Long-Term Effects of Methylphenidate Transdermal Delivery System Treatment of ADHD on Growth
Abstract
Objective To examine the long-term effects of the methylphenidate transdermal system (MTS) on the growth of children being treated for attention-deficit/hyperactivity disorder.Method Height, weight, and body mass index (BMI) were measured in 127 children ages 6 to 12 at longitudinal assessments for up to 36 months of treatment with MTS. These data were compared with norms provided by the Centers for Disease Control and Prevention.Results MTS treatment was associated with small but significant delays in growth for height, weight, and BMI. The latter two indices were affected in a dose-dependent manner. Children who had not received prior stimulant therapy and children who entered the study with above-average height, weight, and BMI were most likely to experience growth deficits during the trial. Effects on all parameters of growth were most apparent during the first year of treatment, and attenuated over time.Conclusions Consistent with prior studies of methylphenidate, our results suggest that treatment with MTS can lead to reductions in expected height, weight, and BMI that show some attenuation over the course of treatment. Growth of patients with attention-deficit/hyperactivity disorder treated with MTS should be closely monitored, but in this study, deficits in growth in relation to MTS treatment were not a significant clinical concern for most children.

Current data indicate that the initial effect of stimulants on growth appears to attenuate over time, and early studies of adult outcomes of children treated with stimulant medications have suggested that final adult height is not affected.
“Current data indicate that the initial effect of stimulants on growth appears to attenuate over time [39, 114, 139] and early studies of the adult outcomes of children treated with stimulant medications have suggested that final adult height is not affected [55, 71].”

The reduction in weight gain from stimulant treatment appears to be somewhat more pronounced than that for height (over a 3-year period about 3 kg less than predicted).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
