Abstract
Age related hearing loss is one of the most common chronic health conditions affecting the elderly people. With aging, risk of Presbycusis and hyperlipidemia increases. Although most studies do reach some sort of agreement, the evidence supporting a relationship between presbycusis and hyperlipidemia remains questionable. The objective of this study is to determine the association between age related hearing loss and hyperlipidemia and assess the severity of hearing loss in hyperlipidemic patients. This cross sectional analytic study was carried out at ENT Out Patient Clinic at Al Sader teaching Hospital from March 2019 to December 2019. A cross‑sectional study on 52 patients with Hyperlipidemia and 42 non Hyperlipidemic patients was carried out during March 2019 to December 2019. All patients were evaluated for hearing loss by subjecting to pure tone audiometry, blood investigations were done in form of lipid profile, blood sugars, thyroid function test, blood urea and serum creatinine levels. Group A consisted of 22 (42.3%) males and 30 (57.7%) female while group B consisted of 23 (54.8%) male and 19 (45.2%) female individuals. Audiological assessment by PTA was show that the prevalence of presbycusis among hyperlipidemic group more than non hyperlipidemic with significant statistical difference (P value <0.05). Prevalence was 76.9%. In conclusion; there is statistically significant association between presbycusis and hyperlipidemia especially those with hyercholestrolemia.
Highlights
Hearing is one of the most essential senses to human; it acts as a communication tool with the external environment and his or her family
The result of our study shows that the most prevalent type of hyperlipidemia was hypercholesterolemia and those patient have a two folds’ risk of presbycusis than those with other type of hyperlipidemia as seen in this agree with the studies of Yucel, Hilal et al [10] and Gopinath, Bamini et al [11] they found that high dietary intake of cholesterol was associated with an increased likelihood of sensorineural hearing loss
From the current study it can be concluded that there is a significant link between Presbycusis and hyperlipidaemia so it can be considered as risk factors for its occurrence
Summary
Hearing is one of the most essential senses to human; it acts as a communication tool with the external environment and his or her family. The thickening is more severe in the basal turn of the cochlea where the basilar membrane is narrow [4]. Intermediate Due to Possible changes in intracellular organelles involved in cell metabolism, decrease in synapse numbers and changes in endolymph composition [6]. Mixed A combination of the other five subtype [3]
