Association Between Post-Traumatic Stress Disorder (PTSD) and Lifetime DSM-5 Psychiatric Disorders among Veterans

"Overall, the prevalence of 6.3% for lifetime DSM-5 PTSD in U.S. veterans is lower than that reported in previous studies of era-specific (18.7% and 52%) (Dohrenwend et al., 2007; Ikin et al., 2010; Jakupcak et al., 2010) veteran cohorts but similar to a national sample of veterans (7.95%; Wisco et al., 2014) using previous diagnostic classifications. In part this may reflect the narrow definition used in the study. However, the lifetime prevalence of PTSD among veterans in this study was very similar to the prevalences of 6.4% and 7.8% reported for DSM-IV PTSD in the general U.S.

Prevalence of DMS-5 Post-Traumatic Stress Disorder in the United States

"Past-year (4.7%) and lifetime (6.1%) prevalences of DSM-5 PTSD represent 10,972,986 and 14,411,005 affected U.S. adults, respectively. Broadly consistent with previous findings [3, 4, 42, 43], prevalences were higher among women and respondents aged <65 years, previously married, and with <high school education and household income <$70,000. Rates were also higher among Native American, but lower among Asian and Pacific Islander and Hispanic, versus non-Hispanic white, respondents, and lower among urban than rural residents.

Alcohol Use Disorder, Comorbidity/Co-Occurring Disorders, and Treatment

"We generally found significant associations between 12-month and lifetime AUD and other substance use disorders, major depressive disorder, bipolar I disorder, specific phobia, and antisocial and borderline PDs when we controlled for sociodemographic characteristics and other disorders. Significant associations between persistent depressive disorder, posttraumatic stress disorder, panic disorder, and generalized anxiety disorder with lifetime AUD were also observed.

Demographics of Alcohol Use Disorder in the United States

"Consistent with previous research, rates of AUD [Alcohol Use Disorder] were greater among men than women.1,2,5,14 Age was inversely related to 12-month AUD, a finding also observed in earlier epidemiologic studies.1-5,14 Whether this result is owing to cohort effects, differential mortality, or recall bias merits further investigation. The 12-month rate of 7.1% for severe AUD among 18- to 29-year-old respondents is especially striking.

Drug Use Disorder and Comorbidity / Co-Occurring Conditions

"Drug use disorder was highly associated with alcohol and nicotine use disorders, with ORs (95% CIs) ranging from 2.5 (2.00–3.06) to 4.4 (3.80–5.19) across time frames and severity levels (Table 3). Twelve-month DUD was also positively associated with major depressive disorder, bipolar I, posttraumatic stress disorder, and antisocial PD (any and moderate to severe); dysthymia (any and mild); and borderline and schizotypal PDs across severity levels.

Estimated Prevalence of Drug Use Disorder in the United States

"In 2012–2013, the NESARC-III [National Epidemiologic Survey on Alcohol and Related Conditions–III], a large national survey of US adults, assessed 12-month and lifetime disorders, including DUDs, diagnosed according to the new DSM-5. The NESARC-III used rigorous survey and field methods and incorporated measures of functioning and detailed assessments of treatment use. The NESARC-III results indicate that the prevalence rates of 12-month and lifetime DSM-5 DUD were 3.9% and 9.9%, respectively, representing approximately 9,131,250 and 23,310,135 US adults, respectively.
