Recent cross-sectional studies of children with cystic fibrosis (CF) have shown an improvement in their growth with improved nutritional status, but there are only a few longitudinal studies in this population. A four-year prospective study was conducted in 25 children with CF and 26 controls, ages 5 to 10 years at baseline, to describe changes in body composition using three independent methods of assessment: skinfold thickness, total body water by deuterium dilution, and total body electrical conductivity (TOBEC). The statural growth of the boys with CF was slower than that of the control boys. Using different methods, the fat-free mass and fat-mass increases were shown to be slower in boys with CF than in controls. These differences were less significant in girls. Despite comprehensive care, the growth of boys with CF may still not be optimal, as observed longitudinally.

D003550 Cystic Fibrosis An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
