This study was reported in The Medical Journal of Australia,1/22/13. It looked at both height and pubertal attainment (love the scientific term!) for boys between the ages of 7 to 15.99. As has been suspected in the past (the conclusion claims this is the first study to confirm) stimulant medicines used for ADHD stunts height in boys but doesn’t delay puberty. It is still unclear if the boys “catch up” with their height.
