‘Epidemic’ of Inactivity Tied to Poor Health, Rising Costs

Two prominent researchers have sounded the alarm again about Americans’ unhealthy, even lethal, sedentary lifestyles.

A new commentary, “Regular Physical Activity: Forgotten Benefits,” published online ahead of print in the American Journal of Medicine, laments the lack of physical activity by Americans. In the paper, Florida Atlantic University’s Steven Lewis, Ph.D., and Charles H. Hennekens, M.D., Dr. P.H., stress how lack of physical activity in Americans poses important clinical, public health, and fiscal challenges for the nation.

“Lack of physical activity accounts for 22 percent of coronary heart disease, 22 percent of colon cancer, 18 percent of osteoporotic fractures, 12 percent of diabetes and hypertension, and five percent of breast cancer,” said Hennekens.

“Furthermore, physical inactivity accounts for about 2.4 percent of U.S. health care expenditures or approximately $24 billion a year.”

The statistics of physical inactivity in the U.S. are staggering. According to Healthy People 2020, approximately 36 percent of adults do not engage in any leisure-time physical activity, despite the fact that walking may be comparable to more vigorous exercise in preventing a cardiovascular event.

Even in patients who have had a heart attack and who undergo cardiac rehabilitation, it’s estimated that less than 15 percent actually participate in cardiac rehabilitation following discharge.

Men and women who engage in regular physical activity experience statistically significant and clinically important reductions in the risk of dying from coronary heart disease, the leading cause of death in the U.S.

The authors point out that brisk walking every day for only 20 minutes, which can be practiced even among the oldest adults, confers a 30 to 40 percent reduced risk of a heart attack.

The benefits of physical activity also include improved mental health and stronger muscles, bones, and joints in all Americans from childhood to the elderly.

“There’s a lot more that we can do to address this national epidemic among people of all ages,” said Lewis.

“For example, clinicians should screen and refer obese patients to programs that offer intensive counseling for weight control and physical activity. This simple, straightforward and easily achievable objective may be the first necessary step to lower rates of obesity and physical inactivity in the U.S. today.”

Patients commonly ask their physicians questions such as, “What exercise should I do?” “How long should I do the exercise, how often and how hard do I need to exercise?”

These questions need to be answered better, say the authors. They emphasize the need for better defined guidelines for the types, intensities, frequencies, and durations of exercise for clinicians to provide to their patients.

“Unfortunately, most Americans prefer prescription of pills to proscription of harmful lifestyles such as physical inactivity,” said Hennekens.

“In general, any pharmacologic intervention should be an adjunct, not alternative, to therapeutic lifestyle changes such as increasing levels of physical activity. Based on the current totality of evidence, when compared with most pharmacologic therapies, exercise is more readily available at a low cost and relatively free of adverse effect.”
