CHEARS: Conservation of Hearing Study
If you are interested in completing the questionnaire, we would like to welcome you into the CHEARS Study and we would be extremely grateful for your participation. Your participation will help us identify risk factors for hearing loss. We need to include women who do not have hearing loss as well as those who do.

What is CHEARS?
We are a research team of physicians, clinical investigators, and audiologists studying the epidemiology of acquired hearing loss, with a specific focus on potentially modifiable risk factors. Our research is supported by the National Institute for Deafness and Other Communication Disorders (NIDCD) and the National Institutes of Health (NIH). Most of our work is based on data collected from three major ongoing cohort studies that include over 250,000 participants: the Nurses' Health Study I (NHS I), the Nurses' Health Study II (NHS II) and the Health Professionals Follow-Up Study (HPFS). We will examine the association between a number of medical, dietary, and lifestyle factors and hearing loss. We will collect information from Hearing Study Supplemental Questionnaires and, in a subset of NHS II participants, from Audiologic Assessments performed by certified clinical audiologists.
