Abstract

Objective: To identify some risk factors for congenital hearing loss (CHL) of Vietnamese children. Study subjects and methods: A comparative cross sectional study between two group was conducted (on 300 CHL children at 7 Social Protection and Welfare Centers; Special Schools for Children with Disabilities across three regions of Vietnamvand 200 normal, healthy children without CHL at Dinh Ca Primary and Secondary School, Vo Nhai commune, Thai Nguyen province). Results: The risk factors for CHL include: children with a family history of hearing loss on the paternal side (POR=10.47; 95%CI: 1.46-456.69); children with mothers aged ≥35 years at birth (POR=3.45; 95%CI: 1.00-18.83); children whose mothers were infected with Rubella during pregnancy (POR=7.57; 95%CI: 1.08-327.58); premature infants (POR=2.37; 95%CI: 1.02-6.17); infants with congenital rubella infection (POR=4.85; 95%CI: 1.09-44.29); infants with congenital CMV infection (POR=6.86; 95%CI: 1.00-299.21). Conclusion: Family history, maternal age and maternal viral infection during pregnancy are risk factors for CHL.
