All subjects in EDIC and approximately 10 non-diabetic control subjects will be recruited to participate in the hearing impairment ancillary study. This will include assessment of hearing status by questionnaires and evaluation by a local licensed audiologist. EDIC study staff will obtain institutional regulatory board approval, document participant informed consent, administer questionnaires, and make all arrangements for the study visit and audiologic evaluation. Control subjects will have laboratory assessments for hemoglobin Alc to verify non-diabetic status. The EpiSense Audiometry Reading (EAR) Center at the University of Wisconsin will perform certification protocols with your institutional audiologists prior to data collection from research subjects. The EAR Center will receive all the audiograms from EDIC Centers for expert interpretation. Questionnaire data will be entered by local EDIC staff into the web-based MIDAS data collection system overseen by the EDIC Data Coordinating Center at George Washington University (GWU). GWU will merge your data with data from the other EDIC Centers. The EAR Reading Center and the Data Coordinating Center will perform statistical analyses of the data from all EDIC Centers and prepare manuscripts.
