Changes in Alcohol Consumption and Associated Variables among Older Adults in Spain: A population-based cohort study.

We examined prospective changes in drinking patterns and their associations with socio-behavioral and health status variables in older adults in Spain using data from a prospective cohort of 2,505 individuals (53.3% women) representative of the non-institutionalized population aged >60 years in Spain. Alcohol consumption was assessed at baseline (2008-10) and at follow-up (2012) with a validated diet history. At risk drinking was defined as consuming >14 g of alcohol/day on average or any binge drinking in the last 30 days; lower amounts were considered light drinking. A total of 26.5% of study participants changed their intake during follow-up. Most participants reduced alcohol intake, but 23.3% of men and 8.9% of women went from light to at risk drinking during the study period. Low social connectivity at baseline was linked to at risk drinking for both sexes. However, the observed associations between changes in social connectivity, morbidity, BMI, or dietary habits and changes in drinking patterns differed by sex. We concluded that since about a quarter of older adults in Spain consume more alcohol than recommended, identifying socio-behavioral factors associated with this behavior is key for designing health campaigns targeting excessive alcohol consumption in this vulnerable population.

Changes in health status predict changes in alcohol consumption in older adults: the Seniors-ENRICA cohort.

BACKGROUND: Some of the previously reported health benefits of low-to-moderate alcohol consumption may derive from health status influencing alcohol consumption rather than the opposite. We examined whether health status changes influence changes in alcohol consumption, cessation included. METHODS: Data came from 571 current drinkers aged ≥60 years participating in the Seniors-ENRICA cohort in Spain. Participants were recruited in 2008-2010 and followed-up for 8.2 years, with four waves of data collection. We assessed health status using a 52-item deficit accumulation (DA) index with four domains: functional, self-rated health and vitality, mental health, and morbidity and health services use. To minimise reverse causation, we examined how changes in health status over a 3-year period (wave 0-wave 1) influenced changes in alcohol consumption over the subsequent 5 years (waves 1-3) using linear/logistic regression, as appropriate. RESULTS: Compared with participants in the lowest tertile of DA change (mean absolute 4.3% health improvement), those in the highest tertile (7.8% worsening) showed a reduction in alcohol intake (ß: -4.32 g/day; 95% CI -7.00 to -1.62; p trend=0.002) and were more likely to quit alcohol (OR: 2.80; 95% CI 1.54 to 5.08; p trend=0.001). The main contributors to decreasing drinking were increased functional impairment and poorer self-rated health, whereas worsening self-rated health, onset of diabetes or stroke and increased prevalence of hospitalisation influenced cessation. CONCLUSIONS: Health deterioration is related to a subsequent reduction and cessation of alcohol consumption contributing to the growing evidence challenging the protective health effect previously attributed to low-to-moderate alcohol consumption.

Moderate alcohol drinking is not associated with risk of depression in older adults.

The scarce research on the effects of moderate alcohol consumption on mental health among older adults suggests a protective effect against depression. We prospectively examined the association between patterns of moderate alcohol consumption, depression and psychological distress, using information from 5,299 community-dwelling older adults from the ELSA and Seniors-ENRICA cohorts. A Mediterranean drinking pattern (MDP) was defined as moderate alcohol intake (<40 g/day for men; <24 g/day for women) with a preference for wine and drinking only with meals. Depression was ascertained with the 10-item Geriatric Depression Scale (GDS-10), a self-report of clinically-diagnosed depression, or being on anti-depressant medication (Seniors-ENRICA); and with the 8-item Center for Epidemiologic Studies Depression Scale (CES-D) (ELSA). Psychological distress was assessed with the General Health Questionnaire-12 (GHQ-12). Compared to never drinkers, moderate drinkers showed comparable scores on the ENRICA-GDS-10 (PRR (95%CI): 1.03 (0.84-1.26)), the ENRICA-GHQ-12 (0.88 (0.73-1.06)), the ELSA-CES-D (0.92 (0.79-1.06)) and the ELSA-GHQ-12 (0.75 (0.55-1.01). The MDP was not associated with the GDS-10 or GHQ-12 scores, or with clinically-diagnosed depression; however drinkers with a preference for wine showed an increased number of psychological distress symptoms (1.31 (1.03-1.66)). In conclusion, we found no consistent protective association between moderate alcohol consumption and depression in older adults.

Unhealthy eating behaviors and weight gain: A prospective study in young and middle-age adults.

OBJECTIVE: Guidelines for obesity prevention recommend reducing certain unhealthy eating behaviors (UEB). However, the association between UEB and weight gain is uncertain. METHODS: Prospective cohort with 1,638 individuals aged 18-60 years was recruited in 2008-2010. UEB assessed at baseline were: not planning how much to eat, consuming pre-cooked/canned food, buying snacks, eating in fast-food restaurants, not choosing low-calorie foods, not removing visible fat from meat or skin from chicken, and eating while watching TV or seating on a sofa. Participants were followed up through 2012 to assess weight change. RESULTS: Compared to reporting 0-2 UEB, the multivariate odds ratios (95% confidence interval) for gaining ≥3 kg were 0.97 (0.74-1.28) for 3-4 UEB and 1.61 (1.09-2.39) for ≥5 UEB, P-trend = 0.07. Results were similar for gaining ≥5 kg. The three UEB with the strongest associations with weight gain were: 1) not planning the amount of food to eat, 2) eating at fast-food restaurants, and 3) eating while watching TV; compared to having none of these three behaviors, the odds ratio (95% confidence interval) for gaining ≥3 kg was 1.54 (0.77-3.08) for 1 UEB, 1.70 (0.85-3.37) for 2 UEB, and 2.75 (1.28-5.90) for 3 UEB, P-trend = 0.007. Similar results were obtained for gaining ≥5 kg. CONCLUSIONS: Several UEB are associated with weight gain.

Contribution of health behaviours and clinical factors to socioeconomic differences in frailty among older adults.

BACKGROUND: To examine the association between socioeconomic status (SES) and risk of frailty, and to assess whether behavioural and clinical factors (BCF) mediate this association. METHODS: Cohort of 1857 non-institutionalised individuals aged ≥ 60 years recruited in 2008-2010 and followed through 2012. Education, occupation, and BCF were ascertained at baseline, and incident frailty was assessed at follow-up with the Fried frailty criteria. RESULTS: Men showed no differences in frailty risk by education or occupation. Compared with women with university education, the adjusted OR (aOR) adjusted for age and the number of frailty criteria at baseline for incident frailty in women with primary or lower education was 3.02 (95% CI 1.25 to 7.30); once fully adjusted for BCF, the OR was 2.00 (95% CI 0.76 to 5.23). No alcohol intake (vs light-moderate), longer time spent watching TV, less time spent reading, and a higher frequency of obesity, depression and musculoskeletal disease in those with primary or lower education accounted for most of the decline in OR. BCF explained 50.5% of the excess frailty risk associated with lower education. The aOR of frailty incidence for manual versus non-manual occupation was 2.24 (95% CI 1.41 to 3.56) versus a fully aOR of 2.05 (95% CI 1.24 to 3.37). BCF explained 15.3% of the association, with individual mediators being similar to those for education-related differences. CONCLUSIONS: A lower education or a manual occupation was associated with higher frailty risk in older women. These associations were partly explained by lower alcohol consumption, higher sedentariness, and higher obesity and chronic disease rates in women with lower SES.

Working with cancer: health and employment among cancer survivors.

PURPOSE: Cancer affects a growing proportion of US workers. Factors contributing to whether they continue or return to work after cancer diagnosis include: age, physical and mental health, health insurance, education, and cancer site. The purpose of this study was to assess the complex relationships between health indicators and employment status for adult cancer survivors. METHODS: We analyzed pooled data from the 1997-2012 US National Health Interview Survey (NHIS). Our sample included adults with a self-reported physician diagnosis of cancer (n = 24,810) and adults with no cancer history (n = 382,837). Using structural equation modeling (SEM), we evaluated the relationship between sociodemographic factors, cancer site, and physical and mental health indicators on the overall health and employment status among adults with a cancer history. RESULTS: The overall model for cancer survivors fit the data well (χ(2) (374) = 3654.7, P < .001; comparative fit index = 0.98; root mean square error of approximation = 0.04). Although black cancer survivors were less likely to report good-to-excellent health, along with Hispanic survivors, they were more likely to continue to work after diagnosis compared with their white counterparts. Health insurance status and educational level were strongly and positively associated with health status and current employment. Age and time since diagnosis were not significantly associated with health status or employment, but there were significant differences by cancer site. CONCLUSIONS: A proportion of cancer survivors may continue to work because of employment-based health insurance despite reporting poor health and significant physical and mental health limitations. Acute and long-term health and social support are essential for the continued productive employment and quality of life of all cancer survivors.

Three-year changes in drinking patterns in Spain: a prospective population-based cohort study.

BACKGROUND: This study examined changes in alcohol drinking patterns (DP) and associated variables in a Mediterranean country. METHODS: Changes in DP between baseline (2008-2010) and follow-up (2012-2013) were examined on a Spanish population-based cohort of 2254 adults (18-59 years) using multinomial logistic regression. Heavy consumption was defined as ≥40 g/day of alcohol in men (≥24 g/day in women) and binge drinking (BD) as the intake of ≥80 g of alcohol in men (≥60 g in women) on one occasion in the previous month. Six patterns were defined: (1) non-drinkers; (2) ex-drinkers; (3) moderate drinkers without BD (MNB); (4) moderate drinkers with BD (MB); (5) heavy drinkers without BD (HNB); and (6) heavy drinkers with BD (HB). RESULTS: Overall, 45.2% of participants changed DP during follow-up. Over 24% of non-drinkers and 19.4% of ex-drinkers at baseline qualified as MNB at follow-up. The largest flow was from HNB to MNB (57.1%). Light-drinking patterns experienced the largest gains (ex-drinkers: 37.5% and MNB: 66.7%) by absorbing individuals lost by heavy-drinking patterns (MB: 50.8% and HNB: 48.4%). Men, younger individuals, and current smokers were more likely to report heavy-drinking patterns at one or both assessments. Being married or employed increased the likelihood of reporting light-drinking patterns at both surveys (p<0.05). Improving physical quality of life and exercise were associated with a shift from light- to heavy-drinking pattern during follow-up (p<0.05). CONCLUSIONS: DP in Spain changed over 3 years with a tendency to "regress" toward moderate patterns. Repeated measures of alcohol intake may reduce classification errors and biased results when examining the impact of alcohol on health.

Binge drinking in Spain, 2008-2010.

BACKGROUND: Most alcohol-related research has focused on northern and eastern Europe and the United States. Data on Mediterranean countries point to drinking patterns approaching the sporadic and excessive patterns found in northern and eastern Europe. This is the first study to estimate the prevalence of binge drinking (BD) and the joint distribution of BD, regular heavy alcohol consumption, and alcohol abuse or dependence (AAD) in a nationally representative sample of the adult population of Spain. METHODS: Cross-sectional study conducted in 2008 to 2010 with 9,130 persons aged 18 to 64 years. BD was defined as intake of ≥80 g of alcohol in men (≥60 g in women) during any drinking occasion in the previous month, with ≥3 BD episodes discriminating between frequent and sporadic BD. Regular alcohol consumption was measured with a validated diet history, and the threshold between moderate and heavy drinking was ≥40 g of alcohol/d in men (≥24 g in women). AAD was defined by a CAGE score ≥2. RESULTS: BD prevalence was 10% (95% confidence interval [CI]: 8.8 to 11.2) in men and 4.2% (95% CI: 3.5 to 4.8) in women, and proved highest among 18- to 24-year-olds (19.5% in men and 10.3% in women). During the latest BD episode, men consumed a mean of 114 g of alcohol versus 85.3 g in women; spirits accounted for 65.2 and 66.2% of total intake, respectively. The mean number of monthly BD episodes was 2.3 in men and 2 in women. Among binge drinkers, 61% were 18- to 34-year-olds, over 80% had regular moderate drinking, 25% reported frequent BD, and 22.8% reported AAD. In multivariate analyses, sporadic BD and frequent BD were associated with AAD independently of regular alcohol intake. CONCLUSIONS: Prevalence of BD in Spain is moderately high. Prevention interventions should consider that the majority of binge drinkers are young men with regular moderate consumption and no AAD traits.

Trends in Adherence to Recommended Cancer Screening: The US Population and Working Cancer Survivors.

INTRODUCTION: Over the past decade the United States (US) has seen a decrease in advanced cancer diagnoses. There has also been an increase in the number of cancer survivors returning to work. Cancer screening behaviors among survivors may play an important role in their return-to-work process. Adherence to a post-treatment cancer screening protocol increases early detection of secondary tumors and reduces potentially limiting side-effects. We compared screening trends among all cancer survivors, working survivors, and the general population over the last decade. MATERIALS AND METHODS: Trends in adherence to recommended screening were analyzed by site-specific cancer. We used the Healthy People goals as a measure of desired adherence. We selected participants 18+ years from 1997 to 2010 National Health Interview Survey for years where detailed cancer screening information was available. Using the recommendations of the American Cancer Society as a guide, we assessed adherence to cancer screening across the decade. There were 174,393 participants. Analyses included 7,528 working cancer survivors representing 3.8 million US workers, and 119,374 adults representing more than 100 million working Americans with no cancer history. RESULTS: The US population met the Healthy People 2010 goal for colorectal screening, but declined in all other recommended cancer screening. Cancer survivors met and maintained the HP2010 goal for all, except cervical cancer screening. Survivors had higher screening rates than the general population. Among survivors, white-collar and service occupations had higher screening rates than blue-collar survivors. CONCLUSION: Cancer survivors report higher screening rates than the general population. Nevertheless, national screening rates are lower than desired, and disparities exist by cancer history and occupation. Understanding existing disparities, and the impact of cancer screening on survivors is crucial as the number of working survivors increases.

Working with cancer: health and disability disparities among employed cancer survivors in the U.S.

INTRODUCTION: Approximately 40% of Americans annually diagnosed with cancer are working-age adults. Using a nationally representative database, we characterized differences in health status and occupation of working cancer survivors and persons without cancer. METHODS: Cross-sectional data pooled from the 1997-2009 US National Health Interview Survey for adults with self-reported physician-diagnosed cancer (n=22,952) and those without (n=358,495), were analyzed. Multivariable logistic regression was used to compare the health and disability status of employed cancer survivors across occupational sectors relative to workers without a cancer history and unemployed cancer survivors. RESULTS: Relative to workers with no cancer history, cancer survivors were more likely (OR; 95%CI) to be white-collar workers and less likely to be service workers. Working cancer survivors were significantly less likely than unemployed survivors, but more likely than workers with no cancer history, to report poor-fair health (0.25; 0.24-0.26) and (2.06; 1.96-2.17) respectively, and ≥ 2 functional limitations (0.37; 0.35-0.38) and (1.72; 1.64-1.80) respectively. Among employed cancer survivors, blue-collar workers reported worse health outcomes, yet they reported fewer workdays missed than white-collar workers. CONCLUSION: Blue-collar cancer survivors are working with high levels of poor health and disability. These findings support the need for workplace accommodations for cancer survivors in all occupational sectors, especially blue-collar workers.

Contextualizing the survivorship experiences of Haitian immigrant women with breast cancer: opportunities for health promotion.

PURPOSE/OBJECTIVES: To examine challenges faced by Haitian immigrant women managing a breast cancer diagnosis. RESEARCH APPROACH: Trained community health workers conducted focus groups with Haitian women who were breast cancer survivors. A grounded theory approach guided analysis of transcripts. SETTING: A large community-based organization in Miami, FL. PARTICIPANTS: 18 women took part in three focus groups. Participants were 40 years or older, were ethnically Haitian, and had been diagnosed with breast cancer 6-12 months prior to the study. METHODOLOGIC APPROACH: Data were collected as part of an ongoing community-based participatory research initiative in Little Haiti, the largest enclave of Haitian settlement in Miami, FL. Community health workers, integral to the initiative, recruited participants through their extensive social networks and community contacts. MAIN RESEARCH VARIABLES: Screening knowledge, illness beliefs, social and economic consequences of a breast cancer diagnosis, and advice for breast health education. FINDINGS: Emergent themes suggest that Haitian breast cancer survivors face multiple challenges, including misperceptions about screening guidelines, disease etiology, and risk; a reduced capacity to earn a living because of physical debility; and diminished social support. CONCLUSIONS: Future research must continue to examine the impact of breast cancer on Haitian immigrant women and identify key strategies, such as community outreach and support programs, to improve their quality of life. INTERPRETATION: Nurses can play an essential role in such strategies by providing culturally relevant clinical care and partnering with community stakeholders to define the scope and focus of public health intervention.

The prognostic role of cancer-specific beliefs among prostate cancer survivors.

OBJECTIVE: The objective of this study is to evaluate the association between cancer-specific beliefs and survival among men newly diagnosed with prostate cancer. METHODS: Based on data from a biracial cohort monitored for mortality for up to 15 years, we investigated the association between beliefs and survival among 251 men newly diagnosed with prostate cancer between 1987 and 1990. We examined patients' beliefs related to efficacy of regular checkups for detection, potential negative treatment effects, and perceived curability of cancer. Cox proportional hazards models were adjusted for sociodemographic variables, medical care measures, clinical factors, and lifestyle. RESULTS: In a fully adjusted model, not believing that most cancers can be cured was associated with an increased risk of death from any cause (Hazard Ratio = 1.62; 95% confidence interval = 1.11, 2.38). Beliefs regarding the efficacy of checkups or potential negative treatment effects were not associated with survival. CONCLUSIONS: Prostate cancer patients who reported not believing that most cancers are curable experienced poorer survival after adjusting for a wide array of prognostic factors and potential confounders. Future research to identify underlying behavioral (medical protocol adherence, lifestyle) and physiological (immune and endocrine regulation) mechanisms of this association would translate into improved intervention strategies for cancer survivors.

Cancer-specific beliefs and survival in nonmetastatic colorectal cancer patients.

BACKGROUND: Colorectal cancer (CRC) is the third leading cause of cancer mortality in the United States. Associations between cancer-specific beliefs (beliefs) and survival have been observed among other cancer populations, but similar research in CRC patients is virtually nonexistent, especially in racially diverse populations. The relationship between beliefs and survival was investigated in a cohort of African Americans and non-Hispanic whites with newly diagnosed nonmetastatic CRC, followed for up to 15 years. METHODS: The authors analyzed data from a population-based cohort of 286 individuals (115 African Americans and 171 whites, approximately 52% women) diagnosed with nonmetastatic CRC in Connecticut, 1987 to 1991. Cox proportional hazards models were adjusted for sociodemographic (age, sex, race, education, income, occupational status, marital status) and biomedical (stage at diagnosis, histological grade, treatment) variables. RESULTS: Not believing in the curability of cancer increased the risk of all-cause mortality (hazard ratio [HR], 1.59; 95% confidence interval [CI], 1.06-2.39) and CRC-specific mortality (HR, 1.65; 95% CI, 0.90-3.03; P=.10). These multivariate estimates were not altered by additional adjustment for insurance coverage, obesity, smoking, alcohol consumption, or comorbidity. Furthermore, the association between perceived curability and survival did not vary significantly by key sociodemographic or biomedical factors. Other beliefs were not associated with survival. CONCLUSIONS: Among a racially diverse cohort of men and women with CRC, believing in the curability of cancer was independently associated with survival over a 15-year period. Confirmation of the role of cancer-specific beliefs on survival and study of the potential biobehavioral mechanisms is needed. Findings may inform the design of interventions for cancer survivors.

Intake of plant foods and associated nutrients in prostate cancer risk.

Plant foods and associated nutrients may impact prostate cancer (PC) risk and survival. Therefore, we compared dietary intake, mainly plant food groups among 382 controls and 478 PC cases (373 incident and 105 prevalent cases). Caucasian controls had significantly higher daily servings of vegetables (3.4 vs. 2.5, P= 0.002) and fruits and/or fruit juices (1.6 vs. 1.3, P = 0.02) compared to African American controls. In Caucasians, incident cases reported lower intake of fiber, vitamin C, vitamin A, alpha -carotene, beta -carotene, cryptoxanthin, folate, genistein, daidzein, and fruits and/or fruit juice than controls and/or prevalent cases. In African Americans, incident cases had lower intake of alpha -carotene compared to controls and prevalent cases. Reduced PC risk was associated with the highest tertile of cryptoxanthin (OR = 0.51; 95% CI = 0.35-0.75), fiber (OR = 0.56; 95% CI = 0.35-0.89), vitamin C (OR = 0.60; 95% CI = 0.41-0.88), and fruits and/or fruit juices (OR = 0.46; 95% CI = 0.31-0.68), with significant linear trends. Increased risk of PC was associated with the highest tertile of protein (OR = 1.99; 95% CI = 1.05-3.79) and daily servings of grains (OR = 1.99; 95% CI = 1.23-3.22) with significant linear trends. In summary, we demonstrate racial/ethnic differences in dietary intake of plant foods. The significantly higher consumption of protective dietary constituents among prevalent cases compared to incident cases suggests that PC survivors may be amenable to dietary change.

Looking under the Hispanic umbrella: cancer mortality among Cubans, Mexicans, Puerto Ricans and other Hispanics in Florida.

Cancer is the second leading cause of death among Hispanics. Most of the cancer statistics available both at the state and national levels report cancer statistics for all Hispanics as an aggregate group. The goal of this paper is to provide a population-based overview of cancer mortality among Hispanics (Cubans, Mexicans, Puerto Ricans and other Hispanics) in Florida from 1990 to 2000 and to explore the demographic diversity of this growing ethnic group. The study population consisted of Hispanics and White non-Hispanics who died from cancer. Cancer mortality rates and proportion of cancer deaths by type and age at death for the selected racial/ethnic groups were calculated. Our findings indicate that the cancer death rates of the Hispanic subgroups compared favorably with those of White non-Hispanics and that cancer rates often presented for all Hispanics mask important differences between the different ethnic subgroups that fall under the Hispanic umbrella.

Explaining the race difference in prostate cancer stage at diagnosis.

Prostate cancer is the most frequently diagnosed cancer in males in the United States, accounting for an estimated 186,320 new cases in 2008. There are striking racial or ethnic differences in prostate cancer incidence and mortality rates in the United States, with Black males 1.6 times more likely to be diagnosed and 2.4 times more likely to die with prostate cancer than Whites. Stage at diagnosis is a key prognostic factor for prostate cancer survival, with African-Americans generally diagnosed at a more advanced stage. To identify factors that explain the race-stage disparity in prostate cancer, we conducted a population-based case-case study of 251 African-American (46%) and White (54%) prostate cancer cases diagnosed in Connecticut between January 1987 and October 1990. Multivariate logistic regression was used to identify potential explanatory factors, including clinical, sociodemographic, medical care, insurance, digital rectal examination screening history, and lifestyle factors. Cox proportional hazards models assessed the impact of study variables on race differences in long-term survival. Modifiable factors such as screening practice and sociodemographic factors accounted for >60% of the race difference in prostate cancer stage at diagnosis. Histologic grade (Gleason score) accounted for comparatively less. Survival analyses confirmed the importance of tumor characteristics, education, and insurance in explaining observed race differences in survival. Although cases were identified before the widespread use of prostate-specific antigen (PSA) screening, the results should also be relevant to countries that have large underserved populations and/or disparities in access to medical care and cancer screening.

Gender- and race-specific comparison of tobacco-associated cancer incidence trends in Florida with SEER regional cancer incidence data.

OBJECTIVE: Analysis of state and national tobacco-associated cancer trends is critical for the identification of high-risk regions of the country that require the attention of the public health community. This study compares Florida race- and gender-specific cancer trends with pooled data obtained from nine Surveillance, Epidemiology, and End Results (SEER-9) registries. METHODS: Age-adjusted, race- and gender-specific cancer incidence trends were evaluated using joinpoint regression analysis. Pooled, age-adjusted incidence rates and standardized incidence rate ratios were computed for each cancer for the years 1999-2003 to compare Florida to SEER-9. RESULTS: Relative to SEER-9 whites and irrespective of gender, lung cancer rates in white Floridians were elevated through the 1990s. However, lung cancer rates have recently declined at a steeper rate among white Floridians than among SEER-9 whites. For years 1999-2003, black Floridians had significantly lower rates of lung, bladder, pancreas, and kidney cancer relative to SEER-9 blacks. The opposite pattern was evident for white Floridians with significantly higher rates of lung and laryngeal cancer relative to SEER-9 whites. CONCLUSION: Progress in the reduction of tobacco-associated cancers among white Floridians lags behind the progress noted in SEER-9 registries suggesting that additional state-directed smoking prevention and smoking cessation measures are needed.

Cancer-specific beliefs and survival: a population-based study of African-American and White breast cancer patients.

OBJECTIVE: Beliefs about cancer and its treatment have been shown to influence cancer stage at diagnosis and, thus, prognosis. The association between these beliefs and survival is understudied, especially among racially/ethnically diverse populations. We investigated the relationship between cancer-specific beliefs and survival in a cohort of African-American and White women with newly diagnosed breast cancer followed for up to 15 years. METHODS: We examined beliefs about cancer detection, treatment, and curability in a population-based cohort of 145 African-American and 177 White women diagnosed with breast cancer in Connecticut, US, between 1987 and 1989. Cox proportional-hazards models were adjusted for stage at diagnosis, other biomedical variables, socio-demographic and lifestyle factors. RESULTS: In multivariate models, perceived cancer incurability was associated with a higher risk of death from any cause (hazards ratio (HR)=1.67, 95 confidence interval (CI)=1.11, 2.51). Further control for tumor characteristics, genetic alterations, access to care, and additional psychosocial factors did not alter these findings. Other cancer-specific beliefs examined here were not related to survival. CONCLUSIONS: Perceived cancer incurability is independently associated with survival among breast cancer patients in fully adjusted models. The identification of the underlying mechanisms of this association has potential for translation into intervention strategies for cancer patients.

African-American/White differences in breast carcinoma: p53 alterations and other tumor characteristics.

BACKGROUND: Despite mounting evidence that breast tumors in African-American (AA) women are more aggressive compared with breast tumors in white (W) women, little is known regarding racial/ethnic differences in genetic alterations that may be of prognostic importance. METHODS: In this population-based cohort of 322 AA women (45%) and W women (55%) who were diagnosed with breast carcinoma between 1987-1989, the authors evaluated available archived tumor tissue (n = 247 samples) for racial differences in selected genetic alterations and other prognostic indicators. Tumor characteristics were assessed by immunohistochemistry and/or expert review. RESULTS: Alterations in p53 were significantly more common in AA women compared with W women (odds ratio, 4.00; 95% confidence interval, 1.77-9.01) and remained statistically significant in models that were adjusted for disease stage at diagnosis, according to American Joint Committee on Cancer (AJCC) criteria, and for other prognostic indicators. No racial difference with regard to HER-2/neu status was observed, but alterations in c-met were more common in AA women once the model was adjusted for negative confounders (not significant). Among other tumor characteristics, significant findings included later AJCC stage and higher histologic and nuclear grade tumors in AA women. In addition, the burden of aggressive tumor characteristics was greater in AA women because they were more likely to be at high risk on multiple factors (e.g., both high histologic grade and high nuclear grade [P = 0.03] and negative status for both estrogen receptors and progesterone receptors [P = 0.01]). CONCLUSIONS: Data from this population-based cohort confirmed that breast tumors in AA women most likely are more aggressive compared with breast tumors in W women and offer new evidence for possible racial/ethnic differences with regard to p53 alterations.

Prognostic significance of psychosocial factors in African-American and white breast cancer patients: a population-based study.

BACKGROUND: It has been suggested that psychosocial factors, such as coping and emotional support, influence cancer survival, but results have been inconclusive. Given the scarce data from racially/ethnically diverse populations, the authors investigated the prognostic significance of selected psychosocial variables in a cohort of African-American women and white women with breast cancer. METHODS: The authors examined the effects of coping styles, perceived emotional support, fatalism, and health locus of control on survival for a population-based cohort of 145 African-American women and 177 white women who were diagnosed with breast cancer in Connecticut between January 1987 and March 1989 and were followed for survival for approximately 10 years. Cox proportional hazards models were adjusted for sociodemographic factors, biomedical factors (American Joint Committee on Cancer stage at diagnosis, histologic grade, comorbidity, obesity, menopausal status, and treatment), and lifestyle factors. RESULTS: Fully adjusted models showed that lower perceived emotional support (disagreeing with the statement, "cancer is a topic I can talk about freely with my friends/relatives") at diagnosis was associated with a higher risk of death from any cause (hazard ratio, 1.39; 95% confidence interval, 1.09-1.79). Adjustment for additional tumor characteristics (nuclear grade, estrogen and progesterone receptor status) and genetic alterations (p53, HER-2) did not alter the findings. No other psychosocial factors significantly predicted survival in patients with breast cancer. CONCLUSIONS: Higher levels of perceived emotional support showed a moderate but significant association with increased survival in African-American and white women with breast cancer who were followed for 10 years after diagnosis when adjusting for known prognostic factors. Survival was not related to coping styles, fatalism, or health locus of control.
