Effect of supplementary zinc on body mass index, pulmonary function and hospitalization in children with cystic fibrosis.

Zinc deficiency, which is common in patients with cystic fibrosis (CF), can lead to several complications that may increase the number of hospital admissions in this group of patients. As supplementary zinc can prevent such complications, this study was performed to evaluate the effect of supplementary zinc on body mass index (BMI), forced expiratory volume in one second (FEV1) and number of hospitalizations in CF patients. In this study, 30 children with CF, who were referred to the Digestive Diseases Clinic of the Children's Medical Center in Tehran, were enrolled.
