Current asthma	1.90 1.09-3.32	0.84 0.28-2.57	1.57 1.00-2.48
Current wheeze	1.16 0.66-2.02	0.83 0.31-2.22	1.08 0.69-1.70
Physician-diagnosed rhinitis	1.21 0.73-2.00	0.32 0.04-2.39	1.05 0.68-1.61
Current rhinitis	1.21 0.76-1.91	1.62 0.93-2.82	1.29 0.94-1.77
Physician-diagnosed eczema	1.19 0.72-1.99	0.74 0.37-1.47	1.01 0.69-1.48

The analyses have been adjusted for sex, parental asthma, parental smoking and damp housing. The exposure variable was currently attending indoor swimming pools ≥1/week.

Risk estimates express as Odds Ratios (OR) with 95% confidence intervals (CI). Data are presented separately for all children in the study population and the children in the study population by sensitization status.
