Home-based diet and exercise intervention can improve physical function in older cancer survivors

13.05.2009
A home-based program aimed at improving exercise and diet can lead to meaningful improvements in physical function among older long-term cancer survivors, according to the results of a study led by researchers from Duke University Medical Center and The University of Texas M. D. Anderson Cancer Center.

The findings were published in the May 13 issue of the Journal of the American Medical Association. The study was funded by the National Institutes of Health.

"We know that when people are diagnosed with cancer they're at risk for co-morbid conditions and functional decline, and those over 65 may become debilitated permanently, increasing health care costs and taking a toll on family members," said Wendy Demark-Wahnefried, M.D., Ph.D., a professor in M.D. Anderson's Department of Behavioral Science and senior investigator on this study.

Miriam Morey, Ph.D., a researcher in the Duke Center for Aging and at the Durham Veterans Affairs Medical Center, and lead investigator on the study, said "our study showed that by reaching out to older cancer survivors in their homes and giving them tools to improve diet and exercise, we were able to reduce the rate of functional decline in this population."

The research team identified 641 study participants who were considered overweight or obese - having a body mass index of 25 or greater - and who had been diagnosed with breast, colorectal or prostate cancer but had been treated and had not experienced a recurrence for five years or more. The participants also had no medical conditions that would have prohibited moderate exercise.

A control group of 322 participants were told to go about their normal routines with no intervention, with the promise that they would receive access to the program one year later, Demark-Wahnefried said. The remaining 319 received 15 telephone counseling sessions with a personal trainer throughout the intervention year, and worked toward establishing several daily goals, including performing lower body strength exercises; walking 30 minutes; using portion-control plates, cups and bowls; consuming fewer than 10 percent of calories from saturated fat; and eating more fruits and vegetables.

Participants also received a personally-tailored workbook and a series of quarterly newsletters designed to help them maintain their exercise and diet routines.

"We found that the intervention group had higher levels of physical function, such as going up and down stairs, stepping on and off a stool, or running a short distance," said Morey.

The researchers used scoring systems to assess function that assign points based on participants' ability to perform such physical tasks, Morey said. Participants receive a score that ranges from zero to 100, with higher scores indicating better function.

Participants in the control arm had decreases in physical function of almost five points over the one-year study period, while those in the intervention group had declines that were only slightly over two points to a level that was not even clinically detectable, Morey said.

"In 2008, the Centers for Medicare and Medicaid Services declared that research aimed at maintaining mobility and function in at-risk elders as the only aging priority," said Morey. "The wonderful thing about this intervention is that it would be accessible to anyone with a phone in an English-speaking country; our study participants were in Canada, the UK and in 21 of the United States. Participants did not have to join a gym or go anywhere; they received the intervention right where they live."

Co-authors with Morey and Demark-Wahnefried are; Denise Snyder, M.S., R.D., Richard Sloane, M.S., M.P.H., Harvey Jay Cohen, M.D., and Bercedis Peterson, Ph.D., of Duke; and Terryl Hartman, Ph.D., M.P.H., Paige Miller, M.S., and Diane Mitchell, M.S., R.D., of Pennsylvania State University.

About M. D. Anderson

The University of Texas M. D. Anderson Cancer Center in Houston ranks as one of the world's most respected centers focused on cancer patient care, research, education and prevention. M. D. Anderson is one of only 40 comprehensive cancer centers designated by the National Cancer Institute. For four of the past six years, including 2008, M. D. Anderson has ranked No. 1 in cancer care in "America's Best Hospitals," a survey published annually in U.S. News & World Report.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
