In 2010, an estimated 64.5% of respondents aged 50–75 years reported having had one of the following colorectal screening tests recommended by USPSTF: FOBT within 1 year, sigmoidoscopy within 5 years with FOBT within 3 years, or colonoscopy within 10 years preceding the survey (Table 1). The proportion of respondents who reported having had a colorectal cancer test within the recommended interval increased with age, increasing education level, and increasing annual household income. The proportion was also greater for those with health insurance than for those without, those with a regular care provider than those without, and slightly greater for women than for men. A slightly greater proportion of whites reported being up-to-date with colorectal cancer testing compared with all other racial/ethnic groups.
The proportion of respondents who had colonoscopy as their most recent test (60.3%) was much greater than the proportion that had FOBT (11.7%) or sigmoidoscopy in combination with FOBT (1.3%) as their most recent test. The proportion reporting use of any of the three test options increased with age and was greater among those with insurance and those with a regular care provider. Although a very small proportion of respondents reported having had a sigmoidoscopy within 5 years with FOBT within 3 years, a slightly greater proportion reported having had a sigmoidoscopy alone within 5 years (5.7% [95% confidence interval (CI) 5.4%–5.9%]; data not shown). A greater proportion of blacks reported receiving FOBT within 1 year compared with all other members of racial/ethnic groups; a greater proportion of whites reported colonoscopy within 10 years compared with all other racial/ethnic groups. Minimal variation was noted in reported FOBT use by education level and household income, whereas the proportion of respondents reporting colonoscopy within the past 10 years increased substantially with increasing education level and increasing annual household income.
The proportion of respondents who reported having received any colorectal cancer test within the recommended interval was highest in Massachusetts (75.2%) and in New Hampshire (75.1%) and lowest in Oklahoma (54.1%) (Table 2). Connecticut had the largest proportion of respondents who reported colonoscopy within 10 years (72.5%), and West Virginia had the smallest (49.7%). California had the largest proportion of respondents who reported FOBT within 1 year (19.4%), and Utah had the smallest (4.7%). All states had
