SAN DIEGO—Higher dietary intakes of vitamin C and certain other antioxidants are associated with decreased progression of lower urinary tract symptoms (LUTS) in elderly men, according to a study presented at the American Urological Association 2013 annual meeting.
The study by Kathleen Holton, PhD, MPH, of Oregon Health and Science University in Portland, and colleagues included 786 male participants in the MrOS study, which from 2000 to 2002 enrolled 5,994 men aged 65 years and older. The cohort included 341 men with LUTS progression and 445 with stable symptoms over approximately seven years.
Compared with men in the lowest quartile of dietary vitamin C intake, those in the highest quartile had a 46% decreased risk of LUTS progression. Men in the highest quartile of lutein/zeaxanthin and beta-cryptoxanthin intake had a 42% and 31% decreased risk of progression, respectively, compared with those in the lowest quartile.
The researchers concluded that diets rich in these antioxidants (such as green leafy vegetables, sweet peppers, citrus fruits, and pumpkin) may be important for the prevention of LUTS progress, the authors concluded.
