Disrupted Rhythmicity and Vegetative Functions Relate to PTSD and Gender in Earthquake Survivors

Abstract

Background: Increasing evidence indicates that survivors to traumatic events may show disruption of sleep pattern, eating and sexual behaviors, and somatic symptoms suggestive of alterations of biorhythmicity and vegetative functions. Therefore, the aim of this study was to investigate these possible alterations in a sample of survivors in the aftermath of earthquake exposure, with particular attention to gender differences and impact of post-traumatic stress disorder (PTSD). Methods: High school senior students, who had been exposed to the 2009 L'Aquila earthquake, were enrolled 21 months after the traumatic event and evaluated by the Trauma and Loss Spectrum Self-Report to investigate PTSD rates and by a domain of the Mood Spectrum Self-Report–Lifetime Version (MOODS-SR), to explore alterations in circadian/seasonal rhythms and vegetative functions. Results: The rates of endorsement of MOODS-SR rhythmicity and vegetative functions domain and subdomain scores were significantly higher in survivors with PTSD with respect to those without it. Among all earthquake survivors, women reported higher scores than men on the rhythmicity and vegetative functions domain and subdomain scores, except for the rhythmicity and sexual functions ones. Female survivors without PTSD showed significantly higher scores than men in the rhythmicity and vegetative functions total scores and the sleep and weight and appetite subdomains. Potentially traumatic events burden predicted rhythmicity and vegetative functions impairment, with a moderation effect of re-experiencing symptoms. Conclusions: We report impairments in rhythmicity, sleep, eating, and sexual and somatic health in survivors to a massive earthquake, particularly among subjects with PTSD and higher re-experiencing symptoms, with specific gender-related differences. Evaluating symptoms of impaired rhythmicity and vegetative functions seems essential for a more accurate assessment and clinical management of survivors to a mass trauma.

Post-Traumatic Stress Reactions in Caregivers of Children and Adolescents/Young Adults with Severe Diseases: A Systematic Review of Risk and Protective Factors

“…Moreover, while struggling with their difficulties in dealing with stress, caregivers often have a reduced access to support and resources [ 32 , 33 ]. Furthermore, PTSD has been positively associated to an increased risk of other psychopathological conditions and substance abuse, leading to a well-being impairment [ 34 , 35 , 36 ]. In this line, increasing evidence suggests that PTSD or PTSS could be associated to the onset of depression, suicidal behavior, anxiety, sleep problems, and other conditions in cares that worse their quality of life [ 1 , 2 , 4 , 7 , 9 ].…”

Validation of the Spanish Version of the Trauma and Loss Spectrum Self-Report (TALS-SR): A Study on Healthcare Workers Facing the COVID-19 Pandemic

“…This spectrum-conceptualized instrument has appeared to be useful for a variety of research purpose but also clinical ones, such as accurate psychopathological characterization and earlier identification of even subthreshold cases, treatment selection, assessment of lifetime longitudinal psychopathological trajectories and treatment outcomes, and clinical follow-ups. 13 The TALS-SR has been, in fact, adopted across several studies including not only clinical populations, such as subjects with PTSD, bipolar disorder, borderline personality disorder, prolonged grief disorder, [15][16][17] but also in the general population exposed to mass trauma, 18 rescuers and healthcare workers, 19,20 these latter also in the framework of the COVID-19 pandemic. 21 Much evidence of adverse psychological outcomes related to the COVID-19 pandemic have been reported since the infectious outbreak and the TALS-SR have been widely used as a spectrum instrument adopted to assess post-traumatic stress spectrum symptomatology.…”
