Prevalence and correlates of repeat mammography among women aged 55-79 in the Year 2000 National Health Interview Survey

Prev Med. 2004 Jul;39(1):1-10. doi: 10.1016/j.ypmed.2003.12.032.


Background: Utilization of mammography has increased steadily since the early 1990s. It is now important to expand the attention given to obtaining repeat examination. This study examines the prevalence and cross-sectional correlates of repeat mammography, among women aged 55-79, using a 12-month (N = 3,502) and a 24-month interval (N = 3,491).

Methods: Data were from the Year 2000 Cancer Control Module of the National Health Interview Survey (NHIS-CCM). The NHIS-CCM asked about the most recent mammogram and the total number of mammograms over the prior 6 years. An algorithm estimated repeat mammography for the two intervals.

Results: Prevalence estimates were 49% for the 12-month interval, and 64.1% for the 24-month interval. Correlates of lower likelihood of repeat mammography for both indicators were: no regular source of care, having public or no health insurance, less than a college education, household income less than $45K, not being married, current or never smoking, age 65-79, and lower absolute risk of breast cancer (Gail Model score).

Conclusions: A substantial percentage of women do not receive repeat mammography. The correlates of repeat mammography were similar to those often found for ever-had and recent mammography. There is probably some imprecision in the prevalence estimates due to the nature of NHIS-CCM questions. Issues pertinent to the definition of repeat examination are addressed.
