Key findings

Data from the National Health and Nutrition Examination Survey

• Approximately 6.0% of U.S. adolescents aged 12–19 reported psychotropic drug use in the past month.
• The use of antidepressants (3.2%) and attention deficit hyperactive disorder (ADHD) drugs (3.2%) was highest, followed by antipsychotics (1.0%); anxiolytics, sedatives, and hypnotics (0.5%); and antimanics (0.2%).
• Males (4.2%) were more likely than females (2.2%) to use ADHD drugs. Females (4.5%) were more likely than males (2.0%) to use antidepressants.
• Psychotropic drug use was higher among non-Hispanic white (8.2%) adolescents than non-Hispanic black (3.1%) and Mexican-American (2.9%) adolescents.
• About one-half of U.S. adolescents using psychotropic drugs in the past month had seen a mental health professional in the past year (53.3%).

Prior studies have shown an increase in psychotropic medication use among adolescents (1–6). However, most studies were based on clinical samples or high-risk populations. This report provides the estimate of any psychotropic medication use in the past month among U.S. noninstitutionalized adolescents aged 12–19 during 2005–2010, using National Health and Nutrition Examination Survey (NHANES) data. Psychotropic medication is a type of drug used to treat clinical psychiatric symptoms or mental disorders (7). Specific psychotropic drug types addressed are antidepressants; medications for attention deficit hyperactive disorder (ADHD); anxiolytics, sedatives, and hypnotics (ASH); antimanics; and antipsychotics. Adolescents using psychotropic drugs are further examined by sex, race and Hispanic origin, and mental health professional consultation.

• A total of 6.3% of the population aged 12–19 reported any psychotropic medication use in the past month. This included 4.5% taking only one psychotropic medication, and 1.8% taking two or more psychotropic medications (Figure 1).
• Antidepressants and ADHD medications (3.2% each) were the most frequent psychotropic drugs used among adolescents.
• One percent of adolescents reported the use of antipsychotic medications.
• Less than 1.0% of the U.S. adolescent population reported the use of prescribed ASH or antimanics.

Male and female adolescents differed in their use of psychotropic medications.

• Overall, females (6.7%) were more likely than males (5.9%) to report the use of any psychotropic medications in the past month (Figure 2).
• Females (4.5%) were more likely than males (2.0%) to report the use of antidepressants in the past month.
• In contrast, males (4.2%) were more likely than females (2.2%) to report using ADHD medications in the past month.

Non-Hispanic white adolescents were more likely to report the use of psychotropic medications.

• More than 8.0% of non-Hispanic white adolescents reported using psychotropic medications, compared with 3.1% of non-Hispanic black and 2.9% of Mexican-American adolescents (Figure 3).
• Non-Hispanic white adolescents (4.9%) were more likely than non-Hispanic black (0.5%) and Mexican-American (0.7%) adolescents to report antidepressant medication use.
• Non-Hispanic white adolescents (4.0%) were more likely than non-Hispanic black (2.2%) and Mexican-American (1.8%) adolescents to report the use of medications for ADHD.
• No significant difference was observed between non-Hispanic black and Mexican-American adolescents in the use of any psychotropic medications, antidepressants, or ADHD drugs.

About one-half of adolescents reporting any psychotropic medication use had seen a mental health professional in the past year.

• Approximately 43.0% of adolescents taking one psychotropic medication had seen a mental health professional in the past year (42.8%) (Figure 4).
• Almost 80.0% of adolescents taking two or more psychotropic medications had seen a mental health professional in the past year (79.5%).

Summary

During 2005–2010, 6.3% of the U.S. adolescent population aged 12–19 reported any psychotropic medication use in the past month. The percentages of psychotropic medication use by drug class were 3.2% for antidepressants, 3.2% for ADHD drugs, 1.0% for antipsychotics, 0.5% for ASH, and 0.2% for antimanics. Males were more likely than females to report ADHD medication use, while females were more likely than males to report antidepressant use. Non-Hispanic white adolescents reported higher antidepressant use than either non-Hispanic black or Mexican-American adolescents. A similar pattern was observed for ADHD medication use. Approximately one-half of the adolescent population reporting any psychotropic medication use in the past month had seen a mental health professional in the past year.

Depression and ADHD are the most common mental health disorders among adolescents. About 4.3% of adolescents aged 12–17 experienced depression in any 2-week period during 2005–2006 (8). Approximately 9.0% of children aged 5–17 had ever been diagnosed with ADHD during 2007–2009 (9). Treatment options other than prescription medication are available for depression, ADHD, and other mental health disorders, including psychosocial treatment and dietary management (10,11), both of which were unavailable for analysis in this report.

Definitions

Prescribed medication use: During an in-person home interview, NHANES participants are asked: “In the past 30 days, have you used or taken medication for which a prescription is needed?” Respondents who reply “Yes” are further asked to present to the interviewer the container of all prescribed medications mentioned. For each drug reported, the interviewer records the product’s complete name from the container. To standardize the medication nomenclature, all reported medication names are converted to standard generic names.

Psychotropic medication: Prescription drugs are classified according to Cerner Multum’s Lexicon (12) three-level nested therapeutic classification scheme. Antidepressants, antipsychotics, and ASH are identified using the second level of drug category codes 249, 251, and 67, respectively. Antimanics include lithium, carbamazepine, and valproic acid. Prescription drugs for ADHD (7,10) include amphetamine, atomoxetine, dexmethylphenidate, dextroamphetamine, guanfacine, lisdexamphetamine, methamphetamine, and methylphenidate. Respondents who reported using any of these five drug classes were classified as a psychotropic medication user. Adolescents who reported using more than one psychotropic drug were defined as multiple psychotropic medication users.

Contact with a mental health professional: Contact was based on the following survey question: “During the past 12 months, have you seen or talked to a mental health professional such as a psychologist, psychiatrist, psychiatric nurse, or clinical social worker about your health?”

Data source and methods

NHANES is a continuous, multipurpose cross-sectional survey of the civilian noninstitutionalized U.S. population designed to assess the overall health and nutrition of the American population in the contiguous states.

The sample design includes oversampling to obtain reliable estimates of health and nutritional measures for population subgroups. During 2005–2006, adolescent, elderly, low-income, black, and Mexican-American persons were oversampled. During 2007–2010, adolescents were no longer oversampled. In addition, Hispanic persons, rather than Mexican-American persons, were oversampled.

This study examines the percentage of prescription psychotropic medication use among adolescents aged 12–19. For the sample age group 12–15, a proxy respondent, usually one of the child’s parents, answered the questions in the household interview. Percentage estimates of psychotropic medication use based on NHANES data come from a nationally representative household sample. As such, they are likely conservative estimates, because they exclude higher-risk populations such as the homeless and those in correctional facilities and inpatient treatment facilities.

NHANES consists of an interview conducted in the participant’s home and a standardized physical examination performed in a mobile examination center. This report is based on interview data conducted at the respondent’s home. Therefore, interview sample weights, which account for the differential probabilities of selection, nonresponse, and noncoverage, are used for the analysis presented here.

Robust standard errors of the percentages are estimated using Taylor series linearization, a method that takes into consideration the sample weights and sample design. All statistical tests are two-sided using p < 0.05 as the level of significance. All reported comparisons are statistically significant unless otherwise indicated. Statistical analyses were conducted using SAS version 9.3 (SAS Institute, Cary, N.C.) and SUDAAN version 10.0 (RTI International, Research Triangle Park, N.C.).
