Abstract/OtherAbstract:
The objective of this study was to determine the predictors of early-onset permanent hearing loss (EPHL) among undernourished infants in a low-income country where routine screening for developmental disabilities in early childhood is currently unattainable. All infants attending four community-based clinics for routine immunization who met the criteria for undernutrition by the Growth Standards of the World Health Organization (WHO) based on weight-for-age, weight-for-length and body-mass-index-for-age were enlisted. EPHL was determined after two-stage screening with transient-evoked otoacoustic emissions, automated auditory brainstem response and diagnostic evaluation. Factors predictive of EPHL were explored with multivariable logistic regression analysis. Some 39 (1.7%) infants from 2254 undernourished infants were confirmed with hearing loss (>30 dB HL). Bilateral EPHL was mild in 7 (17.9%) and moderate-to-profound in 26 (66.7%). EPHL was unilateral in 6 (15.4%). Multiparity, chronological age of more than 30 days, the absence of skilled attendant at birth and severe neonatal jaundice were associated with an increased risk of EPHL while having a Christian mother and exclusive breast feeding had protective effect against EPHL. EPHL is highly prevalent among undernourished infants and associated with modifiable risk factors that can be addressed at the community-level and used as a basis for targeted intervention in resource-poor countries.
