Development of a Tailored Behavioral Weight Loss Program for Veterans With PTSD (MOVE!+UP): A Mixed-Methods Uncontrolled Iterative Pilot Study

Posttraumatic Stress Disorder and Weight Loss in Male and Female Active-duty Service Members: A Weight Management Study

BACKGROUND

Overweight and obesity are critical public health concerns with relevance to U.S. military personnel, as active duty service members must meet physical fitness and body composition standards. Biological sex and posttraumatic stress disorder (PTSD) diagnosis may affect service members' weight management efforts, but it is unclear what contribution each of these factors independently or in combination have on weight loss.

METHOD

Addressing this gap in knowledge, the current study used multilevel models to examine the effects of sex and self-reported PTSD diagnosis on change in weight of active duty Navy service members (n = 178, 61% female, 24% PTSD) over the course of and after a behavioral weight management intervention.

RESULTS

On average, participants' weights decreased significantly during the intervention (P < .001), and there was a significant sex-by-PTSD interaction effect such that male participants without a self-reported PTSD diagnosis and female participants with a self-reported PTSD diagnosis lost significantly more weight during the intervention than their counterparts (P = .015). The main effects of sex and self-reported PTSD diagnosis on weight change during the intervention were nonsignificant (P's ≥ .24). While weight remained stable on average during the follow-up period (P = .28), female sex marginally predicted weight loss during the follow-up period (P = .07), whereas self-reported PTSD diagnosis and the sex-by-PTSD interaction were not significant (P's ≥ .16).

CONCLUSIONS

These results highlight the importance of considering both sex and PTSD diagnosis as factors that together may influence the efficacy of behavioral weight management programs for active duty service members.

Virtual Coach-Guided Online Acceptance and Commitment Therapy for Chronic Pain: Pilot Feasibility Randomized Controlled Trial

BACKGROUND

Veterans are disproportionately affected by chronic pain, with high rates of pain diagnoses (47%-56%) and a 40% higher rate of prevalence of severe pain than nonveterans. This is often accompanied by negative functional outcomes and higher mortality. Combined with research suggesting medical treatments for chronic pain are often insufficient, there is an urgent need for nonmedical pain self-management programs. An interactive online platform to deliver an efficacious treatment for chronic pain such as acceptance and commitment therapy (ACT) could be a valuable option to assist veterans with pain care at home.

OBJECTIVE

This study aims to evaluate the virtual coach-guided Veteran ACT for Chronic Pain (VACT-CP) online program compared to a waitlist and treatment as usual (WL+TAU) control group through a small pilot feasibility randomized controlled trial. The primary aim was to evaluate the feasibility and acceptability of VACT-CP and study procedures, such as ease of recruitment, treatment receptivity, attrition and retention, sustained participation, system usability, and assessment of trial procedures. Secondary aims explored differences in the VACT-CP and WL+TAU groups on pre- and posttest (week 7) outcome measures for pain, mental health, functioning, and ACT processes.

METHODS

Veterans with chronic pain were recruited and randomized to either the VACT-CP (n=20) or the WL+TAU (n=22) group in a parallel group trial design. Self-report surveys were administered to participants at baseline (week 0), at the intervention midpoint (week 3), immediately after the intervention (week 7), and at the 1-month follow-up (week 11). We used Wilcoxon signed rank tests with the intention-to-treat sample to describe changes in secondary outcomes from pre- to postintervention within each group.

RESULTS

Study procedures showed good feasibility related to recruitment, enrollment, randomization, and study completion rates. Participants reported that VACT-CP was easy to use (System Usability Scale: mean 79.6, SD 12.8; median 82.5, IQR 70-87.5); they completed an average of 5 of the 7 total VACT-CP modules with high postintervention satisfaction rates. Qualitative feedback suggested a positive response to program usability, content tailoring, veteran centeredness, and perceived impact on pain management. Although the pilot feasibility trial was not powered to detect differences in clinical outcomes and significant findings should be interpreted with caution, the VACT-CP group experienced significant increases in chronic pain acceptance (P<.001) and decreases in depressive symptoms (P=.03).

CONCLUSIONS

VACT-CP showed encouraging evidence of feasibility, usability, and acceptance, while also providing promising initial results in improving a key process in ACT for chronic pain-chronic pain acceptance-after online program use. A full-scale efficacy trial is needed to assess changes in clinical outcomes.

Insomnia, Short Sleep, and Their Treatments: Review of Their Associations with Weight

PURPOSE OF REVIEW

Insomnia and short sleep have been linked with weight gain and obesity. However, these findings have not been consistent across studies. We review recent evidence for the association between insomnia, short sleep, and weight gain, as well as the relationship between behavioral and pharmacological treatments for sleep and weight.

RECENT FINDINGS

The relationship between insomnia and obesity is mixed, with stronger associations between insomnia with short sleep and obesity than other presentations of insomnia. Short sleep is associated with weight gain. Z-drugs and benzodiazapines do not appear to impact weight, but many antidepressants and antipsychotics that are used for insomnia treatment do cause weight gain. The relationships between insomnia and short sleep with weight gain and obesity are inconsistent. More prospective trials are needed to identify mediators and moderators of this relationship to better develop and deliver effective interventions for both sleep and weight problems.

Evidence-Based Intervention Adaptations Within the Veterans Health Administration: a Scoping Review

BACKGROUND

Veterans receiving care within the Veterans Health Administration (VA) are a unique population with distinctive cultural traits and healthcare needs compared to the civilian population. Modifications to evidence-based interventions (EBIs) developed outside of the VA may be useful to adapt care to the VA healthcare system context or to specific cultural norms among veterans. We sought to understand how EBIs have been modified for veterans and whether adaptations were feasible and acceptable to veteran populations.

METHODS

We conducted a scoping review of EBI adaptations occurring within the VA at any time prior to June 2021. Eligible articles were those where study populations included veterans in VA care, EBIs were clearly defined, and there was a comprehensive description of the EBI adaptation from its original context. Data was summarized by the components of the Framework for Reporting Adaptations and Modifications to Evidence-based interventions (FRAME).

FINDINGS

We retrieved 922 abstracts based on our search terms. Following review of titles and abstracts, 49 articles remained for full-text review; eleven of these articles (22%) met all inclusion criteria. EBIs were adapted for mental health (n = 4), access to care and/or care delivery (n = 3), diabetes prevention (n = 2), substance use (n = 2), weight management (n = 1), care specific to cancer survivors (n = 1), and/or to reduce criminal recidivism among veterans (n = 1). All articles used qualitative feedback (e.g., interviews or focus groups) with participants to inform adaptations. The majority of studies (55%) were modified in the pre-implementation, planning, or pilot phases, and all were planned proactive adaptations to EBIs.

IMPLICATIONS FOR D&I RESEARCH

The reviewed articles used a variety of methods and frameworks to guide EBI adaptations for veterans receiving VA care. There is an opportunity to continue to expand the use of EBI adaptations to meet the specific needs of veteran populations.

Peer Support Activities for Veterans, Serving Members, and Their Families: Results of a Scoping Review

For many, including military veterans and their families, support between individuals with shared lived experiences, or peer support, has long been utilized as a way to support each other through many different challenges. Building on other reviews and guided by the seven domains of well-being in the Canadian veteran well-being framework, the objective of this paper is to describe and catalogue the nature of peer support activities and related outcomes in the veteran, serving member, and family member populations. A scoping review following the five stages outlined by Arksey and O'Malley was conducted; it was guided by the question: What is currently known about peer support activities for veterans, serving members, and their families that has been evaluated in the literature? In total, 101 publications from 6 different countries were included in this review and catalogued based on publication characteristics, participant information, peer support activity information, and peer information. Peer support activities have the potential to positively influence the well-being of veterans, serving members, and their families on a holistic level across multiple domains. This scoping review highlights the existing gaps in the literature and provides an important foundation for future research on peer support for these populations, specifically in the Canadian context.

Association of childhood abuse with behavioral weight-loss outcomes: Examining the mediating effect of binge eating severity

OBJECTIVE

The study aims were to (1) document the relationship between a history of childhood abuse and weight change during behavioral obesity treatment and (2) estimate the indirect effect of childhood abuse on weight change through binge eating severity.

METHODS

Participants (n = 431) were enrolled in a behavioral weight-loss intervention. Childhood physical and emotional abuse history and current binge eating severity were self-reported. Percent weight loss at 6 months was calculated using measured weight. Adjusted mediation models examined whether there was an indirect effect of childhood physical and emotional abuse on 6-month percent weight loss that operated through binge eating severity.

RESULTS

After covariate adjustment, childhood physical abuse, but not emotional abuse, predicted a lower percent weight loss (B = -1.78%; 95% CI: -3.10% to -0.47%). Although childhood physical and emotional abuse were positively related to baseline binge eating severity, binge eating severity did not mediate the associations between either childhood abuse type and percent weight loss.

CONCLUSIONS

Individuals with a childhood physical abuse history had a lower percent weight loss than those without such histories during behavioral obesity treatment. This effect was not explained by binge eating severity. Individuals with a history of childhood abuse may benefit from trauma-informed obesity care.

Testing a tailored weight management program for veterans with PTSD: The MOVE! + UP randomized controlled trial

Post-traumatic stress disorder (PTSD), prevalent among Veterans, increases risk for having a high Body Mass Index. Although the Veterans Health Administration (VHA) offers an evidence-based behavioral weight management program called MOVE!, participants with PTSD lose less weight than those without mental health conditions, despite comparable participation. PTSD symptoms can interfere with one's ability to be physically active and maintain a healthy diet, the key targets in weight management programs. We developed and piloted a behavioral weight management program called MOVE! + UP that targets PTSD-related weight loss barriers. MOVE! + UP includes 16 group sessions with training in evidence-based weight management strategies, coupled with Cognitive Behavior Therapy (CBT) skills to address PTSD-specific barriers. The 16 sessions also include 30-min community walks to address PTSD-related barriers that may impede exercise. Two individual dietician sessions are provided. This hybrid type 1 randomized controlled trial (RCT) will compare MOVE! + UP to standard care-MOVE!-among 164 Veterans with BMI ≥ 25 who are receiving care for PTSD. We will randomize participants to MOVE! + UP or standard care and will compare absolute post-baseline change in weight at 6 (primary outcome) and 12 (secondary outcome) months, and PTSD symptom severity at 6 and 12 months (secondary outcome). Exploratory analyses will compare the treatment conditions on treatment targets measured at 6 months (e.g., physical activity, eating behavior, social support). Finally, we will estimate intervention costs, and identify MOVE! + UP implementation barriers and facilitators. If effective, MOVE! + UP could be an efficient way to simultaneously address physical and mental health for Veterans with PTSD.
