Moisture measurements in the homes of participants in a birth-cohort study were evaluated for possible differences between readings on living room and bedroom walls, readings in homes with and without qualitative indications of dampness or disrepair (i.e., visible mold, visible water damage, a musty or moldy odor, or peeling paint), and readings on exterior (perimeter) and interior walls. Bedroom walls were statistically significantly damper than living room walls (p < 0.0001), although measurements were positively correlated across room types (r = 0.58, p < 0.0001); i.e., homes with drier or damper living rooms also tended to have drier or damper bedrooms. Measured moisture increased with the number of qualitative indicators of dampness/disrepair present in a home. Among single indicators, visible mold and musty odor were the most highly correlated with elevated moisture. Perimeter walls were damper than interior walls (p < 0.0001), but interior walls next to bathrooms were not damper than interior walls next to rooms without plumbing. Source
