Breaking Up Sedentary Behavior: Perceptions From Cancer Survivors

Association between Physical Activity and Quality of Life in Colorectal Cancer Patients with Postoperative Defecatory Dysfunction: A Preliminary Survey

In this study, we aimed to explore the association between physical activity (PA) and quality of life (QoL) in colorectal cancer (CRC) patients with postoperative defecatory dysfunction. A survey using the European Organization for Research and Treatment of Cancer QLQ-30 and QLQ-29 was conducted among 62 adult outpatients with CRC at two cancer hospitals in Japan. PA and sedentary behavior were evaluated using the Global Physical Activity Questionnaire. Multiple regression analysis was performed, incorporating the QoL as the outcome, with the total PA and its three domains (occupational, transportation, and recreational) and sedentary time as exposures, while controlling for age, sex, and tumor location. The analyses revealed that patients engaged in PA ≥ 150 min/week (67.4 points; 95% confidence interval [CI]: 21.1, 113.8) and recreational PA ≥ 30 min/week (56.0 points; 95% CI: 2.3, 109.7) had significantly higher function scores. Conversely, sedentary time >8 h/day or occupational PA duration ≥30 min/week was associated with poor symptom and function scores. These findings highlight the importance of promoting recreational PA and reducing sedentary behavior to maintain and improve the QoL in CRC patients with defecatory dysfunction.

[Self-sense and experiences of physical activity in breast cancer survivors: Qualitative evidence synthesis]

Breast cancer has a high incidence rate and a negative impact on women's lives. The practice of physical activity (PA) has shown strong evidence in controlling the side effects associated with the disease and its treatment. However, having an active lifestyle is influenced by socio-health inequities. The objective was to analyze the categories related to the meanings and perceived experiences with PA in breast cancer survivors (BCS). Protocol https://osf.io/7fwbs/. Articles describing the meanings of PA in BCS published after 2010 were included. Fourteen articles were analyzed using line-by-line coding. The emerging categories were: 1)PA as a strategy to re-signify and empower the body. 2)Cancer means a change in PA trajectories. 3)PA is a tool for a healthy and functional body in everyday life.

Exploring sedentary behavior during neo- or adjuvant treatment in patients with cancer: A phenomenological study

PURPOSE

Increased sedentary behavior during cancer treatment is common, which may have negative long-term health effects. Understanding patients' experience of sedentary behavior during neo- or adjuvant cancer treatment may be crucial in developing effective support for patients to reduce sedentary behavior. Therefore, the present study aimed to explore sedentary behavior in patients undergoing neo- or adjuvant cancer treatment.

METHODS

Eleven interviews were conducted with patients undergoing treatment for breast, prostate, and colorectal cancer. Participants were recruited from a university hospital in Sweden. Interviews were analyzed phenomenologically, and the results were presented as descriptions of the phenomenon sedentary behavior.

RESULTS

The overarching theme of sedentary behavior during cancer treatment was that sedentary behavior is experienced through being physically active or not. Furthermore, experiences of sedentary behavior increased with side effects and varied depending on the type and phase of cancer treatment, meaning that sedentary behavior is an adjustment to side effects. Additionally, sedentary behavior was influenced by life circumstances and social interaction, such as work status and having social support. Finally, sedentary behavior is influenced by strategies and motivations, such as the perceived benefits of physical activity and self-image.

CONCLUSIONS

Sedentary behavior is difficult for patients to discern, which is why health care personnel may need to help patients by increasing awareness of the negative impact of sedentary behavior in a way that does not stigmatize patients. Furthermore, developing support that targets periods with more side effects and helping patients reduce sedentary behavior throughout changing life circumstances may be helpful.

Reallocating Time to Physical Activity and Sleep: Associations with Body Mass Index in Cancer Survivors

BACKGROUND

Body mass index (BMI) above ≥ 25 kg/m2 is associated with increased risk for cancer-related morbidity and mortality. Achieving recommended amounts of physical activity (PA), sedentary time (ST), and sleep can help cancer survivors (CS) attain a healthy BMI. This cross-sectional study examined the potential role of reallocating time between moderate and light PA, ST, and sleep on BMI in CS.

METHOD

A sample of CS (N = 73, Mage = 53.7 ± 12.9) wore an activPAL and Actiwatch accelerometer for 7 days, 24 h per day to measure PA intensity and sleep, respectively. Self-reported height and weight or scale/stadiometer were used to calculate BMI. Isotemporal substitution models were used to reallocate time, averaged over the 7-day period, from one activity of interest to another and examine the associations with BMI. Statistical significance was set at p < .05.

RESULTS

The following reallocations of 30 min were significantly associated with BMI: sleep to ST (+ 0.80 kg/m2, p = 0.02) and ST to light PA (- 0.53 kg/m2, p = 0.008). No significant associations with BMI were observed for reallocating time to or away from moderate-vigorous PA.

CONCLUSION

The results of this study suggest that sleep and light PA may have important implications for achieving a healthy BMI in CS. Therefore, future research should include interventions which target light PA and sleep to determine if they can improve BMI in CS.

Association Between Physical Activity, Sedentary Behaviors, and Sleep-Related Outcomes Among Cancer Survivors: a Cross-Sectional Study

BACKGROUND

Limited research has examined the association between moderate to vigorous physical activity (MVPA), sedentary behavior (SB), and sleep-related outcomes in cancer survivors. Therefore, this study aimed to examine these associations using a nationally representative sample of US adults.

METHODS

Data from the 2005-2018 National Health and Nutrition Examination Survey (NHANES) were analyzed. A total of 3229 adults with cancer histories were included. Physical activity was measured through accelerometry, and questions on daily activities, sedentary time, and sleep were collected during the household interview. Weighted multivariable analyses were conducted after accounting for the complex sampling design of the NHANES dataset.

RESULTS

After adjustments, physical activity and SB outcomes were associated with several self-reported sleep-related parameters. Increases in minutes of self-reported MVPA and SB were associated with a decreased likelihood of reporting ≥ 8 h of sleep (OR = 0.92, 95% CI = 0.86, 0.99 and OR = 0.88, 95% CI = 0.82, 0.95). Converse associations were found between device-measured MVPA and SB with the likelihood of reporting often/always feeling overly sleepy during the day (OR = 0.86, 95% CI = 0.75 and OR = 1.13, 95% CI = 1.05, respectively). However, an increased likelihood of waking up too early in the morning (OR = 1.22, 95% CI = 1.04) was observed with increases in minutes of device-measured MVPA.

CONCLUSIONS

A sensible strategy to decrease the frequency of sedentary breaks and increase minutes of physical activity throughout the day may reduce sleep complaints reported in cancer survivors.

Associations of Physical Activity and Handgrip Strength with Health-Related Quality of Life in Older Korean Cancer Survivors

Background: Uncertainty exists regarding the associations between physical activity (PA), relative handgrip strength (RHGS), and health-related quality of life (HRQoL) among elderly Korean cancer survivors. This study investigated the moderating effect of RHGS on the relationship between PA and HRQoL in 308 cancer survivors aged ≥65 years using the data from the Korean National Health and Nutrition Examination Survey in 2014−2019. Methods: HRQoL was evaluated with the EuroQol-5-dimension instrument. PA and handgrip strength were assessed with the Global Physical Activity Questionnaire and a hand dynamometer, respectively. Age, sex, body mass index, income, marital status, educational background, heavy alcohol consumption, smoking status, multimorbidity, and hemoglobin were included as covariates. Results: Bivariate logistic regression showed that insufficient PA and no PA were associated with higher odds of a low HRQoL (odds ratio, OR = 2.6, 95% confidence interval, CI = 1.3~5.1, p = 0.005; OR = 2.4, 95% CI = 1.1~5.0, p = 0.024, respectively), compared with sufficient PA (OR = 1). Weak RHGS was associated with high odds of a low HRQoL (OR = 2.6, 95%= 1.530~4.6, p < 0.001) compared with normal RHGS (OR = 1). Particularly, RHGS (β = −0.0573, 95% CI = −0.1033~−0.0112) had a significant moderating effect on the relationship between PA and HRQoL even after adjustments for all the covariates. The negative influence of physical inactivity on HRQoL was observed in cancer survivors with weak RHGS but not in cancer survivors with normal RHGS. Conclusions: The current findings suggest that maintaining or promoting muscular strength through regular exercise is critical for the HRQoL of elderly Korean cancer survivors.

Are Physical Activity and Sedentary Behavior Associated With Cancer-Related Symptoms in Real Time?: A Daily Diary Study

BACKGROUND

Few studies have examined the real-time and dynamic relationship between lifestyle behaviors and treatment-related symptoms.

OBJECTIVE

The aim of this study was to examine the associations of daily physical activity and sedentary behavior with symptom burden, pain interference, and fatigue among patients who were undergoing active cancer treatment.

METHODS

A total of 22 (mean age = 57 years; 73% women; 55% Black) cancer patients were recruited from a local hospital and reported a daily diary of physical activity, sedentary behavior, symptom burden, pain interference, and fatigue over 10 days. Adjusted mixed-effects models were used to examine all associations.

RESULTS

Body mass index moderated the relationship between physical activity and symptom burden (γ = 0.06, P < .01) and physical activity and fatigue (γ = 0.09, P < .05). On days where physical activity was higher than average, symptom burden and fatigue scores were lower among patients who had lower body mass index values. Also, age moderated the relationship between sedentary behavior and symptom burden (γ = -0.04, P < .05); on days where patients sat more, symptom burden was lower among patients who were younger than the average age.

CONCLUSIONS

Overall, these data indicate that treatment-related symptoms vary daily within cancer patients and that physical activity may alleviate treatment-related symptoms for leaner patients. Larger samples and objective assessments of physical activity and sedentary behavior are needed to validate our results.

IMPLICATIONS FOR PRACTICE

Oncology nurses may be in the best position to promote physical activity during treatment as a strategy to manage symptom burden.

IMPROVE, a community-based exercise intervention versus support group to improve functional and health outcomes among older African American and Non-Hispanic White breast cancer survivors from diverse socioeconomic backgrounds: Recruitment strategies and baseline characteristics

BACKGROUND

Behavioral intervention studies in older breast cancer survivors, particularly older African American (AA) and socioeconomic status-disadvantaged breast cancer survivors, are lacking. To inform future studies, the authors examined recruitment strategies in older breast cancer survivors who participated in an exercise intervention study.

METHODS

IMPROVE is a randomized trial designed to evaluate a group-based exercise intervention versus a support group (ClinicalTrials.gov identifier, NCT02763228). Participants were aged ≥65 years who had survived stage I through III breast cancer and were within 5 years of treatment completion. Participants were recruited through multiple approaches, including peripheral, linguistic, and constituent-involving strategies that incorporated the identification of potentially eligible patients from 3 local hospitals and from State of Ohio registries and through direct clinician and community organization referrals.

RESULTS

Between October 2016 and November 2019, 7487 patients were screened, 4790 were potentially eligible, and 213 were randomized into the study. The eligible:randomization rates were 4.4% overall and 84%, 8%, and 2% for recruitment using direct referrals, hospital registries, and state registries, respectively. The median age of the randomized cohort was 70 years (range, 65-88 years) and included 44% AA and 44% socioeconomic status-disadvantaged breast cancer survivors. Compared with all registry-eligible patients, directly referred-eligible patients were more likely to be AA versus Non-Hispanic White (41% vs 19%; P = .006), to be contacted successfully (100% vs 33%; P < .0001), and to accept study participation (88% vs 16%; P < .0001).

CONCLUSIONS

Direct referrals appeared to be the most efficient strategy for recruiting AA survivors. Behavioral intervention studies seeking to target older AA and socioeconomic status-disadvantaged breast cancer survivors should include strategies that foster direct referrals to study participation.

Sedentary behavior among breast cancer survivors: a longitudinal study using ecological momentary assessments

PURPOSE

Sedentary behavior (SB) or any waking behavior ≤ 1.5 METs is associated with an increase in body weight and fatigue and poor quality of life among cancer survivors. The purpose of this study was to explore longitudinal trends in SB using accelerometers and associated variables via ecological momentary assessments (EMA) among breast cancer survivors.

METHODS

Breast cancer survivors (within 5 years post-diagnosis) were recruited for a 12-month observational study. Participants were asked to download an EMA application to their smartphones to receive prompts for 7 days and to concurrently wear an Actigraph accelerometer. Participants responded to 35 prompts during each 7-day assessment period at baseline, and at 3, 6, 9, and 12 months. Within each prompt, participants were asked questions about their current level of affect, sadness, anxiety, stress, worry and fatigue, and cancer-related symptoms (e.g., neuropathy).

RESULTS

Twenty-two survivors (mean age = 51.5 years) were recruited and 20 participants completed the study. Mean baseline SB averaged 76.7 h/week. Univariate longitudinal models suggested higher levels of sadness, anxiety, stress, worry, and fatigue were associated with more SB while more positive affect was associated with less SB. Additionally, non-leisure context (work) was associated with more SB. Autoregressive models indicated cross-lagged effects of affective valence, fatigue, and SB.

CONCLUSIONS

More negative affective valence and higher fatigue were associated with more SB. Reducing negative affect valence and offering non-sedentary approaches to manage fatigue may help reduce SB.

IMPLICATIONS FOR CANCER SURVIVORS

Specific interventions are needed to reduce SB among cancer survivors-particularly those that target negative affect valence and fatigue.

A Real-Time Mobile Intervention to Reduce Sedentary Behavior Before and After Cancer Surgery: Usability and Feasibility Study

BACKGROUND

Sedentary behavior (SB) is common after cancer surgery and may negatively affect recovery and quality of life, but postoperative symptoms such as pain can be a significant barrier to patients achieving recommended physical activity levels. We conducted a single-arm pilot trial evaluating the usability and acceptability of a real-time mobile intervention that detects prolonged SB in the perioperative period and delivers prompts to walk that are tailored to daily self-reported symptom burden.

OBJECTIVE

The aim of this study is to develop and test a mobile technology-supported intervention to reduce SB before and after cancer surgery, and to evaluate the usability and feasibility of the intervention.

METHODS

A total of 15 patients scheduled for abdominal cancer surgery consented to the study, which involved using a Fitbit smartwatch with a companion smartphone app across the perioperative period (from a minimum of 2 weeks before surgery to 30 days postdischarge). Participants received prompts to walk after any SB that exceeded a prespecified threshold, which varied from day to day based on patient-reported symptom severity. Participants also completed weekly semistructured interviews to collect information on usability, acceptability, and experience using the app and smartphone; in addition, smartwatch logs were examined to assess participant study compliance.

RESULTS

Of eligible patients approached, 79% (15/19) agreed to participate. Attrition was low (1/15, 7%) and due to poor health and prolonged hospitalization. Participants rated (0-100) the smartphone and smartwatch apps as very easy (mean 92.3 and 93.2, respectively) and pleasant to use (mean 93.0 and 93.2, respectively). Overall satisfaction with the whole system was 89.9, and the mean System Usability Scale score was 83.8 out of 100. Overall compliance with symptom reporting was 51% (469/927 days), decreasing significantly from before surgery (264/364, 73%) to inpatient recovery (32/143, 22%) and postdischarge (173/420, 41%). Overall Fitbit compliance was 70% (653/927 days) but also declined from before surgery (330/364, 91%) to inpatient (51/143, 36%) and postdischarge (272/420, 65%).

CONCLUSIONS

Perioperative patients with cancer were willing to use a smartwatch- and smartphone-based real-time intervention to reduce SB, and they rated the apps as very easy and pleasant to use. Compliance with the intervention declined significantly after surgery. The effects of the intervention on postoperative activity patterns, recovery, and quality of life will be evaluated in an ongoing randomized trial.

The Social Context of Sedentary Behaviors and Their Relationships With Health in Later Life

This study examined sedentary behaviors among older adults and explored associations with social context and health measures using cross-sectional data from the National Health and Aging Trends Study (N = 1,687). Multivariate models were estimated to explore associations of time in six sedentary behaviors (i.e., television watching, sitting and talking, hobbies, computer use, driving, and resting) with sociodemographic characteristics and level of social engagement and with health status. Results indicated substantial variability in sedentary behaviors, with television watching being the most frequent and resting the least frequent activities. Sedentary behaviors varied by sociodemographic characteristics, including age, race/ethnicity, and education, as well as by level of social engagement. Television watching and resting, but not other behaviors, were associated with poorer health. These findings help to unpack the role of social context in sedentary behaviors and could inform public health interventions aimed at reducing time spent in behaviors that are adversely associated with health.

Exploring adults' experiences of sedentary behaviour and participation in non-workplace interventions designed to reduce sedentary behaviour: a thematic synthesis of qualitative studies

BACKGROUND

Sedentary behaviour is any waking behaviour characterised by an energy expenditure of ≤1.5 metabolic equivalent of task while in a sitting or reclining posture. Prolonged bouts of sedentary behaviour have been associated with negative health outcomes in all age groups. We examined qualitative research investigating perceptions and experiences of sedentary behaviour and of participation in non-workplace interventions designed to reduce sedentary behaviour in adult populations.

METHOD

A systematic search of seven databases (MEDLINE, AMED, Cochrane, PsychINFO, SPORTDiscus, CINAHL and Web of Science) was conducted in September 2017. Studies were assessed for methodological quality and a thematic synthesis was conducted. Prospero database ID: CRD42017083436.

RESULTS

Thirty individual studies capturing the experiences of 918 individuals were included. Eleven studies examined experiences and/or perceptions of sedentary behaviour in older adults (typically ≥60 years); ten studies focused on sedentary behaviour in people experiencing a clinical condition, four explored influences on sedentary behaviour in adults living in socio-economically disadvantaged communities, two examined university students' experiences of sedentary behaviour, two on those of working-age adults, and one focused on cultural influences on sedentary behaviour. Three analytical themes were identified: 1) the impact of different life stages on sedentary behaviour 2) lifestyle factors influencing sedentary behaviour and 3) barriers and facilitators to changing sedentary behaviour.

CONCLUSIONS

Sedentary behaviour is multifaceted and influenced by a complex interaction between individual, environmental and socio-cultural factors. Micro and macro pressures are experienced at different life stages and in the context of illness; these shape individuals' beliefs and behaviour related to sedentariness. Knowledge of sedentary behaviour and the associated health consequences appears limited in adult populations, therefore there is a need for provision of accessible information about ways in which sedentary behaviour reduction can be integrated in people's daily lives. Interventions targeting a reduction in sedentary behaviour need to consider the multiple influences on sedentariness when designing and implementing interventions.

Health Behaviors and Lifestyle Interventions in African American Breast Cancer Survivors: A Review

Background: African American breast cancer survivors have a higher incidence of estrogen receptor negative and basal-like (e.g., triple negative) tumors, placing them at greater risk for poorer survival when compared to women of other racial and ethnic groups. While access to equitable care, late disease stage at diagnosis, tumor biology, and sociodemographic characteristics contribute to health disparities, poor lifestyle characteristics (i.e., inactivity, obesity, and poor diet) contribute equally to these disparities. Lifestyle interventions hold promise in shielding African American survivors from second cancers, comorbidities, and premature mortality, but they are often underrepresented in studies promoting positive behaviors. This review examined the available literature to document health behaviors and lifestyle intervention (i.e., obesity, physical activity, and sedentary behavior) studies in African American breast cancer survivors. Methods: We used PubMed, Academic Search Premier, and Scopus to identify cross-sectional and intervention studies examining the lifestyle behaviors of African American breast cancer survivors. Identified intervention studies were assessed for risk of bias. Other articles were identified and described to provide context for the review. Results: Our systematic review identified 226 relevant articles. The cross-sectional articles indicated poor adherence to physical activity and dietary intake and high rates of overweight and obesity. The 16 identified intervention studies indicated reasonable to modest study adherence rates (>70%), significant reductions in weight (range -1.9 to -3.6%), sedentary behavior (-18%), and dietary fat intake (range -13 to -33%) and improvements in fruit and vegetable intake (range +25 to +55%) and physical activity (range +13 to +544%). The risk of bias for most studies were rated as high (44%) or moderate (44%). Conclusions: The available literature suggests that African American breast cancer survivors adhere to interventions of various modalities and are capable of making modest to significant changes. Future studies should consider examining (a) mediators and moderators of lifestyle behaviors and interventions, (b) biological outcomes, and (c) determinants of enhanced survival in this population.

Breast, Prostate, and Colorectal Cancer Survivors' Experiences of Using Publicly Available Physical Activity Mobile Apps: Qualitative Study

BACKGROUND

Physical activity (PA) can improve a range of outcomes following a cancer diagnosis. These include an improvement in experience of side effects of treatment (eg, fatigue) and management of comorbid conditions. PA might also increase survival and reduce recurrence. Digital interventions have shown potential for PA promotion among cancer survivors, but most in a previous review were Web-based, and few studies used mobile apps. There are many PA apps available for general public use, but it is unclear whether these are suitable as a PA intervention after a cancer diagnosis.

OBJECTIVE

This study sought posttreatment nonmetastatic breast, prostate, and colorectal cancer survivors' opinions of using smartphone apps to promote PA and gathered their views on existing publicly available PA apps to inform a future intervention.

METHODS

Each participant was randomly assigned to download 2 of 4 apps (Human, The Walk, The Johnson & Johnson Official 7 Minute Workout, and Gorilla Workout). Participants used each app for 1 week consecutively. In-depth semistructured telephone interviews were then conducted to understand participants' experiences of using the apps and how app-based PA interventions could be developed for cancer survivors. The interviews were analyzed using thematic analysis.

RESULTS

Thirty-two participants took part: 50% (16/32) had prostate cancer, 25% (8/32) had breast cancer, and 25% (8/32) had colorectal cancer. Three core themes were identified. The first theme was that multiple factors affect engagement with PA apps and this is highly personalized. Factors affecting engagement included participants' perceptions of (1) the advantages and disadvantages of using apps to support PA, (2) the relevance of the app to the user (eg, in terms of cancer-related factors, their PA goals, the difficulty level of the app, the way in which they interact with their mobile phone, and the extent to which the app fits with their self-identity), (3) the quality of the app (eg, usability, accuracy, quality of production, and scientific evidence-base), and (4) the behavior change techniques used to promote PA. In the second theme, participants recommended that apps that promote walking are most appealing, as walking removes many barriers to PA. Finally, the participants suggested that PA apps should be integrated into cancer care, as they valued guidance and recommendations from health care professionals.

CONCLUSIONS

This sample of breast, prostate, and colorectal cancer survivors was receptive to the use of apps to promote PA. Although no publicly available PA app was deemed wholly suitable, many suggestions for adaptation and intervention development were provided. The results can inform the development of an app-based PA intervention for cancer survivors. They also highlight the wide-ranging and dynamic influences on engagement with digital interventions, which can be applied to other evaluations of mobile health products in other health conditions and other health behaviors.

A Feasibility Study of Restorative Yoga Versus Vigorous Yoga Intervention for Sedentary Breast and Ovarian Cancer Survivors

Yoga has been shown to improve cancer survivors' quality of life, yet regular yoga practice is a challenge for those who are sedentary. We conducted a pilot randomized controlled study to assess feasibility and adherence of two types of yoga intervention among sedentary cancer survivors. Sedentary breast and ovarian cancer survivors were randomized to practice either restorative yoga (minimal physical exertion, Group R) or vigorous yoga (considerable physical exertion, Group V) in three 60-minute supervised sessions a week for 12 weeks, followed by 12 weeks of home practice. Accrual, adherence, and attendance rates were assessed. Of the 226 eligible patients, 175 (77%) declined to participate in the study, citing time commitment and travel as the most common barriers. Forty-two subjects consented to participate in the study. Of the 35 participants who began the intervention (20 in Group R and 15 in Group V), adherence rate (percentage remaining in the study at week 12) was 100% and 87%, respectively. Rate of adequate attendance (more than 66% of the scheduled supervised sessions) was 85% and 73%, respectively. Rate of completion of the home practice period was 85% and 77%, respectively. In this study, sedentary cancer survivors were able to adhere to a long-term, regular yoga regimen. The rate of adequate attendance was higher for restorative yoga. Future studies for sedentary patients should focus on reducing time commitment and travel requirements to improve recruitment, and on using restorative yoga as a more feasible intervention for this population.
