ABSTRACT: Background
Since behavioral factors are significant determinants of population health, addressing prostate cancer (CaP)-related health beliefs and cultural beliefs are key weapons to fight this deadly disease. This study investigated the health beliefs and cultural beliefs of black men relative to CaP, and the key socio-demographic correlates of these beliefs.Methods
The study design was a cross-sectional survey of 2,864 Florida black men, age 40 to 70, on their perceived susceptibility, perceived severity, attitude, outcomes beliefs, perceived behavioral control, CaP fatalism, religiosity, temporal orientation, and acculturation relative to CaP screening and prevention.Results
The men reported favorable attitude and positive outcome beliefs, but moderate perceived behavioral control, CaP susceptibility and CaP severity. They also had low level of acculturation, did not hold fatalistic beliefs about CaP, had high religious coping skills and had high future time perspective. Several demographic variables were found to be associated with health beliefs and cultural beliefs.Discussion
Our study provides rich data with regard to the health and cultural beliefs that might serve to inform the development of CaP control initiative for US-born and foreign-born black men.

Project description:BackgroundHealth disparities in prostate cancer (PC) are thought to reflect the complex interplay of socioeconomics, environment and biology. The potential impact of beliefs and perceptions about PC among Black and Latino populations on clinical disparities are not well understood. This qualitative study was conducted to assess current prevalent and pervasive stigma, beliefs and perceptions regarding PC among Blacks and Latinos living in a large metropolitan area, thereby identifying potentially modifiable barriers to care.MethodsQualitative data were collected through four separate focus groups of self-identified Black and Latino adult men and women living in Philadelphia to better understand their perceptions of PC diagnosis, screening and treatment. Each focus group was single-sex and conducted by racial/ethnic group in order to assess possible differences in beliefs about PC based on gender and racial/ethnic affiliation. Audio recordings were transcribed verbatim by trained research assistants and qualitative data analysis was conducted using modified grounded theory.ResultsThere were a total of 34 participants: 19 Hispanics/Latinos and 15 Blacks, with equal numbers of men and women (n=17). Median age was 57 years (range: 18 to 85 years). Dominant themes that emerged with respect to PC diagnosis included the stigma surrounding this condition and the perceived role of an "unhealthy lifestyle" and certain sexual behaviors as risk factors for PC development. While the majority of participants acknowledged the importance of PC screening and early detection, discussion centered around the barriers to both the interest in seeking medical care and the likelihood of securing it. These barriers included misunderstanding of PC etiology, distrust of the medical profession, and financial/access limitations. Men expressed substantial confusion about PC screening guidelines. In the Black female group, the role of faith and religion in the course of disease was a major theme. Both Black and Latina females discussed the role of fear and avoidance around PC screening and treatment, as well as the prevalence of misinformation about PC in their familial and social communities.ConclusionBlack and Latino focus groups revealed the existence of cultural beliefs, misunderstandings and fears pertaining to PC which could influence health-related behaviors. Some themes were common across groups; others suggested racial and gender predilections. Future targeted efforts focused on directly addressing prevalent misperceptions among underserved communities in urban settings could help to improve health literacy and equity in PC outcomes in these populations.

Project description:PurposeThe Prostate Health Index is validated for prostate cancer detection but has not been well validated for Gleason grade group 2-5 prostate cancer detection in Black men. We hypothesize that the Prostate Health Index has greater accuracy than prostate specific antigen for detection of Gleason grade group 2-5 prostate cancer. We estimated probability of overall and Gleason grade group 2-5 prostate cancer across previously established Prostate Health Index ranges and identified Prostate Health Index cutoffs that maximize specificity for Gleason grade group 2-5 prostate cancer with sensitivity >90%.Materials and methodsWe recruited a "cancer-free" Black control cohort (135 patients) and a cohort of biopsy naïve Black men (158) biopsied for elevated prostate specific antigen. Descriptive statistics compared the prostate cancer cases and controls and the frequency of Gleason grade group 2-5 prostate cancer across Prostate Health Index scores. Receiver operating characteristics compared the discrimination of prostate specific antigen, Prostate Health Index and other prostate specific antigen related biomarkers. Sensitivity and specificity for Gleason grade group 2-5 prostate cancer detection were assessed at prostate specific antigen and Prostate Health Index thresholds alone and in series.ResultsOf biopsied subjects 32.9% had Gleason grade group 2-5 prostate cancer. In Blacks with prostate specific antigen from 4.0-10.0 ng/ml, Prostate Health Index and prostate specific antigen had similar discrimination for Gleason grade group 2-5 prostate cancer (0.63 vs 0.57, p=0.27). In Blacks with prostate specific antigen ≤10.0, a threshold of prostate specific antigen ≥4.0 had 90.4% sensitivity for Gleason grade group 2-5 prostate cancer; a threshold of prostate specific antigen ≥4.0 with Prostate Health Index ≥35.0 in series avoided unnecessary biopsy in 33.0% of men but missed 17.3% of Gleason grade group 2-5 prostate cancer. Prostate specific antigen ≥4.0 with Prostate Health Index ≥28.0 in series spared biopsy in 17.9%, while maintaining 90.4% sensitivity of Gleason grade group 2-5 prostate cancer.ConclusionsThe Prostate Health Index has moderate accuracy in detecting Gleason grade group 2-5 prostate cancer in Blacks, but Prostate Health Index ≥28.0 can be safely used to avoid some unnecessary biopsies in Blacks.

Project description:BackgroundThere are few prospective studies comparing race-specific associations between diet, nutrients, and health-related parameters, and prostate cancer risk.MethodsRace-specific prostate cancer risk associations were examined among men in the National Institutes of Health (NIH)-AARP Diet and Health Study. We identified 1417 cases among black men (209 advanced), and 28,845 among white men (3898 advanced). Cox proportional hazards regression models estimated hazard ratios (HRs) and 95% confidence intervals (CIs). We also evaluated the cumulative change in the HR for black race following adjustment for each factor.ResultsRace-specific prostate cancer associations were similar in black and white men across disease subtypes only for history of diabetes (overall : HR = 0.77, 95% CI: 0.65-0.90 and HR = 0.72, 95% CI: 0.69-0.76, respectively; Pinteraction = 0.66). By contrast, there was a positive risk association with height for white men and inverse for black men (Pinteraction: non-advanced = 0.01; advanced = 0.04). This difference remained among men with at least 2 years of follow-up for non-advanced (Pinteraction = 0.01), but not advanced disease (Pinteraction = 0.24); or after adjustment for prostate cancer screening (non-advanced Pinteraction = 0.53, advanced Pinteraction = 0.31). The only other evidence of interaction with race was observed for dietary vitamin D intake and non-advanced disease, but only after adjustment for screening (Pinteraction = 0.02). Cumulative adjustment for each factor increased the HR for black race by 32.9% for overall cancer and 12.4% for advanced disease.ConclusionsOur data suggest few of the dietary, nutrient, and health-related factors associated with prostate cancer risk in predominantly non-Hispanic white men were associated with risk in black men, and adjustment for these factors widen the black-white difference in risk. Larger studies of black men, particularly with prospective data, are needed to help identify risk factors relevant to this population.

Project description:BACKGROUND:Prostate-specific antigen (PSA) measurement in midlife predicts long-term prostate cancer (PCa) mortality among white men. OBJECTIVE:To determine whether baseline PSA level during midlife predicts risk of aggressive PCa in black men. DESIGN, SETTING, AND PARTICIPANTS:Nested case-control study among black men in the Southern Community Cohort Study recruited between 2002 and 2009. A prospective cohort in the southeastern USA with recruitment from community health centers. A total of 197 incident PCa patients aged 40-64 yr at study entry and 569 controls matched on age, date of blood draw, and site of enrollment. Total PSA was measured in blood collected and stored at enrollment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS:Total and aggressive PCa (91 aggressive: Gleason ?7, American Joint Committee on Cancer stage III/IV, or PCa-specific death). Exact conditional logistic regression estimated odds ratios (ORs) with 95% confidence intervals (CIs) for PCa by category of baseline PSA. RESULTS AND LIMITATIONS:Median PSA among controls was 0.72, 0.80, 0.94, and 1.03ng/ml for age groups 40-49, 50-54, 55-59, and 60-64 yr, respectively; 90th percentile levels were 1.68, 1.85, 2.73, and 3.33ng/ml. Furthermore, 95% of total and 97% of aggressive cases had baseline PSA above the age-specific median. Median follow-up was 9 yr. The OR for total PCa comparing PSA >90th percentile versus ?median was 83.6 (95% CI, 21.2-539) for 40-54 yr and 71.7 (95% CI, 23.3-288) for 55-64 yr. For aggressive cancer, ORs were 174 (95% CI, 32.3-infinity) for 40-54 yr and 51.8 (95% CI, 11.0-519) for 55-64 yr. A composite endpoint of aggressive PCa based on stage, grade, and mortality was used and is a limitation. CONCLUSIONS:PSA levels in midlife strongly predicted total and aggressive PCa among black men. PSA levels among controls were similar to those among white controls in prior studies. PATIENT SUMMARY:Prostate-specific antigen (PSA) level during midlife strongly predicted future development of aggressive prostate cancer among black men. Targeted screening based on a midlife PSA might identify men at high risk while minimizing screening in those men at low risk.

Project description:BackgroundModification is an important process by which to adapt an instrument to be used for another culture. However, it is not fully understood how best to modify an instrument to be used appropriately in another culture.ObjectiveThis study aims to synthesize the modification strategies used in the cross-cultural adaptation process for instruments measuring health beliefs about cancer screening.MethodsA systematic review design was used for conducting this study. Keywords including constructs about instrument modification, health belief, and cancer screening were searched in the PubMed, Google Scholar, CINAHL, and PsycINFO databases. Bowling's checklist was used to evaluate methodological rigor of the included articles. Results were reported using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) approach with a narrative method.ResultsA total of 1312 articles were initially identified in the databases. After removing duplications and assessing titles, abstracts, and texts of the articles, 18 studies met the inclusion criteria for the study. Based on Flaherty's cultural equivalence model, strategies used in the modification process included rephrasing items and response options to achieve semantic equivalence; changing subjects of items, changing wording of items, adding items, and deleting items to achieve content equivalence; adding subscales and items and deleting subscales and items to achieve criterion equivalence. Solutions used to resolve disagreements in the modification process included consultation with experts or literature search, following the majority, and consultation with the author who developed the scales.ConclusionsThis study provides guidance for researchers who want to modify an instrument to be used in another culture. It can potentially give cross-cultural researchers insight into modification strategies and a better understanding of the modification process in cross-cultural instrument adaptation. More research could be done to help researchers better modify cross-cultural instruments to achieve cultural equivalence.

Project description:Conventional definitions of mental health, manhood, and social support create barriers to accessing behavioral health care for Black men ages 18 to 30. Targeted behavioral health interventions sensitive to culture, social norms, and gender that circumvent these barriers are desperately needed to improve access and integrated care for this group. This article reports mixed methods findings from the 2017 iteration of the Young Black Men, Masculinities, and Mental Health (YBMen) project, a social media-based, psychoeducational program that promotes mental health, progressive definitions of manhood, and sustainable social support for Black men. Young Black men (n = 350) across two universities in the Midwest completed baseline surveys on their mental health, definitions of manhood, and social support. Forty of the men participated in the YBMen intervention and at postintervention reported experiencing fewer depressive symptoms on the Patient Health Questionnaire (PHQ-9, Z = -2.05, p < .01) and the Gotland Male Depression Scale (GMDS; Z = -1.76, p < .05). There were also changes on the Conformity to Masculine Norms Inventory (CMNI) for Self-Reliance (Z = -0.34, p = .26) and Heterosexual Self-Presentation (Z = -0.18, p = .59), though these changes were not statistically significant. A qualitative review of postintervention interviews revealed participants' appreciation of the YBMen project and its influence on their mental health, manhood, and social support. Programmatic efforts that support the behavioral health, positive development, and social relationships of Black men translate into positive families, communities, and experiences as they live, learn, love, and work over the life course.

Project description:We have demonstrated that the miR-182 level, in addition to being significantly increased in colon cancer compared to adjacent normal colon tissue, is also significantly increased in African American(AA) compared to Caucasian American (CA) colon cancer. Since miR-182 has been previously associated with decreased survival in colon cancer patients and with increased liver metastases, this observation supports the concept that biological differences between AA and CA colon cancers may contribute to AA disparities in colon cancer survival. We aimed to identify miRNAs that were associated with effects of both tumor and race by generating Agilent miRNA expression profiles on paired colon cancer and adjacent normal colon collected from AA and CA colon cancer subjects. For the 30 paired Stony Brook University (SBU) colon cancer and adjacent normal colon samples, attempts were made to control for other covariates such as age, colon cancer location, stage, BMI and smoking in the selection of the CA samples . However no attempt was made to control for the other covariates in the 30 paired Washington University (WU) colon cancer and adjacent normal colon samples.

Project description:BackgroundBlack men have worse prostate cancer outcomes following treatment than White men even when accounting for prognostic factors. However, biological explanations for this racial disparity have not been fully identified. We previously showed that more variable telomere lengths among cancer cells and shorter telomere lengths in cancer-associated stromal (CAS) cells individually and together ("telomere biomarker") are associated with prostate cancer-related death in surgically treated men independent of currently used prognostic indicators. Here, we hypothesize that Black-White differences in the telomere biomarker and/or in its components may help explain the racial disparity in prostate cancer outcomes.MethodsBlack [higher grade (Gleason ≥4+3) = 34 and lower grade = 93] and White (higher grade = 34 and lower grade = 89) surgically treated men were frequency matched on age, pathologic stage, and grade. We measured telomere lengths in cancer and CAS cells using a robust telomere-specific FISH assay. Tissue microarray and grade-specific distributional cutoff points without regard to race were evaluated.ResultsAmong men with higher grade disease, the proportion of Black men (47.1%) with more variable cancer cell telomere lengths was 2.3-times higher (P = 0.02) than that in White men (20.6%). In contrast, among men with lower grade disease, cancer cell telomere length variability did not differ by race. The proportion of men with shorter CAS cell telomeres did not differ by race for either higher or lower grade disease.ConclusionsA greater proportion of Black men with higher grade disease have an adverse prostate cancer cell telomere phenotype than White men with higher grade disease.ImpactOur findings suggest a possible explanation for the racial disparity in prostate cancer outcomes.

Project description:BackgroundThis study examined factors influencing cultural beliefs associated with later-stage detection of breast cancer and determined what factors influence those cultural beliefs in Vietnamese women residing in a rural Vietnamese community.MethodsA cross-sectional survey was conducted with 289 women aged 20-64 years from 12 villages using a self-administered structured questionnaire. Cultural beliefs were measured with a 13-item cultural beliefs scale consisting of four domains-characteristics of breast lumps, self-help techniques, faith-based beliefs, and futility of treatment. Data were collected in February 2017 and analyzed using chi-square tests, nonparametric tests, Fisher's exact tests, and multiple linear regression analyses with SPSS/WIN 24.0 statistical software.ResultsAlthough the total score was relatively low (3.4 out of 13), cultural beliefs that could contribute to later-stage breast cancer were identified. Younger women (β = .15, p = .016) and women with a lower income (β = .21, p < .001) held more erroneous cultural beliefs as compared to their counterparts. Most women believed they would not get breast cancer if they took care of themselves. More than one-third held cultural beliefs about breast lumps, thinking they would need to be painful and/or actively growing to be breast cancer.ConclusionsThe results support the urgent need for education concerning breast cancer health promotion, including breast cancer assessment as well as guidance on evidence-based and up-to-date detection measures to change rural Vietnamese women's cultural beliefs.

Project description:Epidemiological studies show that the incidence and mortality rates of prostate cancer (PCa) are significantly higher in African-American (AA) men when compared with Caucasian (CA) men in the United States. Transforming growth factor ? (TGF?) signaling pathway is linked to health disparities in AAs. Recent studies suggest a role of TGF?3 in cancer metastases and its effect on the migratory and invasive behavior; however, its role in PCa in AA men has not been studied. We determined the circulating levels of TGF?3 in AA and CA men diagnosed with PCa using ELISA. We analyzed serum samples from both AA and CA men diagnosed with and without PCa. We show that AA PCa patients had higher levels of TGF?3 protein compared with AA controls and CA patients. In fact, TGF?3 protein levels in serum were higher in AA men without PCa compared with the CA population, which may correlate with more aggressive disease seen in AA men. Studies on AA-derived PCa cell lines revealed that TGF?3 protein levels were also higher in these cells compared with CA-derived PCa cell lines. Our studies also reveal that TGF? does not inhibit cell proliferation in AA-derived PCa cell lines, but it does induce migration and invasion through activation of PI3K pathway. We suggest that increased TGF?3 levels are responsible for development of aggressive PCa in AA patients as a consequence of development of resistance to inhibitory effects of TGF? on cell proliferation and induction of invasive metastatic behavior.
