Home/Housing

Many studies have shown consistent associations between evident indoor dampness or mold and respiratory or allergic health effects, but causal links remain unclear. Findings on measured microbiologic factors have received little review. We conducted an updated, comprehensive review on these topics. The review indicated that evident dampness or mold had consistent positive associations with multiple allergic and respiratory effects. Measured microbiologic agents in dust had limited suggestive associations, including both positive and negative associations for some agents. Thus, prevention and remediation of indoor dampness and mold are likely to reduce health risks, but current evidence does not support measuring specific indoor microbiologic factors to guide health-protective actions.

The Minnesota Department of Health has created a free home environmental assessment training, named Reducing Environmental Triggers of Asthma–Home, or RETA-Home. This program teaches you about the triggers of asthma found in the home and suggests simple interventions that can limit or eliminate exposure to them. It also tours a home to show areas where asthma triggers are found. The training takes about 40 minutes to view. It includes pre- and post-test questions that highlight important points, and you may print out a certificate of completion at the end. In addition, there is a resource section that can be accessed both during the program and after the program has been completed.

This training utilizes the expertise of individuals who have extensive experience in both providing in-home asthma management and conducting home assessments. It builds on data from projects showing that environmental interventions, coupled with in-home asthma medical management, are effective in reducing nighttime symptoms, missed school days, and the number of asthma hospital visits and unscheduled, urgent care office visits.

This training program was made possible from grants from EPA Region V and CDC.
