The associations of subjective appraisal of birth pain and provider-patient communication with postpartum-onset PTSD.

Childbirth-related PTSD is generally believed to result from multiple factors, including negative objective and subjective experiences and patient predisposing factors. There is conflicting evidence regarding whether severe childbirth pain affects development of PTSD. We hypothesize that a woman's retrospective subjective appraisal of birth pain is a greater predictor of postpartum-onset PTSD than medically documented measures of pain, and that a positive subjective experience communicating with medical providers during labor also reduces risk for postpartum-onset PTSD. A sample of 112 women, who screened positive for psychopathology within a year postpartum, were interviewed probing for their subjective labor experiences. Interviews were coded for subjective labor pain perception and quality of provider communication. Regression analyses tested associations between subjective labor pain perception and quality of provider communication with postpartum PTSD. Pain scores recorded during labor were not significantly associated to probable PTSD at any recorded time point up to 12 months postpartum. Positive perception of birth pain was associated with reduced risk of probable PTSD at 6 weeks postpartum (aOR = 0.34, p = 0.03). Positive provider communication was associated with reduced risk of probable PTSD at 6 months (aOR = 0.29, p = 0.02) and 12 months (aOR = 0.2, p = 0.03) postpartum. Pain recorded during childbirth is not necessarily a negative experience leading to trauma. For some women, even severe pain may be seen positively, and lacks traumatizing elements. Interventions to positively shift women's childbirth pain appraisal and educate medical workforce in patient-provider communication may reduce rates of postpartum PTSD.

Combat, Posttraumatic Stress Disorder, and Smoking Trajectory in a Cohort of Male Australian Army Vietnam Veterans.

Background: Whether trauma exposure itself or consequent posttraumatic stress disorder (PTSD) is primarily responsible for smoking and failure to quit remains unclear. Methods: A cohort of male Australian Vietnam veterans (N = 388) was interviewed twice, 22 and 36 years after their return to Australia using standardized psychiatric diagnostic and health interviews and assessment of combat exposure. The smoking trajectory over time revealed a spectrum of outcomes (never smoked, early quitters, late quitters, and continuing smokers). Analysis used multivariate statistics to assess the relative contributions of combat trauma exposure and PTSD while controlling for potential confounders. Results: The trajectory of smoking over time revealed that 21.9% of veterans had never smoked, 45.1% had quit smoking by the time of wave 1, 16.2% were current smokers at wave 1 who had quit by the time of wave 2, 2.8% were late adopters who were current smokers, and 13.9% were continuing smokers. Smoking was associated in single-predictor models with demographics, intelligence, combat exposure, PTSD symptom clusters and diagnosis, and alcohol disorders. Multivariate analysis revealed that PTSD, combat, and intelligence were related to the smoking spectrum but, after adding demographics and other Axis I psychiatric diagnoses, only combat remained significant. No PTSD symptom cluster uniquely predicted smoking status. Conclusions: The results suggest that trauma exposure in the form of military combat may be a more robust predictor of smoking status over time than PTSD. It may be stress itself, rather than poststress disorder, that is more germane to smoking and failure to quit. Implications: Exposure to traumatic stress and development of PTSD have been implicated separately in the maintenance of smoking. This longitudinal cohort study of smoking in war veterans up to three decades postwar enabled evaluation of traumatic stress exposure in combat and the course of PTSD in smoking and quitting while controlling for intelligence, background disadvantage, and other psychiatric conditions. Combat rather than PTSD emerged as more significant to smoking status, suggesting that it may be the traumatic stress itself rather than the development of a poststress disorder that is more germane to smoking in war veterans.
