A Media and Clinic Intervention to Increase Colorectal Cancer Screening in Ohio Appalachia

الملخص EN

Objective.

To test the effectiveness of a colorectal cancer (CRC) screening intervention among adults living in Ohio Appalachia.

Methods.

We conducted a group-randomized trial of a county-level intervention among adults living in 12 Ohio Appalachian counties who received a media campaign and clinic intervention focused on either CRC screening or fruits and vegetables.

Participants’ percentage within CRC screening guidelines was assessed with cross-sectional surveys conducted annually for four years, and validated with medical record review of screening.

Results.

On average, screening data were obtained on 564 intervention and 559 comparison participants per year.

There was no difference in the Wave 4 CRC screening rates of intervention and comparison counties (35.2% versus 31.4%).

Multivariate analyses found that high perceived risk of CRC, willingness to have a CRC test if recommended by a doctor, doctor recommendation of a CRC screening test, and patient-physician communication about changes in bowel habits, family history of CRC, and eating fruits and vegetables were significant ( p < 0.05 ) predictors of being within CRC screening guidelines.

Conclusions.

The intervention was not effective in increasing CRC rates among Ohio Appalachian adults.

Future research should determine how media and clinic-based interventions can be modified to improve CRC screening rates among this underserved population.
