Kids' screen time is linked to development of hypertension
More time plopped in front of a screen - computer, video, video game, and, particularly, television - may raise the risk of elevated blood pressure in children, according to a new study.
The researchers tracked activity levels of 111 children ages 3 to 8 - 57 boys and 54 girls - round-the-clock for a week via measurements from an accelerometer worn over the right hip as well as parents' reports of the average time their child spent sitting or engaging in activities that ranged from painting to watching TV. They also considered age, sex, height, percentage of body fat, and other differences.
Excessive TV time and total screen time were linked to elevated blood pressure - a risk factor for cardiovascular disease and other health problems - even when possibly related measures, such as body fat, were separated from the analysis. Children who spent less than 30 minutes a day in front of a screen tended to have the lowest blood pressures, the researchers report in the August issue of Archives of Pediatrics and Adolescent Medicine. (The average was 90 minutes.)
Interestingly, the researchers did not find an association between blood pressure and sedentary behavior in general, leading them to suggest that factors specific to watching a screen - eating foods high in sugar, fat and salt, for example, or disruptive sleep patterns that have been associated with TV time - might play a role. - Heather J.

Personal Health: On Statins and Walking Aids
Published on Monday, July 6, 2009 in THE PHILADELPHIA INQUIRER.
Likely benefits to prescribing statins to curb heart disease
Cholesterol-lowering statin drugs, the standard of care for people with heart disease, may also benefit many patients who are merely at risk of developing the disease, researchers report in a review of 10 previous studies involving 70,000 people worldwide.
Prescribing statins as a preventive measure to patients with risk factors such as diabetes and high blood pressure was associated with a 30 percent drop in major heart disease and a 12 percent drop in deaths over an average of four years, researchers said on bmj.com, an online British medical journal.
Statins are powerful drugs, and the researchers - several of whom reported support in the past from manufacturers - stopped short of recommending their use for all people at risk of developing heart disease.
While men over 65 who have other risk factors and older women with diabetes and other risk factors appear to be most in danger of developing heart disease, they write, "the correct identification of such people remains a challenge," as does prediction of an individual's risk. - Heather J. Chin
Study of falls suggests need to teach safer use of walkers
More than 47,000 older Americans a year - 129 a day - seek treatment at hospitals after falls involving walkers or canes, according to a six-year review of ER records that suggests more time should be spent teaching people how to use walking aids.
Falls are the leading cause of injuries in people over 65. Less than 3 percent involve walking aids, but the researchers, from the U.S. Centers for Disease Control and Prevention, said they were the frailest and most vulnerable population. And while twice as many older people use canes than use walkers, the researchers found seven times as many injuries associated with walkers.
Fractures were the most common type of injury. Men injured their head and neck most frequently, while women hit their hip or pelvis. Women, who are more likely to use walkers, made up 77 percent of all falls examined.
The goal now, the authors write in the Journal of the American Geriatrics Society, is to identify potential risk factors that lead to falls, to design better walking aids, and to provide education on safe usage.
