Hearing Loss Risk In Men Can Be Reduced By Higher Folates, Not Antioxidants

ncreased intakes of antioxidant vitamins have no bearing on whether or not a man will develop hearing loss, but higher folate intake can decrease his risk by 20 percent, according to new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA.

The study, which identified 3,559 cases of men with hearing loss, found that there was no beneficial association with increased intakes of antioxidant vitamins such as C, E, and beta carotene. However, the authors found that men over the age of 60 who have a high intake of foods and supplement high in folates have a 20 percent decrease in risk of developing hearing loss.

Hearing loss is the most common sensory disorder in the United States, affecting more than 36 million people. High folate foods include leafy vegetables such as spinach, asparagus, turnip greens, lettuces, dried or fresh beans and peas, fortified cereal products, sunflower seeds and certain other fruits and vegetables are rich sources of folate. Baker's yeast, liver and liver products also contain high amounts of folate.

The authors believe this is the largest study to delve prospectively into the relation between dietary intake and hearing loss. They used the most recent figures from the Health Professionals Follow-up Study cohort from years 1986 to 2004, a group consisting of 51,529 male health professionals. They were first enrolled into this study in 1986 and filled out detailed health and diet questionnaires every other year. The authors believe their findings can allow greater education, prevention, and screening efforts.

Noise-Induced Hearing Loss Nearly 3 Times As Likely To Occur In Men

A comprehensive study of the prevalence and risk factors for noise-induced hearing loss (NIHL) show that men, especially those who are white and married, are significantly more at risk than women, according to new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA.
The study, which analyzed the audiometric testing data from 5,290 people between the ages of 20 and 69 years indicates that more than 13 percent of subjects suffer from NIHL, which would correspond with approximately 24 million Americans suffering from the ailment. The strongest association was of gender, where men are 2.5 times more likely to develop NIHL than women. Among that group, married white (non-Hispanic) men represent the highest risk group for developing NIHL.

NIHL is a preventable and increasingly prevalent disorder that results from exposure to high-intensity sound, especially over a long period of time.

The authors believe this is the first study of its kind to delve in to the demographics of NIHL using the most recent figures from 1999-2004 National Health and Nutrition Examination Surveys (NHANES). They believe this information can allow greater education, preventative, and screening efforts.
