Milanzi EB, et al. - Researchers examined the associations of air pollution exposure with forced expiratory volume in 1 s (FEV₁) and forced vital capacity (FVC) growth from ages 8 to 16 and FEV₁ and FVC at age 16, both longitudinally (N=915) and cross-sectionally (N=721). They observed reduced FEV₁ growth, and lower FEV₁, in relation to higher air pollution exposure. No adverse association of higher air pollution exposure with FVC was noted. Boys vs girls showed stronger associations with FEV₁ and these links were not modified by asthma status. Overall, they concluded that, increased airway obstruction, but not reduced lung volume, may be seen in adolescence as a consequence of higher air pollution exposure.
