METHODS: A statewide, computer assisted random-digit dial telephone survey was conducted to gather information about OC prevention and early detection among Iowans age 18 and older. The survey contained 36 questions and lasted about ten minutes per respondent. Telephone numbers included landline and cell phone sampling lists provided by a private survey research firm. RESULTS: Of the 89 % of respondents that answered "yes" when asked if they had ever heard of OC, 54% had high OC risk factor knowledge; while of the eleven percent of those who said they had never heard of OC, 33% had high knowledge (p=0.003). Those that had an OC exam were more likely to have high OC risk factor knowledge (59%) compared with those that answered "no or don't know" to having had an OC exam (45%; p=0.002). Those that were "very or extremely" confident filling out medical forms were more likely to have high OC risk factor knowledge compared to respondents who were "not at all, slightly or moderately" confident filling out forms (54% vs. 45 %; p=0.097). CONCLUSIONS: The results suggest strongly that educational interventions are needed to increase knowledge of OC risk factors, early signs of OC, and the need to promote comprehensive OC examinations by healthcare providers.
