RESUMEN
Congenital cytomegalovirus (CMV) is the leading cause of birth defects and developmental delays in the United States. However, only 13-22% of women in the United States have heard of CMV. This research assessed (1) the quantity and accuracy of CMV information included on pregnancy-related websites and reference books, and (2) whether CMV information was included less often than information about other birth defects or infections. A content analysis of 37 pregnancy reference books and seven websites was conducted. The data collection instrument represented categories describing CMV, transmission, and prevention. CMV subject matter experts at the Centers for Disease Control and Prevention reviewed the instrument. Each book and website was coded independently by two different coders. Twenty-one reference books and seven websites included CMV content. CMV was less likely to be included as a topic than other infections or birth defects. There were fewer sentences about CMV than toxoplasmosis, Down syndrome, or HIV. Book length was associated with increased likelihood of including CMV. How to prevent CMV transmission was discussed only half the time. Though limited, nearly all the CMV information was accurate. Pregnancy-related reference books and websites contain limited CMV information. Books are less likely to include CMV as compared to other infections and birth defects. Most of the CMV information is accurate. There is inadequate coverage given to prevention of CMV transmission, which may contribute to CMV remaining a continued leading cause of birth defects in the United States.
