Health Relevant Outdoor Air Change Rates in Homes

February 6, 2003 - 12:00pm
Bldg. 90

The Damp Building and Health (DBH) study started as a cross-sectional questionnaire study of all 14000 children, 1-6 years of age in Värmland, Sweden. The response rate on the questionnaire (year 2001) was 79%, meaning that basic data exists on almost 12,000 children and their homes. In a second step a case-control study on 200 sick (wheezing, asthma, excema), and 200 healthy children, extensive measurements in the home, as well as clinical examinations of the children has been conducted during 2002. Ventilation has been measured with a passive tracer gas method during one week. The results will be presented in this seminar-- seemingly sick children have a lower ventilation rate in their homes.
