The authors conducted a population-based incident case-control study to assess the relations between different types of interior surface materials and recent renovations at home and at work and the risk of asthma in adults. The authors systematically recruited all new cases of asthma during a 2.5-year study period (1997-2000) and randomly selected controls from a source population consisting of adults 21-63 years of age living in south Finland. ⋯ Use of floor-leveling plaster at home during the past 12 months was also a determinant of onset of asthma (adjusted OR = 1.81, 95% CI: 1.06, 3.08). These findings underline the need to consider the health aspects of materials used in floor, wall, and other indoor surfaces.
