Familial risk and colorectal cancer screening health beliefs and attitudes in an insured population

OBJECTIVE: To examine the relationship between health beliefs and attitudes toward colorectal cancer screening, strength of family history risk, and being appropriately screened for colorectal cancer. METHODS: In February 2004, 7000 randomly selected members of a multi-specialty group practice located in Boston, MA were mailed a brief survey that was used to ascertain colorectal cancer family history. A follow-up survey that contained questions representing selected constructs of the Health Belief Model, Theory of Planned Behavior, and healthcare experiences was then mailed to all 355 individuals who reported a family history in the initial survey and 710 randomly selected participants with no colorectal cancer family history. RESULTS: Participants who were appropriately screened had higher mean scores for perceived cancer risk, subjective norms, and perceived benefits and lower scores for perceived barriers. Multivariate findings indicate that having high perceptions of risk for colorectal cancer was a significant correlate of being screened appropriately among individuals with a strong family history. CONCLUSIONS: For those at greatest colorectal cancer risk due to family history, ensuring that these individuals understand their personal risk might lead to increased colorectal cancer screening participation. Future intervention research is warranted to examine if raising perceptions of risk can increase screening behaviors in individuals with colorectal cancer risk due to family history.     

Are people being screened for colorectal cancer as recommended? Results from the National Health Interview Survey

BACKGROUND: The evidence is now compelling that colorectal cancer incidence and mortality can be reduced by screening, and medical organizations recommend regular screening among persons of average risk aged 50 years or older. We sought to determine whether appropriate screening has become more widespread now that consensus over its value has been achieved. METHODS: We analyzed data from the 1992 and 1998 National Health Interview Survey, an in-person survey of a nationally representative sample of the U.S. population. Persons aged > or =50 years (4428 in 1992, 12,629 in 1998) were questioned about their use of colorectal cancer screening. RESULTS: Self-reported use of fecal occult blood testing and proctoscopy increased slightly from 1992 to 1998. In 1998, however, only an estimated 22.9% of Americans aged > or =50 years had been screened with either the home-administered fecal occult blood testing in the past year or proctoscopy within 5 years. Nearly half of fecal occult blood testings were performed with a sample taken during an in-office physical examination rather than with the recommended home kit. CONCLUSION: Most eligible persons are still not meeting the screening recommendations for colorectal cancer. Education is needed for both the public and health care providers to increase their compliance with current guidelines.     

Colorectal cancer-screening tests and associated health behaviors.

BACKGROUND: Studies have shown that screening reduces colorectal cancer mortality. We analyzed national survey data to determine rates of use of fecal occult blood testing (FOBT) and sigmoidoscopy, and to determine if these rates differ by demographic factors and other health behaviors. METHODS: A total of 52,754 respondents aged >or=50 years were questioned in the 1997 Behavioral Risk Factor Surveillance System (BRFSS) survey (a random-digit-dialing telephone survey of the non-institutionalized U.S. population) about their use of FOBT and sigmoidoscopy. RESULTS: The age-adjusted proportion of respondents who reported having had a colorectal cancer screening test during the recommended time interval (past year for FOBT and past 5 years for sigmoidoscopy) was 19.8% for FOBT, 30.5% for sigmoidoscopy, and 41.1% for either FOBT or sigmoidoscopy. Rates of use of colorectal cancer screening tests were higher for those who had other screening tests (mammography, Papanicolaou smear, and cholesterol check). There were also differences in rates of use of colorectal cancer screening tests according to other health behaviors (smoking, seat belt use, fruit and vegetable intake, and physical activity) and several demographic factors. However, none of the subgroups that we examined reported a rate of FOBT use above 29% within the past year or a rate of sigmoidoscopy use above 41% within the past 5 years. CONCLUSIONS: While rates of use of FOBT and sigmoidoscopy were higher among people who practiced other healthy behaviors, rates of use were still quite low in all subgroups. There is a need for increased awareness of the importance of colorectal cancer screening.     

Colorectal cancer screening among a sample of community health center attendees

To determine the rate of colorectal cancer screening in patients attending a sample of community health centers, medical records of 1,176 patients from eight community health centers were abstracted. Among the patients studied, 43.8% of patients had undergone at least one of the three colorectal screening tests (fecal occult blood test, colonoscopy, or flexible sigmoidoscopy) in the recommended interval. Colorectal screening in this community health center population was predicted by male gender, being African American, older age, having a greater number of chronic illnesses, a family history of colorectal cancer, and by having engaged in other preventive cancer screenings in the previous year. Although screening rates certainly were not optimal, they compare favorably to rates reported in national surveys for the general population. Our results add to a growing body of evidence that community health centers, despite serving disadvantaged populations, are able to deliver preventive care at rates comparable to health facilities used by the general population.     

Colorectal cancer screening knowledge and uptake in lebanon: a national survey

ObjectiveThe main aim of this national survey was to identify the levels of colorectal cancer screening knowledge and uptake in Lebanon.MethodsA total of 1200 participants were enrolled in this cross-sectional household survey targeting the Lebanese population aged 50 years and above. The sample was recruited using a two-stage stratified cluster sampling approach.ResultsOf the total sample, 38.3% knew about any screening test for colorectal cancer but only 7.5% had ever used any. Thirty-nine percent of the participants rated their risk of getting colorectal cancer as very low or low, and only 53.5% were confident in their ability to undertake a screening test. Almost all participants agreed that medical advice and test reimbursement would encourage them to do a screening test. At the multivariate analysis level, hearing of an awareness campaign in the last two years showed the strongest association with the knowledge of a colorectal cancer screening test with an estimated OR_adj = 5.12 (95%CI: 3.67 – 7.15). Other factors that were significantly associated with this knowledge variable included: a family history of colorectal cancer, a personal history of colorectal illness, having a health coverage, and knowledge of colorectal cancer signs and symptoms.DiscussionThis national study highlights an alarming lack of uptake and low levels of knowledge of colorectal cancer screening tests even though it is among the most prevalent cancers in Lebanon and its prevalence has been continuously increasing in the past years. The evidence suggests that people who had an experience with colorectal cancer diagnostic tests, either personally or through a family member, and those who have heard of an awareness campaign about colorectal cancer in the last two years are more likely to know its screening tests.ConclusionColorectal cancer screening knowledge and uptake in Lebanon are limited and justify the need for public health interventions. This study gives evidence that awareness campaigns, coupled with the involvement of medical providers and the reimbursement of screening test fees, would alleviate the burden of colorectal cancer in Lebanon.     

Factors Influencing Colorectal Cancer Screening in Low-Income African Americans in Tennessee

This study examined demographic and lifestyle factors that influenced decisions and obstacles to being screened for colorectal cancer in low-income African Americans in three urban Tennessee cities. As part of the Meharry Community Networks Program (CNP) needs assessment, a 123-item community survey was administered to assess demographic characteristics, health care access and utilization, and screening practices for various cancers in low-income African Americans. For this study, only African Americans 50 years and older (n = 460) were selected from the Meharry CNP community survey database. There were several predictors of colorectal cancer screening such as being married and having health insurance (P < .05). Additionally, there were associations between obstacles to screening and geographic region such as transportation and health insurance (P < .05). Educational interventions aimed at improving colorectal cancer knowledge and screening rates should incorporate information about obstacles and predictors to screening.     

Preference-based electronic decision aid to promote colorectal cancer screening: results of a randomized controlled trial

OBJECTIVE: Despite the burden of colorectal cancer and improved health care outcomes with early detection and treatment, screening rates among eligible adults are low. We previously developed through a series of studies an interactive electronic tool, Colorectal Web, to promote colorectal cancer screening. METHOD: From May 2002 to December 2003, we conducted a randomized controlled trial of Colorectal Web compared to a standard Web site on colorectal cancer screening in urban, suburban, and rural communities in Michigan with high colorectal cancer burden. Study participants were age 50 years and older, with no previous colorectal cancer screening. Major outcome was screened for colorectal cancer by 24 weeks post-intervention. RESULTS: 174 eligible adults were randomized and participated. Immediately post-intervention, Colorectal Web participants were significantly more likely to have a preferred colorectal cancer screening method, but this difference did not persist at subsequent follow-up. Eighty-nine participants had been screened for colorectal cancer by 24 weeks post-intervention. The probability of being screened for the Colorectal Web intervention study arm compared to the control is OR=3.23 (2.73-3.50 95% Confidence Interval). CONCLUSION: Colorectal Web is more effective than a standard colorectal cancer Web site at prompting previously unscreened individuals to choose a preferred colorectal cancer screening test and to be screened for colorectal cancer.     

Build it, and will they come? Unexpected findings from a study on a Web-based intervention to improve colorectal cancer screening

Given the extensive use of the Internet for health information, Web-based health promotion interventions are widely perceived as an effective communication channel. The authors conducted this study to determine use of a Web-based intervention intended to improve colorectal cancer screening in a population of women who are at average risk and noncompliant to current screening recommendations. The study was a randomized controlled trial designed to compare the effectiveness of colorectal cancer screening educational materials delivered using the Internet versus a printed format. In 3 years, 391 women seen for routine obstetrics/gynecology follow-up at 2 academic centers provided relevant survey information. Of these, 130 were randomized to the Web intervention. Participants received voluntary access to a password-protected, study-specific Web site that provided information about colorectal cancer and colorectal cancer screening options. The main outcome measures were self-reported and actual Web site use. Only 24.6% of women logged onto the Web site. Age was the only variable that differentiated users from nonusers (p = .03). In contrast, 16% of participants self-reported Web use. There was significant discordance between the veracity of actual and self-reported use (p = .004). Among true users, most (81%) logged on once only. These findings raise questions about how to increase use of important health communication interventions.     

Factors Influencing Choices for Colorectal Cancer Screening Among Previously Unscreened African and Caucasian Americans: Findings from a Triangulation Mixed Methods Investigation

We investigated factors that influence choice of colorectal cancer (CRC) screening test and assessed the most- and least-preferred options among fecal occult blood testing (FOBT), flexible sigmoidoscopy, colonoscopy, and double contrast barium enema among adults with varied race, gender, and geographic region demographics. Mixed methods data collection consisted of 10 focus group interviews and a survey of the 93 focus group participants. Participants were ≥50 years of age and reported not having been screened for colorectal cancer in the last ten years. Analyses examined differences by race, gender, and geographic location. Participants had modest knowledge about CRC and there were fewer correct answers to knowledge questions by African Americans. Participants recognized value of early detection, and identified health symptoms and their doctor’s recommendation as influential for obtaining CRC screening. They chose colonoscopy and FOBT as the most preferred tests, while barium enema was least preferred. The analysis revealed intra-group variations in preference, though there were no significant differences by race, gender, or location. Openness of discussing this sensitive topic, lack of knowledge about colorectal cancer and screening costs, and diversity of preferences expressed within study groups suggest the importance of patient-physician dialogue about colorectal cancer screening options. New approaches to promoting colorectal cancer screening need to explore methods to facilitate patients establishing and expressing preferences among the screening options.     

Predictors of Colorectal Cancer Screening Prior to Implementation of a Large Pragmatic Trial in Federally Qualified Health Centers

Colorectal cancer screening can prevent cancer deaths. Federally qualified health centers serve a unique patient population that often is not screened. Knowing who in this environment is getting screened via fecal testing and via colonoscopy can assist in tailoring intervention to raise rates of colorectal cancer screening. We examined patient-level and neighborhood-level characteristics associated with being up to date with colorectal cancer screening guidelines. We also examined associations between these factors and being screened with a fecal test. We observed an increase in colorectal cancer screening rates from 2010 to 2015. Adjusted analyses revealed that the following factors were significantly associated with colorectal cancer screening: aged 65 or older, having any type of insurance, previous outpatient visits, and current or other preventive screenings. Among adults aged 50–75 who were up to date with colorectal cancer screening, factors associated with use of fecal testing, as opposed to colonoscopy, were: being younger, speaking a non-English language, being uninsured, having prior office visits, and having had a flu shot in past year. Our findings may inform clinic-based effort to raise rates of colorectal cancer screening, especially in the community clinic setting. Trial Registration: ClinicalTrials.gov, NCT01742065.     

Communication Competence,Social Support,and Depression Among College Students: A Model of Facebook and Face-to-Face Support Network Influence

Breast Cancer Screening in Rural Populations: A Pilot Study

This report describes the development and implementation of a pilot intervention project designed to determine the economic, logistic, behavioral, and attitudinal variables that influence rural women's participation in a community-based breast cancer screening program. This paper reports on survey responses of women who registered for this pilot breast cancer screening program. It includes information on all women who registered for the project--both those who received breast cancer screening and those who did not. The study is a pilot intervention project, the overall goal of which was to develop a network of community providers, organizations, and volunteers to facilitate breast cancer screening among rural women. Of the 159 women registered for this pilot program, 101 (63.5%) were screened (receiving both a clinical breast examination and mammogram). The attitudes of women surveyed through the project confirm the importance of a physician recommendation for breast cancer screening. More than 90 percent of both the screened and unscreened groups of women stated that a doctor's recommendation to have breast cancer screening is important. Further, nearly 42 percent of the unscreened group had never had a physician recommend breast cancer screening. Despite existing barriers to screening, this pilot study demonstrated that health care professionals and regional organizations that have not traditionally been associated with delivering health care in this particular community setting can successfully work together to implement breast cancer screening programs.     

Knowledge, Attitudes, Beliefs, and Personal Practices Regarding Colorectal Cancer Screening Among Health Care Professionals in Rural Colorado: A Pilot Survey

ABSTRACT:  Purpose: This study reports the baseline knowledge, attitudes, beliefs, and personal practices of health care professionals regarding colorectal cancer (CRC) screening in the High Plains Research Network (HPRN) of rural Colorado prior to a community-based educational intervention. It also examines the association between health care staff members' knowledge, attitudes, beliefs, and personal practices for CRC screening and patient screening levels by practice. Methods: Surveys were mailed to health care professionals in the HPRN. Participating clinics (n = 21) distributed patient surveys on CRC screening to persons aged ≥50 for a 2-week period in 2006. Results: The survey response rate was 81% for providers (n = 46) and 90% for nursing staff (n = 63). Only 54% of health care professionals knew CRC is a leading cause of cancer deaths. When surveyed on their attitudes toward colon cancer, 92%"strongly agreed" or "agreed" that colon cancer is preventable. About 99% (n = 107) of providers and nurses "strongly agreed" or "agreed" that testing could identify problems before colon cancer starts. Most health care professionals (61%) aged ≥50 years had previously been tested and were up-to-date (52%) with screening. Provider knowledge was significantly associated with higher patient screening (P = .02), but provider attitudes and beliefs were not. Moreover, personal screening practices of health care professionals did not correlate with more patients screened. Conclusion: Background knowledge of CRC among HPRN health care professionals could be improved. The results of this pilot study may help focus effective approaches such as increasing provider knowledge to enhance CRC screening in the relevant population.

Colorectal Cancer Screening Adherence in African–American Men and Women 50 Years of Age and Older Living in Maryland

African Americans experience disproportionate incidence and mortality rates from colorectal cancer (CRC). This health disparity is partially explained by low participation in screening. This study aimed to identify factors influencing adherence to colorectal cancer screening among African Americans. Telephone interviews were conducted with African Americans living in Maryland (57% response rate). A total of 504 respondents agreed to participate. The survey primarily assessed participation in CRC screening, health beliefs and attitudes about CRC screening, and demographics. Nearly 77% of respondents reported being adherent to CRC screening guidelines. Of those not adherent, nearly 50% reported not ever receiving a physician recommendation to be screened. Having health insurance was a strong correlate of adherence. Study participants with greater perceived CRC risk were more likely to be adherent. Further, those who reported that they were caregivers were less likely to be adherent to screening. Findings indicate that those who were the primary care takers of children or disabled persons were less likely to participate in CRC screening. Efforts are needed to ensure that caregivers do not neglect their own preventive health, including CRC screening. Further, access to care and health insurance coverage also appear to be an important factor for participation in CRC screening. Ensuring that those who do not have adequate healthcare coverage are not excluded from participation in CRC screening due to cost should be an important priority if reduction in CRC health disparity is to be achieved.     

Recollection of previous colon cancer screening in Minnesota adults

Regularly scheduled screening of patients has been shown to be effective for decreasing morbidity and mortality from colorectal cancer. We used a questionnaire to assess patients' ability to accurately recall the date and type of their most recent colorectal cancer screening. The study included 200 consecutive patients whose records indicated they had undergone previous colorectal cancer screening (8 patients were later excluded because they had been screened more than 5 years earlier). Overall, 32.3% of patients could not recall the date of their last colorectal cancer screening, 34.3% recalled the date inaccurately, and 33.3% recalled the date accurately within 1 month. The results suggest that recall alone is not sufficient to determine the date and type of previous colorectal cancer screening, especially if the screening was performed more than a year earlier.     

A general practice-based recruitment strategy for colorectal cancer screening

OBJECTIVE: To determine whether a screening recruitment strategy for first degree relatives of people with colorectal cancer is effective in enabling eligible relatives to request screening from their general practitioner (GP) and to assess acceptability to GPs and patients. METHODS: Thirty GPs, from 26 practices, and 303 of their patients aged over 50 who were first degree relatives of a person with colorectal cancer, participated in a randomised controlled trial of a GP-based recruitment strategy, in the Newcastle Area of New South Wales, Australia. RESULTS: The proportion of relatives requesting screening was statistically significantly higher in the intervention group than in the control group (18% compared to 4%, respectively; p = 0.01). CONCLUSIONS: Interest in the study by GPs was low, however for GPs who were involved, the recruitment strategy did prompt first degree relatives to discuss screening. The strategy may be even more effective when combined with other interventions such as a media campaign. The results may be generalizable to feasibility studies of general population screening for colorectal cancer in Australia. IMPLICATIONS: The results of this work are potentially informative to public health practice in Australia given the ensuing pilot programs of colorectal cancer screening.     

Colorectal cancer and its prevention: prevalence of beliefs,attitudes, intentions and behaviour

Abstract: There is so far only limited evidence from randomised controlled trials that screening for colorectal cancer using the faecal occult blood test produces significant mortality reductions in screened groups, but there is considerable activity and interest in the use of such screening in Australia. Beliefs, attitudes, intentions and behaviour in relation to colorectal cancer and screening were examined among participants 40 years and older (n = 1776) who took part in a representative population survey. While there were high levels of awareness of faecal occult blood test screening, most respondents had not had a test, nor did they intend to take a test in the future. Important determinants of participation in screening were a family history of colorectal cancer, a belief that bowel cancer can be cured if detected at an early stage, a perception of personal susceptibility to bowel cancer and an acceptance of the technique. Factors such as these are likely to influence the success of any future screening program in Australia.     

Factors associated with colorectal cancer screening among the US urban Japanese population

OBJECTIVES: The author examined the prevalence and predictors of colorectal cancer screening among the urban Japanese population of the United States. METHODS: A sample of Japanese residents of major US metropolitan areas completed a self-administered mailed survey. RESULTS: Physician recommendation, acculturation, and perceived psychological costs were consistent predictors of screening for colorectal cancer. Gender and marital status were related to screening via fecal occult blood testing; age, susceptibility, and health insurance were related to sigmoidoscopy/colonoscopy screening. CONCLUSIONS: Colorectal cancer screening among the urban Japanese population could be increased with interventions seeking to promote physician recommendations for screening, alleviate perceived psychological costs among patients, and improve physician-patient communication.     

Colorectal cancer screening, intentions, and predictors in Jewish and Arab Israelis: a population-based study.

Random samples of 358 Jews and 162 Arabs in Israel aged 50 to 75 were compared by telephone survey for colorectal cancer (CRC) screening performance and intentions. Participants completed questionnaires on CRC screening, health beliefs, health locus of control, and CRC worries; rate of CRC screening and intention to be screened proved lower among Arabs. They received fewer recommendations from physicians, perceived lower severity of CRC and lower benefits of early detection of CRC, and had lower cancer worries, lower internal health locus of control, and higher external health locus of control. Jewish/Arab ethnicity predicted ever undergoing screening and screening intention before cognitive perceptions and worries were entered. After that, perceiving higher susceptibility and more benefits to screening, and having lower external health locus of control predicted CRC screening and screening intention, which was associated with higher cancer worries. Programs should be tailored to address ethnic groups' different health beliefs.
