Increasing Use of Mammography Among Older, Rural African American Women: Results From a Community Trial

Objectives. A community trial was undertaken to evaluate the effectiveness of the North Carolina Breast Cancer Screening Program, a lay health advisor network intervention intended to increase screening among rural African American women 50 years and older.\r\nMethods. A stratified random sample of 801 African American women completed baseline (1993–1994) and follow-up (1996–1997) surveys. The primary outcome was self-reported mammography use in the\r\nprevious 2 years. Results. The intervention was associated with an overall 6 percentage point increase (95% confidence interval [CI] =-1, 14) in communitywide mammography use. Low-income women in intervention counties showed an 11 percentage point increase (95% CI = 2, 21) in use above that exhibited by lowincome women in comparison counties. Adjustment for potentially confounding characteristics did not change the results. Conclusions. A lay health advisor intervention appears to be an effective public health approach to increasing use of screening mammography among low-income, rural populations.
