Do Healthier Lifestyles Explain Reduced Incidence of Macular Degeneration?

January 14, 2011

Over the last 20 years, the prevalence of age-related macular degeneration fell from 9.4% to 6.5% among adults ages 40 and older,  according to a newly published study in the Archives of Ophthalmology.  Data from the 2005-2008  and 1988-1994 NHANES studies were compared.

The researchers wrote that, “The decreasing prevalence of AMD may reflect recent changes in the frequency of smoking and other exposures such as diet, physical activity, and blood pressure associated with AMD.”

Further declines may be seen in the future, and will depend on the effectiveness of programs that educate aging individuals as to the importance of the above lifestyle factors in preventing the disease.
