Comparison of participants and nonparticipants in a work site cancer awareness and screening program

J Occup Med. 1989 Mar;31(3):221-32. doi: 10.1097/00043764-198903000-00007.


In 1985, Pennzoil Company offered a company-paid cancer awareness and screening program focusing on breast and colorectal cancers for its employees. Following a lecture/slide presentation, employees filled out a risk assessment questionnaire. Those at risk for breast and/or colorectal cancers were invited for consultation, mammography, and/or short colonoscopy. Overall completion rates were 49% for mammography, 20% for the fecal occult blood test, and 31% for short colon oscopy, but these rates varied by risk status. Moreover, the same demographic and risk factors were not consistently associated with completion of the same screening procedure across risk groups. Based on these findings, we suggest that different interventions may need to be developed depending on the risk characteristics of subgroups within the target population.
