Physical activity behaviour change in black prostate cancer survivors: a qualitative study using the Behaviour Change Wheel.

PURPOSE: Black individuals have a higher cancer burden and face greater obstacles to access cancer care resources when compared to White individuals. Radical prostatectomy is the standard surgical treatment and a common treatment option for prostate cancer; however, when compared to their White counterparts, Black individuals treated for prostate cancer often experience higher treatment-related side effects, resulting in a difficult recovery period. Physical activity is effective in alleviating treatment-related side effects; however, little is known about the barriers and facilitators to physical activity experienced by Black individuals after surgical management of prostate cancer to inform the design of physical activity interventions. METHODS: Twelve Black individuals underwent radical prostatectomy for prostate cancer participated in a focus group study. We used the Behaviour Change Wheel, which incorporates Capability, Opportunity, Behaviour (COM-B) model and the complementary Theoretical Domains Framework (TDF), as our guiding theoretical framework. Data was analyzed using deductive qualitative analysis. RESULTS: Facilitators and barriers were identified for all components of the Behaviour Change Wheel. Capability appeared to be a central factor to how participants described their physical activity engagement. Opportunity and motivation were described as both barriers and facilitators for behaviour change when occurring in isolation; however, when co-occurring with the presence of capability, they were described as facilitators that influence participants' physical activity engagement. CONCLUSIONS: Our results demonstrate barriers and facilitators that are recognized among Black individuals who have undergone radical prostatectomy for prostate cancer. The design of a physical activity intervention needs to consider the physical and psychological capabilities as the fundamental basis with the additional support of physical activity opportunity and motivation. IMPLICATIONS FOR CANCER SURVIVORS: Intersectionality across capability, opportunity, and motivation is essential to intervention design and development to increase physical activity in Black individuals surgically treated for prostate cancer.

Exploring physical activity experiences, barriers, and facilitators among individuals of South Asian heritage living with and beyond cancer.

OBJECTIVES: The purpose of this study was to understand the physical activity (PA) experiences, as well as preferences, barriers, and facilitators to exercise, among individuals of South Asian heritage diagnosed with cancer. DESIGN: A qualitative descriptive design was used. Individuals of South Asian heritage were recruited via a mix of convenience sampling and purposive sampling, with outreach via radio, posters in community settings, and from outreach to participants in current exercise oncology studies. Inclusion criteria included being over the age of 18; diagnosed with any cancer type and stage; pre, during, or post-treatment; able to speak English, Hindi, or Punjabi; and self-identified as South Asian. Data for this study was collected via semi-structured interviews conducted in the participants language of choice. Interviews were transcribed verbatim in the original language and then analyzed using conventional content analysis. For non-English interviews, the codes created through analysis were subsequently translated into English, and back-translated into the original language, to ensure accuracy. These codes were then organized into themes and categories. RESULTS: Eight participants were recruited, with 5 interviews conducted in Punjabi and 3 interviews in English. The three themes that were created from the participant interviews include: (1) Culture, (2) Informational Needs, and (3) The Nature of Exercise Oncology Interventions. Within these themes, categories included barriers and facilitators to PA, as well as PA needs. CONCLUSION: Participants' perspectives provided insights into the PA experiences, barriers, facilitators, and needs of people of South Asian heritage living with and beyond cancer. These results can be used to inform the tailoring of exercise oncology resources to better support physical activity and exercise for this population.

The role of exercise for pain management in adults living with and beyond cancer: a systematic review and meta-analysis.

BACKGROUND: Pain is a common side effect of cancer or cancer treatment that negatively impacts biopsychosocial wellbeing and quality of life. Exercise is a potential intervention to manage pain that is safe and has multiple benefits. The objective was to determine the role of exercise in cancer pain management. METHODS: We completed a systematic review and meta-analysis of exercise interventions in adults with any type or stage of cancer by searching Ovid MEDLINE®, Embase, APA PsycInfo, the Cochrane Central Register of Controlled Trials, CINAHL, and SPORTDiscus. We included experimental and quasi-experimental designs where pain was measured as an outcome. Data synthesis included narrative and tabular summary. A meta-analysis was performed on studies powered to detect the effect of exercise on pain. Study quality was evaluated using the Cochrane risk of bias tool and certainty of evidence was evaluated using the GRADE tool. RESULTS: Seventy-six studies were included. Studies were predominantly conducted in breast cancer and exercise usually included a combination of aerobic and strength training. Ten studies were included in the meta-analysis demonstrating a significant effect for exercise in decreasing pain (estimated average standard mean difference (SMD) was g = - 0.73 (95% CI: - 1.16 to - 0.30)); however, the overall effect prediction interval was large. Overall risk of bias for most studies was rated as some concerns and the grading of evidence certainty was low. CONCLUSION: There are limitations in the evidence for exercise to manage cancer-related pain. Further research is needed to understand the role of exercise in a multimodal pain management strategy.

Tai Chi for cancer survivors: A systematic review toward consensus-based guidelines.

To manage acute, long-term, and late effects of cancer, current guidelines recommend moderate-to-vigorous intensity aerobic and resistance exercise. Unfortunately, not all cancer survivors are able or willing to perform higher intensity exercise during difficult cancer treatments or because of other existing health conditions. Tai Chi is an equipment-free, multicomponent mind-body exercise performed at light-to-moderate intensity that may provide a more feasible alternative to traditional exercise programs for some cancer survivors. This systematic review evaluated the therapeutic efficacy of Tai Chi across the cancer care continuum. We searched MEDLINE/PubMed, Embase, SCOPUS, and CINAHL databases for interventional studies from inception to 18 September 2020. Controlled trials of the effects of Tai Chi training on patient-reported and objectively measured outcomes in cancer survivors were included. Study quality was determined by the RoB 2 tool, and effect estimates were evaluated using the Best Evidence Synthesis approach. Twenty-six reports from 14 trials (one non-randomized controlled trial) conducted during (n = 5) and after treatment (after surgery: n = 2; after other treatments: n = 7) were included. Low-level evidence emerged to support the benefits of 40-60 min of thrice-weekly supervised Tai Chi for 8-12 weeks to improve fatigue and sleep quality in cancer survivors. These findings need to be confirmed in larger trials and tested for scaling-up potential. Insufficient evidence was available to evaluate the effects of Tai Chi on other cancer-related outcomes. Future research should examine whether Tai Chi training can improve a broader range of cancer outcomes including during the pre-treatment and end of life phases.

Occupational Physical Activity and Lung Cancer Risk: A Systematic Review and Meta-Analysis.

OBJECTIVE: To deliver a systematic review of the literature synthesizing data on the association of occupational physical activity with lung cancer risk in observational studies. DESIGN: Systematic review with meta-analysis. DATA SOURCE: A literature search was performed in the electronic databases of PubMed/Medline and Embase. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We screened peer-reviewed articles from prospective cohort and case-control studies assessing the association of occupational physical activity with lung cancer risk. A sex-specific meta-analysis assessed the association of high (compared to low/sedentary) level occupational physical activity with lung cancer risk, estimating the relative risk (RR) and odds ratio (OR) with a 95% confidence interval (CI). RESULTS: The systematic search identified 2065 articles, among which, eight journal articles met the inclusion criteria. The meta-analysis adjusted for age, smoking status and/or intensity, with a pooled sample size of 532,282 participants (men: 219,410; women: 312,872). A random-effect model of four prospective and four case-control studies indicated that men who engage in high-level occupational physical activity had a 15% higher risk (OR 1.15, 95% CI 1.04-1.28) of lung cancer than those engaging in low/sedentary-level occupational physical activity. There was no association observed among women (OR = 1.01, 95% CI 0.77-1.34) based on three available studies (prospective cohort: n = 2; case-control: n = 1). CONCLUSIONS: Findings from the review suggest a higher risk of lung cancer among men reporting high-level occupational physical activity. Further prospective studies incorporating rigorous measures of domain-specific physical activity, detailed smoking status and intensity, and other occupational exposures are needed to elucidate this association.

Associations in physical activity and sedentary behaviour among the immigrant and non-immigrant US population.

BACKGROUND: Immigrants are at a higher risk of poor mental and physical health. Regular participation in physical activity (PA) and low levels of sedentary time are beneficial for both these aspects of health. The aim was to investigate levels and trends in domain-specific PA and sedentary behaviour in the US. immigrant compared with non-immigrant populations. METHODS: From the 2007-2016 National Health and Nutrition Examination Survey (NHANES), a total of 25 142 adults (≥18 years) were included in this analysis. PA and sedentary behaviour time were assessed by a questionnaire. RESULTS: Transit-related PA showed downward linear trends in young immigrant adults (ptrend=0.006) and middle-aged non-immigrant adults (ptrend=0.009). We found significant upward linear trends in sedentary behaviour for both immigrants and non-immigrants across all age groups. For sitting watching TV or videos ≥2 hours/day, there was a downward linear trend in young immigrant adults (ptrend=0.009). For computer use ≥1 hours/day, an upward linear trend in older non-immigrants was found (ptrend=0.024). Young immigrants spent 37.5 (95% CI -55.4 to -19.6) min less than non-immigrants on recreational PA per week. Also, older immigrants spent 23.5 (95% CI 1.5 to 45.6) and 22.5 (95% CI 5.9 to 39.0) min/week more than non-immigrants on recreational PA and transit-related PA, respectively. Last, young and middle-aged immigrants spent 37.6 (95% CI -68.2 to -7.0) and 37.6 (95% CI -99.7 to -9.7) min/day less than non-immigrants on sedentary behaviour, respectively. CONCLUSION: Overall, levels of recreational PA were stable, yet the transit-related PA declined coupled with an increase in sedentary behaviour. US. immigrants exhibit higher levels of transit-PA, lower levels of leisure-time PA and lower levels of sedentary behaviour, in some age groups.
