MSP was associated with some altered immune measures at age 14. MSP was strongly related to reduced lung function in current nonsmokers (forced expiratory flow midexpiratory phase [FEF25\u201375%], P = 0.016; FEV1\/FVC, P = 0.009) and increased risk for current asthma (odds ratio [OR], 1.84; 95% confidence interval [CI], 1.16\u20132.92; P = 0.01), current wheeze (OR, 1.77; 95% CI, 1.14\u20132.75; P = 0.011), and exercise-induced wheeze (OR, 2.29; 95% CI, 1.37\u20133.85; P = 0.002), but not for bronchial hyperresponsiveness or atopy.
