Correlates of physical activity among older breast cancer survivors: Findings from the Women's Health Initiative LILAC study

Physical Activity Patterns According to Demographic, Social, and Clinical Correlates Among Breast Cancer Survivors

INTRODUCTION

Moderate to vigorous physical activity (MVPA) after breast cancer diagnosis is associated with improved survivorship. However, differences in MVPA by race among breast cancer survivors are not well described in population-based studies.

METHODS

We analyzed data from Carolina Breast Cancer Study Phase 3 (n = 2994, 50% Black) participants to evaluate the trajectory of MVPA from pre-diagnosis to 18-month post-diagnosis. Participants self-reported MVPA at baseline (pre-diagnosis) and 6- and 18-month post-diagnosis and were classified as having any MVPA (> 0 min/week) or no MVPA. Associations between MVPA and demographic, social, and clinical variables were estimated using multivariable logistic regression.

RESULTS

At baseline, 84.0% of participants reported any MVPA pre-diagnosis, which dropped to 55.4% at 6-month post-diagnosis, then rebounded to 85.1% by 18-month post-diagnosis. Among those who had no MVPA pre-diagnosis, 32.5% and 71.0% became active at 6- and 18-month post-diagnosis, respectively. Higher income [adjusted odds ratio (aOR) = 1.33, 95% confidence interval (CI) (1.02, 1.74) > $30K vs. < 15K], lower body mass index [aOR = 1.30, 95% CI (1.00, 1.73) < 25 vs. > 30], low area deprivation [aOR = 1.35, 95% CI (1.08, 1.67) vs. high], high area assets [aOR = 1.54, 95% CI (1.23, 1.93) vs. low], and stage I breast cancer [aOR = 1.72, 95% CI (1.22, 2.43) vs. 3 or 4] were associated with any MVPA at 18-month post-diagnosis.

CONCLUSION

We identified several demographic and social correlates of any MVPA at 18-month post-diagnosis, and together with established clinical correlates (such as late disease), these factors may contribute to breast cancer disparities.

Physical activity and cognition: longitudinal findings from the Thinking and Living with Cancer Study

BACKGROUND

Physical activity can improve cognition; however, little is known regarding the relationships between longitudinal objectively measured physical activity, cognition, and inflammation in older breast cancer survivors.

METHODS

Older (aged 60 years and older) breast cancer survivors (n = 216) and frequency-matched noncancer control participants (n = 216) were assessed at baseline (presystemic therapy for survivors) and annually for up to 5 years. Assessments included hip-worn actigraphs worn for 7 days, neuropsychological tests, the Functional Assessment of Cancer Therapy-Cognitive Function perceived cognitive impairment subscale, and circulating levels of C-reactive protein and interleukin-6. Data were analyzed using linear mixed-effect, random-effect contemporaneous fluctuation, and multilevel mediation models, considering covariates; a P value less than .05 (2-sided) was considered statistically significant.

RESULTS

Survivors had fewer minutes of moderate-to-vigorous physical activity than controls at 36-, 48-, and 60-month time points (P < .03). Fewer survivors met aerobic physical activity guidelines at 36 months than control participants (17.7% vs 33.0%, P = .030). When guidelines were met (vs not), Functional Assessment of Cancer Therapy-Cognitive Function perceived cognitive impairment scores were 2.1 (1.0) (P = .034) points higher. Higher moderate-to-vigorous physical activity and meeting aerobic guidelines were not related to objective neuropsychological performance. Moderate-to-vigorous physical activity was inversely associated with C-reactive protein and interleukin-6 (P < .001), but inflammation did not mediate physical activity effects on perceived cognition.

CONCLUSIONS

Older breast cancer survivors were less physically active than older noncancer controls, especially farther from baseline. Meeting aerobic guidelines was associated with better perceived cognition in survivors. Survivorship care should consider physical activity monitoring and referral to rehabilitation and supervised exercise programs to promote physical activity and improve recovery in older survivors.

Physical Activity Among Utah Cancer Survivors: Analysis From a Population-Based Statewide Survey

BACKGROUND

Regular physical activity improves cancer survivors' health-related quality of life and physical function. We estimated the proportion of Utah cancer survivors meeting U.S. Department of Health and Human Services guidelines for weekly physical activity (aerobic plus strength exercise) and identify sociodemographic, cancer, and health-related factors associated with meeting guidelines.

METHODS

Survivors randomly sampled from Utah Cancer Registry records were surveyed from 2018 to 2022 to ascertain physical activity. We calculated the percent of survivors meeting guidelines and conducted logistic regression to assess predictors of meeting guidelines. Analyses were weighted to account for complex survey sample design and nonresponse and age adjusted.

RESULTS

Among Utah cancer survivors, 20.7% (95% CI, 18.5%-23.2%) met guidelines for both aerobic activity and strength exercise. 22.4% reported no aerobic exercise in a typical week, and 59.4% reported no strength exercise. Survivors 75 or older were less likely to meet physical activity guidelines than those under 55 (adjusted odds ratio: 0.40; 95% CI, 0.25-0.65). Survivors with a bachelor's degree or higher were more likely to meet physical activity guidelines than those without a college degree. Individuals with poorer overall health were less likely to report sufficient physical activity. Individuals treated with both chemotherapy and radiation had decreased odds of meeting guidelines compared to no treatment (adjusted odds ratio: 0.54; 95% CI, 0.29-0.99).

CONCLUSIONS

Most Utah cancer survivors, and particularly those who received multiple modes of adjuvant treatment, are not participating in sufficient physical activity to improve longevity and quality of life after cancer.

Determinants and factors of physical activity and sedentary behaviors among post-treatment breast, colorectal, lung, and prostate cancer survivors living in France: Results from the DEFACTO study first phase

OBJECTIVE

This study aimed to investigate the facilitators and barriers to adopting an active lifestyle among post-treatment cancer survivors in France.

METHODS

Breast, colorectal, lung, and prostate cancer survivors were recruited. Participants completed a questionnaire covering sociodemographic and clinical factors, physical activity (PA) experiences, variables from the Transtheoretical model, types of motivation, knowledge of PA benefits, barriers to PA, and quality of life. We categorized participants into 4 profiles combining PA level and sedentary behaviors.

RESULTS

One hundred and seventy-five participants were included. Ordinal logistic regression revealed that the active lifestyle of cancer survivors is influenced by their professional situation (OR, 3.99; 95%CI, 1.76-9.10 and OR, 3.14; 95%CI, 1.45-6.77), the use of self-liberation (OR, 0.41; 95%CI, 0.20-0.82), helping relationships processes of change (OR, 2.45; 95%CI, 1.20-5.00), and quality of life (OR, 1.11; 95%CI, 1.04-1.18).

CONCLUSIONS

Identifying the factors associated with PA and sedentary behavior among cancer survivors in France will facilitate the adaptation of programs according to a whole-person approach. Semi-structured interviews will further enhance insights in this mixed-methods study.

PRACTICE IMPLICATIONS

Interventions aimed at promoting an active lifestyle among cancer survivors should be customized based on professional situation, the utilization of experiential behavior change processes, and perceived quality of life.

Reasons for declining participation in an exercise-based trial among older women with breast cancer receiving systemic anti-cancer treatment - a qualitative interview study

BACKGROUND

Breast cancer is the most frequently diagnosed cancer in the world. Exercise is widely recommended for patients with breast cancer during and after treatment. However, there is a lack of studies investigating barriers related to participation in real-world exercise-based trials for older patients with breast cancer.

OBJECTIVE

To explore reasons for declining participation in an exercise-based trial among older patients with breast cancer during (neo)adjuvant or palliative systemic treatment.

METHODS

A qualitative study using semi-structured interviews. Patients who declined participation in an exercise-based trial (N = 50) were invited to participate. Semi-structured interviews were conducted with 15 participants. Interviews were audio-recorded, transcribed verbatim and analyzed using thematic analysis.

RESULTS

Identified main themes: 1) Lack of energy and resources, including two subthemes: 1a) Overwhelmed both mentally and physically, and 1b) The program is too comprehensive; 2) Uncertainty about reactions to chemotherapy; 3) The hospital is not the optimal exercise setting, including two subthemes: 3a) Transportation and time consumption, and 3b) No desire to spend additional time at the hospital; and 4) Staying active in my own way, including two subthemes: 4a) Motivation to exercise, and 4b) Preferences for exercise activities.

CONCLUSION

Many barriers were identified, including time of recruitment, information overload, symptoms and side effects, and the hospital as the exercise setting due to practical challenges and negative feelings. Participants were motivated to exercise from knowledge about the benefits of exercising. Furthermore, they preferred activities that they were already involved in or had experience with.

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.

Prevalence of loneliness and associations with health behaviours and body mass index in 5835 people living with and beyond cancer: a cross-sectional study

BACKGROUND

A cancer diagnosis and its treatment may be an especially isolating experience. Despite evidence that positive health behaviours can improve outcomes for people living with and beyond cancer (LWBC), no studies have examined associations between loneliness and different health behaviours in this population. This study aimed to describe the prevalence of loneliness in a large sample of UK adults LWBC and to explore whether loneliness was associated with multiple health behaviours.

METHODS

Participants were adults (aged ≥ 18 years) diagnosed with breast, prostate or colorectal cancer who completed the Health and Lifestyle After Cancer Survey. Loneliness was reported using the UCLA loneliness score, dichotomised into higher (≥ 6) versus lower (< 6) loneliness. Engagement in moderate-to-vigorous physical activity, dietary intake, smoking status, alcohol use, and self-reported height and weight were recorded. Behaviours were coded to reflect meeting or not meeting the World Cancer Research Fund recommendations for people LWBC. Logistic regression analyses explored associations between loneliness and health behaviours. Covariates were age, sex, ethnicity, education, marital status, living situation, cancer type, spread and treatment, time since treatment, time since diagnosis and number of comorbid conditions. Multiple imputation was used to account for missing data.

RESULTS

5835 participants, mean age 67.4 (standard deviation = 11.8) years, completed the survey. 56% were female (n = 3266) and 44% (n = 2553) male, and 48% (n = 2786) were living with or beyond breast cancer, 32% (n = 1839) prostate, and 21% (n = 1210) colorectal. Of 5485 who completed the loneliness scale, 81% (n = 4423) of participants reported lower and 19% (n = 1035) higher loneliness. After adjustment for confounders, those reporting higher levels of loneliness had lower odds of meeting the WCRF recommendations for moderate-to-vigorous physical activity (Odds Ratio [OR] 0.78, 95% Confidence Internal [CI], 0.67, 0.97, p =.028), fruit and vegetable intake (OR 0.81, CI 0.67, 1.00, p =.046), and smoking (OR 0.62, 0.46, 0.84, p =.003). No association was observed between loneliness and the other dietary behaviours, alcohol, or body mass index.

CONCLUSIONS

Loneliness is relatively common in people LWBC and may represent an unmet need. People LWBC who experience higher levels of loneliness may need additional support to improve their health behaviours.

Ballet after breast cancer: investigating the feasibility and acceptability of a novel 16-week classical ballet intervention for breast cancer survivors

Purpose

The “Ballet after breast cancer” study sought to investigate the feasibility and acceptability of a 16-week classical ballet intervention for breast cancer survivors, delivered face-to-face and/or online.

Methods

Breast cancer survivors were recruited to take part in 2 × 1-h ballet classes per week for 16 weeks. Primary outcomes of feasibility and acceptability were assessed according to rates of enrolment and attendance and participant feedback via questionnaire. Secondary outcomes included quality of life (QOL), upper-body disability, shoulder range of motion (ROM), muscular strength, aerobic capacity, and physical activity levels. Associations between rate of attendance and changes in secondary measures were explored.

Results

Thirty-one participants (62% of eligible individuals) enrolled in the program. Twenty-nine women commenced the intervention [53.3 ± 10.8 years (Mean ± SD)], attending 77.6% [67.6, 87.5] (Mean [95% CI]) of sessions. Based on these rates of enrolment and attendance, and participant feedback, the program was deemed feasible and acceptable to participants. Significant improvements in shoulder ROM and reductions in sedentary behaviour were achieved. Participants also reported improvements in physical capacity and psychological, social, and cognitive wellbeing.

Conclusions

The “Ballet after breast cancer” program, delivered face-to-face and/or online, was feasible and acceptable to breast cancer survivors. Improvements in shoulder ROM achieved doing ballet were pertinent given the adverse effects of upper-body morbidity on breast cancer survivor QOL. Improvements in physical activity behaviour and perceived benefits to wellbeing also support the use of ballet to mitigate QOL impairment after treatment.

Implications for cancer survivors

The physical demands and the fun, creative, and social characteristics of ballet promote improvement across multiple domains of health and wellbeing. Ballet shows promise as an activity to improve QOL and increase long-term engagement in health-promoting physical activity after breast cancer.
