Public Health News Roundup: May 3
A new survey by the MetLife Foundation and the Partnership at DrugFree.org finds that marijuana use is becoming a more acceptable behavior among teens and heavy marijuana use is now at very high levels.
Nearly half of teens (47 percent) have ever used marijuana – a 21 percent increase since 2008, and two out of every five teens (39 percent) have tried marijuana in the past year, up from 31 percent in 2008. Past-month use has increased 42 percent from 19 percent in 2008 to 27 percent in 2011. Heavy monthly use (20 or more times) rose from 5 percent in 2008 to 9 percent in 2011. The survey also found that teen boys are more frequent users of marijuana than teen girls.
Postmenopausal women who were overweight or obese and lost at least 5 percent of their body weight had a significant reduction in markers of inflammation, according to a study published in Cancer Research.
The study authors say both obesity and inflammation have been shown to be related to several types of cancer, and that the study shows that if you reduce weight, you can reduce inflammation as well.
A salmonella outbreak linked to a frozen yellow fin tuna product has now sickened 258 people in 24 states and the District of Columbia, according to an update released by the Centers for Disease Control and Prevention on Wednesday. At least 32 people have been hospitalized but no deaths have been reported.
The CDC says it is now including two types of salmonella in the outbreak strains--Salmonella Bareilly (247 cases) and Salmonella Nchanga (11 cases).
On April 16, nearly 59,000 pounds of tuna product linked to the outbreak -- labeled Nakaochi Scrape AA or AAA -- were recalled by Moon Marine USA Corp. of Cupertino, Calif. The product, which is scraped off fish bones, was sold to grocery stores and restaurants to make dishes such as sushi, sashimi and ceviche.
