Promoting Team-Based Exercise Among African American Breast Cancer Survivors

Barriers and facilitators for weight management interventions in breast cancer patients: a systematic review of qualitative studies

INTRODUCTION

This systematic review and meta-synthesis of qualitative studies provides an overview of barriers and facilitators that breast cancer patients experience in weight management interventions.

METHODS

We included qualitative studies describing barriers and facilitators for weight management interventions as experienced by adult breast cancer patients after the completion of initial treatment . The data was extracted and using thematic analysis.

RESULTS

After analysis, eleven themes were determined. Six of those themes could be linked to the Attitude, Social Influence and self Efficacy (ASE)-model. Physical and mental benefits, anticipated regret and a lack of motivation were linked to attitude. Integrating a weight management programme in daily life, stigma and fears were linked to self-efficacy. With regard to the social influence determinant, encouragement and discouragement by family members were developed as a theme. Four additional themes were conducted related to weight management behaviour; external barriers, economic barriers, cultural barriers and physical barriers. In addition, integrating weight management in cancer care was described as a separate theme.

CONCLUSIONS

Several disease specific issues, including feeling stigmatized after cancer treatment and treatment-related side effects and peer-support should be given specific attention to maximize adherence of weight management programmes.

Polymorphisms in Cytokine Receptor and Regulator Genes are Associated with Levels of Exercise in Women Prior to Breast Cancer Surgery

Background: Little is known about the genetic characteristics associated with exercise in women undergoing breast cancer surgery. Purpose: In a sample of women who were evaluated prior to breast cancer surgery (n = 310), we evaluated for differences in demographic and clinical characteristics between patients who did and did not exercise on a regular basis and evaluated for associations between polymorphisms in genes for pro- and anti-inflammatory cytokines, their receptors, and their transcriptional regulators. Methods: Patients completed an investigator-developed exercise questionnaire. Based on the recommended level of exercise (≥150 minutes/week), survivors were classified into no exercise (NoEx), less exercise (LessEx), or recommended exercise (RecEx) groups. Candidate gene analyses were done to identify relationships between polymorphisms and exercise group membership (i.e., NoEx vs. RecEx). Only 23.5% of the total sample met the recommendations for regular exercise. Results: Compared to the RecEx group (n = 78), patients in the NoEx group (n = 120) had less education; were less likely to report being White or Asia/Pacific Islander; more likely to report a lower household income; had a higher body mass index (BMI), had a poorer functional status; had a higher comorbidity burden; were more likely to self-report high blood pressure; and were more likely to have received neoadjuvant chemotherapy. Polymorphisms in IFNGR1 and NFKB1 were associated with membership in the NoEx group. Conclusions: While they warrant replication, our findings suggest that variations in cytokine-related genes may play a role in exercise behavior, and that clinicians need to assess for barriers to regular exercise and educate patients on its benefits.

Cross-sector co-creation of a community-based physical activity program for breast cancer survivors in Colombia

Benefits of physical activity (PA) in breast cancer survivors (BCS) are well established. However, programs to promote PA among BCS tailored to real-world contexts within low- to middle-income countries are limited. Cross-sector co-creation can be key to effective and scalable programs for BCS in these countries. This study aimed to evaluate the networking process to engage multisector stakeholders in the co-creation of a PA program for Colombian BCS called My Body. We employed a mixed-methods design including semistructured interviews, workshops and a social network analysis of centrality measures to assess stakeholders' engagement, resources and skills enabling the collaborative work, challenges, outcomes and lessons learned. The descriptive analysis and the centrality measures of the network revealed that 19 cross-sector stakeholders engaged in the My Body collaborative network. Through ongoing communication and cooperation, My Body built relationships between the academic lead institutions (local and international), and local and national public, private and academic institutions working in public health, sports and recreation, social sciences and engineering fields. The outcomes included the co-creation of the community-based PA program for BCS, its implementation through cross-sector synergies, increased relationships and communications among stakeholders, and successful dissemination of evidence and project results to the collaboration partners and other relevant stakeholders and community members. The mixed-methods assessment enabled understanding of ways to advance cross-sector co-creation of health promotion programs. The findings can help to enable continued development of sustainable cross-sector co-creation processes aimed at advancing PA promotion.

Innovative participatory evaluation methodologies to assess and sustain multilevel impacts of two community-based physical activity programs for women in Colombia

Background

Community-based physical activity (PA) programs are appealing to women in Latin America and show potential for improving women’s health. This study aimed to engage healthy middle-aged women, breast cancer survivors and local stakeholders participating in two publicly funded community-based PA programs in Bogotá, Colombia (Recreovía and My Body) to assess and visually map the perceived barriers, facilitators, and outcomes to promote programs’ improvement, scaling and sustainability.

Methods

We used two participatory action research methods, the 1) Our Voice citizen science method to capture data and drive local change in built and social environmental facilitators and barriers that influence women’s engagement in community-based PA; and 2) Ripple Effects Mapping to visually map the intended and unintended outcomes of PA programs. We used thematic analysis to classify the results at the individual, social, and community levels.

Results

The stakeholders engaged in the participatory evaluation included cross-sector actors from the programs (N = 6) and program users (total N = 34) from the two programs (Recreovía N = 16; My Body N = 18). Program users were women with a mean age of 55.7 years (SD = 8.03), 65% lived in low-income neighborhoods. They identified infrastructure as the main feature affecting PA, having both positive (e.g., appropriate facilities) and negative (e.g., poorly built areas for PA) effects. Regarding program improvements, stakeholders advocated for parks’ cleaning, safety, and appropriate use. The most highlighted outcomes were the expansion and strengthening of social bonds and the engagement in collective wellbeing, which leveraged some participants’ leadership skills for PA promotion strategies in their community. The facilitated dialogue among program users and stakeholders fostered the sustainability and expansion of the community-based PA programs, even during the COVID-19 pandemic.

Conclusions

The implementation of both participatory methodologies provided a multidimensional understanding of the programs’ impacts and multisectoral dialogues that fostered efforts to sustain the community-based PA programs.

Physical activity motives, barriers, and preferences in people with obesity: A systematic review

Background

Although the benefits of physical activity (PA) are well known, physical inactivity is highly prevalent among people with obesity. The objective of this systematic review was to i) appraise knowledge on PA motives, barriers, and preferences in individuals with obesity, and ii) quantify the most frequently reported PA motives, barriers and preferences in this population.

Methods

Six databases (Pubmed, CINAHL, Psyarticle, SportDiscus, Web of science and Proquest) were searched by independent reviewers to identify relevant quantitative or qualitative articles reporting PA motives, barriers or preferences in adults with body mass index ≥ 30 kg/m² (last searched in June 2020). Risk of bias for each study was assessed by two independent reviewers with the Mixed Methods Appraisal Tool (MMAT).

Results

From 5,899 papers identified, a total of 27 studies, 14 quantitative, 10 qualitative and 3 mixed studies were included. About 30% of studies have a MMAT score below 50% (k = 8). The three most reported PA motives in people with obesity were weight management, energy/physical fitness, and social support. The three most common PA barriers were lack of self-discipline/motivation, pain or physical discomfort, and lack of time. Based on the only 4 studies available, walking seems to be the preferred mode of PA in people with obesity.

Conclusions

Weight management, lack of motivation and pain are key PA motives and barriers in people with obesity, and should be addressed in future interventions to facilitate PA initiation and maintenance. Further research is needed to investigate the PA preferences of people with obesity.

Harnessing Nutrition and Physical Activity for Breast Cancer Prevention and Control to Reduce Racial/Ethnic Cancer Health Disparities

There are well-known racial/ethnic disparities in the prevalence of obesity and physical inactivity, as well as breast cancer risk and survival. However, most of the current scientific evidence that serves as a foundation for nutrition and physical activity guidelines is based on studies conducted in predominantly non-Hispanic White populations. Similarly, exercise, diet, or lifestyle intervention trials for breast cancer prevention and survivorship are scarce in racial/ethnic minority populations. We review the current evidence for racial/ethnic disparities in obesity and breast cancer risk and survival (we are focusing on obesity, because this is considered an ASCO priority, and studies conducted in the United States), discuss the evolution of nutrition/physical activity guidelines for cancer prevention and control, and provide an overview of lifestyle interventions, including barriers and facilitators in implementation and dissemination science among minority populations underrepresented in research. There is a critical need to include racially/ethnically diverse populations in cancer prevention and control research or to specifically target minority populations in which disparities are known to exist to achieve much needed health equity.

Hispanic ethnicity as a moderator of the effects of aerobic and resistance exercise on physical fitness and quality-of-life in breast cancer survivors

BACKGROUND

Exercise can profoundly affect physical fitness and quality of life in breast cancer survivors; however, few studies have focused on minorities. This secondary analysis examines Hispanic ethnicity as a moderator of the effects of a 16-week aerobic and resistance exercise intervention on physical fitness and quality of life in breast cancer survivors.

METHODS

Eligible breast cancer survivors (n = 100) were randomized to exercise (n = 50) or usual care (n = 50). The exercise intervention consisted of supervised moderate-vigorous aerobic and resistance exercise thrice weekly for 16 weeks. Physical fitness and quality of life were measured at baseline, post-intervention, and 28-week follow-up (exercise only). Linear mixed-models adjusted for baseline value of the outcome, age, disease stage, adjuvant treatment, and recent physical activity were used to evaluate effect modification by ethnicity.

RESULTS

The study sample included 57% Hispanic and 43% non-Hispanic breast cancer survivors. Hispanic breast cancer survivors were younger, less fit, and diagnosed with more advanced cancers compared with non-Hispanic breast cancer survivors (p < 0.001). Ethnicity was found to moderate the effects of exercise training on all physical fitness and quality-of-life measures including VO_2max (8.4 mL/kg/min; 95% confidence interval (95% CI) 3.2 to 13.4), physical well-being (12.3; 95% CI 4.2 to 18.4), and emotional well-being (11.4; 95% CI 5.9 to 15.5). In all cases, Hispanics experienced larger benefits than non-Hispanics.

CONCLUSIONS

Hispanic breast cancer survivors have poorer cardiorespiratory fitness, muscle strength, and quality-of-life and therefore may derive larger benefits from exercise than non-Hispanic breast cancer survivors. Clinical exercise interventions may attenuate existing health disparities among minority breast cancer survivors.

IMPLICATION OF CANCER SURVIVORS

Here we report psychosocial and fitness-related disparities among Hispanic breast cancer survivors when compared with their non-Hispanic counterparts. Our exercise intervention highlights the importance of exercise for minority cancer survivors and the need for distinct, culturally tailored exercise intervention approaches to reduce psychosocial and fitness-related disparities among this understudied population of cancer survivors.

Team triathlon effects on physiological, psychological, and immunological measures in women breast cancer survivors

PURPOSE

Exercise after breast cancer diagnosis and treatment improves cancer-related outcomes, although the mechanisms involved are not clear. This study evaluated the impact of exercise on body composition, strength, endurance, quality of life (QOL), fatigue, and endocrine and inflammatory biomarkers in breast cancer survivors participating in a highly monitored, clinically supervised, moderate-intensity exercise program. The association of hormonal and inflammatory biomarkers with the observed physiological changes was assessed.

METHODS

Female breast cancer survivors (BCS; n = 46) who engaged in a goal-oriented 14-week triathlon exercise training program were compared to an untrained control group of female BCS (n = 16). Psychosocial metrics, QOL, cancer-related fatigue, and exercise self-efficacy were evaluated via pre- and post-exercise intervention questionnaires. Serum estradiol and inflammatory biomarkers (C-reactive protein (CRP), sTNFR1a, estradiol, leptin, and adiponectin) were measured prior to the exercise training program start and after the completion of the goal triathlon.

RESULTS

After exercise training, the exercise group had lower BMI and arm circumferences. Greater positive change was noted in the trained group for QOL, fatigue, and self-efficacy questionnaires. Functional endurance improved in the trained but not the control group. Knee and elbow strength were not different between the groups, except that knee flexion at 180 degrees∙sec^-1 was higher in trained. The only significantly different biomarker was adiponectin, which decreased in the trained group.

CONCLUSIONS

Group triathlon exercise training may be beneficial to BCS by significantly improving their psychosocial measures, functional endurance, and BMI.

The experience of cancer-related fatigue, exercise and exercise adherence among women breast cancer survivors: Insights from focus group interviews

AIMS AND OBJECTIVES

To identify the experience of breast cancer survivors regarding cancer-related fatigue, exercise and exercise adherence.

BACKGROUND

Cancer-related fatigue is a common symptom among cancer survivors that limits quality of life. Despite exercise being recommended as a viable solution to manage cancer-related fatigue, relatively few research studies on the experience of cancer-related fatigue and exercise adherence have been conducted.

DESIGN

This was a qualitative study to identify breast cancer survivors' experience of cancer-related fatigue, exercise and exercise adherence. This paper adhered to the COREQ checklist in reporting.

METHODS

Four focus group interviews were conducted with 16 breast cancer survivors who had fatigue score of 4 out of 10 (moderate fatigue) or greater. Ethical approval was obtained and participants met for focus group interview discussion. The interview guide included questions on cancer-related fatigue, barriers and facilitators of exercising, strategies for exercise adherence and suggestions for a supportive programme.

RESULTS

Four themes were identified through thematic analysis: (a) The insidious and overpowering nature of cancer-related fatigue; (b) exercising when experiencing fatigue surrounded by prevailing myths; (c) multiple barriers to exercise; and (d) facilitative factors to continue exercising despite fatigue.

CONCLUSIONS

Participants' experience of moderate or greater cancer-related fatigue prevented them from exercising, despite knowing its importance, and limited them to passive activities. Misconceptions that exercise is associated with lymphedema and risk of recurrence, poor psychosocial self-image and lack of clear knowledge and exercise programmes for cancer survivors further limited adherence to exercise. In contrast, finding comfort and strength through exercising and interacting with other breast cancer survivors were facilitative factors.

RELEVANCE TO CLINICAL PRACTICE

The insights shared by breast cancer survivors experiencing cancer-related fatigue can contribute to developing an exercise adherence programme as a way to manage and alleviate fatigue and establish healthy survivorship care.

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.
