Healthy physicians make better role models, research shows

A physician’s health influences how comfortable he or she is offering healthy advice to patients — and that could motivate patients to adopt positive lifestyle changes, according to new research.

“Practicing what we preach is important,” said Jo Marie Reilly, MD, a family physician and associate professor at the Keck School of Medicine at the University of Southern California. “Physicians are just more aware and better able to counsel patients if they take care of themselves.”

A survey of 1,000 primary care physicians found that those who exercised at least once a week or didn’t smoke were about twice as likely to recommend five lifestyle changes to patients with hypertension. Those changes: eat a healthy diet, reduce salt intake, attain or maintain a healthy weight, limit alcohol use and exercise regularly.

The survey, presented March 14 at an American Heart Assn. meeting, found that 4% of the doctors smoked at least once a week, 27% exercised at least five days a week and 39% ate the recommended five cups of fruits and vegetables a week.

Doctors who lead healthy lifestyles demonstrate that they believe in the importance of preventive health, said Ralph Sacco, MD, AHA immediate past president and chairman of neurology at the University of Miami Miller School of Medicine.

“Physicians who are healthier themselves are more apt to counsel patients about healthy lifestyle and diet,” he said. “They are more educated, more personally invested in personal health and therefore, better health advocates for their patients.”

The research follows a study in the Jan. 19 issue of Obesity that looked at how a physician’s body mass index influences whether doctors talk with overweight patients about losing weight. In the survey of 498 physicians, researchers found that 30% of doctors with a healthy BMI spoke with patients about losing weight, compared with 18% of overweight or obese physicians.

A study in the fall 2010 issue of Preventive Cardiology showed that doctors who exercised regularly and maintained a healthy weight were most comfortable talking with patients about making healthy lifestyle choices.

Helping to fight obesity

More than one-third of U.S. adults and about 17% of children and adolescents are obese, defined as having a body mass index of 30 or higher, says the Centers for Disease Control and Prevention. Those high obesity rates contribute to more cases of chronic conditions such as diabetes, heart disease and hypertension.

Physicians will play an increasingly key role in combating chronic conditions as the health care system focuses more on prevention in coming years, said Dept. of Health and Human Services Secretary Kathleen Sebelius. She made the remark in a March 9 speech at the American Medical Students Assn.’s Annual Convention in Houston.

“There is a growing body of evidence that people’s behaviors outside the health care system — what we eat, how much we exercise, whether we smoke or not — affect our health just as much, if not more, than the treatments and medicines we get when we visit a doctor,” she said.

Even if physicians aren’t physically fit themselves, they can help patients by talking about their personal struggles with weight or other health issues, said Dr. Reilly, who has written about how physician health influences patients.

Doctors can encourage others in their office to adopt healthy behaviors and avoid negative influences such as having snack machines full of junk food in the break room. Most important, physicians need to make sure they take time to talk with patients about making healthy choices, she said.

“It’s really important that we take that time to counsel patients about how their health habits influence their lives at each visit, and that we look at that as important as any medication,” Dr. Reilly said.
