Objectives
To present current, nationally representative US findings on the past-year and lifetime prevalences, sociodemographic correlates, psychiatric comorbidity, associated disability, and ...treatment of DSM-5 posttraumatic stress disorder (PTSD).
Methods
Face-to-face interviews with 36,309 adults in the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. PTSD, alcohol and drug use disorders, and selected mood, anxiety, and personality disorders were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-5.
Results
Past-year and lifetime prevalences were 4.7 and 6.1 %, higher for female, white, Native American, younger, and previously married respondents, those with <high school education and lower incomes, and rural residents. PTSD was significantly associated with a broad range of substance use, mood, anxiety, and personality disorders, and past-month disability. Among respondents with lifetime PTSD, 59.4 % sought treatment; an average of 4.5 years elapsed from disorder onset to first treatment.
Conclusions
DSM-5 PTSD is prevalent, highly comorbid, disabling, and associated with delayed help seeking. Additional research is needed to elucidate relationships identified herein, estimate PTSD-related costs, investigate hypotheses regarding etiology, course, and treatment, and support decisions about resource allocation to service delivery and research. Initiatives are needed to destigmatize PTSD, educate the public about its treatment, and encourage affected individuals to seek help.
To present nationally representative findings on prevalence, sociodemographic correlates, disability, and comorbidity of borderline personality disorder (BPD) among men and women.
Face-to-face ...interviews were conducted with 34,653 adults participating in the 2004-2005 Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. Personality disorder diagnoses were made using the Wave 2 Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version.
Prevalence of lifetime BPD was 5.9% (99% CI = 5.4 to 6.4). There were no differences in the rates of BPD among men (5.6%, 99% CI = 5.0 to 6.2) and women (6.2%, 99% CI = 5.6 to 6.9). BPD was more prevalent among Native American men, younger and separated/divorced/widowed adults, and those with lower incomes and education and was less prevalent among Hispanic men and women and Asian women. BPD was associated with substantial mental and physical disability, especially among women. High co-occurrence rates of mood and anxiety disorders with BPD were similar. With additional comorbidity controlled for, associations with bipolar disorder and schizotypal and narcissistic personality disorders remained strong and significant (odds ratios > or = 4.3). Associations of BPD with other specific disorders were no longer significant or were considerably weakened.
BPD is much more prevalent in the general population than previously recognized, is equally prevalent among men and women, and is associated with considerable mental and physical disability, especially among women. Unique and common factors may differentially contribute to disorder-specific comorbidity with BPD, and some of these associations appear to be sex-specific. There is a need for future epidemiologic, clinical, and genetically informed studies to identify unique and common factors that underlie disorder-specific comorbidity with BPD. Important sex differences observed in rates of BPD and associations with BPD can inform more focused, hypothesis-driven investigations of these factors.
Substance use disorders (SUDs) are moderately to highly heritable and are in part cross-transmitted genetically, as observed in twin and family studies. We performed exome-focused genotyping to ...examine the cross-transmission of four SUDs: alcohol use disorder (AUD, n = 4487); nicotine use disorder (NUD, n = 4394); cannabis use disorder (CUD, n = 954); and nonmedical prescription opioid use disorder (NMPOUD, n = 346) within a large nationally representative sample (n = 36,309), the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III). All diagnoses were based on in-person structured psychiatric interview (AUDADIS-5). SUD cases were compared alone and together to 3959 "super controls" who had neither a SUD nor a psychiatric disorder using an exome-focused array assaying 363,496 SNPs, yielding a representative view of within-disorder and cross-disorder genetic influences on SUDs. The 29 top susceptibility genes for one or more SUDs overlapped highly with genes previously implicated by GWAS of SUD. Polygenic scores (PGS) were computed within the European ancestry (EA) component of the sample (n = 12,505) using summary statistics from each of four clinically distinct SUDs compared to the 3959 "super controls" but then used for two distinctly different purposes: to predict SUD severity (mild, moderate, or severe) and to predict each of the other 3 SUDs. Our findings based on PGS highlight shared and unshared genetic contributions to the pathogenesis of SUDs, confirming the strong cross-inheritance of AUD and NUD as well as the distinctiveness of inheritance of opioid use disorder.
To present nationally representative findings on prevalence, sociodemographic correlates, disability, and comorbidity of narcissistic personality disorder (NPD) among men and women.
Face-to-face ...interviews with 34,653 adults participating in the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions conducted between 2004 and 2005 in the United States.
Prevalence of lifetime NPD was 6.2%, with rates greater for men (7.7%) than for women (4.8%). NPD was significantly more prevalent among black men and women and Hispanic women, younger adults, and separated/divorced/widowed and never married adults. NPD was associated with mental disability among men but not women. High co-occurrence rates of substance use, mood, and anxiety disorders and other personality disorders were observed. With additional comorbidity controlled for, associations with bipolar I disorder, post-traumatic stress disorder, and schizotypal and borderline personality disorders remained significant, but weakened, among men and women. Similar associations were observed between NPD and specific phobia, generalized anxiety disorder, and bipolar II disorder among women and between NPD and alcohol abuse, alcohol dependence, drug dependence, and histrionic and obsessive-compulsive personality disorders among men. Dysthymic disorder was significantly and negatively associated with NPD.
NPD is a prevalent personality disorder in the general U.S. population and is associated with considerable disability among men, whose rates exceed those of women. NPD may not be as stable as previously recognized or described in the DSM-IV. The results highlight the need for further research from numerous perspectives to identify the unique and common genetic and environmental factors underlying the disorder-specific associations with NPD observed in this study.
To present nationally representative data on 12-month and lifetime prevalence, correlates, and comorbidity of bipolar I disorder.
The data were derived from the 2001-2002 National Epidemiologic ...Survey on Alcohol and Related Conditions (N = 43,093). Prevalences and associations of bipolar I disorder with sociodemographic correlates and Axis I and II disorders were determined.
Prevalences of 12-month and lifetime DSM-IV bipolar I disorder were 2.0% (95% CI = 1.82 to 2.18) and 3.3% (95% CI = 2.76 to 3.84), respectively, and no sex differences were observed. The odds of bipolar I disorder were significantly greater among Native Americans, younger adults, and respondents who were widowed/separated/divorced and of lower socioeconomic status and significantly lower among Asians and Hispanics (p < .05). Men were significantly (p < .05) more likely to have unipolar mania and earlier onset and longer duration of manic episodes, while women were more likely to have mixed and major depressive episodes and to be treated for manic, mixed, and major depressive episodes. Bipolar I disorder was found to be highly and significantly related (p < .05) to substance use, anxiety, and personality disorders, but not to alcohol abuse.
Bipolar I disorder is more prevalent in the U.S. population than previously estimated, highlighting the underestimation of the economic costs associated with this illness. Associations between bipolar I disorder and Axis I and II disorders were all significant, underscoring the need for systematic assessment of comorbidity among bipolar I patients.
This study compared sociodemographic characteristics, adverse childhood experiences (ACEs), and substance use and psychiatric disorders between adolescent-limited (AL), adult-onset (AO), ...life-course-persistent (LP) and nonoffender (NO) groups using a large U.S. general population survey. The odds of experiencing several ACEs were greater among each offender group relative to NOs. LP offenders experience more ACEs than AL and AO offenders. Each offender group generally experienced greater substance use and psychopathology than NOs, whereas LP offenders experienced more substance use and psychopathology than AO and AL offenders. The results of this study identified several sociodemographic factors, ACEs, and types of psychopathology that differentiate AL, AO, LP, and NO offenders that can help inform prevention and intervention strategies designed to prevent offending and shorten criminal careers.
This study addressed the prevalences, correlates, co-morbidity and disability of DSM-IV generalized anxiety disorder (GAD) and other psychiatric disorders in a large national survey of the general ...population, the National Institute on Alcohol Abuse and Alcoholism's (NIAAA) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The study presents nationally representative data, for the first time, on prevalence, correlates, co-morbidity, and comparative disability of DSM-IV GAD.
Data are taken from a large (n=43093) representative sample of the adult USA population.R: Prevalences of 12-month and lifetime GAD were 2.1% and 4.1%. Being female, middle-aged, widowed/separated/divorced, and low income increased risk, while being Asian, Hispanic, or Black decreased risk. GAD was highly co-morbid with substance use, and other anxiety, mood, and personality disorders. Co-morbidity in GAD was not substantially greater than for most other Axis I and II disorders. Disability and impairment in pure GAD were equivalent to pure mood disorders, but significantly greater than in pure substance use, and other anxiety and personality disorders. Individuals co-morbid for GAD and each mood disorder were more disabled than those with pure forms of GAD or each mood disorder. When co-morbid with GAD, nicotine dependence and other anxiety and personality disorders were not associated with increased disability over that associated with pure GAD, but GAD did show increased disability over that due to each of these disorders in pure form.Conclusions. Associations between GAD and Axis I and II disorders were strong and significant, with variation among specific disorders. Results strongly support GAD as an independent disorder with significant impairment and disability.
To date, there have been no published data on 12-month comorbidity of DSM-IV alcohol and drug use disorders in the general U.S. population. The purposes of the present study were to examine the ...prevalence and comorbidity of alcohol and specific drug use disorders, and to identify sociodemographic and psychopathologic correlates and treatment seeking among three groups of respondents: (1) those with alcohol use disorders only; (2) those with drug use disorders only; (3) those with comorbid alcohol and drug use disorders.
Information on 12-month alcohol and specific drug use disorders in the United States was derived from face-to-face interviews in the National Institute on Alcohol Abuse and Alcoholism's (NIAAA) 2001–2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC:
n
=
43,093).
Prevalences were 7.35% for alcohol use disorders only, 0.90% for drug use disorder only and 1.10% for comorbid alcohol and drug use disorders. Sociodemographic and psychopathologic correlates of these three groups were quite different, with the drug use disorder and comorbid groups significantly more likely to be young, male, never married and of lower socioeconomic status than the alcohol use disorder only group. Associations between current alcohol use disorders and 25 specific drug use disorders were generally positive and statistically significant. The 12-month prevalence of treatment seeking significantly increased from 6.06% for those with an alcohol use disorder only to 15.63% for those with a drug use disorder only, and to 21.76% for those with comorbid alcohol and drug use disorders.
This study provides detailed data on the homotypic comorbidity of alcohol use disorders and 25 different drug use disorders and confirms the high levels of association seen in previous studies based on lifetime measures. Implications of this study are discussed in terms of integrating alcohol and drug treatment services and refining prevention and intervention efforts.
To present nationally representative data on 12-month and lifetime prevalence, correlates and comorbidity of social anxiety disorder (SAD) among adults in the United States as determined by the ...2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions.
Face-to-face survey.
The United States.
Adults (aged 18 and over) residing in households and group quarters (N = 43,093).
Prevalence and associations of SAD with sociodemographic and psychiatric correlates and Axis I and II disorders.
The prevalence of 12-month and lifetime DSM-IV SAD was 2.8% (95% CI = 2.5 to 3.1) and 5.0% (95% CI = 4.6 to 5.4), respectively. Being Native American, being young, or having low income increased risk, while being male, being of Asian, Hispanic, or black race/ethnicity, or living in urban or more populated regions reduced risk. Mean age at onset of SAD was 15.1 years, with a mean duration of 16.3 years. Over 80% of individuals with SAD received no treatment, and the mean age at first treatment was 27.2 years. Current and lifetime SAD were significantly related to other specific psychiatric disorders, most notably generalized anxiety, bipolar I, and avoidant and dependent personality disorders. The mean number of feared social situations among individuals with SAD was 7.0, with the majority reporting anxiety in performance situations.
Social anxiety disorder was associated with substantial unremitting course and extremely early age at onset. Social anxiety disorder often goes untreated, underscoring the need for health care initiatives geared toward increasing recognition and treatment. Comprehensive evaluation of patients with SAD should include a systematic assessment of comorbid disorders, and novel approaches to the treatment of comorbid SAD are needed.
Abstract Clinical and epidemiologic evidence has documented the significant associations between medical illnesses and psychiatric disorders. However, extensive research has focused on the ...comorbidity of medical conditions and depression, and most were cross sectional, focused on clinical samples, and grounded in DSM-III or DSM-III-R diagnostic criteria. The current prospective investigation examined associations among medical conditions at baseline and incident psychiatric disorders over a 3-year follow-up, using data from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Overall, the 3-year incidence rates of DSM-IV substance use, mood and anxiety disorders ranged from 0.65% (bipolar II) to 5.2% (alcohol abuse). Multiple regression analysis was conducted to examine the prospective physical–mental associations, while controlling for sociodemographic characteristics, psychological stress and health-related risk factors, and comorbid physical and psychiatric disorders. The present study represents, to our knowledge the largest population-based prospective study examining the physical–mental associations. Our results showed distinctly different patterns of comorbidity of medical illnesses with substance use, mood, and anxiety disorders. Stomach ulcer/gastritis, hypertension and arthritis emerged to be significant predictors of incident psychiatric disorders.
