Zinc status of asthmatic, prednisone-treated asthmatic, and non-asthmatic children.
To assess interrelationships between asthma, corticosteroid therapy, growth, and zinc status in children, measurements of height, zinc and copper in serum and hair, taste acuity, and dietary intakes of energy, protein, zinc,and copper were analyzed for 29 asthmatic, 11 prednisone-treated asthmatic, and 21 non-asthmatic subjects, 6 to 20 years old. Reduced height attainment was significant only for the prednisone-treated asthmatic group and was not correlated with clinical or dietary indexes of zinc status. Dietary intake data were similar for all three groups; in comparison with the RDAs, daily intakes were adequate for both energy and zinc (80% to 90%), high for protein (185% to 225%), and low for copper (35% to 60%). Results confirmed earlier reports of growth retardation in corticosteroid-treated asthmatics; significant indications that reduced food intake or impaired zinc status played a major part were not evident.
