Insights
Neonatal hearing screening identified several risk factors for infant hearing loss, including family history, infections, and low birth weight. Early intervention is crucial for infants diagnosed with hearing impairment through newborn hearing programs.
Area of Science:
- Neonatal care
- Audiology
- Public health
Background:
- Neonatal Hearing Screening and Early Intervention (NHSEI) programs aim to identify infants with hearing impairment.
- Understanding associated risk factors is crucial for targeted interventions.
Purpose of the Study:
- To determine factors associated with hearing loss in infants within the NHSEI program.
Main Methods:
- An analytical cross-sectional study included 234 infants.
- Hearing was assessed using transiently evoked otoacoustic emissions (TEOE).
- Variables included infant age, sex, gestational age, and perinatal history; data analyzed via logistic regression.
Main Results:
- Risk factors significantly predicted hearing loss (Nagelkerke R square = 77%).
- Associated factors included inherited conditions, infections, craniofacial abnormalities, low birth weight, respiratory distress, and genetic syndromes (p < 0.05).
Conclusions:
- The incidence of hearing impairment (5/234) was higher than previously reported.
- Identifying these risk factors can improve early detection and intervention strategies.
Background:
Neonatal Hearing Screening and Early Intervention (NHSEI) is a screening program to evaluate all infants and identify those with hearing impairment. The objective of this work was to determine the factors associated with hearing loss in NHSEI program.
Methods:
Analytical cross-sectional study was performed. 234 infants were included in the NHSEI program, hearing was evaluated with transitory evoked otoacoustic emissions (TEOE) at frequencies of 1.5 to 4.5 kHz, and intensity of stimuli of 40-60 dB. The variables were: age from one to 28 days, sex, gestational age and perinatal history. Data was analyzed with descriptive statistics and binary logistic regression.
Results:
The presence of risk factors in newborns resulted in significant omnibus test (p < 0.05) predicted value by Nagelkerke R square model of 77%. The background inherited family acquired infection, craniofacial abnormalities, low birth weight, respiratory distress at birth and genetic syndromes were factors significantly associated (p < 0.05) to hearing loss in infants.
Conclusions:
The incidence of hearing impairment in infants diagnosed by newborn hearing program was higher (5/234 newborns) than the reported in the literature.
