In 2010, when Susan Rossman was offered the opportunity to participate in a University of Alabama at Birmingham (UAB) pilot study of a vegetable gardening intervention that paired her with a local master gardener mentor from the Alabama Cooperative Extension Service and provided her with the necessary gardening supplies, she jumped at the chance.
Since 1981, Alabama Master Gardeners have been important volunteers with the Alabama Cooperative Extension System (ACES), hosting displays and information booths at county fairs, offering educational programs, assisting at botanical gardens, working with historic properties, implementing civic beautification projects, partnering with local schools, donating fresh produce to charity, supporting scholarships in secondary education, and much more.

As Rossman predicted, the intervention produced significant improvements in several aspects of physical health among participants, which included four breast, four prostate, and four childhood cancer survivors (and their parents). Specifically, results indicated:
Better hand grip strength (+4.5 [3.0 to 6.7] kg)
Improved agility as assessed by the 8 foot Up and Go (−1.5 [−2.1 to −0.2] seconds)
Improved leg strength as assessed by the 30-second chair stand (+1.5 [−1.0 to 5.0] stands)
Improved endurance as assessed by the 6-minute walk (+38 [20 to 120] feet).
Half of the cancer survivors also increased their vegetable and fruit intake by at least one serving per day and two-thirds increased their physical activity by at least 30 minutes per week.1 Results from this pilot study, led to two larger feasibility studies that assessed the effects of the vegetable gardening intervention among a total of 128 additional cancer survivors. Findings from these two trials reinforced the positive changes observed in the first study,2,3 and led to a large, National Cancer Institute (NCI)-funded (NCT02985411) randomized controlled trial. The trial, called Harvest for Health, will accrue a variety of cancer survivors across Alabama and will complete enrollment in April 2020 in the northern part of the state (Harvest4Health@uab.edu),
Harvest for Health
The trial is a community-based partnership between UAB and Auburn University that began in 2010, when Wendy Demark-Wahnefried, PhD, RD, a cancer survivorship researcher, was recruited to UAB and reached-out to Tony Glover, an ACES coordinator. Dr. Demark-Wahnefried had previous experience with the Master Gardener program when she was on faculty at Duke University and wondered if the Alabama Cooperative Extension would be interested in collaborating on a pilot study that would be supported through some of her start-up funds. The small pilot study eventually led to the large randomized controlled trial currently in the field. Harvest for Health is testing the effects of vegetable gardening in more than 300 cancer survivors ages 60 and older—an age group that is particularly vulnerable to declines in physical functioning. The study aims to improve vegetable intake, physical activity and function, health-related quality of life (QOL), and select biomarkers of healthy aging (e.g., interleukin-6 [IL6] and telomerase). Harvest for Health participants are randomly assigned to either the one-year mentored, home-based vegetable gardening intervention immediately or to another group that will receive the intervention after a one-year waiting period. Participants are paired with master gardeners who provide guidance in planning, planting, and maintaining a spring, summer, and fall garden. Vegetables grown in these gardens include: lettuce, peppers, squash, and tomatoes, as well as any other vegetable the survivor wants.
Every six months, participants complete surveys on their diet, physical activity, and QOL either by mail or online. In-person assessments are conducted at baseline, one-year, and two-years at the participants’ home or community centers and consist of measuring weight, height and waist circumference, testing physical performance, and collecting biospecimens (i.e., saliva and toenail clippings to measure cortisol [stress hormone], fecal samples to assess potential changes in the microbiome, and blood to quantify changes in IL6 and telomerase).
While the study is still ongoing, feedback from participants is positive. Sarah Harkless, a former schoolteacher and current research participant has enjoyed playing an active role in her health by gardening and receiving all the necessary tools and support needed to grow a successful garden. She feels that Harvest for Health has given her a “jump start” on healthier living. “I am eating new things and I am now back in the kitchen cooking. Gardening makes me want to do better. I am eating better and have even lost 10 pounds. It has given me something to look forward to every day. I love it, my family loves it!”
Patricia Saffles, Harkless’s master gardener mentor who recently lost her husband to cancer, signed-up to volunteer for Harvest for Health to “give back and make a difference in someone’s life.” Saffles has always had a passion for growing flowers and was so inspired by Harkless and her veggies that she has started a vegetable garden of her own. Her new passion for growing vegetables has led her to make heathier eating choices. Saffles believes that Harvest for Health is mutually beneficial for cancer survivors and master gardeners, “We have had a great time, a lot of laughs, and are learning from each other. Sarah even inspires me to try new things in my garden.”
Harvest for Health offers a holistic means to improve both diet and exercise behaviors to improve the overall health of cancer survivors. But, not all cancer survivors are interested in sowing seeds in order to “shovel-up” better health.4 Thus, the research team which was originally based just at UAB has expanded to the University of Tennessee Health Science Center (with the subsequent moves of some members) and are exploring other ways to improve dietary and physical activity behaviors, as well as promote safe weight loss among cancer survivors who struggle with making changes in their diet, exercising, and managing their weight, particularly if they carried a few extra pounds before their diagnosis and gained even more weight with treatment—as many cancer survivors do.
Web-Based Clinical Trials
The UAB/University of Tennessee Health Science Center team is now recruiting cancer survivors across the southeastern U.S. (Alabama, Mississippi, North Carolina, and Tennessee) for two new web-based healthy lifestyle trials. See Table 1, page XX, for eligibility criteria, contact information, and other study details.

The Aim, Plan, and Act on Lifestyles (AMPLIFY) Survivor Health (NCT04000880) is NCI-funded and builds on two previous NCI-funded research clinical trials that tested diet and exercise interventions that were found to be effective.
The Better Exercise Adherence after Treatment for Cancer (BEAT Cancer) research clinical trial (NCT00929617) tested an in-person exercise intervention that gradually tapered to a home-based program among 222 breast cancer survivors. The BEAT Cancer intervention significantly improved levels of physical activity, as well as fitness and quality of life—effects which were maintained at a 6-month follow-up.5
Likewise, the Reach-out to Enhance Wellness (RENEW) in Older Cancer Survivors research clinical trial (NCT00303875) tested the efficacy of a one-year program of tailored mailed print materials plus telephone counseling among 641 older, overweight and obese survivors of breast, prostate, and colorectal cancer who resided in 21 U.S. States, as well as Canada and the United Kingdom. The RENEW intervention significantly improved diet quality, physical activity, and body weight status—effects that were durable at a two-year follow-up.6,7 Most importantly, the intervention reduced the rate of physical function decline among these cancer survivors.
In the words of participant, Paul Finegan, “RENEW was, and is so very good for me! The in-home program provided helpful information and was very convenient. I lost 15 pounds and kept it off. Ten years later, I still watch my portions and eat very little red meat. As a former teacher, I give the program an A+.” Like other RENEW participants, Finegan’s physical function improved on the program. Now, at age 87, Finegan says, “I have no trouble walking a mile or climbing 10 flights of stairs. In fact, I am busy building houses for Habitat for Humanity several days a week.”
Over the past year, the AMPLIFY study team has worked to adapt both BEAT Cancer and RENEW to a web-based platform that can be delivered via computers, tablets, and smartphones to enhance dissemination potential. In addition, AMPLIFY provides diet and exercise guidance according to the most recent recommendations issued by the American Institute of Cancer Research and the National Comprehensive Cancer Network (NCCN).8,9 The goals of AMPLIFY are to test the impact of the diet and exercise interventions on change in health behaviors, physical performance, body weight, muscle mass, and overall health and QOL. Plus, AMPLIFY will determine whether the diet and exercise components are more effective if delivered one at a time (first diet then exercise, or vice versa) or combined over a 12-month period. The enrollment target is 652 cancer survivors across the states of Alabama, Mississippi, North Carolina, and Tennessee and kicked-off in January 2020 to coincide with the new year—a perfect time to begin healthful resolutions.
The Daughters, Dudes, Mothers, and Others Together (DUET) research clinical trial is funded by the American Institute of Cancer Research and is similar to the AMPLIFY clinical research trial, the primary difference between the two is that the DUET research clinical trial will intervene upon the lifestyle behaviors of cancer survivors and their chosen partners. Fifty-six cancer survivors will enroll in this six-month diet and exercise weight management program with a partner of their choosing, e.g., a friend, neighbor, spouse, or other relative. This trial banks on a previous research clinical trial, Daughters and Mothers (DAMES) Against Breast Cancer (NCT00630591) which was limited to mothers with breast cancer and their biological daughters. Significant weight loss and changes in diet and exercise were noted with this trial of 68 mother-daughter dyads.10 In fact, success in one DAMES family was particularly remarkable. Over the course of the one-year study, the breast cancer survivor lost 23 pounds and her daughter lost ten, but pound for pound, the biggest loser was the family dog (“Rocky”) who lost 11 pounds as he served as the walking companion for the two DAMES participants. By expanding the number of eligible cancer types for survivors, and the relationships between survivors and their chosen partners in the current study, Demark-Wahnefried and her research team hope to improve the generalizability and the reach of this partner-based intervention.
The UAB/University of Tennessee Health Science Center team is eager to take cancer survivorship research to the next level by extending the reach of evidence-based interventions and programs designed to promote the health and well-being of cancer survivors. Research interventions like Harvest for Health, AMPLIFY, and DUET offer potential cost-effective, viable solutions for community cancer programs to help their patients achieve optimal health outcomes. These research programs—at no cost to community cancer programs—provide a much-needed resource for survivors and addresses patient goals to live a full and healthy life. Research programs are value-added to patient care. Cancer centers who are interested in learning more about the programs are encouraged to refer cancer survivors to either the AMPLIFY or DUET programs - see Table 1,
In closing and in the words of Harvest for Health participant, Susan Rossman: “Cancer can be the worst thing that can happen to you, or it can be a life changing event that you do something with. If every cancer survivor could do something like this, it could change the way they look at everything.”




I believe that people who actively participate in their own health do much better. After all, exercise is so connected to mental health, and paying attention to what you feed your body makes a big difference in overall health—it just makes sense.
