Posttraumatic stress disorder and tobacco use: A systematic review and meta-analysis

Tobacco use, trauma exposure and PTSD: a systematic review

Tobacco use remains one of the most significant preventable public health problems globally and is increasingly concentrated among vulnerable groups, including those with trauma exposure or diagnosed with PTSD. The goal of this systematic review was to update and extend previous reviews. Of the 7224 publications that met the initial criteria, 267 were included in the review. Summary topic areas include conceptual frameworks for the relation between trauma or PTSD and tobacco use; associations between trauma exposure or PTSD and tobacco use; number and type of trauma exposures and tobacco use; PTSD symptoms and tobacco use; Treatment-related studies; and the examination of causal relations. Evidence continues to indicate that individuals exposed to trauma or diagnosed with PTSD are more likely to use tobacco products, more nicotine dependent and less likely to abstain from tobacco even when provided evidence-based treatments than individuals without trauma. The most commonly cited causal association proposed was use of tobacco for self-regulation of negative affect associated with trauma. A small proportion of the studies addressed causality and mechanisms of action. Future work should incorporate methodological approaches and measures from which we can draw causal conclusions and mechanisms to support the development of viable therapeutic targets.

Post-traumatic stress and future substance use outcomes: leveraging antecedent factors to stratify risk

Background

Post-traumatic stress disorder (PTSD) and substance use (tobacco, alcohol, and cannabis) are highly comorbid. Many factors affect this relationship, including sociodemographic and psychosocial characteristics, other prior traumas, and physical health. However, few prior studies have investigated this prospectively, examining new substance use and the extent to which a wide range of factors may modify the relationship to PTSD.

Methods

The Advancing Understanding of RecOvery afteR traumA (AURORA) study is a prospective cohort of adults presenting at emergency departments (N = 2,943). Participants self-reported PTSD symptoms and the frequency and quantity of tobacco, alcohol, and cannabis use at six total timepoints. We assessed the associations of PTSD and future substance use, lagged by one timepoint, using the Poisson generalized estimating equations. We also stratified by incident and prevalent substance use and generated causal forests to identify the most important effect modifiers of this relationship out of 128 potential variables.

Results

At baseline, 37.3% (N = 1,099) of participants reported likely PTSD. PTSD was associated with tobacco frequency (incidence rate ratio (IRR): 1.003, 95% CI: 1.00, 1.01, p = 0.02) and quantity (IRR: 1.01, 95% CI: 1.001, 1.01, p = 0.01), and alcohol frequency (IRR: 1.002, 95% CI: 1.00, 1.004, p = 0.03) and quantity (IRR: 1.003, 95% CI: 1.001, 1.01, p = 0.001), but not with cannabis use. There were slight differences in incident compared to prevalent tobacco frequency and quantity of use; prevalent tobacco frequency and quantity were associated with PTSD symptoms, while incident tobacco frequency and quantity were not. Using causal forests, lifetime worst use of cigarettes, overall self-rated physical health, and prior childhood trauma were major moderators of the relationship between PTSD symptoms and the three substances investigated.

Conclusion

PTSD symptoms were highly associated with tobacco and alcohol use, while the association with prospective cannabis use is not clear. Findings suggest that understanding the different risk stratification that occurs can aid in tailoring interventions to populations at greatest risk to best mitigate the comorbidity between PTSD symptoms and future substance use outcomes. We demonstrate that this is particularly salient for tobacco use and, to some extent, alcohol use, while cannabis is less likely to be impacted by PTSD symptoms across the strata.

Unhealthy behaviors associated with mental health disorders: a systematic comparative review of diet quality, sedentary behavior, and cannabis and tobacco use

Background

There are well-established literatures documenting the associations between mental disorders and unhealthy behaviors such as poor diet quality, sedentary behavior, and cannabis and tobacco use. Few studies have attempted to understand the respective findings in light of each other, however.

Objective

The purpose of this review was to assemble comparable data for each behavior-disorder association and assess the associations in terms of their overall strength. The review aimed to include a representative, but not exhaustive, range of studies that would allow for explorative comparisons.

Methods

Eligible studies were identified via Pubmed searches and citation searching, restricted to publications no older than 2015 written in English. To obtain comparable data, only studies that reported findings as odds ratios were included, and risk of bias related to study samples, behavioral measurement disparities, and control variables was assessed via sensitivity analyses. Findings for each disorder were compared on the basis of different measures of central tendency.

Results

From 3,682 records, 294 studies were included. The review found evidence of associations between each of the four unhealthy behaviors and psychosis, depression, anxiety, bipolar disorder, attention-deficit/hyperactivity disorder (ADHD), and post-traumatic stress disorder (PTSD), while personality disorder was only investigated in relation to cannabis and tobacco use. In overall comparison, the associations were generally of similar strength, and only the association between cannabis use and personality disorder was exceptional in terms of being significantly stronger than its counterparts across disorders and across behaviors. Analyses of bias risk identified some influence from behavioral measurement disparities and lack of adequate statistical control, but findings were generally robust across a range of sensitivity analyses.

Conclusion

This explorative and comparative review found that poor diet quality, sedentary behavior, and cannabis and tobacco use are about equally strongly associated with a range of different mental disorders. Given the general nature of these associations, we should probably understand them to reflect a general and shared etiology. However, the findings in this review should be regarded as tentative until confirmed by more comprehensive investigations.

The Relationship Between Posttraumatic Stress Disorder and Alcohol Misuse and Smoking Among Aging Men Who Have Sex With Men: No Evidence of Exercise or Volunteering Impact

OBJECTIVES

To determine if the association between posttraumatic stress disorder (PTSD) and substance use (alcohol misuse or smoking tobacco) is mediated/moderated by exercise or volunteering among aging (≥40 years) men who have sex with men (MSM), and if this mediation/moderation differs by HIV serostatus.

METHODS

Multicenter AIDS Cohort Study data were used. Three datasets with PTSD measured during different time periods (10/1/2017-3/31/2018, 898 men; 4/1/2018-9/30/2018, 890 men; 10/1/2018-3/31/2019, 895 men) were analyzed. Longitudinal mediation analyses estimated the mediation effect of exercise and volunteering on the outcomes.

RESULTS

Nine percent of MSM had evidence of PTSD. There was no statistically significant mediation effect of exercise or volunteering regardless of substance use outcome. The odds of smoking at a future visit among MSM with PTSD were approximately double those of MSM without PTSD. Results did not differ by HIV serostatus.

DISCUSSION

There is a particular need for effective smoking cessation interventions for aging MSM with PTSD.

[Smoking and smoking cessation among migrants in France: A qualitative study]

INTRODUCTION

The aim of this study is to identify factors related to smoking and smoking cessation as well as preferences for cessation methods reported by migrants in France.

METHODS

Qualitative study using semi-directive interviews with migrants in the Parisian area thematically analyzed using an inductive approach.

RESULTS

Sixteen interviews conducted. The stress and isolation induced by migration favor the increase of tobacco consumption. These two factors, as well as the lack of information on the resources available for quitting smoking, were identified as obstacles to cessation. The main motivations for quitting are the identified or experienced effects of smoking on their health and pressure from family members, especially children. Quitting is essentially a personal strategy centered on the true will to quit. The most popular method identified by the participants as the most effective in helping them to quit, is follow-up or therapy by a health professional combining listening and psychological support.

DISCUSSION

For migrants, smoking is a resource to combat stress that increases during the migration process and upon arrival in the host country and presents a psychosocial dimension for the most isolated individuals. Smoking cessation must be accompanied and must take into account the specificities of this population as well as the expressed need for psychosocial support, as suggested by our results, to be most effective.

Posttraumatic stress disorder and depression after the 2018 Strasbourg Christmas Market terrorist attack: a comparison of exposed and non-exposed police personnel

Background: Police personnel are among the first responders exposed to terrorist attacks, raising in number in the late decades. Due to their profession, they are also exposed to repetitive violence, increasing their vulnerability to PTSD and depression.Objective: Our study aims at comparing the prevalence of PTSD and depression, and the risk factors associated with these conditions among directly and indirectly exposed versus non-exposed police personnel during the Strasbourg Christmas Market terrorist attack.Method: Three months after the attack, participants completed a survey assessing their sociodemographic characteristics, occupational data, degree of exposure, sleep debt around the event, event centrality (CES), and three mental health conditions: PTSD (PCL-5), depression (PHQ-9), and suicide risk (yes/no questions).Results: A total of 475 police personnel responded to the questionnaire: 263 were exposed to the attack (182 of them directly) and 212 were non-exposed. Among directly exposed participants, the prevalences of partial and complete PTSD were 12.6 and 6.6%, and the prevalence of moderate-to-severe depression was 11.5%. Multivariate analysis revealed that direct exposure was associated with a higher risk of PTSD (OR = 2.98 [1.10-8.12], p = .03). Direct exposure was not associated with a higher risk of depression (OR = 0.40 [0.10-1.10], p = .08). A significant sleep debt after the event was not associated with a higher risk of later PTSD (OR = 2.18 [0.81-5.91], p = .13) but was associated with depression (OR = 7.92 [2.40-26.5], p < .001). A higher event centrality was associated with both PTSD and depression (p < .001).Conclusions: Police personnel directly exposed to the Strasbourg Christmas Market terrorist attack were at higher risk of PTSD but not depression. Efforts to prevent and treat PTSD should focus on directly exposed police personnel. However, general mental health should be monitored for every personnel member.

The Impact of Posttraumatic Stress Disorder, Ethnic Discrimination, and Nativity on Nicotine Dependence among Female Hispanic Survivors of Physical Intimate Partner Violence

Background: Nicotine dependence (ND) is an understudied public health problem among Hispanic women experiencing physical intimate partner violence (PIPV). Despite multiple calls for such studies, little is known about the associations of PTSD, ethnic discrimination, and nativity with ND among female Hispanic survivors of PIPV. Objectives: This study aimed to do the following: 1) replicate the PTSD-ND association in a sample of female Hispanic survivors of PIPV, and 2) examine the impact of ethnic discrimination and nativity on ND among 378 female Hispanic survivors of PIPV. We hypothesized that past-year PTSD and ethnic discrimination would be associated with greater odds of past-year ND (PY-ND) and being born outside the U.S. would be associated with lower odds of PY-ND. Data was used from 378 participants in the National Epidemiologic Survey on Alcohol and Related Conditions Wave 2 who were female, Hispanic, and experienced PIPV. Logistic regression was used to test the impacts of past-year PTSD, ethnic discrimination and nativity on PY-ND while controlling for past-year major depressive episode, age, and personal income. Results: Results supported our hypotheses. Specifically, past-year PTSD was associated with greater odds of PY-ND, AOR = 1.91, 95% CI [1.43-2.56], and past-year ethnic discrimination was associated with greater odds of PY-ND, AOR = 2.31, 95% CI [1.82-2.93], whereas being born outside the U.S. was associated with lower odds of PY-ND, AOR = 0.33, 95% CI [0.26-0.41]. Conclusions: Findings suggest the need for additional studies to understand how ethnic discrimination and nativity affect ND among Hispanic female survivors of PIPV.

Vaping and Mental Health Conditions in Children: An Umbrella Review

The e-cigarette (EC) epidemic began in the United States (US) in 2007; since 2014 EC is the most commonly used form of tobacco. However, the mental health implications of vaping are grossly unknown. The aim of this umbrella review is to provide astate-of-the-art summary of existing research concerning vaping and mental health conditions in children. Following the PRISMA Statement 2020 guidelines, a systematic search was conducted across PubMed, Cochrane Library, and Google Scholar up to April 15th, 2022 to locate relevant studies. The Joana Briggs Institute (JBI) methodology for umbrella reviews and quality appraisal tool was utilized. Six studies, pooling a total of 846,510 adolescents aged 21 years or below, were included by collating 85 primary clinical studies. Of these, 58.8% of the primary clinical studies originated in the US, with 4.7% from Canada, South Korea, and the United Kingdom each; 3.5% each from England and Taiwan; 2.4% each from Australia, France, Hawaii, Mexico, and Russia; and 1.2% each from Denmark, Greece, Hong Kong, Iceland, New Zealand, Poland, and Switzerland. Overall, significant associations were found between mental health outcomes, including depression and suicidality, among current EC users and those who had ever used EC. Compared to adolescents who had never used EC, both depression and anxiety were reportedly higher among EC users. Impulsive behaviors, reported as impulsivity, were also found to be correlated with the adoption of EC use. However, there is a lack of evidence regarding the impact of EC use on mental health outcomes in children. This umbrella review highlights the urgent need to further explore the effects of current EC use from a psychiatric and public health perspective.

Posttraumatic stress disorder strengthens the momentary associations between emotion dysregulation and substance use: a micro-longitudinal study of community women experiencing intimate partner violence

BACKGROUND AND AIMS

A fast-growing body of literature linking emotion dysregulation to substance use has almost exclusively relied on cross-sectional designs and has generally failed to assess dysregulation stemming from positive emotions. The current study measured the momentary associations between both negative and positive emotion dysregulation and substance use, as well as the moderating role of post-traumatic stress disorder (PTSD).

DESIGN

Micro-longitudinal momentary data were collected three times per day for 30 days using phone-based interactive voice recording.

SETTING

Northeastern United States.

PARTICIPANTS

A total of 145 community women (M, age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances were recruited from 2018 until 2020.

MEASUREMENTS

Momentary surveys assessed negative and positive emotion dysregulation and alcohol, drug, and cigarette use. PTSD diagnosis was derived from a structured diagnostic interview.

FINDINGS

Between-person relations that remained significant after covariate adjustment and correction for multiple testing were found for negative emotion dysregulation and both number of drinks (internal rate of return [IRR] = 1.45; 95% CI = 1.07, 1.93; β = 0.37) and drug use (OR = 3.78; 95% CI = 1.86, 7.69; β = 1.33), and positive emotion dysregulation and number of cigarettes (OR = 1.40; 95% CI = 1.07, 1.82; β = 0.34). Of six interactions tests, PTSD was only shown to moderate the within-person relation between positive emotion dysregulation and drug use, even after controlling for relevant covariates and adjusting for multiple testing (OR = 1.26; 95% CI = 1.04, 1.51; β = 0.23), such that women experiencing intimate partner violence with versus without PTSD were more likely to use drugs when experiencing periods of elevated positive emotion dysregulation.

CONCLUSIONS

Women experiencing intimate partner violence with higher levels of negative dysregulation relative to others may use more alcohol and be more likely to use drugs. Women experiencing intimate partner violence with higher levels of positive dysregulation relative to others may use more cigarettes. Women experiencing intimate partner violence who also have posttraumatic stress disorder may be more likely to use drugs when experiencing momentary elevated levels of positive emotion dysregulation than those who do not also have posttraumatic stress disorder.

The Intertwining of Posttraumatic Stress Symptoms, Alcohol, Tobacco or Nicotine Use, and the COVID-19 Pandemic: A Systematic Review

BACKGROUND

Posttraumatic stress symptoms (PTSSs) and alcohol, tobacco, or nicotine use are frequently associated conditions. The COVID-19 pandemic has been a stressful situation globally and has worsened mental health conditions and addictions in the population. Our systematic review explores the links between PTSSs and (1) alcohol use and (2) tobacco or nicotine use during the COVID-19 pandemic.

METHODS

We searched the PubMed, PsycINFO, and Web of Science databases for studies published between January 2020 and 16 December 2021. We included studies published in English concerning adults or adolescents. Included articles dealt simultaneously with the COVID-19 pandemic, PTSSs, and alcohol, tobacco, or nicotine use. The reports included were cross-sectional, longitudinal, or cohort studies. We categorized the reports according to the population explored. Our main outcomes are the impacts of PTSSs on (1) alcohol use and (2) tobacco and nicotine use and their relation to COVID-19-related stressors (worries, exposure, lockdown, and infection, either of self or relatives).

RESULTS

Of the 503 reports identified, 44 were assessed for eligibility, and 16 were included in our review, encompassing 34,408 participants. The populations explored were the general population, healthcare workers, war veterans, patients with substance use disorders, and other vulnerable populations. Most studies were online surveys (14) with cross-sectional designs (11). Every study explored alcohol use, while only two assessed tobacco use. In most populations explored, a high level of PTSSs was associated with alcohol use increase. COVID-19-related stress was frequently correlated with either high PTSSs or alcohol use. In healthcare workers, PTSSs and alcohol use were not associated, while COVID-19 worries were related to both PTSSs and alcohol use.

DISCUSSION

1. PTSSs and increased alcohol use are frequently associated, while COVID-19 worries might trigger both conditions and worsen their association. Alcohol use increase may represent either an inadequate way of coping with PTSSs or a vulnerability amid the COVID-19 pandemic, leading to PTSSs. As most studies were cross-sectional online surveys, longitudinal prospective studies are needed to ascertain the direction of the associations between these conditions. These studies need to be sufficiently powered and control for potential bias and confounders. 2. Our review highlighted that research about PTSSs and tobacco or nicotine use is scarce.

Patient Perspectives on Medical Trauma Related to Inflammatory Bowel Disease

Post-traumatic stress symptoms (PTSS) in response to medical trauma are understudied in inflammatory bowel disease (IBD). Two studies identify surgery, hospitalizations, and disease severity as risk factors. We aimed to document IBD-related patient experiences and how these relate to PTSS via a qualitative study. Adult patients with confirmed IBD recruited from two gastroenterology clinics underwent a semi-structured interview with a psychologist and completed the Post Traumatic Stress Disorder Symptom Scale for DSM5 (PSSI-5). Interviews were analyzed using an interpretive phenomenological approach. Themes and subthemes with representative quotations were documented based on thematic saturation. 16 participants, five met PSSI-5 criteria for PTSD. Five themes emerged: disease uncertainty, information exchange/quality, medical procedures, surgery, and coping. Patients with IBD may experience medical PTSS from several sources. Information, communication, and trust in clinicians is vital but may be sub-optimal. Both adaptive and maladaptive coping strategies are used to mitigate PTSS.

Smoking cessation among people with mental illness: A South African perspective

Tobacco use is recognised as a serious, worldwide public health concern. Smoking cessation is of great interest across a wide range of medical specialities, including family medicine. However, smoking cessation among people with mental illness (PWMI) has attracted scant attention in South African literature. This is despite PWMI suffering disproportionately from the damages of tobacco. The harms of smoking are not limited to physical health but extend to mental health. This article discusses the need for multifaceted smoking cessation treatments for PWMI in the public health sector, taking into consideration the prevalence and unique drivers of smoking in this population. A brief overview of patterns of tobacco use, associated harms and smoking cessation interventions in South Africa is given; all within the context of mental illness.

Association of Sociodemographic and Psychosocial Factors With COVID-19-Related Post-Traumatic Stress Disorder Risk Group Among Medical Students

OBJECTIVE

Several previous studies have reported the negative psychological impact of the coronavirus disease (COVID-19) pandemic on medical students worldwide. This study investigated the sociodemographic and psychosocial factors associated with COVID-19-related post-traumatic stress disorder (PTSD) risk among medical students in Daegu, a region that experienced a high concentration of infections.

METHODS

A total of 270 students completed the self-reported questionnaires including COVID-19 exposure, psychological measurement, and sociodemographic factors. We evaluated the COVID-19-related PTSD risk group using the Korean version of the Impact of Event Scale-Revised. Logistic regression analysis was performed to evaluate the odds ratio for the COVID-19-related PTSD risk group in sociodemographic and psychosocial factors.

RESULTS

The prevalence of the COVID-19-related PTSD risk group was 10.4% in medical students. Among sociodemographic factors, lower grades (specially, first-year medical students) and current smokers were associated with the COVID-19-related PTSD risk. Indirect exposure to COVID-19 was also associated with this risk. Meanwhile, having higher resilience, self-esteem, and social support were less likely to be associated with COVID-19-related PTSD risk.

CONCLUSION

This study suggested that it is necessary to develop a system for the screening and managing of COVID-19-related PTSD risk group among medical students, especially high-risk groups during the COVID-19 pandemic.

Alcohol Consumption and Smoking During Covid-19 Pandemic: Association with Sociodemographic, Behavioral, and Mental Health Characteristics

The Covid-19 pandemic is related to increased alcohol consumption and smoking. These behaviors may be related to several sociodemographic, behavioral and mental health factors. Thus, the aim of this study was to assess the association between alcohol consumption and cigarette smoking with sociodemographic, behavioral and mental health characteristics. This study used data from two population-based studies conducted in two cities from Southern Brazil amid the Covid-19 pandemic. Individuals aged 18 years or older were included and selected using a multistage sampling procedure. Alcohol consumption and smoking and changes in such consumption during the Covid-19 pandemic were evaluated. Sociodemographic, behavioral, pandemic-related, and mental health variables were also included. A hierarchical model was used to conduct the adjusted analyses, and Poisson regression with robust adjustment was used for variance. A total of 2170 individuals were studied. The prevalence of alcohol consumption and smoking were 9.3% and 14.2%, respectively. The rates of increase in alcohol consumption and smoking during the Covid-pandemic were about 20% and 30%, respectively. They were higher among those with depressive symptoms, feeling of sadness and self-reported stress. Those with poor diet quality had higher prevalence of alcohol consumption (PR: 1.82) and were 1.58 times more likely to smoke. The findings may help stakeholders in health and political systems to better understand the consequences of the Covid-19 pandemic and develop strategies to mitigate these consequences in Brazil and elsewhere.

The association between BDNF C270T genetic variants and smoking in patients with mental disorders and in healthy controls

Studies investigating the association between smoking and the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism have reported inconclusive results, while the studies on the association of smoking status with BDNF C270T polymorphism are missing. We aimed to determine the association of smoking and BDNF Val66Met and C270T genetic variants in control subjects and patients with mental disorders. This study included 3502 Caucasian subjects: 918 healthy controls and 2584 patients with mental disorders (519 individuals with posttraumatic stress disorder (PTSD), 419 patients with depression, 996 patients with schizophrenia, and 650 patients with alcohol dependence). The frequency of the BDNF Val66Met and C270T variants were presented in codominant, dominant and recessive models. BDNF C270T, but not BDNF Val66Met polymorphism, was significantly associated with smoking in all groups, since the presence of the C270T T allele was more frequently found in smokers compared to non-smokers. Significant predictors of smoking were sex, age and BDNF C270T genetic variants. However, after detailed analysis of the separate diagnostic entities, the significant association of BDNF C270T polymorphism was confirmed only in healthy subjects, but not in patients with mental disorders; and was not related to number of cigarettes smoked per day. In patients with alcohol dependence, the severity of smoking was significantly associated with BDNF Val66Met variants. This is a first report of the significant association between the BDNF C270T polymorphism and smoking status in the large groups of Caucasian cases/controls.

[Comorbidity of posttraumatic stress disorder and addiction from a biopsychosocial perspective]

Posttraumatic stress disorder and substance use disorder often co-occur within the health care system. Their comorbidity is associated with more serious acute clinical symptomatology, more frequent hospital admissions in state of emergency and significantly lower chances of improvement by psychological and pharmacological treatment. Their comorbidity contributes to dramatically unfavourable courses of illness as regards all biopsychosocial levels. The survey presented will discuss empirical findings from various perspectives: general epidemiology, substance use disorder as risk factor of trauma and PTSD, trauma and PTSD as risk factor of SUD, neurobiological effects of SUD converging towards neurobiology of PTSD, shared common factors of genetics/epigenetics, personality traits, and early developmental stress and trauma. The main focus of analysis will be put on processes that are intrinsically linked to the development and course of both disorders.

Understanding the Impact of COVID-19 on Tobacco and Nicotine Use among Young Adults Identified as Sexual and Gender Minorities: A Mixed Methods Approach

We investigated the perceived impact of COVID-19 on changes in tobacco and nicotine (NT) use among sexual and gender minority (SGM) young adults. We used a mixed methods approach that included closed- and open-ended survey questions and in-depth interviews. Participants were 53 SGM young adults in California who reported current or past cigarette smoking. Of study participants, 63% (n=33) reported any changes in their NT use, and of those, 60% reported initial increase of NT use. Content analysis of an open-ended survey question revealed three reported reasons for changes in NT use: (1) changes in routine activities (27%), (2) stress (46%), and (3) health (24%). Thematic analysis of qualitative interviews identified several related themes: (1) in discussions of increased NT use, stress and boredom/free time were important aspects of changes to daily routines, (2) fluctuations in NT use behaviors occurred over time, (3) reasons for NT changes were multiple and intertwined, and (4) NT use changes were shaped by experiences related to intersectional forms of structural and social stigmatization. Results reveal the dynamic and complex ways in which participants described their pandemic-related changes in NT use-nuance that is crucial for compassionate and participant-centered approaches to tobacco prevention and cessation.

Gaming to cope: Applying network analysis to understand the relationship between posttraumatic stress symptoms and internet gaming disorder symptoms among disaster-exposed Chinese young adults

Research has demonstrated that posttraumatic stress disorder (PTSD) is associated with internet-related problematic behaviors. However, studies have not explored the linkage between PTSD symptoms and internet gaming disorder (IGD) symptoms. The current study aimed to investigate the relationship between posttraumatic stress symptoms (PTSS) and IGD symptoms via network analysis. We conducted a cross-sectional study with 341 Chinese young adults directly exposed to a typhoon and examined the network structure of PTSS and IGD symptoms, along with bridge symptoms, to elucidate how they co-occur. Results indicated that 'avoiding external reminders' and 'anhedonia' were identified as the most central symptoms in the PTSD network, whereas 'preoccupation,' 'gaming despite harms', and 'loss of control' ranked highest on centrality in the IGD network. Two bridge symptoms emerged within the combined PTSD and IGD network model: 'concentration difficulties' and 'conflict due to gaming' from among the PTSS and IGD symptoms, respectively. These findings reveal novel associations between PTSS and IGD symptoms and provide an empirically-based hypothesis for how these two disorders may co-occur among individuals exposed to natural disasters.

Exploring the Role of Traumatic Event Exposure in Tobacco Dependence Treatment Outcomes Among African Americans

African Americans are more likely to die from tobacco-related diseases and less likely to quit smoking than their white counterparts. Evidence of greater prevalence of posttraumatic stress disorder (PTSD) among African Americans underscores the importance of studying the effects of traumatic event exposure on tobacco dependence treatment outcomes in this group. In this secondary analysis of data from a previously completed randomized control trial, we examined the effects of traumatic event exposure (e.g., serious accident) on tobacco dependence treatment outcomes, as well its moderating effects on the effectiveness of an adapted smoking cessation treatment, in a sample (n = 169) of African American smokers in New York City. Traumatic event exposure did not have a significant impact on tobacco treatment outcomes and did not moderate the relationship between treatment type and outcomes in this sample. While results may be driven by unique sample characteristics, they may also indicate that an average level of traumatic event exposure does not significantly impact tobacco treatment outcomes among African Americans. Future research should examine the effects of higher levels of traumatic event exposure on treatment outcomes, as well as investigating the factors underlying trauma-exposed individuals' difficulties with reducing/quitting smoking in a larger, more diverse African American sample.

Post-traumatic stress disorder among persons with HIV who engage in heavy alcohol consumption in southwestern Uganda

BACKGROUND

We aimed to describe the prevalence of PTSD symptoms and its associated factors in persons living with HIV (PLWH) in Uganda who engage in heavy alcohol use.

METHODS

We analyzed baseline data from the Drinkers Intervention to Prevent Tuberculosis study which enrolls PLWH with latent tuberculosis who engage in heavy alcohol consumption. Using the primary care Post Traumatic Stress Disorder (PTSD) screening scale from the DSM-5 (PC-PTSD-5), probable PTSD was defined as reporting ≥3 of 5 assessed symptoms. We conducted the Alcohol Use Disorders Identification Test-Consumption and assessed demographics, smoking, symptoms of depression, and spirituality/religiosity.

RESULTS

Of 421 participants enrolled from 2018 through 2020, the majority (68.2%) were male, median age was 40 years (interquartile range [IQR]: 32-47), and median AUDIT-C score was 6 [IQR: 4-8]. Half (50.1%) of the participants reported ever experiencing a traumatic event, and 20.7% reported ≥3 symptoms of PTSD. The most commonly reported PTSD symptoms in the past 1 month in the entire sample were avoidance (28.3%), nightmares (27.3%), and being constantly on guard (21.6%). In multivariable logistic regression analyses, level of alcohol use was not associated with probable PTSD (adjusted odds ratio [AOR] for each AUDIT-C point: (1.02; 95% CI: 0.92-1.14; p = 0.69); however, lifetime smoking (AOR 1.89; 95% CI: 1.10-3.24) and reporting symptoms of depression (AOR 1.89; 95% CI: 1.04-3.44) were independently associated with probable PTSD.

CONCLUSIONS AND RECOMMENDATIONS

A history of traumatic events and probable PTSD were frequently reported among persons who engage in heavy drinking, living with HIV in Uganda. Level of alcohol use was not associated with probable PTSD in this sample of PLWH with heavy alcohol use, however other behavioral and mental health factors were associated with probable PTSD. These data highlight the high prevalence of PTSD in this group, and the need for screening and interventions for PTSD and mental health problems.

The Relationship Between Trauma Exposure and Adult Tobacco Use: Analysis of the National Epidemiologic Survey on Alcohol and Related Conditions (III)

INTRODUCTION

Previous research has examined cigarette smoking in trauma exposed populations. However, the relationships between trauma exposure and use of other tobacco products (eg, cigars, e-cigarettes) and specific trauma exposure characteristics that may be associated with tobacco use are understudied.

AIMS AND METHODS

Using the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (N = 36 151 adults), we conducted weighted bivariate analyses of tobacco use among participants with no trauma exposure, trauma exposure, and trauma exposure with post-traumatic stress disorder (trauma + PTSD), stratified by tobacco product use. We also performed weighted logistic regressions testing relationships between trauma exposure and tobacco use, controlling for behavioral health (BH) conditions (mood, anxiety, substance use, personality disorders) and sociodemographics.

RESULTS

Approximately 44% of participants had experienced trauma; 6% experienced trauma + PTSD. Trauma exposed participants had a higher prevalence of tobacco use (30%--46% vs. 22%) and poly-tobacco use (34%--35% vs. 28%) than unexposed participants. Cigarettes were the most used tobacco product; trauma + PTSD (19%), and trauma (15%) participants had a higher prevalence of e-cigarette use than unexposed participants (11%). Trauma exposure was associated with current tobacco use (AOR = 1.36 trauma + PTSD; 1.23 trauma) (but not former use), particularly among participants exposed to violence/abuse (AOR = 1.23). Personality and substance use disorders were strongly associated with current and former tobacco use.

CONCLUSIONS

Trauma exposure, PTSD, and experiences of violence/abuse are associated with current tobacco use. BH conditions may also play a role in current and former tobacco use. Recognizing and addressing trauma exposure and BH conditions among tobacco users may improve cessation rates in these populations.

IMPLICATIONS

This study contributes to research on tobacco use disparities in behavioral health populations by providing a comprehensive examination of tobacco use in trauma exposed individuals. Prior research has examined cigarette smoking, but not other tobacco product use in these populations. This study presents findings on multiple tobacco use behaviors (tobacco product, poly-tobacco use, cessation attempts) in trauma exposed populations and characteristics of trauma exposure (severity, type of traumatic event) associated with tobacco use. These findings underscore the importance of further examining the implications of trauma exposure for tobacco use and of screening and addressing trauma in cessation treatment.

Effectiveness of drugs acting on adrenergic receptors in the treatment for tobacco or alcohol use disorders: systematic review and meta-analysis

AIM

To assess the efficacy of drugs directly acting on alpha- and beta-adrenergic receptors in the treatment of patients suffering from tobacco or alcohol use disorder.

METHODS

Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, studies were identified through PUBMED, EMBASE, the Cochrane Central Register of Controlled Trials and clinicaltrial.gov. We selected only randomized controlled trials with adult patients with tobacco or alcohol use disorders according to DSM-5 criteria. Interventions included any molecule having a direct pharmacological action on alpha- or beta-adrenergic receptors (agonist or antagonist). Comparators were placebo or other validated pharmacotherapies. The duration of the intervention was a minimum of 1 month, with 3 months of follow-up. Measurements included smoking cessation for tobacco; for alcohol, we selected abstinence, alcohol consumption (drinks per day or week) and heavy drinking days (HDD). Ten studies with tobacco and six with alcohol use disorder were included in the qualitative synthesis and fifteen studies in the quantitative analysis.

RESULTS

We found that clonidine, an alpha-2 agonist, significantly increased smoking abstinence [relative risk = 1.39 with a 95% confidence interval (CI) = 1.04, 1.84]. Beta-blockers had no significant effect on smoking abstinence. The alpha-1 antagonists prazosin and doxazosin decreased alcohol consumption [SMD = -0.32 (-0.56, -0.07)] but had no effect on abstinence or HDD.

CONCLUSIONS

The noradrenaline system may represent a promising mechanism to target in tobacco and alcohol use disorders.

Factors associated with increased cigarette consumption in the Brazilian population during the COVID-19 pandemic

Social distancing measures adopted in various countries to mitigate the impact of the COVID-19 pandemic can lead to unwanted effects on their populations' health and behaviors. This study aimed to investigate smoking behavior in the Brazilian adult population during the COVID-19 pandemic and analyze factors associated with the increase in cigarette consumption. An online survey was performed, and the final sample included 45,160 individuals. The study used post-stratification weights and calculated crude prevalence ratios (PR) and adjusted by sex, age, and schooling, and respective 95% confidence intervals (95%CI). Poisson regression models with robust variance were applied to analyze associations between increased cigarette consumption and sociodemographic variables and adherence to social distancing, quality of sleep, state of mind, and changes in work and earnings. Prevalence of smokers was 12% (95%CI: 11.1-12.9), 34% of whom reported an increase in cigarette consumption. The increase was greater among women (PR = 1.27; 95%CI: 1.01-1.59) and individuals with incomplete secondary schooling (PR = 1.35; 95%CI: 1.02-1.79). The increase in cigarette consumption was associated with worse quality of sleep, feeling isolated from family members or sad, depressed, or anxious, loss of earnings, and worse self-rated health. Health promotion strategies, smoking prevention, and encouragement for smoking cessation, as well as mental health interventions, should be continued and reinforced in the context of social distancing during the COVID-19 pandemic.

Relationship of trauma exposure and PTSD to cigarette smoking prevalence, frequency, and quantity: Data from a nationally representative sample of U.S. adults

Individuals with Post-Traumatic Stress Disorder (PTSD) smoke cigarettes at much higher prevalences than the general population. Less is known about PTSD and other smoking behaviors (e.g., smoking quantity and frequency) or about smoking among individuals who experience trauma.

OBJECTIVE

To examine differences in cigarette smoking behaviors among adults in the United States (a) with no exposure to trauma or PTSD, (b) with trauma but no PTSD, and (c) with PTSD.

METHODS

Data came from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions-II (NESARC-II, 2004-2005) and included demographics, PTSD diagnoses, traumatic events, and smoking behaviors. Odds ratios and group differences in smoking prevalence and behaviors based on PTSD diagnoses and exposure to traumatic experiences were calculated.

RESULTS

Traumatic events and PTSD diagnoses were both associated with greater smoking prevalences than persons without trauma or PTSD. Individuals with PTSD who smoke were more likely to report daily smoking than those without PTSD who smoke (Cohen's d = 0.19). Cigarette users with either trauma or PTSD smoked more cigarettes per day than cigarette users without trauma or PTSD (Cohen's d = 0.35). US adults with trauma exposure or PTSD have higher smoking prevalences and more intense smoking behaviors than those without PTSD or trauma.

CONCLUSION

Trauma or PTSD may each serve as a clinical indicator of increased risk of cigarette smoking-related health problems and prompt the implementation of targeted interventions to reduce the harms of smoking. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Tobacco use and associated mental symptoms and health risk behaviours amongst individuals 15 years or older in South Africa

Background

Tobacco use may deteriorate mental health and increase health risk behaviours.

Aim

The aim of this investigation was to identify associations between tobacco use and mental illness symptoms and health risk behaviours in individuals 15 years or older in South Africa.

Setting

Community-based national population sample in South Africa.

Methods

Cross-sectional data were analysed from the 'South African National Health and Nutrition Examination Survey (SANHANES-1) 2012', using a sample of 15 310 individuals 15 years or older (median age 33 years). Measures included information on tobacco use, sociodemographic factors, mental symptoms and health risk behaviour.

Results

Compared to non-tobacco users, daily tobacco users were associated with psychological distress and post-traumatic stress disorder (PTSD) in adjusted logistic regression analysis, and with sleeping problems in unadjusted analysis. Past tobacco use, less than daily, and daily tobacco use were highly associated with a drinking problem. In terms of dietary variables, less than daily and daily tobacco use increased the odds of inadequate fruit intake and salty food intake, and daily tobacco use decreased the odds of fast food consumption. Past tobacco use, less than daily, and daily tobacco use were inversely associated with physical inactivity, and daily tobacco use was associated with not always washing hands before eating.

Conclusions

The study showed that compared to non-tobacco users, daily tobacco users had significantly poorer mental health (psychological distress and PTSD) and increased odds for several health risk behaviours (drinking problem, inadequate fruit intake, salty food consumption and not always washing hands before eating) as compared to non-tobacco users.

Cross-lagged effects of posttraumatic stress disorder symptom severity and cigarette smoking among OEF/OIF/OND veterans

OBJECTIVES

Veterans with posttraumatic stress disorder (PTSD) are known to smoke cigarettes at elevated levels in comparison to both veterans without PTSD and civilians. This study aims to elucidate how cigarette smoking and PTSD symptoms interact over time.

MATERIALS AND METHODS

This study examined the directionality and strength of the relationship between average daily cigarette smoking and PTSD symptom severity across three (T1-T3) time points in a large cohort (N = 851) of male and female Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn returning veterans who were either current or former smokers at T1 (mean age = 37.56; standard deviation = 10.10). We used cross-lagged panel analyses to evaluate their temporal relations.

RESULTS

The analyses indicated that PTSD symptom severity at T1 significantly predicted cigarette smoking at T2, and this predictive association was maintained from T2 to T3. Conversely, smoking at T1 and T2 did not predict PTSD symptom severity at T2 and T3, respectively. Although effect sizes were small, PTSD symptom severity was cross-sectionally related to smoking at T1 and T2, but not T3. In addition, when analyses were examined by gender, the same results were found except these associations were stronger for women than for men cross-sectionally.

CONCLUSION

Our findings provide some evidence of a longitudinal association between PTSD symptom severity and tobacco use and highlight potential targets of intervention.

Alcohol/substance use and occupational/post-traumatic stress in paramedics

Background:

Paramedics work in high-pressure environments and experience traumatic events, which contribute to high levels of occupational and post-traumatic stress. Such stress can result in alcohol and substance misuse in other health professionals, but this relationship has not been examined in paramedics. This review is the first exploration of the literature on this.

Methods:

A systematic literature review was conducted using PRISMA guidelines, with databases searched using terms relevant to paramedics and alcohol/substance use. Studies were analysed using descriptive statistics for quantitative data and thematic analysis for qualitative information.

Findings:

Eleven studies were identified. Nine studies examined alcohol use; seven examined substance use; five examined both. Alcohol and smoking may be linked to occupational stress.

Conclusions:

The nature and extent of alcohol and substance use in relation to occupational and post-traumatic stress among paramedics need further investigation to facilitate advice and support.

Trauma exposure, PTSD symptoms, and tobacco use: Does church attendance buffer negative effects?

Traumatic stress and posttraumatic stress disorder (PTSD) are overrepresented in urban African American communities, and associated with health risk behaviors such as tobacco use. Support and resources provided by churches may reduce trauma-related health risks. In the current study, we assessed weekly church attendance as a moderator of relations between (a) traumatic event exposure and probable PTSD, and (b) probable PTSD and tobacco use. Data were drawn from a health surveillance study conducted in seven churches located in Chicago's West Side. Participants (N = 1015) were adults from churches as well as the surrounding community. Trauma exposure was reported by 62% of participants, with 25% of those who experienced trauma reporting probable PTSD. Overall, more than one-third of participants (37.2%) reported current tobacco use. As compared with non-weekly church attendance, weekly church attendance was associated with a lower likelihood of PTSD (odds ratio [OR] = 0.41; 95% confidence interval [CI] = 0.26-0.62; p < .0001) and lower tobacco use overall (OR = 0.22; 95% CI = 0.16-0.30; p < .0001), but did not moderate the effect of trauma exposure on risk of PTSD, or the effect of PTSD on tobacco use. Findings support church attendance as a potential buffer of trauma-related stress.

Motives for Smoking in Those With PTSD, Depression, and No Psychiatric Disorder

Objective: Approaches for effectively treating smoking in those with posttraumatic stress disorder (PTSD) and with major depressive disorder (MDD) could be improved by identifying motivational processes underlying their tobacco dependence. The goal of this study was to identify the motivational processes influencing smoking dependence among smokers with PTSD and with MDD relative to non-diagnosed controls. Methods: Participants were United States (US) veterans who smoked daily (N = 162) and met DSM-IV criteria for either PTSD (n = 52), MDD (n = 52), or no current psychiatric disorder (controls; n = 58). Smoking dependence motives were assessed via the Brief Wisconsin Inventory for Smoking Dependence Motives (Brief WISDM). The 11 Brief WISDM subscales are categorized into two major factors: Primary Dependence Motives and Secondary Dependence Motives. Results: Smokers with PTSD scored higher than non-diagnosed controls on the following Primary Dependence Motives subscales: Automaticity, Craving, and Tolerance (all p-values <.05). Smokers with PTSD, relative to controls, also scored higher on the overall Secondary Dependence Motives subscale, and on five of the seven Secondary Dependence Motives subscales: Cue Exposure/Associative Processes, Affective Enhancement, Affiliative Attachment, Cognitive Enhancement, and Weight Control (all p-values < .05). Smokers with MDD scored significantly higher than controls on one Primary Dependence Motives subscale: Craving and on four of seven Secondary Dependence Motives subscales: Affective Enhancement, Affiliative Attachment, Cognitive Enhancement, and Weight Control (all p-values <.05). Finally, exploratory analyses directly contrasting the PTSD group with the MDD group showed that smokers with PTSD were higher than those with MDD in the overall Secondary Dependence Motives subscale and one of the seven Secondary Dependence Motives subscales: Cue Exposure/Associative Processes (all p-values < .05). Conclusions: Results suggest that both Primary Dependence Motives and Secondary Dependence Motives play a meaningful role in motivation to use tobacco in smokers with PTSD; smoking dependence in those with MDD may be primarily influenced by Secondary Dependence Motives.

Tobacco Use and Cognitive Functioning in Veterans of the Conflicts in Iraq and Afghanistan

Tobacco use is a prevalent problem in the general population as well as among military veterans. Despite the fact that tobacco users are at an increased risk of many medical and psychiatric comorbidities, the risk of cognitive impairment in younger active tobacco users is less studied. Military veterans from the conflicts in Iraq and Afghanistan (n = 113) were administered a neuropsychological protocol. Even after controlling for the severity of PTSD symptoms, tobacco use was negatively related to performance on measures of processing speed, memory, and executive functioning. The current findings have implications for the neuropsychological evaluation of tobacco users.

Patient-reported Outcomes in Facial Reconstruction: Assessment of FACE-Q Scales and Predictors of Satisfaction

Background

There is a paucity of patient-reported outcome measures for facial trauma reconstruction. To measure satisfaction and health-related quality of life (HRQOL), following repair of traumatic facial fractures, we used the FACE-Q, a set of patient-reported outcome instruments designed for aesthetic facial surgery. As a step toward validating the scales for facial trauma, we evaluated their reliability.

Methods

This is a prospective study of patients following primary repair of traumatic facial fractures at a level 1 trauma center from 2016 to 2018. Six FACE-Q scales with relevance to the facial trauma population were completed by patients at their 1-month postoperative visits. Predictors of satisfaction were examined using multiple linear regression models. Reliability of the scales in this population was evaluated using psychometric methods.

Results

One hundred eighty-five participants fulfilled inclusion criteria. Mean scores for the 6 scales ranged from 59 (SD = 15) for Recovery-Early Life Impact to 94 (SD = 13) for Satisfaction with Medical Team. Predictors of lower satisfaction and/or HRQOL include current tobacco smoking status, mandibulomaxillary fixation, and Le Fort pattern fractures. All scales were found to have good to excellent reliability (Cronbach's alpha = 0.824-0.969).

Conclusions

Following repair of facial fractures, patient-reported outcomes can be reliably measured using FACE-Q scales. On average, patients report poor health-related quality of life in the early postoperative period. Predictors of low satisfaction and/or poor HRQOL include current smoking habit, mandibulomaxillary fixation, and Le Fort fractures.
