RESUMO
PURPOSE: Racial disparities in cardiovascular disease and cardiac dysfunction exist amongst breast cancer survivors. This study examined the prevalence of cardioprotective medication use in survivors and identified factors associated with use by race. METHODS: The analysis included women enrolled in the Women's Hormonal Initiation and Persistence study, a longitudinal observational trial of breast cancer survivors. The study outcome, angiotensin converting enzyme inhibitor (ACEi) or ß-Blocker (BB) use, were ascertained from pharmacy records. Demographic, psychosocial, healthcare, and quality of life factors were collected from surveys and clinical data were abstracted from medical records. Bivariate associations by race and ACEi/BB use were tested using chi square and t tests; logistic regression evaluated multivariable-adjusted associations. RESULTS: Of the 246 survivors in the sample, 33.3% were Black and most were < 65 years of age (58.4%). Most survivors were hypertensive (57.6%) and one-third received ACEi/BBs. In unadjusted analysis, White women (vs. Black) (OR 0.33, 95% 0.19-0.58) and women with higher ratings of functional wellbeing (OR 0.94, 95% 0.89-0.99) were less likely to use ACEi/BBs. Satisfaction with provider communication was only significant for White women. In multivariable-adjusted analysis, ACEi/BB use did not differ by race. Correlates of ACEi/BB use included hypertension among all women and older age for Black women only. CONCLUSIONS: After adjusting for age and comorbidities, no differences by race in ACEi/BB use were observed. Hypertension was a major contributor of ACEi/BB use in BC survivors.

Higher self-efficacy in receiving genetic counseling and testing (GCT) has been associated with greater participation in GCT for women at risk of hereditary breast and ovarian cancer (HBOC), but little is known about correlates of self-efficacy in Black women eligible for GCT. The goal of this secondary analysis was to identify sociodemographic and psychosocial factors regarding GCT. Multivariable regression analysis was conducted to assess the relationship between self-efficacy and correlates of interest. Of the 100 Black women surveyed, most women had a college degree (64%), were employed (84%), and had health insurance (93%). In the multivariable model, greater self-efficacy was associated with more positive attitudes toward GCT (Β = 0.126; CI = 0.01 to 0.25; p = 0.039), greater confidence in the Genetic Information Nondiscrimination Act (GINA) (Β = 0.250; CI = 0.04 to 0.46; p = 0.019), and lower ratings of perceived difficulty obtaining GCT (Β = -0.219; CI = -0.46 to -0.10; p = 0.003). Community-level interventions to promote self-efficacy are needed that address perceived barriers to GCT, with the goals of increasing GINA Law awareness in the general public, increasing accessibility to genetic counseling (e.g., telemedicine), and promoting more positive attitudes about GCT.

Previous studies have shown that breast cancer patients' beliefs regarding radiation therapy (RT) are influenced by a multitude of factors encompassing demographic, socioeconomic, cultural, and healthcare-related domains. The association between consultation with a multidisciplinary care team and breast cancer patients' attitudes towards RT, however, remains understudied. Using survey and medical record data from 185 women with invasive, non-metastatic breast cancer who received breast conserving surgery, we aimed to characterize the relationship between the number and type of oncological specialties consulted and women's belief in RT's ability to decrease the likelihood of breast cancer recurrence. Using multivariable models, we found that compared to women who discussed RT with only one oncologist (medical, radiation, or surgical), women who discussed RT with all three oncologists were more likely to report increased agreement with RT's ability to reduce cancer recurrence. No single specialty of oncology, including radiation oncology, showed increased associations with women's beliefs regarding RT's efficacy. We conclude that women's beliefs in the ability of radiation therapy to reduce breast cancer recurrence are associated with an increased number of oncologic physicians consulted.

Disparities in cancer screening and care in rural communities warrant the need to determine effective ways to reach, engage, and educate the community residents. The purpose of this cross-sectional study was to pilot methods to engage rural residents in colorectal cancer (CRC) research and education activities and assess knowledge of CRC guidelines, symptoms, and screening behaviors in this sample. The community-engaged research approach was employed to develop and distribute a CRC knowledge and screening behavior assessment using various methods such as email and community drop boxes placed throughout the community. Bivariate analysis assessed the relationship between age and CRC knowledge items. Three hundred ninety-one surveys were returned with most received from community drop boxes (60%) followed by educational events (23%). The most ineffective method to distribute surveys was through community events. Most individuals were knowledgeable of CRC symptoms (70%) and screening facts (67%). Bivariate analysis showed that individuals 50 years or older had significantly more knowledge of CRC risks and screening than those under the age of 50. This study highlights the potential of community drop boxes as an effective method for engaging rural communities. Further, findings from the survey highlight the need to focus CRC education on younger individuals in which CRC incidence has increased.

BACKGROUND: Physical activity (PA) is recommended for women with breast cancer (BC); however, data are sparse on the association of PA with quality of life (QOL) and patient-reported symptoms for women on adjuvant endocrine therapy (AET). METHODS: Women with hormone receptor-positive BC who were taking AET completed standardized surveys about their health-related QOL, AET-related symptoms, and levels of PA using validated measures. A Wald chi-square test and an analysis of variance were used to assess associations with PA and independent variables. Generalized linear regression analyses assessed associations between PA, QOL, and AET-related symptoms. RESULTS: The analytic cohort included 485 Black and White women. Black race, a high body mass index (BMI), and being on aromatase inhibitors (vs tamoxifen) were associated with lower PA in a bivariate analysis. In a multivariate analysis, lower self-reported PA was associated with a high BMI (P = .02) and chemotherapy uptake (P = .006). Better health-related QOL (P = .01), less severe overall AET-related symptoms (P = .02), and less severe gynecological symptoms (P = .03) were associated with increasing levels of moderate PA. CONCLUSIONS: Among women taking AET, moderate levels of PA may be associated with fewer medication-related symptoms and overall better ratings of health-related QOL. Because of the low levels of PA observed in the sample overall and particularly for Black women, identifying successful strategies to promote PA are needed.

PURPOSE: The last fifteen years has seen a rising proportion of women who are eligible for breast conserving therapy (BCT) choosing mastectomy despite equivalent survival in early-stage breast cancer. We aim to explore potential racial differences in the association of surgical choice with subsequent patient-reported satisfaction outcomes. METHODS: Women who were within one year of diagnosis with hormone receptor (HR)-positive breast cancer were asked the Short Version of Patient Satisfaction Questionnaire (PSQ-18), which assesses their overall satisfaction with their medical care. We conducted bivariate analyses, including paired t-tests, to clarify differences in these patient-reported factors by surgical choice and race. Multivariable linear regression models were used to adjust for clinical and demographic control variables. RESULTS: For the sample of 279 women who underwent definitive surgery, women who received a mastectomy had lower levels of overall satisfaction, 71 vs. 75 (out of 90) (p = .001). In stratifying this relationship by race, the difference in total satisfaction score was largest among Black women (69 among mastectomy patients vs. 75 among BCT patients; p = 0.016). On multivariable linear regression, Black race and mastectomy status (together) exhibited a significantly large negative association with total satisfaction score, with negative associations across all domains of the PSQ-18. CONCLUSION: Despite the high prevalence of mastectomy among Black women with early-stage, HR-positive breast cancer, this population is more likely to report lower levels of patient satisfaction compared to patients receiving BCT. These findings suggest there may be potential racial differences in the psychosocial consequences of surgical choice.

OBJECTIVE: Adjuvant endocrine therapy (AET) reduces the risk of recurrence and mortality in women with hormone receptor-positive breast cancer. However, adherence to AET remains suboptimal. Women's beliefs about medication have been associated with medication adherence. The purpose of this study was to identify multilevel factors associated with women's beliefs about AET. METHODS: Beliefs about AET, measured using the Belief about Medicines Questionnaire (BMQ), sociodemographic (e.g., age), psychosocial (e.g., religiosity), and healthcare factors (e.g., patient-provider communication), were collected via survey. Clinical data were abstracted from medical records. Two stepwise regression analyses models were performed to assess relationships between variables and necessity and concern beliefs. RESULTS: In our sample of 572 women, mean BMQ concern score was 11.19 and mean necessity score was 13.85 (range 5-20). In the regression models, higher ratings of patient-provider communication were associated with lower concern and higher necessity beliefs. Higher concern beliefs were related to more AET-related symptoms (Β = 0.08; 95% CI 0.06 to 0.10; p < 0.001), lower patient satisfaction (Β = - 0.07; 95% CI - 0.09 to - 0.04; p < 0.001), and higher religiosity (Β = 0.05; 95% CI 0.01 to 0.08; p = 0.007). Higher necessity beliefs were associated with prior chemotherapy use (Β = 0.11; 95% CI 0.06 to 0.16; p < 0.005) and less education (Β = 1.00; 95% CI 0.27 to 1.73; p = 0.008). CONCLUSIONS: Modifiable factors are related to women's AET beliefs. Healthcare interactions may play a key role with regard to shaping women's beliefs about their AET medication.

OBJECTIVE: To evaluate awareness and acceptability of population-based BRCA testing among an unselected population of women presenting for annual gynecologic health assessment, with secondary objective to determine if a racial disparity exists in acceptability and awareness of this screening strategy. METHODS: Women presenting for routine gynecologic care in an outpatient setting of a single academic institution were anonymously surveyed. Survey collected age, self-identified race and ethnicity, education level, personal and family history of breast and/or ovarian cancer (BOC), awareness and interest, and willingness to pay out of pocket for testing. Responses were compared with bivariate and multivariate analysis. RESULTS: Interest in testing was expressed in 150 of 301 (45.1%) of participants. Women with a family history of BOC were more likely to be interested in testing than those without (ORâ¯=â¯1.9 (1.0-3.6)). Interest in testing was associated willingness to pay (ORâ¯=â¯3.3 (1.7-6.4)). Higher education level was associated with awareness of testing (ORâ¯=â¯9.9 (2.0-49.7)). Interest in testing was similar between racial groups, but awareness and willingness to pay for testing were higher among White women. Multivariate analysis with adjustment for education level confirmed that Black and Hispanic women were less likely to have awareness of genetic testing compared to White women and non-Hispanic Women, respectively (ORâ¯=â¯0.11 (0.05-0.3); ORâ¯=â¯0.10 (0.01-0.8)). CONCLUSIONS: Interest in genetic testing among women in the general population is high. Despite interest, awareness of BRCA is poor among Black and Hispanic women even when adjusting for education level.

Medical mistrust measures have not been validated in Latino immigrants. This study examined the psychometric properties of the Medical Mistrust Index and its association with health care satisfaction in a sample of Latina immigrants. Participants were 168 self-identified Latinas ≥40 years old. Women were recruited from three Latino-serving health clinics and through a Latino radio program. A bilingual interviewer administered the Medical Mistrust Index in Spanish along with items pertaining to sociodemographic and health care factors. Principal component extraction method was used to evaluate internal consistency reliability to examine Medical Mistrust Index underlying factors. Construct validity was assessed by analyzing the relationship between the Medical Mistrust Index with three related measures (racism, discrimination, trust in doctors). To assess the criterion validity of the Medical Mistrust Index, a logistic regression model examined whether medical mistrust was associated with Latina women's satisfaction with health care controlling for sociodemographic and health care factors. Participants were 51 years old on average, around half had completed High school or less and were uninsured. Most were monolingual Spanish speakers. Two factors: competence and suspicion explained 40% of the total Medical Mistrust Index variance. Internal consistency was favorable and construct validity was supported. Results support the reliability and validity of the Medical Mistrust Index and its association with Latina's satisfaction with health care.

Studies indicate that Black patients report higher medical mistrust compared to their White counterparts. However, little is known about factors associated with higher medical mistrust among Black breast cancer patients. We examined predictors of medical mistrust and relationships between medical mistrust, subscales of mistrust, and process of care factors to identify opportunities to promote positive healthcare interactions between the trustees (e.g., providers) and Black breast cancer patients, or the trustors. A secondary analysis was conducted of survey data from 210 Black women with confirmed diagnosis of invasive breast cancer. Participants completed telephone surveys consisting of questions pertaining to sociodemographics, attitudes, and beliefs about medical care and breast cancer treatments. Multiple linear regression determined factors associated with medical mistrust and mistrust subscales. Most participants (61%) were over the age of 50 and currently single (64.8%). Women with greater medical mistrust reported less satisfaction with the trustee's technical ability (p < 0.0001) and greater satisfaction with their own propensity to access care (p < 0.05). Additionally, women with public insurance demonstrated greater mistrust (p < 0.01) and suspicion (p < 0.05) than women with private insurance, and women with less education reported greater perceived discrimination than women who have at least a bachelor's degree. Findings from this study may inform future endeavors to educate providers on ways to effectively interact with and treat Black breast cancer patients. Opportunities to develop interventions that address and tackle issues of mistrust as reported by Black patients may contribute to ongoing efforts to reduce health disparities.

Spirituality has been shown to be important to many individuals dealing with a cancer diagnosis. While African-American breast cancer survivors have been reported to have higher levels of spirituality compared to White women, little is known about how levels of spirituality may vary among African-American breast cancer survivors. The aims of this study were to examine factors associated with spirituality among African-American survivors and test whether spirituality levels were associated with women's attitudes about treatment or health care. The primary outcome, spirituality, was nine-item scale (Cronbach's α = .99). Participants completed standardized telephone interviews that captured sociocultural, healthcare process, and treatment attitudes. Medical records were abstracted post-adjuvant therapy for treatment and clinical information. In bivariate analysis, age was not correlated with spirituality (p = .40). Married/living as married women had higher levels of spirituality (m = 32.1) than single women (m = 30.1). Contextual factors that were associated with higher levels spirituality were: collectivism (r = .44; p < 0.0001, Afrocentric worldview (r = .185; p = .01), and self-efficacy scale (r = .17; p = .02). In multivariable analysis, sociodemographic factors were not significant. Collectivism remained a robust predictor (p < 0.0001). Attitudes about the efficacy of cancer treatment were not associated with spirituality. The high levels of spirituality in African-American survivors suggest consideration of integrating spiritual care within the delivery of cancer treatment. Future studies should consider how spirituality may contribute to positive coping and/or behaviors in African-American women with high levels of spirituality.

PURPOSE: Breast cancer survivors are at increased risk of cardiovascular dysfunction following their diagnosis; however, hypertension remains underexplored within this context. This retrospective cohort study examined the incidence of hypertension in breast cancer survivors and the association of race with hypertension risk among them. METHODS: Data for this study were abstracted from the electronic health records of women diagnosed with Stages I-III breast cancer. Incident hypertension diagnosis was identified through International Classification of Diseases codes. Bivariate associations were tested using Student's t-test and chi-squared test of independence. Bivariable Cox regression analysis was used to determine demographic and clinical factors that may have been associated with the development of hypertension. RESULTS: A total of 664 women were included. Most women were 50 years of age or younger (52.0%), White (33.0% Black), and received a mastectomy (80.6%). Overall, 45.5% of the cohort developed hypertension. The 1-year hypertension-free survival estimates were 47% (95% confidence interval [CI], 41-54) in Black women and 73% (95% CI, 69-77) in White women (p < 0.0001). Besides race, statistically significant predictors of hypertension included: age greater than 50 (vs. ≤50) (adjusted Hazard Ratio [HR]: 1.40; 95% CI, 1.09-1.80) and residing in a non-metropolitan area (vs. metropolitan) (adjusted HR: 1.60; 95% CI, 1.19-2.16). CONCLUSIONS: This study suggests that breast cancer survivors who are older, Black, or residing in non-metropolitan areas may benefit from added surveillance and hypertension prevention strategies during treatment. Future studies are needed to identify contributors to the observed racial and geographic disparities.

RESUMO
BACKGROUND: Lower income is associated with high incident cardiovascular disease (CVD) and mortality. CVD is an important cause of morbidity and mortality in cancer survivors. However, there is limited research on the association between income, CVD, and mortality in this population. METHODS: This study utilized nationally representative data from the National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey evaluating the health and nutritional status of the US population. Our study included NHANES participants aged ≥20 years from 2003-2014, who self-reported a history of cancer. We evaluated the association between income level, prevalence of CVD, and all-cause mortality. All-cause mortality data was obtained through public use mortality files. Income level was assessed by poverty-income ratio (PIR) that was calculated by dividing family (or individual) income by poverty guideline. We used multivariable-adjusted Cox proportional hazard models through a backward elimination method to evaluate associations between PIR, CVD, and all-cause mortality in cancer survivors. RESULTS: This cohort included 2,464 cancer survivors with a mean age of 62 (42% male) years. Compared with individuals with a higher PIR tertiles, those in the lowest PIR tertile had a higher rate of pre-existing CVD and post-acquired CVD. In participants with post-acquired CVD, the lowest PIR tertile had over two-fold increased risk mortality (Hazard Ratio (HR) = 2.17; 95% CI: 1.27-3.71) when compared to the highest PIR tertile. Additionally, we found that PIR was as strong a predictor of mortality in cancer survivors as CVD. In patients with no CVD, the lowest PIR tertile continued to have almost a two-fold increased risk of mortality (HR = 1.72; 95% CI: 1.69-4.35) when compared to a reference of the highest PIR tertile. CONCLUSIONS: In this large national study of cancer survivors, low PIR is associated with a higher prevalence of CVD. Low PIR is also associated with an increased risk of mortality in cancer survivors, showing a comparable impact to that of pre-existing and post-acquired CVD. Urgent public health resources are needed to further study and improve screening and access to care in this high-risk population.

Addressing social risks in cancer prevention and control presents a new opportunity for accelerating cancer health equity. As members of the American Society of Preventive Oncology (ASPO) Cancer Health Disparities Special Interest Group, we describe the current state of science on social risks in oncology research and practice. To reduce and eliminate the unjust burden of cancer, we also provide recommendations for multilevel research examining social risks as contributors to inequities and the development of social risks-focused interventions. Suggestions for research and practice are provided within levels of the socio-ecological model, including the interpersonal, organizational, community, and policy levels.

BACKGROUND: Hypertension is a risk factor for experiencing left ventricular ejection fraction (LVEF) declines during receipt of potentially cardiotoxic breast cancer (BC) treatment. We sought to determine whether the hypertension stage is associated with LVEF decline during BC treatment. METHODS: Across 24 centers, cardiac magnetic resonance measures of LVEF and brachial arterial blood pressure (BP) measurements were performed in women with stages I to III BC before and 3 months after initiating potentially cardiotoxic chemotherapy. Using multivariable analysis, we assessed in a blinded fashion the association between 3-month ΔLVEF and precancer treatment American Heart Association/American College of Cardiology stages of hypertension. RESULTS: Among 204 women, age averaged 56±1 years with 75% being White and 20% of Black race. Participants received anthracycline (45.6%), trastuzumab (22.5%), cyclophosphamide (52.9%), or paclitaxel (50%). After accounting for pretreatment LVEF, diabetes status, tobacco use, age, the number of antihypertensive medications, and body mass index, those with stage II hypertension experienced an LVEF decline of -2.89% ([95% CI, -0.69% to -5.19%]; P=0.01) relative to individuals with normal BP. Other stages saw nonsignificant declines relative to normal BP to elevated BP (-1.63% [95% CI, -0.62% to 3.88%]; P=0.16) and stage I hypertension (-0.94% [95% CI, -0.90% to 2.78%]; P=0.32). CONCLUSIONS: Compared with women receiving treatment for BC with normal BP, there is a stronger association of decline in LVEF in women with stage II hypertension relative to women with other hypertension stages. This raises the possibility that stage along with hypertension presence may be associated with an increased risk for the LVEF decline among women receiving potentially cardiotoxic chemotherapy for BC.

PURPOSE: Black women often experience poorer breast cancer-related outcomes and higher mortality than white women. A contributor to this disparity may relate to the disproportionate burden of cancer treatment-related cardiovascular (CV) toxicities. The objective of this review is to identify studies that report racial differences in CV toxicity risk. METHODS: Medline and Embase were searched for studies that assessed CV toxicities as the outcome(s) and included Black and White women with breast cancer. Studies were selected based on inclusion/exclusion criteria and through the use of multiple reviewers. RESULTS: The review included 13 studies following a review of 409 citations and 49 full-text articles. All studies were retrospective and 8/13 utilized data from the Surveillance, Epidemiology, and End Results-Medicare linked database. Trastuzumab was the most frequently studied treatment. The proportion of Black women in these studies ranged from 5.5 to 63%. A majority of studies reported a higher risk of CV toxicity amongst Black women when compared to white women (93%). Black women had up to a two times higher risk of CV toxicity (HR, 2.73 (CI, 1.24 to 6.01)) compared to white women. Only one study evaluated the role of socioeconomic factors in explaining racial differences in CV toxicity; however, the disparity remained even after adjusting for these factors. CONCLUSIONS: There is a critical need for more longitudinal studies that evaluate multilevel factors (e.g., psychosocial, biological) that may help to explain this disparity. IMPLICATIONS FOR CANCER SURVIVORS: Black cancer survivors may require additional surveillance and mitigation strategies to decrease disproportionate burden of CV toxicities.

BACKGROUND: We examined whether there are racial disparities in pain management, opioid medicine prescriptions, symptom severity, and quality of life constructs in breast cancer survivors. METHODS: We conducted a secondary analysis of longitudinal data from the Women's Hormonal Therapy Initiation and Persistence (WHIP) study (n = 595), a longitudinal study of hormonal receptor-positive breast cancer survivors. Upon study enrollment, patients completed a survey assessing an array of psychological, behavioral, and treatment outcomes, including adjuvant endocrine therapy (AET)-induced symptoms, and provided a saliva biospecimen. Opioid prescription records were extracted from the health maintenance organizations (HMOs) pharmacy database. The final analytic sample included women with complete HMO pharmacy records for 1 year. RESULTS: There were 251 eligible patients, of which 169 (67.3%) were White. The average age was 61.09 years old (SD = 11.07). One hundred seventy-two patients (68.5%) had received at least one opioid medication and 37.1% were prescribed opioids longer than 90 days (n = 93). Sixty-four Black patients (78%) had a record of being prescribed with opioids compared to 64% of White patients (n = 108, p = 0.03). Black patients reported worse vasomotor, neuropsychological, and gastrointestinal symptoms, as well as lower quality of life and greater healthcare discrimination than White patients (p's < 0.05). Black patients were more likely to be prescribed opioids for 90 days or longer compared to White patients, when controlling for age, marital status, income, body mass index (BMI), cancer stage, and chemotherapy status (adjusted Odds Ratio = 2.72, p = 0.014). CONCLUSION: Findings indicate that there are racial differences in opioid prescriptions supplied for pain management and symptomatic outcomes. Future research is needed to understand the causes of disparities in cancer pain management and symptomatic outcomes.

Cardiovascular disease is the leading cause of mortality among breast cancer (BC) patients aged 50 and above. Machine Learning (ML) models are increasingly utilized as prediction tools, and recent evidence suggests that incorporating social determinants of health (SDOH) data can enhance its performance. This study included females ≥ 18 years diagnosed with BC at any stage. The outcomes were the diagnosis and time-to-event of major adverse cardiovascular events (MACEs) within two years following a cancer diagnosis. Covariates encompassed demographics, risk factors, individual and neighborhood-level SDOH, tumor characteristics, and BC treatment. Race-specific and race-agnostic Extreme Gradient Boosting ML models with and without SDOH data were developed and compared based on their C-index. Among 4309 patients, 11.4% experienced a 2-year MACE. The race-agnostic models exhibited a C-index of 0.78 (95% CI 0.76-0.79) and 0.81 (95% CI 0.80-0.82) without and with SDOH data, respectively. In non-Hispanic Black women (NHB; n = 765), models without and with SDOH data achieved a C-index of 0.74 (95% CI 0.72-0.76) and 0.75 (95% CI 0.73-0.78), respectively. Among non-Hispanic White women (n = 3321), models without and with SDOH data yielded a C-index of 0.79 (95% CI 0.77-0.80) and 0.79 (95% CI 0.77-0.80), respectively. In summary, including SDOH data improves the predictive performance of ML models in forecasting 2-year MACE among BC females, particularly within NHB.
RESUMO
PURPOSE: Adjuvant endocrine therapy (AET) often causes debilitating endocrine symptoms that compromise quality of life (QOL) in women diagnosed with hormone receptor positive breast cancer (BC). We examined whether greater levels of physical activity (PA) or prolonged sitting were associated with reduced side effects or worse side effects of AET, respectively. METHODS: We used parallel process latent growth curve models to examine longitudinal patterns in PA and sitting behaviors, and their association with endocrine symptoms and QOL over 3 years of follow-up in 554 female BC survivors undergoing AET. RESULTS: At baseline, women were a mean age of 59 years, mostly white (72%), with overweight/obesity (67%), and approximately 50% were within 1 year of diagnosis. Unconditional models showed significant increases in PA (p < 0.01) over time but no change in sitting. Endocrine symptoms, general and BC-specific QOL all significantly worsened over time (p < 0.01). Parallel process models showed no cross-sectional or longitudinal associations between PA and endocrine symptoms. Higher levels of baseline PA were associated with higher baseline QOL scores (p = 0.01) but changes in PA were not associated with changes in QOL. Conversely, more sitting at baseline was associated with worse endocrine symptoms, general and BC specific QOL (ps <0.01). At baseline, having better QOL scores was associated with increases in sitting (ps <0.01), while having worse endocrine symptoms was associated with a slower rate of increase in sitting (p < 0.01). Increases in sitting time were also associated with a slower rate of increase in endocrine symptoms (p = 0.017). Model fit statistics (x2, CFI, TLI, SRMR) were acceptable. CONCLUSION: Both PA and sitting behaviors are important for the management of symptoms and in maintaining QOL in BC survivors. Women with already high symptom burden do not increase sitting time further but having better general and BC specific QOL to begin with means a greater decline over time.
