Associations of Trauma Exposure and Posttraumatic Stress Symptoms With Venous Thromboembolism Over 22 Years in Women.

ABSTRACT: Trauma exposure and posttraumatic stress disorder (PTSD) have been linked to myocardial infarction and stroke in women, with biological and behavioral mechanisms implicated in underlying risk. The third most common cardiovascular illness, venous thromboembolism (VTE), is a specific health risk for women. Given previous associations with other cardiovascular diseases, we hypothesized that high levels of trauma and PTSD symptoms would be associated with higher risk of incident VTE in younger and middle-aged women.We used proportional hazards models to estimate hazard ratios (HRs) and 95% CIs for new-onset VTE (960 events) over 22 years in 49 296 women in the Nurses' Health Study II. Compared to no trauma exposure, both trauma exposure and PTSD symptoms were significantly associated with increased risk of developing VTE, adjusting for demographics, family history, and childhood adiposity. Women with the most PTSD symptoms exhibited the greatest risk elevation: trauma/6 to 7 symptoms: HR=2.42 (95% CI, 1.83-3.20); trauma/4 to 5 symptoms: HR=2.00 (95% CI, 1.55-2.59); trauma/1 to 3 symptoms: HR=1.44 (95% CI, 1.12-1.84); trauma/no symptoms: HR=1.72 (95% CI, 1.43-2.08). Results were similar, although attenuated, when adjusting for VTE-relevant medications, medical conditions, and health behaviors.Women with the highest PTSD symptom levels had nearly a 2-fold increased risk of VTE compared to women without trauma exposure in fully adjusted models. Trauma exposure alone was also associated with elevated VTE risk. Trauma and PTSD symptoms may be associated with a hypercoagulable state. Treatment providers should be aware that women with trauma exposure and PTSD symptoms may be vulnerable to VTE.

Project description:Posttraumatic stress disorder (PTSD) appears to increase obesity risk but the pathways by which PTSD leads to weight gain are not known. Identification of the links between PTSD and obesogenic eating behaviors is necessary to clarify this pathway and inform development of obesity prevention strategies in PTSD-affected populations.To determine whether women with PTSD symptoms are more likely to report food addiction, a measure of perceived dependence on food, than women without PTSD symptoms. Also, to determine whether age at PTSD symptom onset and type of trauma influence the PTSD-food addiction association.Cross-sectional analysis of 49,408 participants in the Nurses' Health Study II, a cohort comprising women nurses who were aged 25 to 42 years at the 1989 recruitment from 14 US states.The Nurses' Health Study II ascertained lifetime trauma exposure and PTSD symptoms in 2008 and current food addiction in 2009. Food addiction was defined as 3 or more clinically significant symptoms on a modified version of the Yale Food Addiction Scale. Confounder-adjusted prevalence ratios and 95% CIs were estimated using modified Poisson regression.Approximately 80% of the study sample reported some type of trauma exposure, with 66% of the trauma-exposed participants reporting at least 1 lifetime PTSD symptom. Eight percent of the cohort met the criteria for food addiction. The prevalence of food addiction increased with the number of lifetime PTSD symptoms, and women with the greatest number of PTSD symptoms (6-7 symptoms) had more than twice the prevalence of food addiction as women with neither PTSD symptoms nor trauma histories (prevalence ratio, 2.68; 95% CI, 2.41-2.97). Symptoms of PTSD were more strongly related to food addiction when symptom onset occurred at an earlier age. The PTSD-food addiction association did not differ substantially by trauma type.Symptoms of PTSD were associated with increased food addiction prevalence in this cohort of women. Strategies to reduce obesity associated with PTSD may require psychological and behavioral interventions that address dependence on food and/or use of food to cope with distress.

Project description:Chronic insomnia tends to "wax and wane" over lifetime. The presence of residual insomnia symptoms is common, especially among naturally remitted individuals. This study aims to examine the features of these residual symptoms and their potential association with future relapse. A population-based data set on the natural history of insomnia was used for this secondary analysis. Residual insomnia symptoms were investigated in those who had insomnia symptoms/syndrome at baseline and achieved full remission (according to predetermined diagnostic algorithm) within the following 1 year. Cox regressions were used to determine the hazard ratio (HR) of each residual symptom for predicting relapse in the next 4 years. The nature and severity of residual symptoms were examined with an extended version of the Insomnia Severity Index (ISI), which incorporates additional items on sleep quality and specific sleep-related daytime impairments (on daytime fatigue, cognitive functioning, mood, interpersonal relationship, and daily activities). In addition, the presence of depressive symptoms and medical conditions were controlled for in investigating risks of insomnia relapse. A total of 434 participants were included in this study (age ranges from 18 to 94; 65.9% female); 248 of them had relapsed within 4 years. The response rate ranged from 78% to 83%. The most frequently reported residual symptoms with at least moderate severity (ISI items ≥2 on 0-4 ISI item scale) were poor "Quality of sleep" (39.2 %), followed by "difficulty maintaining sleep" (DMS; 27%). The most common residual daytime impairments related to insomnia were fatigue (24.7 %), mood disturbances (23%) and cognitive disturbances (22.6%). After controlling for baseline insomnia and depression severity and concurrent physical diseases, impairments of cognition (HR = 1.46), poor quality of sleep (HR = 1.43), disturbed mood (HR = 1.39), being female (HR = 1.36), DMS (HR = 1.35), and fatigue (HR = 1.24) were significantly associated with insomnia relapse in the next 4 years. Moreover, residual poor sleep quality and daytime insomnia symptoms were independent of DMS in predicting relapse. Subgroup regressions according to sex showed that for male participants, residual cognition impairments (HR = 1.98) was the most significant predictors of future relapse, whereas residual DMS (HR = 1.46) significantly predicted relapse for women only. A wide range of residual symptoms exists in individuals with naturally remitted insomnia. Notably, residual DMS is the most common residual nighttime symptom and the only nighttime symptom associated with insomnia relapse. Additionally, perceived poor sleep quality and cognitive, mood, and somatic impairments attributed to sleep disturbances are also related to future relapse. Attention to these residual symptoms when initiating insomnia treatment is warranted to minimize future relapse.
