Female employee participation in a worksite mammography screening program

We conducted a survey of 1,184 women 35 years of age or older who were employees of a company in Los Angeles County, California, to determine why some women participated in a worksite mammography screening program whereas others did not. Of the 111 who accepted a mammogram, 90 responded to the survey; of the 1,073 who declined mammography, 620 responded. The women were predominantly white, were well educated, and had health insurance. Of the 111 women who received mammograms, one was diagnosed with carcinoma. Seventy-three percent of the respondents to the survey 40 years of age or older who declined mammograms had already fulfilled American Cancer Society (ACS) guidelines for mammography screening at the time of the program. Women who accepted a mammogram were more likely to have had at least one previous mammogram than were women who had not met ACS guidelines yet who declined screening. We conclude that many female employees who are white, are well educated, and have health insurance may not participate in a worksite mammography screening program because they have been screened elsewhere. Companies providing worksite mammography screening should target education to women who have not met ACS guidelines, especially those who have never had a mammogram.
