A longitudinal examination of anxiety disorders and physical health conditions in a nationally representative sample of U.S. older adults

Beyond working hours: the association between long working hours, the use of work-related communication devices outside regular working hours, and anxiety symptoms

OBJECTIVES

The present study aimed to identify and compare the associations between long working hours and use of work-related communication devices outside regular working hours and anxiety symptoms, thereby providing insight into redefining working hours.

METHODS

Based on the cross-sectional data from the sixth Korean Working Conditions Survey (KWCS), specifically the responses from 46 055 workers, the use of work-related communication devices outside of regular working hours, long working hours, and anxiety symptoms were assessed. To investigate the associations between using work-related communication devices outside regular working hours or long working hours with anxiety symptoms, odds ratios (ORs) and 95% CIs were calculated using multiple logistic regression models.

RESULTS

Among 46 055 participants, 25 659 (55.7%) used work-related communication devices outside working hours, 8145 (17.7%) worked long hours, and 2664 (5.8%) experienced anxiety symptoms. Compared with the reference group, those who used work-related communication devices outside regular working hours without working long hours, had higher OR of anxiety symptoms (OR: 2.18; 95% CI, 1.97-2.41) than those who worked long hours without using work-related communication devices during off-hours (OR: 1.32; 95% CI, 1.09-1.59). Furthermore, the group that both worked long hours and used work-related communication devices outside working hours exhibited the highest OR of anxiety symptoms (OR: 2.57; 95% CI, 2.24-2.97).

CONCLUSIONS

Using work-related communication devices outside regular working hours is associated with a higher risk of anxiety symptoms compared with long working hours. This result suggests that using work-related devices outside regular working hours, in addition to regular work time, should be considered when redefining working hours.

Reappraising cognitive reappraisal: The taxing impact of emotion regulation on executive functioning in older adults

OBJECTIVE

Cognitive reappraisal (CR) and expressive suppression (ES) are two common emotion regulation strategies that share similar cognitive and neural underpinnings. Prior research has consistently shown that recent engagement in ES (both self-reported and experimentally manipulated) is associated with subsequent temporary decrements in executive functioning (EF). Thus far, only one study has examined the association between CR and EF, with null results. However, that study was limited by examining only zero-order correlations and by assessing only the speed, not accuracy, of EF performance. The present study examined multivariate relationships among recent CR, recent ES, and EF (both speed and accuracy), as well as the potential impacts of more chronic engagements in, and trait-level preferences between, the two emotion regulation strategies.

METHOD

Participants were 201 community-dwelling older adults aged 60 to 93 who had participated in three separate studies examining the relationship between self-reported emotion regulation and EF.

RESULTS

Recent CR was associated with EF performance accuracy above and beyond chronic CR. Both recent CR and ES contributed to EF performance accuracy uniquely beyond each other and beyond chronic and preferred emotion regulation.

CONCLUSIONS

Both recent ES and CR appear to have a deleterious impact on EF performance accuracy, potentially due to utilization of similar resources; both should be accounted for when assessing emotion regulation and its impacts on EF.

Risk factors for heightened COVID-19-Related anxiety among breast cancer patients

BACKGROUND

The COVID-19 pandemic has disrupted medical care, increased isolation, and exacerbated anxiety in breast cancer patients. Since March 2020, Breastcancer.org experienced a sustained surge in requested pandemic-related information and support. To characterize the pandemic-related experiences of breast cancer patients, we surveyed the Breastcancer.org Community early in the COVID-19 era.

METHODS

Breastcancer.org Community members were invited to complete an online questionnaire regarding their experience during the pandemic. Self-reported data on demographics, comorbidities, care disruptions, anxiety, coping ability, telemedicine use, and satisfaction with care were collected. Results were analyzed using Stata 16.0 (Stata Corp., Inc).

RESULTS

Included were 568 current and previous breast cancer patients, primarily with U.S. residence. Overall, 43.8% reported at least one comorbidity associated with severe COVID-19 illness and 61.9% experienced care delays. Moderate to extreme anxiety about contracting COVID-19 was reported by 36.5%, increasing with number of comorbidities (33.0% vs. 55.4%, p = 0.021), current breast cancer diagnosis (30.4% vs. 42.5%, p = 0.011), and poorer coping ability (15.5% vs. 53.9%, p < 0.0001). Moderate to extreme anxiety about cancer care disruptions was reported by 29.1%, increasing with current breast cancer diagnosis (19.1% vs. 38.9%, p < 0.0001), actual delayed care (18.9% vs. 35.3%, p < 0.0001), and poorer coping ability (13.1% vs. 57.7%, p < 0.0001). Most utilized telehealth and found it helpful, but also expressed increased anxiety and subjectively expressed that these were less preferable.

CONCLUSION

Early in the COVID-19 pandemic, anxiety was reported by a large proportion of breast cancer patients, with increased prevalence in those with risk factors. Attention to mental health is critical, as emotional distress not only harms quality of life but may also compromise outcomes.

[Anxiety Disorders in Rehabilitation]

Anxiety disorders are among the most common and socio-medically relevant mental illnesses. Correct diagnosis and initiation of appropriate therapy are of the utmost importance for patients' prognosis and for ensuring their social and occupational participation. This article therefore aims to provide an overview of new developments in the field of anxiety disorders relevant to rehabilitation.Within the framework of the changes in ICD-11, anxiety disorders now receive an independent chapter with a focus appropriate to their frequency and relevance. Further innovations concern the revised S3 guideline (2020) with the increasing consideration of digital therapy options, such as virtual reality exposure therapy (VER) as well as Internet-supported therapy methods as part of the therapy recommendations. Systemic therapy is also considered for the first time. However, the evidence for both procedures is significantly lower than for behavioral therapy, psychodynamic therapy, or pharmacotherapy. Online interventions are therefore not recommended as the sole therapy.Important for the practice in rehabilitation is the knowledge of the core symptoms of each of the above mentioned diagnoses as well as the diagnostic possibilities taking into account especially the correlations and interactions with physical diseases.Both psychotherapy and psychopharmacotherapy are available for treatment. In the field of psychotherapy, cognitive behavioral therapy (CBT) is the therapy of first choice due to the broadest base of evidence. In consideration of comorbid somatic diseases, attention must be paid to possible contraindications for antidepressants. Psychosomatic rehabilitation is an important resource in the overall treatment spectrum, especially if chronification or a threat to participation is foreseeable, in order to give the affected person confidence and motivation for further successful treatment of the anxiety disorder in an intensified treatment setting, in addition to teaching anxiety management strategies and socio-medical clarification. An important task of somatic rehabilitation is to recognize comorbid anxiety disorders and to provide the affected persons with an appropriate explanatory model of their complaints and to be able to initiate targeted treatment.

Associations between courses of posttraumatic stress disorder and physical health conditions among Canadian military personnel

BACKGROUND

Posttraumatic stress disorder (PTSD) and physical health conditions commonly co-occur and are both prevalent among military personnel. This study examined how courses of PTSD (no PTSD, remitted, new onset, persistent/recurrent) are associated with physical health conditions, among a population-based sample of Canadian military personnel.

METHOD

We analyzed data from the 2002 Canadian Community Health Survey-Mental Health and Well-being-Canadian Forces supplement (CCHS-CF) and the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-Up Survey (CAFVMHS; N = 2941). Multivariable logistic regressions examined associations between PTSD courses (reference = no PTSD) and physical health conditions.

RESULTS

In general, physical health conditions were more prevalent among symptomatic PTSD courses compared to no PTSD. After adjustment, new onset PTSD was associated with increased odds of all physical health conditions with the exception of ulcers and cancer (AOR range: 1.41-2.31) and remitted PTSD was associated with increased odds of diabetes (AOR = 2.31).

CONCLUSION

Results suggest that new onset PTSD may be most strongly associated with physical health conditions. Findings may inform targeted screening and intervention methods among military personnel with PTSD and physical health conditions.

Exploring the comorbidity between personality and musculoskeletal disorders among adults: A scoping review

INTRODUCTION

There is growing awareness of the comorbidity between mental and musculoskeletal disorders (MSDs) and their associated burden. We aimed to explore what is known regarding the existing epidemiological clinical-and population- based literature on the comorbidity between personality disorders (PDs) and MSDs specifically. In addition, we aimed to investigate their associated burden by examining a range of outcomes including morbidity/mortality, patient- and clinical-reported outcomes, work-related outcomes, hospital admissions, and financial costs. Finally, we sought to identify gaps in the literature and provide recommendations for further research.

METHODS

Studies with participants 15 years of age were eligible. Categorical PDs/features (DSM-III/IV/5 or ICD 9/10), identified by a health care professional, medical records, diagnostic interviews, or self-administered questionnaires. The definitions/groupings of MSDs were guided by the ICD-10 including conditions of the back, joints, and soft tissue, and disorders of bone density and structure. Published peer-reviewed and gray literature were considered. Eligible study designs were cohort, case-control, and cross-sectional studies, and existing reviews of observational studies. Identification and selection of articles, data extraction and the presentation of the results was conducted according to the Joanna Briggs Institute methodological guidance and the PRISMA extension for scoping reviews.

RESULTS

In total, 57 articles were eligible including 10 reviews and 47 individual studies. Across clinical and population settings, we detected evidence of comorbidity between PDs and chronic back/neck/spine conditions, arthritis, and fibromyalgia, and emerging evidence of associations between PDs and reduced bone mineral density. In terms of knowledge gaps, the burden associated with PDs and MSDs is poorly understood, as is their underlying mechanisms.

DISCUSSION

This scoping review might prompt further research into PDs and MSDs as separate groups of disorders, along with their comorbidity and the mechanisms that may link them.

Patient-Reported Outcomes of Yearly Imaging Surveillance in Patients Following Endovascular Aortic Aneurysm Repair

Little is known about the impact of standardized imaging surveillance on anxiety levels and well-being of patients after endovascular aortic aneurysm repair (EVAR). We hypothesize that patient anxiety levels increase just before receiving the imaging results compared with standard anxiety levels.

METHODS

Prospective cohort study from November 2018 to May 2020 including post-EVAR patients visiting the outpatient clinics of 4 Dutch hospitals for imaging follow-up. The Patient-Reported Outcomes Measurement Information System (PROMIS) was used. Patients completed the PROMIS Anxiety v1.0 Short Form (SF) 4a, PROMIS-Global Health Scale v1.2, and PROMIS-Physical Function v1.2 SF8b at 2 time points: prior to the result of the imaging study (T1: pre-visit) and 6-8 months later (T2: reference measurement). Mean T-scores at T1 were compared to T2, and T2 to the general 65+ Dutch population.

RESULTS

Altogether 342 invited patients were eligible, 214 completed the first questionnaire, 189 returned 2 completed questionnaires and 128 patients did not participate. Out of 214 respondents, 195 were male (91.1%) and the mean (standard deviation) age was 75.2 (7.0) years. There were no significant differences between T1 and T2 in anxiety levels (0.48; 95% confidence interval[CI] -0.42-1.38), global mental health (0.27; 95% CI -0.79-0.84), global physical health (0.10; 95% CI -0.38-1.18) and physical function (0.53; 95% CI -0.26-1.32). Compared with the 65+ Dutch population, at T2 patients experienced more anxiety (3.8; 95% CI 2.96-5.54), had worse global physical health (-3.2; 95% CI -4.38 - -2.02) and physical function (-2.4; 95% CI -4.00 - -0.80). Global mental health was similar (-1.0; 95% CI -2.21 - 0.21).

CONCLUSIONS

Post-EVAR patients do not experience more anxiety just before receiving surveillance imaging results than outside this period, but do suffer from more anxiety and worse physical outcomes than the 65+ Dutch population.

The association between chronic pain conditions and subclinical and clinical anxiety among community-dwelling older adults consulting in primary care

OBJECTIVE

To examine associations between chronic pain conditions, pain level, and subclinical/clinical anxiety in community-dwelling older adults.

DESIGN

Cross-sectional associations were analyzed using multinomial logistic regression to compare the odds of having subclinical/clinical anxiety by painful condition and pain level, controlling for confounders.

SETTING

Participants were recruited in primary care waiting rooms to take part in the first wave of the Étude sur la Santé des Aînés (ESA)-Services study.

SUBJECTS

1608 older adults aged 65+.

METHODS

Clinical anxiety was assessed using DSM-IV criteria. Subclinical anxiety was considered present when participants endorsed symptoms of anxiety but did not fulfill clinical diagnostic criteria for an anxiety disorder. Painful chronic conditions included arthritis, musculoskeletal conditions, gastrointestinal problems, and headaches/migraines. Presence of painful conditions was assessed using combined self-report and health administrative data sources. Pain level was self-reported on an ordinal scale. Physical comorbidities were identified from ICD-9/10 diagnostic codes and depression was evaluated based on the DSM-IV.

RESULTS

Sixty-six percent of home-living older adults suffer from a chronic pain condition. Older adults with clinical anxiety are more likely to experience musculoskeletal pain, gastrointestinal problems, headaches/migraines, and higher pain levels compared to those with no anxiety. Also, those with ≥3 painful conditions are at greater risk for subclinical and clinical anxiety compared to those with no painful condition.

CONCLUSIONS

These results emphasize the need for assessing anxiety symptoms in older adults with chronic pain conditions. Comprehensive management of comorbid chronic pain and psychopathology might help reduce the burden for patients and the healthcare system.

Associations Between Anxiety Symptoms and Health-Related Quality of Life: A Population-Based Twin Study in Sri Lanka

Anxiety not only concerns mental wellbeing but also negatively impacts other areas of health. Yet, there is limited research on (a) the genetic and environmental aetiology of such relationships; (b) sex differences in aetiology and (c) non-European samples. In this study, we investigated the genetic and environmental variation and covariation of anxiety symptoms and eight components of health-related quality of life (QoL), as measured by the short form health survey (SF-36), using genetic twin model fitting analysis. Data was drawn from the Colombo Twin and Singleton Study (COTASS), a population-based sample in Sri Lanka with data on twins (N = 2921) and singletons (N = 1027). Individual differences in anxiety and QoL traits showed more shared environmental (family) effects in women. Men did not show familial effects. Anxiety negatively correlated with all eight components of QoL, mostly driven by overlapping unique (individual-specific) environmental effects in both sexes and overlapping shared environmental effects in women. This is the first study in a South Asian population supporting the association between poor mental health and reduced QoL, highlighting the value of integrated healthcare services. Associations were largely environmental, on both individual and family levels, which could be informative for therapy and intervention.

Associations between physical health conditions and posttraumatic stress disorder according to age

OBJECTIVES

Posttraumatic stress disorder (PTSD) is associated with various physical health conditions. However, it is unclear whether the relationship between PTSD and physical health conditions differs according to age. This study aims to examine the associations between PTSD and physical health conditions across four adult age categories.

METHODS

We analyzed data from the 2012 to 2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309). The Alcohol Use Disorder and Associated Disabilities Interview Schedule-5 assessed past-year DSM-5 PTSD. Multiple regression analyses examined associations between PTSD (reference = no PTSD) with number and type of physical health conditions in each age category (18-34: "younger adults," 35-49: "middle-aged adults," 50-64: "young-old adults," 65+: "older adults").

RESULTS

The prevalence of nearly all physical health conditions increased according to age, whereas the prevalence of PTSD tended to decrease with age. After adjustment, PTSD was associated with a greater number of physical health conditions among all age categories (b range: 0.62-1.29). Regardless of age category, PTSD was associated with increased odds of cardiovascular and musculoskeletal conditions (AOR range: 1.54-2.34). PTSD was also associated with increased odds of gastrointestinal, hepatobiliary, endocrine/metabolic, respiratory, neurologic conditions, cancer, sleep disorders, and anemia among select age categories (AOR range: 1.70-3.31). For most physical health conditions, the largest effect sizes emerged for younger and middle-aged adults.

CONCLUSIONS

PTSD is associated with many physical health conditions across the age spectrum, particularly among younger and middle-aged adults. Results may inform targeted screening and intervention strategies to mitigate risk of physical health conditions among adults with PTSD.

Higher Anxiety Is Associated with Lower Cardiovascular Autonomic Function in Female Twins

Anxiety symptoms co-occur with cardiovascular health problems, with increasing evidence suggesting the role of autonomic dysfunction. Yet, there is limited behavior genetic research on underlying mechanisms. In this twin study, we investigated the phenotypic, genetic and environmental associations between a latent anxiety factor and three cardiovascular autonomic function factors: interbeat interval (IBI, time between heart beats), heart rate variability (HRV, overall fluctuation of heart-beat intervals) and baroreflex sensitivity (BRS, efficiency in regulating blood pressure [BP]). Multivariate twin models were fit using data of female twins (N = 250) of the Twin Interdisciplinary Neuroticism Study (TWINS). A significant negative association was identified between latent anxiety and BRS factors (r = -.24, 95% CI [-.40, -.07]). Findings suggest that this relationship was mostly explained by correlated shared environmental influences, and there was no evidence for pleiotropic genetic or unique environmental effects. We also identified negative relationships between anxiety symptoms and HRV (r = -.17, 95% CI [-.34, .00]) and IBI factors (r = -.13, 95% CI [-.29, .04]), though these associations did not reach statistical significance. Findings implicate that higher anxiety scores are associated with decreased efficiency in short-term BP regulation, providing support for autonomic dysfunction with anxiety symptomatology. The baroreflex system may be a key mechanism underlying the anxiety-cardiovascular health relationship.

Anxiety Disorders in Patients With Somatic Diseases

OBJECTIVE

Anxiety disorders are among the most frequent mental disorders and are associated with a range of short- and long-term impairments and disabilities. Relatively little is known about anxiety disorders in patients with somatic diseases, and the present literature review highlights the current research in this field, data about prevalences of anxiety disorders in patients with somatic diseases, and the effectiveness of interventions. This article also introduces a comprehensive model of inpatient treatment and summarizes the evidence pertinent to this approach.

METHODS

A narrative review is presented with regard to prevalence and treatment of anxiety disorders in patients with somatic diseases. The effects of inpatient treatment are illustrated based on a case report.

RESULTS

This review indicates that anxiety disorders are more common in patients with somatic diseases, with prevalence estimates ranging from 2.5% to 55%, than in the general population. Several outpatient treatment options exist, with substantial support for the effectiveness of cognitive behavioral therapy, psychodynamic therapy, and pharmacotherapy. We also provide evidence in support of psychosomatic inpatient treatment for patients with anxiety disorders that are comorbid with somatic diseases.

CONCLUSIONS

Anxiety disorders are common in patients with somatic diseases, and several effective treatment options exist, including cognitive behavioral therapy and pharmacological interventions. We also provide support for the effectiveness of inpatient treatment with unique opportunities for multidisciplinary psychosomatic treatment of anxiety disorders with comorbid somatic diseases.

Physical health comorbidities in women with personality disorder: Data from the Geelong Osteoporosis Study

Background

Associations between common psychiatric disorders, psychotic disorders and physical health comorbidities are frequently investigated. The complex relationship between personality disorders (PDs) and physical health is less understood, and findings to date are varied. This study aims to investigate associations between PDs with a number of prevalent physical health conditions.

Methods

This study examined data collected from women (n = 765; ≥ 25 years) participating in a population-based study located in south-eastern Australia. Lifetime history of psychiatric disorders was assessed using the semi-structured clinical interviews (SCID-I/NP and SCID-II). The presence of physical health conditions (lifetime) were identified via a combination of self-report, medical records, medication use and clinical data. Socioeconomic status, and information regarding medication use, lifestyle behaviors, and sociodemographic information was collected via questionnaires. Logistic regression models were used to investigate associations.

Results

After adjustment for sociodemographic variables (age, socioeconomic status) and health-related factors (body mass index, physical activity, smoking, psychotropic medication use), PDs were consistently associated with a range of physical health conditions. Novel associations were observed between Cluster A PDs and gastro-oesophageal reflux disease (GORD); Cluster B PDs with syncope and seizures, as well as arthritis; and Cluster C PDs with GORD and recurrent headaches.

Conclusions

PDs were associated with physical comorbidity. The current data contribute to a growing evidence base demonstrating associations between PDs and a number of physical health conditions independent of psychiatric comorbidity, sociodemographic and lifestyle factors. Longitudinal studies are now required to investigate causal pathways, as are studies determining pathological mechanisms.

Associations of PTSD, chronic pain, and their comorbidity on cannabis use disorder: Results from an American nationally representative study

BACKGROUND

Cannabis can be prescribed for posttraumatic stress disorder (PTSD) and chronic pain, and comorbid cannabis use disorder (CUD) can occur in both conditions. Research demonstrates that PTSD and chronic pain commonly co-occur.

METHODS

Data were acquired from the National Epidemiologic Survey on Alcohol and Related Conditions-III (N = 36,309). Past-year CUD and PTSD were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-5. Past-year physician-confirmed chronic pain was self-reported and classified as musculoskeletal (e.g., arthritis), digestive (e.g., pancreatitis), and nerve (e.g., reflex sympathetic dystrophy) pain. Weighted cross-tabulations assessed sociodemographic, psychiatric, and chronic pain condition variables among those with PTSD versus no PTSD, among the entire sample and among those with CUD and chronic pain. Multiple logistic regressions examined the relationship between PTSD and chronic pain with CUD. CUD characteristics were also evaluated across PTSD and chronic pain groups.

RESULTS

Rates of CUD were elevated in PTSD (9.4%) compared to those without (2.2%). The odds of CUD were greater for PTSD+digestive pain, PTSD+nerve pain, and PTSD+any chronic pain compared to having neither PTSD nor chronic pain (odds ratio range: 1.88-2.32). PTSD with and without comorbid chronic pain was associated with overall elevated rates of adverse CUD characteristics, including earlier age of onset, greater usage, and greater CUD severity.

CONCLUSIONS

PTSD with and without chronic pain is associated with elevated rates and severity of CUD. These results may have implications for prescribing practices and understanding individuals at risk for developing CUD.

Understanding the association between posttraumatic stress disorder characteristics and physical health conditions: A population-based study

Posttraumatic stress disorder (PTSD) is commonly comorbid with a range of physical health conditions. The aim of this study was to examine the association between index trauma and PTSD symptom clusters with physical health conditions, among individuals with PTSD in a population-based sample. Data were analyzed from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III; N = 36,309). Past-year PTSD (n = 1779) was assessed using a clinical interview in accordance with DSM-5 criteria. Multiple logistic regression models examined the associations between PTSD symptom clusters and index trauma with physical health conditions. Results of the most stringent model, adjusting for sociodemographics, other psychiatric conditions, and other PTSD symptom clusters, indicated re-experiencing symptoms were associated with cardiovascular and endocrine/metabolic conditions (adjusted odds ratio (AOR) range: 1.18-1.33) and negative alterations in mood and cognition symptoms were associated with sleep disorder (AOR = 1.16, 95% confidence interval (CI) [1.04-1.30], p = .009). Results also demonstrated significant associations between life-threatening illness with cancer, digestive, and neurologic conditions (AOR range: 2.10-3.42) and life-threatening injury with musculoskeletal and neurologic conditions (AOR range: 1.76-2.04). Finally, significant associations emerged between psychological trauma with musculoskeletal and neurologic conditions (AOR range: 0.48-0.66), and other trauma with digestive conditions and anemia (AOR range: 0.38-0.47). Results suggest PTSD symptomatology and index trauma play a differential role in their association with variable physical health conditions. Results may inform screening practices and targeted interventions to mitigate risk of PTSD and physical health conditions.

Long-term quality of life in patients with vestibular schwannoma managed with microsurgery

OBJECTIVE

Little is known about the long term (greater than 10 years) quality of life in patients with vestibular schwannoma. This study aimed to evaluate long-term outcomes in patients with vestibular schwannoma.

METHOD

A retrospective cohort study was performed across 2 academic institutions, with patients followed at least 10 years after vestibular schwannoma surgery (2000 to 2007). Telephone interviews were used to assess quality of life using the Glasgow Benefit Inventory and short form 12 item (version 2) health survey.

RESULTS

A total of 99 out of 110 patients were included. Increasing age and symptom burden were associated with poorer quality of life (p = 0.01 and 0.02, respectively). The presence of imbalance, headache and facial nerve dysfunction were all associated with poorer quality of life scores (p = 0.01, 0.04 and 0.02, respectively).

CONCLUSION

Identifying and managing post-operative symptoms may improve quality of life in vestibular schwannoma patients and can guide clinical decision making.

Comparing anxiety and depression to obesity and smoking as predictors of major medical illnesses and somatic symptoms

OBJECTIVE

Anxiety and depression predict poor physical health longitudinally, but are neglected in primary care settings compared to other risk factors such as obesity and smoking. Further, anxiety has been less commonly studied than depression, and whether anxiety has unique predictive effects for physical health is unknown. We compared anxiety and depression to obesity and smoking as predictors of physical health indices and examined unique predictive effects of anxiety and depression.

METHOD

Using data from the Health and Retirement study, a US population-based cohort study of older adults, we tested longitudinal associations of anxiety and depression symptoms with onset of self-reported physical health indices (N = 15,418; M age = 68). Medical illnesses (heart disease, stroke, arthritis, high blood pressure, diabetes, and cancer) and somatic symptoms (stomach problems, shortness of breath, dizziness, back pain, headache, pain, and eyesight difficulties) were assessed on two occasions over four years. Anxiety and depression were measured at the initial time point and tested as predictors of medical illness and somatic symptom onset.

RESULTS

Anxiety and depression symptoms predicted greater incidence of nearly all medical illnesses and somatic symptoms. Effects were as strong as or stronger than those of obesity and smoking, and anxiety and depression independently increased risk for most physical health indices assessed.

CONCLUSIONS

Findings suggest that anxiety and depression are as strongly predictive of poor future physical health as obesity and smoking and that anxiety is independently linked to poor physical health. Greater attention should be paid towards these conditions in primary care. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Maladaptive Eating in Posttraumatic Stress Disorder: A Population-Based Examination of Typologies and Medical Condition Correlates

Posttraumatic stress disorder (PTSD) and eating pathology are frequently comorbid, and both are independent risk factors for various medical conditions. Using population-based data collected as part of the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III; N = 36,309), the primary objectives of this study were to (a) identify eating pathology classes among PTSD and (b) investigate associations between maladaptive eating and medical conditions among PTSD. Using the Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS-5), we assessed PTSD and maladaptive eating symptoms in accordance with the DSM-5. We used a latent class analysis to identify maladaptive eating typologies among adults with lifetime PTSD (n = 2,339; 6.1%) and multivariable logistic regression models to examine associations between each of the six emergent maladaptive eating typologies and medical conditions. Results revealed that over 40% of individuals with PTSD endorsed indicators of maladaptive eating. In addition, each maladaptive eating typology among PTSD was significantly associated with unique sociodemographic characteristics and increased odds of medical conditions relative to no PTSD and no eating disorder, adjusted odds ratios (AORs) = 1.34-6.55, and PTSD with no eating psychopathology, AORs = 1.43-5.11. Results of this study provide a better understanding of maladaptive eating in adults with PTSD and potential medical sequelae. Results indicate maladaptive eating may be an important mechanism in the association between PTSD and medical conditions, which may inform targeted interventions among individuals with these comorbidities.

Posttraumatic stress disorder and chronic pain are associated with opioid use disorder: Results from a 2012-2013 American nationally representative survey

BACKGROUND

Chronic pain conditions and posttraumatic stress disorder (PTSD) commonly co-occur and are associated with opioid use disorder (OUD). The aims of this paper were to identify prevalence estimates of OUD among individuals with and without PTSD and assess independent and combined contributions of PTSD and chronic pain conditions on OUD in a nationally representative sample.

METHODS

Data were extracted from 36,309 individuals from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions. Past-year PTSD and OUD were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-5 edition. Respondents reported physician-confirmed, past-year chronic pain conditions, categorized into musculoskeletal pain (e.g., arthritis), digestive pain (e.g., pancreatitis), and nerve pain (e.g., reflex sympathetic dystrophy). We examined the weighted prevalence of OUD among those with and without PTSD. Multiple logistic regressions examined the association between PTSD and chronic pain conditions on OUD.

RESULTS

The prevalence of OUD was higher among those with PTSD than those without. Comorbid PTSD/musculoskeletal pain and PTSD/nerve pain conditions were associated with increased odds of OUD, compared to those with neither PTSD nor chronic pain conditions. Digestive pain conditions were not associated with OUD. Comorbid PTSD/musculoskeletal pain conditions demonstrated an additive relationship on OUD compared to musculoskeletal pain conditions and PTSD alone.

CONCLUSIONS

Results reveal that musculoskeletal pain and nerve pain conditions are associated with increased odds of OUD, but only musculoskeletal pain conditions display an additive relationship on OUD when combined with PTSD. These findings have implications for opioid management and screening among those with comorbid conditions.

Comorbidity in illness-induced posttraumatic stress disorder versus posttraumatic stress disorder due to external events in a nationally representative study

OBJECTIVE

The current study compared physical and mental health characteristics and quality of life of illness-induced posttraumatic stress disorder (PTSD) versus those with PTSD due to external traumatic events in a population-based sample.

METHOD

PTSD was assessed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS-5) using DSM-5 criteria in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions. Participants with past-year PTSD (n = 1779) were categorized into two groups: illness-induced (6.5%) and other trauma-induced PTSD (92.9%) based on index trauma. Group differences in physical health, mental health, and quality of life were estimated using multiple logistic and linear regressions with adjustment for demographics and medical morbidity.

RESULTS

Compared to PTSD due to external events, illness-induced PTSD had higher rates of life-threatening illness in the past year. Illness-induced PTSD compared to PTSD due to external events was associated with reduced odds of depressive/bipolar disorders and antisocial personality disorder, but increased odds of cannabis use disorder. The groups did not differ on quality of life after accounting for medical morbidity.

CONCLUSION

Illness-induced PTSD is common among American adults and has a similar impact on quality of life as PTSD due to external events, but may have distinct mental health correlates.

Physical comorbidities increase the risk of psychiatric comorbidity in immune-mediated inflammatory disease

OBJECTIVE

We tested the association between physical comorbidity and incident depression, anxiety disorder and bipolar disorder in three immune-mediated inflammatory diseases (IMID): inflammatory bowel disease (IBD), multiple sclerosis (MS) and rheumatoid arthritis (RA) versus age-, sex- and geographically-matched controls.

METHODS

Using population-based administrative data we identified 6119 persons with IBD, 3514 persons with MS, 10,206 persons with RA and 97,727 matched controls. We identified incident cases of depression, anxiety disorder and bipolar disorder in these populations. We evaluated the association of physical comorbidities with incident psychiatric comorbidity using Cox regression, adjusting for sociodemographic factors and index year.

RESULTS

The risk of incident depression, anxiety disorders and bipolar disorder was higher in each IMID cohort versus their matched cohorts. The risk of incident psychiatric comorbidity increased with an increasing number of physical comorbidities for each psychiatric comorbidity evaluated, across all IMID. Adjustment for physical comorbidity did not attenuate the increased risk of psychiatric comorbidity in the IMID cohorts versus their matched cohorts.

CONCLUSION

The increased incidence of psychiatric comorbidity in IMID versus matched general population cohorts is not accounted for by their increased prevalence of physical comorbidities. However, within IMID cohorts, physical comorbidity increases the risk of psychiatric comorbidity.

Epidemiology of gastrointestinal symptoms in young and middle-aged Swiss adults: prevalences and comorbidities in a longitudinal population cohort over 28 years

Background

Although subacute and chronic gastrointestinal symptoms are very common in primary care, epidemiological date are sparse. The aim of the study was to examine and quantify the prevalence of subacute and chronic gastrointestinal symptoms and their associations with somatic and mental disorders in the general population.

Methods

Data were collected prospectively between 1981 (age m = 22, f = 23) and 2008 (age 49/50) from the Zurich Cohort Study (n = 292 men, 299 women), a representative general population survey. The participants were assessed using a semi-structured interview, the “Structured Psychopathological Interview and Rating of the Social Consequences of Psychological Disturbances for Epidemiology” (SPIKE). Prevalence rates were computed to be representative of the general population aged 22–50. Associations were quantified by odds ratios (ORs) and their 99% confidence intervals (CI).

Results

The prevalences of intestinal and of gastric symptoms were significantly higher among women in all categories examined. For example, any gastric symptoms: f. 26.4% vs m.15.2%; any intestinal symptoms: 27.6% vs 14.6%; nausea/vomitus: 19.1% vs 4.5%; constipation: 15.8% vs 6.5% (all p < 0.001). Strong associations (all p < 0.0001) were found between fatigue (1 month) and chronic stomach (OR = 9.96, 99%-CI: 5.53–17.94) and chronic intestinal symptoms (OR = 9.02, 99%-CI: 4.92–16.54). Panic attacks were associated with subacute intestinal symptoms (OR = 4.00, 99%-CI: 2.43–6.59). Anxiety was more strongly associated with subacute intestinal symptoms (OR = 3.37, 99%-CI: 2.23–5.08) than with subacute stomach symptoms (OR = 1.85, 1.20–2.86). Bipolar disorders were associated with subacute stomach symptoms (OR = 1.83, 1.18–2.17) and unipolar depression with subacute intestinal symptoms (OR = 2.05, 1.34–3.15).

Conclusions

Remarkably high prevalence rates of gastric and intestinal complaints were observed in women (over 1/4; men 1/7). Fatigue/neurasthenia was the strongest co-factor in both conditions. Various syndromes related to anxiety, phobia, and panic disorders showed further significant associations. The integration of psychiatric and/or psychological treatment could help address the functional part of gastric and intestinal syndromes.

[Psychotherapy for posttraumatic stress disorder in older adults]

BACKGROUND

In contrast to the high demographic relevance of the older population, relatively little is known about prevalence rates, the typologies/symptom profiles and effective therapeutic approaches for posttraumatic stress disorder (PTSD) in older adults.

AIM

The aim of the present article is to provide an overview of prevalence rates, typologies of PTSD and effective treatment approaches for PTSD in the elderly.

RESULTS

Compared to younger cohorts, the group of older people has a markedly lower PTSD prevalence in the vast majority of epidemiological studies. There is a comparable structure over all age classes (i. e. classes with low, moderate and high symptoms) with respect to the symptom profile of PTSD. There are currently only a few controlled treatment studies for the cohort of older adults. The published controlled or randomized controlled interventional studies suggest that trauma-focused and narrative approaches seem to be effective in the treatment of PTSD in the elderly.

CONCLUSION

Future research should take account of the results so far in order to verify the existing preliminary results and to deal with current limitations. Randomized controlled trials are required, which should include a heterogeneous sample of elderly people and examine different therapeutic approaches in their effectiveness and feasibility in this cohort.

Efficacy and Feasibility of a Therapist-Guided Internet-Based Intervention for Older Persons with Childhood Traumatization: A Randomized Controlled Trial

OBJECTIVE

Although cognitive-behavioral treatment approaches for post-traumatic stress disorder (PTSD) exist, only a small proportion of older adults seeks psychological treatment. Alternative treatment approaches are thus needed to fill the gap between provision and use of psychological interventions. This study aimed to investigate the efficacy and feasibility of an Internet-based, therapist-guided cognitive-behavioral therapy (Internet-based CBT) for older individuals with PTSD symptoms.

METHODS

Patients with clinically meaningful (i.e., subsyndromal or greater) PTSD symptoms were randomly assigned to a 6-week treatment group of therapist-guided Internet-based CBT (N = 47; treatment group) or a wait-list group (N = 47; WL). The treatment group was assessed pre- and post-treatment as well as at 3-, 6- and 12-month follow-ups.

RESULTS

Linear mixed-effects analyses showed a significant interaction between group (treatment versus WL) and time (pre versus post) for PTSD symptoms with a moderate between-group effect size in favor of the treatment group (d = 0.42). Effects in the treatment group were maintained up to the 12-month follow-up. Findings indicate a significant interaction (group × time) for quality of life (d = 0.39) and self-efficacy (d = 0.38). With regard to the feasibility, attrition rate was very low in both groups (treatment group: 12.8%, WL: 6.4%) and working alliance was very high.

CONCLUSIONS

Results suggest that therapist-guided Internet-based CBT is associated with a substantial reduction in PTSD symptoms, and increase in resource-related variables in older adults with (subsyndromal) PTSD. This Internet-based intervention may offer a promising option in a stepped-care approach for older trauma-affected persons who may otherwise not pursue mental health treatment.

Impact of Anxiety and Depression on Physical Health Condition and Disability in an Elderly Korean Population

OBJECTIVE

This study aimed to investigate the longitudinal effects of anxiety, depression, and their comorbidity on physical disorders and disability in an elderly Korean population.

METHODS

In total, 1,204 community-dwelling elders were evaluated at baseline, and of these 909 (75%) were re-assessed two years later. Anxiety and depression were identified at baseline using questions from the community version of the Geriatric Mental State diagnostic schedule (GMS-B3). Participants were assessed for functional disability and for 11 physical disorders both at baseline and at follow-up.

RESULTS

Anxiety alone was associated with the incidence of heart disease, depression alone with the incidence of asthma, and comorbid anxiety and depression with incidence of eyesight problem, persistent cough, asthma, hypertension, heart disease, and gastrointestinal problems. Comorbid anxiety and depression were associated with an increase in the number of physical disorders and the degree of disability during the two-year follow-up, compared to anxiety or depression alone or the absence of anxiety or depression.

CONCLUSION

Anxiety, depression, and particularly their comorbidity should be assessed in the elderly population considering their longitudinal effects on physical disorders and disability. Future study is required to determine whether interventions aimed at these disorders can mitigate their impacts.

Relative Association of Multi-Level Supportive Environments on Poor Health among Older Adults

Background: The aging of the United States population poses significant challenges to American healthcare and informal caregiving systems. Additional research is needed to understand how health promotion programs and policies based on a socio-ecological perspective impact the health and well-being of older persons. The purpose of this study was to investigate personal characteristics and supportive environments associated with poor health among older individuals aged 65 and over. Methods: This study used a cross-sectional design and was guided by a conceptual framework developed by the authors to depict the relationship between personal characteristics and environments associated with poor health status. Environment types included in this study were family, home, financial, neighborhood, and healthcare. The sample was comprised of 1319 adults aged 65 years and older residing in Central Texas. From a random selection of households, participants were administered a mail-based survey created by a community collaborative effort. Descriptive statistics and three binary logistic regression models were fitted to examine associations with poor health status (i.e., physical, mental, and combined physical/mental). Results: Two personal characteristics (number of chronic conditions and educational level) were consistently related (p < 0.05) to health outcomes. Supportive family, home, financial, neighborhood, and health care environmental factors were shown to be related (p < 0.05) to various aspects of physical or mental health outcomes. Conclusions: Multidimensional factors including personal characteristics and protective environments are related to health status among older individuals. The unique roles of each environment can help inform public health interventions to create and enhance support for older adults to engage in healthful activities and improve their physical and mental health.

Anxiety Disorders and General Medical Conditions: Current Research and Future Directions

Evidence that anxiety disorders are associated with general medical conditions is growing. While it is known that medical and mental conditions are often comorbid, research demonstrates that there may be underlying causal mechanisms. Furthermore, comorbid anxiety and general medical conditions are associated with poorer patient outcomes than either condition alone. Comorbid general medical and mental disorders not only affect individual patient health but also strain existing medical systems. Growing health care expenditures and increasing time pressures on clinicians create a challenging environment for intensive therapy in traditional settings. Effective screening, diagnosis, and treatment of individuals with comorbid conditions require health systems that are based on interprofessional collaboration, including integrative and collaborative care services. These models encourage the provision of patient care within a network of health care professionals, working together and sharing expertise for more efficient and holistic care. Research on the design and implementation of these systems within the context of anxiety disorders and comorbid general medical conditions is in its infancy. Given the staggeringly high rates of anxiety disorders within the general population and the continued rise of many chronic medical conditions coinciding with the increasing lifespan, mental health and primary care providers should consider how they might implement integrative care methods within their own practice.

Mental health service use among older Canadians with anxiety and comorbid physical conditions

OBJECTIVES

The objective of this study was to understand the relationship between mental health service use and comorbid any anxiety and commonly occurring physical conditions (i.e., arthritis, cardiovascular disease, and gastrointestinal disease) in a national sample of older Canadians.

METHODS

The sample consisted of older adults aged 55 years and older from the Canadian Community Health Survey 1.2 (N = 12,792). Trained lay interviewers assessed mental disorders based on Diagnostic and Statistical Manual of Mental Disorders - 4th Edition (DSM-IV) criteria. Physical conditions were based on self-reported diagnoses by health professionals. Past-year mental health service use was categorized into whether services were utilized in the general or specialty sectors. Crosstabulations and multiple logistic regressions examined the effects of both anxiety and physical conditions on mental health service use within the general and specialty mental health sectors.

RESULTS

Adjusted logistic regressions indicated that there was no effect of anxiety among older adults with gastrointestinal disease on mental health service use. Conversely, in adjusted regressions, having a comorbid anxiety disorder with cardiovascular disease or arthritis was associated with increased odds of service use from the general sector in comparison to cardiovascular disease and arthritis, respectively, alone. Additionally, older adults with comorbid any anxiety disorder and gastrointestinal disease in comparison to anxiety alone had lower rates of seeking mental health services; however, these effects were no longer significant in an adjusted model.

CONCLUSION

Comorbidity between gastrointestinal conditions and anxiety was associated with unmet mental health service needs. This may be conceptualized in the context overlapping symptomatology in gastrointestinal conditions and anxiety.

Post-traumatic stress disorder and cardiometabolic disease: improving causal inference to inform practice

Post-traumatic stress disorder (PTSD) has been declared 'a life sentence' based on evidence that the disorder leads to a host of physical health problems. Some of the strongest empirical research - in terms of methodology and findings - has shown that PTSD predicts higher risk of cardiometabolic diseases, specifically cardiovascular disease (CVD) and type 2 diabetes (T2D). Despite mounting evidence, PTSD is not currently acknowledged as a risk factor by cardiovascular or endocrinological medicine. This view is unlikely to change absent compelling evidence that PTSD causally contributes to cardiometabolic disease. This review suggests that with developments in methods for epidemiological research and the rapidly expanding knowledge of the behavioral and biological effects of PTSD the field is poised to provide more definitive answers to questions of causality. First, we discuss methods to improve causal inference using the observational data most often used in studies of PTSD and health, with particular reference to issues of temporality and confounding. Second, we consider recent work linking PTSD with specific behaviors and biological processes, and evaluate whether these may plausibly serve as mechanisms by which PTSD leads to cardiometabolic disease. Third, we evaluate how looking more comprehensively into the PTSD phenotype provides insight into whether specific aspects of PTSD phenomenology are particularly relevant to cardiometabolic disease. Finally, we discuss new areas of research that are feasible and could enhance understanding of the PTSD-cardiometabolic relationship, such as testing whether treatment of PTSD can halt or even reverse the cardiometabolic risk factors causally related to CVD and T2D.

Mental-Physical Comorbidity in Korean Adults: Results from a Nationwide General Population Survey in Korea

OBJECTIVE

The aims of this study were to estimate the prevalence of mental-physical comorbidity and health-threatening risk factors in subjects with mental disorders, and the risks of mental disorders in those with physical diseases for the last 12 months in the general Korean population.

METHODS

Korean Epidemiologic Catchment Area study replication (KECA-R) was conducted for 6,510 adults between August 2006 and April 2007. The Korean version of Composite International Diagnostic Interview 2.1 (K-CIDI) was used in the survey. Prevalence of mental and physical disorders, and risk factors for physical health were calculated, and their associations were evaluated with adjustment for age and sex.

RESULTS

Subjects with any mental disorder showed significantly higher prevalence of chronic physical conditions (adjusted odds ratio, AOR=1.5 to 2.8, p<0.001) and medical risk factors including smoking, heavy drinking, overweight, and hypertension (AOR=1.5 to 4.0, p<0.001). Of those with chronic physical conditions, 21.6% had one or more comorbid mental disorder compared with 10.5% of the subjects without chronic physical disorders (AOR=2.6, p<0.001). Contrary to expectations, depressive disorders did not show significant association with hypertension and prevalence of obesity was not influenced by presence of mental disorders. Further studies should assess these findings.

CONCLUSION

This is the first identification of significant mental-physical comorbidity in the general Korean population. Clinicians and health care officials should keep in mind of its potential adverse effects on treatment outcome and aggravated disease-related socioeconomic burden.

Associations of specific phobia and its subtypes with physical diseases: an adult community study

BACKGROUND

Specific phobia is the most prevalent anxiety disorder in the community and is associated with substantial impairment. Comorbidity with physical diseases is assumed and has important implications for etiology, treatment, or prevention of the comorbid conditions. However, due to methodological issues data are limited and subtypes of specific phobia have not been investigated yet. We examined the association of specific phobia and its subtypes with physical diseases in a representative community sample with physician-diagnosed physical diseases and diagnostic criteria of specific phobia.

METHODS

Data of the German Mental Health Survey from 4181 subjects aged 18-65 years were used. Specific phobia was diagnosed using M-CIDI/DIA-X interview; physical diseases were assessed through a self-report questionnaire and a medical interview. Logistic regression analyses adjusted for sex were calculated.

RESULTS

Specific phobia was associated with cardiac diseases, gastrointestinal diseases, respiratory diseases, arthritic conditions, migraine, and thyroid diseases (odds ratios between 1.49 and 2.53). Among the subtypes, different patterns of associations with physical diseases were established. The findings were partially replicated in the Swiss PsyCoLaus Study.

CONCLUSIONS

Our analyses show that subjects with specific phobia have an increased probability for specific physical diseases. From these analyses etiological mechanisms of specific phobia and physical disease can be deduced. As subtypes differed in their patterns of associations with physical diseases, different etiological mechanisms may play a role. The findings are highly relevant for public health in terms of prevention and therapy of the comorbid conditions.

Coexisting anxiety disorders alter associations with physical disorders in the elderly: A Taiwan cross-sectional nationwide study

AIM

We used population-based analyses to explore whether anxiety disorders are associated with certain physical illnesses, as previous studies have suggested, and whether a greater number of comorbid anxiety disorders would influence physical illnesses in the elderly.

METHODS

Using the National Health Insurance Research Database, we included subjects aged over 60 years. The study included 954 subjects with anxiety disorders (as defined by the ICD-9-CM) and 4770 control subjects without anxiety disorders. Odds ratios (OR) were calculated for the risks of physical illnesses in both groups.

RESULTS

Subjects with anxiety disorders had higher OR for cardiovascular disease (OR = 1.33-2.80), cerebrovascular disease (OR = 2.07), peptic ulcer (OR = 3.41), and hyperlipidemia (OR = 2.99). Furthermore, a greater number of comorbid anxiety disorders may further increase the OR of the aforementioned physical illnesses, except for peripheral vascular disorder, when compared to those without anxiety disorders.

CONCLUSION

Elderly subjects with more anxiety disorders may be associated with vascular and metabolic problems. Clinicians should carefully assess the physical illnesses of elderly patients with anxiety disorders.

Comorbidities Among Persons With Incident Psychiatric Condition

OBJECTIVE

I sought to determine how medical comorbidities co-exist with incident psychiatric condition.

METHOD

I used data from all 11 available waves (1992-2012) of the Health and Retirement Study (HRS). I identified 4,358 index participants with self-reported incident psychiatric condition. I collected comorbidity data from participants preceding, including, and succeeding that incident wave. Comorbidities assessed included high blood pressure (HBP), diabetes mellitus, cancer, lung disease, heart disease, stroke, and arthritis. Modified Poisson regression combined with log-linked binomial regression was used to estimate relative risks (RRs) of reporting a comorbidity preceding and following the incident wave. Multiple comparison testing dictated significance of RRs with p < .007.

RESULTS

For the waves preceding the index wave, the RRs of reporting all comorbidities except HBP and cancer were significantly (p < .007) increased. For the waves following incident psychiatric condition, the risks of reporting heart disease, diabetes, and lung disease were significantly (p < .007) increased. These results were adjusted for participant age, race, gender, other comorbidities listed, and the wave in which a comorbidity was reported.

CONCLUSION

The bidirectional association between a psychiatric condition and medical illnesses could only be statistically confirmed for lung disease, diabetes, and heart disease. It is of interest to determine how reporting a psychiatric condition may affect the sequelae of health care use and treatment outcomes for patients with either of these comorbidities or a combination of them.

Associations between DSM-IV mental disorders and subsequent onset of arthritis

OBJECTIVE

We investigated the associations between DSM-IV mental disorders and subsequent arthritis onset, with and without mental disorder comorbidity adjustment. We aimed to determine whether specific types of mental disorders and increasing numbers of mental disorders were associated with the onset of arthritis later in life.

METHOD

Data were collected using face-to-face household surveys, conducted in 19 countries from different regions of the world (n=52,095). Lifetime prevalence and age at onset of 16 DSM-IV mental disorders were assessed retrospectively with the World Health Organization (WHO) Composite International Diagnostic Interview (WHO-CIDI). Arthritis was assessed by self-report of lifetime history of arthritis and age at onset. Survival analyses estimated the association of initial onset of mental disorders with subsequent onset of arthritis.

RESULTS

After adjusting for comorbidity, the number of mood, anxiety, impulse-control, and substance disorders remained significantly associated with arthritis onset showing odds ratios (ORs) ranging from 1.2 to 1.4. Additionally, the risk of developing arthritis increased as the number of mental disorders increased from one to five or more disorders.

CONCLUSION

This study suggests links between mental disorders and subsequent arthritis onset using a large, multi-country dataset. These associations lend support to the idea that it may be possible to reduce the severity of mental disorder-arthritis comorbidity through early identification and effective treatment of mental disorders.

Clinical significance of worry and physical symptoms in late-life generalized anxiety disorder

OBJECTIVE

Worry is a hallmark feature of generalized anxiety disorder (GAD). However, age-related changes in symptom presentation raise questions about the clinical significance of these symptom clusters in later life. The aim of this study was to explore the relative contribution of worry and physical symptom frequency to clinical significance associated with late-life GAD.

METHODS

A sample of 637 self-reported worriers (aged 65 years and older) was extracted from Wave 1 of the National Epidemiological Survey of Alcohol and Related Conditions.

RESULTS

Consistent with previous findings, we observed reductions in worry frequency and increases in physical symptom frequency with increasing age of participants. Physical symptoms, but not worry symptoms, distinguished older adults with clinical and sub-threshold GAD. Whereas physical symptom count was associated with distress, occupational, and functional disability, worry count was only associated with distress.

CONCLUSIONS

Among self-reported worriers, worry frequency provides limited clinical utility over and above physical symptom frequency. These findings suggest that physical symptom frequency may become an increasingly important feature of GAD in later life.

The National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) Waves 1 and 2: review and summary of findings

PURPOSE

The NESARC, a "third-generation" psychiatric epidemiologic survey that integrated detailed measures of alcohol and drug use and problems has been the data source for over >850 publications. A comprehensive review of NESARC findings and their implications is lacking.

METHOD

NESARC was a survey of 43,093 participants that covered alcohol, drug and psychiatric disorders, risk factors, and consequences. Wave 1 of the NESARC was conducted in 2001-2002. Three years later, Wave 2 follow-up re-interviews were conducted with 34,653 of the original participants. Scopus and Pubmed were used to search for NESARC papers, which were sorted into topic areas and summarized.

RESULT

The most common disorders were alcohol and posttraumatic stress disorders, and major depression. Females had more internalizing disorders and males had more externalizing disorders, although the preponderance of males with alcohol disorders (the "gender gap") was less pronounced than it was in previous decades. A race/ethnic "paradox" (lower risk among disadvantaged minorities than whites) remains unexplained. Younger participants had higher risk for substance and personality disorders, but not unipolar depressive or anxiety disorders. Psychiatric comorbidity was extensive and often formed latent trans-diagnostic domains. Since 1991-1992, risk for marijuana and prescription drug disorders increased, while smoking decreased, although smoking decreases were less pronounced among those with comorbidity. A nexus of comorbidity, social support, and stress predicted transitions in diagnostic status between Waves 1 and 2. Childhood maltreatment predicted psychopathology. Alcohol and drug use disorders were seldom treated; attitudinal barriers (little perceived need, perceived alcoholism stigma, pessimism about efficacy) were more important in predicting non-treatment than financial barriers.

CONCLUSIONS

Understanding comorbidity and the effects of early stressors will require research incorporating biologic components, e.g., genetic variants and brain imaging. The lack of treatment for alcohol and drug disorders, predicted by attitudinal rather than financial variables, suggests an urgent need for public and professional education to reduce the stigma associated with these disorders and increase knowledge of treatment options.
