Although prior studies have shown that African American smokers are likely to carry some of the genetic variants associated with smoking risk, additional research with African American smokers is needed to replicate these findings. Limited information is available on interest in participating in research to identify genetic risk factors for smoking among African American smokers; therefore, the goals of the present study were to describe intentions to participate in smoking and genetics research, and to determine factors that are associated with participation intentions. Subjects were 128 African American male and female adult smokers. Sociodemographic characteristics, clinical factors, attitudes about genetic testing, and intentions to participate in genetics research were evaluated during a structured telephone interview. Overall, 58% of respondents reported that they would be very likely to participate in research to identify genetic risk factors for smoking. Greater beliefs about the benefits of participating in medical research (odds ratio, 3.17; 95% confidence interval, 1.45-6.94; P = 0.004) and fewer perceptions of the limitations and risks of genetic testing (odds ratio, 0.90; 95% confidence interval, 0.82-0.98; P = 0.01) had significant independent associations with reporting a high likelihood of participating in this type of research. Recruitment messages and protocols that address the benefits of research participation, as well as concerns about the limitations and risks of genetic testing, may enhance African American participation in research on genetics and smoking.
