This study identified key factors contributing to hearing loss in children, including genetic predispositions like consanguinity and family history. Early detection by parents within 3-6 months is crucial for intervention.

Area of Science:

  • Pediatrics
  • Genetics
  • Public Health

Background:

  • Hearing impairment presents a significant challenge in child development.
  • Understanding etiological factors is crucial for prevention and intervention strategies.

Purpose of the Study:

  • To investigate the etiological factors contributing to hearing loss in children at a school for the deaf.
  • To analyze the social outlook and demographic characteristics of parents with hearing-impaired children.

Main Methods:

  • A cross-sectional study was conducted at the Government Deaf and Dumb School, Thanjavur.
  • Data collected included family history, consanguinity, antenatal infections, birth complications, and ear-related issues.
  • Parental awareness regarding hearing disability detection age was assessed.

Main Results:

  • Boys constituted 60.2% of affected children.
  • High rates of consanguinity (65.4%), affected siblings (23.1%), and affected relatives (14.1%) were observed.
  • Antenatal infections (syphilis, chickenpox), certain medications (streptomycin, chloroquine), preterm birth, and birth asphyxia were noted contributing factors. Early detection occurred in 79% of cases between 3-6 months.

Conclusions:

  • Genetic factors (consanguinity, family history) and certain antenatal/perinatal complications are significant contributors to hearing loss.
  • Early parental detection of hearing disability is prevalent and essential.
  • Parental commitment plays a vital role in supporting children's self-dependency.
