Reproductive risk factors for breast cancer and association with novel breast density measurements among Hispanic, Black, and White women

PURPOSE

There are differences in the distributions of breast cancer incidence and risk factors by race and ethnicity. Given the strong association between breast density and breast cancer, it is of interest describe racial and ethnic variation in the determinants of breast density.

METHODS

We characterized racial and ethnic variation in reproductive history and several measures of breast density for Hispanic (n = 286), non-Hispanic Black (n = 255), and non-Hispanic White (n = 1694) women imaged at a single hospital. We quantified associations between reproductive factors and percent volumetric density (PVD), dense volume (DV), non-dense volume (NDV), and a novel measure of pixel intensity variation (V) using multivariable-adjusted linear regression, and tested for statistical heterogeneity by race and ethnicity.

RESULTS

Reproductive factors most strongly associated with breast density were age at menarche, parity, and oral contraceptive use. Variation by race and ethnicity was most evident for the associations between reproductive factors and NDV (minimum p-heterogeneity:0.008) and V (minimum p-heterogeneity:0.004) and least evident for PVD (minimum p-heterogeneity:0.042) and DV (minimum p-heterogeneity:0.041).

CONCLUSION

Reproductive choices, particularly those related to childbearing and oral contraceptive use, may contribute to racial and ethnic variation in breast density.

An evaluation of readability and understandability of online education materials for breast cancer survivors

PURPOSE

We aimed to determine the availability of existing web-based educational materials on breast cancer survivorship and assess their readability and understandability.

METHODS

We identified materials eligible for review in two ways: (1) reviews of websites of major cancer-related organizations (e.g., American Cancer Society); (2) Google searches for breast cancer survivorship, breast cancer, breast cancer follow-up care, and cancer survivorship. We measured Flesch-Kincaid and New Dale Readability of existing breast cancer and breast cancer survivorship materials. Readability grade levels 5 to 8 were considered ideal to acceptable. We used the Patient Education Materials Assessment Tool (PEMAT) to measure the understandability of 53 videos and 152 written materials, such as booklets and manuals. A resource was considered understandable and/or actionable if it scored ≥ 70% on either the understandability section or the actionability section of the PEMAT.

RESULTS

We identified a total of 205 existing materials including brochures, booklets, facts sheets, websites, and videos in English. The average Flesch-Kincaid grade score of written educational materials was 9.7 (range 3.5-16.4), which translates to a 9th grade reading level. According to the New Dale-Chall readability assessment, most of the materials were in the 9 to 10 grade level range. The average PEMAT score was 88.6% (range 56-100%).

CONCLUSION

Patient educational materials are available online as printable, written materials, and videos and they focus on a wide selection of survivorship-related topics. Most of the breast cancer educational materials that are available online were above an 8th grade reading level. The PEMAT results, however, suggest that materials are easy to understand regarding word choice and style, use of numbers, organization, layout and design, and use of visual aids.

IMPLICATIONS FOR CANCER SURVIVORS

Understandable patient education materials are essential for guiding breast cancer survivors towards improving their health outcomes and optimizing their quality of life.

Reproductive factors related to childbearing and a novel automated mammographic measure, V

BACKGROUND

We investigated the associations between several reproductive factors related to childbearing and the variation (V) measure (a novel, objective, single summary measure of breast image intensity) by menopausal status.

METHODS

Our study included 3,814 cancer-free women within the Nurses' Health Study (NHS) and NHSII cohorts. The data on reproductive variables and covariates were obtained from biennial questionnaires closest to the mammogram date. V-measures were obtained from mammographic images using a previously developed algorithm capturing the standard deviation of pixel values. We used multivariate linear regression to examine the associations of parity, age at first birth, time between menarche and first birth, time since last pregnancy, and lifetime breastfeeding duration with V-measure, adjusting for breast cancer risk factors, including percent mammographic density (PMD). We further examined if these associations were statistically accounted for (mediated) by PMD.

RESULTS

Among premenopausal women, none of the reproductive factors were associated with V. Among postmenopausal women, inverse associations of parity and positive associations of age at first birth with V were mediated by PMD (percent mediated: nulliparity: 66.7%, p<0.0001; parity: 50.5%, p<0.01; age at first birth 76.1%, p<0.001) and were no longer significant in PMD-adjusted models. Lifetime duration of breastfeeding was positively associated with V (>36 vs. 0-<1 months β=0.29, 95% CI 0.07; 0.52, p-trend<0.01), independent of PMD.

CONCLUSIONS

Parity, age at first birth, and breastfeeding were associated with postmenopausal V.

IMPACT

This study highlights associations of reproductive factors with mammographic image intensity.

Women's Information Needs and Educational Preferences Regarding Lung Cancer Screening

Background: Physicians are less likely to discuss lung cancer screening (LCS) with women, and women have lower awareness of LCS availability. The objective of this qualitative study was to determine information needs, patient-provider communication barriers, and preferences for LCS education among women. Materials and Methods: Eight semistructured qualitative focus groups were conducted with 28 self-identified women meeting LCS eligibility criteria. Participants were recruited through a large health system, from a community-based LCS program, and through a national online database between October 2020 and March 2021. Focus groups were led by a trained moderator via Zoom. Audio recordings were transcribed and analyzed using thematic analysis by investigators. Results: LCS decision-making influences included: (1) Health care provider recommendation; (2) Self-advocacy; (3) Insurance coverage and cost; (4) Family; and (5) Interest in early detection. Participants preferred video and print materials, available at physician's office or shared by physician, without scare tactics or shaming about smoking, use clear language, with diverse participants and images. Preferred content focused on: (1) Benefits of early detection; (2) Lung cancer definition, statistics, and risk factors; (3) Benefits of quitting smoking; (4) Demonstration or explanation of how LCS is done; and (5) Availability of other tests and potential harms of screening. Conclusion: Women in our study had limited awareness of LCS and their eligibility and wanted recommendation and support for LCS from their health care providers. We identified addressable information needs about lung cancer and the screening process that can be used to improve LCS uptake in women and shared decision-making processes.

Addressing Social Risks to Accelerate Health Equity in Cancer Prevention and Control

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.

"Does Religious Service Attendance Modify the Relationship between Everyday Discrimination and Risk of Obesity? Results from the Study on Stress, Spirituality and Health"

This study examined the association of everyday discrimination with risk of obesity and the potential modifying effect of religious service attendance. Participants included Black, South Asian, and white women in three cohort studies that belong to the Study on Stress, Spirituality and Health. Logistic regression models estimated odds of obesity classification (BMI ≥ 30) relative to experiences of everyday discrimination. In initial pooled analyses, high levels of discrimination were related to increased odds of obesity. Race-specific analyses revealed marginal associations for white and South Asian women. Among Black women, high levels of discrimination and religious service attendance were both associated with higher odds of obesity. However, among women who attended religious services frequently, higher levels of everyday discrimination were associated with slightly lower odds of obesity. These findings underline the complex association between obesity and religion/spirituality, suggesting that higher levels of discrimination may uniquely activate religious resources or coping strategies. Findings highlight the need for additional studies to examine the impact of everyday discrimination on risk of obesity across racial/ethnic communities and how religious practices or coping strategies might affect these dynamics.

Impact of age, race, and family history on COVID-19-related changes in breast cancer screening among the Boston mammography cohort study

PURPOSE

We studied women enrolled in the Boston Mammography Cohort Study to investigate whether subgroups defined by age, race, or family history of breast cancer experienced differences in the incidence of screening or diagnostic imaging rates during the COVID-19 lockdown and had slower rebound in the incidence of these rates during reopening.

METHODS

We compared the incidence of monthly breast cancer screening and diagnostic imaging rates over during the pre-COVID-19 (January 2019-February 2020), lockdown (March-May 2020), and reopening periods (June-December 2020), and tested for differences in the monthly incidence within the same period by age (< 50 vs ≥ 50), race (White vs non-White), and first-degree family history of breast cancer (yes vs no).

RESULTS

Overall, we observed a decline in breast cancer screening and diagnostic imaging rates over the three time periods (pre-COVID-19, lockdown, and reopening). The monthly incidence of breast cancer screening rates for women age ≥ 50 was 5% higher (p = 0.005) in the pre-COVID-19 period (January 2019-February 2020) but was 19% lower in the reopening phase (June-December 2020) than that of women aged < 50 (p < 0.001). White participants had 36% higher monthly incidence of breast cancer diagnostic imaging rates than non-White participants (p = 0.018).

CONCLUSION

The rebound in screening was lower in women age ≥ 50 and lower in non-White women for diagnostic imaging. Careful attention must be paid as the COVID-19 recovery continues to ensure equitable resumption of care.

Age, Body Mass Index, Tumor Subtype, and Racial and Ethnic Disparities in Breast Cancer Survival

Importance

Black women in the United States have higher breast cancer (BC) mortality rates than White women. The combined role of multiple factors, including body mass index (BMI), age, and tumor subtype, remains unclear.

Objective

To assess the association of race and ethnicity with survival among clinical trial participants with early-stage BC (eBC) according to tumor subtype, age, and BMI.

Design, Setting, and Participants

This cohort study analyzed survival data, as of November 12, 2021, from participants enrolled between 1997 and 2010 in 4 randomized adjuvant chemotherapy trials: Cancer and Leukemia Group B (CALGB) 9741, 49907, and 40101 as well as North Central Cancer Treatment Group (NCCTG) N9831, legacy groups of the Alliance of Clinical Trials in Oncology. Median follow-up was 9.8 years.

Exposures

Non-Hispanic Black and Hispanic participants were compared with non-Hispanic White participants within subgroups of subtype (hormone receptor positive [HR+]/ERBB2 [formerly HER2] negative [ERBB2-], ERBB2+, and HR-/ERBB2-), age (<50, 50 to <65, and ≥65 years), and BMI (<18.5, 18.5 to <25.0, 25.0 to <30.0, and ≥30.0).

Main Outcomes and Measures

Recurrence-free survival (RFS) and overall survival (OS).

Results

Of 9479 participants, 436 (4.4%) were Hispanic, 871 (8.8%) non-Hispanic Black, and 7889 (79.5%) non-Hispanic White. The median (range) age was 52 (19.0-89.7) years. Among participants with HR+/ERBB2- tumors, non-Hispanic Black individuals had worse RFS (hazard ratio [HR], 1.49; 95% CI, 1.04-2.12; 5-year RFS, 88.5% vs 93.2%) than non-Hispanic White individuals, although the global test for association of race and ethnicity with RFS was not significant within any tumor subtype. There were no OS differences by race and ethnicity in any subtype. Race and ethnicity were associated with OS in young participants (age <50 years; global P = .008); young non-Hispanic Black participants (HR, 1.34; 95% CI, 1.04-1.71; 5-year OS, 86.6% vs 92.0%) and Hispanic participants (HR, 1.62; 95% CI, 1.16-2.29; 5-year OS, 86.2% vs 92.0%) had worse OS than young non-Hispanic White participants. Race and ethnicity were associated with RFS in participants with BMIs of 25 to less than 30, with non-Hispanic Black participants having worse RFS (HR, 1.81; 95% CI, 1.23-2.68; 5-year RFS, 83.2% vs 87.3%) than non-Hispanic White participants.

Conclusions and Relevance

In this cohort study, racial and ethnic survival disparities were identified in patients with eBC receiving standardized initial care, and potentially at-risk subgroups, for whom focused interventions may improve outcomes, were found.

Breast cancer survivorship experiences among Black women

BACKGROUND

Black women experience significant disparities in breast cancer across the care continuum, including survivorship. Ensuring that Black women obtain high-quality follow-up care is critical but understudied. This study was aimed at understanding the experiences and needs of Black women during breast cancer survivorship.

METHODS

Black patients diagnosed with invasive breast cancer within the past 5 years were invited to participate in a focus group and complete a survey. Focus groups examined the following: (1) the transition from active treatment to survivorship; (2) interactions with health care providers; (3) survivorship experiences, information needs, and preferences; and (4) existing educational materials. Results were thematically coded and analyzed for main themes. Surveys collected information on sociodemographics, health care experiences, quality of life, lifestyle, and education needs.

RESULTS

The study enrolled 53 participants, 43 of whom completed a survey and participated in one of 11 focus groups. The median age was 54 years, 44% had private insurance, 81% were English speaking, and 86% had completed their treatment more than a year before. Participants identified the importance of relationships with health care providers, gaps in survivorship care, experiences with cancer-related symptoms, challenges with mental health, worry about recurrence, body image, cancer financial toxicity, and coping through religion and spirituality. Unmet needs were centered around preparation for long-term symptoms, diet and physical activity, emotional support, and more explanations of information resources. Participants reported preferences for educational videos, personal stories, and culturally relevant content.

CONCLUSIONS

Some Black breast cancer survivors may have specific challenges and preferences. Supportive interventions that address these concerns can be responsive and help to ameliorate disparities.

Inequities in referrals to a breast cancer risk assessment and prevention clinic: a mixed methods study

BACKGROUND

Inequitable access to personalized breast cancer screening and prevention may compound racial and ethnic disparities in outcomes. The Breast Cancer Personalized Risk Assessment, Education and Prevention (B-PREP) program, located within the Brigham and Women's Hospital (BWH) Comprehensive Breast Health Center (BHC), provides care to patients at high risk for developing breast cancer. We sought to characterize the differences between BWH primary care patients referred specifically to B-PREP for risk evaluation and those referred to the BHC for benign breast conditions. Through interviews with primary care clinicians, we sought to explore contributors to potentially inequitable B-PREP referral patterns.

METHODS

We used electronic health record data and the B-PREP clinical database to identify patients referred by primary care clinicians to the BHC or B-PREP between 2017 and 2020. We examined associations with likelihood of referral to B-PREP for risk assessment. Semi-structured interviews were conducted with nine primary care clinicians from six clinics to explore referral patterns.

RESULTS

Of 1789 patients, 78.0% were referred for benign breast conditions, and 21.5% for risk assessment. In multivariable analyses, Black individuals were less likely to be referred for risk than for benign conditions (OR 0.38, 95% CI:0.23-0.63) as were those with Medicaid/Medicare (OR 0.72, 95% CI:0.53-0.98; OR 0.52, 95% CI:0.27-0.99) and those whose preferred language was not English (OR 0.26, 95% CI:0.12-0.57). Interviewed clinicians described inconsistent approaches to risk assessment and variable B-PREP awareness.

CONCLUSIONS

In this single-site evaluation, among individuals referred by primary care clinicians for specialized breast care, Black, publicly-insured patients, and those whose preferred language was not English were less likely to be referred for risk assessment. Larger studies are needed to confirm these findings. Interventions to standardize breast cancer risk assessment in primary care may improve equity.

Amygdalar activity measured using FDG-PET/CT at head and neck cancer staging independently predicts survival

IMPORTANCE

The mechanisms underlying the association between chronic stress and higher mortality among individuals with cancer remain incompletely understood.

OBJECTIVE

To test the hypotheses that among individuals with active head and neck cancer, that higher stress-associated neural activity (ie. metabolic amygdalar activity [AmygA]) at cancer staging associates with survival.

DESIGN

Retrospective cohort study.

SETTING

Academic Medical Center (Massachusetts General Hospital, Boston).

PARTICIPANTS

240 patients with head and neck cancer (HNCA) who underwent 18F-FDG-PET/CT imaging as part of initial cancer staging.

MEASUREMENTS

18F-FDG uptake in the amygdala was determined by placing circular regions of interest in the right and left amygdalae and measuring the mean tracer accumulation (i.e., standardized uptake value [SUV]) in each region of interest. Amygdalar uptake was corrected for background cerebral activity (mean temporal lobe SUV).

RESULTS

Among individuals with HNCA (age 59±13 years; 30% female), 67 died over a median follow-up period of 3 years (IQR: 1.7-5.1). AmygA associated with heightened bone marrow activity, leukocytosis, and C-reactive protein (P<0.05 each). In adjusted and unadjusted analyses, AmygA associated with subsequent mortality (HR [95% CI]: 1.35, [1.07-1.70], P = 0.009); the association persisted in stratified subset analyses restricted to patients with advanced cancer stage (P<0.001). Individuals within the highest tertile of AmygA experienced a 2-fold higher mortality rate compared to others (P = 0.01). The median progression-free survival was 25 months in patients with higher AmygA (upper tertile) as compared with 36.5 months in other individuals (HR for progression or death [95%CI], 1.83 [1.24-2.68], P = 0.001).

CONCLUSIONS AND RELEVANCE

AmygA, quantified on routine 18F-FDG-PET/CT images obtained at cancer staging, independently and robustly predicts mortality and cancer progression among patients with HNCA. Future studies should test whether strategies that attenuate AmygA (or its downstream biological consequences) may improve cancer survival.

Advancing health equity through implementation science: Identifying and examining measures of the outer setting

BACKGROUND

Implementation science (IS) could accelerate progress toward achieving health equity goals. However, the lack of attention to the outer setting where interventions are implemented limits applicability and generalizability of findings to different populations, settings, and time periods. We developed a data resource to assess outer setting across seven centers funded by the National Cancer Institute's IS Centers in Cancer Control (ISC3) Network Program.

OBJECTIVE

To describe the development of the Outer Setting Data Resource and characterize the county-level outer context across Centers.

METHODS

Our Data Resource captures seven key environments, including: (1) food; (2) physical; (3) economic; (4) social; (5) health care; (6) cancer behavioral and screening; and (7) cancer-related policy. Data were obtained from public sources including the US Census and American Community Survey. We present medians and interquartile ranges based on the distribution of all counties in the US, all ISC3 centers, and within each Center for twelve selected measures. Distributions of each factor are compared with the national estimate using single sample sign tests.

RESULTS

ISC3 centers' catchment areas include 458 counties and over 126 million people across 28 states. The median percentage of population living within ½ mile of a park is higher in ISC3 counties (38.0%, interquartile range (IQR): 16.0%-59.0%) compared to nationally (18.0%, IQR: 7.0%-38.0%; p < 0.0001). The median percentage of households with no broadband access is significantly lower in ISC3 counties (28.4%, IQR: 21.4%-35.6%) compared the nation overall (32.8%, IQR: 25.8%-41.2%; p < 0.0001). The median unemployment rate was significantly higher in ISC3 counties (5.2%, IQR: 4.1%-6.4%) compared to nationally (4.9%, 3.6%-6.3%, p = 0.0006).

CONCLUSIONS

Our results indicate that the outer setting varies across Centers and often differs from the national level. These findings demonstrate the importance of assessing the contextual environment in which interventions are implemented and suggest potential implications for intervention generalizability and scalability.

Religion/Spirituality and Prevalent Hypertension among Ethnic Cohorts in the Study on Stress, Spirituality, and Health

BACKGROUND

Hypertension is a significant public health issue, particularly for Blacks, Hispanics/Latinos, and South Asians who are at greater risk than whites. Religion and spirituality (R/S) have been shown to be protective, but this has been identified primarily in whites with limited R/S measures examined (i.e., religious service attendance).

PURPOSE

To assess hypertension prevalence (HP) in four racial/ethnic groups while incorporating an array of R/S variables, including individual prayer, group prayer, nontheistic daily spiritual experiences, yoga, gratitude, positive religious coping, and negative religious coping.

METHODS

Data were drawn from the Study on Stress, Spirituality, and Health, a consortium of ethnically diverse U.S. cohorts. The sample included 994 Black women, 838 Hispanic/Latino men and women, 879 South Asian men and women, and 3681 white women. Using a cross-sectional design, prevalence ratios for R/S and hypertension were reported for each cohort, in addition to pooled analyses. Given differences in R/S among men and women, all models were stratified by gender.

RESULTS

Different patterns of associations were found between women and men. Among women: 1) religious attendance was associated with lower HP among Black and white women; 2) gratitude was linked to lower HP among Hispanic/Latino, South Asian, and white women; 3) individual prayer was associated with higher HP among Hispanic/Latino and white women; 4) yoga was associated with higher HP among South Asian women, and 5) negative religious coping was linked to higher HP among Black women. Among men: significant results were only found among Hispanic/Latino men. Religious attendance and individual prayer were associated with higher HP, while group prayer and negative religious coping were associated with lower HP.

CONCLUSION

Religion/spirituality is a multifaceted construct that manifests differently by race/ethnicity and gender. Medical practitioners should avoid a one-size-fits-all approach to this topic when evaluating prevalent hypertension in diverse communities.

Bone-Modifying Agents in Early Breast Cancer: Making Sense of Conflicting Data

The use of adjuvant bone-modifying agents to reduce risk of recurrence in patients with early-stage breast cancer has not been widely embraced because of conflicting data and small absolute benefits. The clinical practice guideline produced jointly by the American Society of Clinical Oncology and Cancer Care Ontario recommends discussion of risks/benefits with postmenopausal patients with early-stage breast cancer about adjuvant bisphosphonates and does not recommend use of adjuvant denosumab to prevent breast cancer recurrence.1.

Cardiovascular Disease in Adult Cancer Survivors: a Review of Current Evidence, Strategies for Prevention and Management, and Future Directions for Cardio-oncology

PURPOSE OF REVIEW

Cardiovascular disease is long-term complication of both cancer and anti-cancer treatment and can have significant ramifications for health-related quality of life and mortality. This narrative review explores the current evidence linking cardiovascular disease and cancer, as well as exploring strategies for the prevention and management of cardiovascular disease, and outlines future opportunities in the field of cardio-oncology.

RECENT FINDINGS

Cancer confers risk for various cardiovascular diseases including heart failure, cardiomyopathy, arrhythmia, coronary heart disease, stroke, venous thromboembolism, and valvular heart disease. Cancer treatment, in particular agents such as platinum-based chemotherapy, anthracyclines, hormonal treatments, and thoracic radiotherapy, further increases risk. While cardiovascular disease can be identified early and effectively managed in cancer survivors, cardiovascular screening and management does not typically feature in routine long-term cancer care of adult cancer survivors. Cancer and cancer treatment can accelerate the development of cardiovascular disease. Further research into screening and management strategies for cardiovascular disease, along with evidence-based guidelines, is required to ensure adult cancer survivors receive appropriate long-term care.

Underrepresented minority clinical trial participation: Perspectives of the research care team and patients

93

Background: Clinical trials (CT) are important treatment options for patients with cancer, yet enrollment rates among underrepresented minority (URM) patients remain suboptimal. Oncology care teams need to assess barriers and facilitators of CT participation and identify practices and resources to better support patients. As part of a larger mixed-methods project, we elicited perspectives on improving URM CT enrollment from oncology research care teams and patients. Methods: We conducted four 60-minute focus groups with 12 oncology physicians, 12 research nurses, and nine clinical research coordinators, and semi-structured interviews with nine URM CT patients at a large academic medical center between January and December 2021. Results: Thematic analysis of the focus groups and interviews identified multiple barriers and potential resources and supports at the patient, healthcare team, institutional, and trial design levels. Barriers included difficulty ensuring patient understanding and informed consent, especially among patients with low health literacy and limited-English proficiency, complex logistical and financial demands of CT participation for patients, and the lack of multidisciplinary oncology care team collaboration. Collectively, these barriers undermined communication, trust, and the quality of patients’ relationships with the care team, all affecting CT participation. Suggested resources and practices included proactive needs assessments for all patients with early engagement of social workers, providing a liaison or navigator for each patient, services and support to reduce patient out of pocket costs, expansion of non-English materials availability and increased used of interpreters, increased training and diversity for all care team roles, and simplifying CT requirements by streamlining informed consent documents, eliminating unnecessary CT-related appointments, and broadening eligibility criteria. Conclusions: Findings suggest that changes in clinical trial design, care team coordination, and early assessment and monitoring of patients’ needs and experiences may help reduce access barriers and increase enrollment of URM patients into cancer CTs.

The Association of Religion and Spirituality with Obesity and Weight Change in the USA: A Large-Scale Cohort Study

The association between religion, spirituality, and body weight is controversial, given the methodological limitations of existing studies. Using the Nurses' Health Study II cohort, follow-up occurred from 2001 to 2015, with up to 35,547 participants assessed for the religious or spiritual coping and religious service attendance analyses. Cox regression and generalized estimating equations evaluated associations with obesity and weight change, respectively. Religious or spiritual coping and religious service attendance had little evidence of an association with obesity. Compared with not using religious or spiritual coping at all, the fully adjusted hazard ratios (HRs) were minimally different across categories: a little bit (HR = 1.05, 95% CI: 0.92-1.18), a medium amount (HR = 1.09, 95% CI: 0.96-1.24), and a lot (HR = 1.10; 95% CI: 0.96-1.25) (P_trend = 0.17). Compared with participants who never or almost never attend religious meetings or services, there was little evidence of an association between those attending less than once/month (HR = 1.08, 95% CI: 0.97-1.10), 1-3 times/month (HR = 1.01, 95% CI: 0.90-1.13), once/week (HR = 0.92, 95% CI: 0.83-1.02), and more than once/week (HR = 0.94, 95% CI: 0.82-1.07) (P_trend = 0.06). Findings were similar for weight change. There was no significant association between religious or spiritual coping, religious service attendance, obesity, and weight change. While religion and spirituality are prominent in American society, they are not important psychosocial factors influencing body weight in this sample.

Patient-Reported Experiences of Breast Cancer Screening, Diagnosis, and Treatment Delay, and Telemedicine Adoption during COVID-19

Purpose: To evaluate and quantify potential sociodemographic disparities in breast cancer screening, diagnosis, and treatment due to the COVID-19 pandemic, and the use of telemedicine. Methods: We fielded a 52-item web-based questionnaire from 14 May 2020 to 1 July 2020 in partnership with several U.S.-based breast cancer advocacy groups. Individuals aged 18 or older were eligible for this study if they: (1) received routine breast cancer screening; OR (2) were undergoing diagnostic evaluation for breast cancer; OR (3) had ever been diagnosed with breast cancer. We used descriptive statistics to understand the extent of cancer care delay and telemedicine adoption and used multivariable logistic regression models to estimate the association of sociodemographic factors with odds of COVID-19-related delays in care and telemedicine use. Results: Of 554 eligible survey participants, 493 provided complete data on demographic and socioeconomic factors and were included in the analysis. Approximately half (n = 248, 50.3%) had a personal history of breast cancer. Overall, 188 (38.1%) participants had experienced any COVID-19-related delay in care including screening, diagnosis, or treatment, and 339 (68.8) reported having at least one virtual appointment during the study period. Compared to other insurance types, participants with Medicaid insurance were 2.58 times more likely to report a COVID-19-related delay in care (OR 2.58, 95% Cl: 1.05, 6.32; p = 0.039). Compared to participants with a household income of less than USD 50,000, those with a household income of USD 150,000 or more were 2.38 (OR 2.38, 95% Cl: 1.09, 5.17; p = 0.029) times more likely to adopt virtual appointments. Self-insured participants were 70% less likely to use virtual appointment compared to those in other insurance categories (OR 0.28, 95% Cl: 0.11, 0.73; p = 0.009). Conclusions: The COVID-19 pandemic has had a significant impact on breast cancer screening, diagnosis, and treatment, and accelerated the delivery of virtual care. Lower-income groups and patients with certain insurance categories such as Medicaid or self-insured could be more likely to experience care delay or less likely to use telemedicine. Careful attention must be paid to vulnerable groups to insure equity in breast cancer-related service utilization and telemedicine access during and beyond the COVID-19 pandemic.

The mental health burden of racial and ethnic minorities during the COVID-19 pandemic

Racial/ethnic minorities have been disproportionately impacted by COVID-19. The effects of COVID-19 on the long-term mental health of minorities remains unclear. To evaluate differences in odds of screening positive for depression and anxiety among various racial and ethnic groups during the latter phase of the COVID-19 pandemic, we performed a cross-sectional analysis of 691,473 participants nested within the prospective smartphone-based COVID Symptom Study in the United States (U.S.) and United Kingdom (U.K). from February 23, 2021 to June 9, 2021. In the U.S. (n=57,187), compared to White participants, the multivariable odds ratios (ORs) for screening positive for depression were 1·16 (95% CI: 1·02 to 1·31) for Black, 1·23 (1·11 to 1·36) for Hispanic, and 1·15 (1·02 to 1·30) for Asian participants, and 1·34 (1·13 to 1·59) for participants reporting more than one race/other even after accounting for personal factors such as prior history of a mental health disorder, COVID-19 infection status, and surrounding lockdown stringency. Rates of screening positive for anxiety were comparable. In the U.K. (n=643,286), racial/ethnic minorities had similarly elevated rates of positive screening for depression and anxiety. These disparities were not fully explained by changes in leisure time activities. Racial/ethnic minorities bore a disproportionate mental health burden during the COVID-19 pandemic. These differences will need to be considered as health care systems transition from prioritizing infection control to mitigating long-term consequences.

Trends in breast and prostate cancer screening and diagnostic procedures during the COVID-19 pandemic in central Massachusetts

PURPOSE

We calculated rates of breast and prostate cancer screening and diagnostic procedures performed during the COVID-19 pandemic through December 2021 compared to the same months in 2019 in a large healthcare provider group in central Massachusetts.

METHODS

We included active patients of the provider group between January 2019 and December 2021 aged 30-85 years. Monthly rates of screening mammography and digital breast tomosynthesis, breast MRI, total prostate specific antigen (PSA), and breast or prostate biopsy per 1,000 people were compared by year overall, by age, and race/ethnicity. Completed procedures were identified by relevant codes in electronic health record data.

RESULTS

Rates of screening mammography, tomosynthesis, and PSA testing reached the lowest levels in April-May 2020. Breast cancer screening rates decreased 43% in March and 99% in April and May 2020, compared to 2019. Breast cancer screening rates increased gradually beginning in June 2020 through 2021, although more slowly in Black and Hispanic women and in women aged 75-85. PSA testing rates decreased 34% in March, 78% in April, and 53% in May 2020, but rebounded to pre-pandemic levels by June 2020; trends were similar across groups defined by age and race/ethnicity.

CONCLUSION

The observed decline in two common screening procedures during the COVID-19 pandemic reflects the impact of the pandemic on cancer early detection and signals potential downstream effects on the prognosis of delayed cancer diagnoses. The slower rate of return for breast cancer screening procedures in certain subgroups should be investigated to ensure all women return for routine screenings.

Racial and Sex Disparities in Gout Prevalence Among US Adults

IMPORTANCE

Emerging data suggest gout and hyperuricemia may now be more frequent among Black adults in the US than White adults, especially Black women. However, national-level, sex-specific general population data on racial differences in gout prevalence and potential socioclinical risk factors are lacking.

OBJECTIVE

To identify sex-specific factors driving disparities between Black and White adults in contemporary gout prevalence in the US general population.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional analysis used nationally representative, decadal survey data from successive cycles of the National Health and Nutrition Examination Survey from 2007 to 2016. Data were analyzed from November 1, 2019, through May 31, 2021. Participants included US adults self-reporting Black or White race.

EXPOSURES

Self-reported race, excess body mass index, chronic kidney disease (CKD; defined as estimated glomerular filtration rate <60 mL/min/1.73 m2, according to latest equations without race coefficient), poverty, poor-quality diet, low educational level, alcohol consumption, and diuretic use.

MAIN OUTCOMES AND MEASURES

Race- and sex-specific prevalence of physician- or clinician-diagnosed gout and hyperuricemia and their differences before and after adjusting for potential socioclinical risk factors.

RESULTS

A total of 18 693 participants were included in the analysis, consisting of 3304 Black women (mean [SD] age, 44.8 [0.4] years), 6195 White women (mean [SD] age, 49.8 [0.3] years), 3085 Black men (mean [SD] age, 43.6 [0.5] years]), and 6109 White men (mean [SD] age, 48.2 [0.3] years). Age-standardized prevalence of gout was 3.5% (95% CI, 2.7%-4.3%) in Black women and 2.0% (95% CI, 1.5%-2.5%) in White women (age-adjusted odds ratio [OR], 1.81 [95% CI, 1.29-2.53]); prevalence was 7.0% (95% CI, 6.2%-7.9%) in Black men and 5.4% (95% CI, 4.7%-6.2%) in White men (age-adjusted OR, 1.26 [95% CI, 1.02-1.55]). These associations attenuated after adjusting for poverty, diet, body mass index, and CKD among women and for diet and CKD among men but became null after adjusting for all risk factors (ORs, 1.05 [95% CI, 0.67-1.65] among women and 1.05 [95% CI, 0.80-1.35] among men). Hyperuricemia end point findings were similar.

CONCLUSIONS AND RELEVANCE

In this nationally representative race- and sex-specific cross-sectional study of US adults, gout was more prevalent in adults self-reporting Black race during a recent 10-year period compared with their White counterparts. These racial differences may be explained by sex-specific differences in diet and social determinants of health and clinical factors. Culturally informed efforts focusing on these factors could reduce current gout-related disparities.

Abstract 494: Role of age, BMI, and tumor subtype in racial/ethnic disparities in breast cancer survival: A pooled analysis of four Alliance adjuvant clinical trials

Background: Previous studies have demonstrated poorer survival of Black women with breast cancer. We assessed whether race/ethnicity was associated with disease-free (DFS) and overall survival (OS) among women with breast cancer enrolled in clinical trials for early-stage breast cancer according to tumor subtype, age, and body mass index (BMI).

Methods: 10,011 women enrolled in one of four adjuvant chemotherapy trials: CALGB 9741, CALGB 49907, CALGB 40101, or NCCTG N9831. 9918 participants had available DFS and/or OS data and were included in the analysis. Cox models were used to estimate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between race/ethnicity and DFS and OS. We compared Non-Hispanic (NH) Black (n=871), Hispanic (n=436), and other race participants (n=283) to NH Whites (n=7889). We assessed associations within strata of age group (&lt;50, 50-&lt;65, or ≥65), tumor subtype (hormone receptor (HR)+/HER2-, HR-/HER2+, or HR-/HER2-), and BMI (&lt;25, 25-&lt;30, or ≥30).

Results: In multivariable-adjusted models, NH Black patients under 50 years of age had worse DFS compared to NH White patients (HR: 1.34, 95% CI: 1.10-1.62) and worse OS (HR: 1.64, 95% CI: 1.30-2.07). The differences in DFS and OS persisted in patients ages 50 to &lt;65, though there were no significant differences in DFS or OS between NH Black and NH White patients ages ≥65. Among Hispanic and NH White participants, younger age at diagnosis was associated with greater DFS compared with older age overall while this was not true for NH Black patients. Among patients with HR+/HER2- tumors, NH Black patients when compared to NH White patients had worse DFS (HR 1.33, 95% CI: 1.04-1.70) but there was not a significant difference in OS (HR 1.35, 95% CI: 1.00-1.83). DFS and OS for other tumor subtypes did not significantly differ by race. Among patients with BMI &lt;25, NH Black patients had significantly worse DFS (HR: 1.70, 95% CI: 1.25-2.30) and OS (HR:1.76, 95% CI:1.20-2.58) compared to NH White patients. There was no difference in survival between different race/ethnicity groups among individuals with BMI ≥25.

Conclusions: Our results identified subgroups that may contribute to the observed disparities in survival between NH Black and NH White women with early-stage breast cancer. The greatest disparities are among individuals &lt;50 years of age, those with HR+/HER2-, and those with BMI &lt;25. These differences exist even within clinical trial populations with similar initial therapy, suggesting that disparities may be influenced by inequities in survivorship care and long-term treatment, such as endocrine therapy adherence and persistence, and/or differences in tumor or host biology.

Cancer diagnosis, cancer treatment, and association with cardiovascular disease in older adults: Results from ASPREE

12086

Background: New treatments and early detection measures have led to declines in cancer mortality rates and a growing population of cancer survivors at risk of short- and long-term effects of cancer and cancer treatment (C&CT), including cardiovascular disease (CVD). Although shared risk factors may contribute, several C&CT-related mechanisms including inflammation, treatment-related cardiotoxicity, and coagulation disorders may play a role. There are several studies exploring the link between C&CT and CVD; however, many do not examine risk stratified by cancer type or disease extent, nor investigate the impact of different treatment modalities. Methods: This analysis utilized data from the ASPirin in Reducing Events in the Elderly (ASPREE) trial, an international, multi-center, double-blinded randomized controlled trial that investigated the benefits and risks of aspirin in healthy older people. Multivariate time-dependent Cox regression models (adjusted for clinically significant factors including age, gender, smoking, and metabolic disease) were used to investigate the impact of C&CT on myocardial infarction, stroke, hospitalization for heart failure, and a composite endpoint combining these. Crude incidence rates were estimated using a competing risks regression model. Subgroup analysis was performed by metastatic status, cancer type, and treatment modality. Results: Of the 19,114 ASPREE participants (56% female; median age 75.1 years; median follow up 4.7 years), 1,933 received a post-randomisation cancer diagnosis. Participants with cancer had a greater rate and risk of CVD than those without cancer (15.3 per 1000 person-years (/1000pyrs] vs 10.5/1000pyrs, respectively; Hazard Ratio [HR] = 1.70, 95% Confidence Interval [CI] 1.32-2.10). The greatest increase in risk was seen for hospitalization for heart failure (HR 2.00, 1.18-3.38, 95% CI 1.18-3.38), although increases in risk were also seen for myocardial infarction, all-stroke, and ischaemic stroke. In subgroup analysis by cancer type, blood cancer (HR 2.33, 95% CI 1.25-4.36), lung cancer (HR 2.76, 95% CI 1.23-6.19), and melanoma (HR 1.97, 95% CI 1.02-3.82) were associated with an increased risk of composite CVD. ‘Any cancer treatment’ conferred increased risk of hospitalisation for heart failure (HR 1.78, 95% CI 1.15-2.75), although individual treatment modalities, including cytotoxic chemotherapy, targeted therapy, and radiotherapy conferred increased risks of various cardiovascular outcomes. Conclusions: Our findings indicate that both cancer and anti-cancer treatment confer risk for CVD in the elderly, the magnitude of which varied depending on cancer type and treatment modality. Given the implications of cardiovascular events for quality of life and mortality, these results support the integration of CVD screening and management into routine care for cancer survivors.

Depression, religiosity, and telomere length in the Study on Stress, Spirituality, and Health (SSSH)

Prospective studies on the association between depression and telomere length have produced mixed results and have been largely limited to European ancestry populations. We examined the associations between depression and telomere length, and the modifying influence of religion and spirituality, in four cohorts, each representing a different race/ethnic population. Relative leukocyte telomere length (RTL) was measured by a quantitative polymerase chain reaction. Our result showed that depression was not associated with RTL (percent difference: 3.0 95% CI: -3.9, 10.5; p = 0.41; p-heterogeneity across studies = 0.67) overall or in cohort-specific analyses. However, in cohort-specific analyses, there was some evidence of effect modification by the extent of religiosity or spirituality, religious congregation membership, and group prayer. Further research is needed to investigate prospective associations between depression and telomere length, and the resources of resilience including dimensions of religion and spirituality that may impact such dynamics in diverse racial/ethnic populations.

Religious or spiritual coping, religious service attendance, and type 2 diabetes: A prospective study of women in the United States

PURPOSE

To investigate religion and spirituality (R/S) as psychosocial factors in type 2 diabetes risk.

METHODS

Using the Nurses' Health Study II, we conducted a 14-year prospective analysis of 46,713 women with self-reported use of religion or spiritual beliefs to cope with stressful situations, and 42,825 women with self-reported religious service attendance, with respect to type 2 diabetes. Cox regression was used to assess the associations.

RESULTS

Compared with not using religious or spiritual coping at all, the fully-adjusted hazard ratios (HR) were minimally different across all categories: a little bit (HR=1.01; 95% CI:0.85, 1.19), a medium amount (HR=0.96; 95% CI:0.80, 1.14), a lot (HR=0.93; 95% CI: 0.77, 1.11) (P_trend=0.24). Similarly, compared with participants who never or almost never attend religious meetings or services, there were minimal differences with participants attending less than once/month (HR=1.06; 95% CI:0.92, 1.22), 1-3 times/month (HR=1.00; 95% CI:0.85, 1.17), once/week (HR=0.98; 95% CI:0.85, 1.14), more than once/week (HR=1.20; 95% CI:1.01, 1.43) (P_trend=0.29). Perceived stress did not modify these associations. Our hypothesis of mediated effects through lifestyle factors and social integration was not supported.

CONCLUSIONS

R/S was not significantly associated with type 2 diabetes, but its role in other chronic conditions may be important.

Self-reported COVID-19 vaccine hesitancy and uptake among participants from different racial and ethnic groups in the United States and United Kingdom

Worldwide, racial and ethnic minorities have been disproportionately impacted by COVID-19 with increased risk of infection, its related complications, and death. In the initial phase of population-based vaccination in the United States (U.S.) and United Kingdom (U.K.), vaccine hesitancy may result in differences in uptake. We performed a cohort study among U.S. and U.K. participants who volunteered to take part in the smartphone-based COVID Symptom Study (March 2020-February 2021) and used logistic regression to estimate odds ratios of vaccine hesitancy and uptake. In the U.S. (n = 87,388), compared to white participants, vaccine hesitancy was greater for Black and Hispanic participants and those reporting more than one or other race. In the U.K. (n = 1,254,294), racial and ethnic minority participants showed similar levels of vaccine hesitancy to the U.S. However, associations between participant race and ethnicity and levels of vaccine uptake were observed to be different in the U.S. and the U.K. studies. Among U.S. participants, vaccine uptake was significantly lower among Black participants, which persisted among participants that self-reported being vaccine-willing. In contrast, statistically significant racial and ethnic disparities in vaccine uptake were not observed in the U.K sample. In this study of self-reported vaccine hesitancy and uptake, lower levels of vaccine uptake in Black participants in the U.S. during the initial vaccine rollout may be attributable to both hesitancy and disparities in access.

A genome-wide association study of mammographic texture variation

Background

Breast parenchymal texture features, including grayscale variation (V), capture the patterns of texture variation on a mammogram and are associated with breast cancer risk, independent of mammographic density (MD). However, our knowledge on the genetic basis of these texture features is limited.

Methods

We conducted a genome-wide association study of V in 7040 European-ancestry women. V assessments were generated from digitized film mammograms. We used linear regression to test the single-nucleotide polymorphism (SNP)-phenotype associations adjusting for age, body mass index (BMI), MD phenotypes, and the top four genetic principal components. We further calculated genetic correlations and performed SNP-set tests of V with MD, breast cancer risk, and other breast cancer risk factors.

Results

We identified three genome-wide significant loci associated with V: rs138141444 (6q24.1) in ECT2L, rs79670367 (8q24.22) in LINC01591, and rs113174754 (12q22) near PGAM1P5. 6q24.1 and 8q24.22 have not previously been associated with MD phenotypes or breast cancer risk, while 12q22 is a known locus for both MD and breast cancer risk. Among known MD and breast cancer risk SNPs, we identified four variants that were associated with V at the Bonferroni-corrected thresholds accounting for the number of SNPs tested: rs335189 (5q23.2) in PRDM6, rs13256025 (8p21.2) in EBF2, rs11836164 (12p12.1) near SSPN, and rs17817449 (16q12.2) in FTO. We observed significant genetic correlations between V and mammographic dense area (r_g = 0.79, P = 5.91 × 10⁻⁵), percent density (r_g = 0.73, P = 1.00 × 10⁻⁴), and adult BMI (r_g =  − 0.36, P = 3.88 × 10⁻⁷). Additional significant relationships were observed for non-dense area (z =  − 4.14, P = 3.42 × 10⁻⁵), estrogen receptor-positive breast cancer (z = 3.41, P = 6.41 × 10⁻⁴), and childhood body fatness (z =  − 4.91, P = 9.05 × 10⁻⁷) from the SNP-set tests.

Conclusions

These findings provide new insights into the genetic basis of mammographic texture variation and their associations with MD, breast cancer risk, and other breast cancer risk factors.

Abstract PO-250: Impact of age, race, and family history on COVID-19 related changes in breast cancer screening among the Boston Mammography Cohort Study

The COVID-19 pandemic has placed an unprecedented burden on the healthcare system, disrupting routine care including breast cancer screening. We used data from 2392 women without a history of breast cancer enrolled in the Boston Mammography Cohort Study (BMCS) to investigate whether subgroups defined by age, race, or family history of breast cancer: 1) experienced greater declines in screening or diagnostic imaging during the lockdown; or 2) had slower rebound during reopening. In this interrupted time series analysis, we used Poisson regression with robust standard errors to model expected monthly rates of breast cancer screening and diagnostic imaging from January 2019 through December 2020. We defined the pre-COVID-19 period as January 1, 2019, to February 29, 2020; the lockdown period as March 1 to May 30, 2020; and the reopening period as June 1 to December 31, 2020. We examined changes in trends overall and tested for the difference in trends by age (&lt;50 vs ≤50), race (white vs non-white), and first-degree family history of breast cancer (yes or no). The mean monthly rate of breast cancer screening in the BMCS cohort was 45 per 1000 people during the pre-COVID-19 period, 7 per 1000 people during the lockdown period, and 50 per 1000 people during the reopening period. The mean monthly rate of breast cancer diagnostic imaging was 6 per 1000 people during the pre-COVID-19 period, 3 per 1000 people during the lockdown period, and 6 per 1000 people during the reopening period. During the pre-COVID-19 period, those who are age 50 or older had 5.3% higher monthly trend in breast cancer screening rates (p=0.005) and 9.8% higher monthly trend in diagnostic imaging rates (p=0.0389). During the lockdown period, those who were age 50 or older had a lower monthly trend in breast cancer screening rates compared to those who were younger than 50 (p&lt;0.0001), while those who were white and those with family history have higher monthly trends of breast cancer screening rates compared to their respective counterparts (p&lt;0.0001). During the reopening phase, those who are age 50 or older have 18.5% lower monthly trend in breast cancer screening rates in comparison to those who are younger than 50 (p=0.0008) and those who were white have 36.2% higher monthly trend in breast cancer diagnostic procedure rates in comparison to those who are non-white (p=0.018). Overall, we observed a significant decline in breast cancer screening rates with the advent of the COVID-19 pandemic. For the most part, screening and diagnostic imaging rates during the reopening phase equaled or exceeded those of the pre-COVID-19 period. However, the rate of return to screening was lower in women age 50 or older and the rebound in diagnostic imaging was lower in non-white women. Careful attention must be paid as the COVID-19 recovery continues to ensure equitable resumption of care. Future work will examine other factors including insurance status, breast cancer risk scores, and geographic location.

Internalized stigma among cancer patients enrolled in a smoking cessation trial: The role of cancer type and associations with psychological distress

PURPOSE

Cancer patients who smoke may experience significant stigma due both to their disease, and negative attitudes and beliefs regarding smoking. We investigated whether internalized stigma differed between currently smoking cancer patients diagnosed with lung or head and neck cancers, other smoking related cancers, and non smoking-related cancers, and whether internalized stigma was associated with psychological distress.

METHODS

This cross-sectional analysis used baseline data on 293 participants enrolled in a multi-site randomized smoking cessation intervention trial of patients with recently diagnosed cancer. Internalized stigma was assessed using five Internalized Shame items from the Social Impact of Disease Scale. Smoking-related cancers included lung, head and neck, esophageal, bladder, kidney, liver, pancreatic, colorectal, anal, small intestinal, gastric, and cervical. We used multivariable linear regression to examine whether mean internalized stigma levels differed between individuals with lung and head and neck cancers, other smoking-related cancers, and non smoking-related cancers, adjusting for potential confounders. We further examined the association of internalized stigma with depression, anxiety, and perceived stress, overall and among cancer type groups.

RESULTS

Thirty-nine percent of participants were diagnosed with lung or head and neck cancer, 21% with another smoking-related cancer, and 40% with a non smoking-related cancer. In multivariable-adjusted models, participants with lung or head and neck cancers (11.6, 95% confidence intervals (CI) = 10.8-12.2; p < 0.0001) or other smoking-related cancers (10.7, 95% CI = 9.8-11.7; p = 0.03) had higher mean internalized stigma scores compared to those non-smoking-related cancers (9.3, 95% CI = 8.6-10.0). We observed similar positive associations between internalized stigma and depressive symptoms, anxiety, and perceived stress among participants with smoking-related and non smoking-related cancers.

CONCLUSIONS

Among smokers, those with smoking-related cancers experienced the highest levels of internalized stigma, and greater internalized stigma was associated with greater psychological distress across cancer types. Providers should assess patients for internalized and other forms of stigma, refer patients for appropriate psychosocial support services, and address stigma in smoking cessation programs.

Imaging Evaluation of the Axilla-A National Survey of Clinical Practice Among Radiologists

OBJECTIVE

To assess awareness and implementation of the American College of Surgeons Oncology Group Z0011 trial findings, approaches to axillary nodal imaging, and to identify differences in practice based on respondent characteristics.

METHODS

An online survey was distributed to members of the Society of Breast Imaging. Questions regarded demographics, evaluation approaches, and impact of the Z0011 trial. Poisson regression with robust standard errors to regression was used to generate multivariable-adjusted relative risks and 95% confidence intervals (CIs) for associations.

RESULTS

The response rate was 21.7% (430/2007). The majority (295/430, 68.6%) reported always performing axillary US in patients with a BI-RADS 4B, 4C, or 5 breast mass. Most respondents (299/430, 69.5%) were familiar with the findings of the Z0011 trial. Radiologists in academic practice were 0.67 (95% CI: 0.54-0.83) times less likely than private practice radiologists to perform axillary US in all masses and 1.31 (95% CI: 1.13-1.52) times more likely to be very familiar with the trial. Frequency of axillary US showed no association with time spent in breast imaging, years in practice, or presence of dedicated breast surgeons. Increased time in breast imaging and presence of dedicated breast surgeons was strongly associated with familiarity with the trial. No association was observed with years in practice. Most respondents (291/430, 67.7%) made little or no change to their practice based on trial findings.

CONCLUSION

There is wide variability in approaches to axillary nodal evaluation, demonstrating a need for improved education and guidelines for axillary imaging in breast cancer patients.

Stress and spirituality in relation to HPA axis gene methylation among US Black women: results from the Black Women's Health Study and the Study on Stress, Spirituality and Health

Background: Few epigenetics studies have been conducted within the Black community to examine the impact of diverse psychosocial stressors and resources for resiliency on the stress pathway (hypothalamus-pituitary-adrenal axis). Methods: Among 1000 participants from the Black Women's Health Study, associations between ten psychosocial stressors and DNA methylation (DNAm) of four stress-related genes (NR3C1, HSDB1, HSD11B2 and FKBP5) were tested. Whether religiosity or spirituality (R/S) significantly modified these stress-DNAm associations was also assessed. Results: Associations were found for several stressors with DNAm of individual CpG loci and average DNAm levels across each gene, but no associations remained significant after false discovery rate (FDR) correction. Several R/S variables appeared to modify the relationship between two stressors and DNAm, but no identified interaction remained significant after FDR correction. Conclusion: There is limited evidence for a strong signal between stress and DNAm of hypothalamus-pituitary-adrenal axis genes in this general population cohort of US Black women.

The trajectory of racial/ethnic disparities in the use of cancer screening before and during the COVID-19 pandemic: A large U.S. academic center analysis

Cancer screening rates declined sharply early in the COVID-19 pandemic. The impact of the pandemic may have exacerbated existing disparities in cancer screening due to the disproportionate burden of illness and job loss among racial/ ethnic minorities, and potentially, uneven resumption of care between different racial/ ethnic groups. Using electronic health record data from Mass General Brigham (MGB), we assessed changes in rates of breast, cervical, colorectal and lung cancer screening before and during the pandemic. Among patients who received primary care in an MGB-affiliated primary care practice, cancer screening rates were calculated as the number of individuals who received a screening test for each cancer type over the number of individuals due for each test, during each month between April 2019-November 2020. We conducted an interrupted time-series analysis to test for changes in screening rates by race/ethnicity before and during the pandemic. Prior to the pandemic, relative to White individuals, Asian women were less likely to receive breast cancer screening (p < 0.001), and Latinx and Black individuals were less likely to screen for lung cancer (p < 0.001 and p = 0.02). Our results did not show significant improvement or worsening of racial/ethnic disparities for any cancer screening type as screening resumed. However, as of November 2020 rates of screening for breast cancer were lower than pre-pandemic levels for Latinx individuals, and lung cancer screening rates were higher than baseline for Latinx, Black or White individuals. Further monitoring of disparities in cancer screening is warranted as the pandemic evolves.

Race, ethnicity, community-level socioeconomic factors, and risk of COVID-19 in the United States and the United Kingdom

BACKGROUND

There is limited prior investigation of the combined influence of personal and community-level socioeconomic factors on racial/ethnic disparities in individual risk of coronavirus disease 2019 (COVID-19).

METHODS

We performed a cross-sectional analysis nested within a prospective cohort of 2,102,364 participants from March 29, 2020 in the United States (US) and March 24, 2020 in the United Kingdom (UK) through December 02, 2020 via the COVID Symptom Study smartphone application. We examined the contribution of community-level deprivation using the Neighborhood Deprivation Index (NDI) and the Index of Multiple Deprivation (IMD) to observe racial/ethnic disparities in COVID-19 incidence. ClinicalTrials.gov registration: NCT04331509.

FINDINGS

Compared with non-Hispanic White participants, the risk for a positive COVID-19 test was increased in the US for non-Hispanic Black (multivariable-adjusted odds ratio [OR], 1.32; 95% confidence interval [CI], 1.18-1.47) and Hispanic participants (OR, 1.42; 95% CI, 1.33-1.52) and in the UK for Black (OR, 1.17; 95% CI, 1.02-1.34), South Asian (OR, 1.39; 95% CI, 1.30-1.49), and Middle Eastern participants (OR, 1.38; 95% CI, 1.18-1.61). This elevated risk was associated with living in more deprived communities according to the NDI/IMD. After accounting for downstream mediators of COVID-19 risk, community-level deprivation still mediated 16.6% and 7.7% of the excess risk in Black compared to White participants in the US and the UK, respectively.

INTERPRETATION

Our results illustrate the critical role of social determinants of health in the disproportionate COVID-19 risk experienced by racial and ethnic minorities.

Association of social distancing and face mask use with risk of COVID-19

Given the continued burden of COVID-19 worldwide, there is a high unmet need for data on the effect of social distancing and face mask use to mitigate the risk of COVID-19. We examined the association of community-level social distancing measures and individual face mask use with risk of predicted COVID-19 in a large prospective U.S. cohort study of 198,077 participants. Individuals living in communities with the greatest social distancing had a 31% lower risk of predicted COVID-19 compared with those living in communities with poor social distancing. Self-reported 'always' use of face mask was associated with a 62% reduced risk of predicted COVID-19 even among individuals living in a community with poor social distancing. These findings provide support for the efficacy of mask-wearing even in settings of poor social distancing in reducing COVID-19 transmission. Despite mass vaccination campaigns in many parts of the world, continued efforts at social distancing and face mask use remain critically important in reducing the spread of COVID-19.

Religion, spirituality and diurnal rhythms of salivary cortisol and dehydroepiandrosterone in postmenopausal women

Background

Religion and spirituality (R/S) are important resources for coping with stress and are hypothesized to influence health outcomes via modulation of the hypothalamic-pituitary-adrenal (HPA) axis, though this has not been evaluated extensively. In this study, we examined associations between several measures of religiosity or spirituality (R/S) and three HPA axis biomarkers: cortisol, dehydroepiandrosterone (DHEA), and cortisol:DHEA ratio.

Methods

Sample included 216 female postmenopausal Nurses’ Health Study II participants who provided up to five timed saliva samples: immediately upon awakening, 45 min, 4 h, and 10 h after waking, and prior to going to sleep during a single day in 2013. Multivariable-adjusted linear mixed models with piecewise cubic spline functions and adjustment for potential covariates were used to estimate the cross-sectional associations of eight R/S measures with diurnal rhythms of cortisol, DHEA, and the cortisol/DHEA ratio.

Results

There was little evidence of association between the eight R/S measures analyzed and diurnal rhythms of cortisol, DHEA, and the cortisol/DHEA ratio. Women who reported that R/S was very involved in understanding or dealing with stressful situations had slower night rise in cortisol than those who did not. Greater levels of religious struggles were associated with higher cortisol levels throughout the day. Higher non-theistic daily spiritual experiences scores were associated with slower DHEA night rise, and a higher cortisol/DHEA ratio upon waking and at night. However, these associations were significantly attenuated when we excluded women reporting bedtimes at least 30 min later than usual.

Conclusion

Observed associations were driven by those with late sleep schedules, and given the number of comparisons made, could be due to chance. Future research using larger, more diverse samples of individuals is needed to better understand the relationship between R/S and HPA axis biomarkers.

•

We examined the influence of religion and spirituality on HPA-axis diurnal rhythms of cortisol, DHEA, and their ratio.

•

Religious coping, religious struggles, and non-theistic DSES were associated with modest alterations in HPA axis rhythms.

•

Observed associations were driven by those with late sleep schedules.

Automated percent mammographic density, mammographic texture variation, and risk of breast cancer: a nested case-control study

Percent mammographic density (PMD) is a strong breast cancer risk factor, however, other mammographic features, such as V, the standard deviation (SD) of pixel intensity, may be associated with risk. We assessed whether PMD, automated PMD (APD), and V, yielded independent associations with breast cancer risk. We included 1900 breast cancer cases and 3921 matched controls from the Nurses' Health Study (NHS) and the NHSII. Using digitized film mammograms, we estimated PMD using a computer-assisted thresholding technique. APD and V were determined using an automated computer algorithm. We used logistic regression to generate odds ratios (ORs) and 95% confidence intervals (CIs). Median time from mammogram to diagnosis was 4.1 years (interquartile range: 1.6-6.8 years). PMD (OR per SD:1.52, 95% CI: 1.42, 1.63), APD (OR per SD:1.32, 95% CI: 1.24, 1.41), and V (OR per SD:1.32, 95% CI: 1.24, 1.40) were positively associated with breast cancer risk. Associations for APD were attenuated but remained statistically significant after mutual adjustment for PMD or V. Women in the highest quartile of both APD and V (OR vs Q1/Q1: 2.49, 95% CI: 2.02, 3.06), or PMD and V (OR vs Q1/Q1: 3.57, 95% CI: 2.79, 4.58) had increased breast cancer risk. An automated method of PMD assessment is feasible and yields similar, but somewhat weaker, estimates to a manual measure. PMD, APD and V are each independently, positively associated with breast cancer risk. Women with dense breasts and greater texture variation are at the highest relative risk of breast cancer.

Racial and ethnic differences in COVID-19 vaccine hesitancy and uptake

BACKGROUND

Racial and ethnic minorities have been disproportionately impacted by COVID-19. In the initial phase of population-based vaccination in the United States (U.S.) and United Kingdom (U.K.), vaccine hesitancy and limited access may result in disparities in uptake.

METHODS

We performed a cohort study among U.S. and U.K. participants in the smartphone-based COVID Symptom Study (March 24, 2020-February 16, 2021). We used logistic regression to estimate odds ratios (ORs) of COVID-19 vaccine hesitancy (unsure/not willing) and receipt.

RESULTS

In the U.S. ( n =87,388), compared to White non-Hispanic participants, the multivariable ORs of vaccine hesitancy were 3.15 (95% CI: 2.86 to 3.47) for Black participants, 1.42 (1.28 to 1.58) for Hispanic participants, 1.34 (1.18 to 1.52) for Asian participants, and 2.02 (1.70 to 2.39) for participants reporting more than one race/other. In the U.K. ( n =1,254,294), racial and ethnic minorities had similarly elevated hesitancy: compared to White participants, their corresponding ORs were 2.84 (95% CI: 2.69 to 2.99) for Black participants, 1.66 (1.57 to 1.76) for South Asian participants, 1.84 (1.70 to 1.98) for Middle East/East Asian participants, and 1.48 (1.39 to 1.57) for participants reporting more than one race/other. Among U.S. participants, the OR of vaccine receipt was 0.71 (0.64 to 0.79) for Black participants, a disparity that persisted among individuals who specifically endorsed a willingness to obtain a vaccine. In contrast, disparities in uptake were not observed in the U.K.

CONCLUSIONS

COVID-19 vaccine hesitancy was greater among racial and ethnic minorities, and Black participants living in the U.S. were less likely to receive a vaccine than White participants. Lower uptake among Black participants in the U.S. during the initial vaccine rollout is attributable to both hesitancy and disparities in access.

A Genome-Wide Association Study of Childhood Body Fatness

OBJECTIVE

This study aimed to uncover genetic contributors to adiposity in early life.

METHODS

A genome-wide association study of childhood body fatness in 34,401 individuals within the Nurses' Health Studies and the Health Professionals Follow-up Study was conducted. Data were imputed to the 1000 Genomes Phase 3 version 5 reference panel.

RESULTS

A total of 1,354 single-nucleotide polymorphisms (P < 10^-4 ) were selected for replication in a previously published genome-wide association study of childhood BMI. Nineteen significant genome-wide (P < 5 × 10^-8 ) regions were observed, fourteen of which were previously associated with childhood obesity and five were novel: BNDF (P = 7.58 × 10^-13 ), PRKD1 (P = 1.43 × 10^-10 ), 20p13 (P = 2.05 × 10^-10 ), FHIT (P = 1.77 × 10^-8 ), and LOC101927575 (P = 3.22 × 10^-8 ). The BNDF, FHIT, and PRKD1 regions were previously associated with adult BMI. LOC101927575 and 20p13 regions have not previously been associated with adiposity phenotypes. In a transcriptome-wide analysis, associations for POMC at 2p23.3 (P = 3.36 × 10^-6 ) and with TMEM18 at 2p25.3 (P = 3.53 × 10^-7 ) were observed. Childhood body fatness was genetically correlated with hip (r_g = 0.42, P = 4.44 × 10^-16 ) and waist circumference (r_g = 0.39, P = 5.56 × 10^-16 ), as well as age at menarche (r_g = -0.37, P = 7.96 × 10^-19 ).

CONCLUSIONS

Additional loci that contribute to childhood adiposity were identified, further explicating its genetic architecture.

Abstract PO-077: Impact of COVID-19 on patient navigation for cancer treatment

Patient navigation has been shown to improve cancer care in underserved populations. Since November 2017, we have enrolled newly diagnosed cancer patients from three community health centers into a patient navigation study. Most of our patients receive primary care in Chelsea, a city that had the highest rate of COVID-19 infection in Massachusetts. The goal of this analysis was to explore the impact of COVID-19 on patient navigation and care utilization during active cancer treatment. Methods: Our analysis examined two time periods: prior to the COVID-19 pandemic in Massachusetts (November 2017 – February 2020) and during the pandemic (March – June 2020). We used bivariate Poisson regression to examine whether the number of patients per month recruited to our study, or the number of patient navigators’ interventions per month differed between these periods. We used chi-square tests to compare the proportion of cancer treatment appointments completed, missed (no shows), or cancelled prior to and during the COVID-19 pandemic. Attended appointment rate was defined as completed appointments of scheduled (including cancelled) appointments. Results: Of 201 patients enrolled, 47% were women, 27% self-identified as Hispanic or Latino, 7% as Black or African American, 3% as Asian, 20% as other and 30% did not speak English. Prior to COVID- 19, 178 patients (6.36/per month) enrolled in patient navigation compared to 23 (5.75/per month) during COVID-19 (p=0.65). Prior to COVID-19, 3425 of 4040 (84.8%) total appointments were attended compared to 391 of 511 (76.5%) during COVID-19 (p&lt;0.0001). Prior to COVID-19, there were 115 missed appointments (2.9%) compared to 15 missed appointments (2.9%) during COVID-19 (p=0.91). Prior to COVID-19, 500 appointments were cancelled (12.4%) compared to 105 appointments (20.6%) during COVID-19 (p&lt;0.0001). Total number of navigators’ interventions prior to COVID-19 was 1846 (65.9/per month) compared to 650 (162.5/per month) during COVID-19 (p&lt;0.0001). Conclusion: Underserved cancer patients successfully enrolled into a patient navigation program during the COVID-19 pandemic at rates similar to prior to COVID-19. During COVID-19, the proportion of attended appointments dropped, due to more cancelled appointments (likely both institution and patient driven). Although navigators could not provide in-person navigation during COVID- 19, they performed substantially more interventions per month. There was no change in rate of missed appointments with only 2.9% of cancer appointments missed during COVID-19 suggesting that navigation during COVID-19 was effective in reducing missed appointments in a patient population including underserved communities at the epicenter of the COVID-19 pandemic. Patient navigation may be a promising strategy to ensure cancer care for underserved patients during public health crises such as COVID-19.

Association of social distancing and masking with risk of COVID-19

Given the continued burden of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) disease (COVID-19) across the U.S., there is a high unmet need for data to inform decision-making regarding social distancing and universal masking. We examined the association of community-level social distancing measures and individual masking with risk of predicted COVID-19 in a large prospective U.S. cohort study of 198,077 participants. Individuals living in communities with the greatest social distancing had a 31% lower risk of predicted COVID-19 compared with those living in communities with poor social distancing. Self-reported masking was associated with a 63% reduced risk of predicted COVID-19 even among individuals living in a community with poor social distancing. These findings provide support for the efficacy of mask-wearing even in settings of poor social distancing in reducing COVID-19 transmission. In the current environment of relaxed social distancing mandates and practices, universal masking may be particularly important in mitigating risk of infection.

Physical and sexual abuse in childhood and adolescence and leukocyte telomere length: A pooled analysis of the study on psychosocial stress, spirituality, and health

Introduction

We examined whether abuse in childhood and/or adolescence was associated with shorter telomere length in a pooled analysis of 3,232 participants from five diverse cohorts. We also assessed whether religion or spirituality (R/S) could buffer deleterious effects of abuse.

Methods

Physical and sexual abuse in childhood (age <12) and adolescence (age 12–18) was assessed using the Revised Conflict Tactics Scale and questions from a 1995 Gallup survey. We measured relative leukocyte telomere lengths (RTL) using quantitative real time polymerase chain reaction. We used generalized estimating equations to assess associations of physical and sexual abuse with log-transformed RTL z-scores. Analyses were conducted in each cohort, overall, and stratified by extent of religiosity or spirituality and religious coping in adulthood. We pooled study‐specific estimates using random‐effects models and assessed between-study heterogeneity.

Results

Compared to no abuse, severe sexual abuse was associated with lower RTL z-scores, in childhood: -15.6%, 95% CI: -25.9, -4.9; p-trend = 0.04; p-heterogeneity = 0.58 and in adolescence: -16.5%, 95% CI: -28.1, -3.0; p-trend = 0.08; p-heterogeneity = 0.68. Sexual abuse experienced in both childhood and adolescence was associated with 11.3% lower RTL z-scores after adjustment for childhood and demographic covariates (95% CI: -20.5%, -2.0%; p-trend = 0.03; p-heterogeneity = 0.62). There was no evidence of effect modification by R/S. Physical abuse was not associated with telomere length.

Conclusions

Sexual abuse in childhood or adolescence was associated with a marker of accelerated biological aging, decreased telomere length. The lack of moderation by R/S may be due to inability to capture the appropriate time period for those beliefs and practices.

Abstract S11-02: Patient-reported impact of the COVID-19 pandemic on breast cancer screening, diagnosis, and treatment: A national survey

Introduction: The COVID-19 pandemic has altered the health care delivery system. The purpose of this study was to determine the impact of the COVID-19 pandemic on breast cancer screening, diagnosis, and treatment.

Methods: Potential survey respondents were identified through partnerships with breast cancer organizations including Dr. Susan Love Foundation for Breast Cancer Research, SHARE, Survivingbreastcancer.org, Sisters Network Inc., the African American Breast Cancer Alliance, and through ResearchMatch.org. Study information was shared via social media, websites, or email. Individuals were eligible for this study if they: 1) receive routine breast cancer screening, or 2) are undergoing diagnostic evaluation for breast cancer, or 3) had ever been diagnosed with breast cancer. Participants accessed and completed the 10-15-minute REDCap survey either by emailing the research team and receiving a private survey link or by clicking a public link. The survey collected information on respondent demographics; breast cancer screening and diagnosis; the extent to which screening, diagnosis, or treatment had been changed, delayed, or canceled because of COVID-19; personal protective practices; extent of worry about financial and health implications of COVID-19; and use of telemedicine. We used descriptive statistical analyses to better understand the impact of the COVID-19 pandemic on respondents.

Results: There are currently 415 survey respondents, 404 of whom agreed to participate in the study. 46.8% (N=189) of respondents were white, 26.7% (N=108) Black, 6.7% (N=27) Asian, and 5.5% Hispanic or Latino (N=22). Most respondents were between the ages of 50 and 69 years (52.2%, N=211). 43.3% (N=175) of respondents had been diagnosed with breast cancer and, of those, 36% (N=63) were in active treatment. More than a quarter of participants (26.5%, N=107) reported delayed or canceled breast cancer care due to COVID-19; the most frequently affected care was screening mammogram, ultrasound, or MRI (97.2%, N=104). 20.6% (N=13) of women in active treatment reported delayed or canceled surgery, chemotherapy, or radiation visits. 22.3% (N=90) of respondents reported that an in-person visit was changed to a phone call or videoconference, and 39.1% (N=158) said they had discussed COVID-19 with a health care provider. 29.1% (N=51) of those with breast cancer were worried or very worried that the COVID-19 pandemic would make it harder for them to get cancer care; among those without breast cancer, 34.9% (N=80) were worried that COVID-19 would make it harder to obtain health care, including breast cancer screening and diagnosis.

Conclusions: The COVID-19 pandemic continues to disrupt breast cancer-related care, primarily screening. Planning and coordination are necessary to ensure the timely return of these patients to care. Most participants agreed to be contacted for follow-up, allowing us to investigate the long-term effects of delayed breast cancer screening, diagnostic evaluation, and treatment on health outcomes.

Risk of COVID-19 among front-line health-care workers and the general community: a prospective cohort study

BACKGROUND

Data for front-line health-care workers and risk of COVID-19 are limited. We sought to assess risk of COVID-19 among front-line health-care workers compared with the general community and the effect of personal protective equipment (PPE) on risk.

METHODS

We did a prospective, observational cohort study in the UK and the USA of the general community, including front-line health-care workers, using self-reported data from the COVID Symptom Study smartphone application (app) from March 24 (UK) and March 29 (USA) to April 23, 2020. Participants were voluntary users of the app and at first use provided information on demographic factors (including age, sex, race or ethnic background, height and weight, and occupation) and medical history, and subsequently reported any COVID-19 symptoms. We used Cox proportional hazards modelling to estimate multivariate-adjusted hazard ratios (HRs) of our primary outcome, which was a positive COVID-19 test. The COVID Symptom Study app is registered with ClinicalTrials.gov, NCT04331509.

FINDINGS

Among 2 035 395 community individuals and 99 795 front-line health-care workers, we recorded 5545 incident reports of a positive COVID-19 test over 34 435 272 person-days. Compared with the general community, front-line health-care workers were at increased risk for reporting a positive COVID-19 test (adjusted HR 11·61, 95% CI 10·93-12·33). To account for differences in testing frequency between front-line health-care workers and the general community and possible selection bias, an inverse probability-weighted model was used to adjust for the likelihood of receiving a COVID-19 test (adjusted HR 3·40, 95% CI 3·37-3·43). Secondary and post-hoc analyses suggested adequacy of PPE, clinical setting, and ethnic background were also important factors.

INTERPRETATION

In the UK and the USA, risk of reporting a positive test for COVID-19 was increased among front-line health-care workers. Health-care systems should ensure adequate availability of PPE and develop additional strategies to protect health-care workers from COVID-19, particularly those from Black, Asian, and minority ethnic backgrounds. Additional follow-up of these observational findings is needed.

Stress-Associated Neurobiological Pathway Linking Socioeconomic Disparities to Cardiovascular Disease

BACKGROUND

Lower socioeconomic status (SES) associates with a higher risk of major adverse cardiac events (MACE) via mechanisms that are not well understood.

OBJECTIVES

Because psychosocial stress is more prevalent among those with low SES, this study tested the hypothesis that stress-associated neurobiological pathways involving up-regulated inflammation in part mediate the link between lower SES and MACE.

METHODS

A total of 509 individuals, median age 55 years (interquartile range: 45 to 66 years), underwent clinically indicated whole-body ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography imaging and met pre-defined inclusion criteria, including absence of known cardiovascular disease or active cancer. Baseline hematopoietic tissue activity, arterial inflammation, and in a subset of 289, resting amygdalar metabolism (a measure of stress-associated neural activity) were quantified using validated ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography methods. SES was captured by neighborhood SES factors (e.g., median household income and crime). MACE within 5 years of imaging was adjudicated.

RESULTS

Over a median 4.0 years, 40 individuals experienced MACE. Baseline income inversely associated with amygdalar activity (standardized β: -0.157 [95% confidence interval (CI): -0.266 to -0.041]; p = 0.007) and arterial inflammation (β: -0.10 [95% CI: -0.18 to -0.14]; p = 0.022). Further, income associated with subsequent MACE (standardized hazard ratio: 0.67 [95% CI: 0.47 to 0.96]; p = 0.029) after multivariable adjustments. Mediation analysis demonstrated that the path of: ↓ neighborhood income to ↑ amygdalar activity to ↑ bone marrow activity to ↑ arterial inflammation to ↑ MACE was significant (β: -0.01 [95% CI: -0.06 to -0.001]; p < 0.05).

CONCLUSIONS

Lower SES: 1) associates with higher amygdalar activity; and 2) independently predicts MACE via a serial pathway that includes higher amygdalar activity, bone marrow activity, and arterial inflammation. These findings illuminate a stress-associated neurobiological mechanism by which SES disparities may potentiate adverse health outcomes.

Acceptability of an Interactive Computer-Animated Agent to Promote Patient-Provider Communication About Breast Density: a Mixed Method Pilot Study

BACKGROUND

Half of women undergoing mammography have dense breasts. Mandatory dense breast notification and educational materials have been shown to confuse women, rather than empower them.

OBJECTIVE

This study used a mixed method, multi-stakeholder approach to assess acceptability of an interactive, computer-animated agent that provided breast density information to women and changes in knowledge, satisfaction, and informational needs.

DESIGN

A pre-post survey and qualitative focus groups assessed the acceptability of the computer-animated agent among women. An anonymous, online survey measuring acceptability was delivered to a multi-stakeholder group.

PARTICIPANTS

English-speaking, mammography-eligible women ages 40-74 were invited and 44 women participated in one of nine focus groups. In addition, 14 stakeholders representing primary care, radiology, patient advocates, public health practitioners, and researchers completed the online survey.

INTERVENTIONS

A prototype of a computer-animated agent was delivered to women in a group setting; stakeholders viewed the prototype independently.

MAIN MEASURES

Data collected included open-ended qualitative questions that guided discussion about the content and form of the computer-animated agent. Structured surveys included domains related to knowledge, acceptability, and satisfaction. Stakeholder acceptability was measured with a series of statements about aspects of the intervention and delivery approach and are reported as the proportion of respondents who endorsed each statement.

KEY RESULTS

Six of 12 knowledge items demonstrated improvement post-intervention, satisfaction with the agent was high (81%), but the number of unanswered questions did not improve (67% vs. 54%, p = 0.37). Understanding of the distinction between connective and fatty tissue in the breast did not increase (30% vs. 26%, p = 0.48). Results of the multi-stakeholder survey suggest broad acceptability of the approach and agent.

CONCLUSIONS

Findings highlight the benefits of a brief interactive educational exposure as well as misperceptions that persisted. Results demonstrate the need for an evidence-based, accessible intervention that is easy to understand for patients.

Religious Service Attendance, Religious Coping, and Risk of Hypertension in Women Participating in the Nurses' Health Study II

The association between religious service attendance, religious coping, and hypertension is unclear. Prospective research and assessment of potential mediators is needed to understand this relationship. From 2001-2013, we prospectively followed 44,281 nonhypertensive women who provided information on religious service attendance and religious coping in the Nurses' Health Study II. Cox regression and mediation analyses were conducted to assess associations between religion and hypertension. There were 453,706 person-years of follow-up and 11,773 incident hypertension cases. Women who attended religious services were less likely to develop hypertension. In the fully adjusting model, compared with women who never or almost never attend religious meetings or services, women attending less than once per month (hazard ratio (HR) = 0.97, 95% confidence interval (CI): 0.91, 1.03), 1-3 times per month (HR = 0.94, 95% CI: 0.88, 1.00), once per week (HR = 0.93, 95% CI: 0.88, 0.98), or more than once per week (HR = 0.91, 95% CI: 0.86, 0.97) showed a decreased risk of hypertension (P for trend = 0.001). Body mass index was an important mediator (11.5%; P < 0.001). Religious coping had a marginal association with hypertension. In conclusion, religious service attendance was modestly associated with hypertension in an inverse dose-response manner and partially mediated through body mass index. Future research is needed on biological or social reasons for the lower risk of hypertension.

Early-Life and Adult Anthropometrics in Relation to Mammographic Image Intensity Variation in the Nurses' Health Studies

BACKGROUND

The V measure captures grayscale intensity variation on a mammogram and is positively associated with breast cancer risk, independent of percent mammographic density (PMD), an established marker of breast cancer risk. We examined whether anthropometrics are associated with V, independent of PMD.

METHODS

The analysis included 1,700 premenopausal and 1,947 postmenopausal women without breast cancer within the Nurses' Health Study (NHS) and NHSII. Participants recalled their body fatness at ages 5, 10, and 20 years using a 9-level pictogram (level 1: most lean) and reported weight at age 18 years, current adult weight, and adult height. V was estimated by calculating standard deviation of pixels on screening mammograms. Linear mixed models were used to estimate beta coefficients (ß) and 95% confidence intervals (CI) for the relationships between anthropometric measures and V, adjusting for confounders and PMD.

RESULTS

V and PMD were positively correlated (Spearman r = 0.60). Higher average body fatness at ages 5 to 10 years (level ≥ 4.5 vs. 1) was significantly associated with lower V in premenopausal (ß = -0.32; 95% CI, -0.48 to -0.16) and postmenopausal (ß = -0.24; 95% CI, -0.37 to -0.10) women, independent of current body mass index (BMI) and PMD. Similar inverse associations were observed with average body fatness at ages 10 to 20 years and BMI at age 18 years. Current BMI was inversely associated with V, but the associations were largely attenuated after adjustment for PMD. Height was not associated with V.

CONCLUSIONS

Our data suggest that early-life body fatness may reflect lifelong impact on breast tissue architecture beyond breast density. However, further studies are needed to confirm the results.

IMPACT

This study highlights strong inverse associations of early-life adiposity with mammographic image intensity variation.
