| Wheeze OR (95% CI) | Active asthma OR (95% CI) | |
| Maternal asthma | 3.1 (1.8–5.3)§ | 5.6 (2.8–11.1)§ |
| Paternal asthma | 3.9 (2.1–7.3)§ | 3.6 (1.6–7.9)§ |
| Bronchiolitis aged <2 yrs | 5.4 (2.9–9.9)§ | 18.1 (9.1–36.0)§ |
| Any positive SPT | 2.7 (1.8–4.1)§ | 6.3 (3.4–11.8)§ |
| Humid household | 1.5 (1.1–2.1)ƒ | 2.2 (1.3–3.8)ƒ |
| Maternal smoking | 1.2 (0.9–1.7) | 1.1 (0.6–2.0) |
| Born before term | 1.4 (0.8–2.3) | 0.7 (0.3–1.8) |
| Maternal schooling duration¶ | 0.98 (0.92–1.0) | 0.9 (0.8–0.9)## |
| ≥2 siblings | 1.1 (0.8–1.5) | 0.5 (0.3–0.9)## |
| High-load+ Ascaris | 1.8 (0.98–3.4) | 2.4 (1.0–6.1)## |
The total number of subjects included in the two multivariate logistic regression analyses was 954. OR: odds ratio; CI: confidence interval; SPT: skin-prick test. #: adjusted for age and sex; ¶: continuous variable of total duration of maternal schooling used in this specific analysis; +: ≥100 eggs·g−1; §: p≤0.001; ƒ: p≤0.01; ##: p≤0.05.
