Hearing loss, tinnitus, and balance dysfunction are common age-related issues. However, cohort studies of hearing have been primarily limited to Caucasian populations. The Jackson Heart Study (JHS) is a longitudinal cohort study of 5,301 African Americans living in the metropolitan Jackson, MS area with a focus on cardiovascular/cardiometabolic health. The JHS Hearing Ancillary Study was implemented to measure the prevalence of hearing, tinnitus, and balance outcomes and relationship to predictor variables. Hearing thresholds were measured with standardized protocols using pure-tone air and bone-conduction audiometry in a sound-treated booth. The examination also included otoscopic evaluation, tympanometry, speech audiometry, and tests of central auditory processing. Questionnaires on hearing-related health, noise exposure, tinnitus, self-perceived hearing handicap, and balance were completed. Of the total 5,301 JHS participants, nearly 2,000 individuals participated in the JHS-HS, with 1,314 (24.7%) participants meeting inclusion criteria.
We are currently in the process of analyzing our data and preparing a grant to examine longitudinal outcomes. For information on collaboration or data access, contact firstname.lastname@example.org
