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.
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.
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 ( < 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.
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.
贫血是一种普遍存在的医学状况，影响着全球很大一部分人口。虽然心血管和呼吸系统对贫血的影响已得到广泛研究，但其对听觉系统的影响仍不明确。本研究的目的是评估贫血患者的纯音听力测定结果，并确定听力障碍类型与贫血程度之间是否存在关联（若有）。
这项横断面研究包括100名被诊断为贫血的患者。所有研究参与者均接受了全面的体格检查和听力评估，包括音叉试验和纯音听力测定。采用统计分析来确定听力损失的类型和严重程度及其与贫血程度的相关性。
我们的研究结果表明，46.8%的中度贫血患者和62.9%的重度贫血患者表现出感音神经性听力损失。贫血程度（<0.05）与听力损失之间存在显著相关性。我们的研究结果表明，与轻度贫血患者相比，中度和重度贫血患者的听力障碍发生率明显更高。
研究结果因此表明贫血与听觉障碍之间可能存在关联。及时识别和管理贫血可能在预防或减少贫血患者的听力障碍方面发挥关键作用。需要进一步研究以阐明这种关联背后的机制，并研究可能的干预措施以降低贫血患者听力障碍的风险。
