The Need

Despite their lower breast cancer incidence rates, older African American women have higher breast cancer mortality rates than White women. This can mostly be attributed to African American women's lower rates of mammography screening and a tendency for the cancer to be diagnosed at a later stage. Breast cancer screening rates are also lower in disadvantaged populations across all races, including women in rural areas, women of lower socioeconomic status, and women without insurance coverage. 

Lay health advisors have been proposed as an effective means of promoting breast cancer screening and other healthy behaviors.  Lay health advisors (e.g., peer volunteers, peer educators, lay community workers) are community members trained to act as links between the professional health care system and their own community. Studies conducted with disadvantaged populations have shown that lay health advisor interventions result in increased mammography screening among women recruited within their community.

The Program

The North Carolina Breast Cancer Screening Program (NC-BCSP) is a community-wide, lay health advisor intervention designed to increase mammography use among African American women living in rural communities. Lay health advisors are given instruction by community outreach specialists regarding breast cancer, breast cancer screening, and eligibility for screening payment programs.  Community outreach specialists (community leaders located in local health departments and federally funded rural health centers) are trained in public health principles, community outreach techniques, and program evaluation methods.  The community outreach specialists support lay health advisors through monthly meetings and assistance in organizing activities, including presentations to local community groups and at community events.

After training, the lay health advisors work to promote awareness and use of breast cancer screening among women in their communities. Lay health advisors also engage in one-on-one conversations with women they know in the community, using culturally sensitive materials to reinforce their promotion of breast cancer screening. Informational items (e.g., brochures, posters, mammography information) are also distributed throughout the community in settings such as churches and beauty parlors.  The lay health advisors facilitate access to services by accompanying women to clinics, providing transportation to mammography facilities, and disseminating information about screening services. 

With the assistance of community outreach specialists and lay health advisors, project staff members who have expertise in breast imaging meet with local radiology practices to ensure compliance with the Mammography Quality Standards Act and to raise awareness of African American women's barriers to mammography use. These teams also conduct brief training sessions with physician practices, community health centers, and health departments to promote breast cancer screening and mammography referrals among women who qualify for free breast cancer screening.

Implementation Guide

The Implementation Guide is a resource for implementing this program. It provides important information about the staffing and functions necessary for administering this program in the user's setting. Additionally, the steps needed to carry out the research-tested program, relevant program materials, and information for evaluating the program are included.

Community Preventive Services Task Force Finding
Guide to Community Preventive Services This program uses intervention approaches recommended by the Community Preventive Services Task Force: small media interventions (Breast Cancer Screening), one-on-one education interventions (Breast Cancer Screening), group education interventions (Breast Cancer Screening) and multicomponent interventions (Breast Cancer Screening).
Time Required

To administer NC-BCSP, time is required for:

- Community outreach specialists to be trained

- Community outreach specialists to train lay health advisors (three sessions of 3-4 hours each)

- Monthly meetings between the community outreach specialists and lay health advisors

- Lay health advisors to hold community activities twice per month

- Lay health advisors to hold one-on-one conversations with women in the community  (approximately two conversations per week per advisor)

- Community outreach specialists, lay health advisors, and project staff members to meet with local radiology practices

- Community outreach specialists, lay health advisors, and project staff members to conduct brief training sessions with physician practices, community health centers, and health departments

- Lay health advisors and community outreach specialists to work with providers and community organizations

Intended Audience
The primary audience for NC-BCSP is African American women 50 years and older, living in rural areas or small towns (i.e., populations below 5,000).
Suitable Settings
NC-BCSP is designed to be administered in rural and small-town community settings.
Required Resources

The NC-BCSP toolkit includes the following materials:

- Community Outreach Specialist and Lay Health Advisor Training Manual
- Training materials list
- Campaign materials list
- Newsletters
- Breaking the Silence video
- Beaded breast lump education necklace (optional)

About the Study

NC-BCSP was evaluated using a nonrandomized community trial that took place in eastern North Carolina in five intervention communities and five comparison communities, geographically separated by Pamlico Sound. The two sets of counties had similar demographic, geographic, and cultural characteristics, as well as similar access to health care and mammography services. Two-thirds of the counties' adult residents lived in rural areas or small towns with populations below 5,000. Thirty-seven percent of the community members were non-White, and 12% lived below the poverty line.

Two cohorts of African American women were chosen by using a systematic random sample to select census blocks from each county. Interviewers canvassed door-to-door in 520 selected blocks and approached 2,355 households. Of these, 2,120 households with at least 1 woman who was 50 years or older and did not have breast cancer agreed to participate. A random selection was then made from among these eligible households. A total of 494 women in the intervention group and 499 women in the comparison group were interviewed at baseline. Baseline data were collected in 1993-1994.

The intervention communities received NC-BCSP, while the comparison communities did not receive any intervention. However, the Centers for Disease Control and Prevention's Breast and Cervical Cancer Control Program, which funds mammograms for eligible low-income women, became available in all 10 counties 1 year after initiation of NC-BCSP. 

Follow-up data collection took place in 1996-1997 and included 390 intervention women and 411 comparison participants.  At both baseline and follow-up, trained female interviewers recruited from the community administered a 45-minute questionnaire in women's homes. In most cases, the 58 interviewers were matched in age and race to the women being interviewed. The baseline and initial follow-up interviews were conducted an average of 32 months apart for the intervention cohort (range 20-47 months) and 30 months apart for the comparison cohort (range 18-41 months).

Key Findings
  • Self-reported mammography use increased from 41% at baseline to 58% at follow-up for the intervention group, compared to an increase of 56% at baseline to 67% at follow-up for the comparison group (p<.05).

Additional Findings

  • At follow-up, self-reported advice received from a lay health advisor was 14% for the intervention group, compared to <1% for the comparison group (p<.01).
  • At follow-up, self-reported exposure to more than four intervention materials was 12% for the intervention group, compared to 2% for the comparison group (p<.01).
