The effects of insurance coverage and ethnicity on mammography utilization in a postmenopausal population.
West J Med 1998;168(4):236-40.

“Despite the effectiveness of mammography as a method to detect breast cancer in women aged 50 years and older, many women do not obtain screening mammograms... Bivariate analysis indicated that the following factors were all strongly associated with having had a mammogram in the previous two years: having health insurance, a regular medical provider, an annual household income greater than $20,000, and a high-school diploma as well as being 65 years or older or white (P<0.001). After adjusting for all of these factors in multiple logistic regression analysis, it was found that ethnicity (White vs., Hispanic)was not significant. The results suggest that access to a regular provider could increase the use of screening mammography in underserved populations.”
