Maybe TV doesn't always perpetuate the couch potato set after all. A new study by researchers at the University of Southern California suggests that some TV may be good for you.

Researchers found that a storyline on the primetime NBC network drama ER that dealt with teen obesity, hypertension and healthy eating habits had a positive impact on the attitudes and behaviors of viewers, particularly among men.

The study, published in the Sept. 14 Journal of Health Communication, offered researchers a rare opportunity to evaluate the impact of health messages in entertainment, says Thomas W. Valente, Ph.D., associate professor of preventive medicine and member of the Institute for Health Promotion & Disease Prevention Research (IPR) at the Keck School of Medicine of USC.

“This study demonstrates the importance of interventions and programs targeted at a population level,” Valente said. “We have so many public heath issues to deal with, we can’t restrict ourselves to any one strategy. We have to do everything and anything we can to help people improve their health.”

The storyline depicted an African-American teen who is diagnosed with hypertension during a visit to the emergency room and is advised to eat more fruits and vegetables and to get more exercise. The story aired over three episodes from April 29 to May 13, 2004.

The impact of the episodes was evaluated using three separate datasets, one of which provided data on a sample of 807 primetime viewers before and after the episodes aired. An independent firm collected surveys from viewers, measuring whether their self-reported behavior and their nutrition attitudes, knowledge and practices were impacted by the storyline.

Results showed that ER viewers were 65 percent more likely to report a positive change in their behavior after watching the episodes. The results also suggested that the storyline had modest impacts on knowledge, attitudes and practices, Valente notes.

Those who watched ER also had a five percent higher rate of knowledge about nutrition than those who did not. Researchers accounted for a number of factors, including age, sex, ethnicity, income and education.

Interestingly, the effects were stronger for men than they were for women. Researchers theorize this may be because men started with a lower baseline knowledge of the information shown in the episodes, Valente said.

While the overall impact may be relatively small, the study highlights the potential of entertainment television as a medium for health communication, Valente said. It can be particularly helpful since people who are heavy TV watchers are more likely to be at risk for obesity, he notes.

“People get their information from entertainment,” Valente says. “It’s not a magic bullet. It’s a small piece of the puzzle, but we’d be silly to ignore its potential.”
