BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) is a common diagnosis in childhood, characterized by persistent impairing inattention, hyperactivity, and impulsivity with symptoms recognized in patients before age 12.1 Since ADHD is the most common pediatric neurodevelopmental disorder diagnosed in the U.S., this condition has readiness and force health importance to the Department of Defense (DoD), and its high prevalence in the adolescent and adult civilian population affects the pool of military applicants.2 Current DoD accession policy lists ADHD as disqualifying for military applicants if they meet any of the following conditions: ADHD medication prescribed in the previous 24 months, an educational plan or work accommodation after age 14, a history of comorbid mental health disorders, or documentation of adverse academic, occupational, or work performance.3

The prevalence of ADHD in U.S. children aged 2–17 is estimated to range from 9–11% with approximately two-thirds of children with ADHD having at least 1 other mental, emotional, or behavioral disorder.4 In 2016, U.S. surveillance data revealed that 62% of children diagnosed with ADHD currently take medication for the condition.5 Although symptoms can resolve after childhood, the most recent estimate of overall prevalence of adult ADHD in the U.S. is 4.4%.4 Unpublished data from an analysis conducted using Defense Medical Surveillance System (DMSS) data, demonstrated annual ADHD prevalence estimates ranging from 1.7–3.7% in the active component from 2000–2016 with a peak prevalence in 2011 (E. T. Reeves, MD, unpublished data, 2017). Although patients with ADHD are more likely to have comorbid mood, anxiety, and substance use disorders,4,6–8 patients receiving ADHD medications may be protected from the development of these associated mental health conditions.9,10

The last major change to DoD accession policy standards for ADHD occurred in 2010 and resulted in more restrictive requirements (no medications for more than 24 months cumulative after age 14 instead of the previous requirement of no medications within 12 months of enlistment). Although services can accept applicant waivers with less stringent restrictions (e.g., the Air Force will consider waivers for recruits stable off medications for 15 months), ADHD diagnosis is consistently a common disqualifier for military service. In 2017, ADHD and disruptive behavior disorders were the fifth most frequent medical disqualification of first-time enlisted active component military applicants.11 Although previous studies have evaluated the impact of ADHD on retention rates2 (also E. T. Reeves, MD, unpublished data, 2017) and its association with post-traumatic stress disorder (PTSD),6,8 no surveillance data have been published on recent estimates of the prevalence of ADHD diagnoses in active component military personnel or on what proportion of active component service members with ADHD are dispensed ADHD medications. The primary objectives of this study were to determine the prevalence of ADHD diagnoses among active component service members from 2014 through 2018 and the proportion of these service members who were prescribed medications to treat the condition.

METHODS

This descriptive study utilized a surveillance period from 1 January 2014 through 31 December 2018. The surveillance population included any member of the Army, Navy, Air Force, or Marine Corps who served in the active component at any point during the surveillance period. All data used to identify prevalent cases of ADHD were derived from records routinely stored in the DMSS, which is maintained by the Armed Forces Health Surveillance Division (AFHSD). DMSS includes medical encounter data (e.g., outpatient visits, hospitalizations) of active component members of the U.S. Armed Forces in military and civilian (if reimbursed through the Military Health System) treatment facilities. The DMSS also includes medical screening data from Military Entrance Processing Stations (MEPS) and records of prescribed and dispensed medications from the Pharmacy Data Transaction Service (PDTS) which were also included in this analysis. 

For surveillance purposes, an ADHD case was defined as a qualifying ADHD diagnosis in the first or second diagnostic position for diagnoses assigned during MEPS medical screening; or 1 hospitalization with any of the qualifying diagnoses of ADHD in the first or second diagnostic position; or 2 outpatient medical encounters within 180 days of each other, with any of the defining diagnoses of ADHD in the first or second diagnostic position; or 1 outpatient/TMDS medical encounter in a psychiatric or mental health specialty care setting, identified by a Medical Expense and Performance Reporting System (MEPRS) code beginning with ‘BF’, with a qualifying diagnosis of ADHD in the first or second diagnostic position. The International Classification of Diseases, 9th Revision (ICD-9) and International Classification of Diseases, 10th Revision (ICD-10) codes used to identify ADHD cases included all those falling under the parent codes 314 and F90, respectively. 

Individuals with a diagnosis of ADHD at any time during the surveillance period were assumed to be prevalent cases at the time of accession regardless of when they were formally diagnosed, since the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) requires the presence of symptoms prior to age 12 to meet the diagnostic criteria for ADHD.1 
To qualify as treated for ADHD, service members had to have a PDTS record documenting that they had been dispensed an FDA-licensed drug for the treatment of ADHD at least twice within 6 months (181 days) which is consistent with previous research.10 Active component service members dispensed ADHD medication with longer gaps than this threshold were classified as untreated. Medications used for the treatment of ADHD included stimulants (amphetamines, methylphenidates), guanfacine (Intuniv), clonidine (Kapvay), and atomoxetine (Strattera). Table 1 presents a comprehensive list of ADHD medications used in the current analysis. 

Crude annual prevalences of ADHD in the active component of the military during 2014–2018 were calculated and reported as percentages. In these calculations, the numerator was the number of prevalent cases of ADHD in active component service members and the denominator included all active component service members in service as of 30 June in the specified year. The proportion of active component service members diagnosed with ADHD who had been dispensed ADHD medication as defined above was calculated. Service members for whom ADHD medication was dispensed (treated) and those for whom ADHD medication was not dispensed (untreated) were compared on several background variables (i.e., sex, age group, race/ethnicity group, education level, marital status, branch of service, rank/grade, and military occupation) using chi-square tests. All analyses were conducted using SAS/STAT software, version 9.4 (2014, SAS Institute, Cary, NC). 

RESULTS

During the 5-year surveillance period, the crude annual ADHD prevalence among the active component declined from 3.9% in 2014 (n=58,691) to 2.8% in 2018 (n=41,338) (Figure 1). Compared to their respective counterparts, service members with less than a high school education, those who were divorced or widowed, non-Hispanic whites, Army members, senior enlisted members, and those in healthcare occupations had higher overall prevalence rates of ADHD. Females and males had similar annual and overall prevalence estimates (Figure 2, Table 2). Junior enlisted (E1–E4) service members trended down from the group with the second highest prevalence in 2014 to the group with the lowest prevalence in 2018 (Table 2, Figure 3).

The proportion of prevalent ADHD cases who were prescribed ADHD medication during the surveillance period was 60.2%. During the surveillance period, the majority of medications prescribed were stimulants alone (78.9–79.6%) compared to combined stimulant and non-stimulant (16.5–17.4%) or non-stimulant only (3.6%–3.9%) regimens (Figure 4). ADHD patients were more likely to be dispensed medication if they were older than 25 years of age, above junior enlisted rank (E1–E4), divorced/widowed, or in a healthcare occupation (Table 3).

EDITORIAL COMMENT

This report documents the prevalence and medication trends of ADHD among the active component service members during 2014–2018. Previous unpublished data on crude annual ADHD prevalence in the active component prior to 2014 revealed that a peak prevalence occurred in 2011 (E. T. Reeves, MD, unpublished data, 2017). The current study demonstrated a continued decline in the crude annual prevalence of ADHD in the military since the ADHD accession medical standard became more restrictive in 2010, particularly among junior enlisted (E1–E4) service members whose crude annual ADHD prevalence was lower than all other rank groups in 2018. In contrast, national adult ADHD prevalence rose during this same timeframe.12 The current study demonstrated a continued decline in the crude annual prevalence of ADHD in the military since the ADHD accession medical standard became more restrictive in 2010, particularly among junior enlisted (E1–E4) service members whose crude annual ADHD prevalence was  lower than all other rank groups in 2018. In contrast, national adult ADHD prevalence rose during this same timeframe.12

The ADHD population in the DoD differs from that in the U.S. civilian population on several key demographic characteristics. Female and male service members have similar prevalences whereas adult males are approximately twice as likely to be diagnosed with ADHD compared to females in the U.S. civilian population.4,5,13 Possible explanations for this finding include that the true ADHD prevalence in males and females may be more similar than previous research has suggested when performing comparable occupations or indicates that males with ADHD may have characteristics (such as more recent medication use) selecting them to be disqualified from the military enlistment process at higher rates than females. Additionally, annual ADHD prevalences among service members in healthcare occupations were consistently more than 2 times the prevalences of those in other occupations. The reasons for this difference are unknown but may reflect better access to care, more knowledge about ADHD and treatment options, greater acceptance by coworkers, and/or less physical exertion-based/more sedentary jobs compared to other military occupations.

Medication dispensed for ADHD in the military (60%) represents a proportion similar to that in the U.S. civilian population (62%).4,14 These data and the distribution of medication for ADHD patients should be informative for commanders and providers. For example, stimulant medication, as a controlled substance, can only be prescribed for 3 months at a time, which complicates the deployment readiness of service members with ADHD. 

Several limitations should be considered when interpreting the results of this study. The current study used data on medications dispensed to active component service members through PDTS, but the medication adherence of these patients could not be assessed. Furthermore, patients with ADHD in this study could have been prescribed the medications for other medical conditions (FDA approved indications or off-label use) or have obtained medications by other means without a prescription. Observational studies are subject to bias. For example, the (e.g., more severe symptoms or comorbid diseases) from the population of ADHD patients without medication. Diagnostic data were derived from coded medical encounters, including medical examination at MEPS, according to standardized health surveillance case definitions; however, this method may underestimate the prevalence of ADHD, especially in service members not actively being treated with medication for ADHD or who were deliberately withholding information related to prior ADHD diagnosis at MEPS assessment (i.e., misclassification bias). The earliest year of data collection was 2014 because of the inability to link to pharmacy data prior to that year. 

In conclusion, this study found a decreasing trend in crude annual ADHD prevalence in the active component from 2014–2018. In terms of military readiness, a decrease in prevalence lessens the demand on commanders and medical practitioners to make decisions about whether or not ADHD is a waiverable condition for deployments; however, this must be balanced with the effects that a strict ADHD accession policy has on limiting the pool of military applicants. Continued research and discussions should focus on the optimal ADHD accession military standard. Future studies should evaluate the impact of deployment on ADHD patients, the high prevalence of ADHD in healthcare occupations, and differences among service members with ADHD accessed to the military through various methods (i.e., MEPS, waivers, withholding the diagnosis, new ADHD diagnosis).

Insomnia and motor vehicle accident-related injuries, Active Component, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
Insomnia is the most common sleep disorder in adults and its incidence in the U.S. Armed Forces is increasing. A potential consequence of inadequate sleep is increased risk of motor vehicle accidents (MVAs). MVAs are the leading cause of peacetime deaths and a major cause of non-fatal injuries in the U.S. military members. To examine the relationship between insomnia and motor vehicle accident-related injuries (MVAs) in the U.S. military, this retrospective cohort study compared 2007 – 2016 incidence rates of MVA-related injuries between service members with diagnosed insomnia and service members without a diagnosis of insomnia. After adjustment for multiple covariates, during 2007 – 2016, active component service members with insomnia had more than double the rate of MVA-related injuries, compared to service members without insomnia. Findings:  •	Line graph shows the annual rates of motor vehicle accident-related injuries, active component service members with and without diagnoses of insomnia, U.S. Armed Forces, 2007 – 2016  •	Annual rates of MVA-related injuries were highest in the insomnia cohort in 2007 and 2008, and lowest in 2016 •	There were 5,587 cases of MVA-related injuries in the two cohorts during the surveillance period. •	Pie chart displays the following data: 1,738 (31.1%) in the unexposed cohort and 3,849 (68.9%) in the insomnia cohort The highest overall crude rates of MVA-related injuries were seen in service members who were: •	Less than 25 years old •	Junior enlisted rank/grade •	Armor/transport occupation •	 •	With a history of mental health diagnosis •	With a history of alcohol-related disorders Access the full report in the December 2017 (Vol. 24, No. 12).

Seizures among Active Component service members, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
This retrospective study estimated the rates of seizures diagnosed among deployed and non-deployed service members to identify factors associated with seizures and determine if seizure rates differed in deployment settings. It also attempted to evaluate the associations between seizures, traumatic brain injury (TBI), and post-traumatic stress disorder (PTSD) by assessing correlations between the incidence rates of seizures and prior diagnoses of TBI and PTSD. Seizures have been defined as paroxysmal neurologic episodes caused by abnormal neuronal activity in the brain. Approximately one in 10 individuals will experience a seizure in their lifetime. Line graph 1: Annual crude incidence rates of seizures among non-deployed service members, active component, U.S. Armed Forces data •	A total of 16,257 seizure events of all types were identified among non-deployed service members during the 10-year surveillance period. •	The overall incidence rate was 12.9 seizures per 10,000 person-years (p-yrs.) •	There was a decrease in the rate of seizures diagnosed in the active component of the military during the 10-year period. Rates reached their lowest point in 2015 – 9.0 seizures per 10,000 p-yrs. •	Annual rates were markedly higher among service members with recent PTSD and TBI diagnoses, and among those with prior seizure diagnoses. Line graph 2: Annual crude incidence rates of seizures by traumatic brain injury (TBI) and recent post-traumatic stress disorder (PTSD) diagnosis among non-deployed active component service members, U.S. Armed Forces •	For service members who had received both TBI and PTSD diagnoses, seizure rates among the deployed and the non-deployed were two and three times the rates among those with only one of those diagnoses, respectively. •	Rates of seizures tended to be higher among service members who were: in the Army or Marine Corps, Female, African American, Younger than age 30, Veterans of no more than one previous deployment, and in the occupations of combat arms, armor, or healthcare Line graph 3: Annual crude incidence rates of seizures diagnosed among service members deployed to Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn, U.S. Armed Forces, 2008 – 2016  •	A total of 814 cases of seizures were identified during deployment to operations in Iraq and Afghanistan during the 9-year surveillance period (2008 – 2016). •	For deployed service members, the overall incidence rate was 9.1 seizures per 10,000 p-yrs. •	Having either a TBI or recent PTSD diagnosis alone was associated with a 3-to 4-fold increase in the rate of seizures. •	Only 19 cases of seizures were diagnosed among deployed individuals with a recent PTSD diagnosis during the 9-year surveillance period. •	Overall incidence rates among deployed service members were highest for those in the Army, females, those younger than age 25, junior enlisted, and in healthcare occupations.
