["Cancer screening is a behavior that represents investment in future health. Such investment may depend on how much 'future' a person expects.", 'The purpose of this study was to investigate the prospective association between perceived personal life expectancy and participation in fecal occult blood test screening for colorectal cancer (CRC) in a national program.', "Data were from interviews with 3975 men and women in the English Longitudinal Study of Ageing (ELSA) within the eligible age range for the national screening program (60 to 74\xa0years). Perceived life expectancy was indexed as the individual's estimate of their chance of living another 10-15\xa0years (exact time varied by age), assessed in 2008/2009. Participation in CRC screening from 2010 to 2012/2013 was assessed in 2012/2013. Logistic regression was used to estimate the association between perceived life expectancy and screening participation, adjusted for numeracy and known mortality risk factors.", 'Overall, 71% of respondents (2817/3975) reported completing at least one fecal occult blood test (FOBt) during the follow-up. Screening uptake was 76% (1272/1683) among those who estimated their 10-15-year life expectancy as 75-100%, compared with 52% (126/243) among those who estimated theirs as 0-25% (adjusted OR 1.74, 95% CI 1.29-2.34).'] Does perceived Life Expectancy be Associated with Colorectal Cancer Screening in England?
