Teen hearing loss rate worsens
SENSORY DEPRIVATION: a new study finds Nearly one in five U.S. adolescents has
measurable hearing damage.
The prevalence of hearing loss in teenagers rose by nearly one-third in recent
years compared with the rate in the 1980s and 1990s, a new study shows. The
findings come as a surprise to the study’s authors, who had expected overall
hearing to improve thanks to publicity about the risks of exposure to loud music
and the advent of childhood vaccines against meningitis and pneumonia that can
prevent many ear infections.
But in the August 18 Journal of the American Medical Association, the scientists
report that the portion of U.S. adolescents aged 12 to 19 with any hearing loss
rose from 14.9 percent during the 1988 to 1995 period to 19.5 percent in 2005
and 2006.
Researchers based the analysis on information gathered from nearly 3,000 kids in
the earlier time frame and more than 1,700 in the later sampling. The findings
suggest that as many as 6.5 million teens in the United States now have some
hearing loss. Written by Nathan Seppa —

Zinc helps prevent pneumonia in the elderly
A new report published in the American Journal of Clinical Nutrition has found
that zinc plays a very important role in health maintenance. In a study of over
600 seniors from 33 different nursing homes in the Boston area, researchers
found that seniors with healthy blood levels of zinc are 50 percent less likely
to develop pneumonia than those with sub-par levels.
The study was a follow-up to a previous one which found that people given 200
international units (IU) of vitamin E every day for one year are 20 percent less
likely to develop upper respiratory infections, including common colds. But
after a follow-up, the trial also revealed that a majority of those same
participants had low levels of zinc in their blood...Natural News; written by
