Religious Coping and Quality of Life Among Black and White Men With Prostate Cancer.

Prostate cancer is a significant impediment in men's lives as this condition often exacerbates stress and reduces quality of life. Faith can be a resource through which men cope with health crises; however, few studies examine how religion or spirituality can have implications for racial disparities in health outcomes among men. The purpose of this study is to assess the associations between religious coping and quality of life among black and white men with prostate cancer. Data for this investigation were drawn from the Diagnosis and Decisions in Prostate Cancer Treatment Outcomes Study that consisted of 624 black and white men with complete information on the primary outcome and predictor variables. The primary outcome for this study was overall quality of life as measured by the Functional Assessment of Cancer Therapy-Prostate questionnaire. The main independent variable was religious coping measured by 2 subscales capturing positive and negative forms of coping. Black men in the study had lower overall quality of life scores (134.6 ± 19.6) than their white peers (139.8 ± 14.1). Black men in the sample also had higher average positive religious coping scores (12.9 ± 3.3) than white men (10.3 ± 4.5). Fully adjusted linear regression models of the total sample produced results indicating that positive religious coping was correlated with an increase in quality of life (ß = .38, standard error [SE] = 0.18, P < .05). Negative religious coping was associated with a reduction in quality of life (ß = -1.48, SE = 0.40, P < .001). Faith-oriented beliefs or perceptions can have implications for quality of life among men with prostate cancer. Sensitivity to the role of religion, spirituality, and faith should be seen by providers of health care as potential opportunities for improved outcomes in patients with prostate cancer and survivors.

Black Pastors' Views on preaching about sex: barriers, facilitators, and opportunities for HIV prevention messaging.

OBJECTIVES: Despite the disproportionately high rates of heterosexually transmitted HIV infection among US Blacks and ongoing need for effective inexpensive behavioral interventions, the use of sermons as an HIV prevention tool in Black churches has received little research attention. The Black church plays an important role in Black communities and is a potential ally in development and delivery of sexual risk prevention messages. The objective of this study was to examine Black pastors' thoughts about whether sermons should address issues related to heterosexual relationships - and the barriers and facilitators to discussing these topics in a sermon setting. DESIGN: We conducted in-depth semi-structured, individual interviews among 39 pastors of Black churches in North Carolina and analyzed the interview data using thematic analysis strategies based on grounded theory. RESULTS: Pastors expressed widely ranging opinions, especially about discussion of condom use, but generally agreed that sermons should discuss marriage, abstinence, monogamy, dating, and infidelity - behaviors that impact sexual networks and HIV transmission. The major barriers to incorporation of these subjects into sermons include the extent to which a concept undermines their religious beliefs and uncertainty about how to incorporate it. However, scriptural support for a prevention message and the pastor's perception that the message is relevant to the congregation facilitate incorporation of related topics into sermons. CONCLUSIONS: These findings have implications for the potential utility of sermons as an HIV prevention tool and suggest that it is possible for public health professionals and pastors of Black churches to form partnerships to develop messages that are consonant with pastors' religious convictions as well as public health recommendations.

Primary Care Physicians Beliefs about Prostate-Specific Antigen Evidence Uncertainty, Screening Efficacy, and Test Use.

BACKGROUND/PURPOSE: Little is known about primary care physicians' (PCPs) beliefs about prostate cancer screening efficacy, evidence uncertainty, and their actual screening behaviors. We examined factors associated with PCP beliefs about screening efficacy and uncertainty and whether beliefs were associated with prostate specific-antigen (PSA) test use. METHODS: The 2008 National Survey of Primary Care Physicians' Practices Regarding Prostate Cancer Screening collected information on physicians' attitudes, beliefs, and practices related to prostate cancer and screening (n=1,256). Two factors were constructed that measured belief in certainty of evidence for PSA testing and belief in screening efficacy. These factors, along with PCP sociodemographic and practice-related factors, were used to examine associations with offering the PSA test. RESULTS: Most PCPs were male (70%), Caucasian (76%), under age 50 (56%), and practiced in communities with more than 50,000 residents (54%). In bivariate analysis, variables associated with PCP belief in evidence uncertainty included female gender, younger age, and lower patient volume. Variables associated with belief in screening efficacy included older age and general and family practice specialty. After adjustment, PCPs with high belief in evidence uncertainty were less likely (OR=0.19, 95% CI=0.06, 0.62) to offer PSA and more likely to practice shared decision making (OR=1.80, 95% CI=1.22-2.67). PCPs with high belief in screening efficacy were more likely (OR=2.99, 95% CI=1.15, 7.77) to offer PSA and less likely to practice shared decision making (OR=0.47, 95% CI=0.32-0.70). CONCLUSION: Our data indicate that belief patterns about evidence uncertainty and the efficacy of using PSA may play a role in whether PCPs offer PSA.

High Levels of Medical Mistrust Are Associated With Low Quality of Life Among Black and White Men With Prostate Cancer.

BACKGROUND: Medical mistrust is thought to affect health care-based decisions and has been linked to poor health outcomes. The effects of medical mistrust among men with prostate cancer are unknown. Thus, the goal of the current study is to examine the association between medical mistrust and quality of life (QOL) among black and white men with prostate cancer. METHODS: A total of 877 men (415 black, 462 white) with prostate cancer between the ages of 40 to 81 years who entered the North Carolina Central Cancer Registry during the years 2007 and 2008 were retrospectively recruited. The dependent variable was overall QOL measured by the Functional Assessment of Cancer Therapy-Prostate questionnaire. The primary independent variable was medical mistrust. Multivariate regression analysis was used to assess the association between medical mistrust and overall QOL. RESULTS: Compared with white men, black men reported a higher level of medical mistrust (black = 2.7, white = 2.4; P < .001) and lower QOL (black = 134.4, white = 139.5; P < 0.001). After controlling for demographical and clinical variables, higher levels of medical mistrust were associated with a reduction in overall QOL among men with prostate cancer (beta = -7.73; standard error = 1.54) CONCLUSIONS: Higher levels of medical mistrust are associated with reduced overall QOL among black and white men with prostate cancer. Interventions targeted to reduce medical mistrust may be effective in increasing the overall QOL of men with prostate cancer.

Prevalence and Correlates of Major Depressive Symptoms among Black Men with Prostate Cancer.

Objectives: The objectives of our study were to determine the prevalence of major depressive symptoms and identify factors that are associated with major depressive symptoms among Black men with prostate cancer (PCa). Design: This study consisted of 415 Black men aged 40-81 years that entered the North Carolina Central Cancer Registry during the years 2007-2008. The primary outcome variable was depressive symptoms (CES-D). Factors included age, income, education, insurance status, treatment received, time between diagnosis and treatment, Gleason score, medical mistrust and experience with racism/discrimination. Logistic regression models were used to assess factors associated with the odds of having major depressive symptoms. Results: The prevalence of major depressive symptoms (≥16 on CES-D) among our sample of Black men with PCa was approximately 33%. Approximately 15% of the study participants underwent radiation beam treatment. Age was significantly associated with the odds of reporting major depressive symptoms (OR= .95, CI .91-.99) among Black men. In addition, compared with all other forms of treatment, Black men who underwent radiation beam treatment had higher odds (OR=2.38, CI 1.02- 5.51) of reporting major depressive symptoms. Conclusion: Nearly one-third of Black men with PCa in this study reported major depressive symptoms. Clinicians should pay closer attention to the mental health status of Black men with PCa, especially those who are younger and those who have undergone radiation beam treatment. Cancer survivorship, particularly quality of life, may be enhanced by opportunities for assessment, evaluation and intervention of depressive symptoms among these men disproportionately affected by PCa.

Racial Disparity in Time Between First Diagnosis and Initial Treatment of Prostate Cancer.

BACKGROUND: Disparities among patients with prostate cancer exist across the continuum of care. The interval of time that lapses between first diagnosis and treatment is another disparity that may exist but has not been fully explored. METHODS: Our study looked at the data of 749 men (353 black and 396 white) who were 40 to 81 years of age when they entered the North Carolina Central Cancer Registry during the years 2007 and 2008. Our dependent variable was the amount of months that had passed between first diagnosis and treatment. Our main independent variable was self-reported race. Covariates included age, income, level of education, insurance status, treatment received, Gleason score, and level of medical mistrust. We used negative binomial regression analysis to determine the association between the amount of time that lapsed between a diagnosis of prostate cancer and treatment by race. RESULTS: Compared with white men, black men were more likely to experience a longer wait time between diagnosis and treatment of prostate cancer (incidence rate ratio [IRR] 1.19; 95% confidence interval [CI], 1.04-1.36). Controls for demographical, clinical, and psychosocial variables (IRR 1.24; 95% CI, 1.04-1.43) did not explain this difference between the races. CONCLUSIONS: These results suggest that the amount of time that lapses between first diagnosis and treatment of prostate cancer is longer for black men compared with white men. Our findings have identified an underreported racial disparity in the disease continuum of prostate cancer.

Factors Associated with Men's Assessment of Prostate Cancer Treatment Choice.

The objective of this study is to examine factors among a group of African American and White men in North Carolina and their assessment of prostate cancer treatment choice or belief that treatment chosen was best. A sample of men (N = 877) with a history of prostate cancer diagnosis was recruited from the North Carolina Cancer Registry during 2007-2008 and asked to participate in a telephone interview covering several measures about their initial prostate cancer treatment. Logistic regression was used to assess demographic, psychosocial, and clinical factors on whether they felt that they had chosen the best treatment for the disease. Respondents were majority White (52.7 %), married (75.9 %), and had surgery (67.9 %) as their initial treatment. At the bivariate level, factors associated with the belief that the treatment chosen was best were as follows: White race/ethnicity, higher levels of education, a more recent treatment date, having health insurance coverage, type of treatment received, higher levels of bother from side effects, greater contentment with their quality of life, and doctor discussions of the various treatment options. Similarly, the multivariate analysis showed increased odds of belief that the treatment chosen was the best among demographic (i.e., race/ethnicity, level of education, and health insurance coverage) as well as psychosocial and clinical variables (i.e., greater bother from side effects, greater contentment with their quality of life, and initial treatment received). Results suggest that demographic, psychosocial, and clinical factors play an important role for men in assessing their treatment choices for prostate cancer.

Examining characteristics of congregation members willing to attend health promotion in African American churches.

BACKGROUND: Although churches are an important partner for improving health within the African American community, it is not known how congregants are best reached by health promotion activities and thus how best to target members in recruitment. This study examined how characteristics of churches and congregants' beliefs and interests in faith-based health promotion related to their willingness to attend church-based health promotion activities. METHOD: We surveyed adult congregants (n = 1,204) of 11 predominately African American churches in North Carolina. Surveys collected data within four domains: demographics (age, sex, education), behavioral (church attendance, respondent food choices, and physical activity), cognitive (church-based health promotion belief, Bible-based healthy living interest, healthy living resource interest), or environmental (family health, church travel distance, church health ministry activity, church members' food choices). Analyses used a dichotomous outcome, interest in attending programs offered by the health ministry. Domain-specific models were constructed. Logistic generalized estimating equations adjusted for clustering. RESULTS: Of the 1,204 congregants, 72% were female, 57% were 50 years or older, 84% had a high school education or more, and 77% had a chronic health condition. In bivariate analyses and in models adjusting for all four domains, cognitive factors had the highest odds of willingness to attend. CONCLUSION: Congregants' belief in the church's role in health promotion and their desire to learn about healthy behaviors highlight the role of the African American church as a partner in addressing health disparities and the need to capitalize on this expectation through stronger partnerships between medical and faith communities.

Participating in research: attitudes within the African American church.

We assessed associations between pastor and congregant characteristics and congregant attitudes about research participation among African American churches. Respondents shared their attitudes regarding how willing, ready, and confident they were about research participation. The outcome measure, the index of research preparedness, summed responses across the domains of willingness, readiness, and confidence. Pastor age and pastor educational attainment were independently associated with a congregants' higher index of research preparedness. Young and educated pastors were significantly associated with congregant attitudes about participation preparedness, a finding that highlights the importance of the pastor regarding congregant research participation decisions.

Gunshot victims at a major level I trauma center: a study of 343,866 emergency department visits.

BACKGROUND: Disturbing trends regarding the sex, age, and race of gunshot victims have been reported in previous national studies; however, gunshot trends have not been well documented in individual cities in the southeastern United States. OBJECTIVES: 1) Analyze trends in gunshot wounds, particularly the association between gunshot wounds and race, among victims presenting to a Level I Trauma Center in Middle Tennessee; 2) Compare specific characteristics of gunshot victims to the general Emergency Department (ED) population. METHODS: This is a retrospective cohort study of 343,866 ED visits from 2004 to 2009. RESULTS: Compared to the general ED population, gunshot victims were more predominantly male (87.5% vs. 43.4%), black (57.6% vs. 29.5%), younger (47.8% under age 25 years vs. 31.6%), and demonstrated higher Medicaid enrollment (78.6% vs. 44.7%). The majority of black gunshot victims were aged 18-25 years (47.1%) and victims of assault (65.9%). Non-black gunshot victims suffered more unintentional (40.2% vs. 28.2%) and self-inflicted (9.1% vs. 0.4%) injuries and were more evenly distributed among ages 18-55 years. Black patients were 3.03 (95% confidence interval 2.93-3.14) times more likely to present to this ED for gunshot wounds than non-black patients, after controlling for age, sex, and insurance status (p < 0.001). CONCLUSIONS: Our study demonstrates that black patients between 18 and 25 years of age presenting to this trauma center are more likely to be victims of gun violence than their non-black counterparts. Our study evaluates trends in gun violence in the Southeast, particularly in relation to race, age, and insurance status.

Coping With Disasters and Pandemics Through Experience and Community: How African American Older Adults Navigate Disaster Planning, Response, and Recovery.

OBJECTIVE: Studies have reported that minorities are disproportionately impacted by the COVID-19 pandemic. Few studies have elucidated the lived experiences of African American older adults, and the resiliency displayed in combatting the COVID-19 pandemic and other disasters. METHODS: This study used 4 recorded focus groups with 26 African American older adults who have spent most of their lives living in Houston, Texas to assess safety, economic, and health concerns related to the pandemic and similarities or differences with other types of disasters that are specific to Houston/ the Gulf Region of Texas, such as Hurricane Harvey. RESULTS: Key themes emerged from the thematic analysis: 1) previous disasters provided important coping and preparation skills, although each occurrence was still a major stressor, 2) while telehealth was a significant benefit, regular health maintenance and chronic disease management were not completed during the COVID-19 pandemic, 3) information from the federal and state authorities were inconsistent and spurred fear and anxiety, 4) participants experienced few to no disruptions to their income but were heavily called on to support family members, and 5) participants experienced anxiety and isolation, but many used existing social connections to cope. CONCLUSIONS: These findings demonstrate how African American older adults navigate disaster response and recovery through experience and community. Providing unambiguous information to older adults could prove useful in preparing for future disaster events and coping with disasters.

Predicting and responding to change: Perceived environmental uncertainty among substance use disorder treatment programs.

INTRODUCTION: Substance use disorder (SUD) treatment programs offering addiction health services (AHS) must be prepared to adapt to change in their operating environment. These environmental uncertainties may have implications for service delivery, and ultimately patient outcomes. To adapt to a multitude of environmental uncertainties, treatment programs must be prepared to predict and respond to change. Yet, research on treatment programs preparedness for change is sparse. We examined reported difficulties in predicting and responding to changes in the AHS system, and factors associated with these outcomes. METHODS: Cross-sectional surveys of SUD treatment programs in the United States in 2014 and 2017. We used linear and ordered logistic regression to examine associations between key independent variables (e.g., program, staff, and client characteristics) and four outcomes, (1) reported difficulties in predicting change, (2) predicting effect of change on organization, (3) responding to change, and (4) predicting changes to make to respond to environmental uncertainties. Data were collected through telephone surveys. RESULTS: The proportion of SUD treatment programs reporting difficulty predicting and responding to changes in the AHS system decreased from 2014 to 2017. However, a considerable proportion still reported difficulty in 2017. We identified that different organizational characteristics are associated with their reported ability to predict or respond to environmental uncertainty. Findings show that predicting change is significantly associated with program characteristics only, while predicting effect of change on organizations is associated with program and staff characteristics. Deciding how to respond to change is associated with program, staff, and client characteristics, while predicting changes to make to respond is associated with staff characteristics only. CONCLUSIONS: Although treatment programs reported decreased difficulty predicting and responding to changes, our findings identify program characteristics and attributes that could better position programs with the foresight to more effectively predict and respond to uncertainties. Given resource constraints at multiple levels in treatment programs, this knowledge might help identify and optimize aspects of programs to intervene upon to enhance their adaptability to change. These efforts may positively influences processes or care delivery, and ultimately translate into improvements in patient outcomes.

Workforce Diversity and disparities in wait time and retention among opioid treatment programs.

BACKGROUND: Workforce diversity is a key strategy to improve treatment engagement among members of racial and ethnic minority groups. In this study, we seek to determine whether workforce diversity plays a role in reducing racial and ethnic differences in wait time to treatment entry and retention in different types of opioid use disorder treatment programs. METHODS: We conducted comparative and predictive analysis in a subsample of outpatient opioid treatment programs (OTPs), who completed access and retention survey questions in four waves of the National Drug Abuse Treatment System Survey (162 OTPs in 2000, 173 OTPs in 2005, 282 OTPs in 2014, and 300 OTPs in 2017). We sought to assess the associations between workforce diversity on wait time and retention, accounting for the role of Medicaid expansion and the moderating role of program ownership type (i.e., public, non-profit, for-profit) among OTPs located across the United States. RESULTS: We found significant differences in wait time to treatment entry and retention in treatment across waves. Average number of waiting days decreased in 2014 and 2017; post Medicaid expansion per the Affordable Care Act, while retention rates varied across years. Key findings show that programs with high diversity, measured by higher percent of African American staff and a higher percent of African American clients, were associated with longer wait times to enter treatment, compared to low diversity programs. Programs with higher percent of Latino staff and a higher percent of Latino clients were associated with lower retention in treatment compared with low diversity programs. However, program ownership type (public, non-profit and for-profit) played a moderating role. Public programs with higher percent of African American staff were associated with lower wait time, while non-profit programs with higher percent of Latino staff were related to higher retention. CONCLUSIONS: Findings show decreases in wait time over the years with significant variation in retention during the same period. Concordance in high workforce and client diversity was associated with higher wait time and lower retention. But these relations inverted (low wait time and high retention) in public and non-profit programs with high staff diversity. Findings have implications for building resources and service capacity among OTPs that serve a higher proportion of minority clients.

Trends in prostate-specific antigen test use, 2000-2005.

OBJECTIVE: This study examined prostate-specific antigen (PSA) test use among men and identified sociodemographic and health-related characteristics associated with its use over time. METHODS: The National Health Interview Survey collected information on PSA test use among 16,058 men > or = 40 years of age in 2000 and 2005. We examined two outcomes: (1) having had a recent (within two years) screening PSA test and (2) having had three or more PSA tests in the past five years (to indicate frequent use). RESULTS: Marital status, family history of prostate cancer, and having seen a doctor in the past year differed over time in the unadjusted model. In the adjusted model, recent PSA screening decreased from 2000 to 2005 for single, never-married men, but increased for men with chronic diseases. Frequent PSA test use increased for men with a family history of prostate cancer, men with chronic diseases, and men who had seen a physician in the past year. Significant correlates of higher recent PSA test use included being older, married, and of black race/ethnicity; having higher levels of education and income, health-care coverage, and a usual place of health care; and increased comorbidity. CONCLUSION: Major organizations are not in agreement about the efficacy of prostate cancer screening; however, men > or = 40 years of age continue to use the PSA test. Both recent screening and frequent testing showed variability during the study period and may have implications for the ongoing randomized clinical trials that are expected to clarify whether early detection of prostate cancer with PSA testing increases survival.

Predicting glaucoma diagnosis in an elderly sample: revisiting the established populations for epidemiologic studies of the elderly.

UNLABELLED: Though research has examined race as an important factor in defining the scope of glaucoma in the United States, further exploration into other specific factors may help inform the design of preventive services to decrease rates of blindness due to glaucoma among minority groups. METHODS: This study examined glaucoma diagnosis among a sample of elderly patients from the North Carolina Established Populations for the Epidemiologic Studies of the Elderly. RESULTS: Caucasians without diabetes are more likely to have a glaucoma diagnosis. In contrast, having diabetes was a marginally significant predictor of a glaucoma diagnosis among African American study participants. CONCLUSION: Identifying individual-level characteristics and different service-level issues that underlie specific ethnic groups may help to develop more precisely targeted interventions to improve a full range of health care services for elderly patients.

Assessing the readiness of black churches to engage in health disparities research.

We assessed church readiness to engage in health disparities research using a newly developed instrument, examined the correlates of readiness, and described strategies that churches used to promote health. We pilot tested the instrument with churches in a church-academic partnership (n = 12). We determined level of readiness to engage in research and assessed correlates of readiness. We also conducted interviews with participating pastors to explore strategies they had in place to support research engagement. Churches scored fairly high in readiness (average of 4.04 out of 5). Churches with a pastor who promoted the importance of good nutrition in a sermon or had a budget for health-related activities had significantly higher readiness scores than churches without such practices. Having a tool to evaluate church readiness to engage in research will inform targeted technical assistance and research projects that will strengthen church-academic partnerships and improve capacity to address health disparities.

Correlates of Social Isolation Among Community-Dwelling Older Adults During the COVID-19 Pandemic.

Background: The past year has severely curtailed social interactions among older adults given their high rates of COVID-19 morbidity and mortality. This study examined social, behavioral, and medical correlates of social isolation among community-dwelling older adults during the COVID-19 pandemic and stratified findings to explore unique differences in two typically neglected populations, African American and Hispanic older adults. Methods: Working with community-based organizations and senior living centers, the research team administered a survey to older adults 55 years of age and older (n = 575). The survey assessed COVID-19 prevention behaviors, medical conditions, and lived experiences, including feelings of social isolation, in the target population. Responses to a previously validated social isolation question informed a dichotomous social isolation dependent variable. Multivariable logistic regression was used to adjust for sociodemographic characteristics, medical conditions, unmet caregiving needs, and COVID-19 prevention behaviors. Results from the regression model were stratified by race/ethnicity to examine correlates of social isolation in African American and Hispanic older adults, separately. Results: Overall, female sex and a higher level of education were also positively associated with social isolation (OR = 2.46, p = 0.04; OR = 5.49, p = 0.02) while having insurance exhibited an inverse relationship (OR = 0.25, p = 0.03). Unmet caregiving needs were strongly associated with social isolation (OR = 6.41, p < 0.001) as was having any chronic conditions (OR = 2.99, p = 0.02). Diabetes was the single strongest chronic condition predictor of social isolation. Among minority older adults, a different pattern emerged. For Hispanic older adults, language, unmet caregiving needs, and social distancing were strongly associated with social isolation; while unmet caregiving needs, having 1+ chronic conditions and adhering to social distancing guidelines were significant predictors in African American older adults. Conclusion: These findings suggest that social isolation affects older adults in a myriad of ways and support the need for culturally sensitive initiatives to mitigate the effect of social isolation in these vulnerable populations.

Church Attendance and Mobility Limitation Among Black and White Men With Prostate Cancer.

Prostate cancer is a significant impediment that can reduce physical functional status. Mobility is fundamental for quality of life and church attendance to be associated with improved physical functioning. Few studies have examined how religious participation have implications for mobility limitation among men in general and among prostate cancer survivors in particular. The purpose of this study was to assess the association between church attendance and mobility limitation among Black and White prostate cancer patients and survivors. Data for this investigation were drawn from the Diagnosis and Decisions in Prostate Cancer Treatment Outcomes Study that consisted of 804 Black and White men with complete information on the primary outcome and predictor variables. Mobility limitation was the primary outcome variable, and church attendance was the main independent variable. The analytic sample was almost equally divided between Black (N = 382) and White men (N = 422). The proportion of Black men reporting mobility limitation (30.09%) more than doubled the corresponding percentage for White men (14.7%). Black men had a higher proportion of individuals who reported weekly church attendance (49.2% vs. 45.0%). Fully adjusted modified Poisson regression models produced results indicating that respondents attending church weekly had a lower mobility limitation prevalence (PR = 0.56, 95% CI [0.39, 0.81]) than those never attending church. Results from this study contribute to the body of evidence asserting the health benefits of church attendance. These findings suggest that health providers should consider how religion and spirituality can present opportunities for improved outcomes in prostate cancer patients and survivors.

Racial differences in PSA screening interval and stage at diagnosis.

OBJECTIVES: This study examined PSA screening interval of black and white men aged 65 or older and its association with prostate cancer stage at diagnosis. METHODS: SEER-Medicare data were examined for 18,067 black and white men diagnosed with prostate cancer between 1994 and 2002. Logistic regression was used to assess the association between race, PSA screening interval, and stage at diagnosis. Analysis also controlled for age, marital status, comorbidity, diagnosis year, geographic region, income, and receipt of surgery. RESULTS: Compared to whites, blacks diagnosed with prostate cancer were more likely to have had a longer PSA screening interval prior to diagnosis, including a greater likelihood of no pre-diagnosis use of PSA screening. Controlling for PSA screening interval was associated with a reduction in blacks' relative odds of being diagnosed with advanced (stage III or IV) prostate cancer, to a point that the stage at diagnosis was not statistically different from that of whites (OR=1.12, 95% CI=0.98-1.29). Longer intra-PSA intervals were systematically associated with greater odds of diagnosis with advanced disease. CONCLUSIONS: More frequent or systematic PSA screening may be a pathway to reducing racial differences in prostate cancer stage at diagnosis, and, by extension, mortality.

Weight change and functional limitations among older adults in North Carolina.

There is emerging evidence that weight change during older adulthood is associated with decreased physical function; however, less is known about the association between weight change during middle to older adulthood and physical function. This study assessed the association of weight change between middle and older adulthood and functional limitations among 2,531 older African-American and white participants, ages 65 and older at baseline (1987), from the Piedmont Health Survey of the Elderly. Weight gainers had ≥8% increase in weight, weight losers had >8% decrease in weight, and weight maintainers had <8% increase or decrease between age 50 and baseline. Functional limitations were categorized as none (0), mild (1-3), or severe (4 or more) using items from the activities of daily living scale by Katz and the extremity function scale by Nagi. Modified Poisson regression was used to assess these associations in crude and adjusted analyses. Weight gain and weight loss between age 50 and baseline were associated with severe functional limitations (prevalence ratio (PR) = 1.19, 95% CI: 1.04, 1.36 and PR = 1.58, 95% CI: 1.41, 1.78, respectively) compared to weight maintainers after adjustment for age, race, and gender. These associations were attenuated after additional adjustment for health characteristics, while weaker associations were noted for mild functional limitations. In summary, weight gain and weight loss between middle and older adulthood were associated with severe functional limitations among older adults in North Carolina. Additional research is needed to explore weight change across the life course and its possible effects on physical function later in life.
