摘要
Background: It is well-established that adults with elevated psychiatric symptoms or a psychiatric disorder (e.g. depression) engage in lower amounts of physical activity (PA) compared to adults with fewer symptoms/no diagnosis. However, less is known about the association between psychiatric symptoms and PA behaviour in trauma-exposed adults. Most prior investigations have focused on independent associations between overall depression or posttraumatic stress disorder (PTSD) symptoms in relation to PA and have neglected specific symptom domains (e.g. anhedonia). Therefore, we conducted secondary analyses on a parent dataset to examine whether PTSD symptom severity moderates the association between anhedonia and PA volume.Methods: Trauma-exposed adults (N = 107, 61% women, M +/- SD age = 28 +/- 9 y 54% White) completed questionnaires assessing demographic information, anhedonia, PTSD symptom severity (overall and symptom clusters), and PA volume (total MET-min/week). Main effects and interactions between anhedonia and PTSD symptom severity in relation to PA volume were examined with robust linear regression models.Results: We observed a significant anhedonia x PTSD symptom severity interaction. An inverse association between anhedonia and PA volume was observed among adults with lower-to-moderate PTSD symptom severity, and a positive association between anhedonia and PA volume was observed among adults with higher PTSD symptom severity. Significant anhedonia x PTSD symptom severity interactions for avoidance (Cluster C) and negative alterations in arousal/reactivity (Cluster E) symptoms were also observed, with associations in the same direction as the overall PTSD symptom severity model.Conclusion: These preliminary findings suggest that co-occurring anhedonia and PTSD symptom severity profiles interact to influence PA volume in trauma-exposed adults. Future research is needed to understand why trauma-exposed adults with greater co-occurring anhedonia and PTSD symptom severity profiles reported engaging in higher levels of PA compared to those with lower symptom severity profiles. Such knowledge could help healthcare practitioners tailor treatment plans to incorporate or adjust PA prescriptions. Antecedentes: Esta bien establecido que los adultos con s & iacute;ntomas psiqui & aacute;tricos elevados o un trastorno psiqui & aacute;trico (ej., depresi & oacute;n) realizan menos actividad f & iacute;sica (AF) en comparaci & oacute;n con adultos con menos s & iacute;ntomas o sin diagn & oacute;stico. Sin embargo, se sabe menos acerca de la asociaci & oacute;n entre s & iacute;ntomas psiqui & aacute;tricos y conducta de AF en adultos expuestos a trauma. La mayor & iacute;a de las investigaciones anteriores se han centrado en las asociaciones independientes entre los s & iacute;ntomas generales de depresi & oacute;n o de trastorno de estr & eacute;s postraum & aacute;tico (TEPT) en relaci & oacute;n con la AF y han descuidado dominios de s & iacute;ntomas espec & iacute;ficos (ej., anhedonia). Por lo tanto, realizamos an & aacute;lisis secundarios en una base de datos principal para examinar si la gravedad de los s & iacute;ntomas de TEPT modera la asociaci & oacute;n entre anhedonia y el volumen de AF.M & eacute;todo: Los adultos expuestos a trauma (N = 107, 61% mujeres, M +/- DE edad = 28 +/- 9 y 54% cauc & aacute;sicos) completaron cuestionarios que evaluaban informaci & oacute;n demogr & aacute;fica, anhedonia, gravedad de los s & iacute;ntomas de TEPT (en general y por grupos de s & iacute;ntomas), y el volumen de AF (MET-min total/semana). Se examinaron los efectos principales y la interacci & oacute;n entre anhedonia y gravedad de los s & iacute;ntomas de TEPT en relaci & oacute;n con el volumen de AF mediante modelos de regresi & oacute;n lineal robustos.Resultados: Observamos una interacci & oacute;n significativa entre la anhedonia y la gravedad de los s & iacute;ntomas de TEPT. Se observ & oacute; una asociaci & oacute;n inversa entre anhedonia y el volumen de AF en los adultos con gravedad de s & iacute;ntomas de TEPT de baja a moderada, y se observ & oacute; una asociaci & oacute;n positiva entre la anhedonia y el volumen de AF en adultos con s & iacute;ntomas de TEPT m & aacute;s graves. Tambi & eacute;n se observaron interacciones significativas entre anhedonia y la gravedad de los s & iacute;ntomas de TEPT para los s & iacute;ntomas de evitaci & oacute;n (grupo C) y tambi & eacute;n se observaron alteraciones negativas en los s & iacute;ntomas de activaci & oacute;n/reactividad (grupo E), con asociaciones en la misma direcci & oacute;n que el modelo general de gravedad de los s & iacute;ntomas de TEPT.Conclusi & oacute;n: Estos hallazgos preliminares sugieren que la co-ocurrencia de anhedonia y perfiles de gravedad de los s & iacute;ntomas de TEPT interact & uacute;an para influir en el volumen de AF en adultos expuestos a trauma. Se necesitan investigaciones futuras para comprender por qu & eacute; los adultos expuestos a trauma con perfiles de gravedad de s & iacute;ntomas de TEPT mayores y co-ocurrencia con anhedonia reportaron participar en niveles m & aacute;s altos de AF en comparaci & oacute;n con aquellos con perfiles de gravedad de s & iacute;ntomas mas bajos. Esta informaci & oacute;n podr & iacute;a ayudar a los m & eacute;dicos generales a adecuar los planes de tratamiento para incorporar o adaptar la prescripci & oacute;n de AF.
