Colorectal cancer screening disparities related to obesity and genderBACKGROUND: Obesity is associated with a higher incidence of colorectal cancer and increased colorectal cancer mortality. Obese women are less likely to undergo breast and cervical cancer screening than nonobese women. It is not known whether obesity is associated with a lower likelihood of colorectal cancer screening. OBJECTIVE: To evaluate whether there is an association between body mass index (BMI) and rates of colorectal cancer screening. To examine whether BMI-related disparities in colorectal cancer screening differ between men and women. DESIGN AND SETTING: The Behavioral Risk Factor Surveillance System, a cross-sectional random-digit telephone survey of noninstitutionalized adults conducted by the Centers for Disease Control and Prevention and state health departments in the 50 states and Washington, DC in 1999. PATIENTS: Survey respondents (N= 52886) between 51 and 80 years of age representing 64563332 U.S. adults eligible for colorectal cancer screening. INTERVENTIONS AND MEASUREMENTS: Adjusted rates of self-reported colorectal cancer screening with fecal occult blood testing within the past year or endoscopic screening (sigmoidoscopy or colonoscopy) within the past 5 years. RESULTS: The colorectal cancer screening rate was 43.8% overall. The rate of screening by FOBT within the last year or endoscopic screening within the past 5 years was 39.5% for the morbidly obese group, 45.0% for the obese group, 44.3% for the overweight group, and 43.5% for the normal weight group. The difference in screening rates was entirely attributable to differences in BMI among women. After statistical adjustment for potential confounders, morbidly obese women were less likely than normal weight women to be screened (adjusted rate difference, -5.6%; 95% confidence interval, -8.5 to -2.6). Screening rates among normal weight, overweight, and obese women, and among men in different weight groups did not differ significantly. CONCLUSIONS: Colorectal cancer screening rates among age-eligible persons in the U.S. are disturbingly low. Morbidly obese women, who are at higher risk than others to develop and to die from colorectal cancer, are less likely to be screened. Efforts to increase colorectal cancer screening are needed for all age-eligible groups, but should also include targeted screening of morbidly obese women since they could reap substantial clinical benefits from screening.

Colorectal cancer screening in Massachusetts: measuring compliance with current guidelinesCONTEXT: Professional organizations have published guidelines for colorectal cancer screening. Defining which patients are currently, or should be, screened is an important clinical and public health issue. OBJECTIVE: To document the prevalence of colorectal cancer screening and profile the tests patients have had. DESIGN/POPULATION: A random-digit telephone survey of Massachusetts adults, 50 years of age and older. OUTCOME MEASURES: Percentage of persons ever and currently tested by fecal occult blood tests, flexible sigmoidoscopy, barium enema, colonoscopy, or some combination of these tests. RESULTS: Sixty-five percent of those contacted agreed to the telephone interview. Approximately 29% of the 1119 respondents had never had any currently accepted test, including 10% who reported having only a fecal occult blood test done in a provider's office and 19% who reported having no tests. At least 51% were currently tested by one or more tests for screening, diagnosis, or both. Another 10% were possibly current by colonoscopy or barium enema, both of which can be ordered for screening but are more commonly used to evaluate a problem, such as rectal bleeding, or for surveillance after identification of a polyp or other abnormality. An additional 11% had been tested at some point but were not current according to guidelines. CONCLUSIONS: Accurate assessment of rates of colorectal cancer screening is complex because of the multiple acceptable screening methods, the fact that patients may be tested for screening or diagnostic purposes, and the lack of adequate systems for tracking such testing. For accurate measurement, all methods must be assessed regardless of whether tests were ordered for screening, diagnosis, or surveillance.

Colorectal cancer screening participation: comparisons with mammography and prostate-specific antigen screeningOBJECTIVES: The relation of personal characteristics, health and lifestyle behaviors, and cancer screening practices to current colorectal cancer (CRC) screening was assessed and compared with those factors' relation to current mammography screening in women and prostate-specific antigen (PSA) screening in men. METHODS: A cross-sectional random-digit-dialed telephone survey of 954 Massachusetts residents aged 50 and older was conducted. RESULTS: The overall prevalence of current CRC screening was 55.3%. Logistic regression results indicated that family history of CRC (odds ratio [OR] = 1.98; 95% confidence interval [CI] = 1.02, 3.86), receiving a regular medical checkup (OR = 3.07; 95% CI = 2.00, 4.71), current screening by mammography in women and PSA in men (OR = 4.40; 95% CI = 2.94, 6.58), and vitamin supplement use (OR = 1.87; 95% CI = 1.27, 2.77) were significant predictors of CRC screening. CONCLUSIONS: Health and lifestyle behaviors were related to increased current CRC, mammography, and PSA screening. Personal factors independently related to CRC screening were not consistent with those related to mammography and PSA screening. This lack of consistency may reflect different stages of adoption of each type of screening by clinicians and the public.

Healthcare system factors and colorectal cancer screeningBACKGROUND: Developing effective programs to promote colorectal cancer (CRC) screening requires understanding of the effect of healthcare system factors on access to screening and adherence to guidelines. METHODS: This study assessed the role of insurance status, type of plan, the frequency of preventive health visits, and provider recommendation on utilization of CRC screening tests using a cross-sectional, random-digit-dial survey of 1002 Massachusetts residents aged > or =50. RESULTS: A broad definition of CRC screening status included colonoscopy or barium enema (screening or diagnostic) within 10 years, flexible sigmoidoscopy (FSIG) within 5 years, and fecal occult blood testing (FOBT) in the past year as options; 51.7% of subjects aged 50 to 64 and 61.5% of older subjects were current. The uninsured had the lowest current testing rate. Among insured participants, type of insurance had little impact on CRC testing; older subjects enrolled in HMOs had marginally higher rates, although not statistically significant. Increased frequency of preventive health visits and ever receiving a physician's recommendation for FSIG or ever receiving FOBT cards were associated with higher rates of CRC screening among both age groups. CONCLUSIONS: Even when broad criteria are used to define current CRC screening status, a substantial proportion of the age-eligible population remains underscreened. Obtaining regular preventive care and receiving a physician's recommendation for screening appear to be potent facilitators of screening that should be considered in designing promotional efforts.

Primary care, economic barriers to health care, and use of colorectal cancer screening tests among Medicare enrollees over timePURPOSE: Colorectal cancer (CRC) screening remains underutilized. The objective of this study was to examine the impact of primary care and economic barriers to health care on CRC testing relative to the 2001 Medicare expansion of screening coverage. METHODS: Medicare Current Beneficiary Survey data were use to study community-dwelling enrollees aged 65 to 80 years, free of renal disease and CRC, and who participated in the survey in 2000 (n = 8,330), 2003 (n = 7,889), or 2005 (n = 7,614). Three outcomes were examined: colonoscopy/sigmoidoscopy within 5 years (recent endoscopy), endoscopy more than 5 years previously, and fecal occult blood test (FOBT) within 2 years. RESULTS: Endoscopy use increased and FOBT use decreased during the 6-year period, with no significant independent differences between those receiving care from primary care physicians and those receiving care from other physicians. Beneficiaries without a usual place of health care were the least likely to undergo CRC testing, and that gap widened with time: adjusted odds ratio (AOR) = 0.27 (95% confidence interval [CI], 0.19-0.39) for FOBT, and AOR = 0.35 (95% CI, 0.27-0.46) for endoscopy in 2000 compared with AOR = 0.18 (95% CI, 0.11-0.30) for FOBT and AOR = 0.22 (95% CI, 0.17-0.30) for endoscopy in 2005. Disparities in use of recent endoscopy by type of health insurance coverage in both 2000 and 2005 were greater for enrollees with a high school education or higher than they were for less-educated enrollees. There were no statistically significant differences by delayed care due to cost after adjustment for health insurance. CONCLUSION: Despite expanding coverage for screening, complex CRC screening disparities persisted based on differences in the usual place and cost of health care, type of health insurance coverage, and level of education.
