Abstract

Objectives To compare laboratory test results and lung function of adolescent organised sports participants (SP) with non-participants (NP).Methods In this cross-sectional study, laboratory tests (haemoglobin, iron status), and flow-volume spirometry were performed on SP youths (199 boys, 203 girls) and their NP peers (62 boys, 114 girls) aged 14textendash17.Results Haemoglobin concentration lt;120/130~g/L was found in 5.8.1OR 1.20, 95.54 to 2.68). Ferritin concentration below 15~textmug/L was found in 22.7% of both SP and NP girls. Among boys ferritin lt;30~textmug/L was found in 26.50.2OR 0.76, 95.40 to 1.47). Among SP iron supplement use was reported by 3.5.5volume spirometry with bronchodilation test, 7.0.4like findings (OR 1.17, 95.54 to 2.54); those using asthma medication, that is, 9.8.2% of NP were excluded from the analysis.Conclusions Screening for iron deficiency is recommended for symptomatic persons and persons engaging in sports. Lung function testing is recommended for symptomatic persons and persons participating in sports in which asthma is more prevalent.
