Dimensions of posttraumatic stress disorder and menopause-related health in midlife women veterans.

Objective: Posttraumatic stress disorder (PTSD) has been linked with menopause symptoms (eg, vasomotor, urinary) and their sequelae (eg, sexual difficulties). However, PTSD is a heterogeneous disorder, and less is known about which aspects may be most associated with menopause-related health.

Methods: Using confirmatory factor analyses, we evaluated five structural models of PTSD symptoms in 208 predominately postmenopausal women veterans (aged 45-64 years). We investigated associations between PTSD-operationalized as a probable diagnosis and symptom dimensions of the best-fitting model-and common menopause-related health concerns, including (1) vasomotor, urinary, and vaginal symptoms; (2) vasomotor symptom interference; and (3) sexual functioning.

Results: A six-factor anhedonia model-comprising re-experiencing, avoidance, negative affect, anhedonia, anxious arousal, and dysphoric arousal-provided optimal fit. Both probable PTSD and greater symptoms across all dimensions were linked with presence of urinary and vasomotor, but not vaginal, symptoms. Comparing dimensions revealed that negative affect and dysphoric arousal were particularly associated with urinary symptoms, whereas dysphoric arousal was the factor most strongly related to vasomotor symptom interference. Associations between PTSD and sexual dysfunction were mixed; whereas there was no relation with probable diagnosis, all dimensions were linked with adverse sexual sequelae.

Conclusions: PTSD-considered categorically and dimensionally-was relevant to menopause-related health in midlife women veterans. Further, symptoms of negative affect and dysphoric arousal were particularly related to urinary and vasomotor symptoms. These specific symptoms may drive associations between PTSD and these aspects of menopause-related health. Clinical interventions targeting these symptoms may promote midlife women's health.
