Ear health and hearing in urban Aboriginal children.

Evaluate ear health and hearing among urban Aboriginal children and quantify relationships with child, family and social factors. Baseline questionnaire and ear health examinations from 1430 children with diagnoses (0.5-18 years) attending Aboriginal Health Services enrolled in SEARCH. Ear health outcomes were Otitis Media (OM), and hearing loss (three-frequency average hearing loss >20dB) diagnosed using pneumatic otoscopy, tympanometry, and audiometry. Half the children 0.5-3 years had OM (51.5%, 136/264). One third 0.5-18 years (30.4%; 435/1430) had OM, including 1.8% (26/1430) with perforation (0.8% chronic suppurative OM, 0.6% dry perforation and 0.4% acute OM with perforation). One quarter 0.5-18 years (25.7%; 279/1087) had hearing loss; 12.4% unilateral, 13.2% bilateral (70.6% with bilateral loss had concurrent OM). OM was associated with: younger age (0.5-<3 years versus 6-18 years) age-sex-site; adjusted prevalence ratio (aPR)=2.64, 95%, 2.18-3.19); attending childcare/preschool (aPR=1.24, 95%CI, 1.04-1.49); foster care (aPR=1.40, 95%CI, 1.10-1.79); previous ear infection/s (aPR=1.68, 95%CI, 1.42-1.98); and ≥2 people/bedroom (aPR=1.66, 95%CI, 1.24-2.21). Hearing impairment was associated with younger age (0.5-<6 years vs. ≥6 years aPR=1.89, 95%CI, 1.40-2.55) and previous ear infection (aPR=1.87, 95%CI, 1.31-2.68). Half the urban Aboriginal children in this cohort had OM and two-thirds with hearing impairment had OM. Findings highlight importance of early detection and support for ear health, particularly in pre-school-aged children with risk factors.
