Abstract
OBJECTIVE To assess the dose-dependent relationship between smoking history and cancer screening rates or staging of cancer diagnoses. DESIGN Prospective, population-based cohort study. SETTING Questionnaire responses from the Women's Health Initiative (WHI) Observational Study. PARTICIPANTS 89 058 postmenopausal women. OUTCOME MEASURES Logistic regression models were used to assess the odds of obtaining breast, cervical, and colorectal cancer screening as stratified by smoking status. The odds of late-stage cancer diagnoses among patients with adequate vs inadequate screening as stratified by smoking status were also calculated. RESULTS Of the 89 058 women who participated, 52.8% were never smokers, 40.8% were former smokers, and 6.37% were current smokers. Over an average of 8.8 years of follow-up, current smokers had lower odds of obtaining breast (OR 0.55; 95% CI 0.51 to 0.59), cervical (OR 0.53; 95% CI 0.47 to 0.59), and colorectal cancer (OR 0.71; 95% CI 0.66 to 0.76) screening compared with never smokers. Former smokers were more likely than never smokers to receive regular screening services. Failure to adhere to screening guidelines resulted in diagnoses at higher cancer stages among current smokers for breast cancer (OR 2.78; 95% CI 1.64 to 4.70) and colorectal cancer (OR 2.26; 95% CI 1.01 to 5.05). CONCLUSIONS Active smoking is strongly associated with decreased use of cancer screening services and more advanced cancer stage at the time of diagnosis. Clinicians should emphasise the promotion of both smoking cessation and cancer screening for this high-risk group.

Link between prostate cancer diagnosis and stroke in the United States during 2007-2017. ACTA ACUST UNITED AC 2019; 4:e94-e102. [PMID: 31211276 PMCID: PMC6554749 DOI: 10.5114/amsad.2019.85383] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2019] [Accepted: 04/24/2019] [Indexed: 12/24/2022]
Abstract
Introduction The main purpose of this work is to study prostate cancer and stroke in the United States during the years 2007-2017 and to find not only statistically significant predictors for cancer, but also a possible association between prostate cancer and stroke. Material and methods The statistical methods used to derive the results of this work are χ2 test and one-way analysis of variance (ANOVA), in order to check the statistical significance of prostate cancer in relation to socio-economic factors of patients. In addition, a multivariate logistic regression analysis was used with the odds ratio (OR) to find statistically significant prognostic factors for both prostate cancer and stroke. Results According to multiple logistic regression analysis, males who are unemployed but have worked previously have 16 times higher risk of developing prostate cancer, while widowed men have five times higher risk for the occurrence of this type of cancer. In addition, marital status and employment proved to be also prognostic risk factors for stroke. Conclusions Our results describe for the first time the importance of deprivation (of work and partner) as a primary prognostic risk factor for cancer. Moreover, the same factor proved to be the primary prognostic risk factor for stroke as well as for prostate cancer, a fact that implies a possible link between cancer and stroke.

Abstract
The American Urological Association, American Cancer Society, and American College of Physicians recommend that patients and providers make a shared decision with respect to prostate-specific antigen (PSA) testing for prostate cancer (PCa). The goal of this study is to determine the extent of patient-provider communication for PSA testing and treatment of PCa and to examine the patient specific factors associated with this communication. Using recent data from the Health Information National Trends Survey, this study examined the association of patient characteristics with four domains of patient-provider communication regarding PSA test and PCa treatment: (1) expert opinion of PSA test, (2) accuracy of PSA test, (3) side effects of PCa treatment, and (4) treatment need of PCa. The current results suggested low level of communication for PSA testing and treatment of PCa across four domains. Less than 10% of the respondents report having communication about all four domains. Patient characteristics like recent medical check-up, regular healthcare provider, global health status, age group, marital status, race, annual household income, and already having undergone a PSA test are associated with patient-provider communication. There are few discussions about PSA testing and PCa treatment options between healthcare providers and their patients, which limits the shared decision-making process for PCa screening and treatment as recommended by the current best practice guidelines. This study helps identify implications for changes in physician practice to adhere with the PSA screening guidelines.

J Racial Ethn Health Disparities 2016; 4:10.1007/s40615-016-0305-1. [PMID: 27864809 DOI: 10.1007/s40615-016-0305-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2016] [Revised: 10/17/2016] [Accepted: 10/18/2016] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Black men are more likely to be diagnosed with prostate cancer, with higher stage and higher grade at presentation. Evidence suggests that for education in health promotion behaviors (such as screenings) in early adult years, young Black men can be better equipped to make informed decisions in later years. OBJECTIVE Using the theory of reasoned action (TRA), we assessed the intention of young Black men to screen for prostate cancer when it is recommended and determined its correlates. METHODS This was a cross-sectional study of 267 Black men aged 18 to 40 years. A 47-item questionnaire collected information on demographics/personal factors, attitudes toward prostate cancer screening, social influence, comfortability with prostate examinations, cues to action, health screening experiences, knowledge of prostate cancer and screening, and intention. Descriptive statistics were calculated for all variables and hierarchical logistic regression was employed to determine significant predictors of prostate cancer screening intentions. RESULTS The regression model accounted for 46% of the variance in intention (p < 0.01), with excellent perception of health, having private or public health insurance, longer regular source of care, positive attitude, positive social influence, positive cues to action, and higher knowledge levels being significant predictors of intentions. CONCLUSION This study provides support for the use of TRA in predicting prostate cancer screening intentions among young Black men when it is recommended by a physician. Findings may inform the development of empirical-based interventions to educate and inform at-risk young Black men about the pros and cons of prostate cancer screening so that they can make informed decision on screening when recommended later in life.

Abstract
Prostate cancer (PC) screening remains controversial. We investigated whether screening reduces the difference in prostate cancer risk by socioeconomic status (SES). In 1996-2011, a total of 72,139 men from the Finnish Randomized Study of Screening for Prostate Cancer were analyzed. Outcome measures were PC incidence, mortality, and participation in screening. SES indicators were educational level, income, and home ownership status (data obtained from the Statistics Finland registry). The mean duration of follow-up was 12.7 years. Higher SES was associated with a higher incidence of low- to moderate-risk PC but with a lower risk of advanced PC. Higher education was associated with significantly lower PC mortality in both control and screening arms (risk ratio = 0.48-0.69; P < 0.05). Higher income was also associated with lower PC mortality but only in the control arm (risk ratio = 0.45-0.73; P < 0.05). There were no significant differences in SES gradient by arm (Pinteraction = 0.33 and Pinteraction = 0.47 for primary vs. secondary education and primary vs. tertiary education, respectively; Pinteraction = 0.65 and Pinteraction = 0.09 for low vs. intermediate income and low vs. high income, respectively; and Pinteraction = 0.27 among home ownership status strata). Substantial gradients by SES in PC incidence and mortality were observed in the control arm. Higher SES was associated with overdiagnosis of low-risk PC and, conversely, lower risk of incurable PC and lower PC mortality. Special attention should be directed toward recruiting men with low SES to participate in population-based cancer screening.

Abstract
PURPOSE The purposes of the study were to examine the prevalence of prostate cancer screening (PCS) in the United States and to identify predictors of PCS guided by Andersen's Behavioral Model of Health Services Use (ABM). METHODS PCS rates were analyzed in men (aged ≥40y) using 2014 data from the Behavioral Risk Factor Surveillance System. Descriptive analysis was conducted using sampling weights to determine the prevalence of PCS (i.e., had a prostate-specific antigen test). Multiple logistic regression within the framework of ABM was used to identify predictors of PCS. The ABM variables of predisposing (e.g., age), enabling (e.g., health insurance), and need (e.g., comorbidities) comprised the independent variables. RESULTS Among the 131,415 men, 62.4% (N = 82,014) reported that they had a prostate-specific antigen test in the last 2 years. Among predisposing factors, age, education, income, and employment status were significantly associated with undergoing PCS. Informed decision-making process, health care coverage, regular health care provider, and length of time since last routine checkup were significant enabling factors. Health care provider recommendation and previous cancer diagnosis were significant need factors. CONCLUSIONS Most older men in the United States had previously engaged in PCS. Several ABM variables were predictive of PCS and should be considered when developing future strategies to encourage PCS in at-risk men with the recommended life expectancies. Such strategies should also ensure that the decision to undergo PCS is an informed process between patients and their health care providers.

Abstract
OBJECTIVE The aim of this study was to determine whether educational length affects prostate-specific antigen (PSA) testing and the time to prostate biopsy for men with raised PSA values. MATERIALS AND METHODS Using register data on all men in Stockholm County in 2013 (n = 1,052,841), the limited-duration point prevalence of PSA testing and time between test and prostate biopsy or repeat testing were analysed. Patterns of follow-up were assessed using Kaplan-Meier product limit estimators and Cox proportional hazard models. Educational length was categorized as short (≤ 9 years), intermediate (10-12 years) or long (≥ 13 years). RESULTS PSA testing increased with educational length in all age groups. Among men aged 50-69 years, 61% with long and 54% with short education had had a PSA test within the preceding 10 years (p < 0.001). In men with PSA 4-10 ng/ml, 40% [95% confidence interval (CI) 38-41] with long and 27% (95% CI 26-29) with short education underwent a prostate biopsy within 12 months. After adjusting for PSA level and age, educational length was still associated with the chance of having a prostate biopsy in men with PSA 4-10 ng/ml (hazard ratio 1.22, 95% CI 1.12-1.31), but not in men with higher PSA values. CONCLUSION PSA testing increased with educational length. Men with long education were more likely to have a prostate biopsy after an increased PSA value below 10 ng/ml than men with short education. These differences may contribute to the worse prostate cancer outcomes observed among men with lower socioeconomic status.

Abstract
East and South Asian male immigrants show markedly low odds of prostate cancer screening as compared to U.S.-born men. However, knowledge about these immigrants' culture-based screening behavior and barriers to screening is extremely limited. This study investigates factors influencing receipt of prostate cancer screening among Korean American immigrant men, particularly investigating culture's impact on screening behaviors. Data were collected through a convenience and purposive sampling technique from 134 Korean American males aged 50 and older recruited in New York City. A structured questionnaire was used and cultural variables were measured by adopting items from Tang and colleagues' work. Approximately 60 % of the sample had received a prostate-specific antigen (PSA) test in their lifetime, and of these, about 66 % reported having done so in the previous 12 months. Logistic regression analysis revealed that a crisis-oriented intervention approach was associated with a substantially reduced likelihood of screening. A positive correlation was noted between the use of Eastern medicine and PSA test receipt. Further analysis revealed a significant interaction effect between use of Eastern medicine and age in predicting PSA test uptake. Culture-specific intervention strategies for increasing prostate cancer screening in this group are discussed, with particular attention to increasing pertinent health literacy. Health professionals should consider the cultural domain when working with Korean immigrant men in order to provide culturally competent care.

Abstract
OBJECTIVES There are conflicting recommendations regarding the use of prostate specific antigen (PSA) as a screening test. Integral to this debate is an understanding of who is currently being tested. The purpose of this study was to provide a detailed account of PSA testing practices in a major Canadian city (Calgary, Alberta) and to identify variables that may affect access to the PSA test. DESIGN AND METHODS PSA test counts were retrieved from Calgary Laboratory Services' Laboratory Information System from January 1, 2011 to December 31, 2011. A total of 75,914 individual PSA tests were included in our analysis. The frequency of PSA testing was plotted onto a dissemination area map of Calgary using ArcGIS software. Associations with sociodemographic variables were tested using Poisson regression. RESULTS The median PSA value was 0.93 μg/L and the median age at collection was 58 years. Forty-three percent of men aged 60-69 received a PSA test. Visible minority status 'Black' (P=0.0002) and Métis status (P=0.0075) were associated with lower PSA testing frequencies, while median household income (P=<0.0001) and university education (P=<0.0001) were associated with higher PSA testing frequencies. CONCLUSION There are areas in Calgary which are significantly over or under tested relative to the mean. The amount of PSA testing in men <50 years of age is increasing, which is contrary to PSA testing guidelines.

Abstract
BACKGROUND Prostate cancer incidence has risen considerably in recent years, primarily due to Prostate Specific Antigen (PSA) testing in primary care. The objective of this study was to investigate associations between PSA testing and the psychological and physical health, and healthcare utilisation of men in a population where PSA testing is widespread. METHODS A cross-sectional study was carried out in a population-representative sample of men ≥ 50 years enrolled in The Irish Longitudinal Study on Ageing (TILDA). TILDA participants underwent structured interviews, health assessments and completed standardised questionnaires. Men were classified as ever/never having received a PSA test. Multivariate logistic regression (Odds Ratios (OR) and 95% Confidence Intervals (CI) was used to determine associations between PSA testing, and men's psychological and physical health and healthcare utilisation. RESULTS This analysis included 3,628 men, 68.2% of whom ever had a PSA test. In adjusted analysis, men with sub-threshold depression were significantly less likely to have had a PSA test, (OR=0.79, 95% CI 0.64-0.97). Likelihood of having a PSA test was inversely associated with anxiety, but this was not significant (OR=0.79, 95% CI 0.57-1.09). Frailty (OR=0.61, 95% CI 0.31-1.05) and eligibility for free primary care (OR=0.63, 95% CI 0.52-0.77) were also inversely associated with PSA testing. Positive associations were observed between PSA testing and more chronic illnesses (OR=1.11, 95% CI 1.05-1.19), more primary care visits (OR=1.03, 95% CI 1.01-1.05) and preventative health practices, including cholesterol testing and influenza vaccination (OR=1.35, 95% CI 1.13-1.60). CONCLUSIONS Men's psychological and physical health and their healthcare utilisation are associated with PSA testing in primary care. The association between poorer psychological health, in particular sub-threshold depression, and reduced likelihood of PSA testing in primary care requires further investigation. These findings may have wider implications for other cancer screening.

Abstract
Background: Prostate-specific antigen test and digital rectal examination are considered important screening methods for early detection of prostate cancer. However, the utilization of prostate cancer screening varies widely and there is limited knowledge of the predictors of utilization. Methods: Self-reported prostate cancer screening utilization within the last 2 years was investigated among 11,162 black and non-black North American Seventh-day Adventist men, aged 50-75 years, with different dietary patterns and lifestyle characteristics. Results: Blacks were more likely to screen for prostate cancer than non-blacks (Odds Ratio (OR)=1.38 (95% confidence interval (CI): 1.20-1.57). Those with a vegetarian diet, especially vegans, were less likely to follow screening guidelines, particularly among non-Blacks: vegans (OR=0.47, 0.39-0.58), lacto-ovo-vegetarians (OR=0.75, 0.66-0.86), and pesco-vegetarians (OR=0.74, 0.60-0.91) compared to non-vegetarians after adjusting for age, BMI, marital status, education, income, and family history of cancer. Trends for dietary patterns remained unchanged after stratification on age, family history of cancer, education, personal income, marital status, and BMI. Among black men, diet patterns showed no significant associations with utilization of prostate cancer screening, although vegans tended to underutilize screening compared to non-vegetarians (OR=0.70, 0.44-1.10). Conclusions: Vegetarians, especially non-black vegans, are less likely to follow recommended prostate cancer screening guidelines. The effect of diet was attenuated, and not statistically significant, among black men. Impact: Since only about 60% of US men follow prostate cancer screening guidelines, it is important to study reasons for non-compliance in order to increase utilization of preventive measures against prostate cancer.

Abstract
BACKGROUND This study was carried out to identify racial/ethnic differences in predictors of prostate-specific antigen (PSA) screening in a group of prostate cancer patients. METHODS In this cross-sectional study, a total of 935 prostate cancer patients were recruited from the Texas Medical Center, Houston, between 1996 and 2004. It included 372 Caucasians, 346 African Americans and 217 Hispanics. A structured questionnaire was used to collect data on socio-demographic and life-style related variables, and self-reported PSA screening history through personal interview. RESULTS African American (54.4%) and Hispanic patients (42.3%) were significantly less likely (p = 0.004 and p < 0.001, respectively) to report having had PSA screening than Caucasian patients (63.2%). Only annual check-up was found to be a significant predictor of PSA screening in Hispanics. Among Caucasians, education and annual check-up were significant predictors of PSA screening; whereas in African Americans, education, annual check-up, marital status and BMI were significant predictors of PSA screening. CONCLUSIONS The rates of PSAscreening and its predictors varied by race/ethnicity in this tri-ethnic population. Health-education programs and culturally appropriate educational outreach efforts, especially targeted for high-risk groups, are needed to reduce these disparities.

Abstract
Emotional and cognitive characteristics have been studied in the context of women's cancer screening but have received scant attention in the study of men's screening behavior. Researchers know little about how such factors interact to predict screening or whether digital rectal examination (DRE) and prostate specific antigen (PSA) screens are predicted by the same characteristics. This study examines the relevance of emotional and cognitive characteristics to DRE and PSA screening among 180 U.S.-born African American, U.S.- born European American, and immigrant Jamaican men. The study identifies the expected effects in which fear is negatively related and efficacy beliefs positively related to DRE and PSA screening. Greater efficacy and (marginally) knowledge appear to "offset" the negative impact of fear on screening, and fear appears particularly relevant to DRE frequency. Results are discussed in terms of their implications for the development of health belief and self-regulatory models in the context of prostate cancer screening among minority men.

Abstract
OBJECTIVE The Lifetime Drinking History (LDH) has been used to examine alcohol use throughout the life span. Given its retrospective nature, it is important to examine the validity of the assessment. METHOD Building on previous work establishing the reliability and validity of the LDH, the current study examined a sample of 1,295 men in the Vietnam Era Twin Registry. The men were assessed retrospectively with the LDH in 2000, at an average age of 51. The drinking patterns of these same men were also assessed prospectively in four prior studies, taking place in 1987, 1990, 1992, and 1995. RESULTS Validity of the LDH was examined by comparing the correspondence between the prospective and retrospective quantity-frequency measures and reported age at first regular drinking. Correlations between the retrospective and prospective assessments were high for age at first regular drinking (.42-.58) and quantity-frequency measures (.47-.69), although some mean differences in the amount of consumption existed. CONCLUSIONS Results support the use of the LDH in reporting phases of drinking across the life span.

Abstract
Fears regarding prostate cancer and the associated screening are widespread. However, the relations between anxiety, cancer worry, and screening fear and screening behavior are complex, because anxieties stemming from different sources have different effects on behavior. In differentiating among anxieties from different sources (trait anxiety, cancer worry, and screening fear), we expected that cancer worry would be associated with more frequent screening, whereas fear of screening would be associated with less frequent screening. Hypotheses were tested in a sample of 533 men (ages 45-70 years) recruited using a stratified cluster-sampling plan. Men provided information on demographic and structural variables (age, education, income, marital status, physician discussion of risk and screening, access, and insurance) and completed a set of anxiety measures (trait anxiety, cancer worry, and screening fear). As expected, two-step multiple regressions controlling for demographics, health insurance status, physician discussion, and health-care system barriers showed that prostate-specific antigen and digital rectal examination frequencies had unique associations with cancer worry and screening fear. Specifically, whereas cancer worry was associated with more frequent screening, fear of screening was associated with less frequent screening at least for digital rectal examination; trait anxiety was inconsistently related to screening. Data are discussed in terms of their implications for male screening and the understanding of how anxiety motivates health behaviors. It is suggested that understanding the source of anxiety and the manner in which health behaviors such as cancer screenings may enhance or reduce felt anxiety is a likely key to understanding the associations between anxiety and behavioral outcomes.

Abstract
PURPOSE This research compiled and analyzed the data of two cohorts of women veterans who either served in Vietnam ("Vietnam veteran" cohort, n = 4586) or served elsewhere during the Vietnam War ("non-Vietnam veteran" cohort, n = 5325). All cause and cause-specific mortality were compared between Vietnam and non-Vietnam veteran cohorts, to the U.S. population, and to earlier research. Similar analyses were performed for nurses only. METHODS Vital status was determined through December 31, 2004, using primarily the U.S. Department of Veterans Affairs beneficiary file and the Social Security Administration Death Master File. Selected data were submitted to the National Center for Health Statistics for merging with the National Death Index to obtain cause of death. Cox proportional hazard analysis modeling was used to obtain adjusted relative risks (ARR). SEER( *)Stat software was used to compute standardized mortality ratios (SMR) for comparisons to the U.S. population. RESULTS Women Vietnam veterans showed a significant deficit (ARR = 0.78, 95% confidence interval [CI] 0.62-0.98) in circulatory system disease relative to non-Vietnam veterans, but significant deficits also were observed when the Vietnam and non-Vietnam cohorts were each compared with women in the U.S. population (SMR = 0.65, 95% CI 0.54-0.77; SMR=0.82, 95% CI 0.73-0.93, respectively). Vietnam veterans had significantly lower mortality than women in the U.S. population for all causes (SMR = 0.87, 95% CI 0.80-0.94). Vietnam veterans were at significantly greater risk of mortality from motor vehicle accidents than non-Vietnam veterans (ARR = 2.60, 95% CI 1.22-5.55) and this appeared to be specific to service in Vietnam based on comparisons to the U.S. population. Patterns did not differ greatly for the analysis on nurse veterans or to earlier mortality studies of these cohorts. CONCLUSION Mortality from motor vehicle accidents was significantly associated with service in Vietnam. Mortality patterns generally resembled those reported on in the past.

Abstract
OBJECTIVE To evaluate the effect of medical insurance coverage on health-related quality of life (HRQoL) outcomes in men newly diagnosed with prostate cancer, as insurance status has been shown to be related to clinical presentation, and types of treatments received for localized prostate cancer, but the relationship of insurance and QoL has not been explored sufficiently. PATIENTS AND METHODS Data from the Cancer of the Prostate Strategic Urological Research Endeavor (CaPSURE), a national longitudinal database registry of men with prostate cancer, were used for this study. Men who were newly diagnosed at entry to CaPSURE and completed one questionnaire before treatment, and one or more afterwards, were included. Insurance groups specific to age distribution of the study population were assessed, i.e. Medicare, preferred provider organizations (PPOs), health maintenance organizations (HMOs), fee for service (FFS), and the Veterans Administration (VA) for the younger group, and Medicare only, Medicare plus supplement (+S), and HMO/PPO for the older group. Associations between patients' clinical and sociodemographic characteristics and insurance status were evaluated by chi-square and analysis of variance. Relationships between insurance status and HRQoL outcomes over time were evaluated by multivariate mixed model. RESULTS Of 2258 men who met the study criteria, 1259 were younger and 999 were older than 65 years. More than half of the younger patients belonged to an HMO or PPO (42.2% and 32.5%, respectively), with the remainder distributed between Medicare, FFS and VA. In the older group most men belonged to Medicare only and the Medicare +S groups (22.4% and 58.8%, respectively). There was greater variation in clinical risk categories at presentation by insurance groups in the younger group. In the multivariate analysis, insurance status was significantly associated with changes in most HRQoL outcomes over time in the younger group, while in the older patients the effect of insurance diminished. Men in the VA and Medicare systems had lower scores at baseline and a steeper decline in Physical Function, Role Physical, Role Emotional, Social Function, Bodily Pain, Vitality, and General Health domains over time, controlling for type of initial treatment received, timing of HRQoL assessment, number of comorbidities, clinical risk at presentation, and income. CONCLUSION Insurance was independently related to changes in a wide range of HRQoL outcomes in men aged <65 years treated for prostate cancer. With the latest advances in early diagnosis and treatment of prostate cancer, clinicians and researchers should be aware of the specific groups of patients who are more vulnerable to the adverse effects of treatment and subsequent decline in functioning. The present findings could provide important tools for understanding the process of recovery after treatment for prostate cancer, and identifying needs for specific services.

Abstract
BACKGROUND Very few data are available on the determinants of PSA testing in Canada, and it is a matter of debate whether prostate-specific antigen (PSA) screening in asymptomatic men age 50 and older with no risk factors for prostate cancer is useful. If PSA screening is introduced into the periodic health examination, it will be important to know what factors influence its use. OBJECTIVES The purpose of this study is to determine the factors associated with PSA testing among asymptomatic men age 50 and older participating in the Tomorrow Project in Alberta. METHODS The Tomorrow Project is a population-based cohort study with over 11,000 participants accrued in Alberta since February 2003. Information was collected on medical history, sociodemographic factors, health status and lifestyle characteristics. This analysis includes 2136 men 50 years of age and older. The independent association between various factors and recent PSA screening is estimated using logistic regression. RESULTS Approximately 50% of of the study group had received one or more PSA tests in their lifetime. Of these, 58% were asymptomatic for prostate disease at the time of their most recent PSA test. Variables independently associated with recent PSA screening for prostate cancer in this population include older age (>/= 65 versus < 55 years: adjusted odds ratio [OR] 2.60; 95% confidence interval [CI] 1.77-3.83), higher income (>/= $80,000 versus < $20,000, OR 1.97; 95% CI 1.09-3.55), region of health care delivery, perception of health status (good versus excellent health status; OR 0.65, CI 0.43-0.96], increased number of chronic health conditions (OR 1.73, 95% CI 1.10-2.71), and history of colorectal cancer screening with fecal occult blood test (OR 2.21; 95% CI 1.73-2.83). CONCLUSIONS An increasing proportion of men in Alberta are receiving a PSA test. A number of significant predictors of having a PSA test were identified, suggesting that factors other than having a clinical indication for prostate disease can influence decisions about PSA screening.

Abstract
PURPOSE Despite stage migration as a result of screening, many individuals are diagnosed each year with metastatic (M+), as opposed to localized (M0), prostate cancer. This study describes features that characterize patients with M+ compared to those diagnosed with M0 disease. MATERIALS AND METHODS Patients enrolled in the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE), a national, longitudinal registry of men with prostate cancer, formed the basis of this study. The prevalence, and changes with time, of patients with M+ and M0 cancer by clinical and sociodemographic characteristics were examined. RESULTS Of 10,113 patients diagnosed between 1990 and 2003, 266 (2.6%) had M+ disease at diagnosis. From 1990 to 1997, 4.2% of 4020 total patients had M+ versus 1.6% of 6093 total patients diagnosed between 1998 and 2003 (odds ratio 0.34; 95% confidence interval 0.24-0.48; P < 0.0001). In univariate analysis, advanced age, higher prostate-specific antigen, Gleason grade, black race, lower income, and lower educational level were associated with M+ versus M0 disease (P < 0.01). However, in multivariate analysis, only higher serum prostate-specific antigen and higher Gleason grade, and not the sociodemographic variables, remained associated with M+ disease (P < 0.01). Patients with M+ diagnosed between 1998 and 2003 are more likely to harbor high-grade (Gleason > or =8) primary tumors (62% vs. 45%, P = 0.02) than those diagnosed between 1990 and 1997. No changes in age, race, education, insurance status, or income were observed in the early versus late era. CONCLUSIONS These findings show a reduction in the incidence of metastatic disease at initial prostate cancer diagnosis. Furthermore, biologic, rather than socioeconomic, factors are associated with this type of disease presentation.

Abstract
Rates of prostate cancer screening are known to vary among the major ethnic groups. However, likely variations in screening behavior among ethnic subpopulations and the likely role of psychological characteristics remain understudied. We examined differences in prostate cancer screening among samples of 44 men from each of seven ethnic groups (N = 308; U.S.-born European Americans, U.S.-born African Americans, men from the English-speaking Caribbean, Haitians, Dominicans, Puerto Ricans, and Eastern Europeans) and the associations among trait fear, emotion regulatory characteristics, and screening. As expected, there were differences in the frequency of both digital rectal exam (DRE) and prostate-specific antigen (PSA) tests among the groups, even when demographic factors and access were controlled. Haitian men reported fewer DRE and PSA tests than either U.S.-born European American or Dominican men, and immigrant Eastern European men reported fewer tests than U.S.-born European Americans; consistent with prior research, U.S.-born African Americans differed from U.S.-born European Americans for DRE but not PSA frequency. Second, the addition of trait fear significantly improved model fit, as did the inclusion of a quadratic, inverted U, trait fear term, even where demographics, access, and ethnicity were controlled. Trait fear did not interact with ethnicity, suggesting its effect may operate equally across groups, and adding patterns of information processing and emotion regulation to the model did not improve model fit. Overall, our data suggest that fear is among the key psychological determinants of male screening behavior and would be usefully considered in models designed to increase male screening frequency.

Abstract
BACKGROUND The net benefits and harms of prostate cancer screening with the prostate-specific antigen (PSA) test are uncertain, and professional organizations recommend that physicians discuss these uncertainties with patients before initiating screening. Using a nationally representative sample of men reporting past PSA screening, we aimed to determine the extent to which screening was initiated by physicians and preceded by physician-patient discussions. METHODS Cross-sectional analysis of data from the 2000 National Health Interview Survey; 2,676 men aged 40 and older underwent PSA screening and met study inclusion criteria. We analyzed the proportions of men for whom PSA screening was (1) was initiated by the physician versus the patient, and (2) preceded by discussions about the test's advantages and disadvantages. RESULTS Overall, 74% (95% CI=71.8-76.0) of recipients reported that PSA screening was initiated by their physician, and the proportion increased with advancing age, declining health status, lack of family history of prostate cancer, presence of a usual source of medical care, and non-Hispanic ethnicity. Sixty-five percent (95% CI=63.1-67.1) of screening recipients reported prescreening discussions with their physicians. Discussions were more common with physician-initiated screening than with patient-initiated screening, and among patients reporting a usual source of medical care, non-blue-collar occupation, and black race. CONCLUSIONS Among U.S. men receiving PSA screening, screening is usually initiated by physicians, frequently in men relatively less likely to benefit from it, and often without prior discussion of the test's advantages and disadvantages. Further examination of the PSA decision-making process among screened and unscreened men is warranted.

Abstract
OBJECTIVE African-Americans (AA) are more likely than Caucasians (CA) to be diagnosed with advanced prostate cancer, perhaps due to delayed detection. We investigated racial differences in prostate cancer screening according to age and socioeconomic and demographic indices in a large and predominantly low-income population. METHODS In-person interviews were conducted with 12,552 men, 84% AA, recruited during 2002 through 2004 from 25 community health centers in the southern United States. Prostate specific antigen test (PSA) and digital rectal examination (DRE) histories, and socioeconomic and demographic indices (i.e., education, household income, health insurance, and marital status) were determined. Odds ratios (OR) from logistic regression summarized the screening and race association as a function of age, while controlling for socioeconomic status (SES). RESULTS Racial differences in screening prevalence varied with age. Of men older than 65 years, CA were significantly more likely to report a PSA test (OR = 1.4) or DRE (OR = 1.5) within the past 12 months. However, these disparities were reduced with control for SES (PSA: OR =1.2; DRE: OR = 1.3, P > 0.05). In contrast, at ages younger than 65, CA were equally or less likely to have received a recent PSA test or DRE, particularly at ages 45-49 years (PSA: OR = 0.7; DRE: OR = 0.9), with little change after SES adjustment. CONCLUSIONS Consistent with several screening recommendations, younger AA men, especially those younger than age 50, are more likely than CA to have had a recent PSA test or DRE, independent of SES. Of men older than age 65, less frequent use of screening among AA than CA seems partly attributable to SES and factors other than race.

Abstract
Usando el Modelo de Creencias en Salud se exploraron creencias sobre el examen digital rectal como tamiz para cáncer en la próstata, antecedente e intención de práctica en hombres de 45 a 64 años de edad de Cali, Colombia. A los 267 participantes se les aplicó un cuestionario, previa selección mediante muestreo proporcional por cuotas. Después de un análisis univariado y bivariado se estableció que sólo un 25,8% de los participantes se había sometido previamente al examen digital rectal y 68,1% tenía intención de hacerlo en los siguientes 12 meses. Diferencias significativas (p < 0,05) fueron halladas entre antecedente de práctica y nivel de escolaridad, estrato socioeconómico, afiliación al sistema de salud, percepción de susceptibilidad a la enfermedad, percepción de barreras y beneficios. Se encontraron diferencias significativas (p < 0,05) entre intención de práctica y afiliación al sistema de salud, percepción de severidad de la enfermedad y percepción de barreras. Dado el bajo antecedente e intención de práctica del examen, los resultados podrían contribuir a mejorar las estrategias para incrementar su práctica a nivel local.

Abstract
OBJECTIVES Most previous studies of predictors for participation in prostate-specific antigen (PSA) screening for prostate cancer have been conducted in purposive samples or clinical settings. This population-based study identified factors associated with documented PSA screening among health fair participants. STUDY DESIGN Cross-sectional survey of 2098 Nebraskan men aged 35 years and older who participated in a health fair in central and eastern Nebraska in 1993. METHODS All participants were offered a PSA screening and a questionnaire to collect information on demographics, family medical history, lifestyle factors and self-perceived health status. Predictors of PSA screening were estimated by odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Men were more likely to accept the PSA screening if they were older than 50 years of age (OR=3.1; 2.4-3.9), had a higher income (OR=1.5; 1.1-2.1), were currently employed (OR=1.4; 1.0-2.5), perceived their health status as good (OR=1.1; 0.8-1.5) or excellent (OR=1.4; 1.0-2.1), and believed that they themselves, rather than physicians, should be responsible for their health (OR=1.3; 1.0-1.7). Compared with men aged 50-59 years, the ORs of participation were 0.8 (0.6-1.1) for age 60-69 years and 0.7 (0.5-1.1) for age 70+ years. Decision making was not related to education, marital status or body mass index. Predictors of screening remained unchanged when analysis was limited to men aged 50 years and over, whereas only high income and non-smoking status predicted participation among men younger than 50 years of age. CONCLUSIONS Age, income, employment status, perceived control of health and perceived heath status were related to participation in PSA screening for prostate cancer, particularly in men older than 50 years of age. Willingness to receive a PSA screening among men aged 50 years and over decreased with increasing age.

BACKGROUND Rapid uptake of prostate-specific antigen (PSA) testing has occurred in the United States despite inconclusive evidence regarding mortality benefit. METHODS We examined data (n=927) from the 2003 Health Information National Trends Survey to assess prevalence of self-reported PSA use and its association with patients' decision making. RESULTS Over half (55.2%) the sample reported ever having had a PSA test. Men aged 65-74 (OR=2.53, 1.49-4.31), with some college (OR=2.41, 1.22-4.77) or college degrees (OR=5.01, 2.53-9.90) were more likely to have had PSA tests, while men without health insurance (OR=0.32, 0.12-0.88) or a usual source of care (OR=0.35, 0.22-0.54) were less likely. In a model including healthcare provider communication and information seeking, men who reported that providers involved them in decisions (OR=1.76, 1.02-3.03) and recommended PSA (OR=236.3, 70.5-791.4) were more likely to have had the tests. Men aged 65-74 (OR=2.30, 1.33-4.00), with college degrees (OR=2.91, 1.45-5.82), and greater information attention/seeking (OR=1.23, 1.07-1.40) were more likely to report PSA recommendations, while those without usual care were less likely (OR=0.37, 0.22-0.64). Men without usual care (OR=0.38, 0.20-0.71) and Hispanic men (OR=0.40, 0.19-0.85) were less likely to report that healthcare providers involved them in healthcare decisions. CONCLUSIONS Results emphasize the relevance of patient decision making and the importance of healthcare providers in PSA testing.

Abstract
BACKGROUND In 2000, the National Health Interview Survey (NHIS) collected information about prostate-specific antigen (PSA) test use in a representative sample of U.S. men. METHODS This study examined PSA test use in subgroups defined by personal and social characteristics. RESULTS Among men aged 50 and older with no history of prostate cancer, 56.8% reported ever having had a PSA test, 34.1% reported having had a screening PSA test during the previous year, and 30.0% reported having had three or more tests during the previous 5 years. Screening was greater among men aged 60-79 years, those with greater access to care, and those practicing other preventive behaviors. Among men in their 40s, use tended to be higher among African-American men. CONCLUSIONS The prevalence and patterns of PSA screening suggest that PSA is used like other cancer screening tests among about a third of U.S. men. Because of the lack of scientific consensus on whether prostate cancer screening is beneficial, more information is needed on how knowledgeable both patients and practitioners are about the potential benefits and harms of screening and how prostate cancer screening decisions are made.

Abstract
Abstract
First-degree relatives (FDRs) of prostate cancer patients are known to be at increased risk for the disease, yet relatively little is known about their screening behaviors. The current lack of consensus about the value of prostate cancer screening underscores the importance of examining why some men at increased risk participate in screening and others do not. In this study, variables from Protection Motivation Theory were used to identify predictors of prostate specific antigen (PSA) testing in this at-risk population. Toward this end, scales assessing perceived vulnerability, perceived severity, response efficacy, and self-efficacy for prostate cancer screening were administered to 82 unaffected male FDRs aged 40 and older. When recontacted approximately 14 months later, 50% of FDRs were found to have undergone PSA testing in the interim. Older age, prior prostate cancer screening, and a greater sense of personal efficacy about being able to undergo prostate cancer screening were found to be significant (P < 0.05) predictors of subsequently undergoing PSA testing. These findings provide partial support for the predictive validity of Protection Motivation Theory variables and suggest the importance of considering efficacy beliefs in attempting to understand decision-making about PSA testing in at-risk individuals.

Abstract
Health services research conducted over the past 25 years makes a compelling case that having health insurance or using more medical care would improve the health of the uninsured. The literature's broad range of conditions, populations, and methods makes it difficult to derive a precise quantitative estimate of the effect of having health insurance on the uninsured's health. Some mortality studies imply that a 4% to 5% reduction in the uninsured's mortality is a lower bound; other studies suggest that the reductions could be as high as 20% to 25%. Although all of the studies reviewed suffer from methodological flaws of varying degrees, there is substantial qualitative consistency across studies of different medical conditions conducted at different times and using different data sets and statistical methods. Corroborating process studies find that the uninsured receive fewer preventive and diagnostic services, tend to be more severely ill when diagnosed, and receive less therapeutic care. Other literature suggests that improving health status from fair or poor to very good or excellent would increase both work effort and annual earnings by approximately 15% to 20%.

Abstract
This study was designed to describe patient characteristics associated with having a regular source of care among all patients who received care from large urban clinics in Manitoba over a three-year period (N = 298,222). Using administrative data, patients were classified as having a regular source of care if they made 75% or more of their total ambulatory visits to the same clinic. Overall, 44.2% of patients had a regular source of care. A logistic regression showed that children and adults aged 45 and older were more likely to have a regular source of care than patients aged 18-44. Moreover, patients with a regular source of care tended to live in more affluent neighbourhoods and were healthier than individuals with no regular source of care. Systemic changes might be needed to enhance continuity of care (e.g., mechanisms to enhance access) among vulnerable segments of the population like the poor.

Abstract
BACKGROUND Identifying who is pursuing prostate-specific antigen (PSA) screening for prostate cancer is prerequisite to effectively influencing participation in PSA screening and educating people about potential screening implications and personal risk. This paper describes the relationship between select demographic and health-related factors with PSA screening. METHODS Analysis was based on 1,293 men age 40 years or older who responded to a cross-sectional random telephone survey involving 12 health districts in the state of Utah from June 1 to August 31, 1996. Independent variables were current age, race, marital status, education, household income, medical insurance, level of physical activity, intake of fruits and vegetables, receipt of psychiatric help, religious preference, church attendance, general health status, and employment. RESULTS Forty-eight percent of respondents reported having had a PSA in the past year. PSA screening in the previous year significantly increased and leveled off with age: 23.9% for ages 40-49, 51.4% for ages 50-59, 67.4% for ages 60-69, and 67.0% for ages 70+. After adjusting for age, only marital status and medical insurance were significantly related to PSA screening, with medical insurance having the largest effect. Approximately 50.6% married men and 33.5% unmarried men had a PSA in the past year. Percentages for insured and uninsured men were 49.4 and 16.6%, respectively. CONCLUSION A substantial portion of elderly men, particularly those who are married and medically insured, have had a PSA test in the past year. This information makes it possible to more effectively influence participation in PSA screening and educate people about potential screening implications and personal risk.

Abstract
The objective of this study was to examine the effect of socioeconomic status and insurance status on health-related quality of life (HRQOL) outcomes in men with prostate cancer. The design was a retrospective cohort study using multiple sites, including both academic and private practice settings. A cohort of 860 men with newly diagnosed, biopsy-proven prostate cancer of any stage was identified within CaPSURE, a longitudinal disease registry of prostate cancer patients. HRQOL was assessed with validated instruments, including the RAND 36-item Health Survey (SF-36) and the UCLA Prostate Cancer Index. Covariates included insurance status, education level, annual income, age, stage, comorbidity, Gleason grade, baseline PSA, marital status, ethnicity and primary treatment. HRQOL measurements were taken at 3-6-month intervals. Analysis of covariance was used to determine the effect of SES and insurance status on the HRQOL domains at baseline and over time. Patients with lower annual income had significantly lower baseline HRQOL scores in the all of the domains of the SF-36 and four of eight disease-specific HRQOL domains. No relationship was seen between annual income and HRQOL outcomes over time. Conversely, health insurance status was associated with HRQOL over time, but not at baseline. Health insurance status appears to have a unique effect on general HRQOL outcomes in men after treatment for prostate cancer. This study confirms the commonly held belief that patients of lower SES tend to have worse quality of life at baseline and following treatment for their disease. These findings have important ramifications for clinicians, researchers and policy makers.

Abstract
OBJECTIVES Comparisons of cancer survival in Canadian and US metropolitan areas have shown consistent Canadian advantages. This study tests a health insurance hypothesis by comparing cancer survival in Toronto, Ontario, and Honolulu, Hawaii. METHODS Ontario and Hawaii registries provided a total of 9190 and 2895 cancer cases (breast and prostate, 1986-1990, followed until 1996). Socioeconomic data for each person's residence at the time of diagnosis were taken from population censuses. RESULTS Socioeconomic status and cancer survival were directly associated in the US cohort, but not in the Canadian cohort. Compared with similar patients in Honolulu, residents of low-income areas in Toronto experienced 5-year survival advantages for breast and prostate cancer. In support of the health insurance hypothesis, between-country differences were smaller than those observed with other state samples and the Canadian advantage was larger among younger women. CONCLUSIONS Hawaii seems to provide better cancer care than many other states, but patients in Toronto still enjoy a significant survival advantage. Although Hawaii's employer-mandated health insurance coverage seems an effective step toward providing equitable health care, even better care could be expected with a universally accessible, single-payer system.
