Colorectal Cancer Screening Adherence in Selected Disabilities Over 10 Years.

Colorectal cancer (CRC) is the second leading cause of cancer mortality in the U.S.; however, if the population aged 50 years or older received routine screening, approximately 60% of these deaths could be eliminated. This study investigates whether adults, aged 50-75 years, with one of three disabilities (blind/low vision [BLV], intellectual disability [ID], spinal cord injury [SCI]) receive CRC screening at rates equivalent to adults without the three disabilities, by accounting for combinations of recommended CRC screenings during a 10-year period (colonoscopy, sigmoidoscopy, fecal occult blood test). South Carolina Medicaid and Medicare, State Health Plan, and hospital discharge data (2000-2009) were analyzed (2013-2015) to estimate the proportion of adherence to and adjusted odds of CRC screening over time among adults with one of the three disabilities, BLV, ID, or SCI, versus adults without these conditions. The estimated proportion of adults who adhere to changing recommendations over time was lower for adults with ID (34.32%) or SCI (44.14%) compared with those without these disabilities (48.48%). All three case groups had significantly lower AORs of adherence versus those without (BLV: AOR=0.88, 95% CI=0.80, 0.96; ID: AOR=0.55, 95% CI=0.52, 0.59; SCI: AOR=0.88, 95% CI=0.82, 0.95). In this study, adults with BLV, ID, or SCI were less likely to receive and adhere to CRC screening recommendations than those without these disabilities. This method provides a thorough evaluation of adherence to CRC screening by considering levels of adherence during each month of Medicaid or Medicare coverage.

Improving Breast Cancer Screening Adherence Among Hospitalized Women.

More than a third of hospitalized women are both overdue for breast cancer screening and at high risk for developing breast cancer. The purpose of the study was to evaluate if inpatient breast cancer screening education, scheduling an outpatient mammography appointment before hospital discharge at patients' convenience, phone call reminders, and a small monetary incentive ($10) would result in improved adherence with breast cancer screening for these patients. A prospective intervention pilot study was conducted among 30 nonadherent women aged 50-75 years hospitalized to a general medicine service. Sociodemographic, reproductive history, family history for breast cancer, and medical comorbidity data were collected for all patients. Chi-square and unpaired t-tests were utilized to compare characteristics among women who did and did not get a screening mammogram at their prearranged appointments. Of the 30 women enrolled who were nonadherent to breast cancer screening, the mean age for the study population was 57.8 years (SD = 6), mean 5-year Gail risk score was 1.68 (SD = 0.67), and 57% of women were African American. Only one-third of the enrolled women (n = 10) went to their prearranged appointments for screening mammography. Not feeling well enough after the hospitalization and not having insurance were reported as main reasons for missing the appointments. Convenience of having an appointment scheduled was reported to be a facilitator of completing the screening test. This intervention was partially successful in enhancing breast cancer screening among hospitalized women who were overdue and at high risk. Future studies may need to evaluate the feasibility of inpatient screening mammography to improve adherence and overcome the significant barriers to compliance with screening.

Abstract B70: Exploring the role of acculturation in breast, colorectal and cervical cancer screening among Hispanic women

Abstract Racial and ethnic disparities exist in cancer screening and management among Hispanics. Although cancer poses a burden among Hispanic women compared to non-Hispanic white women (nHw), screening rates for breast, colorectal and cervical cancer in Hispanic women lag behind nHw. The Hispanic population is heterogeneous and comprises individuals with diverse heritages. Furthermore, considerable variations in health outcomes and practices have been observed across Hispanic subgroups, supporting the relevance of studying each subgroup separately. Since early detection can reduce the burden of cancer, it is important to identify factors that can predict cancer screening within subgroups of Hispanic women. We sought to assess the role of acculturation in adherence to recommended cancer screening practices among Hispanic postmenopausal women, and to assess whether this association varies by Hispanic subgroup using data from the Women's Health Initiative. We included women who identified themselves as Hispanic in the baseline questionnaire (N=3, 263). All women who reported a personal history of cancer other than non-melanoma skin cancer were excluded from the study. Only women without a hysterectomy were included in the cervical cancer screening analysis (N=1,754). Acculturation was measured using self-reported country of birth, language preference and length of residency in the United States (US). Cancer screening adherence was assessed based on the American Cancer Society guidelines in place at the beginning of the study in 1993. The study outcomes were self-reported breast cancer screening (mammography use) and cervical cancer screening (Pap smear use) during the past year and colorectal cancer screening (sigmoidoscopy or colonoscopy use) within five years prior to the interview. Logistic regression was used to estimate the prevalence odds ratio for three types of cancer screening (breast, cervical and colorectal) according to the acculturation level among Hispanic women and within subgroups (Cuban (N=137), Mexican (N=1,151), Puerto Rican (N=289) and Other Hispanic (N=693)), with adjustment for age, alcohol use, family history of cancer, body mass index, physical activity level, and smoking status. Prevalence of breast, colorectal and cervical cancer screening was 68.7%, 55.9% and 47.1%, respectively. Highly acculturated women (US-born, English language preference and living in the US longer than in their country of origin) were more likely to be screened for breast (OR=2.12; 95% CI: 1.57-2.86), cervical (OR=1.46; 95% CI: 0.98-2.18) and colorectal cancer (OR=4.61; 95% CI: 3.27-6.50) within guidelines compared to Hispanic women with low acculturation level. Adjusting for socioeconomic factors attenuated the strength of these associations. For receipt of mammogram, subgroup analysis showed that acculturation mattered in the receipt of a mammogram only for Mexican/Mexican American women (OR=1.35; 95% CI: 1.01-1.82) for high vs. moderate/low acculturation. High acculturation was associated with greater adjusted odds of colorectal cancer screening among Mexican/Mexican American (OR=1.46; 95% CI: 1.10-1.95), Cuban women (OR=18.17; 95% CI: 2.17-152.37), and women from other Hispanic origins (OR=1.50; 95% CI: 1.07-2.11) when compared to women from their same national origin with a moderate/low acculturation level. No significant association between acculturation and cervical cancer screening were observed within the subgroups. These data show important differences in the impact of acculturation on cancer screening uptake among subgroups of Hispanic women. These findings will be useful to develop educational programs, and culturally tailored strategies for each Hispanic subgroup with the end goal of reducing the observed racial and ethnic disparities existent in cancer and promoting colorectal and breast cancer screening.

Abstract A42: Breast and cervical cancer screening adherence among Latina women living in South Texas: Results from the Esperanza y Vida (Hope and Life) intervention

Abstract PURPOSE The evidence-based Esperanza y Vida [EyV] (Hope and Life) program was developed to increase awareness of screening methods among Latinas living in South Texas and explore social and contextual influences that may contribute to disproportionate breast cancer (BC) and high cervical cancer (CC) incidence. This study aimed to identify sociodemographic characteristics of participants, including religion and church attendance, within the larger EyV study, who reported barriers to BC and CC screening. METHODS Lay health advisors were trained to deliver the program to promote BC and CC awareness and screening. Participants (N=227) completed questionnaires that assessed knowledge, screening adherence: breast self-exam [BSE], clinical breast exam [CBE], mammography, Papanicolaou (pap) test, and health beliefs about BC and CC and were contacted for follow-up to assess screening and offer assistance in obtaining exams. RESULTS There was no association among Latinas who participated in BSE (N=118, chi-squared=8.978, p=.344), CBE (N=119, chi-squared=1.875, p=.392), and mammogram (N=98, chi-squared=8.978, p=.344) in the past 12-months and church attendance. Latinas that received a pelvic exam (N=109) and pap test (N=139) did so as part of their yearly exam. The most prevalent barriers (N=62) to screening adherence were cost (N=45) and lack of adequate health insurance (N=44). Eligible Latinas (N=174) that reported barriers to breast exams in the past 12-months believed 1) healthcare professionals felt neutral (p=.099) and 2) their friends not interested (p=.055) in screening Hispanic/Latinas for BC and CC, 3) weekly church attendance (p=.071) and 4) no education (p=.097). Eligible Latinas (N=175) that reported barriers to pap testing in the past 12-months believed 1) healthcare professionals felt not interested (p=.248) and 2) their friends either not interested (p=.092) or neutral (p=.126) in screening Hispanic/Latinas for BC and CC, 3) weekly church attendance (p=.161) and 4) age (p=.014) were factors. CONCLUSIONS These findings have implications for further culturally-tailored BC and CC education, screening interventions and patient navigation. Additional exploration of the influence of healthcare professionals and social networks in screening behaviors among this population is warranted. Citation Format: Jameisha B. Brown, Thelma C.

Spatial and temporal variations of screening for breast and colorectal cancer in the United States, 2008 to 2012.

Cancer screening tests are important tools to combat cancer-related morbidity and mortality. There is limited up-to-date research on spatial and temporal variations of colorectal and breast cancer screening in the United States.County-level data of cancer screening adherence rates were generated from 2008 to 2012 Behavioral Risk Factor Surveillance System. We performed the univariate local indicators for spatial analyses (LISA) for the geographic differences of screening adherence rate and the differential LISA for the change of screening adherence rate from 2008 to 2012.In the univariate LISA, low-to-low clusters were consistently identified in counties of New Mexico, Wyoming, and Mississippi (P < 0.05) for both screenings. In the differential LISA, we found low-to-low clusters in Indiana counties (P < 0.05) for mammography screening, which implied that counties with a below-average difference in mammography adherence were surrounded by counties of below-average difference in adherence rates. A high-to-high cluster was also identified in the southern Appalachian counties for mammography screening (P < 0.05). No obvious spatial pattern was found for the colorectal cancer screening adherence rate across the United States.We found low-to-low clusters over time in adherence to screening guidelines for both cancer types in New Mexico, Wyoming, and Mississippi, and clusters of potential decrease in adherence to mammography screening guideline in counties of Indiana. The study also showed improvement on mammography screening clustered in southern Appalachia. The methodology adopted in this study identified areas with clusters of consistent low adherence to screening and a decrease in adherence, which implies that further research and intervention is warranted.

Mental Illness Is Not Associated with Adherence to Colorectal Cancer Screening: Results from the California Health Interview Survey.

Colorectal cancer is the second leading cause of cancer-specific death in the USA. Evidence suggests people with mental illness are less likely to receive preventive health services, including cancer screening. We hypothesized that mental illness is a risk factor for non-adherence to colorectal cancer-screening guidelines. We analyzed results of the 2007 California Health Interview Survey to test whether mental illness is a risk factor for non-adherence to colorectal cancer-screening recommendations among individuals age 50 or older (N=15,535). This cross-sectional dataset is representative of California. Screening was defined as either fecal occult blood testing during the preceding year, sigmoidoscopy, or colonoscopy during the preceding 5years. Mental illness was identified using the Kessler K6 screening tool. Associations were evaluated using weighted multivariate logistic regressions. Mental illness was not associated with colorectal cancer-screening adherence (OR 0.89; 95% CI 0.63-1.25). Risk factors for non-adherence included being female (OR 1.25; 95% CI 1.09-1.44), delaying accessing health care during the previous year (OR 1.89; 95% CI 1.56-2.29). Unlike previous studies, this study did not find a relationship between mental illness and colorectal cancer-screening adherence. This could be due to differences in study populations. State-specific healthcare policies involving care coordination for individuals with mental illness could also influence colorectal cancer-screening adherence in California.

Human papillomavirus vaccination and subsequent cervical cancer screening in a large integrated healthcare system

Human papillomavirus vaccination may result in lowered intention to be screened for cervical cancer, potentially leading to gaps in screening coverage and avoidable cervical cancer diagnoses. The purpose of this study was to examine the association between human papillomavirus vaccination and subsequent cervical cancer screening initiation and adherence to recommended screening intervals to detect gaps in screening coverage and inform future prevention efforts. A retrospective cohort study was conducted in 2 distinct cohorts of female members of Kaiser Permanente Southern California, which is a large integrated healthcare delivery system. Papanicolaou screening initiation was evaluated in women who reached 21 years from 2010-2013. Adherence to recommended screening intervals was evaluated in women who were 25-30 years old in 2010. All women were observed to the end of 2013 for the evaluation of their screening behaviors. History of human papillomavirus vaccination and Papanicolaou screening were obtained from electronic medical records. Adherence to recommended screening intervals was measured as ≥85% vs <85% of the observed "screening up-to-date" person-time. Multivariable Cox and logistic regression models were used to examine associations between vaccination history and screening initiation and interval adherence. Demographic characteristics, gynecologic health history, healthcare use, and characteristics of women's primary care providers were included as potential confounders in the analyses. There were 27,352 and 41,328 women included in the screening initiation and screening interval adherence analyses, respectively. In comparison with unvaccinated women, adjusted hazard ratios (95% confidence intervals [CIs]) for screening initiation among women who had been vaccinated against human papillomavirus were 1.19 (95%CI, 1.11-1.28), 1.44 (95% CI, 1.34-1.53), and 1.57 (95% CI, 1.50-1.65) for 1, 2, and ≥3 doses, respectively. Adjusted odds ratios for screening interval adherence were 0.93 (95% CI, 0.83-1.04), 1.73 (95%CI, 1.52-1.97), and 2.29 (95% CI, 2.05-2.56), for 1, 2, and ≥3 doses, respectively. Women who had been vaccinated against human papillomavirus in this community-based, integrated healthcare setting were more likely to be screened for cervical cancer than were unvaccinated women. Our findings underscore the need for targeted interventions among unvaccinated women who may be disproportionally affected by cervical cancer, despite the presence of population-based screening programs.

Overuse of colorectal cancer screening services in the United States and its implications.

As a standard way for prevention and early detection of colorectal cancer (CRC), colonoscopy has been used for CRC screening in the United States for more than one decade. An article entitled “Assessing Colorectal Cancer Screening Adherence of Medicare Fee-For-Service Beneficiaries Age 76 to 95 Years” recently published at the Journal of Oncology Practice reports the trends in overuse of CRC screening services among average-risk elderly populations at the age of 76–95 years. Several reasons for overusing colonoscopy have been postulated, and some strategies for reducing overuse of CRC screening services have also been proposed.

Intrastate Variations in Rural Cancer Risk and Incidence: An Illinois Case Study.

Although rural-urban cancer disparities have been explored with some depth, disparities within seemingly homogeneous rural areas have received limited attention. However, exploration of intrarural cancer incidence may have important public health implications for risk assessment, cancer control, and resource allocation. The objective of this study was to explore intrastate rural cancer risk and incidence differences within Illinois. Illinois's 83 rural counties were categorized into northern, central, and southern regions (IL-N, IL-C, and IL-S, respectively). Chi-square test for independence and analysis of variance calculations were performed to assess regional differences in demographic characteristics, socioeconomic deprivation, smoking history, obesity, cancer-screening adherence, and density of general practitioners. Age-adjusted incidence rates were calculated for 5 cancer categories: all cancers combined, lung, colorectal, breast (female), and prostate cancers. Unadjusted and adjusted incidence rate ratios (IRRs) were calculated to evaluate regional differences in rates for each cancer category. Socioeconomic deprivation varied by region: 4.5%, 6.9%, and 40.6% of IL-N, IL-C, and IL-S counties, respectively (P < .001). Smoking history also significantly differed by region. Mean former/current smoking prevalence in IL-N, IL-C, and IL-S counties was 46.4%, 48.2%, and 51.4%, respectively (P = .006). In unadjusted analysis, IL-C (IRR = 1.12; 95% confidence interval [CI], 1.02-1.23) and IL-S (IRR = 1.24; 95% CI, 1.13-1.35) had increased lung cancer incidence compared with IL-N. Elevated risk remained in IL-S after adjusting for relevant factors such as smoking and socioeconomic deprivation (IRR = 1.14; 95% CI, 1.04-1.26). Socioeconomic deprivation, health behaviors, and lung cancer incidence varied across rural regions. Our findings underscore the importance of identifying cancer risk heterogeneity, even within a state, to effectively target risk factor reduction and cancer control interventions.

Effect of reminders mailed to general practitioners on colorectal cancer screening adherence: a cluster-randomized trial

Reminders have been used in various settings, but failed to produce convincing evidence of benefits on patient adherence to colorectal cancer (CRC) screening. The aim of this study was to assess the effectiveness of sending general practitioners (GPs) printed reminders about CRC screening. We conducted a cluster-randomized controlled trial involving 144 GPs in the Val-de-Marne district (France), who provided care for any reason to 20 778 patients eligible for CRC screening between June 2010 and November 2011. Data were collected from the main statutory health-insurance programme and local cancer screening agency. GPs were randomly assigned in a 1 : 1 proportion to the intervention or the control group. Every 4 months, intervention-group GPs received a computer-generated printed list of patients who had not performed scheduled faecal occult blood test (FOBT) screening. The primary outcome was patient adherence to FOBT screening or exclusion from CRC screening for medical reasons. The screening adherence rate was 31.2% [95% confidence interval (CI) 30.3-32.1] in the control group and 32.9% (95% CI 32.0-33.8) in the intervention group [crude relative risk, 1.05 (95% CI 1.01-1.09), P<0.01]. This rate was not significantly different between groups by multilevel modelling accounting for clustering and confounding variables [adjusted relative risk, 1.07 (95% CI 0.95-1.20), P=0.27]. Computer-generated printed reminders sent to GPs did not significantly improve patient adherence to organized CRC screening by the FOBT.

Multistate transitional models for measuring adherence to breast cancer screening: A population-based longitudinal cohort study with over two million women.

Objective Prior work on the disparities among women in breast cancer screening adherence has been methodologically limited. This longitudinal study determines and examines the factors associated with becoming adherent. Methods In a cohort of Canadian women aged 50-74, a three-state transitional model was used to examine adherence to screening for breast cancer. The proportion of time spent being non-adherent with screening was calculated for each woman during her observation window. Using age as the time scale, a relative rate multivariable regression was implemented under the three-state transitional model, to examine the association between covariates (all time-varying) and the rate of becoming adherent. Results The cohort consisted of 2,537,960 women with a median follow-up of 8.46 years. Nearly 31% of women were continually up-to-date with breast screening. Once a woman was non-adherent, the rate of becoming adherent was higher among longer term residents (relative rate = 1.289, 95% confidence interval 1.275-1.302), those from wealthier neighbourhoods, and those who had an identifiable primary care provider who was female or had graduated in Canada. Conclusion Individual and physician-level characteristics play an important role in a woman's adherence to screening. This work improves the quality of evidence regarding disparities among women in adherence to breast cancer screening and provides a novel methodological foundation to investigate adherence for other types of screening, including cervix and colorectal cancer screening.

Assessing Colorectal Cancer Screening Adherence of Medicare Fee-for-Service Beneficiaries Age 76 to 95 Years.

There are concerns about potential overuse of colorectal cancer (CRC) screening services among average-risk individuals older than age 75 years. Using a 5% random noncancer sample of Medicare beneficiaries who resided in the SEER areas, we examined rates of CRC screening adherence, defined by the Medicare coverage policy, among average-risk fee-for-service beneficiaries age 76 to 95 years from 2002 to 2010. The two outcomes are the status of overall CRC screening adherence, and the status of adherence to colonoscopy (v other modalities) conditional on patient adherence. Overall CRC screening adherence rates of Medicare beneficiaries age 76 to 95 years increased from 13.0% to 21.4% from 2002 to 2010. In 2002, 2.2% of beneficiaries were adherent to colonoscopy, and 10.7%, by other modalities; the corresponding rates were 19.5% and 1.9%, respectively, in 2010. Specifically, rates of adherence to colonoscopy were 1.1% for those age 86 to 90 years and almost nil for those age 91 to 95 years in 2002, but the rates became 13.5% and 8.2%, respectively, in 2010. Compared with white beneficiaries, black beneficiaries age 76 to 95 years had a 7-percentage-point lower adherence rate. However, overall adherence rates among blacks increased by 168.6% from 2002 to 2010, whereas rates among whites increased by 63.0%. Logistic regressions showed that blacks age 86 to 95 years were less likely than whites to be adherent (odds ratio, 0.56; 95% CI, 0.47 to 0.59) but were more likely to be adherent to colonoscopy (odds ratio, 2.34; 95% CI, 1.47 to 3.91). High proportions of average-risk Medicare fee-for-service beneficiaries screened by colonoscopy may represent opportunities for improving appropriateness and allocative efficiency of CRC screening by Medicare.

Effect of a Financial Incentive for Colorectal Cancer Screening Adherence on the Appropriateness of Colonoscopy Orders.

Performance incentives for preventive care may encourage inappropriate testing, such as cancer screening for patients with short life expectancies. Defining screening colonoscopies for patients with a >50% 4-year mortality risk as inappropriate, the authors performed a pre-post analysis assessing the effect of introducing a cancer screening incentive on the proportion of screening colonoscopy orders that were inappropriate. Among 2078 orders placed by 23 attending physicians in 4 academic general internal medicine practices, only 0.6% (n = 6/1057) of screening colonoscopy orders in the preintervention period and 0.6% (n = 6/1021) of screening colonoscopy orders in the postintervention period were deemed "inappropriate." This study found no evidence that the incentive led to an increase in inappropriate screening colonoscopy orders.

Adherence to cancer screening guidelines in Australian survivors of allogeneic blood and marrow transplantation (BMT).

Allogeneic Blood and Marrow Transplant (BMT) survivors are at high risk of secondary cancers. Although current guidelines endorse survivors following Country‐specific general population screening recommendations to mitigate this risk, little is known about cancer screening adherence in Australian BMT survivors. We conducted a cross‐sectional survey of 441 BMT survivors who were >1 year post transplant, to explore rates of screening for secondary cancers and to identify barriers to cancer screening recommendations. Survey instruments included the Sydney Post‐BMT Survey, FACT‐BMT, DASS 21, The Chronic Graft versus Host Disease (GVHD) Activity Assessment–Patient Self‐Report (Form B), the Lee Chronic GVHD Symptom Scale, Fear of Cancer Recurrence Scale, and The Post Traumatic Growth Inventory. Fifty‐seven percent of respondents were male, median age 54 years, and 40% were >6 years post‐BMT. Rates of cancer screening adherence were as follows: cervical 63.4%, breast 53.3%, skin 52.4%, and bowel 32.3%. Older BMT survivors and those >2 years post transplant were more likely to undergo cancer screening. Improved quality of life was associated with screening for skin, breast, and cervical cancer. Fear of cancer recurrence negatively impacted on cervical screening. For those who had not undergone screening, the majority reported not being advised to do so by their treatment team. This study is the largest and most comprehensive to date exploring cancer screening adherence in BMT survivors in Australia. These data provide the basis for health service reform to better meet the needs of BMT survivors and provide evidence to support counseling and education of both patients and professionals.

Comparative effectiveness of two outreach strategies for cervical cancer screening

ObjectiveTest-specific reminder letters can improve cancer screening adherence. Little is known about the effectiveness of a reminder system that targets the whole person by including multiple screening recommendations per letter. MethodsWe compared the effectiveness of a Pap-specific reminder letter sent 27months after a woman's last Pap, to a reminder letter that included up to seven preventive service recommendations sent before a woman's birthday (“birthday letter”) on Pap smear adherence from a natural experiment occurring in routine clinical care. Participants included 82,016 women from Washington State who received 72,615 Pap-specific letters between 2003 and 2007 and 100,218 birthday letters between 2009 and 2012. We defined adherence as having a Pap test within a six month window around the Pap test due date. Using logistic regression, we calculated adjusted odds ratios (OR) for adherence with 95% confidence intervals (CI) following the birthday letter with 1–2 recommendations, 3–5 recommendations, and 6–7 recommendations compared to the Pap-specific letter. All analyses were stratified by whether a woman was up-to-date or overdue for screening at the time she received a letter. ResultsAdjusted ORs showed reduced adherence following the birthday letter compared with the Pap-specific letter for up-to-date women whether the letter had 1–2 recommendations (OR=0.37, 95%CI=0.36–0.39), 3–5 recommendations (OR=0.44, 95%CI=0.42–0.45), or 6–7 recommendations (OR=0.36, 95%CI=0.32–0.40). We noted no difference in Pap-test adherence between letter types for overdue women. ConclusionsIn conclusion, for women regularly adherent to screening, an annual birthday letter containing reminders for multiple preventive services was less effective at promoting cervical cancer screening compared with a Pap-specific letter.

Factors Associated with Adherence to Colorectal Cancer Screening among Moderate Risk Individuals in Iran.

Colorectal cancer is one of the most common neoplasms in Iran. Secondary prevention (colorectal cancer screening) is important and a most valuable method of early diagnosis of this cancer. The objectives of this study were to determine the factors associated with colorectal cancer screening adherence among Iranians 50 years and older using the Health Belief Model. This cross-sectional study was conducted from June 2012 to May 2013. A convenience sample of 200 individuals aged 50 and older was recruited from the population at outpatient clinics in teaching hospitals. Data gathering tools were the Champions health belief model scale (CHBMS) with coverage of socio-demographic background and CRC screening information. Multiple logistic regression was performed to identify factors associated with colorectal cancer screening adherence. The mean age of participants was 62.5± 10.8 and 75.5% were women. A high percentage of the participants had not heard or read about colorectal cancer (86.5%) and CRC screening (93.5%). Perceived susceptibility to colorectal cancer had the lowest percentage of all of the subscales. Participants who perceived more susceptibility (OR =2.99; CI 95%: 1.23-5.45) and reported higher knowledge (OR =1.29; CI 95%: 1.86-3.40) and those who reported fewer barriers (OR =.37; CI 95%:.21- .89), were more likely to have carried out colorectal cancer screening. Our findings indicated that CRC knowledge, perceived susceptibility and barriers were significant predictors of colorectal cancer screening adherence. Strategies to increase knowledge and overcome barriers in risk individuals appear necessary. Education programs should be promoted to overcome knowledge deficiency and negative perceptions in elderly Iranians.

Examining Social Capital and Its Relation to Breast and Cervical Cancer Screening among Underserved Latinas in the U.S.

Many Latinos in the U.S. experience structural barriers to health care. Social capital and its implications for health and access to health care among this group are not well understood by researchers. This study examined associations between social capital and breast and cervical cancer screening adherence among a sample of 394 predominately Puerto Rican and Dominican women. Data were collected at baseline from Latinas attending screening education programs in Buffalo, New York and New York City in 2011-2012. Social capital was higher among Latinas who were older, better educated, insured, and spoke English. In multivariable logistic regression, a one unit increase in social capital index score was associated with greater adherence to Pap test (OR = 1.61), clinical breast exam (OR = 1.47) and mammography screening (OR = 1.50). Social capital should be further explored as a strategy to facilitate breast and cervical cancer screening among underserved Latinas.

Predictors of Non-Adherence to Breast Cancer Screening among Hospitalized Women.

ObjectiveDisparities in screening mammography use persists among low income women, even those who are insured, despite the proven mortality benefit. A recent study reported that more than a third of hospitalized women were non-adherent with breast cancer screening. The current study explores prevalence of socio-demographic and clinical variables associated with non-adherence to screening mammography recommendations among hospitalized women.Patients and MethodsA cross sectional bedside survey was conducted to collect socio-demographic and clinical comorbidity data thought to effect breast cancer screening adherence of hospitalized women aged 50–75 years. Logistic regression models were used to assess the association between these factors and non-adherence to screening mammography.ResultsOf 250 enrolled women, 61% were of low income, and 42% reported non-adherence to screening guidelines. After adjustment for socio-demographic and clinical predictors, three variables were found to be independently associated with non-adherence to breast cancer screening: low income (OR = 3.81, 95%CI; 1.84–7.89), current or ex-smoker (OR = 2.29, 95%CI; 1.12–4.67), and history of stroke (OR = 2.83, 95%CI; 1.21–6.60). By contrast, hospitalized women with diabetes were more likely to be compliant with breast cancer screening (OR = 2.70, 95%CI 1.35–5.34).ConclusionBecause hospitalization creates the scenario wherein patients are in close proximity to healthcare resources, at a time when they may be reflecting upon their health status, strategies could be employed to counsel, educate, and motivate these patients towards health maintenance. Capitalizing on this opportunity would involve offering screening during hospitalization for those who are overdue, particularly for those who are at higher risk of disease.

Abstract B73: Do generational cohort differences in social networks influence persistent and sporadic screeners' perceptions of breast cancer screening?

Abstract Purpose: Low breast cancer screening participation and adherence to guidelines is problematic. Our prior work found that on average 18% of women from four tribes adhered to Indian Health Service (IHS) mammographic screening guidelines over five years (study funded by Native American Research Centers for Health (NARCH IV). We sought to identify how adherent (persistent) and non-adherent (sporadic) screeners may differ by demographic and theoretical mediators that have successfully guided interventions in other health disparities populations. As part of planning interventions to increase AI/AN women's persistent screening, we characterized differences in persistent and sporadic screeners' responses to Social Norms and Health Beliefs in the context of social networks. Methods: From 2013-2014, we interviewed 55 recruited women (41 sporadic screeners and 14 persistent screeners) who had been randomly assigned unique identifiers. Data from interviews included demographic characteristics, assessments of health literacy, and social relationships from theoretical perspectives of: Theory of Planned Behavior, Social Support, Social Norms, Health Beliefs, and Social Networks. In this study, we examined areas that distinguished persistent from sporadic screeners—social norms and health beliefs--and we conceptualized the make-up of screeners' social networks to consider members by their generational status relative to the screener. We coded and categorized data; Fisher's Exact Test and Kruskal-Wallis Test were applied as appropriate. Results: We identified three mediators with four significant differences. 1. Social Norms: (A) Persistent screeners were significantly more likely to believe reservation women favored getting an annual mammogram while sporadic screeners were more likely to believe women were against getting annual mammograms (P = 0.03). Responses are consistent with Social Norms theory, but screeners' beliefs about friends' screening participation appear less consistent with the theory. (B) Persistent screeners by a large proportion believed friends obtained fewer mammograms than themselves while sporadic screeners had no prevailing view (P = 0.02). 2. Health Beliefs (susceptibility to breast cancer): (C) While sporadic screeners expressed considerable uncertainty about their susceptibility, persistent screeners expressed no uncertainty (P = 0.02). 3. Social Networks: (D) Examination of the generational membership of screeners' Social Networks showed that sporadic screeners' networks had significantly more members from generations younger than themselves compared to persistent screeners' networks ( P = 0.01). Conclusions: Screeners with younger social networks may in part be influenced to be sporadic screeners because they do not benefit from exposure to more mature and experienced individuals in their social networks. The excess of younger generation members in sporadic screeners' networks may expose them generally to people who do not screen (or have limited screening experience) due to age. This exposure would confirm for them that reservation women generally do not favor screening and would explain their mixed view of friends' screening behavior. The younger membership of sporadic screeners' networks also may explain why this group would express substantial uncertainty about their own susceptibility to breast cancer relative to other women. If the network is not of an age where breast cancer and screening are pertinent topics, screeners may not have a knowledgebase (accurate or not) from which to build their views. We anticipate further testing to ascertain the role of social networks in the views and behaviors of sporadic and persistent screeners before considering any interventions.

Deliberative and intuitive risk perceptions as predictors of colorectal cancer screening over time.

Cancer risk perceptions may involve intuitions-including both affect as well as gut-level thoughts about risk-and deliberative risk magnitudes. Yet, little research has examined the potentially diverse relations between risk perceptions and behavior across time. A highly diverse primary care sample (N=544, aged ≥50) was utilized to compare how deliberative and intuitive perceptions of risk relate to chart-confirmed colorectal cancer screening at cross-sectional and prospective time points. At baseline, deliberative and intuitive risk perceptions were negatively associated with chart-confirmed colorectal cancer screening adherence in bivariable but not multivariable analyses. Among those who were non-adherent with colorectal cancer screening at baseline, deliberative and intuitive risk perceptions were positively associated with prospective uptake of chart-confirmed colorectal cancer screening adherence at 12-months in bivariable analyses; only deliberative risk perceptions remained significant in the multivariable model. This study indicates that diverse risk perceptions are differentially important for screening at different time points.
