Abstract

BACKGROUND:

In 2005, mammography rates in the United States dropped nationally for the first time among age-eligible women. An increased risk of breast cancer related to hormone therapy (HT) use reported in 2002 led to a dramatic drop in its use by 2005. Because current users of HT also tend to have higher mammography rates, the authors examined whether concurrent drops in HT and mammography use were associated.

METHODS:

Multivariate logistic regression was used to test for an interaction between HT use and survey year, controlling for a range of measurable factors in data from the 2000 and 2005 National Health Interview Surveys (NHIS).

RESULTS:

Women ages 50 to 64 years were more likely to report a recent mammogram if they also reported more education, a usual source of care, private health insurance, any race except non-Hispanic Asian, talking with an obstetrician/gynecologist or other physician in the past 12 months, or were currently taking HT. Women aged ≥65 years were more likely to report a recent mammogram if they also reported younger age (ages 65-74 years), more education, a usual source of care, having Medicare Part B or other supplemental Medicare insurance, excellent health, any race except non-Hispanic Asian, talking with an obstetrician/gynecologist or other physician in the past 12 months, or were currently taking HT.

CONCLUSIONS:

The change in HT use was associated with the drop in mammography use for women ages 50 to 64 years but not for women aged ≥65 years. NHIS data explained 70% to 80% of the change in mammography use. Cancer 2011;. © 2011 American Cancer Society.
