Does Dampness and Mold in Schools Affect Health? Results of a Meta-Analysis

This research presents the results of a meta-analysis that quantifies the relationship between dampness or mold in schools and respiratory health symptoms among occupants. Drawing on 11 previous studies, the authors found statistically significant associations between damp or moldy school environments and increased prevalence of respiratory symptoms in children and staff. Specifically, the analysis estimates a 32% increase in the odds of developing respiratory symptoms and a 59% increase in the odds of experiencing wheeze when exposed to dampness or visible mold in school buildings. These findings are consistent across diverse geographical locations and age groups and offer strong evidence that inadequate moisture control in schools has measurable health consequences.
The study emphasizes the importance of preventing and promptly addressing moisture problems and mold growth through building design, maintenance, and operations practices. It notes that effective strategies to prevent dampness include controlling leaks, maintaining indoor humidity levels, using proper HVAC systems, and ensuring building envelopes are sealed and maintained. While the paper focuses on health outcomes rather than academic performance, it underscores the need for facility managers, school officials, and public health professionals to prioritize moisture and mold prevention as part of a comprehensive indoor environmental quality strategy.
This resource is particularly valuable for those seeking quantitative evidence to support mold remediation programs and for advocating capital or operational investments in school building maintenance. It provides a clear, research-backed case that controlling dampness is not only a facilities concern but a critical health protection measure.
