Black women may not be getting mammograms as often as white women, despite a widespread belief that this particular racial disparity has been overcome, a University of Rochester Medical Center study shows.
Study author Kevin Fiscella, M.D., M.P.H., is concerned that some doctors might be relying on a cursory view of national data that suggests the racial gap is closed. His analysis raises questions about the accuracy of mammography rates, which are important as medical authorities try to determine why the incidence of breast cancer is lower in black women than in white women, yet the death rate is higher among blacks.
Fiscella examined the methodology used by a large national survey of yearly mammography rates among 3,090 women ages 40 and older. He found that depending upon the way a survey question is phrased, the responses among black and white women can vary as much as 13 percent.
“How you ask a question clearly matters,” said Fiscella, an associate professor in the UR Departments of Family Medicine and Community and Preventive Medicine. The study is published in this month’s Preventive Medicine journal.
Using the 1996 Medical Expenditure Panel Survey, which is designed to assess national patterns of health care use and costs, Fiscella focused on two key questions.
The first question was, “How long has it been since you’ve had a mammogram?” Most women of all races and ethnicities tend to underestimate how long it’s been: They’ll circle 1 year, for example, when in fact it’s been 18 months or 2 years since their last mammogram. Indeed, the responses showed no significant differences in mammogram rates among black, white and Hispanic women.
