Several epidemiological studies have reported a higher prevalence of respiratory symptoms in subjects living in damp housing, but links with specific respiratory diseases such as asthma have not been satisfactorily established.

The prevalence of both self-reported and observed dampness in the homes of the asthmatic subjects and controls were compared. Both asthma and the severity of the dampness were quantified so that the possibility of a dose-response relationship could be investigated.

Asthmatic subjects reported dampness in their current odds ratio OR 1. This association persisted after controlling for socioeconomic and other confounding variables adjusted OR 3.

Patients living in homes with confirmed areas of dampness had greater evidence of airflow obstruction than those living in dry homes mean difference in forced expiratory volume in one second FEV1 Asthma is associated with living in damp housing and there appears to be a dose-response relationship.

Action to improve damp housing conditions may therefore favourably influence asthma morbidity. Selected References These references are in PubMed.

This was a hospital based case-control study using routine postcoded regional Hospital Episode Statistics for children aged 5–14 years living in the North Thames (West) health region within the boundary of London's orbital M25 motorway.

A population based case control-study was initiated in to identify risk factors for death from asthma. Over a two year period all deaths in the Auckland population possibly due to asthma, in people less than 60 years of age, were investigated.

From the 47 people who died from asthma 44 who had useful reversibility of airways obstruction (records showing greater than 20% variability of.
