Prevalence of Congenital Hearing Loss in Neonates in Neonatal Intensive Care Units in Mexico
Main Article Content
Abstract
Objective of the manuscript:This study aims to assess the prevalence of congenital hearing loss among neonates admitted to the Neonatal Intensive Care Unit at the General Regional Hospital Ignacio Zaragoza, Mexico City, and to explore the clinical associations related to this condition.
Design, methodology, or approach:An observational, retrospective study was conducted by collecting data from medical records of neonates admitted to the Neonatal Intensive Care Unit and subjected to hearing screening between January 1, 2020, and December 31, 2021. Descriptive statistics were used to analyze the prevalence and associations of hearing loss, with Pearson's chi-squared and Mann-Whitney U tests for comparisons.
Most important results:Among 210 included neonates, the prevalence of congenital hearing loss was 1.43%. Significant associated factors were neonatal asphyxia (OR: 136, 95% CI: 9.5-1939) and low Apgar scores at 5 minutes (OR: 14.3, 95% CI: 1.2-176.8).
Limitations or implications of the study:The moderate sample size and the study's unicentric nature suggest the need for broader and multicentric future research to confirm these findings.
Originality or value of the research:This study contributes to the limited literature on the prevalence and associated factors of congenital hearing loss in Neonatal Intensive Care Unit neonates in Mexico, emphasizing the importance of early detection and proper management.
Findings or conclusions:The identified prevalence and associated risk factors highlight the need for meticulous auditory surveillance in high-risk neonates, particularly those with neonatal asphyxia and low Apgar scores, to facilitate early interventions that may improve outcomes.
Keywords:Congenital hearing loss; Neonates; Neonatal Intensive Care Unit; Prevalence; Risk factors.
