Abstract

<b><i>Background:</i></b> About twice as many boys as girls undergo growth hormone (GH) therapy in GH deficiency (GHD). However, this sex difference may not correctly reflect a real incidence. <b><i>Objectives:</i></b> We analyzed the evidence of a selection bias whereby more boys seek treatment at short stature clinics. <b><i>Subjects and Methods:</i></b> The present study included 3,902 children who visited 17 short stature clinics with a height SD score of −2 SD or less. The percentage of children who underwent the GH stimulation test was compared between boys and girls, as was the percentage of children ultimately diagnosed with GHD. <b><i>Results:</i></b> The children comprised 2,390 boys (61.3%) and 1,512 girls (38.7%), with a boy:girl ratio of 1.58:1. The percentage of children who underwent the GH stimulation test did not differ between boys (45.7%) and girls (49.8%). Among the children who underwent the GH stimulation test, the percentage diagnosed with GHD did not differ significantly between boys (22.0%) and girls (20.1%). The boy:girl ratio of children diagnosed with GHD was 1.59:1. <b><i>Conclusions:</i></b> The boy:girl ratio of children with short stature (1.58:1) did not differ significantly from that of children diagnosed with GHD (1.59:1). These results indicate that the predominance of boys in GHD does not reflect a real incidence, but rather a selection bias whereby a higher proportion of boys with short stature seek treatment at clinics. This difference arises because parents are more concerned about boys’ height, and because boys reach adult height at an older age.
