Atopic eczema and domestic water hardness.
The environment plays an important part in the aetiology of atopic eczema, but specific causes are unknown.
Exposure to hard water is thought to be a risk factor for eczema.
We undertook an ecological study of the relation between domestic water hardness and the prevalence of eczema among Nottinghamshire schoolchildren.
Questionnaire details of a 1-year period and lifetime prevalence of eczema were obtained from parents of 4141 randomly selected primary-school children and 3499 secondary-school children in southern Nottinghamshire Geographical information systems were used to link the geographical distribution of eczema prevalence with domestic water-hardness data (four categories).
Adjustment was made for potential confounding by sex, age, socioeconomic status, and access to health care.
Findings Among the primary-school children there was a significant direct relation between both 1-year period and lifetime prevalence of eczema and water hardness, both before and after adjustment for confounders. ... Interpretation : exposure to hard water in their home may increase the risk of eczema in children of primary-school age.
