Aim To investigate the independent relationships between baseline characteristics and incident wheeze in adolescents, with particular regard to gender. Methods Adolescents (N = 959), aged 12‐15 years, answered a standardised respiratory questionnaire and underwent height and weight measurements at baseline. Four years later, 96% of the subjects completed a similar questionnaire. The present study included the adolescents without self‐reported wheeze at baseline (n = 795; 394 girls). Results The proportion of adolescents with obesity was higher among subjects with incident wheeze than among subjects who never reported wheeze: 19.1% vs 8.3%. When stratifying for gender, this difference was only found in girls. In stepwise logistic regression models (odds ratios [95% confidence interval]), obesity (2.84 [1.17‐6.86]) and rhinitis (3.04 [1.53‐6.03]) at baseline and current smoking (2.60 [1.16‐5.82]) at follow‐up were associated with incident wheeze in girls. For boys, FEV 1 <−1.65 standard deviation (3.20 [1.04‐9.79]), family asthma (3.16 [1.46‐6.86]) and seasonal allergic symptoms (5.61 [2.56‐12.27]) at baseline were independently associated with incident wheeze. Conclusion Data stratified by gender showed that obesity in girls and an atopic constitution in boys were independently associated with increased risk of developing wheeze within four years.
