Implication

Case-control study demonstrates a dose-response link between damp housing and asthma severity in adults, suggesting home remediation reduces respiratory morbidity.

Key Points

To evaluate the association between damp housing and physician-diagnosed asthma, and to determine whether a dose-response relationship exists between dampness severity and asthma severity.
Conducted a case-control study interviewing 102 subjects with physician-diagnosed asthma and 196 age- and sex-matched controls.
Surveyed 222 dwellings (75% of participants) to objectively assess dampness and visible mould growth.
Quantified asthma severity, dwelling dampness, and lung function using forced expiratory volume in one second (FEV1) measurements.
Surveyor-confirmed dampness was present in 58 of 90 (64%) dwellings of asthmatic subjects compared to 54 of 132 (41%) dwellings of controls (adjusted OR 3.03, 95% CI 1.65 to 5.57).
Asthma severity significantly correlated with measures of total dampness (r = 0.30, p = 0.006) and mould growth (r = 0.23, p = 0.035) in the home.
Residents of damp dwellings showed greater airflow obstruction than those in dry homes (mean difference in FEV1 10.6%, 95% CI 1.0 to 20.3).
