Context Although some studies have shown that men are at greater age-specific risk for advanced colorectal neoplasia than women, the age for referring patients to screening colonoscopy is independent of sex and usually recommended to be 50 years.Objective To determine and compare the prevalence and number needed to screen (NNS) for adenomas, advanced adenomas (AAs), and colorectal carcinomas (CRCs) for different age groups in men and women.Design, Setting, and Patients Cohort study of 44 350 participants in a national screening colonoscopy program over a 4-year period (2007 to 2010) in Austria.Main Outcome Measures Prevalence and NNS of adenomas, AAs, and CRCs in different age groups for men and women.Results The median ages were 60.7 years (interquartile range [IQR], 54.5-67.5 years) for women and 60.6 years (IQR, 54.3-67.6 years) for men, and the sex ratio was nearly identical (51.0% [22 598] vs 49.0% [21 572]). Adenomas were found in 19.7% of individuals screened (95% CI, 19.3%-20.1%; n=8743), AAs in 6.3% (95% CI, 6.1%-6.5%; n=2781), and CRCs in 1.1% (95% CI, 1.0%-1.2%; n=491); NNS were 5.1 (95% CI, 5.0-5.2), 15.9 (95% CI, 15.4-16.5), and 90.9 (95% CI, 83.3-100.0), respectively. Male sex was significantly associated with a higher prevalence of adenomas (24.9% [95% CI, 24.3%-25.4%] vs 14.8% [95% CI, 14.3%-15.2%]; P
