Regular physical activity reduces the progression of several cancers and offers physical and mental health benefits for cancer survivors. However, many cancer survivors are not sufficiently active to achieve these health benefits. Possible biological mechanisms through which physical activity could affect cancer progression include reduced systemic inflammation and positive changes in metabolic markers. Chronic and acute hyperglycemia could have downstream effects on cell proliferation and tumorigenesis. One novel strategy to motivate cancer survivors to be more active is to provide personalized biological-based feedback that demonstrates the immediate positive impact of physical activity. Continuous glucose monitors (CGMs) have been used to demonstrate the acute beneficial effects of physical activity on insulin sensitivity and glucose metabolisms in controlled lab settings. Using personal data from CGMs to illustrate the immediate impact of physical activity on glucose patterns could be particularly relevant for cancer survivors because they are at a higher risk for developing type 2 diabetes (T2D). As a pilot project, this study aims to (1) test the preliminary effect of a remotely delivered physical activity intervention that incorporates personalized biological-based feedback on daily physical activity levels, and (2) explore the association between daily glucose patterns and cancer-related insulin pathway and inflammatory biomarkers in cancer survivors who are at high risk for T2D. We will recruit 50 insufficiently active, post-treatment cancer survivors who are at elevated risk for T2D. Participants will be randomly assigned into (1) a group that receives personalized biological feedback related to physical activity behaviors; and (2) a control group that receives standard educational material. The feasibility and preliminary efficacy of this wearable sensor-based, biofeedback-enhanced 12-week physical activity intervention will be evaluated. Data from this study will support the further refinement and enhancement of a more comprehensive remotely delivered physical activity intervention that targets cancer survivors.

Background Food insecurity, an economic and social condition of limited food access, is associated with poor diet quality—a risk factor for several common cancers. The University of Texas MD Anderson Cancer Center supports healthy food access through community‐led evidence translation by actively partnering with community‐based organizations (CBOs). These partnerships aim to enhance the capacity of food assistance CBOs to effectively implement evidence‐based food insecurity mitigation programs in the cancer center's area of influence. Methods This case study aims to describe the cancer center's model for local food access capacity building and detail operationalization in the context of a whole‐community cancer prevention effort (Be Well Baytown) in Baytown, Texas. Results Elements central to the capacity building model include (i) assessment of baseline needs and capacity, (ii) empowering a community champion within a relevant CBO, (iii) mapping inter‐sectoral community partnerships, collaborations, and linkages, and (iv) leveraging systems, connections, and resources to provide an enabling environment for overall food access systems growth. Through this process, Be Well Baytown enhanced the capacity of a local food pantry leading to increases in total reach, pounds of food distributed, and number of food distribution events in collaboration with intersectoral partners from 2018 to 2023. Conclusion This case study highlights the model's implementation as a co‐benefit community partnership strategy to maximize the impact of food security programs integrated with comprehensive cancer center prevention efforts. The purpose of this case study is to summarize learning from supporting food assistance CBOs to effectively implement evidence‐based food insecurity mitigation programs and to better understand how to optimize use of community‐driven food security programs aligned to Comprehensive Cancer Center's (CCC) community outreach and engagement (COE) efforts. The case study demonstrates a successful community partnership strategy integrating food security programs into comprehensive cancer prevention efforts that improved the capacity of a local food pantry, resulted in expanded reach, increased food distribution, and more collaborations with partners from 2018 to 2023 offering a model for other CCCs.

Objective The COVID‐19 pandemic has been shown to be negatively associated with physical activity engagement, adherence to healthy diet, and weight management among people with obesity. The current study examined COVID‐19‐related changes in weight, physical activity (PA), and diet among employees with obesity or overweight who participated in Vibrant Lives (VL), a worksite weight loss program. Methods School district employees participated in the 6‐month VL weight loss program and were categorized into non‐COVID‐era participants and COVID‐era participants. Participants completed questionnaires about PA and dietary intake at baseline and follow‐up. COVID‐era participants reported the effects of pandemic on their behaviors. Changes in weight, PA, and diet were compared between groups using multilevel linear mixed models and logistic regression models. Results A total of 266 participants (non‐COVID, n = 173; COVID, n = 93) were included. Significant weight loss (non‐COVID, −2.3 kg vs. COVID, −1.3 kg) and increases in moderate‐to‐vigorous PA minutes (non‐COVID, 48.7 min vs. COVID, 61.5 min) were observed associated with the program, but no significant differences in changes between the groups were found. Compared to non‐COVID participants, COVID participants decreased fast food consumption (p = 0.008) and increased sugar‐sweetened beverage intake (p = 0.016). Higher frequency of snacking and overeating were reported as barriers to a healthy diet. Conclusion The COVID‐19 pandemic was negatively associated with healthful dietary behaviors. The information obtained from participants regarding the reasons for their pandemic‐related changes in diet may help identify strategies to encourage healthier behaviors and weight management among people who have been negatively affected by the COVID‐19 pandemic.

Purpose: To investigate relationships among physical activity, changes in physical function, and health-related quality of life (HRQOL) among patients with pancreatic adenocarcinoma enrolled in a home-based exercise prehabilitation program. Methods: Patients with resectable pancreatic adenocarcinoma receiving preoperative chemotherapy and/or chemoradiation were enrolled on this prospective, single-arm trial and were advised to perform ≥60 minutes each of moderate-intensity aerobic exercise and strengthening exercise weekly. Activity was measured via self-report and accelerometers, including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary activity (SA). Physical function measures at baseline and restaging follow-up included 6-minute walk test (6MWT), 5 times sit-to-stand (5×STS), handgrip strength (HGS), 3-m walk for gait speed (GS), and the PROMIS Physical Function Short Form. HRQOL was measured via the FACT-Hep questionnaire. Results: Fifty participants with mean age 66 years (standard deviation = 8 years) were enrolled. The 6MWT, 5×STS, and GS significantly improved from baseline to restaging follow-up (P=.001, P=.049, and P=.009, respectively). Increases in self-reported aerobic exercise, weekly MVPA, and LPA were associated with improvement in 6MWT (β=.19, P=.048; β=.18, P=.03; and β=.08, P=.03, respectively) and self-reported physical functioning (β=.02, P=.03; β=.03, P=.005; and β=.01, P=.02, respectively). Increased weekly LPA was associated with increased HRQOL (β=.03, P=.02). Increased SA was associated with decreased HRQOL (β=-.02,P=.01). Conclusions: Patients with potentially resectable pancreatic cancer exhibit meaningful improvement in physical function with prehabilitation; physical activity was associated with improved physical function and HRQOL. These data highlight the importance of physical activity during treatment for pancreatic cancer.

Background Older adult women often do not engage in sufficient physical activity (PA) and can encounter biological changes that exacerbate the negative effects of inadequate activity. Wearable activity monitors can facilitate PA initiation, but evidence of sustained behavior change is lacking. Supplementing wearable technologies with intervention content that evokes enjoyment, interest, meaning, and personal values associated with PA may support long term adherence. In this paper, we present the protocol of an NIA-funded study designed to evaluate the efficacy of CHALLENGE for increasing step count and motivation for PA in insufficiently active older women (Challenges for Healthy Aging: Leveraging Limits for Engaging Networked Game-based Exercise). CHALLENGE uses social media to supplement wearable activity monitors with the autonomy-supportive frame of a game. We hypothesize that CHALLENGE will engender playful experiences that will improve motivation for exercise and lead to sustained increases in step count. Methods We will recruit 300 healthy, community dwelling older adult women on a rolling basis and randomize them to receive either the CHALLENGE intervention (experimental arm) or an activity monitor-only intervention (comparison arm). Participants in both groups will receive a wearable activity monitor and personalized weekly feedback emails. In the experimental group, participants will also be added to a private Facebook group, where study staff will post weekly challenges that are designed to elicit playful experiences while walking. Assessments at baseline and 6, 12, and 18 months will measure PA and motivation-related constructs. We will fit linear mixed-effects models to evaluate differences in step count and motivational constructs, and longitudinal mediation models to evaluate if interventional effects are mediated by changes in motivation. We will also conduct thematic content analysis of text and photos posted to Facebook and transcripts from individual interviews. Discussion By taking part in a year-long intervention centered on imbuing walking behaviors with playful and celebratory experiences, participating older adult women may internalize changes to their identity and relationship with PA that facilitate sustained behavior change. Study results will have implications for how we can harness powerful and increasingly ubiquitous technologies for health promotion to the vast and growing population of older adults in the U.S. and abroad.

The effects of Vibrant Lives, a 6-month worksite-weight-loss program, were examined in a cohort of school-district employees with overweight or obesity. The VL Basic (VLB) participants received materials and tailored text messages, the VL Plus (VLP) participants additionally received WIFI-enabled activity monitors and scales and participated in health challenges throughout the school year, and the VL Plus with Support (VLP + S) participants additionally received coaching support. The levels of program satisfaction and retention and changes in weight, physical activity (PA), and diet were compared across groups using Pearson chi-square tests, repeated-measure mixed models, and logistic regression. After the program, the VLB (n = 131), VLP (n = 87), and VLP + S (n = 88) groups had average weight losses of 2.5, 2.5, and 3.4 kg, respectively, and average increases in weekly PA of 40.4, 35.8, and 65.7 min, respectively. The VLP + S participants were more likely than the other participants to have clinically significant weight loss (≥3%; p = 0.026). Compared with the VLB participants, the VLP participants were less likely to meet the recommendations for consuming fast food (p = 0.022) and sugar-sweetened beverages (p = 0.010). The VLP and VLP + S participants reported higher program satisfaction than the VLB participants. The VL program facilitates weight loss among school-district employees with overweight and obesity by increasing their PA and healthy diet.

Loss of skeletal muscle and inferior muscle quality are associated with poor prognosis in patients undergoing preoperative treatment for pancreatic cancer, so maintaining skeletal muscle health before surgery may help accelerate patients’ functional recovery and improve their quality of life following surgery. While exercise helps maintain or increase skeletal muscle in individuals undergoing cancer treatment, its efficacy during pancreatic cancer treatment is unclear. Accordingly, in this study we compared changes in skeletal muscle quantity (skeletal muscle index [SMI]) and quality (skeletal muscle density [SMD]) during preoperative pancreatic cancer treatment in participants in a home-based exercise program (EP) and a historical cohort of patients who received the usual care (UC) with no formal exercise programming. Recommendations for the EP cohort included both aerobic and resistance exercise. We assessed changes in SMI and SMD using computed tomography scans administered at treatment planning (T0, prior to EP enrollment) and preoperative restaging (T1) for 33 EP and 64 UC patients and compared changes between groups. The UC patients had statistically significant SMI decreases from T0 to T1 (−1.4 ± 3.8 cm2/m2; p = .005), while the EP patients did not (0.2 ± 3.2 cm2/m2; p = .7). The SMI loss was significantly worse for the UC than for the EP patients (p = .03). Neither group demonstrated statistically significant changes in SMD from T0 to T1, nor did the groups differ in the amount of change in SMD. An adjusted linear regression model demonstrated that EP participation was significantly associated with better SMI maintenance (p = .02). These results suggest that participation in a home-based EP during preoperative treatment may help improve skeletal muscle health and clinical and quality of life outcomes for pancreatic cancer survivors.

Background Endometrial cancer survivors are at an increased risk of poor quality of life outcomes. Physical activity is positively associated with general quality of life in this population, however, little is known about how changes in physical activity may be associated with changes in specific aspects of quality of life. The aim of this secondary data analysis was to explore the relationships between change in physical activity and change in physical, mental, social, and other aspects of quality of life in endometrial cancer survivors receiving a physical activity intervention. Methods Endometrial cancer survivors ( N  = 100) participated in a telephone-based physical activity intervention for six months. At baseline and post-intervention we measured physical activity via accelerometry and ecological momentary assessment, and quality of life via the Short Form Health Survey (SF-36), the Quality of Life of Adult Cancer Survivors instrument, the Brief Symptom Inventory, the Pittsburgh Sleep Quality Index, and the Perceived Stress Scale. We conducted structural equation modeling path analyses to investigate how physical activity post-intervention was associated with the quality of life measures’ subscales post-intervention, adjusting for baseline levels and potentially confounding covariates. Results Increasing physical activity was positively associated with improvements in general health ( p  = .044), role limitation due to physical health ( p  = .005), pain ( p  = .041), and somatic distress ( p  = .023). There was no evidence to indicate that change in physical activity was associated with change in other aspects of quality of life. Conclusions Endometrial cancer survivors are at higher risk for suffering from challenges to physical quality of life, and findings from this study suggest that increasing physical activity may alleviate some of these problems. Further research is needed to determine whether other aspects of quality of life are linked to change in physical activity.

PurposeGuidelines recommend exercise to cancer survivors, but limited data exists regarding exercise among patients undergoing preoperative cancer treatment. We examined differences in weekly self-reported exercise and accelerometer-measured physical activity among participants in a home-based exercise program administered during preoperative treatment for pancreatic cancer.MethodsParticipants were encouraged to perform at least 60 min/week of moderate-intensity aerobic exercise and at least 60 min/week of full-body strengthening exercises concurrent with chemotherapy, chemoradiation therapy or both sequentially and received resistance equipment, program instruction, and biweekly follow-up calls to encourage adherence. Self-reported aerobic and strengthening exercise minutes were measured using daily logs, and physical activity was measured objectively using accelerometers.ResultsFifty participants (48% female, mean age 66 ± 8 years) participated for an average of 16 ± 9 preoperative weeks. Participants reported overall means of 126 ± 83 weekly minutes of aerobic exercise and 39 ± 33 weekly minutes of strengthening exercise in daily logs. Participants performed 158.7 ± 146.7 weekly minutes of accelerometer-measured moderate-to-vigorous physical activity. There were no significant differences in exercise or physical activity between treatment phases.ConclusionsThese findings suggest that it is feasible to target the entire preoperative course for exercise prescription. Although participants exceeded aerobic exercise recommendations on average, we observed low strengthening exercise adherence and wide variability in self-reported exercise and accelerometer physical activity variables. These findings suggest that additional support, including program adaptations, may be necessary to overcome barriers to exercise or improve motivation when prescribing exercise in this clinical scenario.

Purpose Weight gain is common among breast cancer patients and may contribute to poorer treatment outcomes. Most programs target breast cancer survivors after the completion of therapy and focus on weight reduction. This study examined the feasibility and preliminary efficacy of an intervention designed to prevent primary weight gain among women receiving neoadjuvant chemotherapy for breast cancer. Methods Thirty-eight newly diagnosed stage II or III breast cancer patients were randomized to the BALANCE intervention or usual care within 3 weeks of starting neoadjuvant chemotherapy. The intervention used a size acceptance-based approach and encouraged home-based resistance and moderate-intensity aerobic exercise as well as a low energy-dense diet to prevent weight gain. Assessments were conducted at baseline, mid-chemotherapy (3 months), and post-chemotherapy (6 months). Intervention feasibility, acceptability, and preliminary effects on anthropometric, quality of life, and circulating biomarker measures were evaluated. Results Intervention participant retention (100%) and in-person session attendance (80%) were high during the intervention period, although attendance dropped to 43% for telephone-delivered sessions. The majority of participants reported being satisfied with the intervention during chemotherapy (88%). Participants in the intervention group had greater reductions in waist circumference ( p  = .03) and greater improvements in self-reported vitality scores ( p  = .03) than the control group at the end of chemotherapy. Significant effects on biomarkers were not observed. Conclusions A size acceptance weight management program is feasible during neoadjuvant chemotherapy among breast cancer patients and may have beneficial effects on waist circumference and patient vitality.
