Objectives: To evaluate the relationships among the overall cardiovascular health scoring tool, Life's Simple 7 (LS7), and hearing in an African-American cardiovascular study cohort., Methods: Using the Jackson Heart Study's cohort of African Americans, the relationships between the LS7 scoring metric and hearing of 1314 individuals were assessed. Standard audiometric data was collected and hearing loss was defined as a four-frequency average of 500, 1000, 2000, and 4000 Hz greater than 25 dBHL (PTA4). Measures of reported tinnitus and dizziness were also collected. The LS7 scoring tool, which consists of seven individual categories (abstinence from smoking, body mass index, physical activity, healthy diet, total cholesterol <200 mg/dL, normotension, and absence of diabetes mellitus), was used as measure of overall cardiovascular health. Each category of the LS7 was broken down into poor, intermediate, and ideal subgroups as in accordance with the American Heart Association Strategic Planning Task Force and Statistics Committee. Unadjusted and adjusted gamma regression and logistic regression models were constructed for determining relationships between LS7 and hearing loss., Results: Higher total LS7 scores (per 1-unit increase) were associated with lower PTA4 in gamma regression analyses (RR = 0.942, 95% CI, 0.926-0.958, P < .001). This held true even after adjustments for age, sex, education, and history of noise exposure. Using logistic regression analyses to compare LS7 scores to presence of hearing loss, tinnitus, and vertigo; only hearing loss showed a statically significant relationship after adjustments for age, sex, education, and history of noise exposure., Conclusions: This study shows a significant, graded association between higher life's simple seven scores and lower incidence of hearing loss., Level of Evidence: 2b.

Objectives/hypothesis: The objective of this study was to determine the audiological profile of an African American cohort, identify related factors, and compare them to other datasets., Study Design: Cross-sectional, longitudinal cohort study., Methods: The Jackson Heart Study (JHS) is a longitudinal cohort study of 5,306 African Americans living in the metropolitan Jackson, Mississippi area, with a focus on cardiometabolic health. The JHS Hearing Study (n = 1,314) was implemented to measure the prevalence of hearing, tinnitus, and balance outcomes and relationship to predictor variables. Here we present prevalence and covariate relationships in comparison to the Epidemiology of Hearing Loss Study and the National Health and Nutrition Examination Survey., Results: The prevalence of self-reported hearing difficulty was 38.1% (n = 500). The prevalence of hearing loss based on audiometric pure tone threshold average (0.5, 1.0, 2.0, 4.0 kHz) of the better ear was 19.8% (n = 260) and for the worse ear 29.8% (n = 392). The prevalence of tinnitus was 29.5% (n = 388) and balance dysfunction 24.1% (n = 317). Relationships of hearing loss to demographic, cardiometabolic, and audiologic variables are presented., Conclusions: These results demonstrate that hearing loss, tinnitus, and balance dysfunction are common issues affecting adult African Americans, and that hearing loss is related to numerous modifiable and nonmodifiable risk factors. Furthermore, our findings are consistent with lower prevalence of hearing loss in African Americans compared to the non-African American populations. However, despite the lower audiometric evidence of hearing loss, nearly 40% of participants reported hearing difficulty., Level of Evidence: 2b Laryngoscope, 129:2391-2397, 2019., (© 2019 The American Laryngological, Rhinological and Otological Society, Inc.)

Objectives: There is limited research in population-based studies on auditory processing. The purpose of this work is to determine the prevalence of auditory processing impairment in the Jackson Heart Study cohort and to identify potential relationships with cardiometabolic risk factors., Study Design: Cross-sectional study., Setting: Jackson Heart Study in Jackson, Mississippi., Subjects: Participants of an all-African American cardiovascular study cohort (n = 1314)., Methods: The Quick Speech-in-Noise and Dichotic Digits, Double Pairs tests were used to assess auditory processing. Logistic regression and multinomial logistic regression models were used to examine how participants' cardiometabolic risk factors and audiologic characteristics were associated with speech perception in noise and binaural integration., Results: Quick Speech-in-Noise and Dichotic Digits, Double Pairs testing showed a prevalence of auditory processing impairment in 69% and 71% of the cohort, respectively, which was significantly related to age, hearing thresholds, sex, and education level. With covariate adjustment in statistical models for age, sex, pure tone average, and education level, waist circumference, systolic blood pressure, and hypertension were statistically predictive of auditory processing impairment ( P < .05)., Conclusion: The results suggest a high prevalence of auditory processing deficits in the Jackson Heart Study cohort. In addition, cardiometabolic and audiologic factors show a statistically significant independent relationship with auditory impairment measures.

Objectives/hypothesis: To describe the prevalence of reported tinnitus and tinnitus handicap in the all-African American Jackson Heart Study (JHS) cohort, with assessment of the relationship to cardiometabolic risk and depression., Study Design: Prospective cohort study., Methods: Audiologic data were obtained from a sample of 1,314 participants of the JHS. Reported tinnitus was assessed dichotomously (yes/no) by interview and with the Tinnitus Handicap Inventory (THI). The statistical relationship of reported tinnitus and tinnitus handicap to various cardiometabolic risks (i.e., hypertension and waist circumference) and Center for Epidemiologic Studies Depression scale (CES-D) was assessed with logistic and gamma regression procedures., Results: Tinnitus was found to be a highly prevalent condition (29.5%), with an additionally high rate of individuals who report at least slight tinnitus handicap (35%). Hypertension (β = 1.344, 95% confidence interval [CI]: 1.015-1.780, P = .039) and waist circumference (β = 1.009, 95% CI: 1.001-1.018, P = .021) were found to have a statistically significant relationship with THI score, depending on the level of covariate adjustment. Depression, as measured by the CES-D, was found to have a statistically significant relationship with both reported tinnitus (odds ratio [OR]: 1.051, 95% CI: 1.030-1.072, P < .001) and THI score (β = 1.029, 95% CI: 1.013-1.047, P = .001), which persisted for all levels of covariate adjustment in statistical models., Conclusions: Tinnitus was found to be highly prevalent in the JHS, and certain measures of cardiometabolic risk are weakly related to both reported tinnitus and level of tinnitus handicap. A consistent relationship between depression and tinnitus/level of tinnitus handicap was observed., Level of Evidence: 2b.
