Adult health status of women HMO members with posttraumatic stress disorder symptoms

Abstract

Posttraumatic stress disorder (PTSD) is associated with high numbers of self-reported physical symptoms and functional disability in clinical samples, but little is known about the magnitude of these associations in population samples and using actual physician-coded diagnoses. We administered a 22-page survey to 1225 female HMO enrollees randomly selected from the current membership of a large, staff model HMO in Seattle, Washington. Using the PTSD Checklist (internally validated against a subset of clinical interviews) we compared women with low, moderate, and high scores with respect to differences in self-reported physical health status, functional disability (36-item short form health survey), numbers and types of self-reported health risk behaviors, common physical symptoms, and physician-coded ICD-9 diagnoses. Compared to women with low PTSD symptom severity, those with moderate or high severity reported significantly higher functional disability ( P<.001), rates of abuse and neglect ( P<.01 to P<.001), health risk behavior scores ( P<0.05), as well as higher mean numbers of common physical symptoms ( P<.05). Compared to women with low PTSD symptom severity those with moderate or high severity had significantly higher adjusted odds ratios for aversive physical symptoms (range, 1.7-10.1). The mean number of physician-coded ICD-9 diagnoses was also significantly higher in the both the moderate and high severity groups. Among female HMO members, PTSD symptoms are associated with a wide range of both self-reported and physician-coded adverse physical health outcomes.
