RESUMO
PURPOSE: Physical activity (pre- and post-diagnosis) has been studied in prevention and survivorship contexts for endometrial cancer. However, the association of physical activity (PA) across the lifespan on mortality risk among endometrial cancer survivors is understudied. The study's objective was to identify the association of lifetime PA on mortality risk in endometrial cancer survivors. METHODS: Seven hundred forty-five endometrial cancer survivors drawn from a population-based cancer registry (diagnosed between 1991 and 1994) reported the frequency (sessions/week) of moderate- and vigorous intensity physical activity (MVPA) at age 12, age 20, and 5 years pre-interview (post-diagnosis). Cox proportional hazards were used to estimate hazard ratios (HR) and 95% confidence intervals for the association between PA, all-cause, and cardiovascular disease mortality as assessed in 2016. MVPA was modeled using natural cubic splines. RESULTS: Diagnosis age, body mass index, and smoking (pack-years) were each positively associated with increased all-cause mortality risk. Those who did one session of MVPA 5 years pre-interview had a lower mortality risk (HR 0.61; 95% CI 0.41-0.92) compared to those with no MVPA. Those reporting one session of MVPA was similarly observed at age 12 (HR 0.95; 95% CI 0.86-1.06) and at age 20 (HR 0.87; 95% CI 0.65-1.16). CONCLUSION: Those who participated in PA, compared to those who did not, in the 5 years before diagnosis had a lower mortality risk. While PA was not independently protective against mortality risk at ages 12 or 20, PA is still important for endometrial cancer survivors for other non-mortality outcomes.

PURPOSE: Endometrial cancer is strongly linked to obesity and inactivity; however, increased physical activity has important benefits even in the absence of weight loss. Resistance (strength) training can deliver these benefits; yet few women participate in resistance exercise. The purpose of this study was to describe both physiological and functional changes following a home-based strength training intervention. METHODS: Forty post-treatment endometrial cancer survivors within 5 years of diagnosis were enrolled in a pilot randomized trial, comparing twice-weekly home-based strength exercise to wait list control. Participants conducted the exercises twice per week for 10 supervised weeks with 5 weeks of follow-up. Measures included DXA-measured lean mass, functional fitness assessments, blood biomarkers, and quality of life outcomes. RESULTS: On average, participants were 60.9 years old (SD = 8.7) with BMI of 39.9 kg/m2 (SD = 15.2). At baseline, participants had 51.2% (SD = 6.0) body fat, which was not different between groups. Improvements were seen in the 30-s chair sit to stand (d = .99), the 30-s arm curl (d = .91), and the 8-ft up-and-go test (d = .63). No changes were measured for HbA1c or C-reactive protein. No changes were observed for flexibility (chair sit and reach, back scratch tests), 6-min walk test, maximum handgrip test, anxiety, depression, fatigue, or self-efficacy for exercise. CONCLUSIONS: Home-based muscle-strengthening exercise led to favorable and clinically relevant improvements in 3 of 7 physical function assessments. Physical function, body composition, blood biomarkers, and patient-reported outcomes were feasible to measure. These fitness improvements were observed over a relatively short time frame of 10 weeks.

Despite the health benefits of physical activity, many women remain inactive and the needs of rural women are understudied. To understand access to physical activity barriers, opportunities, and intervention preferences in rural women and determine how these differ by self-reported activity level. A mailed questionnaire was distributed to 900 rural women and included measures of physical activity, health status, barriers, opportunities for exercise, and preferences for intervention type, components, and delivery. Questionnaires were completed by 507 women; 72.0% reported meeting the physical activity guideline. Inactive women reported greater barriers to activity (higher scores on 18 of 22 barriers; p < 0.05), less access to or usage of 8 of 9 places to exercise (p < 0.05), and less belief in the relevance of physical activity to personal health (p < 0.001). Both inactive and active women were most interested in programs that use walking, yoga, or strength training. Physical activity interventions for rural women need to address their specific needs, including barriers to physical activity and lower access to places in which to be physically active.

PURPOSE: Rehabilitation services are recommended by clinical practice guidelines following breast cancer treatment, yet little is known about how utilization may vary by patient-level characteristics which we aimed to study using SEER-Medicare data. METHODS: Data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database was used to identify non-metastatic breast cancer survivors aged ≥ 66 years diagnosed between 2011 and 2016. Rehabilitation services delivered 0-11 months post-diagnosis were identified via outpatient or physician visit claims. Descriptive statistics and associations between patient characteristics and rehabilitation services were calculated using modified Poisson models estimating relative risk (RR) and corresponding 95% confidence intervals (CIs). RESULTS: Of 55,539 breast cancer survivors, 33% (n = 18,244) had received any type of rehabilitative services. Survivors were a mean age of 75 years (SD 6.7), 88% White, 86% urban-dwelling, and 21% Medicare/Medicaid dually enrolled. In adjusted models, patients aged > 75 vs. ≤ 75 were 6% (RR 0.94, 95% CI 0.92-0.96) less likely to have received rehabilitative services. Survivors in an area with greater educational attainment vs. less educational attainment, White vs. non-White, or living in a rural vs. urban area were 26% (1.26, CI 1.22-1.30), 6% (1.06, CI 1.02-1.11), and 6% (1.06, CI 1.02-1.10) more likely to have received rehabilitative services, respectively. CONCLUSION: The largest differences in rehabilitation utilization were observed for survivors of differing educational and treatment statuses. IMPLICATIONS FOR CANCER SURVIVORS: Further research is needed on barriers, access, and delivery of rehabilitation services, specifically for breast cancer survivors who are older-aged, non-White, or Medicare/Medicaid dual eligible.
RESUMO
Importance: Higher physical activity levels are associated with lower risks of cancer, cardiovascular disease, and diabetes, but associations with many common and less severe health conditions are not known. These conditions impose large health care burdens and reduce quality of life. Objectives: To investigate the association between accelerometer-measured physical activity and the subsequent risk of hospitalization for 25 common reasons for hospitalization and to estimate the proportion of these hospitalizations that might have been prevented if participants had higher levels of physical activity. Design, Setting, and Participants: This prospective cohort study used data from a subset of 81 717 UK Biobank participants aged 42 to 78 years. Participants wore an accelerometer for 1 week (between June 1, 2013, and December 23, 2015) and were followed up over a median (IQR) of 6.8 (6.2-7.3) years; follow-up for the current study ended in 2021 (exact date varied by location). Exposures: Mean total and intensity-specific accelerometer-measured physical activity. Main Outcomes and Measures: Hospitalization for the most common health conditions. Cox proportional hazards regression analysis was used to estimate hazard ratios (HRs) and 95% CIs for mean accelerometer-measured physical activity (per 1-SD increment) and risks of hospitalization for 25 conditions. Population-attributable risks were used to estimate the proportion of hospitalizations for each condition that might be prevented if participants increased their moderate to vigorous physical activity (MVPA) by 20 minutes per day. Results: Among 81 717 participants, the mean (SD) age at accelerometer assessment was 61.5 (7.9) years; 56.4% were female, and 97.0% self-identified as White. Higher levels of accelerometer-measured physical activity were associated with lower risks of hospitalization for 9 conditions: gallbladder disease (HR per 1 SD, 0.74; 95% CI, 0.69-0.79), urinary tract infections (HR per 1 SD, 0.76; 95% CI, 0.69-0.84), diabetes (HR per 1 SD, 0.79; 95% CI, 0.74-0.84), venous thromboembolism (HR per 1 SD, 0.82; 95% CI, 0.75-0.90), pneumonia (HR per 1 SD, 0.83; 95% CI, 0.77-0.89), ischemic stroke (HR per 1 SD, 0.85; 95% CI, 0.76-0.95), iron deficiency anemia (HR per 1 SD, 0.91; 95% CI, 0.84-0.98), diverticular disease (HR per 1 SD, 0.94; 95% CI, 0.90-0.99), and colon polyps (HR per 1 SD, 0.96; 95% CI, 0.94-0.99). Positive associations were observed between overall physical activity and carpal tunnel syndrome (HR per 1 SD, 1.28; 95% CI, 1.18-1.40), osteoarthritis (HR per 1 SD, 1.15; 95% CI, 1.10-1.19), and inguinal hernia (HR per 1 SD, 1.13; 95% CI, 1.07-1.19), which were primarily induced by light physical activity. Increasing MVPA by 20 minutes per day was associated with reductions in hospitalization ranging from 3.8% (95% CI, 1.8%-5.7%) for colon polyps to 23.0% (95% CI, 17.1%-28.9%) for diabetes. Conclusions and Relevance: In this cohort study of UK Biobank participants, those with higher physical activity levels had lower risks of hospitalization across a broad range of health conditions. These findings suggest that aiming to increase MVPA by 20 minutes per day may be a useful nonpharmaceutical intervention to reduce health care burdens and improve quality of life.

Introduction/Purpose: Due to the coronavirus disease 2019 (COVID-19) pandemic, many in-person cancer exercise and rehabilitation programs necessarily transitioned to virtual formats to meet the needs of individuals living with and beyond cancer. The purpose of this study was to qualitatively assess program-level facilitators and barriers to virtual exercise program implementation and to identify preferred strategies to overcome implementation barriers. Methods: US-based virtual cancer exercise and rehabilitation programs were recruited from professional networks via an emailed screening questionnaire. Eligible programs identified a point of contact for a 1:1 semi-structured interview to discuss program-level barriers and facilitators to implementing virtual exercise programs. Interview transcript analysis was conducted via inductive coding techniques using NVivo software. Barriers were categorized according to the Consolidated Framework for Implementation Research and a prioritized list of strategies to support implementation was created by mapping barriers to a list of Expert Recommendations for Implementing Change. Results: Of the 41 unique responses received, 24 program representatives completed semi-structured interviews. Interviewees represented individual programs, community-based programs, and hospital-based cancer exercise/rehabilitation programs. Analysis showed high correlation between facilitators and barriers by program type, with both program- and individual-level strategies used to implement exercise programs virtually. Strategies that ranked highest to support implementation include promoting program adaptability, building a coalition of stakeholders and identifying program champions, developing an implementation blueprint, altering organizational incentives and allowances, providing education across stakeholder groups, and accessing funding. Conclusions: Learning from the transition of cancer exercise and rehabilitation programs to virtual formats due to the COVID-19 pandemic, we identify program-level barriers and facilitators encountered in the implementation of virtual programs and highlight implementation strategies that are most relevant to overcome common barriers. We present a roadmap for programs to use these strategies for future work in virtual exercise and rehabilitation program implementation.
RESUMO
Importance: Higher amounts of physical activity are associated with increased longevity. However, whether different leisure time physical activity types are differentially associated with mortality risk is not established. Objectives: To examine whether participation in equivalent amounts of physical activity (7.5 to <15 metabolic equivalent of task [MET] hours per week) through different activity types is associated with mortality risk and to investigate the shape of the dose-response association. Design, Setting, and Participants: Participants in this cohort were respondents from the National Institutes of Health-AARP Diet and Health Study who completed the follow-up questionnaire between 2004 and 2005. This questionnaire collected data on weekly durations of different types of physical activities. Mortality was ascertained through December 31, 2019. Exposures: MET hours per week spent participating in the following activities: running, cycling, swimming, other aerobic exercise, racquet sports, golf, and walking for exercise. Main Outcomes and Measures: All-cause, cardiovascular, and cancer mortality. Separate multivariable-adjusted Cox proportional hazards regression models were fitted to estimate hazard ratios (HRs) and 95% CIs of mortality for each of the 7 types of leisure time physical activities, as well as the sum of these activities. Results: A total of 272â¯550 participants (157â¯415 men [58%]; mean [SD] age at baseline, 70.5 [5.4] years [range, 59-82 years]) provided information on types of leisure time activity, and 118â¯153 (43%) died during a mean (SD) follow-up of 12.4 (3.9) years. In comparison with those who did not participate in each activity, 7.5 to less than 15 MET hours per week of racquet sports (HR, 0.84; 95% CI, 0.75-0.93) and running (HR, 0.85; 95% CI, 0.78-0.92) were associated with the greatest relative risk reductions for all-cause mortality, followed by walking for exercise (HR, 0.91; 95% CI, 0.89-0.93), other aerobic activity (HR, 0.93; 95% CI, 0.90-0.95), golf (HR, 0.93; 95% CI, 0.90-0.97), swimming (HR, 0.95; 95% CI, 0.92-0.98), and cycling (HR, 0.97; 95% CI, 0.95-0.99). Each activity showed a curvilinear dose-response association with mortality risk; low MET hours per week of physical activity for any given activity type were associated with a large reduction in mortality risk, with diminishing returns for each increment in activity thereafter. Associations were similar for cardiovascular and cancer mortality. Conclusions and Relevance: This cohort study of older individuals found differences between different types of leisure time activities and mortality risk, but there were significant associations between participating in 7.5 to less than 15 MET hours per week of any activity and mortality risk.
