Risk Factors Associated With Hearing Impairment in Infants and Children: A Systematic Review

Abstract

The purpose of the present systematic review was to synthesize evidence on associated risk factors of hearing loss (HL) in children. Evidence-based research articles on HL published between January 2013 and December 2022 using PubMed, Cochrane, and Scopus databases were searched. The study included children between zero and three years of age who have permanent bilateral/unilateral HL (BHL/UHL) by employing case-control studies, randomized controlled trials, nonrandomized studies, prospective or retrospective cohort studies, and studies with or without comparison groups. The Newcastle-Ottawa Scale (NOS) and the Joanna Briggs Institute (JBI) critical appraisal checklist for longitudinal and cross-sectional studies were used to rate the quality of the chosen studies. The studies that would be considered were reviewed by two independent authors, and a third author was contacted if there was a dispute. A preliminary literature search uncovered 505 articles from the electronic search and 41 studies by hand searching. Duplicate records were eliminated, leaving 432 records. The abstract and title were read, and 340 studies were eliminated. There were 92 articles in total that qualified for full-text screening. Among these, 75 articles were disregarded since they lacked information or failed to assess the risk factors for HL. The qualitative synthesis, therefore, included 17 articles. Most often, cross-sectional study designs were used in the studies that were reviewed, which were then followed by longitudinal studies. Three of the studies that were reviewed used a prospective cohort design. The quality of all the included studies was rated to be good. The current review revealed that the primary statistically significant risk factors for HL included ventilator support; craniofacial anomalies; low birth weight (LBW); forceps delivery; loop diuretics; meningitis; asphyxia; intensive care; consanguinity; sepsis; Apgar scores between 0 and 4 at one minute; toxoplasmosis, other agents, rubella, cytomegalovirus, and herpes (TORCH) infections; and hyperbilirubinemia.

The value of synthetic MRI in detecting the brain changes and hearing impairment of children with sensorineural hearing loss

“…Some studies have shown that high risk factors that correlated with onset of SNHL, including preterm birth, low birth weight infants, hyperbilirubinemia, cytomegalovirus infection, inner ear abnormalities, etc. (Wroblewska-Seniuk et al, 2018 ; Alhazmi, 2023 ). Our research results indicated that NH and IEM are high-risk factors for SNHL, possibly due to our analysis being not performed in the general population but in one tertiary care hospital, where there is a big neurological intensive.…”
