Adherence to multiple health behaviours in cancer survivors: a systematic review and meta-analysis

Cross-sectional and longitudinal associations of adherence to WCRF/AICR cancer prevention recommendations with health-related quality of life in breast cancer survivors. Health-EpiGEICAM study

OBJECTIVES

Adherence to healthy lifestyle recommendations has been reported to improve health-related quality of life (HRQL) in breast cancer (BC) patients, but the influence of long-term behavioral changes remains unknown. We evaluated the association between adherence to the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) cancer prevention recommendations and HRQL both, at BC diagnosis and the change 7-12 years later.

DESIGN

Prospective cohort study.

SETTINGS AND PARTICIPANTS

A total of 406 breast cancer survivors, from the EpiGEICAM study, were recruited in 16 Spanish hospitals.

MEASUREMENTS

Epidemiological, clinical, dietary, physical activity and HRQL information was collected both at recruitment and 7-12 years later. A 7-item score to measure compliance with recommendations was assessed according to the 2018 WCRF/AICR scoring criteria. HRQL was evaluated using SF-36 questionnaire. Linear mixed models for longitudinal data were used to assess the cross-sectional and longitudinal association between adherence score and the physical and mental component summary scores.

RESULTS

At diagnosis, for each unit increase in WCRF/AICR score adherence, the HRQL physical domain increased 0.78 points (95%CI: -0.04 to 1.60; P trend:0.06). The mean change in physical HRQL from diagnosis to follow-up per unit increase in within-subject adherence score was 0.73 points (95%CI: -0.18 to 1.65; P trend: 0.12). For the mental domain, no association was observed with compliance with the recommendations at diagnosis, nor with changes in adherence over time.

CONCLUSIONS

Our results suggest that Increased adherence to WCRF/AICR cancer prevention recommendations over time could contribute to slightly improved long-term physical HRQoL in BC survivors.

Psychological distress and health behaviours in people living with and beyond cancer: a cross-sectional study

This study aimed to examine whether psychological distress was cross-sectionally associated with meeting World Cancer Research Fund (WCRF) recommendations in people living with and beyond cancer. Participants were adults living with and beyond breast, prostate and colorectal cancer, participating in the baseline wave of the Advancing Survivorship after Cancer Outcomes Trial (ASCOT). Anxiety/depression was assessed using the EQ-5D-5L and dichotomised into any/no problems. WCRF recommendations were assessed via pedometers, 24-h dietary recalls, self-reported alcohol intake (AUDIT-C), and self-reported smoking status. Participants were categorised as meeting WCRF recommendations using the following cut-offs: average daily steps (≥ 10,000/day), average weekly aerobic steps (≥ 15,000/day), fruit and vegetables (≥ 400 g/day), fibre (≥ 30 g/day), red meat (< 500 g/week), processed meat (0 g/day), high calorie food (fat ≤ 33% of total daily energy intake and free sugar ≤ 5% of total daily energy intake), alcohol (≤ 14 units/week) and smoking (non-smoking). A composite health behaviour risk index (CHBRI) was calculated by summing the number of WCRF recommendations met (range: 0-9). Among 1348 participants (mean age = 64 years (SD = 11.4)), 41.5% reported anxiety/depression problems. The mean CHBRI score was 4.4 (SD = 1.4). Anxiety/depression problems were associated with lower odds of meeting WCRF recommendations for average daily steps (odds ratio (OR) = 0.73; 95% CI 0.55, 0.97), but not for any other health behaviour. Psychological distress is associated with lower adherence to WCRF recommendations for physical activity in people living with and beyond cancer. Physical activity may be a mechanism linking psychological distress and poorer outcomes among people living with and beyond cancer, and this should be explored in longitudinal studies.

Depressive Symptoms, Socioeconomic Position, and Mortality in Older People Living With and Beyond Cancer

OBJECTIVE

Evidence shows that higher depressive symptoms are associated with mortality among people living with and beyond cancer (LWBC). However, prior studies have not accounted for a wider range of potential confounders, and no study has explored whether socioeconomic position (SEP) moderates the association. This study aimed to examine the association between depressive symptoms and mortality among people LWBC, and moderation by SEP.

METHODS

Participants from the English Longitudinal Study of Aging, diagnosed with cancer and with a measure of depressive symptoms within 4 years after their diagnosis, were included. Elevated depressive symptoms were indicated by a score of ≥3 on the eight-item Center for Epidemiologic Studies Depression Scale. Cox regression models examined associations with all-cause mortality. Competing risk regression examined associations with cancer mortality.

RESULTS

In 1352 people LWBC (mean age = 69.6 years), elevated depressive symptoms were associated with a 93% increased risk of all-cause mortality (95% confidence interval = 1.52-2.45) within the first 4 years of follow-up and a 48% increased risk within a 4- to 8-year follow-up (95% confidence interval = 1.02-2.13) after multivariable adjustment. Elevated depressive symptoms were associated with a 38% increased risk of cancer mortality, but not after excluding people who died within 1 year after baseline assessments. There were no interactions between depressive symptoms and SEP.

CONCLUSIONS

Elevated depressive symptoms are associated with a greater risk of all-cause mortality among people LWBC within an 8-year follow-up period. Associations between depressive symptoms and cancer mortality might be due to reverse causality.

Lifestyle Behaviors and Health-Related Quality of Life in Cancer Survivors: A Latent Class Analysis

Healthy lifestyle behaviors can improve health-related quality of life (HRQOL) in cancer survivors; but the combination of behaviors most important for HRQOL is not known. This study investigated the patterns of lifestyle behaviors among cancer survivors and differences in HRQOL between behavioral classes. Cancer survivors (n = 2,463) were invited to participate in a cross-sectional survey. Participants (N = 591) were predominately female (63%) and non-Hispanic White (90%). Survey items included self-reported physical activity, diet, smoking, sleep, HRQOL, and demographics. Behavioral classes were estimated by latent class analysis. Differences between classes were assessed by latent class regression. Compared with the "healthy lifestyles" class (higher probabilities of meeting aerobic/strength-based activity guidelines, high fruit/vegetable intake, and no sleep problems; 11% of sample), the "sleep and diet problems with inconsistent physical activity" class (higher probabilities of not meeting strength-based guidelines, low fruit/vegetable intake, some sleep problems; marginally higher probability of meeting aerobic guidelines; 41%) had poorer general and physical HRQOL. The "poor physical activity and diet" class (higher probabilities of not meeting aerobic/strength-based guidelines, low fruit/vegetable intake, and some sleep problems; 48%) had poorer general, physical, and mental HRQOL. Few participants exhibited healthy lifestyle patterns associated with HRQOL. The findings provide opportunities to develop differentiated multiple behavior-change interventions, targeted to two common patterns of behavior. A large subgroup of cancer survivors was susceptible to suboptimal physical activity and diet, warranting interventions exclusively targeting these behaviors. Another subgroup was susceptible to suboptimal physical activity, diet, and sleep, indicating interventions for this group should include strategies targeting these three behaviors.

Prevalence of health behaviors among cancer survivors in the United States

PURPOSE

We determined the proportion of cancer survivors who met each of five health behavior guidelines recommended by the American Cancer Society (ACS), including consuming fruits and vegetables at least five times/day, maintaining a body mass index (BMI) < 30 kg/m2, engaging in 150 min or more of physical activity weekly, not currently smoking, and not excessively drinking alcohol.

METHODS

Using data from the 2019 Behavioral Risk Factor Surveillance System (BRFSS), 42,727 survey respondents who reported a previous diagnosis of cancer (excluding skin cancer) were included. Weighted percentages with 95% confidence intervals (95% CI) were estimated for the five health behaviors accounting for BRFSS' complex survey design.

RESULTS

The weighted percentage of cancer survivors who met ACS guidelines was 15.1% (95%CI: 14.3%, 15.9%) for fruit and vegetable intake; 66.8% (95%CI: 65.9%, 67.7%) for BMI < 30 kg/m2; 51.1% (95%CI: 50.1%, 52.1%) for physical activity; 84.9% (95%CI: 84.1%, 85.7%) for not currently smoking; and 89.5% (95%CI: 88.8%, 90.3%) for not drinking excessive alcohol. Adherence to ACS guidelines among cancer survivors generally increased with increasing age, income, and education.

CONCLUSIONS

While the majority of cancer survivors met the guidelines for not smoking and limiting alcohol drinking, one-third had elevated BMI, almost half did not meet recommended physical activity levels, and the majority had inadequate fruit and vegetable intake.

IMPLICATIONS FOR CANCER SURVIVORS

Adherence to guidelines was lowest among younger cancer survivors and those with lower income and education, suggesting these may be populations where resources could be targeted to have the greatest impact.

A latent class analysis of health behavior changes after cancer diagnosis among Hispanic/Latino cancer survivors

PURPOSE

We aimed to identify subgroups of Hispanic/Latino (H/L) cancer survivors with distinct health behavior patterns and their associated sociodemographic, medical, and psychosocial characteristics.

METHODS

Baseline data were used from a randomized clinical trial evaluating the efficacy of an enhanced patient navigation intervention in H/L cancer survivors. Participants (n = 278) completed the Lifestyle Behavior Scale and validated questionnaires on health-related quality of life (HRQOL), supportive care needs, distress, and satisfaction with cancer care. Latent class analysis was used to determine the latent classes and associated characteristics.

RESULTS

Three latent classes emerged: class 1 (survivors who increased health behaviors [e.g., exercising and eating healthy] since diagnosis); class 2 (no changes in health behaviors since diagnosis); and class 3 (a "mixed class," with a higher or lower engagement across various health behaviors since diagnosis). Participants in class 1 were significantly more educated and less likely to be foreign born. Participants in class 2 were significantly older and more likely to have prostate cancer. H/L cancer survivors in class 3 had a significantly lower income, were less educated, and reported greater unmet supportive care needs, more distress, and poorer HRQOL.

CONCLUSIONS

Survivors who report engaging in health behaviors less frequently since diagnosis may be experiencing psychosocial challenges and health disparities.

IMPLICATIONS FOR CANCER SURVIVORS

Hispanic/Latino cancer survivors may benefit from screening for social determinants of health and mental health needs, prompt referral to supportive care services, community resources, and public services, and participating in culturally informed psychosocial interventions to address their unique needs.

Pilot Randomized Controlled Trial of Lymfit: A Theory-Guided Exercise Intervention for Young Adults with Lymphoma

Despite the rapidly emerging evidence on the contributions of physical activity to improving cancer-related health outcomes, adherence to physical activity among young adults with lymphoma remains suboptimal. Guided by self-determination theory (SDT), the Lymfit intervention (a 12-week individualized exercise program with bi-weekly kinesiologist support and an activity tracker) aimed to foster autonomous motivation toward physical activity. This pilot randomized controlled trial aimed to evaluate the feasibility, acceptability, and preliminary effects of Lymfit. Young adults (N = 26; mean age of 32.1 years) with lymphoma who were newly diagnosed and those up to six months after completing treatment were recruited and randomly assigned one-to-one to either the intervention group (n = 13) or a wait-list control group (n = 13). All a priori feasibility benchmarks were met, confirming the feasibility of the study in terms of recruitment uptake, retention, questionnaire completion, intervention fidelity, missing data, Fitbit wear adherence, and control group design. The intervention acceptability assessment showed high ratings, with eight out of ten items receiving >80% high ratings. At post-intervention, an analysis of covariance models showed a clinically significant increase in self-reported physical activity levels, psychological need satisfaction, and exercise motivation in the intervention group compared to controls. Lymfit also led to meaningful changes in six quality-of-life domains in the intervention group, including anxiety, depression, fatigue, sleep disturbance, social roles and activities, and pain interference. The findings support Lymfit as a promising means to meet psychological needs and increase the autonomous motivation for physical activity in this group. A fully powered efficacy trial is warranted to assess the validity of these findings.

Co-designing Healthy Living after Cancer Online: an online nutrition, physical activity, and psychosocial intervention for post-treatment cancer survivors

PURPOSE

The aim of the present study was to co-design Healthy Living after Cancer Online (HLaC Online), an online intervention supporting cancer survivors to set and meet their healthy living goals.

METHODS

Adapted from an initial telephone-delivered Healthy Living after Cancer program, wireframes (PDF black and white mock-ups) of the proposed online program were presented in a series of focus groups and interviews to our stakeholder group, which consisted of cancer survivors, oncology healthcare professionals, and representatives from cancer support organisations. Stakeholders were prompted for feedback on the wireframe and given end-user scenarios to encourage deeper engagement with the co-design process. Transcriptions underwent thematic analysis to determine which features of the program needed change or expansion.

RESULTS

27 participants took part in one of 8 focus groups or 10 interviews. Five themes were identified relating to (a) website design elements, (b) promoting and maintaining long-term engagement, (c) relatability and relevance, (d) navigating professional support, and (e) family and peer support. Recommended changes, such as simple activities and guidance videos, were integrated into the HLaC Online prototype.

CONCLUSIONS

Involving end-users in the co-design process ensured the intervention's relevance and specificity to the needs of cancer survivors. Next steps include feasibility testing the prototype, prior to commencing a national randomised control trial of HLaC Online.

IMPLICATIONS FOR CANCER SURVIVORS

HLaC Online aims to support cancer survivors to improve their quality of life by making healthy lifestyle changes in their physical activity, healthy eating, weight management, mental health, and fatigue management.

Motivation for Health Promotion in Cancer Survivors: An Evolutionary Concept Analysis

Motivation for health promotion is an essential concept in health care research, as it pertains to an individual's ability to adapt to the adversity of chronic illnesses, including cancer. Adopting Rodgers' evolutionary method of concept analysis, the objective of this article is to clarify the concept based on its existing operationalization noted in cancer survivorship literature. Through a close examination of the construction of the concept, this article facilitates the understanding of concept as it relates to the field of cancer survivorship care, which in turn helps provide guidance for developing health promotion intervention targeted at cancer survivors.

Factors Influencing Health Promotion Lifestyle in Female Breast Cancer Survivors: The Role of Health Behavior Self-Efficacy and Associated Factors

OBJECTIVES

To examine the factors influencing health-promoting lifestyles and the changes in health behavior self-efficacy and health-promoting lifestyles among female breast cancer survivors over a 6-month period.

METHODS

A longitudinal design with purposive sampling was deployed. Data collection occurred at the baseline (T1), 3 months (T2), and 6 months (T3). In total, 53 breast cancer survivors agreed to participate. All participants completed the first two rounds of data collection, 49 participants completed data collection at the 6-month mark (T3). The Chinese versions of the Self-Rated Abilities for Health Practices Scale (SRAHP) and the Health-Promoting Lifestyle Profile (HPLP) were used.

RESULTS

Health behavior self-efficacy and health-promoting lifestyle scores increased over time. Age, impaired cardiac function, those taking a career break, psychological well-being, and responsible health practice in self-efficacy for health behaviors were significant predictors of health-promoting lifestyle.

CONCLUSIONS

Younger breast cancer survivors, those taking a career break, and those with poor health behavior self-efficacy were less likely to engage in a health-promoting lifestyle and may require guidance in improving overall health behaviors.

IMPLICATIONS FOR NURSING PRACTICE

Healthcare providers should not only be aware of the suboptimal health promotion lifestyle in breast cancer survivors but also focus on enhancing health behavior self-efficacy. This is particularly crucial for younger breast cancer survivors or those currently unemployed.

Adherence to the World Cancer Research Fund/American Institute for Cancer Research recommendations for cancer prevention in adolescent and young adult (AYA) cancer survivors: results from the SURVAYA study

PURPOSE

For adolescent and young adult (AYA) cancer survivors with a good prognosis, having a healthy lifestyle prevents morbidity and mortality after treatment. The aim of this study was to investigate the prevalence of (un)healthy lifestyle behaviors and related determinants in AYA cancer survivors.

METHODS

A population-based, cross-sectional study was performed among long-term (5-20 years) AYA cancer survivors (18-39 years old at diagnosis) registered within the Netherlands Cancer Registry. Self-reported questionnaires data about health behaviors were used to calculate the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) adherence score. Associations between the score and clinical/sociodemographic determinants of (un)healthy behaviors were investigated using logistic regression models.

RESULTS

The mean WCRF/AICR score was low to moderate, 3.8 ± 1.2 (0.5-7.0) (n = 3668). Sixty-one percent adhered to "limit the consumption of sugar sweetened drinks," 28% to "be a healthy weight," 25% to "fruit and vegetable consumption," and 31% to "limit alcohol consumption." Moderate and high adherence were associated with being a woman (ORmoderate = 1.46, 95% CI = 1.14-1.85, and ORhigh = 1.87, 95% CI = 1.46-2.4) and highly educated (ORmoderate = 1.54, 95% CI = 1.30-1.83, and ORhigh = 1.87, 95% CI = 1.46-2.4). Low adherence was associated with smoking (ORmoderate = 0.68, 95% CI = 0.50-0.92, and ORhigh = 0.30, 95% CI = 0.21-0.44) and diagnosis of germ cell tumor (ORmoderate = 0.58, 95% CI = 0.39-0.86, and ORhigh = 0.45, 95% CI = 0.30-0.69).

CONCLUSIONS

Adherence to the 2018 WCRF/AICR lifestyle recommendations was low to moderate, especially regarding body weight, fruit, vegetables, and alcohol consumption. Men, current smokers, lower-educated participants, and/or those diagnosed with germ cell tumors were less likely to have a healthy lifestyle.

IMPLICATIONS FOR CANCER SURVIVORS

Health-promotion programs (e.g., age-specific tools) are needed, focusing on high-risk groups.

Designing viable, durable physical activity programs for cancer survivors: reflections from program participants and organizational leaders

PURPOSE

Despite recommendations for cancer survivors to participate in routine physical activity (PA), offering programs that fit both survivors' needs and sponsoring organizations' resources remains a challenge. The purpose of this study is to explore the perspectives of cancer survivors and organizational stakeholders with the intent of developing PA peer-led programs that organizations can implement into their programming.

METHODS

This study explored cancer survivors' (n = 11) and cancer care organizational stakeholders' (n = 27) perspectives on the design and feasibility of PA programs targeted for cancer survivors. Semi-structured interview guides were developed for survivors and stakeholders; interviews lasted approximately 30 min. Two analysts used a thematic analysis approach and independently conducted a line-by-line coding of each transcript. With guidance from a senior analyst, the codes were collapsed into themes and subthemes.

RESULTS

The qualitative analysis of the interview data resulted in seven major themes relating to PA program development and success. Survivor-related themes included the following: (1) developing PA programs based on cancer survivors' characteristics and experiences; (2) perceived value and importance of accessible, face-to-face instruction; (3) ensuring success based on physical abilities and limitations of the survivor; and (4) the value of physician recommendation for PA participation. Organization-related themes included the following: (1) incorporating participant and community input into program offerings; (2) program feasibility and sustainability; (3) incorporating organizational experience when adopting new program initiatives.

CONCLUSION

These findings highlight the challenges of developing viable PA programs for cancer survivors and may guide organizations in future program development and implementation.

Phytonutrients and outcomes following breast cancer: a systematic review and meta-analysis of observational studies

BACKGROUND

Phytonutrient intakes may improve outcomes following breast cancer, but the impact of postdiagnosis introduction vs established prediagnostic exposure as well as optimum doses has not been established. Evidence from observational studies for key exposures was evaluated, including dosage and intake time frames.

METHODS

MEDLINE, EMBASE, CINAHL, Cochrane Library, ClinicalTrials.gov, and the ISRCTN registry were searched for prospective and retrospective observational studies investigating the impact of soybean, lignans, cruciferous (cabbage-family) vegetables, green tea, or their phytonutrients on breast cancer survival outcomes. A random-effects model was used to calculate summary hazard ratios (HRs) and 95% confidence intervals (CIs). Nonlinear dose-response analyses were conducted using restricted cubic splines.

RESULTS

Thirty-two articles were included. Soy isoflavones were associated with a 26% reduced risk of recurrence (HR = 0.74, 95% CI = 0.60 to 0.92), particularly among postmenopausal (HR = 0.72, 95% CI = 0.55 to 0.94) and estrogen receptor-positive survivors (HR = 0.82, 95% CI = 0.70 to 0.97), with the greatest risk reduction at 60 mg/day. In mortality outcomes, the reduction was mostly at 20 to 40 mg/day. Soy protein and products were inversely associated with cancer-specific mortality for estrogen receptor-positive disease (HR = 0.75, 95% CI = 0.60 to 0.92). An inverse association was observed for serum or plasma enterolactone, measured prediagnosis and early postdiagnosis, with cancer-specific mortality (HR = 0.72, 95% CI = 0.58 to 0.90) and all-cause mortality (HR = 0.69, 95% CI = 0.57 to 0.83). No effects were observed for cruciferous vegetables. There was a 44% reduced risk of recurrence with prediagnostic green tea for stage I and II breast cancer (HR = 0.56, 95% CI = 0.38 to 0.83).

CONCLUSIONS

Soy, enterolactone, and green tea demonstrated significant risk reductions in outcomes following breast cancer. Evidence is needed regarding the impact of postdiagnostic introduction or substantial increase of these exposures.

A Systematic Review of Dietary Interventions for Cancer Survivors and Their Families or Caregivers

Family or caregiver engagement has the potential to support healthy dietary changes among cancer survivors. However, little is known about these family- or caregiver-involved dietary interventions and their effects. This systematic review aimed to identify the behavior change techniques (BCTs) used in dietary interventions for cancer survivors and their families or caregivers and to synthesize intervention effects on dietary and health outcomes. Following the PRISMA guidelines, we conducted systematic searches in three databases and identified 12 trials (16 peer-reviewed manuscripts) for inclusion in this review. Data were extracted from these manuscripts and the BCT taxonomy was used to identify the BCTs. A total of 38 BCTs were identified from 12 trials, 13 of which were used in at least half of the 12 trials. Ten studies reported significant intervention effects on health outcomes (e.g., adiposity) and six suggested significant improvements in dietary behaviors (e.g., fruit and vegetable intake). Overall, this review found that family- or caregiver-involved interventions for cancer survivors significantly improved dietary and health outcomes. Future research should identify BCTs particularly for dietary changes and develop effective dyadic strategies to facilitate diet-related interactions between survivors and their families or caregivers to enhance their engagement in healthy diets.

Associations between modifiable lifestyle factors and health-related quality of life among endometrial carcinoma survivors - A cross-sectional study

OBJECTIVE

To explore possible associations between modifiable lifestyle factors and health-related quality of life (HRQoL) in endometrial carcinoma survivors by assessing differences in HRQoL between survivors meeting and not meeting the World Health Organization's (WHO) recommendations regarding physical activity, BMI, and smoking.

METHODS

This was a cross-sectional population-based study in women having undergone surgery for assumed early-stage endometrial carcinoma. Thresholds for clinical importance based on the EORTC QoL working group were used to interpret scores. Effect size (ES) was interpreted as small (d = 0.2-0.49), medium (d = 0.5-0.8), and large (d > 0.8).

RESULTS

In total, 1200 evaluable women were included. Meeting physical activity recommendations and BMI <25 kg/m2 was associated with significantly better global health status, (ES) = 0.18 and ES = -0.11, respectively. On multivariate analysis, women meeting physical activity recommendations had significantly higher scores on physical- (ES = 0.31), role- (ES = 0.15), and social functioning (ES = 0.15), and lower levels of fatigue (ES = -0.16), pain (ES = -0.10), and appetite loss (ES = -0.15) (all p < 0.05) compared to non-meeting survivors. Participants with BMI ≥25 kg/m2 had lower scores for social functioning (ES = -0.10), and higher levels of pain (ES = 0.13) and dyspnea (ES = 0.12) (all p < 0.05) compared to those with BMI <25 kg/m2. Smokers had lower scores for emotional functioning (ES = -0.09) and higher levels of diarrhea (ES = 0.10) (all p < 0.05) compared to non-smokers.

CONCLUSION

Meeting WHO recommendations for modifiable life-style factors is associated with better HRQoL among endometrial carcinoma survivors: Being sufficiently physical active and having a BMI <25 kg/m2 are significantly associated with better self-reported global health status. All modifiable factors are associated with better functioning, and reduced symptom-burden.

Dietary Barriers Appear to Influence the Effects of a Dyadic Web-Based Lifestyle Intervention on Caloric Intake and Adiposity: A Mediation Analysis of the DUET Trial

Mechanisms that explain behavior change within web-based lifestyle interventions are not well-studied. This secondary analysis explores whether the effects of the DUET web-based lifestyle intervention on diet, physical activity, and/or adiposity are mediated through changes in self-efficacy, social support, and perceived barriers (key constructs of social cognitive theory). Data on mediators, diet quality, caloric intake, moderate-to-vigorous physical activity (MVPA), weight, and waist circumference (WC) were analyzed from 112 cancer survivors and their partners enrolled in the DUET intervention. Mediation analyses were performed using Mplus to execute regression analyses and determine associations. Mediation analyses supported an effect of the intervention on caloric intake (-3.52, 95% CI [-8.08 to -0.84]), weight (-1.60, CI [-3.84 to -0.47]), and WC (-0.83, CI [-1.77 to -0.18]), interpreting these negative associations as intervention induced reductions in dietary barriers. Higher social support was significantly and positively associated with, but not a mediator for, improvements in self-reported and accelerometry-measured MVPA (b = 0.69, CI [0.19, 1.24]) and (b = 0.55, CI [0.15, 1.00]), respectively. Self-efficacy did not appear to mediate the intervention's effects. Findings suggest that the effects of the DUET intervention on diet and adiposity stem from reducing perceived barriers to a healthful, low-calorie diet.

Development and psychometric properties of Health-Promoting Lifestyle Scale in Colorectal Cancer Survivors (HPLS-CRCS): a mixed-method study

BACKGROUND

Detecting a health-promoting lifestyle in colorectal cancer (CRC) survivors is of paramount importance to manage disease complications, prevent their recurrence, and enhance survival; however, no specialized tool has yet been provided to measure the lifestyle of these patients. Accordingly, this study aimed to develop and determine the psychometric properties of the Health-Promoting Lifestyle Scale in CRC Survivors (HPLS-CRCS).

METHODS

This study was a mixed study with an exploratory sequential design in two phases. Concept analysis was performed in the first phase according to Schwartz-Barcott and Kim's (2000) hybrid model to explain the concept, identify dimensions, and generate items. In the second phase, psychometrics including validity (face, content, and construct) and reliability (internal consistency and stability) were determined. Responsiveness, interpretability, ease of use, item weighting, and scale scoring were also determined.

RESULTS

After explaining the concept, an initial scale encompassing 211 items was developed, content and item analyses were conducted, and the items decreased to 89 items after the face validity assessment. For construct validity, confirmatory factor analysis (CFA) was conducted with a sample size of 500 survivors, and convergent validity was performed for the Persian version of the Health-Promoting Lifestyle Profile II (HPLP-II). Accordingly, 80 items were classified into six factors: activity and rest, spiritual growth, health responsibility, nutrition, interpersonal relationships, and psychological management, with RMSEA = 0.055, χ2/df = 2.484, and χ2 = 6816.516. The reliability of the scale was confirmed, Cronbach's alpha was between 0.865 and 0.928, and the intraclass correlation coefficient (ICC), the standard error of measurement (SEM), the minimal important change (MIC), and the smallest detectable change (SDC) were 0.896, 3.36, 13.86, and 19.87, respectively.

CONCLUSION

The HPLS-CRCS consists of 80 items in six dimensions and is a valid and reliable scale for evaluating the health-promoting lifestyle in CRC survivors. Using this scale to evaluate the healthy lifestyle in these survivors can lead healthcare providers to detect deficiencies and plan the lifestyle of CRC survivors during the post-treatment period.

The impact of the COVID-19 pandemic on the health behaviours of people living with and beyond breast, prostate, and colorectal cancer-a qualitative study

PURPOSE

Positive health behaviours (sufficient exercise, healthy diet, limiting alcohol, and not smoking) can improve multiple outcomes after a cancer diagnosis. Observational studies suggest that health behaviours were negatively impacted for some but not all individuals living with and beyond cancer. The aim of this study was to qualitatively explore the impact of the pandemic on health behaviours of people in this population.

METHODS

Thirty participants were purposively sampled for characteristics including diagnostic group (breast, prostate, and colorectal cancers), gender, time since diagnosis, and age. Semi-structured interviews were conducted to discuss the impact of the pandemic on health behaviours. Thematic analysis and a secondary Ideal Types analysis were conducted.

RESULTS

Five themes covered changes in food, weight management, relationship to alcohol, and exercise. Five "types" were identified, representing orientations to health behaviours. The "gift of time" provided by the pandemic had an impact on health behaviours, with trends towards increases in drinking, eating unhealthy food, and exercising less.

CONCLUSIONS

The COVID-19 pandemic impacted engagement in positive health behaviours among participants in this study. Strict restrictions and changes in routines resulted in individuals adjusting how they managed their diet, alcohol intake, and exercise behaviours. The typology identified within this study helps to define how different orientation to health behaviours could underpin the responses of individual people LWBC.

IMPLICATIONS FOR CANCER SURVIVORS

Alongside providing an understanding of the experiences of people LWBC during the COVID-19 pandemic, the proposed typology suggests how, with further development, future health behaviour interventions in this group could be targeted based on individual orientations to health, rather than demographic or clinical variables.

Health information avoidance and health promotion behavior in patients with enterostomy

BACKGROUND

Enterostomy is currently the main treatment method for colorectal cancer. Health promotion behavior can improve the quality of life of patients undergoing enterostomy and is of great significance in maintaining their health status. However, health information avoidance can drive patients to avoid health risk information, which is not conducive to their own health. This study hypothesized that health information avoidance in patients undergoing colostomy is the main factor influencing health promotion behavior.

AIM

To investigate the status of health information avoidance and health promoting behavior among enterostomy patients and discuss their relationship, in order to provide reference for improving the prognosis and quality of life of patients with enterostomy.

METHODS

By using the convenient sampling method, 205 enterostomy patients were selected from a hospital in Qingdao. General information questionnaire, Health Information Avoidance Scale, and Health Promoting Lifestyle Profile-Ⅱ were used to conduct the investigation.

RESULTS

The health information avoidance score of patients with enterostomy was (25.99 ± 8.81), and 105 patients (56.10%) had varying degrees of health information avoidance behavior, of whom 64 (31.20%) had mild avoidance and 41 (24.90%) had severe avoidance. The Health Promoting Lifestyle Profile-Ⅱ score was (126.19 ± 15.32), which was overall in the middle level. Health information avoidance was negatively correlated with health promotion behavior. Multiple linear regression analysis showed that health information avoidance behavior was a significant influencing factor of health promotion behavior.

CONCLUSION

The health information avoidance behavior and health promotion behavior of patients with enterostomy need to be improved. The medical staff should understand the obstacles of patients in the process of receiving health information, in order to help them effectively cope with the avoidance of health information and improve their health behavior and quality of life.

Lifestyle, clinical and histological indices-based prediction models for survival in cancer patients: a city-wide prospective cohort study in China

PURPOSE

We developed a nomogram to predict 3-year, 5-year and 7-year cancer survival rates of cancer patients.

METHODS

This prospective cohort study included 20,491 surviving patients first diagnosed with cancer in Guangzhou from 2010 to 2019. They were divided into a training and a validation group. Lifestyle, clinical and histological parameters (LCH) were included in multivariable Cox regression. Akaike information criterion was used to select prediction factors for the nomogram. The discrimination and calibration of models were assessed by concordance index (C-index), area under time-dependent receiver operating characteristic curve (time-dependent AUC), and calibration plots. We used net reclassification index (NRI) and integrated discrimination improvement (IDI) to compare the clinical utility of LCH prediction model with the prediction model based on lifestyle factors (LF).

RESULTS

13 prediction factors including age, sex, BMI, smoking status, physical activity, sleep duration, regular diet, tumor grading, TNM stage, multiple primary cancer and anatomical site were included in the LCH model. The LCH model showed satisfactory discrimination and calibration (C-index = 0.81 (95% CI 0.80-0.82) for training group and 0.80 (0.79-0.81) for validation group, both time-dependent AUC > 0.70). The LF model including smoking status, physical activity, sleep duration, regular diet, and BMI showed less satisfactory discrimination (C-index = 0.60 (95% CI 0.59-0.61) for training and 0.60 (0.58-0.62) for validation group). The LCH model had better accuracy and discriminative ability than the LF model, as indicated by positive NRI and IDI values.

CONCLUSIONS

The LCH model shows good accuracy, clinical utility and precise prognosis prediction, and may serve as a tool to predict cancer survival of cancer patients.

Adherence to lifestyle recommendations among Norwegian cancer survivors and the impact of traditional and complementary medicine use: the Tromsø Study 2015-2016

INTRODUCTION

Adherence to healthy lifestyle recommendations has positive effects on cancer outcomes yet adherence is low among cancer survivors. Differences in adherence between women and men, phase of survivorship, and other factors that might increase adherence, like the use of traditional and complementary medicine (T&CM), need to be explored. We aimed to study the adherence to national recommendations for a healthy diet (daily intake of ≥ 5 portions of fruit/vegetables), physical activity (150 min of moderate-intensity or 75 min of high-intensity/week), normal body mass index (BMI) (18.5-24.9 kg/m2), non-smoking, and low-risk alcohol consumption (women ≤ 10 g/day, men ≤ 20 g/day) among Norwegian cancer survivors and their associations with sex, the use of T&CM, and survivorship phase.

METHODS

We used logistic regression, independent sample t-test, and chi-square test to study self-reported (diet, physical activity, smoking, alcohol consumption) and measured (BMI) adherence in 1530 cancer survivors (40 years and above, participating in the population-based Tromsø Study conducted in 2015-2016 (65% attendance). We dichotomized all assessed lifestyle recommendations (adherence = 1 point, non-adherence = 0 points), and created a score for every recommendation (0-5 points). Adherence to individual lifestyle recommendations and the use of T&CM as well as the phase of survivorship was adjusted for sex, age, income, and living with a partner.

RESULTS

Adherence to recommendations was 7.5% for diet, 85.3% for physical activity, 30.5% for BMI, 89.3% for non-smoking, and 87.6% for alcohol consumption. In total 2.3% adhered to all five recommendations concurrently (mean score 2.96 [SD = 0.86]). Women adhered to more recommendations concurrently compared to men (3.03 [SD = 0.90] vs. 2.89 [SD = 0.80] points respectively, [p = .012]). In total, 31% reported the use of T&CM and there were no differences in adherence to individual lifestyle recommendations or concurrent adherence in overall T&CM use compared to non-use. Users of self-help techniques were more likely to adhere to the recommendations of diet (aOR 2.69, 95% CI 1.45-4.98) and physical activity (aOR 6.26, 95% CI 1.51-25.92). Users of traditional healers and users of more than one T&CM modality were less likely to adhere to the low-risk alcohol consumption recommendation, (aOR 0.32, 95% CI 0.13-0.77, and aOR 0.53, 95% CI 1.08-2.17, respectively) compared to T&CM non-users. Survivors with cancer previously (1162) had higher odds of adhering to the recommendation of diet (aOR 2.66, 95% CI 1.36-5.19) than survivors with cancer presently (n = 368), but not to other recommendations.

CONCLUSION

The health of cancer survivors can be improved through adherence to lifestyle recommendations, yet our study found partial adherence among survivors in Norway, in accordance with findings from other countries. Although overall T&CM use was not associated with higher adherence to lifestyle recommendations, differences in adherence were seen among individual modalities like the use of self-help techniques and traditional healers. Our results suggest the need for intensified follow-up of lifestyle with attention to male survivors and diet among all survivors throughout the cancer survivorship continuum.

Factors Associated with Dietary Habit Changes in Korean Stomach Cancer Survivors after Cancer Treatment

The current nutritional guidelines for stomach cancer survivors (SCSs) mainly focus on the influence of the surgical resection of the stomach, with limited guidance regarding a wider range of food options. We aimed to investigate the factors associated with healthier dietary changes in Korean adult SCSs. This cross-sectional study assessed dietary pattern changes after cancer treatment for 11 food categories, using a self-administered questionnaire. A 'healthier dietary change' was operationally defined as a reduced consumption of red and processed meat, grains, salt, and burnt food, and an increased consumption of poultry, fish, vegetables, fruits, legumes, and dairy products. Among a total of 624 SCSs, approximately 60% of participants reported dietary changes in a healthier direction in three or more food categories, while 9.1% reported no changes. There was no significant difference in dietary habit changes between surgery types. Multivariable adjusted analysis showed that elderly and long-term survivors were inversely associated with a healthier dietary change. SCSs with a higher level of educational achievement and income were more likely to make healthier changes in their intake of processed meat, vegetables, fruits, burnt food, or salt. SCSs with higher levels of fear of cancer recurrence, anxiety, or depression were more likely to follow healthier dietary changes regarding fish, meat, fruits, grains, or burnt food. Change in dietary pattern varied across different food items, and was associated with various characteristics of SCSs. It is crucial to repeatedly provide SCSs with information about healthier dietary patterns, considering their sociodemographic, clinical, and psychological characteristics.

Sociodemographic and Health Correlates of Multiple Health Behavior Adherence among Cancer Survivors: A Latent Class Analysis

The study aimed to (a) assess current levels of adherence to the National Comprehensive Cancer Network's multiple health behavior guidelines and (b) identify characteristics of cancer survivors associated with different adherence levels. Cancer survivors (N = 661) were identified through the state registry and completed questionnaires. Latent class analysis (LCA) was used to identify patterns of adherence. Associations between predictors with the latent classes were reported as risk ratios. LCA identified three classes: lower- (39.6%), moderate- (52.0%), and high-risk lifestyle (8.3%). Participants in the lower-risk lifestyle class had the highest probability of meeting most of the multiple health behavior guidelines compared to participants in the high-risk lifestyle class. Characteristics associated with membership in the moderate-risk lifestyle class included self-identifying as a race other than Asian/Asian American, being never married, having some college education, and having been diagnosed with later stage colorectal or lung cancer. Those in the high-risk lifestyle class were more likely to be male, never married, have a high school diploma or less, diagnosed with colorectal or lung cancer, and diagnosed with pulmonary comorbidities. Study findings can be used to inform development of future interventions to promote multiple health behavior adherence among higher risk cancer survivors.

Health behaviors, obesity, and marital status among cancer survivors: a MEPS study

PURPOSE

Promoting positive health behaviors helps improve cancer survivors' health outcomes during survivorship; however, little is known about whether health behaviors differ by marital status. The purpose is to examine whether health behaviors and obesity among cancer survivors vary by marital status and whether the type of cancer and sociodemographic factors influence the relationship.

METHODS

We examined smoking, physical activity, and body mass index (BMI) among 1880 individuals diagnosed with prostate, breast, or colon cancer who were identified from the 2011-2017 Medical Expenditure Panel Survey (MEPS). We used Rao-Scott design-adjusted chi-square tests and weighted multivariable logistic regressions to achieve the research aims.

RESULTS

Current smoking behavior and BMI were significantly related to marital status. Survivors who had never married were the most likely to be current smokers across all cancer types. Married survivors were the most likely to be overweight or obese, while widowed survivors were the most likely to have a normal weight. The relationship between BMI and marital status varied by cancer type. Widowed colon cancer survivors were least likely to be overweight or obese; divorced/separated colon cancer survivors were most likely to be obese or overweight. Health behavior disparities were found among cancer survivors of different age, sex, race, and levels of education and income.

CONCLUSIONS

There were relationships between marital status, health behaviors, and obesity among cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Our results suggested that relationship status and sociodemographic factors need to be considered in tailoring interventions to promote health behaviors among cancer survivors.

Lifestyle factors in Black female breast cancer survivors—Descriptive results from an online pilot study

Background

Breast cancer (BC) research examining disparities in cancer survivorship and modifiable risk behaviors has been mostly cancer-specific, leaving relevant gaps in disparities research relating to other cancer survivorship outcomes, including cardiovascular disease (CVD). Maintaining healthy lifestyle behaviors is a critical component of successful cancer survivorship, where unhealthy behaviors may increase the risk for recurrence, second primary cancers, and incidence of new comorbid conditions, including CVD. The current study describes BC survivorship factors among an online pilot study of Black BC survivors in Maryland, with a focus on the burden of obesity, comorbidity, and behavioral factors associated with CVD risk.

Methods

Utilizing social media recruitment strategies and survivor networks, we recruited 100 Black female BC survivors to complete an online survey. Descriptive characteristics (demographic, clinical, and lifestyle factors) were analyzed in terms of frequencies, means, standard deviations (SD) overall and by county.

Results

The average ages at time of survey and at primary BC diagnosis were 58.6 years (SD = 10.1) and 49.1 years (SD = 10.2), respectively. More than half of the survivors reported having hypertension (51%); and while only 7% reported being obese at the time of BC diagnosis, 54% reported being obese at the time of survey which was on average 9 years post BC diagnosis. Only 28% of the survivors reported meeting weekly exercise recommendations. While 70% were never smokers, most ever smokers resided in Baltimore City/Baltimore County (n = 18 ever smokers).

Conclusion

Our pilot study identified at-risk BC survivors in Maryland due to the high prevalence of CVD risk factors (hypertension, obesity, limited exercise). These pilot study methods will inform a future statewide multilevel prospective study to improve health behaviors among Black BC survivors.

Modality preferences for health behaviour interventions for post-treatment cancer survivors: a theoretical investigation

PURPOSES

User preferences for how programs are delivered are an important consideration when developing healthy living interventions. The aim of this study was to investigate (a) if cancer survivors prefer telephone or internet delivery for a healthy living intervention and (b) what factors were associated with delivery preference.

METHODS

Australian cancer survivors (18 + years) were invited to complete an online or hardcopy cross-sectional survey measuring social and clinical demographic factors and validated measures of self-efficacy, health literacy, and social support.

RESULTS

Of the 168 respondents, the majority were female (n = 147, 92%) and breast cancer survivors (n = 122, 80%) and preferred internet delivery (n = 109, 65%). Participants who preferred internet delivery had a longer time since diagnosis (M = 9.85 years, SD = 8.20) compared to those who preferred telephone (M = 6.80 years, SD = 5.54), p = .03. However, logistic regression analyses demonstrated that no other variables (age, gender, socio-economic status, BMI, education, self-efficacy, health literacy, nor social support) had a direct association on delivery preference.

CONCLUSIONS

Cancer survivors appear to prefer internet delivery to telephone, particularly for those further along the survivorship trajectory. Future intervention development should therefore consider the internet modality for delivering accessible health interventions and offer the program to long-term cancer survivors. Whether these findings are replicable in the current post-pandemic phase is an important avenue for future research.

Concepts from behavioral theories can guide clinicians in coaching for behavior change

OBJECTIVES

Many patients do not engage in health behaviors that can control common, chronic illnesses. Clinicians have opportunities to promote health behaviors yet may lack skills for coaching effectively about health behaviors. Our aims are to: present definitions of coaching, propose concepts for coaching about behavior change from two theories, share theory-guided research on behavior change relevant to ambulatory care settings, and delineate how concepts from these theories can guide coaching.

METHODS

In our discussion, we explain how two behavioral theories are complementary and applicable to coaching, present empirical support for these theories, and describe applications of these concepts for practice.

CONCLUSIONS AND PRACTICE IMPLICATIONS

Self-determination theory can guide clinicians in how to interact with patients to meet patients' psychological needs, to promote health behaviors, and subsequent health status. Self-regulation theory can guide coaches in what concepts to address for behavior change. These complementary theories have been supported in rigorous research with adult populations in ambulatory care settings.

Plant-Based Diets and Cancer Prognosis: a Review of Recent Research

PURPOSE OF REVIEW

Although plant-based diets are recommended for cancer prevention, their role in cancer survival is still uncertain. The purpose of this systematic review is to summarize the association between postdiagnosis plant-based diets and prognosis in cancer survivors.

RECENT FINDINGS

There is indication that higher intake of plant-based foods was associated with improved prognosis in cancer survivors. For colorectal cancer survival, a better prognosis was observed for a high intake of whole grains and fibre. For breast cancer survival, a higher intake of fruit, vegetable and fibre and a moderate intake of soy/isoflavone were associated with beneficial outcomes. A higher vegetable fat intake was related to improved prognosis in prostate cancer survivors. Emerging evidence suggests benefits of postdiagnosis plant-based diets on prognosis in cancer survivors. However, given the high heterogeneity between studies, further research in cancer survivors, considering clinical factors (e.g. treatment, stage) and methodological aspects (e.g. timing of dietary assessment), is needed.

Application of the Updated WCRF/AICR Cancer Prevention Score as an Outcome for Cancer Survivors Participating in a Tailored and Intensive Dietary and Physical Activity Intervention

The World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) has defined evidence-based guidelines for cancer prevention. These recommendations have been operationalized into a quantitative index for individual assessment. Survivors of cancer are increasingly desiring guidance for diet and lifestyle, and in the absence of research in survivors, are often instructed to follow cancer prevention and public health guidelines. In this study, we examine the utility of the quantitative updated WCRF/AICR scoring criteria to assess change among cancer survivors with overweight/obesity (OW/OB) following an intensive behavioral intervention. We applied the WCRF/AICR scoring criteria (range 0−7) to examine changes over the duration of the study by paired t-tests. Two cancer survivor cohorts with OW/OB (n = 91) completed a six-month phase II clinical trial designed to improve dietary and physical activity patterns. At enrollment and post-intervention, participants completed assessments including anthropometrics, food frequency questionnaires, and objective evaluation of physical activity. Participants improved adherence to all scored recommendations, with a significant increase in mean score from enrollment (3.22 ± 1.06) to post-intervention (4.28 ± 1.04) (p < 0.001). Mean BMI and waist circumference improved (both p < 0.001). The greatest improvements were noted for fruit and non-starchy vegetable intakes (+39%, p < 0.001); the greatest decreases were observed for processed meat consumption (−70%, p < 0.001). The updated WCRF/AICR Score can be applied to cancer survivor intervention studies and provides a tool to compare trials in regard to the baseline status of populations enrolled and the success of the intervention. Future interventions incorporating standardized assessments will help guide effective strategies to improve the health and quality of life for cancer survivors.

Change Toward Healthier Lifestyles Is Associated With Better Health-Related Quality of Life in Long-Term Colorectal Cancer Survivors

BACKGROUND

Little is known about how changes in a constellation of lifestyle factors affect health-related quality of life (HRQoL) in colorectal cancer (CRC) survivors. Our study aimed to investigate the association between changes in healthy lifestyle and HRQoL over time in survivors of stage I-IV CRC.

METHODS

We included 2,283 long-term (≥5 years postdiagnosis) survivors. A healthy lifestyle score (HLS) comprising smoking, alcohol consumption, diet, physical activity, and body fatness was derived at diagnosis and 5-year follow-up (5YFU) and categorized as low, moderate, or high. We assessed HRQoL with the EORTC Quality of Life Questionnaire-Core 30 at 5YFU and 10-year follow-up. We used multivariable linear regression and linear mixed models to explore associations between changes in HLS and HRQoL over follow-up.

RESULTS

A low baseline HLS was associated with poorer functioning and global health/QoL and a higher symptom burden at 5YFU compared with a high baseline HLS. An improved HLS from baseline to 5YFU was associated with better functioning, higher global health/QoL, and fewer symptoms at 5YFU than a maintained-high HLS. In longitudinal analyses, improved HLS was associated with better functioning at follow-up. Survivors with a maintained-high or an improved HLS reported generally less fatigue, pain, and dyspnea at follow-ups compared with survivors with a maintained-low or decreased HLS.

CONCLUSIONS

Change toward a healthier lifestyle since diagnosis was associated with better HRQoL in long-term CRC survivors. Our results support the importance of maintaining and/or promoting a healthier lifestyle among CRC survivors postdiagnosis.

Impact of Lifestyle Interventions on Gynecologic Cancers: Beyond Diet and Exercise

A Lifestyle Medicine approach to compliment cancer care is less commonly researched or implemented for women with gynecologic cancers as compared to better funded malignancies such as breast, prostate, and colorectal. Yet, several gynecologic malignancies are linked to obesity, estrogen/metabolic signaling pathways, and altered tumor microenvironment which could benefit greatly from a lifestyle medicine program. Lifestyle medicine, an evidenced-based branch of science, has expanded to the prevention and treatment of disorders caused by lifestyle factors (including cancer). Modifiable lifestyle factors such as obesity, lack of physical activity/nutrient density, microbial dysbiosis, sleep disturbance, and chronic stressors contribute greatly to cancer morbidity and mortality worldwide. This overarching area of research is evolving with some subtopics in their infancy requiring further investigation. Modern tools have allowed for better understanding of mechanisms by which adiposity and inactivity affect tumor promoting signaling pathways as well as the local tumor environment. Through the evolving use of these sophisticated techniques, novel prognostic biomarkers have emerged to explore efficacy of pharmacologic and lifestyle interventions in cancer. This state-of-the-art review article appraises recent evidence for a lifestyle medicine approach, beyond diet and exercise, to optimize survivorship and quality of life for patients with gynecologic cancers and introduces the 8-week web-based comprehensive HEAL-GYN program.

Evaluation of disparities in maintaining healthy lifestyle behaviors among female cancer survivors by race/ethnicity and US nativity

BACKGROUND

There are well-known racial/ethnic disparities in maintaining healthy lifestyle behaviors throughout cancer survivorship among US-born women. Less is known about these associations among women born outside the US, as these women may experience disparities in survivorship care due to the lack of access to culturally appropriate health services. We evaluated disparities in the associations between race/ethnicity and US nativity and the likelihood of meeting recommendations for maintaining a healthy lifestyle during cancer survivorship.

METHODS

2044 female cancer survivors contributed data from the National Health and Nutrition Examination Survey (NHANES) (1999-2018). Adjusted odds ratios (aORs) and 95 % confidence intervals (CIs) were calculated with multivariable logistic regression models to measure the association between independent variables (race/ethnicity, US nativity, length of time in the US) and outcomes (obesity, meeting weekly physical activity (PA) recommendations, smoking history, alcoholic drinks/day) overall and by comorbidity.

RESULTS

Most survivors were breast cancer survivors (27.6 %), non-Hispanic white (64.2 %), and US native (84.5 %). Compared to US native survivors, foreign-born survivors were less likely (aOR, 0.30, 95 % CI, 0.10-0.87) to not meet PA recommendations, while foreign-born survivors living in the US ≥ 15 years were 2.30 times more likely (95 % CI, 1.12-4.73) to not meet PA recommendations. Having at least one comorbidity modified (p-interaction< 0.05) the relationships between US nativity and length of time in the US.

CONCLUSION

Our findings provide new evidence for disparities in maintaining healthy lifestyle behaviors among female cancer survivors and can help inform lifestyle interventions for female cancer survivors from different racial/ethnic backgrounds.

Supervised Exercise Interventions in Childhood Cancer Survivors: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background: Childhood cancer survivors (CCSs) may suffer from a multitude of health impairments, resulting in a compromised quality of life (QoL). This review’s objective was to examine CCSs’ adherence to supervised exercise training interventions and the impact of these interventions on health outcomes. Methods: The following databases were searched in May 2022: PubMed, Embase, Cochrane Library, and Web of Science. The included studies were limited to randomized controlled trials (RCTs), published in English involving CCSs aged 18 years and below. Results: Nine RCTs (n = 642 participants) were included in the systematic review, and seven of them (n = 551 participants) were included in the meta-analysis. Both the mean retention rate and adherence to the supervised exercise interventions were 87%. Supervised exercise interventions significantly improved muscle strength (standardized mean difference (SMD) = 1.42, p = 0.03), level of daily physical activity (SMD = 1.05, p < 0.001), body mass index (BMI) (mean difference (MD) = 1.06, p = 0.03), and fatigue (SMD = −0.44, p < 0.001), while there was no statistical significance in the quality of life (QoL) (SMD = 0.21, p = 0.20). Conclusions: The adherence of CCSs to supervised exercise interventions is high, and supervised exercise interventions are safe and effective.

American Cancer Society nutrition and physical activity guideline for cancer survivors

The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.

A systematic scoping review of post-treatment lifestyle interventions for adult cancer survivors and family members

PURPOSE

Supporting the health of cancer survivors and their families from diagnosis through survivorship is a recognized priority. However, the extent to which health promotion efforts after the completion of acute treatment attend to the needs of adult survivors and families is unclear. This systematic scoping review summarizes the key characteristics of post-treatment lifestyle interventions aiming to improve diet, physical activity, and/or weight-related outcomes for adult cancer survivors and family members.

METHODS

We retrieved relevant studies from six databases using keywords. Studies were appraised for quality and limited to English-language, peer-reviewed journal articles published in or after 2005.

RESULTS

A total of 2,376 articles were obtained from the databases; 14 main articles (and 2 supplemental articles) representing 14 unique interventions were retained for our analysis. Most interventions were designed to modify aspects of participant diet and physical activity (in combination) or physical activity alone; cited social cognitive theory as a guiding or interpretative framework; included survivors of multiple cancer types; and were limited to one type of familial relationship (e.g., spouse/partner, sister). Where reported, intervention samples were predominantly White.

CONCLUSIONS

Few post-treatment interventions concurrently target cancer survivor and family members' positive lifestyle behaviors. Positive findings highlight the potential for expanding this area of intervention research and increasing understanding of individual and familial factors that contribute to successful post-treatment family interventions.

IMPLICATIONS FOR CANCER SURVIVORS

Promoting cancer survivors' healthy behaviors within the family context could capitalize on existing support networks and improve the health of family members in supportive roles.

A Review of Web-Based Nutrition Information in Spanish for Cancer Patients and Survivors

Nutrition education resources are of interest for cancer patients and survivors throughout the cancer continuum. We examined the web-based nutrition information in Spanish for cancer patients and survivors provided by national cancer organizations (NCOs). The Guide to Internet Resources for Cancer and the membership list of the Union for International Cancer Control were searched to identify the NCOs. The International Patients Decisions Aid Standards (IPDAS) was used to describe the quality of the available information. We identified 20 NCOs that provided nutrition information aimed at a general audience on their websites. Web-based resources of nine NCOs were selected for presentation in this review. Website scores ranged between 20 and 24 in the IPDAS scale (maximum score = 31). The selected NCOs offered reliable and safe information. Healthy eating information for cancer patients and management of side-effects was provided by all websites. Information was more limited for cancer survivors. We recommend that NCOs increase the possibilities for personalized recommendations and interaction with the content by including instrumental tools on their websites.

Dietary and physical activity changes and adherence to WCRF/AICR cancer prevention recommendations following a remotely delivered weight loss intervention for female breast cancer survivors: The Living Well after Breast Cancer randomized controlled trial

BACKGROUND

Diet, exercise, and weight management are key in improving outcomes for breast cancer survivors, with international recommendations for cancer survivors relating to these behaviors. However, few behavioral interventions have reported outcomes aligned specifically with these recommendations.

OBJECTIVE

To evaluate a remotely delivered weight loss intervention versus usual care for female breast cancer survivors, on changes in multiple diet and physical activity behaviors.

DESIGN

A randomized controlled trial with assessments at study baseline, 6-, 12- and 18 months (i.e., mid-intervention, post-intervention, and non-contact follow-up).

PARTICIPANTS/SETTING

Participants were recruited between October 2012 and December 2014 through hospitals in Brisbane (Australia) and the state-based cancer registry. Eligible participants (female, 18-75 years, BMI 25-45 kg/m², diagnosed with stage I-III breast cancer in previous two years) were randomly allocated to intervention (n=79) or usual care (n=80).

INTERVENTION

Participants randomized to the intervention group received 22 counseling telephone calls targeting diet and physical activity aimed at achieving 5-10% weight loss, and optional text messages, over 12 months. Usual care participants received their standard medical care and brief feedback following each assessment, which was similar to that provided to intervention participants with the exception that usual care participants' results were not compared to national and study recommendations.

MAIN OUTCOME MEASURES

Dietary intake (24-hour recalls); physical activity (hip-worn Actigraph); sitting time (thigh-worn activPAL3); and, adherence to World Cancer Research Fund/American Cancer Research Institute (WCRF/AICR) recommendations for cancer survivors (0-7 score) were measured at each assessment, with data collected between November 2012 and October 2016.

STATISTICAL ANALYSES PERFORMED

Intervention effects were assessed by linear mixed models, accounting for repeated measures and baseline values. Significance was set at P<0.05.

RESULTS

At baseline, participants were (mean±SD) aged 55±9 years, with a BMI of 31.4±5.0 kg/m², 10.7±5.0 months post-diagnosis, and primarily non-minority. At baseline, only 8% (n=12) of participants met ≥5/7 WCRF/AICR recommendations (mean±SD WCRF/AICR adherence score: 3.8±1.0). At 12 months, significant intervention effects were observed in walking/running ( +21 mins/week; 95%CI: 4, 38) and WCRF/AICR adherence scores (+0.3 points; 95%CI: 0.0, 0.6) only. At 18 months, significant intervention effects were observed for energy intake (-229 kcal/day energy; 95%CI: -373, -84), total fat (-10 g/day; 95%CI: -18, -2), and saturated fat (-5 g/day; 95%CI: -9, -1), and were sustained for WCRF/AICR adherence scores (+0.5 points; 95%CI: 0.2, 0.8).

CONCLUSIONS

This remotely delivered weight loss intervention led to sustained improvements in WCRF/AICR adherence scores, and some improvements in diet and physical activity. These findings provide support for the health benefit of programs targeting lifestyle behaviors in line with cancer survivor recommendations, and the potential for dissemination of such programs following treatment for early-stage female breast cancer.

Limited Changes in Lifestyle Behaviours after Non-Muscle Invasive Bladder Cancer Diagnosis

The aim of our study was to investigate adherence to lifestyle recommendations and lifestyle changes after diagnosis in patients with non-muscle invasive bladder cancer (NMIBC). Second, we aimed to identify distinct trajectories of lifestyle change and their correlates. We analysed data of 935 patients with NMIBC from a prospective cohort study at six weeks (evaluating pre-diagnostic lifestyle), three months, and fifteen months after diagnosis. An overall lifestyle score (range 0-7) was calculated based on the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) recommendations focusing on diet, body mass index, and physical activity. Linear mixed models were used to analyse absolute lifestyle changes over time. Distinct trajectories of change were identified with latent class trajectory models. We found an overall lifestyle score of 3.3 which remained constant over time. The largest lifestyle changes were observed for the consumption of red and processed meat (-96 g/week) and fruit and vegetables (-38 g/day). Two to four trajectory groups were identified for each single lifestyle behaviour. Correlates differed per trajectory group. In conclusion, adherence to the WCRF/AICR recommendations was low. Small to moderate changes in and different trajectories of single lifestyle behaviours were observed. Effective strategies for lifestyle improvement are warranted.

Considerations of Control Conditions Designs in Randomized Controlled Trials of Exercise Interventions for Cancer Survivors

Background

Given the multifaceted complexity in the nature of randomized controlled trials, identifying an appropriate and comparable control condition is an essential step to ensure methodological rigor, which allows for researchers to draw unambiguous conclusions concerning the efficacy of the intervention being studied.

Objectives

The objectives of this paper are to (a) review the current literature and analyze the control condition designs in exercise interventions targeted for cancer survivors; (b) provide an overview of the benefits and limitations of various types of control conditions used in exercise interventions; (c) discuss the considerations in the design of control conditions for exercise interventions; and (d) suggest recommendations for control condition design in future trials of behavioral interventions.

Results

The review of randomized controlled trials of exercise training interventions for cancer survivors revealed that the design of control conditions varied. The most commonly employed design could be classified into two major categories: (a) active controls including attention control, add-on controls, and dismantling controls; and (b) inactive controls including no-treatment, usual care, and wait-list control. Examples from the literature are presented. Four principal considerations concerning control condition design, including appropriateness, credibility, appeal, and comparability, are discussed. Recommendations on how to avoid some major threats to validity and potential biases are also provided.

Conclusions

Careful planning for the control group design is as important as for the intervention group. Researchers can use the considerations presented in the paper to assist in planning for the most appropriate control condition for their study.

Association between Fruit and Vegetable Intake and Physical Activity among Breast Cancer Survivors: A Longitudinal Study

This study examines the association between rates of change in daily fruit and vegetable intake and in weekly levels of moderate-to-vigorous intensity physical activity (MVPA) over a 15-month period in women following primary treatment completion for breast cancer. Breast cancer survivors (N = 199) self-reported fruit and vegetable intake and wore an accelerometer for 7 consecutive days to measure levels of MVPA on five occasions every 3 months. Multivariate latent growth modeling revealed that the rate of change in fruit and vegetable intake was not associated with the rate of change in levels of MVPA. Baseline (Mean = 3.46 months post-treatment) levels of MVPA were not associated with the rate of change of daily fruit and vegetable intake; likewise, baseline fruit and vegetable intake was not associated with the rate of change in levels of MVPA. Behavioral interventions promoting fruit and vegetable intake should not be assumed to yield concomitant effects in promoting MVPA or vice versa.

Modified WCRF/AICR Score and All-Cause, Digestive System, Cardiovascular, Cancer and Other-Cause-Related Mortality: A Competing Risk Analysis of Two Cohort Studies Conducted in Southern Italy

Background: In real life, nutrition goes beyond purely biological domains. Primary prevention is the most efficient approach for reducing the risk of mortality. We aimed to study the association of lifestyle, as measured by a modified World Cancer Research Fund/American Institute for Cancer Research (mWCRF/AICR) scoring system with all-cause, digestive system disease-related (DSD-related), cardiovascular disease-related (CVD-related), cancer–related and other cause-related mortality using data from two population-based cohort studies conducted in Southern Italy. Methods: A random sample of 5271 subjects aged 18 years or older was enrolled in 2005–2006 and followed up until 2020. Usual food intakes were estimated using a validated dietary questionnaire. Competing risks survival models were applied. Results: High adherence to the mWCRF/AICR score was found to be statistically significant and negatively associated with all-cause mortality (HR 0.56, 95%CI 0.39; 0.82), DSD-related mortality (SHR 0.38, 95%CI 0.15; 0.97) and cancer-related mortality (SHR 0.43, 95%CI 0.19; 0.97) in the male sub-cohort and other-cause mortality (SHR 0.43, 95%CI 0.21; 0.88) only in the female group. Conclusions: This mWCRF/AICR score can be seen as a simple, easy tool for use in clinical practice to evaluate both qualitative and quantitative aspects of the diet.

Health-Promoting Lifestyle in Colorectal Cancer Survivors: A Qualitative Study on the Experiences and Perspectives of Colorectal Cancer Survivors and Healthcare Providers

OBJECTIVE

Understanding the experiences of survivors and healthcare providers about health-promoting lifestyle (HPL) in colorectal cancer (CRC) survivors is important in planning for coping with the disease, managing treatment side effects, increasing survival, and improving quality of life (QOL). This study was conducted to explore the experiences and perspectives of CRC survivors and healthcare providers about HPL in CRC survivors.

METHODS

This descriptive qualitative study was performed in 2020 at Omid and Imam Reza Hospitals in Mashhad, Iran. Participants were CRC survivors (n = 12) and healthcare providers (n = 33) who were selected by purposive sampling. Data were collected using in-depth semi-structured interview by face to face and then analyzed by Zhang and Wildemuth content analysis method. MaxQDA software was used to organize the data.

RESULTS

Following the treatment of cancer, CRC survivors seek to make changes in lifestyle and they choose a HPL that maintains or improves their health. HPL in CRC survivors includes nutrition, activity and rest, health responsibility, interpersonal relations, spiritual growth, and psychological management. The results showed that HPL can lead to motivation, the ability to self-care and improve daily performance, reduce treatment complications, and increase the QOL.

CONCLUSIONS

CRC survivors can help change their lifestyle patterns with healthy eating, treatment adherence, regular physical activity, and good sleep habits. Furthermore, effective personal and social relationships, spiritual growth, and management of psychological disorders develop health-promoting behaviors in them. CRC survivors also face challenges and limitations in their life after treatment; identifying the components of a HPL in CRC survivors can lead to desirable care, treatment, education, and counseling services.

Physical Activity Interventions for Colorectal Cancer Survivors: A Systematic Review and Meta-analysis of Randomized Controlled Trials

Background

Physical activity (PA) has been shown to improve total mortality and colorectal-specific mortality risk; however, colorectal cancer (CRC) survivors have lower rates of PA compared with survivors with other types of cancers.

Objective

To examine the effect of PA interventions on CRC survivors.

Methods

A systematic review and meta-analysis were conducted to identify randomized controlled trials that met the inclusion criteria, which included an intervention designed to increase PA and more than 1 outcome of interest. Random effects of the meta-analyses were performed using Review Manager 5.3.

Results

Eight publications representing 7 randomized controlled trials of 803 participants were identified. All studies used a combination of behavioral change methods. Physical activity interventions significantly improved disease-specific quality of life, PA level, and maximum amount of oxygen and did not show significant improvements for fatigue and body mass index among CRC survivors.

Conclusions

We provided evidence that PA interventions were effective in improving disease-specific quality of life, PA level, and maximum amount of oxygen; however, they did not improve fatigue and body mass index. Further randomized controlled trials are needed to determine the optimal mode of delivering PA intervention for CRC survivors.

Implications for Practice

As the survival rate of patients with CRC increases, survivors of CRC need to increase PA in a community setting after completing primary treatments. Effective and efficient modes of PA intervention delivery could improve health-related outcomes and address specific barriers for CRC survivors.

Diet Changes and Underlying Motives in Cancer Patients

With rising cancer incidence rates and numbers of long-term cancer survivors, diet increasingly comes into view of patients as well as healthcare providers. The aim was to analyze cancer patients' concepts of nutrition, changes in diet and reasons for these changes. This study is a cross-sectional single-center study. Data was collected 12/2017 - 01/2019 using a questionnaire. The study was set at an outpatient department at a German university hospital. 102 patients (male n = 47, female n = 54; age 34 to 86 years [mean = 62.3]) with cancer were included in the study. Statistical calculation was performed with Mann-Whitney-U-Test and Wilcoxon-signed-rank. p < 0.05 was considered significant. Patients were more concerned with diet after their diagnosis than before (p < 0.01). Seventy-one (70%) patients reported that they changed their diet or planned to do so. Some changes included an increased intake of vegetables or fruits. Patients who changed their diet more often were convinced that there was a positive influence of diet on the course of cancer (p < 0.05). Diet is an important topic for many cancer patients. Some patients seem to have a lack of information regarding the effect of diet on health. Physicians and dietitians should provide more education on healthy and safe diets for cancer patients.

Feasibility, acceptability, and effects of behavior change interventions for improving multiple dietary behaviors among cancer survivors: a systematic review

OBJECTIVE

This study aimed to systematically identify and synthesize evidence on the feasibility, acceptability, and effects of behavior change interventions for improving multiple dietary behaviors among cancer survivors.

METHODS

A total of 14 electronic databases and three trial registries were searched. Experimental studies that examined the feasibility, acceptability, and effects of behavior change interventions for improving multiple dietary behaviors among cancer survivors and published in English or Chinese peer-reviewed journals or protocols were considered eligible. The methodological quality of the included studies was evaluated using the revised Cochrane risk-of-bias assessment tool. Data were extracted and synthesized narratively.

RESULTS

Six studies, with a sample size ranging from 50 to 3088, were included. The studies had a high overall risk of bias. Six studies reported feasibility data, and the average eligibility, recruitment, and retention rates at post-intervention were 60.7%, 66.7%, and 90.7%, respectively. Only one study measured the acceptability and reported that 66.6% of participants were satisfied with the intervention. Five out of the six studies that measured fruit and vegetable consumption reported statistically significant positive intervention effects. Two studies reported inconsistent intervention effects on wholegrain consumption. Only one study measured the consumption of processed meat, sugar, and alcohol, which had statistically nonsignificant intervention effect.

CONCLUSIONS

Behavior change interventions for improving multiple dietary behaviors might be feasible and effective to increase fruit and/or vegetable consumption among cancer survivors. Further research is needed to examine the acceptability and effects of the intervention for modifying other dietary behavior.

Perceptions of e-cigarette harm among cancer survivors: Findings from a nationally representative survey

BACKGROUND

The growth in e-cigarette use may be driven by the perception that they are a safer, healthier alternative to conventional cigarettes. However, their long-term health implications are not well known and use is discouraged by most cancer societies. It is currently unclear how cancer survivors perceive the risks associated with e-cigarette and how this may influence use in this population.

METHODS

A cross-sectional analysis was conducted using the Health Information National Trends Survey (HINTS) (Years 2017-2019). Our primary study outcome was the perception of harm associated with e-cigarettes compared to traditional cigarettes among adults with and without a self-reported history of cancer. We used logistic regression analyses assessing the association of a cancer history with the perception that e-cigarettes are as much or more harmful than cigarettes.

RESULTS

A total of 11,846 respondents (weighted population estimate 243,728,483) were included. Of these, 26.6% reported a history of cancer. The proportion of cancer survivors who perceived e-cigarettes to be as much or more harmful than conventional cigarettes was similar to non-cancer respondents (70.6% vs 68.3%, P = 0.35). There was no difference in perception of harm among cancer and non-cancer respondents, adjusted for sociodemographic factors (OR 0.82, 95% CI 0.6-1.1). Past (OR 9.06, 95% Cl 5.06-16.20) and never e-cigarette use (OR 23.40, 95% Cl 13.56-40.38) as well as having a history of cardiopulmonary disease (OR 1.28, 95% Cl 1.05-1.56) was associated with higher odds of perceiving e-cigarettes to be as much or more harmful.

CONCLUSION

Cancer survivors commonly perceive e-cigarettes to be as much or more harmful than traditional cigarettes though these findings are similar to perceptions among adults without a history of cancer. There is a strong association with avoidance of e-cigarette products among those who perceive them to be harmful.

Relationship Between Individual Health Beliefs and Fruit and Vegetable Intake and Physical Activity Among Cancer Survivors: Results from the Health Information National Trends Survey

Purpose: The aim of this study was to describe diet and physical activity (PA) behaviors and health beliefs among cancer survivors and identify potential differences between adolescent and young adult (AYA) and adult/older cancer survivors. Methods: Cancer survivors (n = 1864) participating in the Health Information National Trends Survey (HINTS) provided responses regarding diet and PA and selected health beliefs related to general health and cancer (self-efficacy, attitudinal belief, normative belief, risk belief, intention, and self-regulation). Health belief associations with diet and PA were assessed using adjusted logistic regression models, and multiple linear regression was used for a computed Modified American Cancer Society Adherence score (0-10, higher score indicates higher adherence to recommendations); age at diagnosis was evaluated as a potential effect modifier. Results: Health behaviors between AYA and adult/older were not significantly different; a greater percent of AYA met fruit and resistance PA recommendations. Higher health self-efficacy was associated with meeting aerobic PA recommendations (odds ratio [OR]: 1.71; confidence interval [95% CI]: 1.13-2.60; p = 0.01). Higher intention was inversely related to meeting vegetable recommendation (OR: 0.58; 95% CI: 0.35-0.97; p = 0.04). Self-regulation was associated with higher odds of meeting each recommendation. Self-efficacy and self-regulation were associated with greater adherence (β = 0.52 ± 0.16, p = 0.001; β = 1.21 ± 0.24, p < 0.0001, respectively). Age at diagnosis was not an effect modifier. Conclusion: Health behaviors and beliefs among AYA and adult/older are similar. Self-efficacy and self-regulation through engagement with a mobile app support adoption of diet and PA recommendations among HINTS respondents. Future interventions should consider mechanisms to promote self-efficacy and self-regulation to maximize diet and PA behaviors in cancer survivors.

Readdressing the Needs of Cancer Survivors During COVID-19: A Path Forward

The growing number of cancer survivors and the high prevalence of cancer-related physical and psychosocial effects pose important and pressing challenges to health systems. The coronavirus disease 2019 (COVID-19) pandemic has led to further stressors on cancer survivors and health care systems. As the pandemic continues to have substantial impact on the world, it is critical to focus attention on the health care needs of cancer survivors. In this commentary, we propose an adoption of essential steps that should be part of a continuous adaptive approach to promote effective cancer survivorship care during ongoing COVID-19 waves and beyond.

Evolution of physical activity and body weight changes in breast cancer survivors five years after diagnosis - VICAN 2 & 5 French national surveys

Background

Regular physical activity (PA) and healthy body weight have proven benefits on survival in breast cancer (BC) survivors. We aimed to define predictors of long-term PA and weight gain in a representative sample of BC survivors.

Methods

Data were analysed from 723 women with BC who participated in both the 2012 and 2015 French National VICAN surveys.

Results

Five years after diagnosis, 26.0, 60.6, and 13.4 % of BC survivors reported regular, occasional and no PA, respectively. Moreover, 27.4 % had a weight gain ≥5 kg. In multinomial logistic regressions, regular and occasional PA were both associated with not having depressive disorders, with higher post-traumatic growth, and with a healthy and stable Body Mass Index. Occasional PA was associated with the use of non-conventional medicine, and regular PA with better mental quality of life and normal arm mobility. Weight gain ≥5 kg was associated with younger age, heavier body weight at diagnosis, and lymphedema 5 years after diagnosis.

Conclusions

Mental well-being is associated with successful long-term patient investment in PA. Psychological support and early management of disease sequelae are needed to help ensure BC survivors engage in and maintain healthy lifestyles.

•

A quarter of breast cancer survivors at 5 years reported regular physical activity.

•

Occasional physical activity was associated with use of non-conventional medicine.

•

Mental well-being was associated with long-term investment in physical activity.

•

Early sequelae managing may help survivors engage in and maintain healthy lifestyles.
