“…Malnutrition is a substantial, but largely preventable complication for children and adolescents with CF. As malnutrition is recognised as a key factor that adversely affects lung function (Thomson et al, 1995;Steinkamp & Weidemann, 2002) and ultimately survival in those with CF (Corey et al, 1988), nutritional care is considered a major component of CF management (Borowitz et al, 2002). Nutritional status can be assessed by numerous body composition techniques, including skinfolds, bioelectrical impedance and total body potassium, but many of the available techniques have limitations that render them inappropriate for use in children and adolescents with CF (Lands et al, 1993;Stapleton et al, 2001).…”
