The aim of this study was to assess the prevalence of selected cancer risk factor data from hospital outpatients and the proportion of 'at risk' patients who would like help from hospital staff to reduce risk factors. A touch-screen computer collected data from outpatients in Newcastle, NSW, Australia. Eight hundred and nineteen outpatients completed the computerized interview. Of these, 35% were smokers, of whom 25% said that they would like help to stop smoking; 47% were overweight, with 48% indicating that they wanted assistance; 17% consumed harmful levels of alcohol, with 2% wanting help; 30% of eligible women were overdue for a Pap test, of whom 75% said that they wanted a referral to be screened, and 25% were overdue for a mammogram, of whom 83% said that they would like a referral for an examination. Touch-screen computerized health risk assessments are practical for collecting and monitoring valid cancer risk factor data for hospital outpatients
