Transit Users More Likely to Meet Exercise Guidelines: Study

Transit users are three times more likely to achieve fitness guidelines than those who don't use transit, say Canadian researchers who interviewed 18,326 people in Atlanta, Ga., who kept diaries of their modes of travel over two consecutive days.

The study used the Heart and Stroke Foundation of Canada's suggested daily minimum of 30 minutes of moderate physical activity a day, five days a week, CBC News reported.

WHAT TO KNOW
    • Transit Users More Likely to Meet Exercise Guidelines: Study
    • VA Says 10 Patients Test Positive for Hepatitis
    • China Reports More Cases of Hand, Foot and Mouth Disease
    • Hot Tea May Increase Throat Cancer Risk: Study

The more people in the study used their cars, they less likely they were to meet the minimum activity guideline, said the University of British Columbia study.

"The idea of needing to go to the gym to get your daily dose of exercise is a misperception," associate professor Lawrence Frank, who teaches community and regional planning, said in a news release, CBC News reported.

"These short walks throughout our day are historically how we have gotten our activity," he noted. "Unfortunately, we've engineered this activity out of our daily lives."

The study was published in the Journal of Public Health Policy.

VA Says 10 Patients Test Positive for Hepatitis

Ten people have tested positive for hepatitis after they were exposed to contaminated colonoscopy equipment, the U.S. Veterans Affairs department said Friday.

The 10 are among thousands of patients told to get blood tests after having colonoscopies at VA facilities in Murfreesboro, Tenn., Miami and Augusta, Ga. The equipment at those facilities wasn't properly sterilized between procedures, the Associated Press reported.

Four patients have tested positive for hepatitis B, and six have tested positive for hepatitis C, which can cause permanent liver damage and is potentially life-threatening.

The patients will receive treatment from the VA even though it hasn't been confirmed that their infections were the result of the unclean colonoscopy equipment, said VA spokeswoman Katie Roberts, the AP reported.

China Reports More Cases of Hand, Foot and Mouth Disease

So far this year, 41,000 people in China have been sickened by hand, foot and mouth disease, and 18 children have died, Chinese health officials said Friday.

Based on previously release data, about twice as many people have been infected so far this year compared with the same time period last year, the Associated Press reported.

May through July is the normal peak season for the spread of the disease, so this early spike suggests this year's toll will be higher than average, said Li Xinwang, a doctor at Beijing's Ditan Hospital.

He suggested the high number of cases so far this year may be due to "dramatic temperature fluctuations" which helped spread the virus, especially in rural areas where sanitation and health care are substandard, the AP reported.

Hand, foot and mouth disease typically strikes infants and children. It can be deadly, but most cases are mild, and children recover quickly after suffering little more than a fever and rash.
