Personality disorders evident by early adulthood and risk for anxiety disorders during middle adulthood

Data from the Children in the Community Study, a prospective longitudinal investigation, were used to investigate the association of personality disorder (PD) traits, evident by early adulthood, with risk for development of anxiety disorders by middle adulthood. Individuals without a history of anxiety disorders who met diagnostic criteria for >or=1 PD by early adulthood were at markedly elevated risk for agoraphobia, generalized anxiety disorder, obsessive-compulsive disorder, and panic disorder by middle adulthood. Antisocial, avoidant, borderline, dependent, depressive, histrionic, obsessive-compulsive, passive-aggressive, and schizotypal PD traits, evident by early adulthood, were associated with elevated risk for >or=1 anxiety disorder during middle adulthood. These associations remained significant after a history of anxiety disorder and co-occurring Axis I psychiatric disorder was controlled statistically. Findings of this study suggest that some types of PD traits that become evident by early adulthood may contribute to increased risk for the development of anxiety disorders by middle adulthood.     

Current affairs and the public psyche: American anxiety in the post 9/11 world

BACKGROUND: The most recent wave of interviews in a longitudinal study spanned the terrorist attacks of September 11, 2001. This unintended "natural experiment" allows examination of effects of traumatic events in ways impossible in studies conducted solely after the event and in populations not previously studied. METHODS: Participants were 610 members of the randomly selected Children in the Community cohort studied longitudinally for over 25 years and between ages 27 and 38 at the time of the current in-home interviews. Symptoms of generalized anxiety, post-traumatic stress disorder, panic disorder, agoraphobia, dissociation, and depression were assessed with an adaptation of the Structured Clinical Interview for Diagnosis. Changes in self-reported symptoms from an assessment 10 years earlier were related to the date of interview between 7/2001 and 12/2003 by polynomial regression methods, including demographic and design controls. Diagnoses based on clinical follow-up were also examined. RESULTS: In contrast to other data on this cohort where timing effects were absent, levels of symptoms were related to time of interview. The months following 9/11/2001 and the two anniversary periods in 2002 and 2003 showed significant elevation in anxiety symptoms (t = 2.50, df = 608, P = 0.013) with some evidence of elevated anxiety disorder as well (Fisher's exact test P = 0.096). Similar patterns were seen for specific anxiety and depressive symptom groups. Effects of religious participation, patriotism, having offspring, and media exposure on anxiety symptoms tended to differ by season, but the effect of community involvement did not. Proximity to New York City was not significantly related to symptoms. CONCLUSIONS: Study findings suggest that young Americans showed symptomatic and, possibly, diagnostic anxiety reactions to the events of 9/11 that persisted in response to heightened awareness of ongoing threat during anniversary periods.     

Heartland Virus Neutralizing Antibodies in Vertebrate Wildlife,United States, 2009–2014

Since its discovery in 2009, the tickborne Heartland virus (HRTV) has caused human illness in Missouri, Oklahoma, and Tennessee USA. To better assess the geographic distribution of HRTV, we used wildlife serology as an indicator. This retrospective evaluation determined that HRTV is widespread within the central and eastern United States.     

The Interplay Between Policy and COVID-19 Outbreaks in South Asia: Longitudinal Trend Analysis of Surveillance Data

BackgroundCOVID-19 transmission rates in South Asia initially were under control when governments implemented health policies aimed at controlling the pandemic such as quarantines, travel bans, and border, business, and school closures. Governments have since relaxed public health restrictions, which resulted in significant outbreaks, shifting the global epicenter of COVID-19 to India. Ongoing systematic public health surveillance of the COVID-19 pandemic is needed to inform disease prevention policy to re-establish control over the pandemic within South Asia.ObjectiveThis study aimed to inform public health leaders about the state of the COVID-19 pandemic, how South Asia displays differences within and among countries and other global regions, and where immediate action is needed to control the outbreaks.MethodsWe extracted COVID-19 data spanning 62 days from public health registries and calculated traditional and enhanced surveillance metrics. We use an empirical difference equation to measure the daily number of cases in South Asia as a function of the prior number of cases, the level of testing, and weekly shifts in variables with a dynamic panel model that was estimated using the generalized method of moments approach by implementing the Arellano–Bond estimator in R.ResultsTraditional surveillance metrics indicate that South Asian countries have an alarming outbreak, with India leading the region with 310,310 new daily cases in accordance with the 7-day moving average. Enhanced surveillance indicates that while Pakistan and Bangladesh still have a high daily number of new COVID-19 cases (n=4819 and n=3878, respectively), their speed of new infections declined from April 12-25, 2021, from 2.28 to 2.18 and 3.15 to 2.35 daily new infections per 100,000 population, respectively, which suggests that their outbreaks are decreasing and that these countries are headed in the right direction. In contrast, India’s speed of new infections per 100,000 population increased by 52% during the same period from 14.79 to 22.49 new cases per day per 100,000 population, which constitutes an increased outbreak.ConclusionsRelaxation of public health restrictions and the spread of novel variants fueled the second wave of the COVID-19 pandemic in South Asia. Public health surveillance indicates that shifts in policy and the spread of new variants correlate with a drastic expansion in the pandemic, requiring immediate action to mitigate the spread of COVID-19. Surveillance is needed to inform leaders whether policies help control the pandemic.

Associations of parental personality disorders and axis I disorders with childrearing behavior

Data from the Children in the Community Study, a community-based longitudinal investigation, were used to investigate the associations of parental anxiety, depressive, substance use, and personality disorders with parental child rearing behavior. Comprehensive psychosocial interviews, including assessments of child rearing, were conducted with 224 women and 153 men (mean age = 33 years; mean off- spring age = 8 years). Findings indicated that parental personality disorders were associated with parental possessiveness, inconsistent parental discipline, low parental communication, and low parental praise and encouragement. These associations remained significant when parental gender, offspring gender, and co-occurring parental disorders were controlled statistically. Parental anxiety disorders were independently associated with parental possessiveness. Parents with personality disorders were substantially more likely than parents without personality disorders to report engaging in multiple problematic child rearing behaviors. This association was not moderated by co-occurring parental disorders. These findings suggest that the presence of a parental personality disorder may be associated with an elevated likelihood of problematic parenting behavior during the child rearing years.     

Personality disorder traits associated with risk for unipolar depression during middle adulthood

Data from the Children in the Community Study, a prospective longitudinal investigation, were used to investigate the association of personality disorder (PD) traits, evident by early adulthood, with risk for the development of unipolar depressive disorders by middle adulthood. Antisocial, borderline, dependent, depressive, histrionic, and schizotypal PD traits, identified between ages 14 and 22, were significantly associated with risk for dysthymic disorder (DD) or major depressive disorder (MDD) by a mean age of 33 after a history of unipolar depression and other psychiatric disorder was controlled statistically. Individuals without a history of unipolar depression who met diagnostic criteria for > or =1 PD by a mean age of 22 were at elevated risk for DD or MDD by a mean age of 33 years. Individuals identified as having a DSM-IV Cluster A (paranoid, schizoid, or schizotypal) or Cluster C (avoidant, dependent, obsessive-compulsive) PD by a mean age of 22 years were at elevated risk for recurrent or chronic unipolar depression. The findings of this study suggest that some types of PD traits that become evident by early adulthood may contribute to an increased risk for the development or recurrence of unipolar depressive disorders by middle adulthood.
