Age- and treatment-related associations with health behavior change among breast cancer survivors

The Relationship Between the Number of Chronic Diseases and Health-Related Quality of Life Among Middle-Aged and Older Adults in Rural Areas of Yunnan Province, China: moderating Effect of Health Lifestyle

Purpose

With population aging, individuals in underdeveloped areas may experience a higher prevalence of chronic non-communicable diseases (NCDs), a lower level of health-related quality of life (HRQoL), and distinct lifestyles. However, this triadic association remains inadequately studied, particularly regarding the role of health lifestyle. This study aims to examine the relationship between the number of NCDs and HRQoL, while considering the moderating effect of health lifestyle among middle-aged and older adults residing in resource-limited areas.

Methods

This cross-sectional study was conducted in Yunnan Province from July to December 2022. Participants completed a self-report questionnaire related to socio-demographic information, NCDs conditions, health lifestyle status, and HRQoL, which was assessed using the EuroQol five-dimension five-level (EQ-5D-5L) scale. Hierarchical regression and simple slope tests were used to examine the moderating effect of health lifestyle.

Results

Out of the total 2704 participants, 57.91% presented at least one NCD. The mean scores for health lifestyle and health utility value were 11.109 and 0.944 respectively. The number of NCDs was negatively associated with health utility value, while positively correlated with the health lifestyle score (P<0.001). The results of hierarchical regression indicated that health lifestyle exerted a negative moderating effect on the relationship between the number of NCDs and HRQoL (β=0.006, P<0.001), which was also observed for specific health-related behaviors such as sleep duration (β=0.013, P<0.001), physical examination attendance (β=0.006, P<0.05) and physical activity (β=0.013, P<0.001).

Conclusion

These findings highlight the crucial role of a healthy lifestyle in attenuating the association between the number of NCDs and HRQoL. Recognizing the potential modulating influence of a healthy lifestyle in this relationship could be pivotal for developing effective interventions for this population, even within resource-constrained rural settings.

Health-promoting behaviours and psychological distress in breast cancer with endocrine therapy: Mediating roles of menopausal symptoms and social support

OBJECTIVE

To investigate the relationship between health-promotion behaviour and psychological distress and whether menopausal symptoms and social support mediate these relationships in patients with breast cancer receiving endocrine therapy.

STUDY DESIGN

This was a cross-sectional study involving convenience sampling that involved 226 patients with breast cancer.

MAIN OUTCOME MEASURES

Participants were investigated by self-reporting questionnaires that included demographic and clinical information, the Kessler psychological distress scale, the Health-Promoting Lifestyle Profile Ⅱ, the Menopause Rating Scale, and the Perceived Social Support Survey to measure psychological distress, health-promoting behaviour, menopausal symptoms, and social support, respectively. Mediation analyses were conducted with the bootstrapping method to test for mediating factors.

RESULTS

In total, 78.7% patients reported that they were suffering from psychological distress. Their health-promoting behaviours were directly and negatively associated with psychological distress. In addition, health-promoting behaviour had a significant indirect effect on psychological distress through menopausal symptoms and social support. Mediating effects accounted for 34.8% and 27.6% of the total effect, respectively.

CONCLUSIONS

There was a high prevalence of psychological distress in patients with breast cancer receiving endocrine therapy. Menopausal symptoms and social support mediated the association between health-promoting behaviour and psychological distress. Health professionals should evaluate menopausal symptoms and health lifestyles, and provide professional interventions to increase health-promoting behaviours and manage unpleasant somatic symptoms for patients and their caregivers; these actions may improve their psychological distress.

The Practice of Physical Activity After Breast Cancer Treatments: A Qualitative Study Among Portuguese Women

Background

Women survivors of breast cancer treatments face significant challenges around initiation or maintenance of physical activity (PA) as they transit to recovery. Embracing their needs and preferences is important to increase adherence. This study aimed to explore the perspectives of Portuguese women survivors of breast cancer regarding regular performance of PA and individual choices and strategies that should be considered in designing effective interventions.

Methods

The individual semi-structured interviews (N = 20) were analyzed through thematic analysis, following an inductive process, seeking to identify the barriers, facilitators, and particular influencing circumstances associated with regular PA.

Results

Four themes and several contextual, emotional, physical, and social factors were identified as determinants of regular PA. Guilt, women’s duties, and altruism to help close relatives were identified as emotional and cultural factors that are less-found in the existing literature. PA showed influence both from health professionals’ counseling and from knowledge and beliefs held by these women.

Conclusion

While confirming the already-known impact of breast cancer diagnosis and treatments on PA, which redefine participants’ availability to be active, the findings highlight beliefs and specific emotional factors that should be considered when planning culturally sensitive interventions.

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.

High Prediagnosis Inflammation-Related Risk Score Associated with Decreased Ovarian Cancer Survival

BACKGROUND

There is suggestive evidence that inflammation is related to ovarian cancer survival. However, more research is needed to identify inflammation-related factors that are associated with ovarian cancer survival and to determine their combined effects.

METHODS

This analysis used pooled data on 8,147 women with invasive epithelial ovarian cancer from the Ovarian Cancer Association Consortium. The prediagnosis inflammation-related exposures of interest included alcohol use; aspirin use; other nonsteroidal anti-inflammatory drug use; body mass index; environmental tobacco smoke exposure; history of pelvic inflammatory disease, polycystic ovarian syndrome, and endometriosis; menopausal hormone therapy use; physical inactivity; smoking status; and talc use. Using Cox proportional hazards models, the relationship between each exposure and survival was assessed in 50% of the data. A weighted inflammation-related risk score (IRRS) was developed, and its association with survival was assessed using Cox proportional hazards models in the remaining 50% of the data.

RESULTS

There was a statistically significant trend of increasing risk of death per quartile of the IRRS [HR = 1.09; 95% confidence interval (CI), 1.03-1.14]. Women in the upper quartile of the IRRS had a 31% higher death rate compared with the lowest quartile (95% CI, 1.11-1.54).

CONCLUSIONS

A higher prediagnosis IRRS was associated with an increased mortality risk after an ovarian cancer diagnosis. Further investigation is warranted to evaluate whether postdiagnosis exposures are also associated with survival.

IMPACT

Given that pre- and postdiagnosis exposures are often correlated and many are modifiable, our study results can ultimately motivate the development of behavioral recommendations to enhance survival among patients with ovarian cancer.

Alcohol Consumption: Discussing Potential Risks for Informed Decisions in Breast Cancer Survivors

BACKGROUND

Alcohol consumption is a known risk factor for breast cancer. Because breast cancer survivors are already at risk for recurrence, it is important to understand whether these survivors could benefit from survivor-specific recommendations for alcohol consumption.

OBJECTIVES

The purpose of this article was to review primary research specific to alcohol and breast cancer survivors to see whether those who consume alcohol experience more adverse effects.

METHODS

This literature review examined nine cohort studies specific to breast cancer survivors, alcohol consumption, and risks for breast cancer recurrence, breast cancer-specific mortality, and second primary breast cancers.

FINDINGS

Current guideline recommendations of a safe limit of one drink per day or less may not protect breast cancer survivors from cancer- related adverse events. The authors recommend that breast cancer survivors be educated about the associated risks of alcohol consumption so that they can make informed decisions about usage.

Association of First Primary Cancer With Risk of Subsequent Primary Cancer Among Survivors of Adult-Onset Cancers in the United States

IMPORTANCE

The number of cancer survivors who develop new cancers is projected to increase, but comprehensive data on the risk of subsequent primary cancers (SPCs) among survivors of adult-onset cancers are limited.

OBJECTIVE

To quantify the overall and cancer type-specific risks of SPCs among adult-onset cancer survivors by first primary cancer (FPC) types and sex.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective cohort study from 12 Surveillance, Epidemiology, and End Results registries in the United States, that included 1 537 101 persons aged 20 to 84 years diagnosed with FPCs from 1992-2011 (followed up until December 31, 2017) and who survived at least 5 years.

EXPOSURES

First primary cancer.

MAIN OUTCOMES AND MEASURES

Incidence and mortality of SPCs per 10 000 person-years; standardized incidence ratio (SIR) and standardized mortality ratio (SMR) compared with those expected in the general population.

RESULTS

Among 1 537 101 survivors (mean age, 60.4 years; 48.8% women), 156 442 SPC cases and 88 818 SPC deaths occurred during 11 197 890 person-years of follow-up (mean, 7.3 years). Among men, the overall risk of developing any SPCs was statistically significantly higher for 18 of the 30 FPC types, and risk of dying from any SPCs was statistically significantly higher for 27 of 30 FPC types as compared with risks in the general population. Among women, the overall risk of developing any SPCs was statistically significantly higher for 21 of the 31 FPC types, and risk of dying from any SPCs was statistically significantly higher for 28 of 31 FPC types as compared with risks in the general population. The highest overall SIR and SMR were estimated among survivors of laryngeal cancer (SIR, 1.75 [95% CI, 1.68-1.83]; incidence, 373 per 10 000 person-years) and gallbladder cancer (SMR, 3.82 [95% CI, 3.31-4.39]; mortality, 341 per 10 000 person-years) among men, and among survivors of laryngeal cancer (SIR, 2.48 [95% CI, 2.27-2.72]; incidence, 336 per 10 000 person-years; SMR, 4.56 [95% CI, 4.11-5.06]; mortality, 268 per 10 000 person-years) among women. Substantial variation existed in the associations of specific types of FPCs with specific types of SPC risk; however, only a few smoking- or obesity-associated SPCs, such as lung, urinary bladder, oral cavity/pharynx, colorectal, pancreatic, uterine corpus, and liver cancers constituted considerable proportions of the total incidence and mortality, with lung cancer alone accounting for 31% to 33% of mortality from all SPCs.

CONCLUSIONS AND RELEVANCE

Among survivors of adult-onset cancers in the United States, several types of primary cancer were significantly associated with greater risk of developing and dying from an SPC, compared with the general population. Cancers associated with smoking or obesity comprised substantial proportions of overall SPC incidence and mortality among all survivors and highlight the importance of ongoing surveillance and efforts to prevent new cancers among survivors.

Changes in alcohol consumption, body weight and physical activity among breast cancer survivors and population-based unaffected women in a prospective study

BACKGROUND

It is unclear whether a breast cancer diagnosis affects health behaviour changes that occur with ageing. We aimed to compare long-term changes of alcohol consumption, body weight, and physical activity in women with breast cancer and in age-matched unaffected women.

METHODS

We used data from 1,925 women with breast cancer and 3,473 unaffected women aged 50-74 years enrolled in the population-based case-control study MARIE (Mamma Carcinoma Risk Factor Investigation) in 2002-2005, who also completed the follow-up in 2014-2016. Multinomial logistic regression was applied to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) for the associations between breast cancer status and categories of change in alcohol consumption, weight and physical activity.

RESULTS

After 11.6 years of follow-up, breast cancer survivors had significantly lower odds than unaffected women of increasing alcohol consumption from ≤10 to >10 g/day (adjusted OR 0.48, 95 % CI 0.35-0.65), but were more likely to experience a major weight change of ≥10 % compared to having stable weight (±<5 %) (OR for increase and decrease 1.32, 95 % CI 1.03-1.70 and 1.36, 95 % CI 1.05-1.77, resp.) and to decrease transport physical activity to below 2.5 h/week compared to maintaining the activity level (OR 1.61, 95 % CI 1.26-2.04). No significant group difference was found for changes in recreational physical activity.

CONCLUSION

Our data indicate that some long-term health behaviour changes can be attributed to a breast cancer diagnosis rather than ageing, suggesting that long-term medical care of breast cancer survivors could pay greater attention to weight control and sufficient physical activity.

Long-term anti-inflammatory diet in relation to improved breast cancer prognosis: a prospective cohort study

Inflammation-modulating nutrients and inflammatory markers are established cancer risk factors, however, evidence regarding the association between post-diagnosis diet-associated inflammation and breast cancer survival is relatively sparse. We aimed to examine the association between post-diagnosis dietary inflammatory index (DII®) and risks of all-cause and breast cancer-specific mortality. A total of 1064 female breast cancer survivors in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening (PLCO) Trial prospective cohort, were included in this analysis if they had completed the diet history questionnaire (DHQ). Energy-adjusted DII (E-DIITM) scores were calculated based on food and supplement intake. Cox regression and competing risk models were used to estimate multivariable-adjusted hazards ratios (HRs) and 95% confidence intervals (95% CIs) by E-DII tertile (T) for all-cause and breast cancer-specific mortality. With median follow-up of 14.6 years, there were 296 (27.8%) deaths from all causes and 100 (9.4%) breast cancer-specific death. The E-DII was associated with all-cause mortality (HR T3 vs T1, 1.34; 95% CI, 1.01-1.81; P trend, 0.049, Table 2) and breast cancer mortality (HR T3 vs T1, 1.47; 95% CI, 0.89-2.43; P trend, 0.13; multivariable-adjusted HR for 1-unit increment: 1.10; 95% CI: 1.00-1.22). Non-linear positive dose-response associations with mortality from all causes were identified for E-DII scores (P non-linearity < 0.05). The post-diagnosis E-DII was statistically significantly associated with mortality risk among breast cancer survivors. Long-term anti-inflammatory diet might be a means of improving survival of breast cancer survivors.

The impact of smoking on adjuvant breast cancer radiation treatment: A systematic review

BACKGROUND

The influence of cigarette smoking on cancer risk has been well-studied. Similarly, exposure to ionizing radiation from radiotherapy (RT) can produce detrimental effects on an individual's health. In patients administered RT, there has been an observed relationship in other primary carcinomas. The purpose of this systematic review was to summarize the influence of cigarette smoking on outcomes post adjuvant RT in breast cancer patients.

METHODS

OVID Medline, Cochrane and Embase were searched and 1893 articles were identified. A total of 71 articles were included in the review. Study type, published year and sample size, age, systemic therapies, RT techniques and treatment side effects were collected if available.

RESULTS

The review found 198 different outcomes which fell into 7 categories and similar outcomes were recorded. 40% of skin reaction outcomes, 50% of cardiovascular outcomes, 71% of reconstruction outcomes, 29% of pulmonary function outcomes, 33% of mortality outcomes and 42% of secondary recurrence outcomes reported significant differences between smokers and non-smokers. None of the articles reported non-smokers to have a higher risk than smokers.

CONCLUSION

Cigarette smoking can pose a higher risk of post-treatment complications that can influence an individual's quality of life, survival rate and/or recurrence risk. This review further assessed the impact of smoking on various patient outcomes and side-effects in the adjuvant breast RT setting. The information provided in this review suggest that smoking cessation programs would help educate patients to understand their risks of being a current or former smoker when undergoing RT.

Multiple health behaviors before and after a cancer diagnosis among women: A repeated cross-sectional analysis over 15 years

Background

Cancer diagnosis may be a cue for health behavior change. Previous research that assessed the impact of a cancer diagnosis on multiple health behavior (MHB) change is limited by small sample size, cross‐sectional study design, and a focus on individual rather than multiple behaviors. This study investigated the impact of a cancer diagnosis on compliance with MHB recommendations.

Methods

Data from Australian Longitudinal Study on Women's Health (ALSWH) were utilized. Compliance with MHB was assessed by cancer survivorship period; 0‐3 years pre‐diagnosis, 0‐3 years postdiagnosis, 4‐12 years postdiagnosis, and compared to controls. A MHB score based on the WCRF/AICR guidelines was calculated for six behaviors (physical activity, smoking, alcohol, BMI, fruit, and vegetable intake); scores ranged from 0 to 6, with a higher score indicating higher compliance. Generalized estimating equation (GEE) was used for statistical analysis.

Results

Participants comprised 7585 women from the 2001 ALSWH survey, of whom 2285 developed cancer during 15 years of follow‐up. Compared to controls, the mean MHB score was slightly lower (Mean Difference (MD) = −0.015, P > .05) in survivors pre‐diagnosis, after adjusting for confounders; however, the compliance score increased during postdiagnosis, with the mean difference score being significantly higher in recent survivors (0‐3 years post diagnosis; MD = 0.055, P < .01). Likewise, within cancer survivors, the mean compliance score significantly increased 0‐3 years postdiagnosis (MD = 0.07, P < .05) compared to pre‐diagnosis, but this significant improvement was not maintained over the longer term (MD = 0.037, P > .05).

Conclusion

In this sample, survivors had higher MHB score than controls. A cancer diagnosis may provide a teachable moment for health behavior change in the period immediately following diagnosis, but this effect was not sustained during longer‐term survivorship.

Fertility-related experiences after breast cancer diagnosis in the Sister and Two Sister Studies

BACKGROUND

Commonly used chemotherapies can be toxic to the ovaries. To the authors' knowledge, the majority of studies evaluating receipt of fertility counseling for women in their reproductive years have been performed in specific settings, thereby limiting generalizability.

METHODS

A nationwide sample of US women diagnosed with breast cancer before age 45 years completed a survey assessing the prevalence of fertility counseling. Age-adjusted log-binomial regression was used to estimate prevalence ratios (PRs) and 95% CIs for fertility counseling.

RESULTS

Among 432 survivors diagnosed between 2004 and 2011, 288 (67%) had not discussed the effects of treatment on fertility with a health care provider before or during treatment. Fertility discussion was associated with younger age (PR, 3.49 [95% CI, 2.66-4.58] for aged <35 years vs ≥40 years) and lower parity (PR, 1.81 [95% CI, 1.29-2.53] for parity 1 vs 2). Approximately 20% of respondents reported that they were interested in future fertility (87 of 432 respondents) at the time of their diagnosis, but not all of these individuals (66 of 87 respondents) received counseling regarding the impact of treatment on their fertility, and few (8 of 87 respondents) used fertility preservation strategies. Among 68 women with a fertility interest who provided reasons for not taking steps to preserve fertility, reasons cited included concern for an adverse impact on cancer treatment (56%), lack of knowledge (26%), decision to not have a child (24%), and cost (18%).

CONCLUSIONS

Across multiple treatment settings, the majority of women of reproductive age who are diagnosed with breast cancer did not discuss fertility with a health care provider or use fertility preservation strategies. Discussing the potential impact of cancer treatment on future fertility is an important aspect of patient education.

Analysis of Health Behaviors and Personal Values of Childless Women, Pregnant Women and Women Who Recently Delivered

Preconception lifestyle modifications and reduction of several known risk factors may have an influence on future pregnancy outcomes. The aim of the study was to analyze health behaviors and personal values as well as to assess the relationship between these factors in women without children, in pregnant women and in women who had already delivered babies. The questionnaire survey included the Health Behavior Inventory (HBI), the Personal Value List (PVL) and sociodemographic data and was conducted in 538 women. These women were divided into three groups: women who had recently delivered (n = 235), pregnant women (n = 121) and childless women (n = 182). Pregnant women demonstrated a significantly higher level of declared health behaviors, and also, they rated higher on the subscales values “positive mental attitude” and “health practices”, in comparison to women who had recently delivered and to childless women. In all tested groups, the highest rated personal value was “a successful family life”, while the most appreciated symbol of happiness was “love and friendship”. Our results suggest that the system of values and the perception of happiness symbols may influence women’s health behaviors. Positioning “health” in the hierarchy of personal values as the most important one may facilitate the introduction of healthy behaviors. This, in turn, could reduce several adverse pregnancy outcomes that are potentially modifiable with changing preconception health attitudes. Our results also identify several unanswered questions and highlight areas where new research is needed.
