PTSD symptoms, potentially traumatic event exposure, and binge drinking: a prospective study with a national sample of adolescents

Research demonstrates substantial comorbidity between PTSD and alcohol use disorders. Evidence for functional relationships between PTSD and problematic alcohol use has not always been consistent, and there have been few investigations with adolescent samples. Further, research has not consistently controlled for cumulative potentially traumatic event (PTE) exposure when examining prospective relationships between PTSD and problematic alcohol use (i.e., binge drinking). This study examines the prospective relationships between PTSD symptoms, problematic alcohol use, and cumulative PTE exposure measured at three time points over approximately three years among a nationally representative sample of adolescents exposed to at least one PTE (n = 2399 and age range = 12–17 at Wave 1). Results from parallel process latent growth curve models demonstrated that increases in cumulative PTE exposure over time positively predicted increases in both PTSD symptoms and binge drinking, whereas increases in PTSD symptoms and increases in binge drinking were not related when controlling for the effect of cumulative PTE exposure. Further analyses suggested that these relationships are specific to assaultive PTEs and are not found with non-assaultive PTEs. Theoretical implications are discussed.     

Trauma, PTSD, and physical health: an epidemiological study of Australian Vietnam veterans

OBJECTIVE: This study aimed to examine the relative contributions to physical health of combat trauma exposure and posttraumatic stress disorder (PTSD), which have both been implicated separately in poorer physical health but whose unconfounded effects have not been teased out. METHODS: Data from an epidemiological study of Australian Vietnam veterans, which used personal interviews and standardized physical and psychiatric health assessments, provided the means to assess the independent and joint effects of psychological trauma exposure and PTSD on a wide range of self-reported measures of physical health. Trauma exposure was measured by published scales of combat exposure and peritraumatic dissociation. Logistic regression modeling was used to assess the relative importance of trauma exposure and PTSD to health while controlling for a set of potential confounders including standardized psychiatric diagnoses. RESULTS: Greater health service usage and more recent health actions were associated more strongly with PTSD, which was also associated with a range of illness conditions coded by the World Health Organization International Classification of Diseases, 9th Edition (asthma, eczema, arthritis, back and other musculoskeletal disorders, and hypertension) both before and after controlling for potential confounders. In contrast, combat exposure and peritraumatic dissociation were more weakly associated with a limited number of unconfounded physical health outcomes. CONCLUSIONS: This study provided evidence that PTSD, rather than combat exposure and peritraumatic dissociation, is associated with a pattern of physical health outcomes that is consistent with altered inflammatory responsiveness.     

Relationship violence victimization and binge drinking trajectories among a nationally representative sample of adolescents

The present study evaluated the impact of relationship violence (RV) victimization on the longitudinal trajectory of binge drinking (BD) among 3614 US adolescents (51.2% male) who participated in an initial telephone interview regarding physical and sexual RV victimization and binge drinking. Two follow-up phone interviews were completed over approximately three years. Multilevel modeling revealed small, but significant, increases in BD over time; older adolescents and those who had ever experienced RV victimization were more likely to report BD at Wave 1 compared to younger adolescents and non-victims. Although new RV victimization reported during the study predicted an increase in the likelihood of BD at that occasion, those who had ever experienced RV victimization were less likely to report BD over time compared to non-victims. Contrary to expectations, no sex differences emerged. Findings indicate that BD may precede RV. Interventions to reduce alcohol-related RV may be especially useful in this population.     

Alcohol use among 10th-graders: Distinguishing between high-intensity drinking and other levels of use

IntroductionDrinking at levels beyond standard binge drinking thresholds poses particularly high risks to youth. Few studies have examined high-intensity drinking (HID; 10+ drinks in a row) in high school students and none have tested whether peer drunkenness and parental knowledge (e.g., about youth's whereabouts) distinguish between binge and high-intensity drinkers.MethodsWe used data from the Monitoring the Future study collected from nationally-representative samples of U.S. 10th graders (modal age 16 years old) in 2016–2018 (n = 14,824; 48.3% girls, 46.8% boys). We conducted multinomial logistic regression to examine odds of drinking at one of four mutually-exclusive levels: HID in the past 2 weeks, binge (5+) drinking in the past 2 weeks, any alcohol use in the past year, and no alcohol use in the past year.ResultsLow parental knowledge and peer drunkenness were both associated with higher odds of each drinking level, including HID vs. binge, binge vs. alcohol use, and alcohol use vs. no alcohol use. Boys had higher odds than girls of HID compared to binge drinking and of no alcohol use compared to alcohol use.ConclusionsParent and peer risk factors differentiate HID from other levels of drinking.     

Hyper-brain connectivity in binge drinking college students: a diffusion tensor imaging study

The current study used diffusion tensor imaging to examine patterns/degree of brain connectivity in 12 college-aged binge drinking (BD) and 12 moderate drinking individuals. Voxel-level and region-of-interest analyses revealed increased connectivity of the BD brain in the right corona radiata, right external capsule, and both the right and left cingulum. Also, fractional anisotropy and axial diffusivity values of these regions correlated with a number of drinking behaviors of the BD as well as both groups combined. It is hypothesized that increased connectivity in the BD may produce difficulties with regulatory control, contributing to their propensity to binge.     

Social support,posttraumatic cognitions,and PTSD: The influence of family,friends, and a close other in an interpersonal and non-interpersonal trauma group

Research has suggested that social support can shape posttraumatic cognitions and PTSD. However, research has yet to compare the influence of separate domains of support on posttraumatic cognitions. Multiple-group path analysis was used to examine a model in a sample of 170 victims of intimate partner violence and 208 motor vehicle accident victims in which support from friends, family, and a close other were each predicted to influence posttraumatic cognitions, which were in turn predicted to influence PTSD. Analyses revealed that support from family and friends were each negatively correlated with posttraumatic cognitions, which in turn were positively associated with PTSD. Social support from a close other was not associated with posttraumatic cognitions. No significant differences in the model were found between trauma groups. Findings identify which relationships are likely to influence posttraumatic cognitions and are discussed with regard to interpersonal processes in the development and maintenance of PTSD.     

Sex differences in biopsychosocial correlates of binge eating disorder: a study of treatment-seeking obese adults in primary care setting

Objective

Although community-based studies suggest equivalent levels of physical and psychological impairment by binge eating disorder (BED) in men and women, men with BED are still underrepresented in clinical studies. This study aimed to provide a comprehensive analysis of sex differences in biopsychosocial correlates of treatment-seeking obese patients with BED in primary care.

Method

One hundred-ninety obese adults (26% men) were recruited in primary care settings for a treatment study for obesity and BED.

Results

Very few significant sex differences were found in the developmental history and in current levels of eating disorder features, as well as psychosocial factors. Women reported significantly earlier age at onset of overweight and dieting and greater frequency of dieting. Men reported more frequent strenuous exercise. Men were more likely than women to meet criteria for metabolic syndrome; men were more likely to show clinically elevated levels of triglycerides, blood pressure, and fasting glucose levels.

Conclusion

Despite few sex differences in behavioral and psychosocial factors, metabolic problems associated with obesity were more common among treatment-seeking obese men with BED than women. The findings highlight the importance of including men in clinical studies of BED and active screening of BED in obese men at primary care settings.     

Lifetime history of traumatic events in a young adult Mexican American sample: Relation to substance dependence,affective disorder,acculturation stress,and PTSD

Mexican Americans comprise one of the most rapidly growing populations in the United States, and within this population, trauma and post-traumatic stress disorder (PTSD) are associated with physical and mental health problems. Therefore, efforts to delineate factors that may uniquely contribute to increased likelihood of trauma, PTSD, and substance use disorders over the lifetime in Mexican Americans are important to address health disparities and to develop treatment and prevention programs. Six hundred fourteen young adults (age 18–30 yrs) of Mexican American heritage, largely second generation, were recruited from the community and assessed with the Semi-Structured Assessment for the Genetics of Alcoholism and an acculturation stress scale. More males (51.2%) reported experiencing traumas than females (41.1%), however, a larger proportion of females received a PTSD diagnosis (15%) than males (8%). Alcohol dependence and affective disorders, but not anxiety disorders, antisocial disorders, nicotine, marijuana, or stimulant dependence, were significantly comorbid with PTSD. Endorsing higher levels of acculturation stress was also significantly associated with both trauma exposure and a diagnosis of PTSD. Logistic regression revealed that female gender, having an affective disorder, alcohol dependence, higher levels of acculturation stress, and lower levels of education were all predictors of PTSD status. Additionally, alcohol dependence generally occurred after the PTSD diagnosis in early adulthood in this high-risk population. These studies suggest that treatment and prevention efforts should particularly focus on young adult second generation Mexican American women with higher levels of acculturation stress, who may be at higher risk for PTSD, affective disorder, and alcohol dependence following trauma exposure.     

Pain interference and incident mood,anxiety, and substance-use disorders: Findings from a representative sample of men and women in the general population

To examine gender differences in the longitudinal relationship between past-month pain interference and incident mood, anxiety, and substance-use disorders, chi-square tests and binomial logistic regression analyses were performed on data obtained from the National Epidemiologic Survey on Alcohol and Related Conditions from 34,465 adult respondents (47.9% men; 52.1% women) who completed waves 1 (2000–2001) and 2 (2004–2005) data collection. Models were adjusted for potentially confounding factors (i.e., age, race, marital status, educational level, employment, household income, number of stressful life events, number of general medical conditions, and wave-1 psychopathology). Respondents were categorized at wave 1 according to their past-month level of pain interference (i.e., no or low pain interference, moderate pain interference, severe pain interference). Moderate and severe pain interference (as compared to no or low pain interference) in male and female respondents was associated with the incidence of several psychiatric disorders. A stronger relationship was observed in male respondents as compared to female ones between past-month moderate pain interference and a new onset of any mood disorder (OR = 1.57, p = 0.03) and major depressive disorder (OR = 1.60, p = 0.03), and between past-month severe pain interference and a new onset of alcohol abuse or dependence (OR = 1.69, p = 0.045) and nicotine dependence (OR = 1.48, p = 0.04). These findings suggest that providers should consider screening patients with past-month moderate or severe pain interference for mood, anxiety, and substance-use problems and monitor the possible development of subsequent comorbid psychiatric disorders.     

Habitual sleep patterns and the distribution of body mass index: cross-sectional findings among Swedish men and women

Objective

To compare distributions of body mass index (BMI) between individuals with different habitual sleep patterns.

Methods

We performed cross-sectional analyses of 40,197 Swedish adults (64% women), who reported sleep duration and quality, weight, height, and possible confounding factors in 1997. Using quantile regression, we estimated associations between sleep patterns and selected percentiles of the distribution of BMI.

Results

While the medians were similar, larger adjusted values of BMI were estimated in the upper part of the distribution among men and women with short sleep (≤5 h) compared with medium-length sleep (6–8 h). For example, in men, the 90th percentile of BMI was 0.80 kg/m² (95% confidence interval: 0.17–1.43 kg/m²) higher among short sleepers. In women, long sleepers (≥9 h) also showed larger values in the upper part of the BMI distribution; the 90th percentile was 1.23 kg/m² (0.42–2.04 kg/m²) higher than in medium-length sleepers. In male long sleepers, smaller values were estimated in the lower part of the BMI distribution; the 10th percentile was 0.84 kg/m² lower (0.35–1.32 kg/m²) than in medium-length sleepers. The 90th percentile of BMI in women with poor-quality compared with good-quality sleep was larger by 0.82 kg/m² (0.47–1.16 kg/m²); the 10th percentile was smaller by 0.17 kg/m² (0.02–0.32 kg/m²).

Conclusions

Short, long or poor-quality sleepers showed larger, or smaller, values at the tails of the BMI distribution, but similar medians. Hence, unfavorable sleep patterns and BMI were associated only in a subset of this study population.     

Malingering of PTSD: forensic and diagnostic considerations, characteristics of malingerers and clinical presentations

OBJECTIVE: This paper aims to study the detection of individuals malingering posttraumatic stress disorder (PTSD) in criminal and civil situations. METHOD: A brief history of PTSD and its rise to prominence in legal circles are discussed. The characteristics of individuals who malinger and particularly those who fake PTSD are discussed. Diagnostic dilemmas inherent to the condition, such as the definition of a traumatic exposure, what constitutes a PTSD flashback and the potential for normal symptom exaggeration, are explored. RESULTS: The typical presentation of malingered symptoms is presented to help clinicians detect commonly seen malingering patterns. Suggestions for interview techniques, Minnesota Multiphasic Personality Inventory test values and sources of collateral information to help detect malingering are reviewed. CONCLUSION: The paper concludes with a review of the typical presentations of malingered PTSD symptoms and a reminder that physicians need to distinguish legitimate symptoms from faked or embellished presentations.     

Predictors of loneliness among older women and men in Sweden: A national longitudinal study

Objectives: Longitudinal research on loneliness in old age has rarely considered loneliness separately for men and women, despite gender differences in life experiences. The objective of this study was to examine the extent to which older women and men (70+) report feelings of loneliness with a focus on: (a) changes in reported loneliness as people age, and (b) which factors predict loneliness.

Method: Data from the 2004 and 2011 waves of SWEOLD, a longitudinal national survey, was used (n = 587). The prediction of loneliness in 2011 by variables measured in 2004 and 2004–2011 variable change scores was examined in three logistic regression models: total sample, women and men. Variables in the models included: gender, age, education, mobility problems, depression, widowhood and social contacts.

Results: Older people moved into and out of frequent loneliness over time, although there was a general increase in loneliness with age. Loneliness at baseline, depression increment and recent widowhood were significant predictors of loneliness in all three multivariable models. Widowhood, depression, mobility problems and mobility reduction predicted loneliness uniquely in the model for women; while low level of social contacts and social contact reduction predicted loneliness uniquely in the model for men.

Conclusion: This study challenges the notion that feelings of loneliness in old age are stable. It also identifies important gender differences in prevalence and predictors of loneliness. Knowledge about such differences is crucial for the development of effective policy and interventions to combat loneliness in later life.     

The interactive effects of elevated mid-afternoon cortisol and trauma history on PTSD symptoms in children: A preliminary study

Given the alarming frequency and severity of trauma exposure among children, identifying contextual and biologic factors that increase risk for symptomatic responses to trauma is an essential step toward preventing psychopathology. Basal functioning of the hypothalamic pituitary adrenal axis was evaluated to determine its role in relations between trauma exposure and PTSD symptoms among 66 children (M age = 10.7 years). Exposure to recent trauma (within the past year), previously experienced trauma (more than 1 year ago), and basal mid-afternoon cortisol levels were each positively related to PTSD symptoms. Further, these factors interacted in an additive manner to account for a significant proportion of the variance in PTSD symptoms. Implications for the early identification of children at risk for symptomatic responses to trauma are discussed.     

Trauma and posttraumatic stress disorder in Japan: Results from the World Mental Health Japan Survey

The purpose of the study was to report the prevalence of trauma exposure and PTSD, conditional risk of PTSD associated with each trauma exposure in the community population in Japan. An interview survey was conducted of a random sample of adult residents in 11 communities of Japan. Among 4134 respondents (response rate, 55%), data from those who completed the part 2 interview (n = 1682) were analyzed with a weight for this subsample. Lifetime experiences of 27 trauma events and PTSD were assessed using the WHO-Composite International Diagnostic Interview version 3.0. Sixty percent of the part 2 sample reported exposure to at least one lifetime traumatic event. Lifetime and 12-month PTSD prevalences were 1.3% and 0.7%, respectively. Percentage of all months lived with PTSD in the population was predominantly accounted for by physical/sexual assaults and having a child with serious illness, and unexpected death of loved one. Ten percent of respondents reported “private events”, for which respondents did not have to describe the content, which accounted for 19% of months with PTSD. The lower prevalence of PTSD in Japan seems attributable to lower conditional risks of PTSD following these events, as well as different distributions of the events. The greater impact of events that occurred to loved ones rather than to oneself and “private events” on PTSD in Japan warrants further research of cross-cultural assessment of trauma exposure and cultural heterogeneity in the trauma-PTSD relationship.     

Psychiatric comorbidity predicts sleep disturbances among adolescent earthquake survivors: a 10-year cohort study

ObjectiveTo examine the prevalence of sleep disturbances 10 years after Wenchuan earthquake, and to explore whether comorbid post-traumatic stress disorder (PTSD) and depressive symptoms could predict sleep disturbances and whether such effects were modified by gender.MethodsParticipants were 1357 adolescents in the Wenchuan Earthquake Adolescent Health Cohort Study (WEAHC). 799 of the participants completed the followed-up survey 10 years after the earthquake. At 12-month post-earthquake (T_12m), a battery of standardized measures were used to assess individual earthquake exposure, sleep disturbances (insomnia symptoms and poor sleep quality), PTSD, and depressive symptoms. At 10 years post-earthquake (T_10y), those survivors reported their sleep disturbances via an online survey. Data were analyzed using binary logistic regression.ResultsThe prevalence of insomnia (14.3%) and of poor sleep quality (19.8%) at T_10y decreased when compared with it at T_12m. After controlling for covariates, it is revealed that depression-only and comorbidity groups at T_12m predicted sleep disturbances at T_10y among the whole sample and males. As for females, who have depression-only and comorbidity were more likely to develop insomnia symptoms but not poor sleep quality.ConclusionsSleep disturbances remained highly prevalent among survivors even 10 years after the earthquake. Depression-only and comorbidity groups were related to higher risks of sleep disturbances, especially for males. Assessments and interventions targeting both depressive symptoms and comorbid PTSD to reduce sleep disturbances after a deadly disaster are warranted.     

Eating disorders and substance abuse in Canadian men and women: a national study

The objective of this study was to examine the co-morbidity between eating disorders and substance use in a large nationally representative sample of Canadian women and men while including varied measures of substance consumption and a wide range of substance classes. The research was based on secondary analyses of data collected, using multistage stratified probability sampling, by Statistics Canada in the Mental Health and Well-being cycle 1.2 of the Canadian Community Health Survey (CCHS). Data were collected mostly in face to face interviews using the Computer Assisted Personal Interviewing method. Data included the Eating Attitude Test (EAT-26), and modules of the short form of the Composite International Diagnostic Interview (CIDI-SF) to assess alcohol and drug use, dependence and interference. Alcohol interference and amphetamine use were associated with the risk for an eating disorder in both women and men. In the women sample only, risk for an eating disorder was associated with illicit drug use, dependence and interference, as well as with the number of substance classes used. The study findings support the importance of developing assessment instruments and treatment strategies that address the co-occurrence of eating disorders and substance use for both women and men.
