grade point average (GPA) can raise annual earnings in adulthood by approximately 12 percent for men and 14 percent for women, according to a new study in the Eastern Economic Journal. Researchers also determined that a 1-point increase in GPA increased the likelihood of completing college from 21 percent to 42 percent for both genders. “Conventional wisdom is that academic performance in high school is important for college admission, but this is the first study to clearly demonstrate the link between high school GPA and labor market earnings many years later,” said Michael T. French, director of the Health Economics Research Group (HERG) in the Department of Sociology at the UM College of Arts and Sciences, and corresponding author of the study, adding, “High school guidance counselors and teachers can use these findings to highlight the importance of doing well in high school for both short term (college admission) and longer term (earnings as an adult) goals.” Read more on education.
