Could Vigorous Exercise Help Those Predisposed to Gaining Weight?
Vigorous exercise may reduce the risk of obesity in people who have a genetic variant that predisposes them to being overweight, according to a new study. Researchers studied DNA samples from 704 healthy Amish adults with an average age 44. About 54 percent of male study participants and 64 percent of female participants were overweight, and 10 percent of men and 31 percent of women were obese. The study, published yesterday in Archives of Internal Medicine, found that those who possessed the genetic variant were no more likely to pack on the pounds than those who had a standard version of the gene, provided they got three to four hours of moderate physical activity—including activities like housecleaning, gardening, and brisk walking—per day, the Associated Press reports. The results suggest that people who have this genetic variant should pay particular attention to getting regular exercise, the researchers said.
Continuous Blood Glucose Monitoring May Benefit Type 1 Diabetics
Those with type 1 diabetes might benefit from a device worn under the skin that measures blood sugar around the clock, according to a new study. The device measures blood glucose levels every five minutes. The continuous glucose monitoring involves a disposable blood sugar sensor placed under the skin that is worn for a few days and then replaced. The sensor sends data to a transmitter, which then communicates the information to a receiver that a person can wear like a pager. The receiver displays continuous blood glucose levels. The study, published online yesterday in the New England Journal of Medicine, found that adults who used continuous glucose monitoring had substantially better control of their diabetes than a comparison group that used conventional, intermittent blood sugar management.
Woman, 59, Gives Birth to Healthy Triplets
A 59-year-old French woman delivered healthy triplets via C-section on Saturday, FoxNews.com reports. The woman traveled to a Vietnamese clinic willing to set aside the age limit of 45 imposed in France for in vitro fertilization. But by carrying multiple fetuses at such an advanced age, the woman certainly faced increased health risks, like diabetes and heart disease—to say nothing of the back and joint pain, Deborah Kotz reports. Childbirth among the 40-something set has tripled since the 1980s, according to a December report issued by the Public Policy Institute of California.
A study published in the July 15 issue of the Journal of the American College of Cardiology found that pregnancy boosts heart attack risk.
Declining Illegal Drug Use Among Teens
An increasing number of teenagers are choosing to steer clear of illegal drugs, with just 9.5 percent indulging in 2007, down from 11.6 percent in 2002, according to new federal statistics. The figures also say 18-to-25-year-olds increased their abuse of OxyContin and other prescription drugs. About 20 to 25 percent of teenagers are at serious risk of having drug and alcohol problems because of a combination of factors, including genetic susceptibility, social influences, and psychological issues, Nancy Shute reports.
