Exploring health disparities in congenital CMV (cCMV): a study in a Somali-American community to assess awareness of cCMV and facilitate understanding of universal cCMV screening

Background: Congenital cytomegalovirus (cCMV) disproportionately impacts black and multiracial infants. While there have been strides made to address this health disparity, strategies to increase awareness and knowledge of cCMV have not been investigated in a Somali community. Methods: Two survey study strategies (in-person and online), consisting of a pre-survey test, educational intervention, and a post-survey, were designed to gauge knowledge and perceptions about cCMV among Somali women aged 18 to 40 years old. Results: 96 respondents partook in the online module, and 15 in the in-person event. On recruitment, < 45% of women were aware of cCMV. Following the pre-intervention survey, educational modules were conducted, and the survey repeated. For statistical comparisons, a point was assigned for each correct survey query, and the mean of correct responses tabulated for pre- and post-surveys. In the online intervention, mean scores changed from 55 to 87% (paired t-test, p = 0.001), whereas in the in-person intervention, mean scores changed from 65 to 87% (paired t-test, p = 0.007), demonstrating enhanced cCMV awareness upon completion of both interventions. Using multiple linear regression, the expected post-test score was 2% (95% CI [− 8%, 12%]) higher for the online module compared to the in-person module, adjusting for pre-test score. Conclusion: Both interventions were successful in enhancing knowledge about cCMV in this population, although there was no evidence either intervention was substantially better than the other. Educational efforts will be critical in enhancing the trust required to facilitate diagnostic evaluation and treatment of newborns identified with cCMV in this high-risk population.
