Healthy People 2010 Goal Used in Modeling

3-12b. Increase the proportion of adults who have received a sigmoidoscopy at some point in their lives.

We expanded this objective to include adults who have received either a sigmoidoscopy or colonoscopy. At the time this target was originally set, sigmoidoscopy was the preferred test method. Since then, studies have shown additional benefit from colonoscopy, and it has become more widely used. It is, however, a more costly and invasive procedure and carries a slightly increased risk, so current recommendations are for having either of the tests.
