Introduction: These analyses were designed to elucidate U.S. physicians' perception of residential radon risk, as measured by the prevalence of residential radon testing using a representative sample of U.S. women physicians from the Women Physicians' Health Study database. In addition, characteristics of women physicians who were more likely to have conducted a residential radon test were identified.
Methods: A random sample (n = 4,501 respondents) of U.S. women physicians aged 30 to 70 was obtained in the Women Physicians' Health Study. Analyses were conducted using SUDAAN.
Results: The overall prevalence of residential radon testing among respondents was 18%, 2- to 6-fold higher than any estimate of residential radon testing in the general population. The strongest relationship with radon testing observed through logistic regression was with marital status; age, ethnicity, and region of residence were also related.
Conclusion: The study demonstrates that although U.S. women physicians are more likely to have conducted a personal residential radon test than the general population, 82% report not having done so. Increasing the awareness of physicians about the health risks associated with prolonged radon exposure will be essential if they are to play a role in addressing this important public health problem.
