húsum með rakagjöf ekki í meira mæli en í
húsinu þar sem ekki var nein rakagjöf.
í danskri rannsókn þótti sýnt að húsasótt
mætti fremur rekja til loftslags innanhúss
en eðli starfa, notkunar tölva, óánægju með
stjómendur eða samstarfsmenn og skorts á
vinnugleði (24).
Álykta má af niðurstöðum þessarar rannsóknar
að fólki líði best í húsum sem loftræst
eru með opnanlegum gluggum, eru án
vélrænnar endumýtingar loftsins og ekki með
rakagjöfum. Húsasótt virðist vera til hér á
landi en ekkert er sagt um algengi hennar.
SUMMARY
A cross sectional study investigating »sick
building syndrome« was carried out in eight
buildings, ten workplaces, with a questionnaire.
The questionnaire was administrated by mail or at
the workplace. The investigations were either done
at request because of complaints or by the initiative
of the researchers.
In houses which were ventilated solely through
the windows, where there was no mechanical
ventilation or humidifiers the workers had the
lowest prevalence of symptoms. In houses with
mechanical ventilation, which, all but one, were
also humidified, there was higher prevalence of
symptoms compared with the naturally ventilated
houses, regardless of the reason for studying the
house. The serum titer for precipitating antibodies
against antigens from humidifiers was not higher
among workers in houses with humidifiers than in
workers from a control house indicating that the
symptoms were neither prevented or caused by the
exposure to humidifiers.
It is concluded that the most »healthy« houses are
those ventilated through the windows, without
recirculation of air and without humidifiers. Sick
building syndrome appears to exist in Iceland, but
the present study does not deal with its prevalence.
