The impact of social constraints on insomnia among African-American breast cancer survivors: The mediating role of fear of recurrence.

OBJECTIVE: Insomnia is a significant concern among African-American breast cancer survivors (BCS). Social constraints (SC)-receiving unsupportive or critical responses when expressing trauma-related emotions-and fear of recurrence (FOR) have been associated with insomnia. We examined FOR as a mediator in the relationship between SC and insomnia in African-American BCS. We hypothesized a direct effect of SC on insomnia, and an indirect effect of SC on insomnia through FOR. METHODS: Sixty-four African-American BCS completed a questionnaire assessing demographics, clinical characteristics, SC, FOR, and insomnia. Participants were an average of M = 8.41 (SD = 5.8) year survivors. The mediation was tested using PROCESS for SPSS. RESULTS: The direct effect of SC on insomnia was significant (direct effect = .17, SE = .08, P = .04). Moreover, the indirect effect of SC on insomnia through FOR was significant (indirect effect = .19, SE = .10, 95% CI = .05, .41). CONCLUSIONS: Experiencing SC from family and friends could produce cognitions that impact sleep for BCS, and FOR could be one of those cognitions. Family-based models of care that emphasize the emotional needs of survivors and families could be a relevant strategy to address the SC that impacts sleep.

Using Patients' Social Network to Improve Compliance to Outpatient Screening Colonoscopy Appointments Among Blacks: A Randomized Clinical Trial.

OBJECTIVES: Patient navigation improves colorectal cancer screening among underserved populations, but limited resources preclude widespread adoption in minority-serving institutions. We evaluated whether a patient's self-selected social contact person can effectively facilitate outpatient screening colonoscopy. METHODS: From September 2014 to March 2017 in an urban tertiary center, 399 black participants scheduled for outpatient screening colonoscopy self-selected a social contact person to be a facilitator and provided the person's phone number. Of these, 201 participants (50.4%) were randomly assigned to the intervention arm for their social contact persons to be engaged by phone. The study was explained to the social contact person with details about colonoscopy screening and bowel preparation process. The social contacts were asked to assist the participants, provide support, and encourage compliance with the procedures. The social contact person was not contacted in the usual care arm, n = 198 (49.6%). We evaluated attendance to the scheduled outpatient colonoscopy and adequacy of bowel preparation. Analysis was performed by intention to treat. RESULTS: The social contact person was reached and agreed to be involved for 130 of the 201 participants (64.7%). No differences were found in the proportion of participants who underwent screening colonoscopy (77.3% vs 77.2%; relative risk = 1.01; 95% confidence interval: 0.91-1.12), but there was a modest increase in the proportion with adequate bowel preparation with social contact involvement (89.1% vs 80.9%; relative risk = 1.10; 95% confidence interval: 1.00-1.21). DISCUSSION: Engaging a patient's social network to serve in the role of a patient navigator did not improve compliance to outpatient screening colonoscopy but modestly improved the adequacy of bowel preparation.

Factors associated with attendance to scheduled outpatient endoscopy.

BACKGROUND: Non-attendance of 42% has been reported for outpatient colonoscopy among persons with low socioeconomic status (SES) in an open access system in the USA. OBJECTIVES: To evaluate attendance to outpatient endoscopy among populations with low SES after inperson consultations with endoscopists prior to scheduling. METHODS: Retrospectively, we reviewed the endoscopy schedule from September 2009 to August 2010 in an inner city teaching hospital in Washington, DC. We identified patients who came for their procedures. We defined non-attendance as when patients did not notify the facility up to 24 h prior to their scheduled procedures and did not show up. RESULTS: A total of 3304 patients were scheduled for outpatient endoscopy (mean age 55.2 years; 59.5% women). Only 36 (1.1%) patients were uninsured. 716 (21.7%) patients did not show up for their procedures. There were no differences in attendance by age, sex and race. Patients seen in a private endoscopist's office (OR=1.47; 95% CI 1.07 to 2.04) were more likely to attend when compared with patients seen in trainees' continuity clinic. Married patients (OR=1.40; 95% CI 1.11 to 1.78) were also more likely to attend. Conversely, Medicaid and uninsured patients were less likely to attend. Restricting our analysis to patients scheduled for only colonoscopy yielded similar results except that patients aged 50 years and older were more likely to attend. CONCLUSIONS: Our study suggests improved attendance to endoscopy when populations with lower SES undergo prior consultation with an endoscopist. There is a potential to further improve attendance to outpatient endoscopy by directly involving the social support of the patients.

An exploratory analysis of fear of recurrence among African-American breast cancer survivors.

BACKGROUND: Fear of recurrence (FOR) is a psychological concern that has been studied extensively in cancer survivors but has not been adequately examined in African-American breast cancer survivors. PURPOSE: This exploratory study describes the extent and nature of FOR in African-American breast cancer survivors. FOR is examined in relation to socio-demographic characteristics, treatment-related characteristics, psychological distress, and quality of life (QOL). METHODS: Participants completed questionnaires assessing FOR, psychological distress, QOL, and demographic and treatment characteristics. Pearson r correlations, t tests, and ANOVAs were used to determine the association between FOR and demographic and treatment-related characteristics. Hierarchical multiple regression models were performed to investigate the degree to which FOR dimensions account for the variance in QOL and psychological distress. RESULTS: Fifty-one African-American breast cancer survivors participated in this study. The mean age of participants was 64.24 (SD = 12.3). Overall fears as well as concerns about death and health were rated as low to moderate. Role worries and womanhood worries were very low. Inverse relationships were observed between age and FOR dimensions. FOR was positively correlated with measures of psychological distress and negatively correlated with QOL. FOR significantly accounted for a portion of the variance in QOL and distress after controlling for other variables. CONCLUSIONS: This study suggests that African-American women in this sample demonstrated some degree of FOR. Results indicate that FOR among African-American breast cancer survivors decreases with age and time since diagnosis and co-occurs with psychological distress as well as diminished quality of life.

A Feasibility Study of Smoking Cessation Utilizing an Exercise Intervention among Black Women: 'Quit and Fit'.

BACKGROUND: Women who engage in higher levels of exercise while trying to quit smoking have been shown to be less likely to relapse and to sustain their smoking abstinence longer. This study sought to examine the benefits of exercise for improving smoking cessation among Black women. METHODS: We evaluated the feasibility of a 12-week smoking and exercise intervention, Quit and Fit, tailored for Black women. All participants (intervention and control) received 12 weeks of smoking cessation counseling via telephone and 9 weeks of nicotine lozenges. Participants who were randomly assigned to the intervention condition were also assigned to a 12-week exercise group. RESULTS: Thirty-eight women were enrolled and 27 completed a 12-week follow-up assessment. Women from the intervention group were more likely to complete the 12-week follow-up assessment compared to participants in the control group (80% vs. 61%). Overall, 7 of the 38 participants (18%) were abstinent at 12 weeks (biochemically verified by expired carbon monoxide). Among the 25 women who completed the 12-week follow-up, abstinence was reported in 33% of the intervention group and 20% of the control group. Using an intent-to-treat approach, 25% of women in the intervention group were abstinent at 12 weeks (n = 5), compared to 11.1% for the control group (n = 2). These differences were not statistically significant. CONCLUSIONS: The overall retention rate was 71% (27/38) at 12 weeks with higher among the intervention group (16/20; 80%) compared to the control group (11/18; 61%). The study demonstrates that it is feasible to retain African-American women in a short-term study of smoking cessation and exercise.

It should not require a pandemic to make community engagement in research leadership essential, not optional.

Efforts to move community engagement in research from marginalized to mainstream include the NIH requiring community engagement programs in all Clinical and Translational Science Awards (CTSAs). However, the COVID-19 pandemic has exposed how little these efforts have changed the dominant culture of clinical research. When faced with the urgent need to generate knowledge about prevention and treatment of the novel coronavirus, researchers largely neglected to involve community stakeholders early in the research process. This failure cannot be divorced from the broader context of systemic racism in the US that has contributed to Black, Indigenous, and People of Color (BIPOC) communities bearing a disproportionate toll from COVID-19, being underrepresented in COVID-19 clinical trials, and expressing greater hesitancy about COVID-19 vaccination. We call on research funders and research institutions to take decisive action to make community engagement obligatory, not optional, in all clinical and translational research and to center BIPOC communities in this process. Recommended actions include funding agencies requiring all research proposals involving human participants to include a community engagement plan, providing adequate funding to support ongoing community engagement, including community stakeholders in agency governance and proposal reviews, promoting racial and ethnic diversity in the research workforce, and making a course in community engaged research a requirement for Masters of Clinical Research curricula.

Comparison of patterns of laxative ingestion to improve bowel preparation for colonoscopy: a pilot randomized clinical trial.

Background and study aims Negative experiences with bowel preparation are a barrier to uptake of colonoscopy. The aim of this study was to examine the impact of different flavoring of polyethylene glycol (PEG) laxatives on patient satisfaction with and adequacy of bowel preparation during colonoscopy. Patients and methods This was a single-blind (endoscopist), parallel design, randomized trial (NCT02062112) during which patients scheduled for colonoscopy were assigned to one of three groups: Group 1 (no laxative flavoring, n = 84); Group 2 (flavored entire laxative, n = 90) and Group 3 (tasted PEG with and without flavoring and decided how they want to drink the rest of the laxatives (choice group), n = 82). Patients rated their bowel preparation experience (satisfaction) and endoscopists accessed adequacy of bowel preparation during colonoscopy. Results There were no differences in patient ratings across the groups (1, 2 and 3) in taste of the laxatives ( P  = 0.67), ease of drinking ( P  = 0.53), and overall experience of bowel preparation process ( P  = 0.18). However, higher percentage of patients in the choice group would want the same laxative again if they were going to have a repeat colonoscopy in the future (72.5 % vs 81.3 % vs 88.9 %, P  = 0.04). Surprisingly, adequacy of bowel preparation was highest among patients who drank their PEG unflavored (89.3 % vs 80 % vs 75.5 %, P  = 0.07) and the had highest rates of adenoma detection (40.5 % vs 23.3 vs 39.0, P  = 0.03). Conclusions There were no differences in overall tolerability of bowel preparation by patterns of flavoring of PEG. Those who drank unflavored PEG were less satisfied but had better clinical outcome, suggesting minimum justification effect in bowel preparation process.

An assessment of the CES-D scale factor structure in black women: The Black Women's Health Study.

This study investigates the dimensional structure of the Center for Epidemiologic Studies Depression (CES-D) scale in US Black women with and without history of cancer via single-group and multi-group analyses. The CES-D questionnaire was administered in 1999 to 50,774 black women who are participants in the Black Women's Health Study (BWHS). For our analysis, we utilized a group of 690 women with a history of at least one of the three types of cancer (breast cancer, colon cancer or lung cancer) and an age-matched group of 1,380 healthy women with no history of any cancer or other chronic conditions including myocardial infarctions, stroke, angina, diabetes, lupus, and sarcoidosis. Three a priori hypothesized models were tested via confirmatory factor analysis: single-, three- and four-factor structures. The four-factor model provided the best fit and remained largely invariant across the groups when tested via multi-group comparisons. Two internal consistency measures of the scale (Cronbach's alpha coefficient and split-half coefficient) were also shown to be satisfactory. We concluded that the CES-D scale is appropriate for use in black women regardless of their cancer status.

CES-D four-factor structure is confirmed, but not invariant, in a large cohort of African American women.

This study examined the factor structure of the Centers for Epidemiologic Studies Depression Scale (CES-D) in a sample of 40,403 African American women participating in the Black Women's Health Study (BWHS). To examine within group differences in the structural characteristics of the CES-D, women were stratified by age (< 60 vs. > or = 60 years). Confirmatory factor analysis indicated that a four-factor solution was a good fit for the data in both groups. The four factors extracted (depressed, somatic, positive, and interpersonal) matched findings from previous studies in other populations. Although item loadings were identical for 19 of 20 items, when equality restrictions were placed on factor loadings, the factors were not shown to be equivalent across groups. The only observed difference in item loadings was that the item "people disliked me" loaded higher on the interpersonal factor for younger women than older women. The variance/covariance matrix differed between groups. The correlations between the depressed and somatic factors were identical for the two age groups. However, correlations among the other factors were weaker among older women. We conclude that four-factor structure of the CES-D is supported for African American women, but the relationships among the factors vary with age.

Beverage intake preference and bowel preparation laxative taste preference for colonoscopy.

AIM: To examine whether non-alcoholic beverage intake preferences can guide polyethylene glycol (PEG)-based bowel laxative preparation selection for patients. METHODS: We conducted eight public taste test sessions using commercially procured (A) unflavored PEG, (B) citrus flavored PEG and (C) PEG with ascorbate (Moviprep). We collected characteristics of volunteers including their beverage intake preferences. The volunteers tasted the laxatives in randomly assigned orders and ranked the laxatives as 1(st), 2(nd), and 3(rd) based on their taste preferences. Our primary outcome is the number of 1(st) place rankings for each preparation. RESULTS: A total of 777 volunteers completed the study. Unflavored PEG was ranked as 1(st) by 70 (9.0%), flavored PEG by 534 (68.7%) and PEG with ascorbate by 173 (22.3%) volunteers. Demographic, lifestyle characteristics and beverage intake patterns for coffee, tea, and carbonated drinks did not predict PEG-based laxative preference. CONCLUSION: Beverage intake pattern was not a useful guide for PEG-based laxative preference. It is important to develop more tolerable and affordable bowel preparation laxatives for colonoscopy. Also, patients should taste their PEG solution with and without flavoring before flavoring the entire gallon as this may give them more opportunity to pick a pattern that may be more tolerable.

Race and colorectal cancer screening compliance among persons with a family history of cancer.

AIM: To determine compliance to colorectal cancer (CRC) screening guidelines among persons with a family history of any type of cancer and investigate racial differences in screening compliance. METHODS: We used the 2007 Health Information National Trends Survey and identified 1094 (27.4%) respondents (weighted population size = 21959672) without a family history of cancer and 3138 (72.6%) respondents (weighted population size = 58201479) with a family history of cancer who were 50 years and older. We defined compliance with CRC screening as the use of fecal occult blood testing within 1 year, sigmoidoscopy within 5 years, or colonoscopy within 10 years. We compared compliance with CRC screening among those with and without a family member with a history of cancer. RESULTS: Overall, those with a family member with cancer were more likely to be compliant with CRC screening (64.9% vs 55.1%; OR = 1.45; 95%CI: 1.20-1.74). The absolute increase in screening rates associated with family history of cancer was 8.2% among whites. Hispanics had lowest screening rates among those without family history of cancer 41.9% but had highest absolute increase (14.7%) in CRC screening rate when they have a family member with cancer. Blacks had the lowest absolute increase in CRC screening (5.3%) when a family member has a known history of cancer. However, the noted increase in screening rates among blacks and Hispanics when they have a family member with cancer were not higher than whites without a family history of cancer: (54.5% vs 58.7%; OR = 1.16; 95%CI: 0.72-1.88) for blacks and (56.7% vs 58.7%; OR = 1.25; 95%CI: 0.72-2.18) for Hispanics. CONCLUSION: While adults with a family history of any cancer were more likely to be compliant with CRC screening guidelines irrespective of race/ethnicity, blacks and Hispanics with a family history of cancer were less likely to be compliant than whites without a family history. Increased burden from CRC among blacks may be related to poor uptake of screening among high-risk groups.

Effect of lung cancer screening awareness on smoking cessation behavior.

BACKGROUND AND OBJECTIVES: Emphasizing the risk of lung cancer can encourage smoking cessation; however, computerized tomography (CT) scans reduced lung cancer mortality in a recent randomized screening trial. We postulated that awareness of lung cancer screening test will negatively impact smoking cessation behavior. METHODS: We identified 7,141 respondents who answered questions concerning their smoking-related behavior in the 2007 Health Information National Trends Survey (HINTS). We used survey weights in all analyses and used logistic regression models to assess the association of smoking status with awareness of lung cancer screening tests and evaluated smoking cessation behaviors. RESULTS: Overall, 2,183 (27.6%) of respondents had heard of a lung cancer screening test (26.9% among never smokers, 29.6% among former smokers, and 27.1% among current smokers). Smoking status was not associated with awareness of lung cancer screening tests. Among current smokers, awareness of lung cancer screening had no effect on quit attempts in the previous 12 months (OR=1.14, 95% CI=0.68-1.91) and consideration to quit in the next 6 months (OR=1.08; 95% CI=0.69-1.67). CONCLUSIONS: Smoking cessation should be recommended for all current smokers, and those with a history of smoking should be informed about lung cancer screening with CT scan.

Cigarillo use among high-risk urban young adults.

In the U.S., cigar use doubled from 5.0 to 10.6 billion cigars consumed annually between 1997 and 2007, driven in large part by increased sales of cigarette-sized "little cigars" and narrow, mid-sized "cigarillos." The present study examined prevalence of cigarillo use as well as attitudes, knowledge and behaviors related to cigarillo use among a sample of predominantly urban African American young adults 18-24 not in school and not employed. Survey data were collected from 131 young adults attending education and job training centers in Baltimore, Maryland and from 78 young adults attending education, job training, or recreational programs in Washington, D.C. In Baltimore, 22% of young adults had smoked a cigarillo in the past 30 days, compared with nearly 63% in D.C. Both populations were heavily exposed to cigarillo advertising and marketing. Cigarillo use in this urban young adult population is a growing public health problem and undermines the progress made in decreasing cigarette use.

Antidepressant use, depressive symptoms, and incident frailty in women aged 65 and older from the Women's Health Initiative Observational Study.

OBJECTIVES: To examine the associations between depressive symptoms, antidepressant use, and duration of use with incident frailty 3 years later in nonfrail women aged 65 and older. DESIGN: Secondary analysis of the Women's Health Initiative Observational Study (WHI-OS), a prospective cohort study. SETTING: WHI-OS was conducted in 40 U.S. clinical centers. PARTICIPANTS: Women aged 65 to 79, not frail at baseline. MEASUREMENTS: Antidepressant use was assessed through medication container inspection at baseline. Four groups were created according to baseline use and Burnam depression screen (range 0-1, 0.06 cutoff): antidepressant nonusers without depressive symptoms (reference group), antidepressant nonusers with depressive symptoms, antidepressant users without depressive symptoms, and antidepressant users with depressive symptoms. Frailty components included slowness or weakness, exhaustion, low physical activity, and unintended weight loss, ascertained through self-report and physical measurements at baseline and Year 3. RESULTS: Of 27,652 women at baseline, 1,350 (4.9%) were antidepressant users and 1,794 (6.5%) were categorized as depressed. At Year 3, 4,125 (14.9%) were frail. All groups had a greater risk of incident frailty than the reference group. Odds ratios (ORs) ranged from 1.73 (95% confidence interval (CI) = 1.41-2.12) in antidepressant users who were not depressed to 3.63 in antidepressant users who were depressed (95% CI = 2.37-5.55). All durations of use were associated with incident frailty (<1 year OR = 1.95, 95% CI = 1.41-2.68; 1-3 years OR = 1.99, 95% CI = 1.45-2.74; >3 years OR = 1.60, 95% CI = 1.20-2.14). CONCLUSION: In older adult women, depressive symptoms and antidepressant use were associated with frailty after 3 years of follow-up.

Association of secondhand smoke exposure with nicotine dependence among Black smokers.

INTRODUCTION: Exposure to secondhand smoke (SHS) is influenced by norms and regulations, socioeconomic status and immediate personal interactions. SHS exposure may occur in various settings, including the living space, workplace, and other social environments. This study examines the association between exposure to SHS and nicotine dependence among current smokers. METHODS: A cross-sectional sample of 246 Black (60% male and 40% female) current smokers age 40 and older, from Baltimore, Maryland and Washington, D.C, responded to an interviewer-administered questionnaire. We examined nicotine dependence using clinical guidelines based on the Diagnostic and Statistical Manual of Mental Disorders, Text Revision (2000). We performed multivariate logistic regression to assess the association between SHS and nicotine dependence. RESULTS: SHS exposure in the current home environment and exposure in settings outside the home, as well as difficulty to quit smoking and heaviness of smoking, were associated with nicotine dependence. After adjustment for age, gender, education, income, employment status, current alcohol consumption, history of marijuana use, and number of cigarettes smoked per day; exposure to SHS at home only, and in both current home environment and other settings, continued to be associated with clinically-defined nicotine dependence (OR=2.25; 95% CI 1.05, 4.86 vs. OR=2.31; 95% CI 1.03, 5.18), respectively. DISCUSSION: These findings highlight the relative importance of examining SHS exposure in personal (residential and automobile) and public (workplace and outdoor) settings by current smokers. Promotion of smoke-free environments may reduce the prevalence of nicotine dependence among current smokers.

Association between lifestyle factors and CpG island methylation in a cancer-free population.

BACKGROUND: Many risk factors have been associated with cancer, such as age, family history, race, smoking, high-fat diet, and poor nutrition. It is important to reveal the molecular changes related to risk factors that could facilitate early detection, prevention, and overall control of cancer. METHODS: We selected six cancer-specific methylated genes that have previously been reported in primary tumors and have also been detected in different bodily fluids of cancer patients. Here, we used quantitative fluorogenic real-time methylation-specific PCR in plasma DNA samples for the detection of methylation changes from an asymptomatic population who do not have any known cancer. RESULTS: The promoter methylation frequencies of the studied genes were as follows: APC (7%), CCND2 (22%), GSTP1 (2%), MGMT (9%), RARbeta2 (29%), and P16 (3%). Promoter methylation of at least one of the genes analyzed was observed in approximately 46% (72 of 157) of the samples by binary dichotomization. Promoter hypermethylation of at least two genes was detected in 17% (26 of 157) of the samples. RARbeta2 methylation was observed in 45% of subjects who had a high-fat diet in contrast with those who had a low-fat diet (23%; P = 0.007). DISCUSSION: Our findings may help to elucidate early methylation changes that may lead to cancer development. These methylation changes could be due to exposure to risk factors and may be useful for cancer prevention measures such as changes in lifestyle. Longitudinal follow-up of a high-risk population is needed to understand the association of methylation of candidate genes in cancer development.

Clinical course of alcohol dependence in African Americans.

OBJECTIVE: The sequence and progression of alcohol related life events were investigated in a sample of African Americans and compared with findings from a predominantly Caucasian sample. METHODS: Alcohol dependent participants were recruited from treatment facilities. Participants completed the Semi-Structured Assessment for the Genetics of Alcoholism to assess the physical, psychological and social manifestations of alcoholism and related disorders. RESULTS: The sequence and mean age of appearance of alcohol-related life events were similar for this sample of African-American men and women. While there were similarities in the progression of alcohol related life problems between the African American and the Caucasian samples, the frequency of symptom endorsement for most problems was significantly higher in the Caucasian sample. CONCLUSIONS: Identifying ethnic differences in the clinical course of alcohol dependence may be of importance in developing treatment plans and assist in the development of culturally sensitive intervention and prevention programs.

Are depressive symptoms associated with cancer screening and cancer stage at diagnosis among postmenopausal women? The Women's Health Initiative observational cohort.

BACKGROUND: Women with depressive symptoms may use preventive services less frequently and experience poorer health outcomes. We investigated the association of depressive symptoms with breast and colorectal cancer screening rates and stage of cancer among a cohort of postmenopausal women. METHODS: In The Women's Health Initiative Observational Study, 93,676 women were followed on average for 7.6 years. Depressive symptoms were measured at baseline and at 3 years using the 6-item scale from the Center for Epidemiological Studies Depression scale (CES-D). We calculated a cancer screening rate expressed as a proportion of the years that women were current with recommended cancer screening over the number of follow-up visits in the study. Breast and colorectal cancers were staged based on Surveillance, Epidemiology and End Results (SEER) classification. RESULTS: At baseline, 15.8% (12,621) women were positive for depressive symptoms, and 6.9% (4,777) were positive at both baseline screening and at 3 years. The overall average screening rate was 71% for breast cancer and 53% for colorectal cancer. The breast cancer screening rate was 1.5% (CI 0.9%-2.0%) lower among women who reported depressive symptoms at baseline than among those who did not. Depressive symptoms were not a predictor for colorectal cancer screening. Stage of breast and colorectal cancer was not found to be associated with depressive symptoms after adjusting for covariates. CONCLUSIONS: Among a healthy and self-motivated cohort of women, self-reported depressive symptoms were associated with lower rates of screening mammography but not with colorectal cancer screening.

Racial discrimination and breast cancer incidence in US Black women: the Black Women's Health Study.

Perceived discrimination may contribute to somatic disease. The association between perceived discrimination and breast cancer incidence was assessed in the Black Women's Health Study. In 1997, participants completed questions on perceived discrimination in two domains: "everyday" discrimination (e.g., being treated as dishonest) and major experiences of unfair treatment due to race (job, housing, and police). Cox proportional hazards models were used to estimate incidence rate ratios, controlling for breast cancer risk factors. From 1997 to 2003, 593 incident cases of breast cancer were ascertained. In the total sample, there were weak positive associations between cancer incidence and everyday and major discrimination. These associations were stronger among the younger women. Among women aged less than 50 years, those who reported frequent everyday discrimination were at higher risk than were women who reported infrequent experiences. In addition, the incidence rate ratio was 1.32 (95% confidence interval: 1.03, 1.70) for those who reported discrimination on the job and 1.48 (95% confidence interval: 1.01, 2.16) for those who reported discrimination in all three situations - housing, job, and police - relative to those who reported none. These findings suggest that perceived experiences of racism are associated with increased incidence of breast cancer among US Black women, particularly younger women.
