Sleep Quality and Reexperiencing Symptoms of PTSD Are Associated With Current Pain in US OEF/OIF/OND Veterans With and Without mTBIs

Pain, a debilitating condition, is frequently reported by U.S. veterans returning from Afghanistan and Iraq. This study investigated how commonly reported clinical factors were associated with pain and whether these associations differed for individuals with a history of chronic pain. From the Boston metropolitan area, 171 veterans enrolled in the Veterans Affairs Center of Excellence were assessed for current posttraumatic stress disorder (PTSD) symptom severity, current mood and anxiety diagnoses, lifetime traumatic brain injury, combat experiences, sleep quality, and alcohol use. Hierarchical regression models were used to determine the association of these conditions with current pain. Average pain for the previous 30 days, assessed with the McGill Pain Questionnaire, was 30.07 out of 100 (SD = 25.43). Sleep quality, PTSD symptom severity, and alcohol use were significantly associated with pain (R-2 = .24), as were reexperiencing symptoms of PTSD (R-2 = .25). For participants with a history of chronic pain (n = 65), only PTSD symptoms were associated with pain (R-2 = .19). Current pain severity was associated with increased PTSD severity (notably, reexperiencing symptoms), poor sleep quality, and increased alcohol use. These data support the hypothesis that PTSD symptoms influence pain, but suggest that problems with sleep and alcohol use may exacerbate the relationship. Resumen SUENO, TEPT Y DOLOR EN VETERANOS El dolor, una condicion debilitante, es frecuentemente reportado por veteranos norteamericanos que vuelven de Afganistan e Iraq. Este estudio investigo como los factores clinicos comunmente reportados se asociaron con dolor y si estas asociaciones difieren en los individuos con historia de dolor cronico. Desde el area metropolitana de Boston, 171 veteranos enrolados en el Centro de Excelencia de Asuntos Veteranos fueron evaluados en la severidad de los sintomas de TEPT, diagnosticos de estado de animo y ansiedad actuales, LCT (lesion cerebral traumatica) a lo largo de la vida, experiencias de combate, calidad del sueno y consumo de alcohol. Modelos de regresion jerarquica fueron usados para determinar la asociacion de estas condiciones con el dolor actual. El dolor promedio para los 30 dias previos, evaluados con el cuestionario de dolor McGill, fue 30.07 de 100 (DE = 25.43). La calidad del sueno, severidad de los sintomas de TEPT, y uso de alcohol se asociaron significativamente con dolor (R2 = .24), asi como tambien los sintomas de re-experimentacion de TEPT (R2 = .25). Para los participantes con historia de dolor cronico (n = 67), solo los sintomas de TEPT se asociaron con dolor (R2 = .19). La severidad del dolor actual se asocio con mayor severidad de TEPT (mayormente, sintomas de re-experimentacion), mala calidad de sueno, y aumento del consumo de alcohol. Estos datos apoyan la idea que los sintomas de TEPT influyen sobre el dolor, pero sugieren que los problemas del sueno y consumo de alcohol pueden exacerbar esta asociacion.
