Several　studies　suggested　significant　associations　of　residential　damp　indicators　with　asthma,　rhinitis,　and　eczema　in　childhood,　but　evidences　of　these　associations　were　not　comprehensively　reviewed　among　previous　studies　in　recent　years.　In　this　paper,　we　systematically　reviewed　and　meta-analyzed　these　studies　to　summary　the　state-of-the-art　findings　on　associations　of　residential　damp　indicators　with　asthma,　rhinitis,　and　eczema　in　childhood.　A　total　of　1579　documents　were　collected　from　five　database　platforms　(two　English,　three　Chinese)　and　56　original　articles　were　finally　retained.　Most　of　these　studies　were　conducted　in　China　during　2010–2023.　All　meta-analyses　among　these　studies　for　different　damp　indicators　(visible　mold　spots,　moldy　odor,　visible　damp　stains,　water　damage,　window　pane　condensation,　and　damp　clothing/bedding)　suggested　significant,　consistent,　and　positive　associations　of　these　indicators　with　the　target　diseases　in　childhood.　Specifically,　the　meta-analyses　indicate　that　the　increased　risks　of　these　damp　indicators　ranged　19　%–54　%　for　ever-doctor-diagnosed　asthma,　27　%–44　%　for　ever-reported　wheeze,　32　%–57　%　for　current-reported　wheeze,　13　%–34　%　for　ever-doctor-diagnosed　rhinitis,　10　%–15　%　for　ever-reported　rhinitis,　15　%–32　%　for　current-reported　rhinitis,　13　%–51　%　for　ever-reported　eczema,　24　%–38　%　for　current-reported　eczema.　Herein,　moldy　odor　generally　increased　the　highest　risks　of　these　diseases,　following　by　visible　mold　spots,　water　damage,　visible　damp　stains,　damp　clothing/beddings,　and　window　pane　condensation.　Our　meta-analyses　furtherly　confirmed　that　residential　dampness-related　exposures　are　risk　factors　for　asthma,　wheeze,　rhinitis,　and　eczema　in　childhood.　More　attention　should　be　paid　on　the　decreases　of　residential　damp　exposures　for　the　prevention　of　these　diseases.　©　2024　Elsevier　Ltd
