About this study

The purpose of this research is 1) to investigate the role of the sympathetic nervous system and cardiac-vascular function in women with PTSD; and 2) to determine whether lifestyle modifications (exercise training and healthy eating) would be effective in reducing sympathetic activity, improving cardiovascular function, and improving psychiatric and quality of life outcomes in women with PTSD. It is hypothesized that (1) women with PTSD will have over-activation of the sympathetic nervous system and impaired cardiac-vascular function compared with women who are trauma free, and (2) lifestyle modifications can reduce sympathetic activity, improve cardiac-vascular function, and improve psychiatric symptoms and quality of life in women with PTSD.

Read the detailed description

This is a collaborative study between the Institute for Exercise and Environmental Medicine (IEEM; Texas Health Resources/University of Texas Southwestern medical Center) and VA North Texas Healthcare System (VANTHCS). The overall study was conceptualized and initiated by Dr. Qi Fu and her research team at the IEEM. IEEM researchers will be responsible for recruitment of non-veteran women without a diagnosis of PTSD, physiological assessments, and the lifestyle modification intervention. VANTHCS researchers will be responsible for recruitment of women veterans with PTSD and psychological assessments. The procedures taking place at VANTHCS (recruitment of women Veterans with PTSD and psychological assessments) will fall under a separate study (overseen by VANTCHS IRB and RDC) and will not include the procedures and intervention that will take place at the IEEM (which will be overseen by a separate IRB). Data will be shared between the sites per data sharing agreement. This clinical trials entry reflects the VANTHCS study. Outcome measures gathered by the IEEM research team are included in this entry due to the data sharing agreement.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Exercise training and healthy eating (overseen by IEEM research team)Behavioural

    Exercise Training: A "personalized" training program will be developed for participants. Based on maximal steady state heart rate and resting heart rate, three training zones (recovery, base pace, and maximal steady state) will be determined. The target heart rate for each training zone will be set for each patient. The majority of training sessions during the early phase of the program will be prescribed as "base pace" with target heart rate equivalent to about 75% of maximal. Initially, patients will train 3 times per week for 20-30 minutes per session by walking, jogging or swimming. As the patients become relatively fit, the duration of the base training sessions will be prolonged, and subsequently sessions of increased intensity (i.e., maximal steady state) will be added.

    Healthy Eating: Participants will be provided with dietary advice consistent with the American Heart Association guidelines (D.A.S.H. diet eating plan).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Muscle Sympathetic Nerve Activity (MSNA; Data collected by IEEM)

    Muscle sympathetic nerve activity will be measured using microneurography at the peroneal nerve.

    Measured: +PTSD vs. -PTSD baseline comparison; Changes from baseline following 12-week intervention

  2. Clinician Administered Posttraumatic Stress Disorder Scale - 5 (CAPS-5; Data collected by VANTHCS)

    CAPS-5 is a 30-item structured interview that corresponds to the DSM-5 diagnosis for PTSD. The instrument is used to make a current or lifetime diagnosis of PTSD, as well as assess symptom severity. Total symptom severity scores range from 0 to 80. A higher score indicates greater symptom severity. Individual symptom severity scores range from 0 (absent) to 4 (extreme/incapacitating) and are based on symptom frequency and intensity.

    Measured: Changes from baseline following 12-week intervention

Secondary outcomes (9)
  1. PTSD Checklist for DSM-5 (PCL-5; Data collected by VANTHCS)

    Self-report measure of PTSD symptoms

    Measured: Changes from baseline through 12-week intervention

  2. Quick Inventory for Depressive Symptomatology-self report (QIDS- SR16; Data collected by VANTHCS)

    Self-report measure of depression symptom severity. Total scores range from 0-27. A higher score indicates greater symptom severity.

    Measured: Changes from baseline through 12-week intervention

  3. Concise Health Risk Tracking Scale - self-report module (CHRT; data collected by VANTHCS)

    The CHRT-SR is a 16-item self-report measure that assesses suicidal propensity and risk. All items are scored on a 5-point Likert scale ranging from "strongly disagree" (0) to "strongly agree" (4). The propensity score (items 1-13) assesses pessimism, helplessness, perceived lack of social support, and despair. The propensity score may range from 0 to 52, with higher scores showing higher levels of suicidal propensity. The risk score (items 14-16) assess thoughts and plans of killing oneself. The risk score may range from 0-12, with a higher score showing higher levels of suicidal thoughts.

    Measured: Changes from baseline through 12-week intervention

  4. Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF; data collected by VANTHCS)

    The Q-LES-Q-SF is a 16 item self-report measure that assesses perceived quality of life. All items are scored on a 5-point Likert scale ranging from "very poor" (1) to "very good" (5). raw total score is created by summing the first 14 items. The last two items are standalone items and not included in the total score. Raw total score ranges from 14-70. The raw total score is transformed into a percentage maximum possible score using the following formula: (raw total score - minimum score)/(maximum possible raw score-minimum score). Percentage maximum ranges from 0% to 100, with a lower percentage indicating worse perceived quality of life.

    Measured: Changes from baseline through 12-week intervention

  5. 36-Item Short Form Health Survey (SF-36; Data collected by IEEM)

    The SF-36 is a 36-item self-report measure of general health status. The measure includes multi-item scales to measure the following 8 dimensions: physical functioning; role limitations due to physical health problems; bodily pain; social functioning; general mental health; role limitations due to emotional problems; vitality, energy, or fatigue; and general health perceptions. All items are scored so that a higher score indicates a more favorable health state. The SF-36 produces two sets of scores: a profile of eight sections scores, and two summary scores (physical component scores [PCS] and mental component scores [MCS].

    Measured: +PTSD vs. -PTSD baseline comparison; Changes from baseline following 12-week intervention

  6. Endothelial function (data collected by IEEM)

    Measured using flow-mediated vasodilation

    Measured: +PTSD vs. -PTSD baseline comparison; Changes from baseline following 12-week intervention

  7. Arterial stiffness (Data collected by IEEM)

    Central and peripheral pulse wave velocity measured using arterial tonometry

    Measured: +PTSD vs. -PTSD baseline comparison; Changes from baseline following 12-week intervention

  8. Systolic and diastolic cardiac function (Data collected by IEEM)

    Measured using echocardiogram

    Measured: +PTSD vs. -PTSD baseline comparison; Changes from baseline following 12-week intervention

  9. Physical Fitness (Data collected by IEEM)

    Peak oxygen uptake (Douglas bag method) during submaximal and maximal treadmill test

    Measured: Changes from baseline following 12-week intervention
