Abstract

Aim: Anaemia is a prevalent medical condition that impacts a significant proportion of the worldwide populace. While the cardiovascular and respiratory systems' influence on anaemia has been extensively researched, its effect on the auditory system remains unclear. The objective of this investigation was to assess the pure tone audiometry of individuals with anaemia and establish a connection between the type of hearing impairment and the level of anaemia, if any.

Materials and methods: This cross-sectional study comprised 100 patients who were diagnosed with anaemia. All study participants underwent a thorough general examination and hearing assessment, which encompassed tuning fork tests, and pure-tone audiometry. Statistical analysis was utilized to determine the type and severity of hearing loss and its correlation with the degree of anaemia.

Results: Our research findings indicate that 46.8% of moderately anaemic patients and 62.9% of patients with severe anaemia exhibited sensorineural hearing loss. A significant correlation was observed between the degree of anaemia (p < 0.05) and hearing loss. Our research findings indicate that individuals with moderate and severe anaemia exhibit a notably greater incidence of hearing impairment in comparison to those with mild anaemia.

Conclusion: The research findings thus suggest a potential correlation between anaemia and auditory impairment. The timely identification and management of anaemia could potentially play a crucial role in preventing or reducing hearing impairment among individuals with anaemia. Additional research is required to clarify the mechanisms that underlie this association and to investigate possible interventions for mitigating the risk of hearing impairment in individuals with anaemia.

Keywords: Anaemia; Hearing Impairment; Hearing loss; Pure tone Audiometry; Tuning fork Tests.
