Abstract

BACKGROUND AND OBJECTIVE: There is ongoing concern that stimulant medications may adversely affect growth. In a sample of attention-deficit/hyperactivity disorder (ADHD) cases and controls from a population-based birth cohort, we assessed growth and the association between stimulant treatment and growth.

METHODS: Subjects included childhood ADHD cases (N = 340) and controls (N = 680) from a 1976 to 1982 birth cohort (N = 5718). Height and stimulant treatment information were abstracted from medical records and obtained during a prospective, adult follow-up study. For each subject, a parametric penalized spline smoothing method modeled height over time, and the corresponding height velocity was calculated as the first derivative. Peak height velocity (PHV) age and magnitude were estimated from the velocity curves. Among stimulant-treated ADHD cases, we analyzed height Z scores at the beginning, at the end, and 24 months after the end of treatment.

RESULTS: Neither ADHD itself nor treatment with stimulants was associated with differences in magnitude of PHV or final adult height. Among boys treated with stimulants, there was a positive correlation between duration of stimulant usage before PHV and age at PHV (r = 0.21, P = .01). There was no significant correlation between duration of treatment and change in height Z scores (r = −0.08 for beginning vs end change, r = 0.01 for end vs 24 months later change). Among the 59 ADHD cases treated for ≥3 years, there was a clinically insignificant decrease in mean Z score from beginning (0.48) to end (0.33) of treatment (P = .06).

CONCLUSIONS: Our findings suggest that ADHD treatment with stimulant medication is not associated with differences in adult height or significant changes in growth.

  • What’s Known on This Subject:

    Stimulant medications are indicated for treatment of childhood attention-deficit/hyperactivity disorder (ADHD), but there is concern that stimulants may negatively affect growth. However, no longitudinal, population-based studies have examined height into adulthood for childhood ADHD cases.

    What This Study Adds:

    This longitudinal, population-based study shows that neither childhood ADHD itself nor treatment with stimulants is associated with significant deficits in height into adulthood.

    Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed childhood neurodevelopmental disorder.1,2 Treatment with stimulant medication reduces the core symptoms of ADHD and may improve school, social, and behavioral functioning.3–7 However, the chronicity of ADHD7,8 and persistent concerns about the effect of stimulant treatment on growth9,10 necessitate a deeper understanding of how ADHD and stimulant treatment may affect growth.

    ADHD may be associated with dysregulated growth.11–13 Early adolescents with ADHD may have small but significant height deficits compared with controls.14 In contrast, among stimulant-naive patients with ADHD, baseline height may be slightly greater than population norms,9 and children referred for ADHD treatment are reportedly taller at baseline than those not referred.9,15,16 The Multimodal Treatment Study of Children With ADHD Cooperative Group reported that untreated prepubertal children with ADHD had average height Z scores that increased over time, suggesting faster growth than population norms.17 More research is needed to assess associations between ADHD and dysregulated growth.

    The potential adverse effect of stimulants on growth may be due to both their anorexic effect and an increase in synaptic dopamine, which acutely inhibits growth hormone.9,18 Although studies in the 1970s reported reductions in height in children treated with stimulant medication,10,19 subsequent studies have been mixed, with some reporting growth reductions16,20–22 and others finding no significant growth changes.23–26 Higher dosages of stimulants may cause more growth attenuation.9,19,27,28 Growth deficits may differ based on type,9,19,28–30 age of initiation,31–34 or duration16,35,36 of stimulant medications. Specifically, stimulant treatment duration >3 years may be associated with decreased height velocity throughout adolescence.36 Limitations in the existing literature include small sample sizes, lack of controls, referred samples limiting generalizability, and paucity of information about adult growth outcomes.

    In this study, we report on the long-term associations between ADHD case status, stimulant treatment, and height in a large, population-based cohort of adults with childhood ADHD and without childhood ADHD. We compared height velocity, height Z scores before and after stimulant treatment, and adult height for subjects with versus without ADHD and, among ADHD cases, for those treated with stimulants versus those not treated. We examined the effect of stimulant medication by analyzing the impact of duration of stimulant treatment on height-for-age Z scores at the beginning, the end, and 24 months after the end of stimulant treatment.

    Methods

    Study Setting

    The Rochester Epidemiology Project provided the infrastructure for this research.37 Almost all medical care for residents of Rochester, Minnesota is provided by Mayo Clinic, Olmsted Medical Center, and their 3 affiliated hospitals. Through the Rochester Epidemiology Project, all medical diagnoses and surgical procedures are recorded and indexed for computerized retrieval. The medical records contain detailed history of all medical encounters. For this project, all 41 public and private schools in Minnesota Independent School District 535 (Rochester, MN) participated in a contractual research agreement providing access to cumulative educational records for every child in the 1976 to 1982 Rochester, Minnesota birth cohort. The institutional review boards of both Mayo Clinic and Olmsted Medical Center approved this study.

    Subjects

    Birth Cohort

    This study used a birth cohort consisting of all children born between January 1, 1976 and December 31, 1982 to mothers residing in the townships in Minnesota Independent School District 535, who continued to live in Rochester until at least age 5 years and who granted permission for research use of their medical records (N = 5718). The cohort was initially identified through computerized birth certificate information obtained from the Minnesota Department of Health, Division of Vital Statistics.38 The birth certificate information included characteristics of both the child (eg, birth length and weight) and the mother (eg, age and education).

    Identification of Childhood ADHD Cases and Controls

    The identification of childhood ADHD incident cases (N = 379) in this birth cohort has been described elsewhere39 and was based on combinations of the following 3 categories of information from school and medical records: behavioral symptoms consistent with criteria for ADHD from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision; positive ADHD questionnaire results; and documented clinical diagnosis of ADHD. Research ADHD criteria were met at a mean age of 10.4 years. At the time of this study, 340 ADHD cases continued to allow use of their records for research. For each case, we randomly selected 2 age- and gender-matched controls without ADHD (n = 680) from the birth cohort.

    Height Measurements

    This study used both a retrospective phase and a prospective follow-up of subjects into adulthood.2,8 We retrospectively obtained height from medical records for each subject from birth through August 2010. We also prospectively obtained height measurements using a stadiometer during the prospective phase of a research study using this same cohort.8 During the retrospective phase of the study, height measurements were obtained by clinical staff and recorded in inches or centimeters rounded to the nearest 0.5. For our analyses, all measurements were converted to centimeters. During the prospective phase of the study, trained research staff obtained height measurements during study visits from 8 am to 5 pm, to the nearest millimeter, using a Seca stadiometer (Seca Corporation, Issaquah, WA).

    Stimulant Medication Treatment

    In a previous study, we reviewed medical records of all ADHD cases for documentation about stimulant treatment.40 For each documented stimulant treatment episode, we abstracted the dosage and associated start and stop dates, based on the dates of visits at which medications were prescribed and when prescription refills were written. The cumulative duration of stimulant treatment was derived by summating the durations of the individual treatment episodes. ADHD cases were considered “stimulant treated” if treated for a cumulative duration of ≥3 months between 2 and <21 years of age; otherwise they were considered stimulant naive.

    Data Analysis

    Analyses were performed with the SAS version 9.2 software package (SAS Institute, Inc, Cary, NC). All calculated P values were 2-sided; P values <.05 were considered statistically significant. We used standard statistical methods to summarize the data: frequencies and percentages for nominal scaled variables and means and standard deviations or medians and interquartile ranges for continuously scaled variables. Comparisons between groups (ADHD cases versus controls, stimulant treated versus not-treated ADHD cases) were evaluated by using the χ2 test for gender, the 2-sample t test for birth length, birth weight, and age, and the Wilcoxon rank-sum test for maternal education categories and number of height measurements.

    Height Velocity

    Because height was measured during clinic visits, the number of measurements and spacing over time varied by subject. To obtain estimates of height continuously from infancy through early adulthood separately for each subject, we used a parametric penalized spline smoothing method proposed and implemented in MATLAB by Cao, Cai, and Wang41 to model height over time. This method combines the advantages of a parametric growth model based on expert knowledge42 with the flexibility of nonparametric smoothing methods. For each subject, we separately predicted the height and height velocity (by taking the first derivative of the function) from age 0 to 30 years at 0.1 increments. For each subject, we determined the peak height velocity (PHV) based on the point of maximal height velocity during the pubertal growth phase. We used the 2-sample t test (unadjusted for multiple comparisons) to compare the age at PHV and the magnitude of PHV between groups, separately by gender. We estimated the correlation between the cumulative stimulant duration before PHV and the age at PHV by using the Pearson correlation coefficient. To adequately estimate the height velocity continuously throughout the key periods of puberty and stimulant use, we restricted this analysis to use all available height measurements for subjects with ≥1 recorded height measurement during each of 3 following time intervals: 6 to <9, 9 to <12, and 12 to <15 years of age.

    Height Z Scores Before and After Stimulant Treatment

    We determined gender-specific height-for-age Z scores using the 2000 Centers for Disease Control and Prevention growth chart.43 Among the ADHD cases treated with stimulants for ≥3 months, we identified the gender-specific height-for-age Z scores at the beginning, the end, and 24 months after the end of stimulant treatment as follows: The Z score at the beginning of treatment was defined as the closest height within 6 months before or up to 3 months after treatment with stimulants started, the Z score at the end of treatment was defined as the closest height recorded within 3 months before or 3 months after treatment with stimulants ended, and the Z score 24 months after the end of treatment was defined as the closest height at 24 months recorded between 21 and 27 months after treatment with stimulants ended. The relationship between change (post–pre) in Z scores and the total cumulative stimulant duration was depicted graphically as a scatterplot using a loess smoother, and we estimated the correlation by using the Pearson correlation coefficient. We evaluated paired comparisons of Z scores by using the paired t test.

    Adult Height

    We defined adult height as the average of all height measurements performed at age ≥18 years for women and at age ≥20 years for men, consistent with criteria used in other studies.44–46 Adult height was compared between groups, separately by gender, using the 2-sample t test.

    Results

    Characteristics of ADHD Cases and Controls

    Of the 340 ADHD cases and 680 age- and gender-matched non-ADHD controls, 339 cases and 674 controls had ≥2 height measurements recorded. The 339 ADHD cases had a median of 36 (interquartile range, 25–54) height measurements per subject over an average of 26.2 years of follow-up. The 674 controls had a median of 28 (interquartile range, 18–41) height measurements per subject over an average of 23.1 years of follow-up. To adequately estimate the height velocity continuously throughout the key periods of puberty and stimulant treatment, we restricted the cohort to 637 subjects (243 ADHD cases, 394 controls) with ≥1 recorded height measurement during each of following 3 time intervals: 6 to <9, 9 to <12, and 12 to <15 years of age. Table 1 summarizes the baseline and follow-up characteristics of these 637 subjects.

    Among these 243 childhood ADHD cases, 171 (70.4%) were treated with stimulants for ≥3 months (Table 2). ADHD cases were prescribed methylphenidate (N = 152) and dextroamphetamine (N = 70) most commonly. Many ADHD cases (N = 67, 39.2%) were prescribed >1 type of stimulant medication over time.

    Estimated Peak Height Velocity

    For each of the 637 subjects (243 ADHD cases, 394 controls), all recorded height measurements were used to predict their height and height velocity from 0 to 30 years of age using the parametric penalized spline smoothing method. As an example, Fig 1 depicts recorded height measurements, estimated height, derived height velocity, and PHV for 2 non-ADHD subjects. For 77 subjects (26 [10.7%] of ADHD cases and 51 [12.9%] of non-ADHD controls), there was no apparent PHV, based on visual inspection of the velocity curves; therefore, they were excluded from PHV analyses. The mean age at PHV and magnitude of PHV were not significantly different between ADHD cases and non-ADHD controls, either among male or female subjects (Figs 2 and 3, Table 3). There was no statistically significant difference between stimulant-naive ADHD cases at the time of the PHV and non-ADHD controls in age at PHV (male subjects, P = .08; female subjects, P = .41) or magnitude of PHV (male subjects, P = .28; female subjects, P = .83). However, among male ADHD cases, the mean age at PHV was significantly later among those treated with stimulants for ≥3 months by the time of their PHV compared with stimulant-naive cases (mean [SD], 13.5 years [1.0] vs. 12.9 years [1.2]; P = .002). Furthermore, among the male ADHD cases, there was a positive correlation between duration of stimulant usage before PHV and the age at PHV (r = 0.21, P = .01). Despite the later mean age at PHV for male ADHD cases treated ≥3 months, there was no difference in magnitude of PHV for stimulant-naive and stimulant-treated ADHD cases for male or female subjects.

    Effect of Stimulant Treatment on Height Z Scores

    We included all ADHD cases treated with stimulants for ≥3 months (N = 219 of the original 340) in this analysis. Stimulant treatment details for these 219 (data not shown) are very similar to those presented in Table 2. Fig 4 depicts the relationship between the change in the gender-specific height-for-age Z score from the beginning to the end of stimulant treatment and the cumulative duration of stimulant treatment among the cases with height measurements at both time points (n = 111, r = −0.08, P = .42). Among the 20 cases with a cumulative stimulant duration of <1 year, there was a slight decrease in Z scores between the 2 time points (mean = 0.19 and 0.12 at the beginning and end, respectively; P = .26). However, among the 59 cases with a cumulative stimulant duration of ≥3 years, the mean Z score decreased from 0.48 at the beginning of treatment to 0.33 at the end of treatment (P = .06).

    Adult Height

    Among the initial cohort of 340 ADHD cases and 680 age- and gender-matched non-ADHD controls, 742 subjects (285 cases, 457 controls) had ≥1 recorded adult height measurement available. Of these 742 subjects, 503 were included in the cohort of 637 patients summarized in Table 1. There was no difference in adult height between ADHD cases and controls for male subjects (mean difference = −0.4 cm, P = .56) or female subjects (mean difference = −1.1 cm, P = .29), or between stimulant-treated and stimulant-naive ADHD male subjects (mean difference = 0.6 cm, P = .64) or female subjects (mean difference = 0.2 cm, P = .93) (Table 4). Furthermore, there was no correlation between cumulative duration of stimulant treatment and adult height (male subjects: r = −0.02, P = .83; female subjects: r = 0.03, P = .84).

    Discussion

    In this longitudinal, population-based study, neither ADHD nor treatment with stimulants was associated with differences in magnitude of PHV during adolescence. However, among boys treated with stimulants, the age of PHV was slightly later (12.9 years for stimulant-naive, 13.6 years for ADHD cases treated ≥3 years). There was no significant correlation between duration of treatment and change in height-for-age Z scores at the beginning, the end, or 24 months after the end of stimulant treatment. However, among the cases with a cumulative stimulant duration of ≥3 years, the mean change in Z scores over the course of treatment approached statistical significance (P = .06), although the magnitude of change was clinically insignificant (mean change, 0.15). Neither ADHD nor treatment with stimulants was associated with differences in final adult height.

    ADHD was not associated with age or magnitude of PHV or final adult height. Previous studies have been contradictory,9 with reports of both decreased14 and increased14,47 growth among adolescent ADHD cases. However, these studies followed subjects during childhood but not to adulthood. In a study of clinically referred subjects followed into their early 20s, there were no differences in growth between ADHD cases and controls,25 and our findings, using non-referred ADHD cases and controls from a population-based birth cohort, provide additional evidence that ADHD itself does not negatively affect growth.

    The similarity in final adult height between ADHD cases treated with stimulants and those not treated is reassuring. This finding could reflect catch-up growth occurring after stimulant treatment was discontinued, as suggested by the Multimodal Treatment Study of Children With ADHD.5 However, consistent with Biederman et al,25 we found no significant difference in the magnitude of PHV between stimulant-treated and stimulant-naive ADHD cases. We also examined height-for-age Z scores in relation to stimulant treatment because previous research suggests that a child’s age and timing of treatment may matter.32–34 Overall, we found no significant difference in height Z scores at the beginning and at the end of stimulant treatment. Although the decrease in Z scores from the beginning to end of treatment among the ADHD cases treated for ≥3 years approached statistical significance (P = .06), the difference was clinically insignificant. For example, in an 18-year-old man with height ranging from 5 feet 9 inches to 6 feet 3 inches, a change in Z score of 0.16 equates to slightly <0.5 inches. There was a small, clinically insignificant increase in height Z scores between the end and 24 months after the end of stimulant treatment that does not suggest significant catch-up growth after stimulants were discontinued. There were no differences in adult height outcomes, either overall or based on duration of stimulant treatment, indicating that even for those treated for ≥3 years there was no overall impact on final adult height.

    Our findings should be interpreted with some potential limitations. These data are from a clinical setting. Clinicians were probably reviewing growth curves and may have made treatment decisions, such as cessation of stimulants or dietary recommendations, based on the child’s growth. Despite our findings, clinicians should continue to carefully monitor growth when making medication management decisions. The initial retrospective identification of ADHD cases may have been incomplete; however, our comprehensive access to all medical and school records for every birth cohort member makes it unlikely that we missed a significant number of cases.39 ADHD cases were not all treated with stimulant medications throughout adolescence, potentially accounting for the lack of differences in adult height between treated and untreated cases. However, we found no significant adverse impact of treatment on magnitude of PHV, growth during treatment, or adult height. It was impossible to assess the precision of growth measurements obtained during clinical visits. The setting of this study may limit generalizability, given that the population is largely white and middle class.37

    Conclusions

    Childhood ADHD is not associated with dysregulated growth. Furthermore, in this population-based cohort, stimulant treatment of childhood ADHD is not associated with deficits in adult height nor with a significant adverse impact on growth throughout childhood and adolescence.
