Insufficient evidence for other ills,

WASHINGTON (AP) -- Respiratory
problems, including some asthma, can be caused by mold, but an extensive
study released Tuesday failed to indict the fungus for a host of other,
often major illnesses that some have sought to associate with it.
"Even though the available evidence
does not link mold or other factors associated with building moisture to
all the serious health problems that some attribute to them, excessive
indoor dampness is a widespread problem that warrants action at the local,
state and national levels," said Noreen Clark, dean of the
School of Public Health at the University of Michigan.
Clark
headed an Institute of Medicine panel that studied the health effects of
mold, which has drawn increased attention in recent years with the
shutdown of a major hotel, delayed openings of schools in several states
and a raft of lawsuits.
The Institute, an arm of the
National Academy of Sciences, said mold and building dampness do
constitute a problem and urged it be corrected through a range of steps,
including changes in how buildings are designed,constructed and
maintained.
"An exhaustive review of the
scientific literature made it clear to us that it can be very hard to
tease apart the health effects of exposure to mold from all the other
factors that may be influencing health in the typical indoor environment,"
said
Clark.
"That said, we were able to find
sufficient evidence that certain respiratory problems, including symptoms
in asthmatics who are sensitive to mold, are associated with exposure to
mold and damp conditions," she concluded.
Excessive dampness influences
whether mold, as well as bacteria, dust mites and other such agents, are
present and thrive indoors, the committee noted. In addition, the wetness
may cause chemicals and particles to be released from building materials.
A rare ailment known as
hypersensitivity pneumonitis also was associated with indoor mold exposure
in susceptible people.
But the committee said it was unable
to find evidence that mold is associated with fatigue, neuropsychiatric
disorders or other health problems that some people have attributed to
fungal infestations of buildings.
The little evidence that is
available does not support an association, the committee said, but it
added that because there are so few studies it cannot rule out a
connection.
Molds that are capable of producing
toxins do grow indoors, and toxic and inflammatory effects also can be
caused by bacteria that flourish in damp conditions, the report noted.
The committee said information
exists on how to control dampness but architects, engineers, building
contractors, facility managers and maintenance staff do not always apply
this knowledge.
The members called for development
of guidelines for preventing indoor dampness and said they should be
promoted nationally. In addition, building codes and regulations should be
reviewed and modified as necessary to reduce moisture problems, the
committee said.
Lawsuits claiming illnesses from
mold in buildings that were not properly built or cleaned up have
multiplied in recent years.
Changes in building codes in the
1970s to make homes more energy efficient and airtight had the effect of
allowing less ventilation through a house that would dry out a wet wall or
floor, which in turn may have led to more mold damage claims, according to
attorneys involved in some cases.
The National Academy of Sciences is
a private institution chartered by Congress to advise the government on
scientific matters. The study was funded by the federal Centers for
Disease Control and Prevention.
