ABSTRACT: Objective
Despite some progress in recent years, colorectal cancer (CRC) screening adherence in the United States is still suboptimal, particularly among disadvantaged groups. In this study, we assessed the association between socioeconomic status (SES) and self-reported screening non-adherence (SNA) in a sample of racial/ethnic minorities living in San Francisco, California.Design/methods
A total of 376 participants of the San Francisco version of the Health Information National Trends Survey (SF-HINTS) with ages 50-75 years were included in this cross-sectional study. SNA was defined as not reporting blood stool test within the past year and not reporting sigmoidoscopy/colonoscopy within the past 10 years. Poisson regression models with robust variance estimators were used to evaluate the relation of SES with SNA, adjusting for measured confounders. Results are reported as prevalence ratios (PR) and 95% confidence intervals (95% CI).Results
Overall SNA was 40%. In multivariable models including all respondents, retired participants had significantly lower SNA prevalence than employed participants (PR = 0.46, 95% CI = 0.26 0.83). In stratified analyses by race/ethnicity, Black respondents with less than high school (PR = 1.93, 95% CI = 1.09, 3.43) and those with high school or equivalent (PR = 1.88, 95% CI = 1.16, 3.04) had significantly higher SNA prevalence than those with at least some college. Among non-Hispanic Asian/Pacific Islanders, those disabled had significantly higher prevalence of SNA as compared to employed people (PR = 4.26, 95% CI = 2.11, 8.60). None of the SES indicators were significantly associated to SNA among Hispanics.Conclusions
Participants with lower SES characteristics were less likely to adhere to CRC screening guidelines and being retired was a predictor of compliance. There was evidence of heterogeneity in associations between SES and CRC screening by race/ethnicity. Life circumstances of retired people could provide insights for designing interventions aimed to improve CRC screening uptake in these priority groups. Future efforts should consider mechanisms underlying differences by race/ethnicity.

Project description:IntroductionColorectal cancer screening program compliance in Turkey is around 20-30%. Factors that may affect preventive health behavior, mainly individuals' values, beliefs and attitudes, should be explored. A "Health Belief Model" (HBM) scale was developed in 1950 to explain the insufficient participation of some individuals in screening programs. The scale was adopted for colon cancer in 2002. The validity and reliability study of this scale for the Turkish language was conducted in 2007. In this study we aim to evaluate the health beliefs of relatively young individuals before the age of screening in relation to attitudes to colorectal cancer screening via the Turkish version of the scale.Materials and methodsA questionnaire composed of 14 sociodemographic questions and 33 HBM scale questions were applied to the patients of a Family Medicine outpatient clinic where the majority of the patients are relatively young people. The data was analyzed using the IBM SPSS version 21.0.ResultsA total of 310 subjects at the age of 18 and over were informed about the study. The study was completed with 215 subjects with a participation rate of 69.3%. The average age of the participants was 35.4 ± 12.8 years; 62.8% of them were women; 26.0% were students. 94.4% of the participants did not have a history of colon cancer among their first degree relatives. 58.1% agreed that "A colonoscopy should be done every ten years starting at age 50 to screen for colon cancer." Age, marital status, education and occupation status were found to have an effect on barrier scores. Young participants, singles, and those with a primary and/or secondary school education had statistically significant higher barrier scores. The motivation scores of high school graduates were higher than university graduates. The seriousness scores of men were found to be higher than women.ConclusionOur study points out that attitudes about preventive health measures are mainly associated with age, gender, education level and marital status. These personal characteristics should be taken into consideration while offering screening programs and preventive health measures to individuals in order to protect against colorectal cancer. It is better to give specific messages according to personal characteristics and specific barriers instead of general messages about conducting screening tests beginning from a young age.

Project description:Importance:Colorectal cancer (CRC) screening is rarely studied in populations who may face additional barriers to participate in cancer screening, such as African American individuals and individuals with low socioeconomic status (SES). Objective:To examine the associations of CRC screening and modalities with CRC incidence and mortality by race and SES. Design, Setting, and Participants:This cohort study used data from the Southern Community Cohort Study, which enrolled more than 85 000 participants from community health centers or stratified random sampling of the general population in 12 states in the southeastern United States. The present study included data from cohort members who were eligible for CRC screening as recommended by expert organizations based on age and family history. Participants completed questionnaires from 2002 to 2009 and were contacted again from 2008 to 2012. Linkages to state cancer registries and the National Death Index as of December 31, 2016, identified incident CRC and vital status. Data analysis was performed from January 1, 2018, to October 30, 2019. Main Outcomes and Measures:Incident CRC (n?=?632) and mortality (n?=?10?003). Cox proportional hazards regression models evaluated associations between screening modalities and CRC risk and mortality. Information on fecal occult blood test use was only obtained on the follow-up questionnaire. Self-identified race was measured as African American/black, white, or other, and SES was defined by household income. Results:This study included 47?596 participants (median baseline age, 54 years [interquartile range, 10 years]; 32 185 [67.6%] African American; 28 884 [60.7%] female; and 26 075 [54.8%] with household income <$15?000). A total of 24 432 participants (63.9%) had never undergone CRC testing at baseline. The CRC testing assessed at baseline and follow-up interviews was associated with significant CRC risk reduction (hazard ratio [HR], 0.55; 95% CI, 0.44-0.70 for ever colonoscopy at baseline). Results were similar in analyses stratified by race (African American: HR, 0.65; 95% CI, 0.50-0.85; white: HR, 0.44; 95% CI, 0.27-0.70) and household income (<$15?000: HR, 0.63; 95% CI, 0.46-0.86, ?$15?000: HR, 0.49; 95% CI, 0.35-0.69). Ever sigmoidoscopy at baseline was associated with CRC risk reduction (HR, 0.66; 95% CI, 0.51-0.87), and undergoing fecal occult blood test in the interval between baseline and follow-up interview was associated with CRC risk reduction (HR, 0.75; 95% CI, 0.57-0.98). Inverse associations were also observed between CRC mortality and receipt of colonoscopy (HR for women, 0.39; 95% CI, 0.21-0.73; HR for men, 0.69; 95% CI, 0.40-1.18) and sigmoidoscopy (HR for women, 0.37; 95% CI, 0.16-0.85; HR for men, 0.82; 95% CI, 0.46-1.47); however, the association did not extend to fecal occult blood test (HR for women, 1.02; 95% CI, 0.62-1.70; HR for men, 1.03; 95% CI, 0.55-1.93). Conclusions and Relevance:In this study, CRC test rates were low among African American individuals and those with low SES. The findings suggest that screening, particularly with colonoscopy, is significantly associated with reduced risk of CRC and mortality. The CRC disparities experienced by individuals with low SES and African American individuals may be lessened by improving access to and uptake of CRC screening.

Project description:BackgroundColorectal cancer (CRC) screening with faecal occult blood test (FOBT) has the potential to reduce the incidence and mortality of CRC. Screening uptake is known to be inferior in people with low socioeconomic position (SEP) when compared with those with high position; however, the results of most previous studies have limited value because they are based on recall or area-based measures of socioeconomic position, and might thus be subject to selective participation and misclassification. In this study we investigated differences in CRC screening participation using register-based individual information on education, employment, and income to encompass different but related aspects of socioeconomic stratification. Also, the impact of ethnicity and cohabiting status was analysed.MethodsA feasibility study on CRC screening was conducted in two Danish counties in 2005 and 2006. Screening consisted of a self-administered FOBT kit mailed to 177 114 inhabitants aged 50-74 years. Information on individual socioeconomic status was obtained from Statistics Denmark.ResultsA total of 85 374 (48%) of the invited returned the FOBT kits. Participation was significantly higher in women than in men (OR=1.58 (1.55-1.61)), when all socioeconomic and demographic variables were included in the statistical model. Participation also increased with increasing level of education, with OR=1.38 (1.33-1.43) in those with a higher education compared with short education. Also, participation increased with increasing income levels, with OR=1.94 (1.87-2.01) in the highest vs lowest quintile. Individuals with a disability pension, the unemployed and self-employed people were significantly less likely to participate (OR=0.77 (0.74-0.80), OR=0.83 (0.80-0.87), and OR=0.85 (0.81-0.89), respectively). Non-western immigrants were less likely to participate (OR=0.62 (0.59-0.66)) in a model controlling for age, sex, and county; however, this difference might be attributed to low SEP in these ethnic groups ((OR=0.93 (0.87-0.99), when adjusting for SEP indicators).ConclusionThis study based on individual information on several socioeconomic dimensions in a large, unselected population allowed for identification of several specific subgroups within the population with low CRC screening participation. Improved understanding is needed on the effect of targeted information and other strategies in order to reduce socioeconomic inequalities in screening.

Project description:Consumer-directed health plans are increasingly common, yet little is known about their impact on physician decision-making and preventive service use.To determine how patients' deductible levels and socioeconomic status may affect primary care physicians' recommendations for colorectal cancer screening.Screening recommendations were elicited using hypothetical vignettes from a national sample of 1,500 primary care physicians. Physicians were randomized to one of four vignettes describing a patient with either low or high socioeconomic status (SES) and either low- or high-deductible plan. Bivariate and multivariate analyses were used to examine how recommendations varied as a function of SES and deductible.Rates of recommendation for home fecal occult blood testing, sigmoidoscopy, colonoscopy, and inappropriate screening, defined as no screening or office-based fecal occult blood testing.A total of 528 (49%) eligible physicians responded. Overall, 7.2% of physicians recommended inappropriate screening; 3.2% of patients with high SES in low-deductible plans received inappropriate screening recommendations and 11.4% of patients with low SES in high-deductible plans for an adjusted odds ratio of 0.22 (0.05-0.89). The odds of a colonoscopy recommendation were over ten times higher (AOR 11.46, 5.26-24.94) for patients with high SES in low-deductible plans compared to patients with low SES in high-deductible plans. Funds in medical savings accounts eliminated differences in inappropriate screening recommendations.Patient SES and deductible-level affect physician recommendations for preventive care. Coverage of preventive services and funds in medical savings accounts may help to mitigate the impact of high-deductibles and SES on inappropriate recommendations.

Project description:Socioeconomic inequalities in cancer incidence are not well documented in southern Europe. We aim to study the association between socioeconomic status (SES) and colorectal, lung, and breast cancer incidence in Spain. We conducted a multilevel study using data from Spanish population-based cancer registries, including incident cases diagnosed for the period 2010-2013 in nine Spanish provinces. We used Poisson mixed-effects models, including the census tract as a random intercept, to derive cancer incidence rate ratios by SES, adjusted for age and calendar year. Male adults with the lowest SES, compared to those with the highest SES, showed weak evidence of being at increased risk of lung cancer (risk ratio (RR): 1.18, 95% CI: 0.94-1.46) but showed moderate evidence of being at reduced risk of colorectal cancer (RR: 0.84, 95% CI: 0.74-0.97). Female adults with the lowest SES, compared to those with the highest SES, showed strong evidence of lower breast cancer incidence with 24% decreased risk (RR: 0.76, 95% CI: 0.68-0.85). Among females, we did not find evidence of an association between SES and lung or colorectal cancer. The associations found between SES and cancer incidence in Spain are consistent with those obtained in other European countries.

Project description:IntroductionLow-income, low-literacy, limited English-proficient populations have low colorectal cancer (CRC) screening rates and experience poor patient-provider communication and decision-making processes around screening. The purpose of this study was to test the effect of a CRC screening decision aid on screening-related communication and decision making in primary care visits.Study designRCT with data collected from patients at baseline and immediately after the provider encounter.Setting/participantsPatients aged 50-75 years, due for CRC screening, were recruited from two safety net clinics in North Carolina and New Mexico (data collection, January 2014-September 2015; analysis, 2015).InterventionParticipants viewed a CRC screening decision aid or a food safety (control) video immediately before their provider encounter.Main outcome measuresCRC screening-related knowledge, discussion, intent, test preferences, and test ordering.ResultsThe study population (N=262) had a mean age of 58.3 years and was 66% female, 61% Latino, 17% non-Latino black, and 16% non-Latino white. Among Latino participants, 71% preferred Spanish. Compared with controls, intervention participants had greater screening-related knowledge (on average 4.6 vs 2.8 of six knowledge items correct, adjusted difference [AD]=1.8, 95% CI=1.5, 2.1) and were more likely to report screening discussion (71.0% vs 45.0%, AD=26.1%, 95% CI=14.3%, 38.0%) and high screening intent (93.1% vs 84.7%, AD=9.0%, 95% CI=2.0%, 16.0%). Intervention participants were more likely to indicate a specific screening test preference (93.1% vs 68.0%, AD=26.5%, 95% CI=17.2%, 35.8%) and to report having a test ordered (56.5% vs 32.1%, AD=25.8%, 95% CI=14.4%, 37.2%).ConclusionsViewing a CRC screening decision aid before a primary care encounter improves knowledge and shared decision making around screening in a racially, ethnically, and linguistically diverse safety net clinic population.Trial registrationThis study is registered at www.clinicaltrials.gov NCT02054598.

Project description:ObjectivesFecal blood testing is a noninvasive alternative to colonoscopy for colorectal cancer (CRC) screening and is preferred by a substantial proportion of individuals. However, participant-related determinants of the choice of screening method, particularly up-to-date screening status, remain less studied. We aimed to determine if up-to-date screening status was related to choosing a fecal blood test over colonoscopy.SettingParticipants in the population-based cross-sectional survey study Bus Santé in Geneva, Switzerland - aged 50-69 years.DesignCross-sectional survey study using mailed questionnaires inquiring about CRC screening method of choice after providing information on advantages and disadvantages of both screening methods. We used multivariable logistic regression models to determine the association between up-to-date CRC screening status and choosing fecal blood testing.Key resultsWe included 1,227 participants. Thirty-eight percent of participants did not have up-to-date CRC screening. Overall, colonoscopy (54.9%) was preferred to fecal blood testing (45.1%) (p < 0.001) as screening method of choice. However, screening method choices differed between those with (65.6% colonoscopy and 34.4% fecal blood testing) and without up-to-date CRC screening (36.5% colonoscopy and 63.5% fecal blood testing). Not having up-to-date CRC screening was associated with a higher probability of choosing fecal blood testing as screening method (odds ratio = 2.6 [1.9; 3.7], p < 0.001) after adjustment for the aforementioned confounders.ConclusionsNot having up-to-date screening was independently associated with fecal blood testing as the preferred method for CRC screening. Proposing this method to this subpopulation, in a context of shared decision, could potentially increase screening uptake in settings where it is already high.

Project description:BACKGROUND:A growing body of research has demonstrated that individuals who live in neighborhoods with more severe socioeconomic deprivation may have higher risks for colorectal cancer (CRC). However, previous studies have examined neighborhood socioeconomic status (SES) at only 1 point in time, and it is unclear whether changes in neighborhood SES also can influence the risks of CRC. METHODS:Cox regression analysis was used to examine different trajectories of change in neighborhood SES over 10 years in relation to the incidence of CRC among 266,804 participants (ages 51-70 years) in the National Institutes of Health-AARP Diet and Health Study. Eligible participants reported living in the same neighborhood at baseline (1995-1996) and from 2004 to 2006 according to a follow-up questionnaire. Changes in neighborhood SES were measured between 1990 and 2000 by SES indices derived from Census data. Neighborhoods were grouped into 4 categories based on median SES indices in 1990 and 2000 (low-low, low-high, high-low, and high-high). RESULTS:Compared with residents whose neighborhoods were in the higher SES group at both time points (reference category), those whose neighborhoods were consistently in the low SES group had a 7% higher risk of developing CRC (hazard ratio, 1.07; 95% confidence interval, 1.00-1.14). Moreover, the risk of CRC was 15% higher (hazard ratio, 1.15; 95% confidence interval, 1.02-1.28) for those living in neighborhoods with decreasing SES (high-low) over time. CONCLUSIONS:The current findings suggest that exposure to consistently low SES neighborhoods and/or a decrease in neighborhood SES over a period of time may be associated with higher risks of CRC.

Project description:Population screening for colorectal cancer (CRC) has recently commenced in the United Kingdom supported by the evidence of a number of randomised trials and pilot studies. Certain factors are known to influence screening cost-effectiveness (e.g. compliance), but it remains unclear whether an ageing population (i.e. demographic change) might also have an effect. The aim of this study was to simulate a population-based screening setting using a Markov model and assess the effect of increasing life expectancy on CRC screening cost-effectiveness. A Markov model was constructed that aimed, using a cohort simulation, to estimate the cost-effectiveness of CRC screening in an England and Wales population for two timescales: 2003 (early cohort) and 2033 (late cohort). Four model outcomes were calculated; screened and non-screened cohorts in 2003 and 2033. The screened cohort of men and women aged 60 years were offered biennial unhydrated faecal occult blood testing until the age of 69 years. Life expectancy was assumed to increase by 2.5 years per decade. There were 407 552 fewer people entering the model in the 2033 model due to a lower birth cohort, and population screening saw 30 345 fewer CRC-related deaths over the 50 years of the model. Screening the 2033 cohort cost pound 96 million with cost savings of pound 43 million in terms of detection and treatment and pound 28 million in palliative care costs. After 30 years of follow-up, the cost per life year saved was pound 1544. An identical screening programme in an early cohort (2003) saw a cost per life year saved of pound 1651. Population screening for CRC is costly but enables cost savings in certain areas and a considerable reduction in mortality from CRC. This Markov simulation suggests that the cost-effectiveness of population screening for CRC in the United Kingdom may actually be improved by rising life expectancies.

Project description:PURPOSE:This study aimed to investigate inequalities in colorectal cancer (CRC) screening rates in Korea and trends therein using the slope index of inequality (SII) and relative index of inequality (RII) across income and education groups. MATERIALS AND METHODS:Data from the Korean National Cancer Screening Survey, an annually conducted, nationwide cross-sectional survey, were utilized. A total of 17174 men and women aged 50 to 74 years were included for analysis. Prior experience with CRC screening was defined as having either a fecal occult blood test within the past year or a lifetime colonoscopy. CRC screening rates and annual percentage changes (APCs) were evaluated. Then, SII and RII were calculated to assess inequality in CRC screening for each survey year. RESULTS:CRC screening rates increased from 23.4% in 2005 to 50.9% in 2015 (APC, 7.8%; 95% CI, 6.0 to 9.6). Upward trends in CRC screening rates were observed for all age, education, and household income groups. Education inequalities were noted in 2009, 2014, and overall pooled estimates in both indices. Income inequalities were inconsistent among survey years, and overall estimates did not reach statistical significance. CONCLUSION:Education inequalities in CRC screening among men and women aged 50 to 74 years were observed in Korea. No apparent pattern, however, was found for income inequalities. Further studies are needed to thoroughly outline socio-economic inequalities in CRC screening.
