The article “The Adult Well Male Examination” (May 15, 2012, page 964) contained multiple errors. In the row on physical activity in Table 2 (page 966), the recommended minutes of moderate-intensity aerobic exercise should have been at least 150 minutes per week, rather than at least 250 minutes per week. This recommendation is from the U.S. Department of Health and Human Services. The statement should have read: “The U.S. Department of Health and Human Services recommends that men participate in at least 150 minutes of moderate-intensity aerobic exercise per week, as well as muscle strengthening at least twice per week.” The abstract (page 964), Table 4 (page 969), and the last sentence under the colorectal cancer section (page 969) contained incorrect statements regarding the recommended screening test interval for sigmoidoscopy combined with fecal occult blood testing. The recommended screening test interval should have been sigmoidoscopy every five years combined with fecal occult blood testing every three years. The online version of this article has been corrected.
