Glucose control linked to hearing loss in women

Researchers at Henry Ford Hospital in Detroit reviewed records for 990 patients who had audiograms performed between 2000 and 2008. 

The research showed that if the diabetes was well controlled, women aged 60–75 years had similar hearing levels to that of women without diabetes of the same age. However, hearing in women with poorly controlled diabetes was significantly worse.
 Hearing in all the women younger than 60 with diabetes was significantly reduced even if the diabetes was well controlled.

Men had worse hearing loss than women, regardless of their age or whether or not they had diabetes.
