Associations in breast and colon cancer screening behavior in women1

Rationale and objectives

Gender-based psychosocial factors appear to influence colorectal cancer (CRC) screening adherence. Given its near-universal acceptance by the public, screening mammography represents a potential “teachable moment” for educating patients about the risk of CRC. Accordingly, to better understand screening behaviors among women, data from the Behavioral Risk Factors Surveillance Survey (BRFSS) were analyzed to identify potential relationships that would allow interventions to enhance CRC screening.

Materials and methods

Women 50 years and older who participated in the BRFSS 2001 survey were included in the analysis. Colorectal, breast, and cervical cancer screening adherence with American Cancer Society guidelines was determined. We identified the association between breast and cervical cancer screening adherence and general health and demographic characteristics with CRC screening adherence.

Results

After adjustment for sociodemographic factors in a multivariate analysis, women 60–69 years old (adjusted odds ratio [OR], 1.50; P < .01) and 70–79 years old (adjusted OR, 1.39; P < .01), having achieved at least some high school (adjusted OR, 1.62; P < .01) or college (adjusted OR, 2.11; P < .01) education, having health coverage (adjusted OR, 1.67; P < .01) or a personal physician (adjusted OR, 1.60; P < .01), and adherence to screening mammography (adjusted OR, 2.42; P < .01) and Pap smear (adjusted OR, 1.70; P < .01) were independently associated with an increased likelihood CRC screening adherence. Women in self-reported good general health were less likely to have adhered to CRC screening guidelines (adjusted OR, 0.79; P < .01). Current smokers were also less likely to have adhered to CRC screening guidelines than were women who never smoked or formerly smoked (adjusted OR, 0.76; P < .01). Participants who adhered to both mammography and Pap smear guidelines were significantly more likely to adhere to CRC screening (51.5% CRC screening adherence) compared with women who adhered to neither screening test (8.2% CRC screening adherence), with an adjusted OR of 5.67 (P < .001). Participants who adhered to both mammography and Pap smear guidelines were significantly more likely to adhere to CRC screening than were women who adhered to either screening test (38.0% CRC screening adherence) with an adjusted OR of 1.94 (P < .001).

Conclusion

Women with up-to-date mammography and cervical cancer screening were more likely to be up-to-date with CRC screening. Regardless of the increased association between non−CRC-related cancer screening and CRC screening, rates of CRC screening utilization remained low in these otherwise compliant populations.

Survey design and data collection

The BRFSS is an annual telephone survey of a nationally representative sample of noninstitutionalized adults designed to measure preventive health practices and risk behaviors in adults (15). The BRFSS contains a module on women’s health, including items on breast and cervical cancer health behaviors, and a module on colon cancer screening behavior. Although the survey does not capture the results of the screening tests, the women’s health component does record the self-reported reason for last

Respondents versus nonrespondents to colorectal cancer screening items

A total of 53,752 women aged 50 and older participated in the 2001 BRFSS; 52,478 (97.6%) responded to CRC screening items (Table 1). In the states in which the women’s health module was administered, 13,048 women (97.8%) responded to the mammography items and 12,987 women (97.3%) responded to the cervical cancer screening items. The respondents, whose average age was 65 years, were predominantly white or Hispanic with a median annual income of $25,000–$49,999. Almost all participants attended

Discussion

The ACS predicted that CRC would be the cause of an approximate 56,000 deaths in the year 2005 (1). Despite ample evidence demonstrating the effectiveness of screening in reducing colon cancer mortality, several population-based studies illustrate the suboptimal rate of CRC screening adherence (20, 21, 22, 23). According to the National Center for Health Statistics, 34% of eligible women had completed an FOBT within the preceding 2 years compared with 36% of men. Similarly, 33% of women had

      Among women randomized to receive HPV self-sampling kits, preventive services uptake was higher in women who completed cervical cancer screening than in women who remained underscreened. Similar to previous studies, (Wirth et al., 2014; González and Borrayo, 2011; Kang et al., 2018; Bertaut et al., 2018; Carlos et al., 2005; Carlos et al., 2004) we observed positive associations between cervical cancer screening attendance and both mammography and CRC screening. We also observed a positive association between cervical cancer screening and influenza vaccination, in contrast to a previous study that found no association using self-reported data from the population-based 2016 Behavioral Risk Factor Surveillance System survey.(

      Consistent with our prediction, non-Hispanic whites exhibited the highest rate of adoption of the MT-sDNA screening test than did other racial and ethnic groups. We hypothesized greater use of MT-sDNA screening in individuals who have routinely engaged in other CRC screening and found that rates of MT-sDNA screening use were higher in those who had prior CRC screening, which is consistent with previous research.27-29 The rates of CRC screening in Olmsted County are relatively high, with 81% of the population reporting a prior colonoscopy or sigmoidoscopy.35

      Prior investigators have shown that women underuse colonoscopy compared with men. Reasons for this may include lower referral rates, potential for embarrassment, and preference (but unavailability) for female endoscopists.20-23 Our findings that women receive at least as much sedation as men (and in the case of benzodiazepines, more sedation than men) argue against sedation practices as a significant cause for colonoscopy underuse by women.

      The development cost increased by 14% or $54,956 when the overhead is 0.4 and productivity rate is 75%, whereas the development cost decreased by 4.7% or $18,205 when productivity rate is 95% (Table 4). The program was developed with a theoretical approach which combined CRC and BC screening with three arguments: First, similar constructs predict adherence to both screening behaviors, thus allowing developers to combine messaging (Carlos, Fendrick, Patterson, & Bernstein, 2005; Hall & Rossi, 2008). Secondly, combining screening interventions will provide a more efficient and cost effective method of increasing cancer screening in non-adherent women.
