Table 2– Logistic regression: risk factors for asthma at a mean age of 6.5 yrs

	Subjects	Crude	Multivariate
Age ≥3 months at admission	64	2.31 (0.91–5.85)	2.04 (0.69–6.04)
Male sex	86	2.03 (0.77–5.32)	2.01 (0.64–6.29)
Atopic dermatitis at <12 months of age	49	8.16 (2.94–22.7)	7.45 (2.45–22.89)
Non-RSV bronchiolitis	50	4.04 (1.57–10.36)	3.74 (1.28–10.99)
Maternal history of asthma	24	4.96 (1.78–13.79)	3.39 (1.03–11.24)

Data are presented as n or odds ratio (95% confidence interval). n=166. Multivariate analyses were performed and adjusted for age on admission, sex, atopic dermatitis in infancy, viral aetiology of bronchiolitis and maternal asthma. RSV: respiratory syncytial virus.
