Evaluation of Audiometric Test Results to Determine Hearing Impairment in Patients with Rheumatoid Arthritis: Analysis of Data from the Korean National Health and Nutrition Examination Survey.

ABSTRACT: This study aimed to evaluate the association between rheumatoid arthritis (RA) and hearing impairment in the Korean adult population. Audiometric and laboratory test data from the 2010-2012 Korean National Health and Nutrition Examination Survey (KNHANES) were used for analysis. The relationship between RA and hearing impairment was analyzed, adjusting for various known risk factors associated with hearing impairment. RA was defined in the questionnaire as "RA diagnosed by a physician (yes/no) through a standardized interview." We defined hearing impairment according to 2 categories of frequency (low/mid and high) as follows (average values in kHz): low/mid frequency, 0.5, 1.0, and 2.0, and high frequency, 3.0, 4.0, and 6.0. Of the subjects, 15,158 (weighted n = 32,035,996) completed the audiometric tests. The overall weighted prevalence of RA was 1.5%. The prevalence of hearing impairment was higher in the subjects with RA than in those without RA, in both, the low/mid- and high-frequency categories (21.1% vs 7.5%, p < 0.001 and 43.3% vs. 26.2%, p < 0.001, respectively). In the multivariable logistic analysis, RA (odds ratios [OR] 1.47, 95% confidence interval [CI] 1.05-2.06, p = 0.025) was an independent risk factor of low/mid-frequency hearing impairment along with age (OR 1.12, 95% CI 1.12-1.13, p < 0.001), current smoking (OR 1.27, 95% CI 1.03-1.56, p = 0.026), and college graduation (OR 0.53, 95% CI 0.39-0.72, p < 0.001). In the multivariable analysis of high-frequency hearing impairment, RA did not show any association with hearing impairment. This study suggests that RA is associated with low/mid-frequency hearing impairment after adjustment for various known risk factors. Further study is needed to verify the hearing impairment in RA.

Project description:ObjectivesHigh salt intake has a harmful effect on hypertension; however, the association between major adverse cardiovascular events (MACE) and salt intake is still controversial. Rheumatoid arthritis (RA) is also characterised by excess cardiovascular risk. However, few studies have investigated the combined role of salt intake and RA in MACE in the general Korean population. Here, we evaluated this relationship among the Korean adult population.DesignRetrospective, cross-sectional.SettingPopulation-based survey in Korea.MethodsThis study was based on the data of the seventh Korean National Health and Nutrition Examination Survey (2016-2018). The estimated 24-hour urinary sodium excretion (24HUNa), a surrogate marker for daily sodium intake, was calculated using the Tanaka equation and was stratified into five groups (<3, 3-3.999, 4-4.999, 5-5.999 and ≥6 g/day). Finally, data from 13 464 adult participants (weighted n=90 425 888) were analysed; all analyses considered a complex sampling design. Multivariable logistic regression for MACE as primary dependent variable was performed and adjusted for potential covariates.ResultsParticipants with MACE had higher 24HUNa levels and RA proportion than those without MACE (p<0.001). The association of MACE with 24HUNa was J-shaped with a gradual increase from about 3 g/day. The highest 24HUNa (≥6 g/day) group was significantly associated with increased prevalence of MACE compared with the reference group (3-3.999 g/day) after adjusting for all associated covariates (OR 6.75, 95% CI 1.421 to 32.039). In the multivariate logistic regression analysis, RA (OR 2.05, 95% CI 1.283 to 3.264) and the highest 24HUNa group (OR 6.35, 95% CI 1.337 to 30.147) were significantly associated with MACE even after adjusting for baseline covariates.ConclusionsThese nationally representative data suggest that RA and extremely high sodium intake are associated with MACE in the general adult Korean population. Avoiding extremely high salt intake and considering RA as an important risk factor for MACE might help promote public cardiovascular health.

Project description:BackgroundIn evaluating hearing disability in medicolegal work, the apportionment of age- and gender-related sensorineural hearing loss should be considered as a prior factor, especially for the elderly. However, in the literature written in the English language no studies have reported on the age- and gender-related mean hearing threshold for the South Korean population.ObjectiveThis study aimed to identify the mean hearing thresholds in the South Korean population to establish reference data and to identify the age- and gender-related characteristics.MethodsThis study is based on the Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012, which was conducted by the Korean government, the data of which was disclosed to the public. A total of 15,606 participants (unweighted) representing 33,011,778 Koreans (weighted) with normal tympanic membrane and no history of regular or occupational noise exposure were selected and analyzed in this study. The relationship between the hearing threshold level and frequency, age, and gender was investigated and analyzed in a highly-screened population by considering the sample weights of a complex survey design.ResultsA gender ratio difference was found between the unweighted and the weighted designs: male:female, 41.0%: 59.0% (unweighted, participants) vs. 47.2%:52.8% (weighted, representing population). As age increased, the hearing threshold increased for all frequencies. Hearing thresholds of 3 kHz, 4 kHz, and 6 kHz showed a statistical difference between both genders for people older than 30, with the 4 kHz frequency showing the largest difference. This paper presents details about the mean hearing threshold based on age and gender.ConclusionsThe data from KNHANES 2010-2012 showed gender differences at hearing thresholds of 3 kHz, 4 kHz, and 6 kHz in a highly-screened population. The most significant gender difference in relation to hearing threshold was observed at 4 kHz. The hearing thresholds at all of the tested frequencies worsened with increasing age. The mean hearing thresholds suggested in this study will be useful for the formulation of healthcare-related hearing policies and used as reference data for disability ratings for hearing loss due to various causes.

Project description:ObjectivesTinnitus and hearing loss commonly coexist, however, the temporal relation between tinnitus and hearing loss is complex and not fully understood. Our objective was to examine the longitudinal association between persistent tinnitus, bothersome tinnitus, and 3-year elevation of audiometric hearing thresholds.DesignWe conducted a longitudinal cohort study among 3106 women (mean age 59 years) who were participants in the Nurses' Health Study II (2012-2018). Information on tinnitus was obtained from biennial questionnaires. Longitudinal changes in air conduction thresholds (0.5 to 8 kHz) were assessed by pure-tone audiometry conducted by licensed audiologists at 19 audiology testing sites across the United States. Logistic regression was used to estimate multivariable-adjusted odds ratios (MVORs, 95% confidence interval [CI]) and evaluate the relations of persistent tinnitus (several days per week or more), bothersome tinnitus (interferes with work, sleep, or daily activities), and risk of 3-year elevation of hearing thresholds.ResultsPersistent tinnitus was associated with higher risk of 3-year elevation of hearing thresholds across a broad range of frequencies. Compared with women without tinnitus, the MVORs (95% CI) for ≥5-dB threshold elevation among women with persistent tinnitus were 1.01 (0.81, 1.25) at 0.5 kHz, 1.45 (1.17, 1.81) at 1 kHz, 1.25 (1.00, 1.56) at 2 kHz, 1.34 (1.07, 1.69) at 3 kHz, 1.34 (1.06, 1.70) at 4 kHz, 1.49 (1.16, 1.91) at 6 kHz, and 1.63 (1.25, 2.12) at 8 kHz. The magnitudes of the associations for ≥10-dB threshold elevation were similar. The magnitudes of the associations were substantially greater among women with bothersome tinnitus. For example, compared with women without tinnitus, the MVORs (95% CI) for a ≥5- and ≥10-dB elevation of hearing thresholds at 4 kHz were 2.97 (1.50, 5.89) and 2.79 (1.38, 5.65), respectively. The risk was elevated even among women with tinnitus who had clinically normal hearing thresholds at baseline. In analyses that examined the association of tinnitus and elevation of low-, mid- and high-frequency pure-tone average (PTA) hearing thresholds, the results were similar. Compared with women without tinnitus, the MVORs (95% CI) for ≥5-dB PTA elevation among women with persistent tinnitus were 1.29 (0.99,1.67) for LPTA(0.5,1,2 kHz); 1.44 (1.16, 1.78) for MPTA(3,4 kHz); and 1.38 (1.11, 1.71) for HPTA(6,8 kHz). For ≥10-dB elevation, the MVORs were 2.85 (1.55, 5.23), 1.52 (1.10, 2.09), and 1.41 (1.10, 1.82), respectively.ConclusionPersistent tinnitus was associated with substantially higher risk of 3-year hearing threshold elevation, even among women with clinically normal baseline hearing. The magnitudes of the associations were greater among those with bothersome tinnitus. Monitoring hearing sensitivities may be indicated in patients with tinnitus, including those without audiometric evidence of hearing impairment.
