Progressive and permanent sensorineural hearing loss associated with noise exposure (NIHL) is a chronic health condition in agricultural workers.  In addition to the impact of hearing loss on communication, hearing loss and exposure to noise have negative impacts on balance, cardiovascular health, mental health, and cognitive skills.  Recent large-scale public health studies among elderly and middle-aged persons indicated hearing loss presents a significant and independent risk factor for the development of dementia.  This project will examine the hearing status and cognitive skills of aging farmers and ranchers over the age of 50.  Audiological assessment and a hearing health history will be obtained for each participant.  Pure tone average and Speech Intelligibility Index will be computed.  Due to the fact that agricultural workers often have concomitant hearing loss, the memory and cognitive processing tests used for this study will assess cognitive status through the visual and visual-motor domains.  The following screening tests are proposed for the first phase of this study:  The Montreal Cognitive Assessment (MOCA), Stroop Color and Word Test (STROOP) and the Digit Symbol Digit Symbol Substitution Test (DSS).  The data obtained will provide new information regarding the impact of long-term hearing loss on cognition in older agricultural workers, and also provide a foundation of knowledge for longitudinal studies.
