Exercise barriers in Korean colorectal cancer patients

Psychosocial correlates of physical activity in cancer survivors: a systematic review and meta-analysis

BACKGROUND

Physical activity (PA) is a non-pharmacological approach to optimize health benefits in cancer survivors and is recommended as part of care. However, most cancer survivors fail to meet PA recommendations. The current systematic review and meta-analysis aimed to identify psychosocial correlates of free-living PA in cancer survivors.

METHODS

Three electronic databases were searched (PubMed, PsycINFO, and SportDiscus). Meta-analyses were conducted for psychosocial correlates tested ≥ 3 times.

RESULTS

Sixty-four articles were included. Eighty-eight different free-living PA correlates were identified. Meta-analyses (n = 32 studies) tested 23 PA correlates, of which 16 were significant (p < 0.05). Larger effect sizes (0.30 < ES > 0.45) were found for exercise self-efficacy, perceived behavioral control, intention, lower perceived barriers for exercise, enjoyment, perceived PA benefits, and attitudes. Small-to-moderate effects (0.18 < ES < 0.22) were found for subjective norms, physical functioning, quality of life, depression, and mental health. These findings were generally in line with narrative results.

CONCLUSIONS

This systematic review highlights important psychosocial correlates of free-living PA that can be targeted in future PA promotion interventions for cancer survivors. Constructs mainly from SCT and TPB were the most studied and appear to be associated with free-living PA in this population. However, we cannot currently assert which frameworks might be more effective. Further studies of better methodological quality, per correlate and theory, exploring longer-term associations and across different types of cancer, are needed.

IMPLICATIONS FOR CANCER SURVIVORS

Having higher exercise self-efficacy, perceived behavioral control, intention, enjoyment and perceived PA benefits, more positive attitudes towards PA, and lower perceived barriers for exercise, can help increase PA in cancer survivors.

A qualitative exploration of exercise motivation among colorectal cancer survivors: an application of the theory of planned behavior

PURPOSE

The purpose of this qualitative study was to use semi-structured interviews and thematic analysis to elicit key influencing factors (i.e., behavioral, normative, and control beliefs) related to physical activity and exercise in colorectal cancer survivors.

METHODS

Colorectal cancer survivors (N = 17) were recruited from exercise programs designed for colorectal cancer survivors at the Yonsei Cancer Center, Seoul, South Korea. A purposive sampling method was used. Interview questions were informed by the theory of planned behavior (TPB). Semi-structured face-to-face interviews were conducted, and open-ended questions addressed the research question. Interviews were transcribed verbatim and analyzed using thematic analysis.

RESULTS

Participants were on average 2.2 years post-treatment. The mean age of the sample was 55.9 years. Key behavioral, normative, and control beliefs emerged in the data. For behavioral beliefs, colorectal cancer survivors believed that exercise would result in physical and psychological improvements, and improve their bowel problems. For normative beliefs, most colorectal cancer survivors wanted their oncologists' approval for participation of exercise. Family members, more specifically the spouse, were also influencing factors for colorectal cancer survivors adopting physical activity. The most frequently mentioned control belief was that supervised exercise with an exercise specialist made exercise participation easier.

CONCLUSIONS AND IMPLICATIONS

Beliefs identified in this study can inform TPB-based physical activity interventions tailored for colorectal cancer survivors. While information alone may not lead to behavior change, integrating these beliefs with other influential factors can potentially enhance intervention efficacy and promote physical activity in this population.

Start With the Body or the Mind? Differential Benefits of Mindfulness and Qigong Practices for Colorectal Cancer Survivors: A Qualitative Study

BACKGROUND

Mindfulness and qigong are 2 distinct forms of mind-body practice that have been well-received by cancer survivors. Although there is evidence supporting the effectiveness of mindfulness or qigong in promoting wellness of cancer survivors, little is known about the differential benefits of these common forms of mind-body practices among survivors.

OBJECTIVE

To compare the potential biopsychosocial-spiritual impacts of mindfulness and Baduanjin (BDJ) qigong on colorectal cancer survivors.

METHODS

Sixty cancer survivors who participated in a mindfulness intervention (n = 38) and BDJ qigong (n = 22) intervention were invited to provide qualitative feedback for their experiences. Content analyses were conducted to identify emerging themes from the data, and χ2 tests were conducted to compare the responses of the mindfulness and BDJ groups in the major categories.

RESULTS

Both practices positively influenced psychosocial wellness. The practice of BDJ qigong led to more prominent improvements in physical well-being, whereas mindfulness worked best in enhancing spiritual growth and intrapersonal connectedness.

CONCLUSIONS

Survivors of colorectal cancer who are looking for ways to enhance their vitality and rejuvenate their physical body may find the practice of BDJ helpful, whereas survivors who are looking for spiritual comfort or growth may consider practicing mindfulness as an entry point toward mind-body unity.

IMPLICATIONS FOR PRACTICE

Mindfulness and BDJ may be helpful for survivors of colorectal cancer to improve their holistic wellness. Oncology nurses can consider prescription of mindfulness and/or BDJ for patients recovering from colorectal cancer.

Relationship between self-efficacy and physical activity among colorectal cancer patients: A cross-sectional study

AIM

To investigate the current status of self-efficacy and physical activity among Chinese colorectal cancer (CRC) patients and explore the relationship between them.

DESIGN

A cross-sectional study.

METHODS

This study was conducted on 282 CRC patients in China. Structured questionnaires were used to collect data on demographic and clinical information, self-efficacy (Exercise Self-Efficacy Scale [ESES]) and physical activity (International Physical Activity Questionnaire-Short Form [IPAQ-SF]).

RESULTS

The median (interquartile range) total self-efficacy score for patients with CRC was 52.78 (42.08-61.11), and the median (interquartile range) total physical activity score was 1776.00 (1142.25-2812.05). Only 28.37% of CRC patients met the guideline recommendations for physical activity. The total self-efficacy score was significantly positively correlated with the total physical activity score (r = 0.123, p = 0.040).

PATIENT OR PUBLIC CONTRIBUTION

CRC patients contributed to the data of this study. Hospital administrators facilitated the implementation of the study.

Effects of supervised high-intensity interval training on motivational outcomes in men with prostate cancer undergoing active surveillance: results from a randomized controlled trial

Background

Understanding the motivational effects of supervised aerobic high-intensity interval training (HIIT) may help men with prostate cancer undergoing active surveillance initiate and maintain exercise behavior, however, few studies have addressed this question. This report explored exercise motivation in men with prostate cancer undergoing active surveillance participating in a randomized exercise trial.

Methods

The Exercise during Active Surveillance for Prostate Cancer (ERASE) trial randomized 52 men with prostate cancer on active surveillance to the HIIT exercise group or the usual care (UC) group. The exercise program was supervised aerobic HIIT conducted three times per week for 12 weeks. The motivation questions were developed using the Theory of Planned Behavior and included motivational constructs, anticipated and experienced outcomes, and barriers to HIIT during active surveillance.

Results

The HIIT group attended 96% of the planned exercise sessions with 100% compliance to the exercise protocol. Motivation outcome data were obtained in 25/26 (96%) participants in the HIIT group and 25/26 (96%) participants in the UC group. At baseline, study participants were generally motivated to perform HIIT. After the intervention, the HIIT group reported that HIIT was even more enjoyable (p < 0.001; d = 1.38), more motivating (p = 0.001; d = 0.89), more controllable (p < 0.001; d = 0.85), and instilled more confidence (p = 0.004; d = 0.66) than they had anticipated. Moreover, compared to UC, HIIT participants reported significantly higher perceived control (p = 0.006; d = 0.68) and a more specific plan (p = 0.032; d = 0.67) for performing HIIT over the next 6 months. No significant differences were found in anticipated versus experienced outcomes. Exercise barriers were minimal, however, the most often reported barriers included pain or soreness (56%), traveling to the fitness center (40%), and being too busy and having limited time (36%).

Conclusion

Men with prostate cancer on active surveillance were largely motivated and expected significant benefits from a supervised HIIT program. Moreover, the men assigned to the HIIT program experienced few barriers and achieved high adherence, which further improved their motivation. Future research is needed to understand long-term exercise motivation and behavior change in this setting.

Barriers and facilitators to exercise among adult cancer survivors in Singapore

PURPOSE

Exercise can help cancer survivors manage sequela, treatment side effects, improve overall quality of life, and is recommended for most. The purpose of this study was to investigate exercise behavior and factors influencing exercise engagement among cancer survivors at the National Cancer Centre, Singapore (NCCS).

METHODS

This cross-sectional study was inclusive of survivors of all cancer types and stages who were at least 21 years of age and had undergone chemotherapy at the NCCS. Surveys were utilized to assess survivor barriers and facilitators to exercise and to retrospectively assess physical activity and exercise behaviors at 4 cancer-related time periods (pre-diagnosis and post-diagnosis before, during, or after chemotherapy).

RESULTS

A total of 102 cancer survivors were enrolled; 60% were diagnosed with stage IV cancer. Predominant cancer types included lower gastrointestinal tract (25.5%) and breast cancer (21.6%). Prior to cancer diagnosis, 90.2% of participants reported aerobic activity satisfying NCCN guidelines. Significant reductions in reported exercise, and physical activity, were observed following cancer diagnosis that persisted during chemotherapy. Key exercise facilitators included the desire to remain healthy (86.3%) and to improve sleep and mental well-being (73.5%). Key barriers included side effects of treatment (52.0%). Only 46.1% of survivors reported receiving exercise guidance from healthcare professionals following diagnosis.

CONCLUSION

Overall, even among this notably active cohort of Singaporean survivors, opportunities for increased exercise engagement throughout the survivorship continuum remain. Increased education regarding the benefits of exercise to survivors as well as guidance regarding exercise modalities including resistance training is greatly needed as well.

Exercise participation, barriers, and preferences in Korean prostate cancer survivors

Objective: To identify patterns of physical activity (PA) participation, exercise preference, and barriers of stage 2-3 prostate cancer survivors across cancer trajectories based on selected demographic and medical variables.Design: The current study is a descriptive cross-sectional study which included data from a total of 111 prostate cancer survivors, at Shinchon Severance Hospital, Seoul, Korea. The survey includes PA levels before and after prostate cancer diagnosis, exercise barriers, and preferences.Results: Moderate- to vigorous-intensity PA levels were significantly lower after cancer diagnosis (vigorous PA:41.9 ± 123.1 min/week vs. 4.6 ± 29.8 min/week, p < 0.001; moderate PA: 159.9 ± 240.0 min/week vs. 56.8 ± 129.7 min/week, p < .001) compared to their PA level before cancer diagnosis. Perceived exercise barriers were distinctly different according to participants' age and time since surgery. The two most prevalent exercise barriers among prostate cancer survivors <65 years were lack of time (28.6%) and poor health (26.5%), whereas the exercise barriers for prostate cancer survivors aged ≥65 years were lack of exercise facilities (21.4%) and lack of exercise information (17.9%). Furthermore, within 6 months after surgery, prostate cancer survivors perceived poor health (29.5%) and pain at the surgery site (29.5%) to be the two most prevalent exercise barriers. 6 months after surgery, prostate cancer survivors perceived lack of time (21.3%) and poor health (14.8%) to be the two most prevalent exercise barriers. Walking, pelvic floor and Kegel exercises were three most preferred exercises among prostate cancer survivors in our study, which uniquely differ according to time since surgery.Conclusion: This study showed significant reduction in PA levels among prostate cancer survivors and their perceived exercise barriers were distinct according to their age and time since surgery. Therefore, PA and exercise recommendation should be specific to their personal characteristics such as age and time since surgery.

Implementation barriers to integrating exercise as medicine in oncology: an ecological scoping review

Purpose

While calls have been made for exercise to become standard practice in oncology, barriers to implementation in real-world settings are not well described. This systematic scoping review aimed to comprehensively describe barriers impeding integration of exercise into routine oncology care within healthcare systems.

Methods

A systematic literature search was conducted across six electronic databases (since 2010) to identify barriers to implementing exercise into real-world settings. An ecological framework was used to classify barriers according to their respective level within the healthcare system.

Results

A total of 1,376 results were retrieved; 50 articles describing implementation barriers in real-world exercise oncology settings were reviewed. Two hundred and forty-three barriers were identified across all levels of the healthcare system. Nearly 40% of barriers existed at the organizational level (n = 93). Lack of structures to support exercise integration and absence of staff/resources to facilitate its delivery were the most common issues reported. Despite the frequency of barriers at the organizational level, organizational stakeholders were largely absent from the research.

Conclusions

Implementing exercise into routine cancer care is hindered by a web of interrelated barriers across all levels of the healthcare system. Organizational barriers are central to most issues. Future work should take an interdisciplinary approach to explore best practices for overcoming implementation barriers, with organizations as a central focus.

Implications for Cancer Survivors

This blueprint of implementation barriers highlights critical issues that need to be overcome to ensure people with cancer have access to the therapeutic benefits of exercise during treatment and beyond.

Correlates of Physical Activity in Colorectal Cancer Patients Based on Health Promotion Model

BACKGROUND

Increasing attention is being given to physical activity in colorectal cancer patients. Some studies have explored a few correlates of physical activity separately. A contemporary study based on the Health Promotion Model may systematically broaden the understanding of physical activity in colorectal cancer patients.

OBJECTIVE

To understand the status of physical activity in Chinese colorectal cancer patients and to explore the correlated factors.

METHODS

A total of 168 adults with colorectal cancer were recruited at 3 tertiary hospitals in China. Participant data were collected on demographics, physical activity, biological factors, anxiety and depression, benefits/barriers to physical activity, self-efficacy, and social support. SAS 8.2 was used for statistical analysis, including descriptive analysis, correlation analysis, single factor analysis, and multiple stepwise regression analysis.

RESULTS

Only 25.60% of colorectal cancer survivors reached the requirements of the Colorectal Cancer Survivorship Care Guidelines. Employment states, number of complications, fatigue, body image, depression, perception of benefits/barriers, and self-efficacy were closely correlated with physical activity in Chinese colorectal cancer patients.

CONCLUSIONS

The physical activity status of patients with colorectal cancer is not optimal. The correlated factors that nurses can take measures to improve are fatigue, body image, depression, perception of benefits/barriers, and self-efficacy, which may improve physical activity in colorectal cancer patients in China. Additional research is needed to determine if improving factors correlated with physical activity will assist with directly increasing physical activity.

IMPLICATIONS FOR PRACTICE

Nurses should evaluate physical activity of colorectal cancer patients timely and play an active role in health promotion programs to improve colorectal cancer patients' physical activity.

Autonomy is not but competence and relatedness are associated with physical activity among colorectal cancer survivors

PURPOSE

The main objective of this study was to use the framework of the self-determination theory, incorporating both internal and external sources of motivation, to identify factors influencing physical activity among colorectal cancer survivors (CRC-S) in Korea.

METHOD

In total, 242 patients at a university-affiliated hospital in Seoul, Korea, responded to a descriptive survey, which comprised questionnaire sets including the Global Physical Activity Questionnaire and the Patient Health Questionnaire. Motivation was then assessed on three scales: the Treatment Self-Regulation (autonomy), Perceived Competence (competence), and the multidimensional Scale of Perceived Social Support (relatedness). Logistic regression analysis was then used to identify factors associated with physical activity.

RESULT

The mean physical activity score was 16.07 metabolic equivalent hours per week, and only 23.3% of patients had an appropriate level of exercise. In the logistic regression analysis, physical activity was associated with competence (odds ratio (OR) = 1.36, 95% confidence interval (CI): 1.06-1.74), relatedness (OR = 1.11, 95% CI: 1.04-1.18), depression (OR = 0.84, 95% CI: 0.75-0.94), and stage I or II disease (OR = 3.33, 95% CI: 1.28-1.86). This study indicated that competence, relatedness, depression, and the disease stage contributed to physical activity among these subjects while autonomy did not.

CONCLUSION

Future interventions to achieve the recommended levels of physical activity among CRC-S could benefit from taking into account the disease stage as well as psychosocial factors including motivation and depression.

The impact of surviving bowel cancer on occupation: A scoping review

Introduction

The number of people surviving bowel cancer is increasing globally, with many of those affected living with long-term psychological and physical sequelae that potentially disrupt occupations.

Method

A scoping review – guided by Arksey and O’Malley’s methodological framework – was conducted to provide an overview of what is known about the impact of having had bowel cancer on occupations, and to reveal the potential role of occupational therapy. A systematic search of four databases and a grey literature repository generated 244 results. Applying inclusion and exclusion criteria, 33 items addressing bowel cancer and occupations were selected and thematically analysed.

Results

Researchers have identified six domains of occupation that are impacted by bowel cancer (social activity, physical activity, sexual activity, employment and role functioning, physical functioning, and self-care) but survivors report a distinct lack of health professional support after completion of medical treatment and being left to devise self-management strategies to accommodate the long-term effects of their cancer.

Conclusion

The sequelae of bowel cancer can have a significant impact on occupational participation. There is scope for increasing and improving occupational therapy input to assist people with cancer-related loss of function to re-engage in valued occupations and improve wellbeing.

Effect of exercise on colorectal cancer prevention and treatment

In recent years, because of improved cancer screening, detection and treatment modalities, a rapid increase in the population of colorectal and other cancer survivors has been observed. The increasing population has justified the requirement of preventive strategies such as lifestyle modifications with regard to obesity, physical activity, diet and smoking. Physical activity may prevent approximately 15% of the colon cancers. Furthermore, several observational studies have demonstrated the efficacy and dose-dependent and anti-cancer effects of exercise on decreasing the mortality and risk of recurrence before and after the colorectal cancer (CRC) diagnosis. However, the required exercise dose, type and intensity are yet unclear. The results of randomised prospective studies are expected to determine the optimal amount, type and intensity of exercise and formulate the most appropriate exercise plan and guidelines, according to the requirements and comorbidities of the patients. In addition, recent studies have focused on the molecular and genetic mechanisms underlying the effect of physical activity on disease outcomes and recurrence rates. This review aimed to investigate the effects of physical activity and the biological basis of these effects in preventing the risk and recurrence of CRC and decreasing the hazards of cancer and cancer treatment.

Gene expression differences among different MSI statuses in colorectal cancer

Colorectal cancer is the third most common cancer in males and second in females. This disease can be caused by genetic and acquired/environmental factors. Microsatellite instability (MSI) is one of the major mechanisms in colorectal cancer. This mechanism is a specific condition of genetic hyper mutability that results from incompetent DNA mismatch repair. MSI has been applied to classify different colorectal cancer subtypes. However, the effects of MSI status on gene expression are largely unknown. In our study, we integrated the gene expression profile and MSI status of all CRC samples from the TCGA database, and then categorized the CRC samples into three subgroups, namely, MSI-stable, MSI-low, and MSI-high, according to the MSI status. We applied a novel computational method based on machine learning and screened the genes specifically expressed for the different colorectal cancer subtypes. The results showed the distinct mechanisms of the different colorectal cancer subtypes with MSI status and provided the genes that may be the optimal standards to further classify the various molecular subtypes of colorectal cancer with distinct MSI status.

Effect of the 6-week home-based exercise program on physical activity level and physical fitness in colorectal cancer survivors: A randomized controlled pilot study

Despite improvement in prognosis of colorectal cancer, colorectal cancer survivors often suffer from adverse effects of cancer treatment, including reduced health-related fitness level. Therefore, this study aimed to examine the feasibility and efficacy of the 6-week home-based exercise program on the level of physical activity and physical fitness in stage II to III colorectal cancer survivors. Seventy-two stage II to III colorectal cancer survivors were randomly assigned to either a home-based exercise (n = 38) or usual care (n = 34) group for 6 weeks. The goal of the home-based exercise program was to increase the level of exercise to 18 metabolic equivalent task hours per week. The primary and the secondary outcomes of this study were physical activity level and physical fitness, respectively. A total of 57 participants (79.2%) completed the trial. Intention-to-treat analysis indicated that moderate physical activity level increased significantly by 269.4 ± 260.6 minutes per week in the exercise group (mean between-group difference, 254.6 minutes; 95% confidence interval, 172.7–434.7; p < 0.001). Physical fitness measured by using the step test (-3.9 vs. 2.6, p = 0.012) and push-up test (3.0 vs. -1.2, p = 0.012) also improved significantly in the exercise group compared to the control group. The 6-week home-based mixed aerobic and resistance exercise program was feasible and effective for increasing physical activity level and physical fitness in stage II to III colorectal cancer survivors.

Associations between physical activity and comorbidities in Korean cancer survivors

PURPOSE

To examine the associations between physical activity, metabolic risk factors, and comorbidities in Korean cancer survivors.

METHODS

We used multiple cross-sectional data sets from the 2007-2013 Korean National Health and Nutrition Examination Surveys (KNHANES) that included 1225 cancer survivors. Physical activity and comorbidities were self-reported. Metabolic risk factors were measured via blood analyses and included fasting glucose, insulin, total cholesterol, triglycerides, and blood pressure.

RESULTS

The sample was 38.4% male with a mean age of 59.9 ± 12.4 years. The most common cancers were stomach (22.5%), cervical (14.6%), breast (14.4%), and colorectal (11.8%). Cancer survivors meeting aerobic physical activity guidelines, compared to those completely inactive, had significantly lower fasting glucose (p = .001), HbA1c (p = .006), and systolic blood pressure (p = .001), and significantly lower risks of hypertension (odds ratio [OR] = 0.55, 95% confidential interval [CI] = 0.32 to 0.93), diabetes (OR = 0.64, 95% CI = 0.43 to 0.95), and arthritis (OR = 0.64, 95% CI = 0.41 to 0.99). Moreover, cancer survivors meeting strength exercise guidelines, compared to those not meeting guidelines, had significantly lower levels of fasting glucose (p = .001), HbA1c (p < .001), and total cholesterol (p = .031), and significantly lower risks of arthritis (OR = 0.42, 95% CI = 0.25 to 0.85) and back pain (OR = 0.50, 95% CI = 0.30 to 0.83).

CONCLUSION

Aerobic physical activity and strength exercise were significantly associated with lower risks of metabolic disturbances and comorbidities in Korean cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Cancer survivors should engage in at least 150 min/week of aerobic exercise and at least 2 days/week of strength exercise to lower their risk of metabolic disturbances and comorbidities.

The association of physical activity and colorectal and breast cancer: The Fifth Korea National Health and Nutrition Examination Survey (2008-2011)

Therapeutic importance of physical activity during and after cancer treatment has been supported. To examine the patterns of physical activity according to the stages of breast and colorectal cancer survivor-ship in Korean, Korean National Health and Nutrition Examination Survey data from 2008 to 2011 were used. International Physical Activity Questionnaire (IPAQ) was utilized to estimate weekly time spent in vigorous- and moderate-intensity physical activity, and walking, and to calculate MET-minute/week. Depending on the survivorship, the subjects were categorized into “never diagnosed with cancer” (group 1), “0–4 yr since cancer diagnosis” (group 2), and “5 or more years since cancer diagnosis” (group 3), separately for colorectal and breast cancer. The associations between physical activity and the cancer survivorship were studied. Following results were obtained: (1) Breast cancer (n=10,167, mean age=48.55±16.27): The mean physical activity levels expressed in MET-minutes/week were 2,064.83, 1748.82, and 1998.36 in groups 1, 2, and 3, respectively. Even though cancer survivors tended to be less active compared to people without cancer, there were no statistically significant difference among the three groups. (2) Colorectal cancer (n=17,270, mean age=48.62): MET-minutes/week was 2064.30, 1084.83, and 709.04 36 in groups 1, 2, and 3, respectively. The differences were significant between group 1 and 2 (F=5.87, P=0.016) and group 1 and 3 (F=28.99, P<0.001). Despite potential therapeutic benefits of physical activity, colorectal cancer survivors were less active than people without cancer in Korea.
