Regulations to Limit Youth Smoking also Lower Adult Rates
Regulation to limit youth smoking may also decrease the rate of adult smoking, according to a new study in the American Journal of Health. The study found that states with stricter regulations targeted youth tobacco use also saw lower incidence of adult use, especially among women. "In most states for many years, it has been illegal to sell cigarettes to people under 18, but few provisions are in place to prevent those sales," said study author Richard Grucza, an associate professor of psychiatry at Washington University School of Medicine in St. Louis. "This study shows that more restrictive policies can prevent teen smoking and be beneficial down the road." The most effective policies included eliminating cigarette vending machines, ID requirements to purchase cigarettes and restrictions preventing smaller packages of cigarettes. Gurzca estimated that if all states had such effective policies then smoking would be cut about 14 percent and heavy smoking would drop 29 percent. Read more on tobacco.

‘Watchful Waiting’ Approach to Prostate Cancer Can Reduce Unneeded Treatment
A “wait and see” approach to slow-growing prostate cancer—also known as “watchful waiting”—could reduce the number of unnecessary treatments, according to a new study in the Annals of Internal Medicine. The study took into account costs, side effects, quality of life and the chance of dying. "Most of the men who are diagnosed in this country these days have low-risk prostate cancer," said Julia Hayes, MD, who led the new study at the Dana-Farber Cancer Institute Boston. "There's a huge group of men out there who are probably treated unnecessarily." The slow-growing cancer “may never grow large or fast enough to threaten a man's life,” according to Reuters. Researchers estimate that men under the “watchful waiting” approach would ultimately undergo treatment in 34 percent of cases; active surveillance would lead to 78 percent. Read more on cancer.

Younger Americans Less Likely to Be Aware of their HIV, Undergo Treatment
People under age 45 who are infected with HIV are far less likely that their older counterparts to know about the infection and to be receiving treatment, according to a new study in the journal JAMA Internal Medicine. About 40 percent of people between ages 13-24 had been diagnosed and only 30 were referred for care. Those ages 25-44 also saw lower rates than people 45 and older. A total of more than 850,000 Americans with HIV have not achieved suppression. The researchers, led by H. Irene Hall of the U.S. Centers for Disease Control and Prevention, concluded that "Individuals, health care providers, health departments and government agencies must all work together to increase the numbers of people living with HIV who are aware of their status, linked to and retained in care, receiving treatment and adherent to treatment."
