The anthropometric variables, baseline lung function parameters, and their corresponding growth rates among boys and girls in the three districts are shown in Tables 3a and b.
After adjustment for potential confounding factors, boys in the LPD had significantly higher FEF25 dpy and FEF25e75 dpy than those in the other two districts. They
also had significantly higher FEV1 dpy than boys in the HPD.
A significantly higher FEF25 dpy was also observed in girls in
the LPD, when compared with girls in the HPD.
