3 Editoril The Mentl Helth of Our Deploying Genertion Richrd F. Stoltz, PhD (CAPT, USN) there s fmous sying tht the only victor in wr is medicine. History hs provided us with mple lessons lerned from previous wrs, just s militry medicine is benefiting from knowledge gined from the lst 12 yers of persistent wrfre. These lessons hve led to n unprecedented understnding of how best to respond, implement nd deliver mentl helth services on nd off the bttlefield. More thn 2.6 million service members of the ctive component, Ntionl Gurd nd Reserve hve deployed mny repetedly in support of combt opertions in Irq nd Afghnistn over the lst 12 yers. It is well recognized tht exposure to combt cn increse the risk of developing mentl helth conditions. Although the mjority of service members who hve deployed will not develop depression, nxiety, or post-trumtic stress disorder (PTSD), everyone who hs deployed will chnge to some degree nd, once home, will find new norml in firly quick mount of time. For some service members, though, it doesn t work tht wy. Some combt veterns hve witnessed gruesome events. They might hve seen their best efforts fil to prevent their friends from being killed or wounded by improvised explosive device (IED) explosions or other hostile fire. They hve hd to come to terms with the fct tht ny person, including women nd children, could be their enemy. Even more disturbing, they my hve been involved in the ccidentl deths of innocent civilins including children. Sometimes the relity of wht these service members hve experienced is indescribble nd usully unimginble to those who hve not been to wr nd witnessed its horrors. When mny service members return from deployments, they re confused nd ferful nd they experience high levels of depression, nxiety, or symptoms of PTSD they do not fully understnd. Mny troubled service members despertely wnt to sleep better t night but cn t. They long to feel more inner pece nd to not repetedly revisit memories of pst horrific experiences. They yern to be better spouses, better prents, nd better friends, but ren t sure how to mke tht hppen. They my experience n increse in lcohol buse but hve trouble cutting bck. All of this might be excerbted by physicl injuries nd vrious trums from previous deployments. Some service members my try to convince themselves tht their problems re not serious in order to justify their decision to void seeking professionl help. They serch for wys to block n wreness of their inner mlise. This my work temporrily, but ny relief is usully short lived, thwrting their bility to hel. Others my wnt professionl help but fer it will hrm their creers or they will be perceived s wek by those closest to them. Mny who tke the courgeous step to receive tretment re plesed with the results. Whether tht ssistnce involves socil support, eduction, group therpy, mindbody medicine, virtul relity, hypnosis, spiritul counseling, cognitive behviorl therpy, mindfulness, medittion, or other interventions, it is impertive to recognize tht the best tretment for some my not be the best tretment for others nd sometimes it tkes while to figure this out. It s eqully importnt to understnd tht wht service members minds needed to do to increse their chnces of survivl in combt is the opposite of wht their minds will need to do to hel. In the combt setting blocking out inner turmoil nd remining fully lert to one s dngerous environment is criticl. In sfe settings it is importnt to find wys to work through troubling thoughts nd feelings tht wr Pge 2 MSMR Vol. 20 No. 7 July 2013

In combintion with therpy it s often helpful for service members to shre their combt experiences with other veterns who ve hd similr experiences. Exercise, good nutrition nd helthy sleep re lso beneficil. There is still much to lern bout how best to help service members who re experiencing highly tretble conditions such s PTSD, depression, nxiety nd substnce buse.

5 Summry of Mentl Disorder Hospitliztions, Active nd Reserve Components, U.S. Armed Forces, Mentl disorders re the leding cuse of hospitl bed dys nd the second leding cuse of medicl encounters for ctive component service members in the U.S. militry. Mentl disorder-relted hospitliztions mong militry members hve incresed in both number nd durtion since 2006; mentl disorders re the only illness/injury ctegory for which hospitliztion rtes hve mrkedly incresed during the first 11 yers of the Irq nd Afghnistn wrs. Between 2000 nd 2012, 159,107 ctive component service members experienced 192,317 mentl disorder hospitliztions. There were pproximtely 87 percent more mentl disorder-relted hospitliztions in 2011 (n=21,646) thn in 2000 (n=11,604); in 2012, this number declined slightly (n=21,360). The overll increse since 2006 ws lrgely due to shrp increses in hospitliztions for post-trumtic stress disorder (PTSD), depression, lcohol buse nd dependence, nd djustment disorder (% increses in hospitliztions, : PTSD: 192%; depression: 66%; lcohol buse nd dependence: 110%; djustment disorder: 52%). Similr rtes of increse occurred mong members of the reserve component. The percentge of mentl disorder hospitliztion records with second (concurrent) mentl disorder dignosis incresed during the surveillnce period; more thn hlf of ll service members hospitlized for mentl disorder hd second mentl disorder dignosis documented during the sme hospitliztion. mentl disorders ccount for more hospitliztions of U.S. service members thn ny other mjor dignostic ctegory. 1,2 Mentl disorder-relted hospitliztions mong militry members hve incresed in both number nd durtion since 2006; 3 in ddition, mentl disorders re the only illness/ injury ctegory for which hospitliztion rtes hve incresed during the Irq nd Afghnistn wrs. 4 The public helth impct nd occuptionl burden ssocited with mentl disorder-relted hospitliztions is considerble; for exmple, ttrition rtes for service members within six months of mentl disorder-relted hospitliztion re four times higher thn those for hospitliztion for other injuries or illness 5 nd the risk of dying from suicide is gretly elevted in ctive component service members who hve been hospitlized for mentl disorder..6 This report documents the number nd length of mentl disorder-relted hospitliztions in the ctive nd reserve components of the U.S. Armed Forces during the pst 13 yers. The frequencies of cooccurring mentl disorder dignoses re lso exmined. METHODS The surveillnce period ws 1 Jnury 2000 to 31 December The surveillnce popultion included ll individuls who served in the ctive nd reserve (Reserve nd Gurd) components of the U.S. Armed Services t ny time during the surveillnce period. Endpoints of nlyses were mentl disorder-relted hospitliztions; for nlysis purposes, these were defined by hospitliztion records with primry (firstlisted) dignoses of mentl disorder or dignosis of suicidl idetion. For summry purposes, mentl disorder-relted hospitliztions were grouped into twelve ctegories: djustment disorders, lcohol buse nd dependence, substnce buse nd dependence, nxiety, post-trumtic stress disorder (PTSD), depression, bipolr disorder, personlity disorders, schizophreni, other psychoses, other mentl helth disorders nd suicidl idetion (Tble 1). Hospitliztions with suicidl idetion s the primry dignosis re summrized only from 2006 forwrd s the dignostic code for suicidl idetion ws not dded to the Interntionl Clssifiction of Diseses (ICD-9-CM) until October An individul could be counted in more thn one mentl disorder ctegory. All unique hospitliztion records were summrized; n individul could be counted multiple times if tht individul hd multiple mentl disorder-relted hospitliztion records occurring on different dys. Some nlyses were performed only for the subset of the six most frequent mentl disorder hospitliztions (i.e., hospitliztions for djustment disorder, lcohol buse nd dependence, bipolr disorder, depression, PTSD, nd substnce buse nd dependence). For these six ctegories of mentl disorder-relted hospitliztion, the percentges of mentl disorder-relted hospitliztions with nother mentl disorder dignosis in dignostic positions two through eight in the sme hospitliztion record were clculted. RESULTS During the 13-yer surveillnce period, 159,107 ctive component service members experienced totl of 192,317 mentl disorder hospitliztions.

There were pproximtely 87 percent more mentl disorder-relted hospitliztions in 2011 (n=21,646) thn in 2000 (n=11,604); in 2012, this number declined slightly (n=21,360) (Figure 1). The overll increse since 2006 ws lrgely due to shrp increses in hospitliztions for PTSD, depression, lcohol buse nd dependence, nd djustment disorder (% increses in hospitliztions, : PTSD: 192%; depression: 66%; lcohol buse nd dependence: 110%; djustment disorder: 52%) (Figure 1). During the sme period, 22,456 reserve component service members experienced totl of 26,925 mentl disorder hospitliztions. The number of mentl disorder-relted hospitliztions lmost doubled from 2002 (n=961) to 2003 (n=1,868) nd then remined reltively stble though As in the ctive component, nnul numbers of mentl disorder-relted hospitliztions fter 2006 incresed ech yer through 2011; between 2006 (n=1,919) nd 2011 (n=3,101), mentl disorder-relted hospitliztions incresed by pproximtely 62 percent (Figure 2). In ctive component service members, during ech yer from 2000 to 2003, there were more hospitliztions for djustment disorders thn ny other ctegory of mentl disorders; however, during ech yer from 2004 to 2012, there were more hospitliztions for depression thn ny other ctegory of mentl disorders (Figure 1).

Hospitliztion rtes for depression continued to increse through 2012 nd remined higher thn rtes in ny other mentl disorder ctegory (Figure 3). Among reserve component service members, there were more hospitliztions for depression thn for djustment disorders in every yer of the surveillnce period (Figure 2). The men nd medin length of mentl disorder-relted hospitliztions vried substntilly by mentl disorder ctegory (dt not shown). Between 2000 nd 2012, hospitliztions for schizophreni hd the longest medin lengths of ny mentl disorder-relted hospitliztions, lthough the medin length for these hospitliztions declined over the course of the time period (medin length in 2000: 19 dys versus medin length in 2012: 10 dys). In contrst, both men nd medin lengths of hospitliztions for lcohol buse nd dependence nd PTSD incresed between 2009 nd The nnul men length of hospitliztions where lcohol buse nd dependence ws the primry dignosis incresed from 9 dys in 2009 to 12 dys in 2012; similr increses in medin length were lso observed (2009: 4 dys; 2012: 6 dys). The lrgest increse in length of hospitliztion ws observed for PTSD-relted hospitliztions; the length of PTSD-relted hospitliztions incresed from men of 10 dys nd medin length of 6 dys in 2000 to men length of 17 dys nd medin length of 9 dys in Men nd medin lengths of hospitliztion for other ctegories of mentl disorder-relted hospitliztions remined reltively stble over the 13-yer period (dt not shown).

Femles were more likely to be hospitlized for djustment disorders, PTSD, depression, nd bipolr disorder nd reltively less likely to be hospitlized for lcohol nd substnce buse or dependence thn mles. Both mles nd femles less thn 20 yers of ge hd the highest hospitliztion rtes for djustment disorder. Hospitliztion rtes for lcohol nd substnce buse nd dependence were highest in mles nd femles between the ges of 20 nd 29. Hospitliztion rtes for PTSD peked for mles in the ge group; for femles, rtes were highest in those yers of ge. For mles, hospitliztion rtes for depression nd bipolr disorder were highest in those yers of ge, while these hospitliztion rtes were highest in the youngest femles (Tble 3). Almost 80 percent of service members hospitlized for djustment disorder hd never deployed prior to their hospitliztions; on the other hnd, only 21.9 percent of those hospitlized with PTSD s the primry dignosis hd never deployed. Overll, those who hd deployed t lest once prior to their mentl disorder-relted hospitliztion hd lower hospitliztion rtes for djustment disorder, depression nd bipolr disorder nd higher hospitliztion rtes for lcohol nd substnce buse nd dependence nd PTSD compred to those who hd never deployed (Tble 3). During the 13-yer surveillnce period, ctive component members were hospitlized for totl of 1,262,172 dys (3,458 cumultive person-yers) for tretment of these six mentl disorders. The nnul number of hospitl bed dys for tretment of mentl disorders remined firly stble until 2006; from 2006 through 2012, the nnul bed dys incresed for every disorder except bipolr disorder (Figure 5). The nnul number of hospitl bed dys ssocited with primry dignosis of PTSD, depression nd lcohol buse nd dependence incresed the most drmticlly fter EDITORIAL COMMENT This report documents continued increses in the numbers of mentl disorder-relted hospitliztions mong U.S. militry members since 2006; the increses overll re lrgely due to shrp rises in hospitliztions in recent yers for PTSD, depression, lcohol buse nd dependence, nd djustment disorders. The increses in mentl disorderrelted hospitliztions documented in this report re cuse for concern for severl resons; mong these is the demonstrted ssocition between psychitric hospitliztion nd risk of suicide. The ssocition between suicidl idetion nd psychitric hospitliztion is well documented. In n nlysis of psychitric hospitliztions in U.S. Nvy enlisted personnel, Booth- Kewley nd Lrson demonstrted strong ssocition between suicidl idetion nd hospitliztion for djustment disorder. 7 Other studies in militry popultions hve demonstrted similr ssocitions between suicide idetion nd other mentl disorders. 8 This report demonstrted tht suicidl idetion is frequent co-occurring dignosis in mny mentl disorder-relted hospitliztions. While the medin durtion of ll cuse hospitliztions hs remined stble since 2003, medin durtions of hospitliztions vry significntly by dignostic ctegory. 2 This report documents continued increses in men nd medin hospitliztion lengths for certin mentl disorders, specificlly, hospitliztions for PTSD nd lcohol buse nd dependence. Mny service members with mentl disorder-relted hospitliztion hd dignosis for nother mentl disorder in the sme record; mong ctive component members, 77 percent of service members hospitlized for PTSD hd nother mentl disorder dignosis in the sme record. Approximtely 28 percent of the PTSD hospitliztions hd dditionl dignoses of lcohol or substnce buse nd dependence. The comorbidity of PTSD nd lcohol misuse hs been incresingly recognized not only in Irq nd Afghnistn veterns but in veterns of other conflicts The incresing durtions of mentl disorder-relted hospitliztions my be due, in prt, to the chllenges of providing cre to service members presenting with multiple nd complex mentl disorder dignoses. The findings of this report reflect incresed hospitliztion rtes of cliniclly significnt mentl disorders, such s PTSD, mong veterns of one or more combt deployments. However, it is lso noteworthy tht significnt proportion of mentl disorder-relted hospitliztions occurred in service members who hd never deployed. For exmple, lmost 8 out of 10 service members hospitlized for djustment disorder hd not deployed prior to their hospitliztion. This finding my be relted to the observtion tht hospitliztion rtes for some mentl disorders Pge 10 MSMR Vol. 20 No. 7 July 2013

12 re highest in the youngest (nd lest experienced) service members (i.e., <20 yers). The findings of this report should be interpreted in light of severl limittions. This report included hospitliztions in fixed militry tretment fcilities or those hospitliztions pid for by the Militry Helth System (MHS). It did not include hospitliztions tht occurred in the combt theter, bord ships, during field exercises; however, the rte clcultions did include the person-time for the individuls in these loctions. Therefore, hospitliztion rtes for mentl disorders re likely underestimted. Similrly, while this report summrized records of mentl disorder-relted hospitliztions in reserve members, only hospitliztions tht occurred in militry medicl fcility or were pid for by the MHS were cptured. Mny, if not most, reserve members hve lternte mens of receiving medicl cre (i.e., privte medicl insurnce); therefore, this report likely gretly underestimtes the number of mentl disorder-relted hospitliztions in members of the reserve component. 5.

14 Mentl Disorders nd Mentl Helth Problems Among Recruit Trinees, U.S. Armed Forces, Ptrick Monhn, MD, MPH (Col, USAF); Zheng Hu, MS; Ptrici Rohrbeck, DrPH, MPH, CPH (Mj, USAF) Annul counts nd rtes of incident dignoses of mentl disorders or mentl helth problems hve incresed in the U.S. militry ctive component since 2000, but less is known bout recruit trinees. From 2000 to 2012, 49,999 ctive component recruit trinees were dignosed with t lest one mentl disorder, nd 7,917 hd multiple mentl disorder dignoses. Annul incidence rtes of t lest one mentl disorder decresed by pproximtely 37.4 percent over the lst 13 yers. Approximtely 80.5 percent of ll incident mentl disorder dignoses were ttributble to djustment disorders, depression, nd other mentl disorders. Rtes of incident mentl disorder dignoses were higher in femles thn mles. Even though the Army hd the highest overll incidence rtes of mentl disorders, the Air Force hd slightly higher rtes for djustment disorder, nd the Nvy hd higher rtes of lcohol buserelted disorders, post-trumtic stress disorder (PTSD), nxiety, other psychoses, nd personlity disorders. These findings document differences in the mentl disorders experienced by recruit trinees compred to members of the ctive component of the U.S. militry overll. Continued focus on detection nd tretment of mentl helth issues during bsic trining is wrrnted. mentl disorders ccount for significnt morbidity, helth cre utiliztion, disbility, nd ttrition from militry service. 1 A recent descriptive epidemiologicl study of mentl disorders nd mentl helth problems in the ctive component between 2000 nd 2011 showed tht, for most ctegories of mentl disorders, rtes of incident dignoses were highest mong the youngest (nd thus most junior) service members. 2 Crude incidence rtes of djustment disorders, post trumtic stress disorder (PTSD), personlity disorders, other mentl disorders, schizophreni, nd other psychoses were higher mong the youngest (less thn 20 yers of ge) group of service members. 2 Also, significnt proportion of mentl helth problems relted to life circumstnces occurred in the first six months of service members militry service. 2 Psychitric disorders re mong the top ten cuses of conditions tht existed before service nd of disbility dischrges ech yer. 3 Existing prior to service (EPS) medicl conditions re defined s those verified to hve existed before the recruit begn militry service nd if the complictions leding to dischrge rose no more thn 180 dys fter the recruit trinee begn duty. 3 Approximtely five percent of ll new ctive duty enlistees (excluding U.S. Air Force recruit trinees) re dischrged within six months of enlistment due to complictions of medicl conditions tht existed prior to service. 4 Mentl disorder resons for EPS dischrge vry by service: psychitric cuses ccounted for the most EPS dischrges in the Army (29.1%) nd the Mrine Corps (43.9%) between 2007 nd 2011, while the percentge in the Air Force for tht period ws 0.4 percent. 5 The most common cuses of hospitliztions within the first yer of service from 2005 to 2010 were neurotic or personlity disorders (16.7%) nd other psychoses (5.9%). 5 Few studies hve evluted militry personnel longitudinlly fter dignosis of mentl disorder. Hoge et l. 6 demonstrted tht, mong militry cohort in the 1990s, 47 percent of those hospitlized for the first time with mentl disorder left militry service within six months; this proportion ws significntly higher thn tht for ny one of 15 other disese ctegories. While five to six percent of Air Force recruit trinees hve historiclly experienced emotionl difficulties tht result in referrl for psychologicl evlution, 7 one study in Air Force recruit trinees found tht only 58 percent of those referred for mentl helth evlution nd returned to duty ultimtely grduted from bsic militry trining; 8 the most common reson for dischrge ws EPS (26%) followed by continued mentl helth problems (21%). Another study in Air Force recruit trinees showed n nnul mentl disorder-relted seprtion rte of 4.2 percent; djustment disorders nd depressive disorders were the most frequent dignoses relted to recommendtion for seprtion. 9 This report summrizes counts, rtes, nd trends of incident mentl disorder-specific dignoses (ICD-9-CM: ) mong ctive component U.S. recruit trinees over 13-yer surveillnce period. It lso summrizes counts, rtes, nd trends of incident mentl helth problems (documented with mentl helth-relted V-codes) mong ctive component U.S. recruit trinees during the sme time period. METHODS The surveillnce period ws 1 Jnury 2000 to 31 December The surveillnce popultion included ll individuls who entered bsic trining in the U.S. Armed Forces t the grdes of E1 to E4 t ny time during the surveillnce period.

15 rnging from 6 to 10 weeks; recruit trinees who hd to repet ll or portion of their bsic trining period were excluded. No surveillnce ws conducted for recruit trinees during ny follow-on trining such s Advnced Individul Trining (AIT) or other jobs requiring technicl trining. Cost Gurd dt prior to 2007 ws incomplete nd thus excluded from the report. All dt used to determine incident mentl disorder-specific dignoses nd mentl helth problems were derived from records routinely mintined in the Defense Medicl Surveillnce System. These records document both mbultory encounters nd hospitliztions of ctive component members of the U.S. Armed Forces in fixed militry nd civilin (if reimbursed through the Militry Helth System) tretment fcilities. For surveillnce purposes, mentl disorders were scertined from records of medicl encounters tht included mentl disorder-specific dignoses (ICD-9-CM , the entire mentl disorders section of the ICD-9-CM coding guide) in the first or second dignostic position; dignoses of pervsive developmentl disorder (ICD-9-CM: 299.xx), specific delys in development (ICD-9-CM: 315.xx), nd mentl retrdtion (ICD-9-CM: 317.xx- 319.xx) were excluded from the nlysis. Dignoses of mentl helth problems were scertined from records of helth cre encounters tht included V-coded dignoses indictive of psychosocil or behviorl helth issues in the first or second dignostic position. For summry purposes, mentl disorder-specific dignoses indictive of djustment rection, substnce buse, nxiety disorder, PTSD, or depressive disorder were grouped into ctegories defined by Sel et l. 10 nd previously reported in the MSMR 11 with two modifictions s follows: depressive disorder, not elsewhere clssified (ICD- 9-CM: 311) ws included in the depression ctegory insted of the other mentl dignoses ctegory. Also, lcohol buse nd dependence dignoses nd substnce buse nd dependence dignoses were treted s two discrete ctegories. Dignoses indictive of personlity disorder or other psychotic disorders were grouped using the ctegories developed by the Agency for Helthcre Reserch nd Qulity (AHRQ). 12 A cse of schizophreni ws defined s n ctive component service member with t lest one hospitliztion or four outptient encounters tht were documented with schizophreni-specific dignoses (ICD-9-CM: 295). V-coded dignoses indictive of mentl helth problems were grouped into five ctegories using previously published criteri. 13 Ech incident dignosis of mentl disorder (ICD-9-CM: ) or mentl helth problem (selected V-codes) ws defined by hospitliztion with n indictor dignosis in the first or second dignostic position; two outptient visits within 180 dys documented with indictor dignoses (from the sme mentl disorder or mentl helth problem-specific ctegory) in the first or second dignostic positions; or single outptient visit in psychitric or mentl helth cre specilty setting (defined by Medicl Expense nd Performnce Reporting System [MEPRS] code: BF) with n indictor dignosis in the first or second dignostic position. As described previously, the cse definition for schizophreni required four outptient encounters. Service members who were dignosed with more thn one mentl disorder during the surveillnce period were considered incident cses in ech ctegory in which they fulfilled the cse-defining criteri. Service members could be incident cses only once in ech mentl disorder-specific ctegory. Only service members with no incident mentl disorder-specific dignoses (ICD-9-CM: ) during the surveillnce period were eligible for inclusion s cses of incident mentl helth problems (selected V-codes). RESULTS During the 13-yer surveillnce period, 49,999 or 2.4 percent of ll ctive component recruit trinees were dignosed with t lest one mentl disorder; of these individuls, 7,917 (15.8%) were dignosed with mentl disorders in more thn one dignostic ctegory (Tble 1). Overll, there were 59,419 incident dignoses of mentl disorders in ll dignostic ctegories.

The crude incidence rtes for djustment disorders fluctuted between 81.8 per 1,000 p-yrs (in 2000) to per 1,000 p-yrs (in 2008), but declined stedily fter 2009; nnul rtes were lower ech yer fter 2010 thn in ny of the previous 11 yers (Figure 1). Crude incidence rtes for other mentl disorders incresed shrply from 2005 to 2006, but then declined from 2006 through The crude incidence rtes for depression grdully incresed from 2003 through 2007, but continuously decresed fter In contrst, crude incidence rtes of dignoses of personlity disorders declined stedily during the surveillnce period, nd crude incidence rtes for nxiety, schizophreni, other psychoses, PTSD, nd lcohol nd substnce buse-relted disorders were reltively stble or declined during the period (Figure 1). In generl, rtes of incident mentl disorder dignoses remined stedy with incresing ge, except for nxiety disorders, depression, schizophreni, nd other psychoses, which hd higher rtes in individuls ge 25 nd bove compred to younger recruit trinees ( Figures 2). In contrst, crude incidence rtes of personlity disorders were lower in individuls ge 25 nd bove compred to younger trinees. Crude incidence rtes of djustment, nxiety, nd personlity disorders s well s depression were pproximtely twice s high mong femles s mles, nd crude incidence rtes of PTSD were 5.6 times higher mong femles (femles: 11.5 per 1,000 p-yrs; mles: 1.7 per 1,000 p-yrs) (Figure 3). Overll incidence rtes of mentl disorders were higher in the Army (169.2 per 1,000 p-yrs) nd lower in the Mrine Corps (92.6 per 1,000 p-yrs) thn in ny of the other Services.

The crude incidence rte of personlity disorders in the Nvy ws 5.8 times higher thn the Army nd 2.6 times higher thn the Mrine Corps (Figure 5). During the surveillnce period, there were 11,273 incident reports of mentl helth problems (documented with V-codes) or 0.5 percent mong ll ctive component recruit trinees who were not dignosed with mentl disorder (ICD-9-CM: ). During the period, nerly 98.9 percent of ll incident reports of mentl helth problems were relted to life circumstnces (e.g., filure to djust, mritl problems, finncil difficulties, berevement, cculturtion difficulties) (n=11,145) (Tble 2). Rtes of ny mentl helth problems (s reported with V-codes) were reltively stble during the period with smll pek in 2006, but decresing since 2007 nd then stbilized (Figure 6). Compred to rtes of ny mentl helth problem, ny mentl disorder dignosis rtes were consistently higher (139.1 per 1,000 p-yrs compred to 31.4 per 1,000 p-yrs) ( Tbles 1, 2, Figure 6). Of note, rtes of ny mentl disorder dignoses decresed from 2008 through 2010 nd hve been reltively stble since (Figure 6). Rtes of mentl helth problems relted to life circumstnces declined from 2000 to 2004 (28.6 per 1,000 p-yrs), incresed to shrp pek in 2006 (44.7 per 1,000 p-yrs), nd then declined shrply through 2008 (19.8 per 1,000 p-yrs). This ctegory remined stble since The crude incidence rte of life circumstnce-relted problems ws more thn 54 percent lower in the lst yer (2012: 19.9 per 1,000 p-yrs) compred to the first yer of the period (2000: 44.1 per 1,000 p-yrs) (dt not shown). Among mentl helth problems, the Cost Gurd hd the highest rte of life circumstnce-relted dignoses, which ws 20.6 times higher thn the Army, 17.0 times higher thn the Mrine Corps, nd 3.7 times higher thn the Air Force (Figure 7). EDITORIAL COMMENT This report provides comprehensive overview of incident dignoses of mentl disorders nd reports of mentl helth problems mong ctive component recruit trinees of the U.S. Armed Forces during the lst 13 yers. The report reitertes nd reemphsizes previously reported findings regrding mentl disorders/problems mong U.S. militry members. This report, however, illumintes differences between mentl disorders/mentl helth problems of recruit trinees compred to those of ctive component service members in generl. There re unique nd inherently stressful physicl nd mentl chllenges ssocited with the introduction of civilins to militry environments nd the commencement of bsic militry (recruit) trining. Even though mjority (over 90%) of recruit trinees go through their trining without mentl disorder incident, some present with mentl helth-relted TABLE 2.

As result, erly psychologicl evlutions nd incresed ccess to mentl helth services during the bsic trining period my help retin otherwise motivted nd qulified service men nd women. The ntures nd mgnitudes of mentl disorders nd relted problems in militry bsic trining should be interpreted with considertion tht the mjority of recruit trinees re 25 yers of ge or younger. In this regrd, the Centers for Disese Control nd Prevention (CDC) reported tht mentl disorders re chronic helth conditions tht my interfere with helthy development nd continue to cuse problems into dulthood. 14 Bsed on the Ntionl Reserch Council nd Institute of Medicine report, n estimted 13 to 20 percent of children in the U.S. experience mentl helth disorder in given yer. 14 This lrge nd growing problem of mentl disorders in the dolescent U.S. popultion will ffect militry service when young nd otherwise helthy dults re recruited nd present for bsic trining; mentl disorder-relted problems my re-surfce during the bsic trining period. In the U.S. dolescent popultion, the most common mentl disorders re ttention deficit hyperctivity disorder (ADHD), disruptive behviorl disorders such s oppositionl defint disorder nd conduct disorder, utism spectrum disorders, mood nd nxiety disorders including depression, substnce use disorders, nd Tourette syndrome. 14 In this study cohort, djustment disorders, depression, other mentl disorders, nxiety, nd personlity disorders were the most common dignoses. These findings suggest tht mentl disorders nd mentl helth problems in ctive component recruit trinees prtilly reflect the ptterns observed in the dolescent U.S. popultion. The findings of this report re consistent with previously identified ge-relted risks in the ctive component U.S. Armed Forces. For most ctegories of mentl disorders nd mentl helth problems, rtes of incident dignoses were highest mong the youngest (nd thus likely most junior) service members. Since recruit trinees re the youngest nd most junior of ll militry members nd new to the militry environment, they my not perceive stigms nd/ or fers of negtive impcts on their militry creers when seeking mentl helth cre. As result, nd in comprison to ctive component (older nd higher rnking) service members, recruit trinees my be more likely to seek mentl helth cre thn those who re older. Other findings of this report re different from previous reports identifying mentl disorder-relted risks in the ctive component U.S. Armed Forces. Of note, rtes of mentl disorders nd mentl helth problems mong recruit trinees hve either declined or remined stble over the pst 13 yers, wheres the mjority of the sme mentl disorder outcomes hve incresed mong ctive component service members. 2 In both popultions, djustment disorders hd the highest incidence rte compred to other mentl disorders, yet when compred to the ctive component popultion, the rte ws twice s high in recruit trinees. The higher rte in trinees my be the result of individuls experiencing stressful, fstpced, nd intense environment such s bsic trining for the first time in their lives. In both popultions, femles experience higher incidence rtes of mentl disorders compred to mles. Although this reltionship pplies to ll mentl disorder ctegories in recruit trinees, ctive component mles hve higher incidence rtes thn femles for lcohol nd substnce buse-relted disorders nd PTSD. 2 Alcohol nd substnce use is prohibited in bsic trining, nd since it is strictly monitored environment, the incidence rtes re mong the lowest compred to other mentl disorders. As result, lcohol nd substnce buse problems re not common in the bsic trining popultion. Similrly, PTSD is often ssocited with deployments nd is therefore more likely to occur mong ctive component service members thn recruit trinees. When compring the impct of service ffilition on mentl disorder incidence, service members in the Army hd consistently higher rtes thn ny of the other Services over the pst 12 yers; ll Services showed incresing trends. 2 Among recruit trinees, service ffilition does not present clerly observble trend, which my be due to the vrition in nd chnges to trining content nd length over the pst 13 yers. Incidence rtes for mentl disorders by Service in recruit trinees hve fluctuted, nd in recent yers Army, Mrine Corps, nd Cost Gurd show decresing trends, while Nvy nd Air Force rtes show incresing trends. There re significnt limittions to this report tht should be considered when interpreting the results. For exmple, incident cses of mentl disorders nd mentl helth problems were scertined from ICD-9-CM coded dignoses tht were reported on stndrdized dministrtive records of outptient clinic visits nd hospitliztions. Such records re not completely relible indictors of the numbers nd types of mentl disorders nd mentl helth problems tht ctully ffect militry members. For exmple, the numbers reported here re underestimtes to the extent tht ffected service members did not seek cre or received cre tht is not routinely documented in records tht were used for this nlysis; tht mentl disorders nd July 2013 Vol. 20 No. 7 MSMR Pge 17

19 mentl helth problems were not dignosed or reported on stndrdized records of cre; nd/or tht some indictor dignoses were miscoded or incorrectly trnscribed on the centrlly trnsmitted records. On the other hnd, some conditions my hve been erroneously dignosed or miscoded s mentl disorders or mentl helth problems (e.g., screening visits). Additionlly, no prior medicl history ws vilble, so ech initil mentl disorder encounter ws considered n incident dignosis even though some mentl disorder-relted conditions my hve existed prior to service. Finlly, s with most helth surveillnce-relted nlyses mong U.S. militry members, this report relies on dt in the Defense Medicl Surveillnce System (DMSS). The DMSS integrtes records of nerly ll medicl encounters of ctive component members in fixed (i.e., not deployed or t se) militry medicl fcilities. Administrtive medicl record systems, like DMSS, enble comprehensive surveillnce of medicl conditions of interest through identifiction of likely cses; such cses re identified by using surveillnce cse definitions tht re bsed entirely or in prt on indictor ICD-9-CM codes. Other considertions in the construction of surveillnce cse definitions include the clinicl setting in which dignoses of interest re mde (e.g., hospitliztion, relevnt specilty clinic), frequency nd timing of indictor dignoses, nd the priority with which dignoses of interest re reported (e.g., first listed versus others).

On verge, 517 recruit trinees were hospitlized yerly due to mentl disorder. The highest number nd rte of mentl disorder-relted hospitliztions were in 2000 (n=793; per 10,000 personyers [p-yrs]) nd the lowest number nd rte were in 2011 (n=275; per 10,000 p-yrs). From 2008 to 2012 there ws 45.5 percent decrese in the rte of mentl disorder-relted hospitliztions. Adjustment disorder ws the most commonly recorded mentl disorder dignosis ssocited with hospitliztion mong recruit trinees (verge: 282 per yer), while depressive disorder ws the second most common dignosis (verge: 79 per yer).
