Abstract

The present meta-analysis systematically examined associations between physical health and posttraumatic stress disorder (PTSD)/PTSD symptoms (PTSS), as well as moderators of this relationship. Literature searches yielded 62 studies examining the impact of PTSD/PTSS on physical health-related quality of life (HR-QOL), general health symptoms, general medical conditions, musculoskeletal pain, cardio-respiratory (CR) symptoms, and gastrointestinal (GI) health. Sample-specific and methodological moderators were also examined. Results revealed significantly greater general health symptoms, general medical conditions, and poorer HR-QOL for PTSD and high PTSS individuals. PTSD/PTSS was also associated with greater frequency and severity of pain, CR, and GI complaints. Results of moderation analyses were mixed. However, consistent relationships emerged regarding PTSD assessment method, such that effect sizes were largest for self-reported PTSD/PTSS and all but one health outcome. Results highlight the need for prospective longitudinal examination of physical health shortly following trauma, and suggest variables to consider in the design of such studies.

Highlights

► We systematically examined the impact of PTSD and PTSD symptoms on physical health. ► The strongest relationship emerged between PTSD and general physical symptoms. ► Moderating variables of the PTSD-physical health relationship were identified.

Physical health outcomes influenced by PTSD

A multitude of individual psychological, behavioral, and biological factors (see Schnurr & Jankowski, 1999 and Pace & Heim, 2011 for reviews) as well as the interactions between these factors, serve as possible mechanisms through which PTSD may be associated with physical health. PTSD is characterized by a failure to physiologically adapt to stressors and reminders of stressors, such that the long-term activation of the stress pathways (i.e., sympathetic nervous system,

Sample moderators

Females report greater levels of PTSD than males (Tolin & Foa, 2006), and tend to report physical symptoms up to 50% more frequently than males independent of the presence of mental comorbidity (Kroenke & Spitzer, 1998). However, prior research has failed to find gender to be a significant moderator of the relationship between PTSD and physical health (Andreski et al., 1998, Kimerling et al., 2002, Ouimette et al., 2004, Wagner et al., 2000). Veteran status may also impact results; compared to

Selection of studies

Literature searches were conducted using PsycINFO, MEDLINE, and PILOTS databases.

Key search phrases included combinations of the following terms: PTSD, PTSS, physical health, somatic symptoms, cardiovascular, respiratory, cardio-respiratory, pulmonary, gastrointestinal, musculoskeletal pain, and HR-QOL. Additional studies were identified through the reference sections of relevant empirical and review articles. When necessary statistical information was omitted from an otherwise eligible

Weighted mean effect sizes

Sample and study characteristics of the 62 studies (118 independent effect sizes) are displayed in Table 1. Weighted effect sizes for each individual study are presented in Table 2, and Table 3 presents the overall weighted mean effect sizes for the 6 health outcomes. Examination of the Q statistics revealed that all health outcomes, with the exception of general medical conditions, were heterogeneous. Therefore, calculation of mean effect sizes was conducted with the random effects model for

Discussion

Results of the present meta-analysis support prior research by demonstrating that PTSD/PTSS were significantly related to each examined health outcome. These results expand prior research by providing an index of strength between PTSD/PTSS and physical health outcomes. More specifically, the largest effect size emerged for general health symptoms, followed by a moderate effect for medical conditions, and small effects for HR-QOL and GI health. CR health displayed the weakest effect.
