Abstract

Context: Congenital cytomegalovirus (cCMV) infection is the most common infectious cause of birth defects and the leading non-genetic cause of sensorineural hearing loss in the United States. Prior national cCMV infection prevalence estimates were based on one multi-site screening study conducted between 2007 and 2012 and were not adjusted for sociodemographic characteristics, such as maternal race and ethnicity or age.

Objective: This study sought to estimate national and state-specific prevalence of cCMV infection in the United States, adjusted for maternal race and ethnicity and maternal age group, by pooling estimates from published studies.

Design: We searched PubMed for U.S. cCMV newborn screening studies conducted between 2003 and 2023. From included studies, we abstracted maternal race and ethnicity- and age group-stratified cCMV prevalence to estimate strata-specific pooled prevalence. We obtained strata-specific weights from live birth data.

Main outcome measure: Estimated adjusted national and state-specific prevalence estimates from 2018 to 2022.

Results: Four studies (conducted 2004-2005, 2008, 2007-2012, and 2016-2021) were included for data abstraction. Overall, infants born to non-Hispanic Black (9.3 [8.2-10.5] per 1000) or non-Hispanic American Indian and Alaska Native (8.5 [2.1-33.2] per 1000) mothers had the highest cCMV prevalence. The estimated race and ethnicity-adjusted prevalence was 4.6-4.7 per 1000 live births nationally and ranged from 3.9 to 6.5 per 1000 across states from 2018 to 2022. Southern states and Alaska consistently had the highest cCMV prevalence. The estimated maternal age group-adjusted prevalence was 4.3-4.4 per 1000 live births nationally and ranged from 3.8 to 5.1 per 1000 across states from 2018 to 2022.

Conclusions: States with larger proportions of racial and ethnic minorities had higher estimated prevalence of cCMV infection compared to states with larger proportions of White persons. These estimates may be useful for informing cCMV surveillance at the jurisdiction level and developing tailored, culturally relevant education and prevention strategies for persons at higher risk.
