Obese women may be putting themselves at greater risk of breast cancer by not undergoing regular screening. According to new research by Dr. Nisa Maruthur and her team from The John Hopkins University School of Medicine in Baltimore, USA, seriously obese women are significantly less likely to say they have undergone a recent mammography than normal weight women, especially if they are white. Maruthur's findings are published online this week in Springer's Journal of General Internal Medicine.
The first U.S. charter school opened in 1992. Since then the number of charters has grown to more than 4,000 in 40 states, serving 1.2 million students, according to RAND, a nonprofit research organization based in Santa Monica, California.
Students at charter schools graduate and attend college at significantly higher rates than students at traditional public schools, according to a Rand Corp. study led by a Michigan State University scholar.The study, which offers mixed overall results for charter school advocates, comes amid a national debate over President Obama's endorsement of charter schools, which are experimental public schools that operate independently of the local school board.
