ABSTRACT
@#<p><strong>Objective:</strong> To determine the prevalence of hearing loss and otologic diseases among Filipinos living in the Southern Tagalog Region IV-A: CALABARZON (Cavite, Laguna, Batangas, Rizal and Quezon), Philippines.</p><p><strong>Methods:</strong></p><p><strong> Design:</strong> Retrospective Review of Community Survey Data</p><p><strong> Setting:</strong> Communities in Region IV-A provinces, Philippines</p><p><strong> Participants:</strong> 3267 residents of the five provinces aged 0 months and above</p><p> <strong>Results:</strong> About 71.29% and 74.60% had at least mild hearing loss, in right and left ears, respectively. For disabling hearing impairment, overall prevalence was 26.33%, distributed into 11.87% among 4 to 18-year-olds; 8.97% for 19 to 64-year-olds; and 3.17% for 65-year-olds and above. Absence of prevalent and hearing loss-associated diseases: serous otitis media [OR 0.362, 95% CI 0.167 to 0.782, p = .010], CSOM [OR 0.407, 95% CI 0.236 to 0.703, p = .001] COM [OR 0.229, 95% CI 0.106 to 0.494, p < .001] can decrease the risk for hearing loss development in the region. Prevention of noise-induced hearing loss or delay in the manifestation of presbycusis can reduce the risk of having hearing loss by as much as 75% [OR 0.253, 95% CI (0.180 to 0.355), p < .001]. All pure tone audiometry measurements were obtained with surrounding median ambient noise of 55dB (IQR 46 to 60dB).</p><p><strong>Conclusion:</strong> The prevalence of hearing loss among surveyed residents of the Southern Tagalog Region IV-A provinces was high compared to the previous nationwide study but low compared to other low- and middle-income countries. The top otologic conditions of this population (ear occlusion with ear wax, chronic suppurative otitis media, chronic otitis media, presbycusis, noise-induced hearing loss) were associated with hearing loss and their absence decreased the risks for hearing impairment.</p>
