Rates for TBSE increased with age and education level. Compared with those aged 18 to 29 years, the odds of those aged 30 to 39 years having had a TBSE in the past year were 30% greater. The odds of those in their 40s, 50s, 60s, and 70s having a recent TBSE were, respectively, 1.7, 2.5, 3.4, and 4.4 times greater than those aged 18 to 29 years. A similar dose-response relationship was observed with increasing education level. The odds of those with a high school diploma having had a TBSE within the past year were 60% greater than those with an eighth grade education or less. Those of individuals attending some college, 4 years of college, and 5 or more years of college were, respectively, 2.3, 2.9, and 3.2 times greater than the odds of having a TBSE among those with an eighth grade education or less.
