The rates of mild or greater hearing loss in the underweight, normal, overweight, obese, and severely obese groups were 24.9%, 20.4%, 21.8%, 21.2%, and 24.1%, respectively. Mild severity of hearing loss was the most common in all five groups, followed by moderate, moderately severe, and severe hearing loss, in that order. Multivariate analysis, showed that the odds ratios of hearing loss in the severely obese, and underweight groups, compared with the normal group, were 1.312 and 1.282, respectively.

“…It has been shown in previous studies that compared with hearing loss diagnosed by audiogram, self-reported hearing loss is a relatively reliable indicator of hearing loss (22)(23)(24)(25). In addition, significant associations between other factors and risk of self-reported hearing loss have been observed using this method of assessment in NHS I and NHS II (14,(26)(27)(28)(29).…”

Aspirin, nonsteroidal antiinflammatory drugs (NSAID), and acetaminophen are commonly used. Frequent use of analgesics has been associated with a higher risk of hearing loss. However, the association between duration of analgesic use and the risk of hearing loss is unclear. We investigated the relationship between duration of analgesic use and self-reported hearing loss among 55,850 women in the Nurses' Health Study. Cox proportional hazards regression was used to adjust for potential confounders. During 873,376 personyears of follow-up (1990-2012), longer durations of NSAID use (for >6 years of use compared with <1 year, multivariable-adjusted relative risk = 1.10, 95% confidence interval: 1.06, 1.15; P for trend < 0.001) and acetaminophen use (for >6 years of use compared with <1 year, multivariable-adjusted relative risk = 1.09, 95% confidence interval: 1.04, 1.14; P for trend < 0.001) were associated with higher risks of hearing loss. Duration of aspirin use was not associated with hearing loss (for >6 years of use compared with <1 year, multivariableadjusted relative risk = 1.01, 95% confidence interval: 0.97, 1.05; P for trend = 0.35). In this cohort of women, longer durations of NSAID and acetaminophen use were associated with slightly higher risks of hearing loss, but duration of aspirin use was not. Considering the high prevalence of analgesic use, this may be an important modifiable contributor to hearing loss. acetaminophen; aspirin; hearing loss; nonsteroidal antiinflammatory drug Abbreviations: CI, confidence interval; NHS, Nurses' Health Study; NSAID, nonsteroidal antiinflammatory drug; RR, relative risk.

“…3 Obesity related atherosclerosis may lead to stiffening and constriction of the internal auditory artery and reduction in cochlear blood flow. 8 Reduced blood supply to cochlea, whether due to micro-vascular or macrovascular compromise, can lead to capillary constriction within the stria vascularis, cell death, and poorer hearing sensitivity.…”

BACKGROUND:A Body mass index [BMI] of 25 or greater is a significant health problem associated with a variety of disorders and in adults it has been found to be a risk factor for hearing loss. Higher BMI is independently associated with increased hearing loss. We investigated the hypothesis that young adults with a BMI of 25 or more are at increased risk of mild sensorineural hearing loss. AIMS AND OBJECTIVES: To assess hearing acuity in individuals with high BMI (≥25) by audiometric assessment and compare it with the control group (BMI <25). SETTINGS AND DESIGN: A comparative and cross sectional study among volunteers residing in Bengaluru. METHODS AND MATERIAL: Data collected from 2 groups containing 30 participants each, test group contained individual with a BMI of 25 or more and the control group consisted individuals with BMI of <25, in the age group of 18-35 yrs. Pure tone audiometry was carried out across various frequencies (0.5, 1, 2, 4, 6, 8 kHz) in both groups. STATISTICAL ANALYSIS: Student t-test was used to compare hearing thresholds across various frequencies in both groups. RESULTS: Compared to control group, high BMI (≥25) was associated with increased pure tone hearing thresholds across lower frequencies (0.5, 1, 2 kHz). The degree of hearing loss is mild (26-40dB). CONCLUSIONS: This study demonstrates that young adults with a BMI of 25 or more are at increasing risk of mild sensorineural hearing loss. KEYWORDS: High BMI, hearing loss, low Frequency hearing loss. INTRODUCTION:In 2010, overweight and obesity were estimated to cause 3·4 million deaths, 3.9% of years of life lost, and 3.8% of disability-adjusted life-years (DALYs) worldwide. 1 Worldwide, the proportion of adults with a body-mass index (BMI) of 25 kg/m 2 or greater increased between 1980 and 2013 from 28.8% (95% UI 28.4-29.3) to 36.9% (36.3-37.4) in men, and from 29. 8% (29.3-30.2) to 38.0% (37.5-38.5) in women. 1 A BMI of 25 or greater is a significant health problem associated with a variety of disorders and in adults it has been found to be a risk factor for hearing loss. 2 Acquired hearing loss is a highly prevalent disabling chronic condition, which can impair communication, social interaction, and adversely affect psychosocial well-being and quality of life. 3 Therefore identification of potentially modifiable risk factors for hearing loss is a compelling public health goal.Higher BMI is independently associated with an increased hearing loss, 3 a modifiable risk factor, and any disease process associated with it is preventable. Higher BMI is associated with poorer hearing sensitivities in a multinational European study 4 and a health ABC study. 5 Such a study is not conducted in Indian population.In this study we investigated the hypothesis that young adults with a BMI of 25 or more are at increasing risk of mild sensorineural hearing loss.
