The Association of Cigarette Smoking With Depression and Anxiety: A Systematic Review

Nanoassemblies from the aqueous extract of roasted coffee beans modulate the behavioral and molecular effects of smoking withdrawal-induced anxiety in female rats

Antioxidant-rich plant extracts have demonstrated tremendous value as inflammatory modulators and as nanomaterial precursors. Chronic cigarette smoking alters neurotransmitter systems, particularly the glutamatergic system, and produces neuroinflammation. This study aimed to investigate the behavioral and molecular correlates of cigarette smoking withdrawal-induced anxiety-like behavior in rats, and whether these effects could be mitigated by the administration of antioxidant nanoassemblies prepared by spontaneous oxidation of dark-roasted Arabica coffee bean aqueous extracts. Four experimental groups of female Sprague-Dawley rats were randomly assigned to: (i) a control group that was only exposed to room air, (ii) a COF group that was administered 20 mg/kg of the coffee nanoassemblies by oral gavage, (iii) a SMOK group that was exposed to cigarette smoke and was given an oral gavage of distilled water, (iv) and a SMOK + COF group that was exposed to cigarette smoke and administered 20 mg/kg of the coffee nanoassemblies. Animals were exposed to cigarette smoke for 2 h per day, five days per week, with a 2-day withdrawal period each week. At the end of the 4th week, rats began receiving either distilled water or the coffee nanoassemblies before being exposed to cigarette smoke for 21 additional days. Weekly behavioral tests revealed that cigarette smoking withdrawal exacerbated anxiety, while the administration of the coffee nanoassemblies reduced this effect. The effect of cigarette smoking on astroglial glutamate transporters and nuclear factor kappa B (NF-κB) expression in brain subregions was also measured. Smoking reduced the relative mRNA and protein levels of the glutamate transporter 1 (GLT-1) and the cystine/glutamate antiporter (xCT), and increased the levels of NF-κB, but these effects were attenuated by the coffee nanoassemblies. Thus, administration of the antioxidant nanoassemblies decreased the negative effects of cigarette smoke, which included neuroinflammation, changes in glutamate transporters' expression, and a rise in anxiety-like behavior.

The absence of association between anorexia nervosa and smoking: converging evidence across two studies

Previous studies have found increased smoking prevalence amongst adults with anorexia nervosa (AN) compared to the general population. The current investigation explored bidirectional associations between AN and smoking behaviour (initiation and heaviness), to address questions surrounding causation. In Study One, logistic regression models with variance robust standard errors assessed longitudinal associations between AN and smoking, using data from adolescent participants of the Avon Longitudinal Study of Parents and Children (N = 5100). In Study Two, two-sample Mendelian randomisation (MR) tested possible causal effects using summary statistics from publicly available genome-wide association studies (GWAS). Study One provided no clear evidence for a predictive effect of AN on subsequent smoking behaviour, or for smoking heaviness/initiation predicting later AN. MR findings did not support causal effects between AN and smoking behaviour, in either direction. Findings do not support predictive or causal effects between AN and smoking behaviour. Previously reported associations may have been vulnerable to confounding, highlighting the possibility of smoking and AN sharing causal risk factors.

Associations of lifestyle with mental health and well-being in Chinese adults: a nationwide study

Background

A healthy lifestyle is beneficial to individuals' health. However, little is known about the associations of lifestyle factors with mental health and well-being. This study examined the associations of lifestyle factors with mental health (i.e., depression, anxiety, loneliness, perceived pressure, and self-rated health status) and well-being in Chinese adults.

Methods

A nationally representative survey was conducted in China from 20 June 2022 to 31 August 2022. Data from the survey were analyzed using multiple linear regression to determine the associations of lifestyle with mental health and well-being in Chinese adults. Standardized regression coefficients (β) and 95% confidence intervals (CIs) were estimated using multiple linear regression.

Results

The survey included 28,138 Chinese adults. Multiple linear regression results showed that there were significant negative associations of lifestyle scores with scores of depression (β = -0.93, 95% CI: -0.98, -0.88), anxiety (β = -0.71, 95% CI: -0.76, -0.67), loneliness (β = -0.23, 95% CI: -0.24, -0.21), and perceived pressure (β = -0.19, 95% CI: -0.22, -0.16). Moreover, there were significant positive associations of lifestyle with self-rated health status (β = 1.99, 95% CI: 1.79, 2.20) and well-being (β = 0.96, 95% CI: 0.91, 1.02).

Conclusion

This study provides insight into the associations of lifestyle factors with mental health and well-being and highlights the importance of improving and maintaining healthy lifestyle behaviors for favorable mental health and well-being.

COVID-19 pandemic: Evaluating its psychological impact and individuals' depression, anxiety, and stress levels

Background

The COVID-19 pandemic is a global public health problem affecting mental health, and basic data are required for evidence-based mental health interventions. This study aimed to identify the prevalence of psychological impacts, anxiety, depression, stress, and any associated risk factors in individuals living in Turkey during the COVID-19 pandemic.

Materials and methods

The population of this descriptive study consisted of individuals over the age of 18 living in Turkey. The data were collected between July-September 2020 using the snowball sampling method. The study was completed with 1733 participants. The data were collected using the Impact of Events Scale-Revised and the Depression Anxiety Stress Scale. Statistical analyses included percentage, mean, standard deviation, a Chi-square test, a Mann Whitney U test, Kruskal Wallis and Tamhane's T2 post hoc, and Spearman's correlation. P < 0.05 was considered statistically significant.

Results

45.1% had moderate or severe psychological effects; 42.7% had a moderate or severe depression, 31.7% had moderate or severe anxiety, and 28.5% had moderate or severe stress levels. Being a woman, being single, unemployment, smoking, the presence of chronic diseases, being young (<35), being a university graduate, having a household size of 5 or more, a low income, having poor health, and being underweight were significantly correlated with some psychological impact, depression, anxiety, and stress levels of people.

Conclusion

During the pandemic period, almost half of the respondents were found to experience some psychological impact of the pandemic and have negative moderate to severe mental health levels. Risk groups for mental health were identified.

Clinical guidelines for the use of lifestyle-based mental health care in major depressive disorder: World Federation of Societies for Biological Psychiatry (WFSBP) and Australasian Society of Lifestyle Medicine (ASLM) taskforce

OBJECTIVES

The primary objectives of these international guidelines were to provide a global audience of clinicians with (a) a series of evidence-based recommendations for the provision of lifestyle-based mental health care in clinical practice for adults with Major Depressive Disorder (MDD) and (b) a series of implementation considerations that may be applicable across a range of settings.

METHODS

Recommendations and associated evidence-based gradings were based on a series of systematic literature searches of published research as well as the clinical expertise of taskforce members. The focus of the guidelines was eight lifestyle domains: physical activity and exercise, smoking cessation, work-directed interventions, mindfulness-based and stress management therapies, diet, sleep, loneliness and social support, and green space interaction. The following electronic bibliographic databases were searched for articles published prior to June 2020: PubMed, EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register), CINAHL, PsycINFO. Evidence grading was based on the level of evidence specific to MDD and risk of bias, in accordance with the World Federation of Societies for Biological Psychiatry criteria.

RESULTS

Nine recommendations were formed. The recommendations with the highest ratings to improve MDD were the use of physical activity and exercise, relaxation techniques, work-directed interventions, sleep, and mindfulness-based therapies (Grade 2). Interventions related to diet and green space were recommended, but with a lower strength of evidence (Grade 3). Recommendations regarding smoking cessation and loneliness and social support were based on expert opinion. Key implementation considerations included the need for input from allied health professionals and support networks to implement this type of approach, the importance of partnering such recommendations with behaviour change support, and the need to deliver interventions using a biopsychosocial-cultural framework.

CONCLUSIONS

Lifestyle-based interventions are recommended as a foundational component of mental health care in clinical practice for adults with Major Depressive Disorder, where other evidence-based therapies can be added or used in combination. The findings and recommendations of these guidelines support the need for further research to address existing gaps in efficacy and implementation research, especially for emerging lifestyle-based approaches (e.g. green space, loneliness and social support interventions) where data are limited. Further work is also needed to develop innovative approaches for delivery and models of care, and to support the training of health professionals regarding lifestyle-based mental health care.

Longitudinal transitions in e-cigarette and cigarette use among US adults: prospective cohort study

Background

To support tobacco control efforts, this study sought to characterize longitudinal transitions in use of electronic nicotine delivery systems (ENDS) and cigarettes.

Methods

Participants were nationally representative samples of 53,729 US adults from Waves 3-5 (2015-2019) of the Population Assessment of Tobacco and Health Study. We examined behavioral transitions (initiation, relapse, progression, and cessation) in ENDS and cigarette use across waves. Weighted generalized estimating equation models adjusted for sociodemographic variables.

Findings

Of never ENDS users at baseline, an estimated 1.7% reported initiating ENDS use by follow-up. Of former ENDS users, an estimated 12.1% relapsed into ENDS use. Of periodic ENDS users at baseline, 13% progressed to established ENDS use. Of baseline current ENDS users, 46.3% discontinued ENDS use. The corresponding transitions for cigarette smoking were 1.6% (initiation), 4.8% (relapse), 21.1% (progression), and 14% (discontinuation). Adults aged 18-24 (vs. older age), Hispanics (vs. non-Hispanic white), and past 12-month cannabis users were more likely to initiate ENDS or cigarettes (all p < 0.05). Having any internalizing mental health symptoms increased the odds of ENDS initiation, while externalizing symptoms increased the odds of cigarette initiation. Those who perceived nicotine as very harmful (vs. none/low harm) were more likely to discontinue ENDS. Current cigarette users (vs. non-users) at baseline were more likely to initiate, relapse, or discontinue ENDS (all p < 0.05) and vice versa.

Interpretation

We observed high changeability in ENDS and cigarette use among US adults over time. In absolute terms, ENDS use grew, while smoking fell. Tobacco control programs should focus on priority populations, including young adults and people with internalizing and externalizing mental health symptoms.

Psychosocial predictors of trajectories of dual cigarette and e-cigarette use among young adults in the US

INTRODUCTION

Young adults have the highest prevalence of cigarette and e-cigarette use, warranting research to identify psychosocial correlates of their use trajectories.

METHODS

Repeated measures latent profile analyses (RMLPAs) examined past 6-month cigarette and e-cigarette trajectories across 5 waves of data (2018-2020) among 3,006 young adults (Mage = 24.56 [SD = 4.72], 54.8% female, 31.6% sexual minority, 60.2% racial/ethnic minority). Multinomial logistic regression models examined associations among psychosocial factors (i.e., depressive symptoms, adverse childhood experiences [ACEs], personality traits) and trajectories of cigarette and e-cigarette use, controlling for sociodemographics and past 6-month alcohol and cannabis use.

RESULTS

RMLPAs yielded a 6-profile solution, which were uniquely associated with predictors: stable low-level or nonusers of cigarettes and e-cigarettes (66.3%; referent group), stable low-level cigarette and high-level e-cigarette use (12.3%; greater depressive symptoms, ACEs, openness; male, White, cannabis use), stable mid-level cigarette and low-level e-cigarette use (6.2%; greater depressive symptoms, ACEs, extraversion; less openness, conscientiousness; older age, male, Black or Hispanic, cannabis use), stable low-level cigarette and decreasing e-cigarette use (6.0%; greater depressive symptoms, ACEs, openness; younger age, cannabis use), stable high-level cigarette and low-level e-cigarette use (4.7%; greater depressive symptoms, ACEs, extraversion; older age, cannabis use), and decreasing high-level cigarette and stable high-level e-cigarette use (4.5%; greater depressive symptoms, ACEs, extraversion, less conscientiousness; older age, cannabis use).

CONCLUSIONS

Cigarette and e-cigarette prevention and cessation efforts should be targeted both toward specific trajectories of use and their unique psychosocial correlates.

Depressive symptoms and vaping: The mediating effect of outcome expectancies among young adults

OBJECTIVE

The purpose of the present study was to determine if positive affect reinforcement and social enhancement outcome expectancies mediate the longitudinal association between depressive symptoms and frequency of electronic nicotine delivery systems (ENDS) use one year later among young adults.

METHOD

Participants were 1567 young adults participating in the first three waves of the Marketing and Promotions Across Colleges in Texas project. At Wave 1 participants were 18-25 years old (M = 20.27; SD = 1.86), 61.46% female; 36.25% non-Hispanic white, 33.95% Hispanic/Latino, 14.10% Asian, 7.72% African American/Black, 7.98% two or more races/ethnicities or another race/ethnicity. The independent variable, depressive symptoms, was assessed with the CES-D-10 at Wave 1. The mediating variables, positive affect reinforcement and social enhancement ENDS outcome expectancies were assessed using items adapted from the Youth Tobacco Survey at Wave 2 six months later. The outcome variable was frequency of past 30-day ENDS use at Wave 3, one year after Wave 1. A mediation model was used to test the study hypothesis.

RESULTS

Positive affect reinforcement ENDS outcome expectancies (b = 0.013, SE = 0.006, Bootstrap 95%CI: [0.003, 0.025]), but not social enhancement expectancies (b = -0.004, SE = 0.003, Bootstrap 95%CI: [-0.010, 0.0003]), mediated the positive association between elevated depressive symptoms and frequency of ENDS use one year later.

CONCLUSION

Results indicate young adults experiencing elevated depressive symptoms may use ENDS at a greater frequency than their peers because they believe ENDS use will alleviate stress, increase relaxation and/or concentration.

The Role of Perceived Neighborhood Cohesion in the Association between Depressive Symptoms and Cigarette Smoking

BACKGROUND

Greater depression has been linked to increased smoking rates. However, the mechanisms underlying this association are not fully understood. It is possible that high perceived neighborhood cohesion may serve as one such mechanism given its associations with decreased depression and smoking. Having increased levels of depression likely impacts one's perceptions of neighborhood cohesion, which could lead to further increases in depression and a need to manage these symptoms via cigarette smoking. As a first test of this theory, the current study examined the effect of neighborhood cohesion on the association between depressive symptoms and smoking frequency and quantity among past 30-day cigarette smokers.

METHODS

Participants were 201 combustible cigarette smokers (Mage = 48.33, SD = 11.64; 63.2% female; 68.2% White) who completed self-report measures as part of a larger study of environmental influences on cardiac health.

RESULTS

Greater depressive symptoms were associated with lower levels of perceived neighborhood cohesion, and there was a significant indirect effect of greater depressive symptoms on heavier smoking through decreased neighborhood cohesion (b = .07, SE = .04, 95% CI [.003, .15]). There was no significant indirect effect for daily smoking.

CONCLUSION

These results suggest that neighborhood cohesion is an important contextual factor that serves as one explanatory mechanism for the well-established relationship between depression and smoking quantity. Thus, there may be utility in implementing interventions focused on increasing neighborhood cohesion as a way to decrease smoking behavior.

Depression in Heart Failure with Reduced Ejection Fraction, an Undervalued Comorbidity: An Up-To-Date Review

Introduction: Depression is a common and severe comorbidity among individuals with heart failure (HF). Up to a third of all HF patients are depressed, and an even higher proportion have symptoms of depression. Aim: In this review, we evaluate the relationship between HF and depression, explain the pathophysiology and epidemiology of both diseases and their relationship, and highlight novel diagnostic and therapeutic options for HF patients with depression. Materials and Methods: This narrative review involved keyword searches of PubMed and Web of Science. Review search terms included ["Depression" OR "Depres*" OR "major depr*"] AND ["Heart Failure" OR "HF" OR "HFrEF" OR "HFmrEF" OR "HFpEF" OR "HFimpEF"] in all fields. Studies included in the review met the following criteria: (A) published in a peer-reviewed journal; (B) described the impact of depression on HF and vice versa; and (C) were opinion papers, guidelines, case studies, descriptive studies, randomized control trials, prospective studies, retrospective studies, narrative reviews, and systematic reviews. Results: Depression is an emergent HF risk factor and strongly relates with worse clinical outcomes. HF and depression share multiple pathways, including platelet dis-reactivity, neuroendocrine malfunction, inappropriate inflammation, tachi-arrhythmias, and frailty in the social and community setting. Existing HF guidelines urge evaluation of depression in all HF patients, and numerous screening tools are available. Depression is ultimately diagnosed based on DSM-5 criteria. There are both non-pharmaceutical and pharmaceutical treatments for depression. Regarding depressed symptoms, non-pharmaceutical treatments, such as cognitive-behavioral therapy and physical exercise, have shown therapeutic results, under medical supervision and with an effort level adapted to the patient's physical resources, together with optimal HF treatment. In randomized clinical studies, selective serotonin reuptake inhibitors, the backbone of antidepressant treatment, did not demonstrate advantage over the placebo in patients with HF. New antidepressant medications are currently being studied and could provide a chance to enhance management, treatment, and control of depression in patients with HF. Conclusions: Despite the substantial link between depression and HF, their combination is underdiagnosed and undertreated. Considering the hopeful yet unclear findings of antidepressant trials, further research is required to identify people who may benefit from antidepressant medication. The goal of future research should be a complete approach to the care of these patients, who are anticipated to become a significant medical burden in the future.

Sleep Paralysis and Lucid Dreaming-Between Waking and Dreaming: A Review about Two Extraordinary States

BACKGROUND

Sleep paralysis and lucid dreams are two states of consciousness that are connected to REM sleep but are defined by higher awareness in contrast to regular REM sleep. Despite these similarities, the two states differ widely in their emotional tone and their perceived controllability. This review aims to summarize the current research containing sleep paralysis and lucid dreams. However, given the sparsity of the research, one single topic cannot be chosen.

METHODS

Articles containing both lucid dreams as well as sleep paralysis were searched for in the following databanks: MEDLINE, Scopus, Web of Science, PsycInfo, PsycArticles, and PSYNDEX. Further, citations of the found papers were examined.

RESULTS

10 studies were included in the review. Most of the studies were surveys, but there was also a case study, a randomized trial, and an observational EEG study. The numbers of participants ranged from a single participant in the case study to 1928 participants in a survey. The main findings were that correlations between sleep paralysis and lucid dreaming were positive and significant in most of the studies.

CONCLUSIONS

There is a connection between lucid dreaming and sleep paralysis. However, research is still very limited and diverse in the methodologies used. Future research should build standardized methods for examining the two phenomena.

Evaluation of nutritional status and clinical depression classification using an explainable machine learning method

Introduction

Depression is a prevalent disorder worldwide, with potentially severe implications. It contributes significantly to an increased risk of diseases associated with multiple risk factors. Early accurate diagnosis of depressive symptoms is a critical first step toward management, intervention, and prevention. Various nutritional and dietary compounds have been suggested to be involved in the onset, maintenance, and severity of depressive disorders. Despite the challenges to better understanding the association between nutritional risk factors and the occurrence of depression, assessing the interplay of these markers through supervised machine learning remains to be fully explored.

Methods

This study aimed to determine the ability of machine learning-based decision support methods to identify the presence of depression using publicly available health data from the Korean National Health and Nutrition Examination Survey. Two exploration techniques, namely, uniform manifold approximation and projection and Pearson correlation, were performed for explanatory analysis among datasets. A grid search optimization with cross-validation was performed to fine-tune the models for classifying depression with the highest accuracy. Several performance measures, including accuracy, precision, recall, F1 score, confusion matrix, areas under the precision-recall and receiver operating characteristic curves, and calibration plot, were used to compare classifier performances. We further investigated the importance of the features provided: visualized interpretation using ELI5, partial dependence plots, and local interpretable using model-agnostic explanations and Shapley additive explanation for the prediction at both the population and individual levels.

Results

The best model achieved an accuracy of 86.18% for XGBoost and an area under the curve of 84.96% for the random forest model in original dataset and the XGBoost algorithm with an accuracy of 86.02% and an area under the curve of 85.34% in the quantile-based dataset. The explainable results revealed a complementary observation of the relative changes in feature values, and, thus, the importance of emergent depression risks could be identified.

Discussion

The strength of our approach is the large sample size used for training with a fine-tuned model. The machine learning-based analysis showed that the hyper-tuned model has empirically higher accuracy in classifying patients with depressive disorder, as evidenced by the set of interpretable experiments, and can be an effective solution for disease control.

Factors associated with new-onset depressive symptoms in patients starting cardiac rehabilitation: Pre-COVID-19 and COVID-19 period comparison

OBJECTIVE

We aim to: 1) investigate whether starting cardiac rehabilitation (CR) during the COVID-19 period was influential on new-onset depressive symptoms, 2) examine the relationship between sociodemographic and medical factors with the new-onset of depressive symptoms before and during the COVID-19 period in UK patients commencing CR.

METHODS

The national audit of cardiac rehabilitation (NACR) data were used and the two years of data before COVID-19 and during COVID-19 were analysed (Feb,2018 - Nov,2021). Hospital Anxiety and Depression Scale measurement was used to assess depressive symptoms. Bivariate analysis and logistic regression were conducted to examine the influence of the COVID-19 period on new-onset depressive symptoms and the patient characteristics associated with it.

RESULTS

71055 patients screened for new-onset depressive symptoms were included in the analysis. Based on multivariate analysis, patients commencing CR during COVID-19 were 8% more likely to have new onset depressive symptoms compared to patients commencing before COVID-19. Smoking (OR: 1.26, 95%CI: 1.11, 1.43), physical inactivity (OR: 1.86, 95%CI: 1.74, 1.98), high anxiety (OR: 1.45, 95%CI: 1.44, 1.46), being male (OR: 1.21, 95%CI: 1.12, 1.30), single (OR: 1.25, 95%CI: 1.16, 1.35), having comorbidities of arthritis, diabetes, chronic bronchitis, emphysema, claudication (OR range: 1.19 to 1.60), receiving CABG treatment (OR: 1.47, 95%CI: 1.25, 1.73), and having heart failure (OR: 1.33, 95%CI: 1.19, 1.48) were the factors associated with having new-onset depressive symptoms at the start of CR.

CONCLUSION

Our findings have shown that starting CR during the COVID-19 period was associated with increased odds of having new-onset depressive symptoms.

Comparison of the Smoking Cessation of Heated Tobacco Product Users and Conventional Cigarette Smokers in Korea

BACKGROUND

Since the introduction of heated tobacco products (HTPs) in Korea in 2017, their annual sales have increased. Several studies have investigated the perceptions of HTPs and smoking cessation behaviors. For the first time, In 2019, questions focused on HTP use were introduced in the Korea National Health and Nutrition Examination Survey (KNHNES). This study aimed to compare smoking cessation behaviors between HTP users and conventional cigarette smokers using KNHANES data.

METHODS

Data of 947 current adult smokers from the 8th KNHNES (2019) were analyzed. Current smokers were divided into conventional cigarette (CC)-only, HTP-only, and dual-use groups. The general characteristics of the three groups were investigated. Differences in current intention to quit smoking and past attempts to quit smoking among the three groups were analyzed using multivariate logistic regression analysis by IBM SPSS ver. 25.0.

RESULTS

HTP-only users demonstrated fewer future smoking cessation plans (adjusted odds ratio [AOR], 0.398; 95% confidence interval [CI], 0.195-0.813; P=0.012) and fewer smoking cessation attempts in the past year (AOR, 0.533; 95% CI, 0.298-0.954; P=0.034) than CC-only smokers. However, there was no significant difference between dual-use (CC+HTP) and CC-only smokers.

CONCLUSION

While dual-use and CC-only smokers showed similar smoking cessation behaviors, HTP-only users had fewer previous attempts to quit smoking and were less likely to be currently ready to quit smoking. These findings can be explained by a decrease in the need to quit smoking due to the convenience of HTP and the perception that HTPs are less harmful than CC.

Evaluation of a Possible Association Between Severity of Allergic Rhinitis and the Level of Depression in Patients in a Tertiary Care Hospital in South India: A Cross-Sectional Study

Introduction Allergic rhinitis is one of the most common diseases in the world. It affects all people irrespective of age, sex and race. Allergic rhinitis leads to the development of social and interpersonal problems and loss of productivity which in turn causes depression. The depression was an underestimated iceberg phenomenon in allergic rhinitis patients. Objective The study evaluates the association between the severity of allergic rhinitis and the level of depression in patients attending tertiary care hospitals in south India. Methodology This cross-sectional study was conducted among 250 patients with allergic rhinitis. All the patients were subjected to the semi-structured questionnaire. And the severity of allergic rhinitis has been made based on the allergic rhinitis, and its impact on asthma classification and depression has been diagnosed and classified based on the Hamilton depression rating scale. And the association between allergic rhinitis and depression has been evaluated with the chi-square test. Results Two hundred fifty patients participated in the study, with a mean age of 33+/-2. Surprisingly the prevalence of depression among the allergic rhinitis patient was 88%. Most of them suffered from mild depression based on the Hamilton depression rating scale. A significant association was seen among allergic patients with age, gender, smoking status, locality, socioeconomic status, and co-morbidities. And the study shows the severity of allergic rhinitis is directly related to the severity of depression with a significant association. Conclusion Depression is one of the underestimated and under-treated problems in today's world. This study concludes that the severity of allergic rhinitis directly and significantly correlates with the severity of depression. The prevalence and intensity of depression should be evaluated and appropriately treated in patients with allergic rhinitis to improve the quality of life.

Prevalence of depressive symptoms and cannabis use among adult cigarette smokers in Canada: cross-sectional findings from the 2020 International Tobacco Control Policy Evaluation Project Canada Smoking and Vaping Survey

BACKGROUND

Tobacco smoking and cannabis use are independently associated with depression, and evidence suggests that people who use both tobacco and cannabis (co-consumers) are more likely to report mental health problems, greater nicotine dependence and alcohol misuse than those who use either product exclusively. We examined prevalence of cannabis use and depressive symptoms among Canadian adults who smoke cigarettes and tested whether co-consumers of cannabis and tobacco were more likely to report depressive symptoms than cigarette-only smokers; we also tested whether cigarette-only smokers and co-consumers differed on cigarette dependence measures, motivation to quit smoking and risky alcohol use by the presence or absence of depressive symptoms.

METHODS

We analyzed cross-sectional data from adult (age ≥ 18 yr) current (≥ monthly) cigarette smokers from the Canadian arm of the 2020 International Tobacco Control Policy Evaluation Project Four Country Smoking and Vaping Survey. Canadian respondents were recruited from Leger's online probability panel across all 10 provinces. We estimated weighted percentages for depressive symptoms and cannabis use among all respondents and tested whether co-consumers (≥ monthly use of cannabis and cigarettes) were more likely to report depressive symptoms than cigarette-only smokers. Weighted multivariable regression models were used to identify differences between co-consumers and cigarette-only smokers with and without depressive symptoms.

RESULTS

A total of 2843 current smokers were included in the study. The prevalence of past-year, past-30-day and daily cannabis use was 44.0%, 33.2% and 16.1%, respectively (30.4% reported using cannabis at least monthly). Among all respondents, 30.0% screened positive for depressive symptoms, with co-consumers being more likely to report depressive symptoms (36.5%) than those who did not report current cannabis use (27.4%, p < 0.001). Depressive symptoms were associated with planning to quit smoking (p = 0.01), having made multiple attempts to quit smoking (p < 0.001), the perception of being very addicted to cigarettes (p < 0.001) and strong urges to smoke (p = 0.001), whereas cannabis use was not (all p ≥ 0.05). Cannabis use was associated with high-risk alcohol consumption (p < 0.001), whereas depressive symptoms were not (p = 0.1).

INTERPRETATION

Co-consumers were more likely to report depressive symptoms and high-risk alcohol consumption; however, only depression, and not cannabis use, was associated with greater motivation to quit smoking and greater perceived dependence on cigarettes. A deeper understanding of how cannabis, alcohol use and depression interact among people who smoke cigarettes is needed, as well as how these factors affect cessation activity over time.

Age and Sex Differences in the Association between Serum Vitamin E Levels and Depressive Symptoms: Korea National Health and Nutrition Examination Survey

Studies have reported inconsistent results regarding the relationship between serum vitamin E levels and depressive symptoms. Furthermore, the potential modulating role of age and sex has been underexplored. We conduct an age- and sex-stratified investigation of the association between serological vitamin E status and depressive symptoms in a large nationwide sample. Data from the Korean National Health and Nutrition Examination Survey were analyzed (n = 4448). The participants were stratified into four groups according to age (<65 vs. ≥65 years) and sex. Each group was divided into tertiles of vitamin E/total lipid ratio, and Patient Health Questionnaire-9 (PHQ-9) scores were compared among the tertiles via multivariable linear regression analyses. The relationship between dietary supplement use and the proportions of tertiles was assessed in each group. With the middle tertile as the reference group, the low tertile of vitamin E/total lipid ratio was associated with increased PHQ-9 scores in younger females and older males after adjusting for all covariates, while the high tertile showed no significant associations with PHQ-9 scores in any group. The low tertile was associated with increased adjusted mean PHQ-9 scores by 0.53 and 1.02 compared to the middle tertile in younger females and older males, respectively. Dietary supplement use was related to higher vitamin E/total lipid ratio in all four groups. In conclusion, younger females and older males with a low vitamin E status showed worse depressive symptoms. These individuals may benefit from dietary interventions to prevent depressive symptoms.

Sleep Apnea and Substance Use Disorders Associated with Co-Occurrence of Anxiety Disorder and Depression among U.S. Adults: Findings from the NSDUH 2008-2014

Few studies have focused on sleep apnea and substance use disorders with co-occurrence of anxiety disorder and depression. This study included a total of 270,227 adults, 9268 with co-occurrence of anxiety disorder and depression in the past year, from the combined 2008-2014 National Survey on Drug Use and Health (NSDUH) data, which are the latest datasets with measures of anxiety disorder and sleep apnea. Weighted multinomial logistic regression analyses were used to estimate the associations between anxiety disorder and depression and their co-occurrence. Comorbidity was highly prevalent: 40.4% of those with depression also met the criteria for anxiety disorder, whereas 51.8% of those with anxiety disorder also met the criteria for depression. The prevalences of anxiety only and co-occurrence increased from 2008 to 2014. The prevalences of anxiety disorder only, depression only, and co-occurrence of anxiety disorder and depression in individuals with sleep apnea were 4.4%, 12.9%, and 12.2%, respectively, and the prevalences in substance use disorders were 6.4%, 9.4%, and 10.7%, respectively. The results showed that sleep apnea, substance use disorders, and nicotine dependence were significantly associated with increased odds of anxiety disorder, depression, and co-occurrence (all p values < 0.0001). Furthermore, several chronic diseases (asthma, bronchitis, hypertension, and heart disease) were associated with the co-occurrence of anxiety disorder and depression. These findings suggest clinicians and other healthcare providers consider screening for depression and anxiety with sleep apnea and substance use disorders for improved therapeutic outcomes.

The Tet2–Upf1 complex modulates mRNA stability under stress conditions

Introduction: Environmental stress promotes epigenetic alterations that impact gene expression and subsequently participate in the pathological processes of the disorder. Among epigenetic regulations, ten–eleven Translocation (Tet) enzymes oxidize 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) in DNA and RNA and function as critical players in the pathogenesis of diseases. Our previous results showed that chronic stress increases the expression of cytoplasmic Tet2 in the hippocampus of mice exposed to chronic mild stress (CMS). Whether the cytoplasmic Tet2 alters RNA 5hmC modification in chronic stress-related processes remains largely unknown.

Methods: To explore the role of cytoplasmic Tet2 under CMS conditions, we established CMS mice model and detected the expression of RNA 5hmC by dot blot. We verified the interaction of Tet2 and its interacting protein by co-immunoprecipitation combined with mass spectrometry and screened downstream target genes by cluster analysis of Tet2 and upstream frameshift 1 (Upf1) interacting RNA. The expression of protein was detected by Western blot and the expression of the screened target genes was detected by qRT-PCR.

Results: In this study, we found that increased cytoplasmic Tet2 expression under CMS conditions leads to increase in total RNA 5hmC modification. Tet2 interacted with the key non-sense-mediated mRNA decay (NMD) factor Upf1, regulated the stability of stress-related genes such as Unc5b mRNA, and might thereby affect neurodevelopment.

Discussion: In summary, this study revealed that Tet2-mediated RNA 5hmC modification is involved in stress-related mRNA stability regulation and may serve as a potential therapeutic target for chronic stress-related diseases such as depression.

Association Between Comorbid Psychiatric Disorders and Persistent Smoking After a Diagnosis of Chronic Obstructive Pulmonary Disease Among Patients Seeking Treatment at a Tertiary Care Hospital in India

Introduction Smoking cessation is the most effective approach to slowing down the progression of chronic obstructive pulmonary disease (COPD). Despite this, almost half of COPD patients continue to smoke after diagnosis. COPD patients with current smoking status are more likely to have concurrent psychiatric comorbidities, for instance, depression and anxiety. These psychiatric disorders can contribute to the persistence of smoking in individuals with COPD. This study aimed to investigate predictors of smoking persistence in COPD patients. Materials and methods A cross-sectional study was conducted in the Outpatient Department (OPD) of the Department of Pulmonary Medicine in a tertiary care hospital from August 2018 to July 2019. Patients with COPD were screened for their smoking status. All subjects were then personally assessed for any psychiatric comorbidity using the Mini International Neuropsychiatric Interview (MINI), the Patient Health Questionnaire-9 (PHQ-9), and the Anxiety Inventory for Respiratory (AIR) Disease. Logistic regression was performed to compute the odds ratio (OR).  Results The study included a total of 87 COPD patients. Of the 87 COPD patients, 50 were current smokers, and 37 were past smokers. COPD patients with psychiatric disorders were four times more likely to continue smoking than those without psychiatric comorbidities (OR: 4.62, 95% CI: 1.46-14.54). The results showed that increasing PHQ-9 scores by one unit in COPD patients increased the likelihood of continuing to smoke by 27 percent. Conclusion In our multivariate analysis, current depression was found as a significant predictor of continued smoking in COPD patients. The present results are consistent with reports from previous research that depressive symptoms are associated with continued smoking in patients with COPD. COPD patients who are currently smoking should be examined for psychiatric disorders and treated concurrently to achieve effective smoking cessation.

TFOS lifestyle: Impact of societal challenges on the ocular surface

Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.

Pathophysiology of nAChRs: limbic circuits and related disorders

Human epidemiological studies have identified links between nicotine intake and stress disorders, including anxiety, depression and PTSD. Here we review the clinical evidence for activation and desensitization of nicotinic acetylcholine receptors (nAChRs) relevant to affective disorders. We go on to describe clinical and preclinical pharmacological studies suggesting that nAChR function may be involved in the etiology of anxiety and depressive disorders, may be relevant targets for medication development, and may contribute to the antidepressant efficacy of non-nicotinic therapeutics. We then review what is known about nAChR function in a subset of limbic system areas (amygdala, hippocampus and prefrontal cortex), and how this contributes to stress-relevant behaviors in preclinical models that may be relevant to human affective disorders. Taken together, the preclinical and clinical literature point to a clear role for ACh signaling through nAChRs in regulation of behavioral responses to stress. Disruption of nAChR homeostasis is likely to contribute to the psychopathology observed in anxiety and depressive disorders. Targeting specific nAChRs may therefore be a strategy for medication development to treat these disorders or to augment the efficacy of current therapeutics.

Feeling Not Wanted/Loved and Depression: Does Gender Matter?

Depression affects over 17 million American adults yearly and has been identified as the leading cause of disability in people between the ages of 15 and 44 years. There is evidence that feeling neglect or a lack of parental attachment during childhood is associated with depression. One construct that has been overlooked is love from a parent. The purpose of this study was to analyze the association between individuals who felt not wanted/loved during adolescence and lifetime depression and to examine this association by gender. We examined 5114 participants aged 24-32 years at Wave IV of the National Longitudinal Study of Adolescent Health (Add Health) public use dataset. We used logistic regression analysis to determine the association between an individual feeling not wanted/loved by their parent/caregiver prior to age 18, covariates, and lifetime depression. We then stratified by gender and ran logistic models for both men and women separately. Overall, 16.2% (n = 827) reported lifetime depression diagnosis, while 16.5% of the participants reported feeling not wanted/loved "often," while 29.8% reported it as "sometimes." Feeling not wanted/loved "often" was associated with higher odds of depression (AOR = 3.00; 95% CI, 2.45-3.66; p < .001) versus "sometimes" (AOR = 1.59; 95% CI, 1.31-1.90; p < .001). When stratified by gender, feeling not loved/wanted was associated with depression among both men (AOR = 3.70; 95% CI, 2.60-5.25; p < .001) and women (AOR = 2.73; 95% CI, 2.13-3.48; p < .001). Feeling not loved or wanted by a parent/caregiver during adolescence has serious implications, for both men and women. Future studies should further examine this construct and identify family-based interventions that focus on parent/caregiver and child relationships.

Estimated prevalence and trends in smoking among adolescents in South Korea, 2005-2021: a nationwide serial study

BACKGROUND

Although smoking is classified as a risk factor for severe COVID-19 outcomes, there is a scarcity of studies on prevalence of smoking during the COVID-19 pandemic. Thus, this study aims to analyze the trends of prevalence of smoking in adolescents over the COVID-19 pandemic period.

METHODS

The present study used data from middle to high school adolescents between 2005 and 2021 who participated in the Korea Youth Risk Behavior Web-based Survey (KYRBS). We evaluated the smoking prevalence (ever or daily) by year groups and estimated the slope in smoking prevalence before and during the pandemic.

RESULTS

A total of 1,137,823 adolescents participated in the study [mean age, 15.04 years [95% confidence interval (CI) 15.03-15.06]; and male, 52.4% (95% CI 51.7-53.1)]. The prevalence of ever smokers was 27.7% (95% CI 27.3-28.1) between 2005 and 2008 but decreased to 9.8% (95% CI 9.3-10.3) in 2021. A consistent trend was found in daily smokers, as the estimates decreased from 5.4% (95% CI 5.2-5.6) between 2005 and 2008 to 2.3% (95% CI 2.1-2.5) in 2021. However, the downward slope in the overall prevalence of ever smokers and daily smokers became less pronounced in the COVID-19 pandemic period than in the pre-pandemic period. In the subgroup with substance use, the decreasing slope in daily smokers was significantly more pronounced during the pandemic than during the pre-pandemic period.

CONCLUSIONS

The proportion of ever smokers and daily smokers showed a less pronounced decreasing trend during the pandemic. The findings of our study provide an overall understanding of the pandemic's impact on smoking prevalence in adolescents. Supplementary file2 (MP4 64897 KB).

Influência de Fatores Psicológicos e Sociais nos Comportamentos Preventivos de Saúde dos Homens

Introdução: Homens tendem a retardar a procura por serviços de saúde e têm baixa adesão a tratamentos, causando piores indicadores de saúde. Objetivou-se analisar a influência de fatores psicológicos e sociais nos comportamentos preventivos de saúde adotados por homens. Métodos: Utilizaram-se um questionário sociodemográfico, o Inventário de Conformidade com Normas Masculinas (CMNI), o Self-Reporting Questionnaire (SRQ) e o Questionário de Atitudes e Comportamentos de Saúde (QACS). Participaram da análise 315 homens adultos de todo o Brasil. Resultados: Uma regressão linear revelou que eram preditores de menor prevenção: pontuar alto em traços que indicavam desejo por admiração e respeito e comportamentos sexuais arriscados, bem como a maior probabilidade de presença de transtorno mental, ter cor de pele preta e menor nível educacional. Discussão: Foram mapeados fatores de risco para a menor conduta preventiva em homens. Conclusão: Conclui-se que variáveis psicológicas e sociais exercem forte influência sobre os comportamentos de saúde dos homens, sendo necessárias ações de promoção da saúde masculina para além das políticas públicas existentes, na busca pela elaboração de novas ações focadas neste grupo e temática específicos.

Boredom Susceptibility and Quit Smoking: The Role of Anxiety Symptoms

Boredom is one of the main reported motives for smoking. However, scarce research has examined the relationship between boredom susceptibility and abstinence achievement in treatment-seeking smokers. The aim of this study is to examine the mediating effect of anxiety symptoms in the relationship between boredom susceptibility and abstinence at the end of a smoking cessation treatment. The sample was composed of 481 Spanish smokers who received a cognitive-behavioral treatment to quit (M_age= 45.51, SD = 11.16; 60.6% female). The Boredom Susceptibility subscale of the Sensation Seeking Scale Form-V and the Beck Anxiety Inventory were used. Pearson correlations and mediation analyses were conducted to examine the relationships between the study variables. Boredom susceptibility was significantly and positively correlated to anxiety symptoms, but not to abstinence. Anxiety symptoms were significantly and negatively correlated to abstinence. A significant indirect effect of boredom susceptibility on abstinence at the end of treatment through anxiety symptoms was found. There was no direct relation between boredom susceptibility and abstinence. These findings extend previous literature by showing that higher boredom susceptibility is associated with less likelihood to be abstinent at the end of the treatment through higher anxiety symptoms. These results highlight the relevance of considering the inclusion of boredom and anxiety management techniques in smoking cessation interventions.

Predictors of success/failure in the control of asthmatic smoking patients under conditions of clinical practice

BACKGROUND

Tobacco smoking directly affects the airway, where it triggers a very strong local inflammatory response.

OBJECTIVE

To determine the predictors of improvement or worsening of asthma control in asthmatic smokers.

METHODS

Observational, prospective, multicenter, single cohort study, carried out in the outpatient pulmonology departments with a follow-up period of 6 months. The treatment was adjusted according to the indications of standard clinical practice.

RESULTS

196 patients were included, with a mean age of 54.64 years.39% of the patients were active smokers. Interpreting an Asthma Control Questionnaire (ACQ) score of ≤ 0.75 as asthma control, this was achieved in 30.2% of the cases. Patients with greater adherence were more likely to improve their asthma symptoms (p < 0.05), defined as a decrease in ACQ of 0.5 points or more at the final visit, while taking concomitant medication was a negative risk factor for improvement (p < 0.001). An eosinophil value >300 was a predictor for achieving control (p < 0.01). Patients treated with fluticasone propionate/formoterol versus those receiving budesonide/formoterol or beclomethasone/formoterol had a lower ACQ score (p < 0.01 and p < 0.01, respectively).

CONCLUSION

Asthmatic patients with active tobacco exposure and a higher number of anti-asthma medications are more likely to have poorer control. Correct adherence to treatment is the main intervention to be performed to achieve the control. An eosinophil count greater than 300 was the main predictor for achieving control. Fluticasone propionate/formoterol FP/FORM was associated with a greater likelihood of improving ACQ score.

Associations of dual use of tobacco cigarettes and e-cigarettes, sleep duration, physical activity and depressive symptoms among middle-aged and older Korean adults

AIM

There is limited evidence of the association between dual tobacco-e-cigarette use and health-related variables in Korea. Thus, this study aimed to investigate the associations between types of cigarette smoking, sleep duration, physical activity and depressive symptoms among Korean adults.

DESIGN

A cross-sectional study design using the 2019 Korean Community Health Survey.

METHODS

The study subjects consisted of 179,004 adults older than 40 years from a total of 229,099 individuals. Self-reported general characteristics, smoking history, sleep duration, physical activity and depressive symptoms were analysed.

RESULTS

In multinomial logistic regression, dual users of tobacco cigarettes and e-cigarettes were more likely to have sleep duration of less than 7 h per day and to report both mild and moderate-to-severe depressive symptoms than non-smokers. Single use of either cigarettes or e-cigarettes increased the risk of short sleep duration and moderate-to-severe depressive symptoms.

Sex difference in the associations among risk factors with depression in a large Taiwanese population study

Background

Depression is a common psychiatric health issue affecting an estimated 5% of adults worldwide, and it can lead to disability and increased economic burden. Consequently, identifying the factors associated with depression as early as possible is a vital issue. The aim of this study was to explore these associations in a large cohort of 121,601 Taiwanese participants in the Taiwan Biobank, and also to identify sex differences in the associations.

Methods

The study cohort included 77,902 women and 43,699 men (mean age, 49.9 ± 11.0 years), who were further classified into those with depression (n = 4,362; 3.6%) and those without depression (n = 117,239; 96.4%).

Results

The results of multivariable analysis showed that female sex (vs. male sex; odds ratio = 2.578; 95% confidence interval = 2.319–2.866; p &lt; 0.001) was significantly associated with depression. Older age, diabetes mellitus (DM), hypertension, low systolic blood pressure (SBP), smoking history, living alone, low glycated hemoglobin (HbA1c), high triglycerides, and low uric acid were significantly associated with depression in the men. In the women, older age, DM, hypertension, low SBP, smoking history, alcohol history, education level of middle and high school (vs. lower than elementary school), living alone, high body mass index (BMI), menopause, low HbA1c, high triglycerides, high total cholesterol, low estimated glomerular filtration rate (eGFR), and low uric acid were significantly associated with depression. Further, there were significant interactions between sex and DM (p = 0.047), smoking history (p &lt; 0.001), alcohol use (p &lt; 0.001), BMI (p = 0.022), triglyceride (p = 0.033), eGFR (p = 0.001), and uric acid (p = 0.004) on depression.

Conclusion

In conclusion, our results showed sex differences in depression, and the women were significantly associated with depression compared to men. Furthermore, we also found sex differences among the risk factors associated with depression.

Cigarette and e-cigarette use as a function of psychological distress following COVID-19 related university campus closures

Background: Individuals experienced increased social isolation resulting from the COVID-19 pandemic. Studies have found social isolation and loneliness to be strongly associated with anxiety and depression, which have been associated with increased smoking and vaping rates among young adults, including college students.Objectives: To examine relationships between psychological distress and nicotine use within the context of the COVID-19 pandemic.Methods: A cross-sectional online survey (n = 4634; 77.9% female) was used to collect nicotine use and psychological measures from students enrolled at a large Midwestern university. Timeline follow-back data were collected from students reporting current cigarette or electronic cigarette (e-cigarette) use in the week before and immediately following the closure of campus due to the pandemic. Generalized estimating equations were used to examine the interaction between nicotine use and psychological symptoms across the 2-week period.Results: Both cigarette (Rate ratio (RR) = 1.115, 95% CI = 1.061, 1.171, p < .0001) and e-cigarette (β = 0.258, 95% CI = 0.166, 0.351, p < .0001) use increased significantly following campus closure. Students experiencing higher levels of depression reported greater increases in e-cigarette use frequency over time as compared to students reporting fewer symptoms of depression (β = 0.018, 95% CI = 0.006, 0.030, p = .004).Conclusions: Increases in nicotine use were found immediately following the implementation of public health safety measures that closed most university campuses. Additional and/or increased stressors have potentially impacted young adults who are college students as a result of campus closures resulting from the pandemic, which may have contributed to further increases in nicotine use.

An Unusual College Experience: 16-Month Trajectories of Depressive Symptoms and Anxiety among Chinese New Undergraduate Students of 2019 during the COVID-19 Pandemic

BACKGROUND

This study examines the trajectories of the mental health conditions of 13,494 new undergraduate students who enrolled in 2019 in China from the beginning of the pandemic to the local recurrence of the pandemic, and found factors which may be associated with diverse trajectories.

METHODS

The trajectories of depression-anxiety outcomes were modeled using the growth mixture model. The multinomial logistic regression model was used to identify variables associated with different trajectory groups.

RESULTS

Both depression and anxiety in the new college students slightly increased during the 16-month period. The slopes of depression and anxiety were lower after the local outbreak. From the trajectories of depression and anxiety, five heterogeneous groups were identified: low-stable (64.3%), moderate-increased (18.2%), high-stable (11.1%), recovery (4.5%), and rapid-increased (1.8%). Environmental, somatic, and social factors were used to differentiate the low-stable group from the other groups. We found that college students with female gender, more conflict with parents, and feelings of loneliness during the pandemic were more likely to enter a high stability trajectory compared to a recovery trajectory.

CONCLUSION

Most participants showed a stable mental health status, while others experienced deteriorating or chronic mental health problems, especially those who had sleep disturbances, less social support before the pandemic, or conflicts with parents during the pandemic. These students may need additional support and monitoring from college mental health providers to improve their wellbeing.

Prospective Bidirectional Relations Between Depression and Metabolic Health: 30 Year Follow-up from the NHLBI CARDIA Study

Objective

This study investigated prospective bidirectional relationships between depression and metabolic syndrome (MetS), and the moderating effects of race, sex, and health behaviors in a diverse cohort followed for 30 years.

Methods

Data were analyzed from the NHLBI CARDIA study, a 30 year-prospective study of young adults (N = 5113; M age = 24.76 (SD = 3.63) at baseline; 45% male) who were tested every 5 years between 1985-2015. Measures included biological assessments of MetS components, and self-reported depressive symptoms based on the Center for Epidemiologic Studies Depression (CESD) scale. Data analyses included bi-directional general estimating equations analyses of time-lagged associations between depressive symptoms and MetS.

Results

There was a consistent, bi-directional relationship between depressive symptoms and MetS over time. Individuals with more CESD depressive symptoms were more likely to develop MetS over time compared to those reporting fewer symptoms (Wald Chi-Square = 7.09 (1), p < 0.008), and MetS was similarly predictive of CESD. MetS more consistently predicted depressive symptoms at each 5-year exam than depressive symptoms predicted MetS. Race and sex moderated relationships between depression and MetS, with White females, White individuals overall, and females overall demonstrating significant relationships. Health behaviors were not related to depression-MetS associations.

Conclusion

In a diverse young adult population prospectively followed into late middle age, MetS more consistently predicted depression over time than depression predicted MetS. The relation between MetS and depressive symptoms was moderated by race and sex, but not health behaviors.

Predictors of Discontinued E-Cigarette Use at One-Year Follow-Up in a Sample of Young Adults

BACKGROUND

Currently, the research on factors associated with young adults' discontinuation of e-cigarette use behavior is limited. This study tested the predictors of self-reported e-cigarette abstinence at one-year follow-up among young adult baseline current e-cigarette users. The following variables were tested as predictors: demographics, cigarette smoking, e-cigarette use dependence, e-cigarette use duration, harm perceptions, and preferred aspects of e-cigarette use, including sensations, flavor, and device characteristics.

METHODS

Data were provided at two time-points one year apart by 435 ethnically diverse young adults (M age = 22.3, SD = 3.1; 63% women) who reported current e-cigarette use at baseline.

RESULTS

Approximately 42% of those who reported current e-cigarette use at baseline (i.e., 184 out of 435 participants) reported discontinuation of e-cigarette use at one-year follow-up. Results indicated that higher e-cigarette dependence, longer history of e-cigarette use, lower e-cigarette harm perceptions, greater preference for both menthol and sweet flavors, for open-pod-based devices, and for e-cigarette use sensations such as buzz, taste and smell of flavors, and throat hit at baseline were associated with lower likelihood of e-cigarette use discontinuation at one-year follow-up.

CONCLUSIONS

Characteristics associated with nicotine (e.g., dependence) and flavors (e.g., taste and smell) appear to drive the continuation/discontinuation of e-cigarette use among young adults. Thus, cessation strategies may need to be developed with a focus on dependence and harm perceptions related to nicotine and flavors. Furthermore, better regulating open-pod-based devices and sweet-menthol flavors may help e-cigarette use prevention.

Age-dependent effects of tobacco smoke and nicotine on cognition and the brain: A systematic review of the human and animal literature comparing adolescents and adults

Cigarette smoking is often initiated during adolescence and an earlier age of onset is associated with worse health outcomes later in life. Paradoxically, the transition towards adulthood also marks the potential for recovery, as the majority of adolescents are able to quit smoking when adulthood emerges. This systematic review aimed to evaluate the evidence from both human and animal studies for the differential impact of adolescent versus adult repeated and long-term tobacco and nicotine exposure on cognitive and brain outcomes. The limited human studies and more extensive yet heterogeneous animal studies, provide preliminary evidence of heightened fear learning, anxiety-related behaviour, reward processing, nicotinic acetylcholinergic receptors expression, dopamine expression and serotonin functioning after adolescent compared to adult exposure. Effects of nicotine or tobacco use on impulsivity were comparable across age groups. These findings provide novel insights into the mechanisms underlying adolescents' vulnerability to tobacco and nicotine. Future research is needed to translate animal to human findings, with a focus on directly linking a broader spectrum of brain and behavioural outcomes.

Tobacco use modify exon IV BDNF gene methylation levels in depression

This study aimed to investigate BDNF gene methylation in individuals with depression based on tobacco use. Therefore, 384 adults from southeastern Brazil were recruited to assess depression, socioeconomic status, lifestyle, and methylation by pyrosequencing exon IV promoter region of the BDNF gene. The Generalized Linear Model (GzLM) was used to check the effect of depression, tobacco, and the interaction between depression and tobacco use in methylation levels. In addition, the Kruskal-Wallis test, followed by Dunn's post hoc test, was used to compare methylation levels. Interaction between depression and tobacco use was significant at levels of BDNF methylation in the CpG 5 (p = 0.045), 8 (p = 0.016), 9 (p = 0.042), 10 (p = 0.026) and mean 5-11 (p < 0.001). Dunn's post hoc test showed that individuals with depression and tobacco use compared to those with or without depression who did not use tobacco had lower levels of BDNF methylation in CpG 5, 6, 7, 8, 9, 11, and mean 5-11. Therefore, we suggest that tobacco use appears to interfere with BDNF gene methylation in depressed individuals.

Exercise as a therapeutic modality for the prevention and treatment of depression

While maintaining an active lifestyle and engaging in regular exercise are known to promote cardiovascular (CV) health, increasing evidence has emerged to indicate that these lifestyle behaviors also can promote psychological health and well-being. This has led to research to determine if exercise can serve as a potential therapeutic modality for major depressive disorder (MDD), which is a leading cause of mental-health impairment and overall disability worldwide. The strongest evidence to support this use comes from an increasing number of randomized clinical trials (RCTs) that have compared exercise to usual care, placebo controls, or established therapies in healthy adults and in various clinical populations. The relatively large number of RCTs has led to numerous reviews and meta-analyses, which generally have been concordant in indicating that exercise ameliorates depressive symptoms, improves self-esteem, and enhances various aspects of quality of life. Together, these data indicate that exercise should be considered as a therapeutic modality for improving CV health and psychological well-being. The emerging evidence also has led to a new proposed subspecialty of "lifestyle psychiatry", which promotes the use of exercise as an adjunctive treatment for patients with MDD. Indeed, some medical organizations have now endorsed lifestyle-based approaches as foundational aspects of depression management, with adoption of exercise as a treatment option for MDD. This review summarizes research in the area and provides practical suggestions for the use of exercise in clinical practice.

Prevalence of tobacco smoking in people at clinical high-risk for psychosis: Systematic review and meta-analysis

Several hypotheses have been proposed to explain why individuals with psychosis consume more tobacco compared with the general population, but the reasons remain unclear. The phases predating the onset of psychosis could provide an interesting framework to clarify this association. The aim of this systematic review and meta-analysis is to provide an updated and comprehensive synthesis of the association between tobacco smoking and Clinical High Risk for Psychosis (CHRP) status. We performed a multistep systematic PRISMA/MOOSE-compliant electronic search for articles published from inception until October 1st, 2021. Web of Science was searched, complemented by a manual search of original articles reporting the outcome of tobacco consumption (defined as the number of individuals which were smoking tobacco at baseline) in a group of CHR-P patients versus healthy controls (HC). We employed quality assessment of the included studies with Newcastle Ottawa Scale (NOS). The effect size for the primary outcome was the odds ratio (OR) of smoking tobacco in CHR-P samples vs HC. We performed a random-effects model meta-analysis, assessment of heterogeneity with I² index, sensitivity analyses excluding one study at a time for primary outcome, meta-regressions with four independent moderators (mean age, female ratio, sample size, NOS) and assessment of publication bias with funnel plot and Egger's test. We included 21 independent articles, totalling 2018 CHR-P individuals (mean age of 21.35 ± 2.91 years and average female ratio of 41 ± 7 %) and 1160 HC (mean age of 22.42 ± 3.70 years and average female ratio of 45 ± 11 %). The NOS score was 6.52 ± 1.25 (range from 0 to 9). The OR of smoking status was 2.22 (95%CI 1.74-2.84, p < 0.01). Heterogeneity (I²) was 24.09 (p = 0.16). Sensitivity analyses, removing one study at a time, revealed the robustness of our main finding. Meta-regressions did not reveal any significant association between the moderators and the main outcome. Visual inspection of the funnel plot and Egger's test did not reveal evident publication bias. Our main finding of an increased OR of smokers in the CHR-P individuals compared to healthy controls corroborates the accumulation of unhealthy lifestyles in this vulnerable group. This does not demonstrate any causal association between tobacco smoking and incidence of psychosis, which should be investigated in future prospective cohorts. In conclusion, the window of opportunity represented by CHR-P status should involve more efficient physical health screening and better investigating the aetiological impact of smoking in the development of psychosis.

Short-term improvement of mental health after a COVID-19 vaccination

INTRODUCTION

The role of COVID-19 vaccination on the mental health of the general population remains poorly understood. This study aims to assess the short-term change in depressive and anxiety symptoms in relation to COVID-19 vaccination among Swedish adults.

METHODS

A prospective study of 7,925 individuals recruited from ongoing cohort studies at the Karolinska Institutet, Stockholm, Sweden, or through social media campaigns, with monthly data collections on self-reported depressive and anxiety symptoms from December 2020 to October 2021 and COVID-19 vaccination from July to October 2021. Prevalence of depressive and anxiety symptoms (defined as a self-reported total score of ≥10 in PHQ-9 and GAD-7, respectively) was calculated one month before, one month after the first dose, and, if applicable, one month after the second dose. For individuals not vaccinated or choosing not to report vaccination status (unvaccinated individuals), we selected three monthly measures of PHQ-9 and GAD-7 with 2-month intervals in-between based on data availability.

RESULTS

5,079 (64.1%) individuals received two doses of COVID-19 vaccine, 1,977 (24.9%) received one dose, 305 (3.9%) were not vaccinated, and 564 (7.1%) chose not to report vaccination status. There was a lower prevalence of depressive and anxiety symptoms among vaccinated, compared to unvaccinated individuals, especially after the second dose. Among individuals receiving two doses of vaccine, the prevalence of depressive and anxiety symptoms was lower after both first (aRR = 0.82, 95%CI 0.76-0.88 for depression; aRR = 0.81, 95%CI 0.73-0.89 for anxiety) and second (aRR = 0.79, 95%CI 0.73-0.85 for depression; aRR = 0.73, 95%CI 0.66-0.81 for anxiety) dose, compared to before vaccination. Similar results were observed among individuals receiving only one dose (aRR = 0.76, 95%CI 0.68-0.84 for depression; aRR = 0.82, 95%CI 0.72-0.94 for anxiety), comparing after first dose to before vaccination.

CONCLUSIONS

We observed a short-term improvement in depressive and anxiety symptoms among adults receiving COVID-19 vaccines in the current pandemic. Our findings provide new evidence to support outreach campaigns targeting hesitant groups.

Latinx Individuals Who Smoke Daily with and without a Probable Anxiety Disorder: Differences in Smoking Behavior and Beliefs about Abstinence

There is a well-established relation between anxiety psychopathology and smoking in the general population. However, little work focuses on Latinx/Hispanic (hereafter Latinx) persons who smoke from this comorbidity perspective. The present investigation aimed to explore differences among English-speaking Latinx adults who live in the United States (US) and smoke cigarettes with and without a probable anxiety disorder in terms of cigarette dependence, perceived barriers for quitting, severity of problems when quitting, and smoking abstinence expectancies. The sample included 338 adult Latinx daily cigarette smokers (Mage = 35.53 years; SD = 8.65; age range 18-61; 37.3% female) who identified as Latinx and were recruited nationally throughout the US. Results indicated that among Latinx persons who smoke, those with a probable anxiety disorder (compared to those without) were more likely to demonstrate higher levels of cigarette dependence, severity of problems when trying to quit, perceived barriers for quitting, and negative abstinence expectancies after adjusting for key variables linked to smoking and anxiety (e.g., hazardous drinking, education). The current findings are the first to document probable anxiety disorder status as a clinically relevant factor for a wide range of smoking variables and beliefs about abstinence among Latinx persons who smoke.

Association of Depression and Poor Mental Health With Cardiovascular Disease and Suboptimal Cardiovascular Health Among Young Adults in the United States

Background Depression is a nontraditional risk factor for cardiovascular disease (CVD). Data on the association of depression and poor mental health with CVD and suboptimal cardiovascular health (CVH) among young adults are limited. Methods and Results We used data from 593 616 young adults (aged 18-49 years) from the 2017 to 2020 Behavioral Risk Factor Surveillance System, a nationally representative survey of noninstitutionalized US adults. Exposures were self-reported depression and poor mental health days (PMHDs; categorized as 0, 1-13, and 14-30 days of poor mental health in the past 30 days). Outcomes were self-reported CVD (composite of myocardial infarction, angina, or stroke) and suboptimal CVH (≥2 cardiovascular risk factors: hypertension, hypercholesterolemia, overweight/obesity, smoking, diabetes, physical inactivity, and inadequate fruit and vegetable intake). Using logistic regression, we investigated the association of depression and PMHDs with CVD and suboptimal CVH, adjusting for sociodemographic factors (and cardiovascular risk factors for the CVD outcome). Of the 593 616 participants (mean age, 34.7±9.0 years), the weighted prevalence of depression was 19.6% (95% CI, 19.4-19.8), and the weighted prevalence of CVD was 2.5% (95% CI, 2.4-2.6). People with depression had higher odds of CVD than those without depression (odds ratio [OR], 2.32 [95% CI, 2.13-2.51]). There was a graded association of PMHDs with CVD. Compared with individuals with 0 PMHDs, the odds of CVD in those with 1 to 13 PMHDs and 14 to 30 PHMDs were 1.48 (95% CI, 1.34-1.62) and 2.29 (95% CI, 2.08-2.51), respectively, after adjusting for sociodemographic and cardiovascular risk factors. The associations did not differ significantly by sex or urban/rural status. Individuals with depression had higher odds of suboptimal CVH (OR, 1.79 [95% CI, 1.65-1.95]) compared with those without depression, with a similar graded relationship between PMHDs and suboptimal CVH. Conclusions Depression and poor mental health are associated with premature CVD and suboptimal CVH among young adults. Although this association is likely bidirectional, prioritizing mental health may help reduce CVD risk and improve CVH in young adults.

A multiple health behaviour change intervention to prevent depression: A randomized controlled trial

OBJECTIVE

To examine the effectiveness of a 12-month MHBC intervention in the prevention of onset depression in primary health care (PHC).

METHODS

Twenty-two PHC centres took part in the cluster-randomized controlled trial. Patients were randomized to receive either usual care or an MHBC intervention. The endpoints were onset of major depression and reduction of depressive symptoms in participants without baseline depression at a 12-month follow-up.

RESULTS

2531 patients agreed and were eligible to participate. At baseline, around 43% were smokers, 82% were non-adherent to the Mediterranean diet and 55% did not perform enough physical activity. The intervention group exhibited a greater positive change in two or more behaviours (OR 1.75 [95%CI: 1.17 to 2.62]; p = 0.006); any behaviour (OR 1.58 [95%CI: 1.13 to 2.20]; p = 0.007); and adherence to the Mediterranean diet (OR 1.94 [95%CI: 1.29 to 2.94]; p = 0.002), while this increase was not statistically significant for smoking and physical activity. The intervention was not effective in preventing major depression (OR 1.17; [95% CI 0.53 to 2.59)]; p = 0.690) or reducing depressive symptoms (Mean difference: 0.30; [95% CI -0.77 to 1.36]; p = 0.726) during follow-up.

CONCLUSIONS

As compared to usual care, the MHBC intervention provided a non-significant reduction in the incidence of major depression.

[What is the contribution of smoking to the increased risk of suicide in young smokers? A systematic review]

OBJECTIVES

The correlation between smoking and suicide is well documented in the general population: there is an increased risk of suicide among tobacco smokers. However, the association between smoking and suicidal behaviors (ideations, plans, attempts) in youth is poorly elucidated. This is a systematic review of the literature examined data on the relationship between active and passive smoking and suicidal ideation (SI), suicide planning (SP), and suicide attempts (SA) among youth in the general population.

METHOD

Medline searches were performed for the period 1980-2020. Cross-sectional, case-control, prospective population-based studies of young people (age less than 18 years) were included in this review; studies of specific populations (patients with an identified pathology of any kind) were excluded.

RESULTS

This review included 43 studies: 23 studies on the association between active smoking and SI, SI and/or PS, TS; three studies on the association between passive smoking and suicidal behavior, three studies on the association between smoking and suicidal behavior in young people in psychiatric hospital settings, and five studies comparing the suicidal behavior of girls and boys. Analysis of the data collected lead to the conclusion that active or passive smoking is associated with suicidal behavior in young people. Smoking appears to contribute to psychopathological disorders, including depression, the use of other psychoactive substances, or psychosocial suffering which are often associated with an increased risk of suicide in young people. The correlations between smoking and the presence of mental disorders have been highlighted; tobacco use may contribute to the development of depression, anxiety and stress. Further studies are needed to verify the existence of a causal link between smoking and suicide.

CONCLUSION

Smoking is associated with the risk of suicidal behavior in young people; it should be included among the criteria for assessing suicidal risk in youth. Smoking cessation, which improves psychological well-being, should be further integrated into the prevention of suicidal behavior.

The association between tobacco smoking and depression and anxiety in people with multiple sclerosis: A systematic review

BACKGROUND

The link between tobacco smoking and Multiple Sclerosis (MS) onset and progression is well-established. While clinical levels of depression and anxiety are highly prevalent in people living with MS (plwMS), and both are recognized as common MS-related symptoms, the relationships between smoking behavior and depression and anxiety are unclear. This systematic review aimed to synthesize evidence on the relationships between current-smoking and former-smoking and depression and anxiety in plwMS.

METHODS

Systematic review of all studies investigating associations between tobacco smoking and depression and anxiety in plwMS was conducted. Relevant studies published before 26 April 2022 were identified by searching seven databases; MEDLINE® (Ovid and PubMed), Embase, CINAHL®, Cochrane Library and PsycInfo), and citation and reference list checking. Joanna Briggs Institute Critical Appraisal Checklists for respective study designs assessed the risk of bias.

RESULTS

Thirteen publications reporting on 12 studies met study inclusion criteria. Nine of 12 studies examining current-smoking and depression in plwMS identified a positive association. Four prospective studies provided evidence supporting a causal smoking-depression relationship, with 1.3-2.3-fold higher depression prevalence found in current-smokers than non-smokers. Three cross-sectional studies found no smoking-depression association. Four of five included studies found current-smoking was associated with anxiety, with three prospective studies indicating anxiety prevalence was around 20% higher in current-smokers. Former-smoking was associated with increased prevalence of depression, but not anxiety.

CONCLUSION

We provide strong evidence for increased depression prevalence in plwMS who are either current-smokers or former-smokers. However, only current-smoking was associated with increased prevalence of anxiety.

A cross-sectional study of smoking and depression among US adults: NHANES (2005-2018)

Background

The relationship between smoking and depression remains controversial. This study aimed to investigate the association between smoking and depression from three aspects: smoking status, smoking volume, and smoking cessation.

Methods

Data from adults aged ≥20 who participated in the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2018 were collected. The study gathered information about the participants' smoking status (never smokers, previous smokers, occasional smokers, daily smokers), smoking quantity per day, and smoking cessation. Depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9), with a score ≥10 indicating the presence of clinically relevant symptoms. Multivariable logistic regression was conducted to evaluate the association of smoking status, daily smoking volume, and smoking cessation duration with depression.

Results

Previous smokers [odds ratio (OR) = 1.25, 95% confidence interval (CI): 1.05-1.48] and occasional smokers (OR = 1.84, 95% CI: 1.39-2.45) were associated with a higher risk of depression compared with never smokers. Daily smokers had the highest risk of depression (OR = 2.37, 95% CI: 2.05-2.75). In addition, a tendency toward a positive correlation was observed between daily smoking volume and depression (OR = 1.65, 95% CI: 1.24-2.19) (P for trend < 0.05). Furthermore, the longer the smoking cessation duration, the lower the risk of depression (OR = 0.55, 95% CI: 0.39-0.79) (P for trend < 0.05).

Conclusions

Smoking is a behavior that increases the risk of depression. The higher the smoking frequency and smoking volume, the higher the risk of depression, whereas smoking cessation is associated with decreased risk of depression, and the longer the smoking cessation duration, the lower the risk of depression.

Lifestyle management in polycystic ovary syndrome - beyond diet and physical activity

Polycystic ovary syndrome (PCOS) is a common condition affecting reproductive-aged women with reproductive, metabolic and psychological consequences. Weight and lifestyle (diet, physical activity and behavioural) management are first-line therapy in international evidence-based guidelines for PCOS. While these recommend following population-level diet and physical activity guidelines, there is ongoing interest and research in the potential benefit of including psychological and sleep interventions, as well as a range of traditional, complimentary and integrative medicine (TCIM) approaches, for optimal management of PCOS. There is limited evidence to recommend a specific diet composition for PCOS with approaches including modifying protein, carbohydrate or fat quality or quantity generally having similar effects on the presentations of PCOS. With regards to physical activity, promising evidence supports the provision of vigorous aerobic exercise, which has been shown to improve body composition, cardiorespiratory fitness and insulin resistance. Psychological and sleep interventions are also important considerations, with women displaying poor emotional wellbeing and higher rates of clinical and subclinical sleep disturbance, potentially limiting their ability to make positive lifestyle change. While optimising sleep and emotional wellbeing may aid symptom management in PCOS, research exploring the efficacy of clinical interventions is lacking. Uptake of TCIM approaches, in particular supplement and herbal medicine use, by women with PCOS is growing. However, there is currently insufficient evidence to support integration into routine clinical practice. Research investigating inositol supplementation have produced the most promising findings, showing improved metabolic profiles and reduced hyperandrogenism. Findings for other supplements, herbal medicines, acupuncture and yoga is so far inconsistent, and to reduce heterogeneity more research in specific PCOS populations, (e.g. defined age and BMI ranges) and consistent approaches to intervention delivery, duration and comparators are needed. While there are a range of lifestyle components in addition to population-recommendations for diet and physical activity of potential benefit in PCOS, robust clinical trials are warranted to expand the relatively limited evidence-base regarding holistic lifestyle management. With consumer interest in holistic healthcare rising, healthcare providers will be required to broaden their knowledge pertaining to how these therapies can be safely and appropriately utilised as adjuncts to conventional medical management.

Association between Pruritus and Psychosocial Well-being: A Population-based Study among 6,809 Subjects

Pruritus has an extensive impact on functional, social and psychosocial behaviour. The association between pruritus and psychological well-being has mostly been studied among selected patient groups, whereas population-based studies are lacking. The aim of this study was to determine the association between pruritus and insomnia, quality of life, depression and anxiety at the population level in the general population. A cross-sectional population-based study was conducted in 2012 to 2013. Study subjects (n = 6,809) belonging to the Northern Finland Birth Cohort 1966 Study participated in a large follow-up study at the age of 45-47 years. They completed an extensive health questionnaire including questions on pruritus and several previously validated questionnaires regarding symptoms of psychosocial well-being. Pruritus affected 19.9% of the study subjects weekly, being more common in women than in men (p < 0.001). A significant association was found between both localized and generalized pruritus and symptoms of insomnia, depression, anxiety and decreased quality of life. The association was seen even in those with mild psychological symptoms/insomnia, and it affected both sexes. The severity of psychological symptoms increased with increasing frequency of pruritus. In conclusion, pruritus has a multiple effect on psychosocial well-being. Physicians should consider possible psychosocial symptoms in patients with pruritus.

Association Among Chronic Obstructive Pulmonary Disease Severity, Exacerbation Risk, and Anxiety and Depression Symptoms in the SPIROMICS Cohort

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a common, progressive lung disease that often manifests with psychiatric symptoms. Despite this, patients with COPD are not routinely screened for anxiety and depression, which substantially contribute to COPD-related morbidity.

OBJECTIVE

To determine the relationship among COPD symptom severity, exacerbation risk, and clinically significant anxiety and depression symptoms in ever smokers with COPD.

METHODS

We used baseline data from the Subpopulations and Intermediate Outcome Measures In COPD Study (SPIROMICS) cohort to examine ever smokers with COPD across Global Initiative for Obstructive Lung Disease (GOLD) disease severity groups. Multivariable logistic regression models were used to calculate odds ratios for clinically significant anxiety and depression for each GOLD group, which was compared to the control group of ever smokers without COPD. Odds ratios were adjusted for subject demographics, medical comorbidities, and substance use covariates, and comparisons were completed using 2-tailed tests.

RESULTS

Of the 2664 subjects studied, 784 (29.4%) had clinically significant anxiety, and 497 (18.7%) had clinically significant depression. In the multivariable analysis, high pulmonary symptom groups, groups B and D, had increased adjusted odds of clinically significant anxiety (group B: adjusted odds ratios [AOR] 1.28, P = 0.03; group D: AOR 1.95, P < 0.0001) and depression (group B: AOR 2.09, P < 0.0001; group D: AOR 3.04, P < 0.0001). GOLD group D, the group with high pulmonary symptoms and high COPD exacerbation risk, had the greatest risk of both anxiety and depression among the GOLD groups.

CONCLUSIONS

High COPD symptom severity, even in the absence of elevated COPD exacerbation risk, is associated with clinically significant anxiety and depression. Our separate analyses of anxiety and depression symptoms in a large, multisite, national cohort are unique within the literature and have important treatment implications for COPD patients. Our findings also highlight the utility of screening patients with high COPD symptom severity for anxiety and depression.

Evaluating the Association Between Depressive Symptoms and Glycemic Control Among Residents of Rural Appalachia

Introduction

Type 2 diabetes mellitus (T2DM) is associated with a range of co-morbid physical and psychological conditions, including depression. Yet there is a dearth of evidence regarding the prevalence of depression among those in Appalachia living with T2DM; this gap persists despite the higher regional prevalence of T2DM and challenging social determinants of health.

Purpose

This study aimed to provide greater detail about the relationships between T2DM and depressive symptoms in adults living in Appalachia Kentucky.

Methods

The present study was a cross-sectional analysis of baseline data derived from an ongoing study of Appalachia Kentucky adults living with T2DM. Outcome data included demographics, Center for Epidemiologic Studies Depression Scale, point-of-care HbA1c, and the Summary of Diabetes Self-Care Activities. Bivariate analysis was conducted using Pearson's correlation to determine the statistically significant relationships between variables which were then included in a multiple regression model.

Results

The sample (N=365), consisted primarily of women (n=230, 64.6%) of mean age 64 years (±10.6); almost all (98%) were non-Hispanic White (n=349), and most were married (n=208, 59.1%). The majority (47.2%) reported having two comorbid conditions (n=161), including T2DM, and the mean HbA1c was 7.7% (1.7). Nearly 90% were nonsmokers (n=319). Depressive symptoms were reported in 25% (n=90) of participants. A higher number of comorbid conditions, increased age, Medicaid insurance, tobacco use, lower financial status, female sex, and disability compared to fully employed status all were correlated with a higher rate of depressive symptoms (r ≤ 0.2). The regression indicated that depressive symptoms were associated with age (β = -0.010, p = 0.001); full-time employment status compared to those who are disabled (β = -.0209, p = 0.18); men compared to women (β = -0.122, p = 0.042), and those who smoke compared to nonsmokers (β = 0.175, p = 0.038).

Implications

Depressive symptoms were correlated with T2DM among this sample of Appalachian residents with poorly controlled T2DM, especially among women. Given the vast number of social determinants (e.g., poverty, food insecurity, and rurality) affecting this population, healthcare providers must assess for depression and consider its negative influence on the patient's ability to achieve glycemic control.

Associations between depression and anxiety index and frequency of acute exacerbation in chronic obstructive pulmonary disease

BACKGROUND

Comorbidities of chronic obstructive pulmonary disease (COPD) influence clinical characteristics and prognosis.

OBJECTIVES

This study compared the clinical characteristics and exacerbation rate of COPD according to the presence of depression or anxiety.

DESIGN

This study used data from The Korea COPD Subgroup Study (KOCOSS) cohort, a nationwide prospective cohort from 54 medical centers, between April 2012 and 2019.

METHODS

Depression and anxiety were diagnosed with the Beck Depression Inventory and Beck Anxiety Inventory. Negative binomial regression analysis was performed to analyze the frequency of exacerbations in depressed patients and anxiety. Differences in lung function trajectory according to presence of depression/anxiety were analyzed using a linear mixed model.

RESULTS

In all, 2147 patients were enrolled. Depressed patients or anxiety had lower lung function, higher modified Medical Research Council (mMRC) grade, St. George Respiratory Questionnaire (SGRQ) score, and COPD assessment test score, and higher rates of exacerbation in the past year than those without depression/anxiety. Depressed patients had a higher frequency of moderate to severe exacerbations [Incidence Rate Ratio (IRR): 1.57, CI: 1.17-2.11, p = 0.002] and those with anxiety had higher frequencies of moderate to severe (IRR: 1.52, CI: 1.03-2.27, p = 0.038) and severe exacerbations (IRR: 2.13, CI: 1.09-4.15, p = 0.025) during 1-year follow-up compared to those without these comorbidities. The differences in the change in annual forced expiratory volume in 1 seconds (FEV1) over 3 years according to the presence of depression or anxiety were not statistically significant.

CONCLUSION

Depressed and anxious patients showed increased respiratory symptoms and exacerbation rate as well as reduced health-related quality of life, whereas there were no significant differences in changes in lung function between groups with and without depression/anxiety.
