ABSTRACT There has been limited characterization of the burden of anxiety and depression, especially the former, among US adults with arthritis in the general population. The study objective was to estimate the prevalence and correlates of anxiety and depression among US adults with doctor-diagnosed arthritis.
The study sample comprised US adults ages ≥ 45 years with doctor-diagnosed arthritis (n = 1,793) from the Arthritis Conditions Health Effects Survey (a cross-sectional, population-based, random-digit-dialed telephone interview survey). Anxiety and depression were measured using separate and validated subscales of the Arthritis Impact Measurement Scales. Prevalence was estimated for the sample overall and stratified by subgroups. Associations between correlates and each condition were estimated with prevalence ratios and 95% confidence intervals using logistic regression models.
Anxiety was more common than depression (31% and 18%, respectively); overall, one-third of respondents reported at least 1 of the 2 conditions. Most (84%) of those with depression also had anxiety. Multivariable logistic regression modeling failed to identify a distinct profile of characteristics of those with anxiety and/or depression. Only half of the respondents with anxiety and/or depression had sought help for their mental health condition in the past year.
Despite the clinical focus on depression among people with arthritis, anxiety was almost twice as common as depression. Given their high prevalence, their profound impact on quality of life, and the range of effective treatments available, we encourage health care providers to screen all people with arthritis for both anxiety and depression.

    ABSTRACT: Many instruments exist to assess mental disorders and anxiety, such as the hospital anxiety and depression scale (HADS). Nothing has been evaluated on the HADS factor structure for use with orthopedic trauma patients. The aim of this study was to validate the underlying structure of the HADS. Specifically, we sought to understand which of the factor structures found in the literature is appropriate for the orthopedic trauma patient population. This study included 348 patients with an average age of 49.8 years (SD: 18.4; range: 18 - 95). Confirmatory data analysis was performed to analyze the latent structure of the HADS. Akaike information criterion (AIC) was used to compare all the models, with the lowest AIC being the best fitting model. We found that both the anxiety and the depression factors were highly correlated (with Pearson correlations greater than 0.700). After removing one item from each subscale, we found that a two-factor model was the best fitting one (AIC: 8,298.901); all other models had an AIC over 10,000. Our results support a satisfactory two-factor structure for the HADS in the orthopedic trauma patients. Further studies are needed to test for higher factor structures in larger samples and in a different population.

    ABSTRACT: 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.

    ABSTRACT: Rheumatoid arthritis (RA) is a costly and crippling autoimmune disease that can lead to the development of depression, contributing to suboptimal clinical outcomes. However, no longitudinal studies have identified an association between rheumatoid arthritis and subsequent depression. This study aimed to investigate the incidence and risk factors of depression among RA patients in Taiwan. Using Taiwan's National Health Insurance Research Database, we identified 3,698 newly diagnosed RA patients aged 18 years or older, together with 7,396 subjects without RA matched by sex, age and index date, between 2000 and 2004. The incidence of depression and the risk factors among RA cases were evaluated using Cox proportional-hazard regression. The incidence of depression was 1.74-fold greater in the RA cohort than in the non-RA cohort (11.80 versus 6.89 per 1,000 person-years; p<0.01). Multivariate analysis showed that RA subjects who were female, were older, or had comorbidities such as stroke, chronic kidney disease, or cancer had a significantly greater risk of depression compared with those without these conditions. This population-based cohort study showed a strong relationship between RA and a subsequent risk of depression. The findings could be beneficial to healthcare providers for identifying individuals with a higher predisposition for depression, thereby possibly facilitating the provision of an appropriate rehabilitation intervention after RA onset to support the patient's adaptation.
