Weight Loss Treatment for Veterans With Binge Eating

2017-08-01 13:38:21 | BioPortfolio


Inclusion Criteria: aged 21 and older, BMI>=25, and presence of recurrent binge eating on the MOVE! Survey. Exclusion Criteria: more than 4 MOVE! sessions in the prior year; active psychosis or suicidal ideation; medical or psychiatric illness, or cognitive deficits that interfere with providing consent or completing assessments, and; pregnancy or lactation.

Participants will be recruited from the VA's MOVE! Program at VA Connecticut Healthcare System (both Newington and West Haven campuses). Those participants who meet eligibility and are interested in the study will meet with a research associate who will obtain written consent. A baseline appointment will be made where the participant will complete written assessments, anthropometric measures (weight, height, blood pressure etc.), along with a blood draw. Participants will then be randomized, by luck of a draw, to either MOVE! or MOVE!+gshCBT treatment.

For those randomized to the MOVE! condition, participants will continue in the MOVE! program by meeting with the multidisciplinary team in a group setting once a week for 60 minutes, for 16 weeks. The group sessions are lead by a dietician, health psychologist, and physical therapist.

For those randomized to the MOVE!+gshCBT treatments, participants will continue in the MOVE! program as described above, but will also partake in 8 individualized sessions over a 3-month period. Participants will be given a treatment manual to read at home, ask to complete daily food logs and work with the study therapist to create goals and complete homework that is geared at examining and changing how participant think about binge eating and how that thinking affects behavior. Lastly, a walking program will also be incorporated into the treatment.

For both treatment arms, 3 months from treatment starting, then again at 9 months and 15 months, participants will be asked to complete post and follow up assessments, much like the baseline.



Design Overview To address the specific aims of this proposal, the investigators will conduct an RCT comparing MOVE! (treatment-as-usual; MOVE!) to MOVE! plus gshCBT (MOVE!+gshCBT). Overweight/obese Veterans (108 men and women) with recurrent binge eating as reported on the binge eating item from the MOVE! survey will be enrolled. Potential participants will be recruited from MOVE! group orientation meetings at two VA CT sites which take place several times per month. Major assessments will be performed by an independent evaluator at pre-treatment (baseline), at the end of gshCBT treatment (3 months), and at 6- and 12-months following treatments (9 and 15 months after randomization). Analyses are powered for the primary outcome of binge remission (categorical). Analyses for binge frequency (continuous), and eating disorder and mental health outcomes will be performed. Exploratory analyses will be conducted on treatment engagement (MOVE! session attendance) and weight outcomes (weight loss and metabolic outcomes), as well as for potential predictors and moderators (age, gender, clinical severity, and comorbidity), and correlates (change in weight control strategies and physical activity) of treatment outcome.

Participants Criteria have been kept to a minimum to increase the generalizability of findings. Inclusion Criteria: aged 21 and older, BMI>=25, and presence of recurrent binge eating on the MOVE! Survey. Exclusion Criteria: more than 4 MOVE! sessions in the prior year; active psychosis or suicidal ideation; medical or psychiatric illness, or cognitive deficits that interfere with providing consent or completing assessments, and; pregnancy or lactation. The investigators will aim for a sample that is 34% racial/ethnic minority (66% Caucasian) to be consistent with the demographics of a nationally representative sample of Veterans seeking weight management treatment through VHA3. The investigators will also aim for 25% women (75% men), a figure that represents an oversampling of women compared to the rate of 6% for all VHA users. This will allow us to examine gender as a potential predictor or moderator of treatment outcome and address the VHA's strategic plan to better serve women Veterans.

Recruitment Potential participants will be recruited from orientation sessions for MOVE! groups conducted at two sites, the West Haven and Newington campuses, of VA CT. While MOVE! is delivered in different formats (i.e., group, individual and telehealth), the group format accounts for 75% of weight management services delivered across the VHA. The Research Assistant will be given a few minutes at the beginning of each orientation session to describe the study. Orientation sessions are available to Veterans three times per month between the two sites. Names and numbers will be collected of those who are interested so that they may be contacted for individual sessions to assess interest and eligibility using the criteria above. Dr. Ruser (Co-I, Chief of Primary Care and MOVE! Physician Champion for VA CT) oversees the program at both campuses, and Dr. Dorflinger (Co-I, Health Behavioral Coordinator who is directly responsible for the delivery of MOVE!) splits her time between the two sites. According to MOVE! performance measures, a greater number of patients are seen for weight management at the Newington campus compared to the West Haven campus. The investigators plan to test, and control, for potential site differences in the analyses. In addition, Dr. Driscoll (Co-I), women Veteran's health researcher for the VHA's Women's Practice Based Research Network, and clinical supervisor for the local women's clinic, will be responsible for recruiting women Veterans into the MOVE! orientation sessions and treatment study. She has experience successfully oversampling for women Veterans in a previous trial that resulted in 25% women (compared to 6% of all VHA users)38.

Screening for "recurrent binge eating" The presence of binge eating will be determined by the MOVE! Survey, an 11-item self-report survey that must be completed prior to attending MOVE! programs. This survey was created to aid in the tailoring of MOVE! treatment for patients' specific needs. The item that assesses the presence of binge eating reads as follows: "On average, how often have you eaten extremely large amounts of food at one time and felt that your eating was out of control at that time?" The response set for this item is never, less than one time per week, one time per week, two to four times per week, or five or more times per week. Participants reporting binge eating at least one time per week will be included following published methods. These methods come from two effectiveness studies for recurrent binge eating that have been conducted with participants from a large integrated healthcare system18,19. Further assessment with the Eating Disorder Examination-Interview 12th Ed. (EDE)46, described below, will enable us to further categorize participants who meet full DSM-5 diagnostic criteria for BED (clinical BED) and those who do not (subclinical BED).

Informed consent and pre-treatment assessment If the potential participant is eligible and interested, a pre-treatment assessment of one to two sessions will be scheduled. This assessment will help to determine whether participants are able to comply with the requirements of the program (such as regular appointments and record-keeping) and also to minimize the attrition rate of the trial, since only those who complete these requirements will be enrolled. The Research Assistant will describe the study, and the consent will be reviewed verbally and in writing, before IRB written informed consent is obtained. During the pre-treatment assessment session(s), the following will be obtained/completed: anthropometric measures (height, weight, waist circumference, blood pressure; methods described below), demographic information (age, gender, race/ethnicity, etc.), self-report measures (described below), blood draw, psychiatric evaluation with the Mini-Neuropsychiatric Interview (MINI)49, and the eating disorder evaluation with the Eating Disorder Examination-Interview 12th Ed. (EDE)46.

Determination of binge status: Subclinical vs. Clinical BED The Eating Disorder Examination-Interview 12th Edition (EDE)46 is the structured diagnostic interview that is considered the gold-standard to diagnose, and assess the symptoms of, eating disorders including binge eating and eating disorder pathology. The EDE will be used to categorize participants as clinical BED (meeting full DSM-5 criteria including a binge frequency of at least one time per week on average for the past three months) or subclinical BED (reporting at least one time per week binge eating on the MOVE! survey but not meeting DSM-5 criteria for BED). The Research Assistant will be trained and supervised by Dr. Masheb (PI) who has extensive experience with the EDE. Binge status will be used as a potential covariate in analyses.

Randomization procedures Eligible patients who agree to participate and sign consent forms will be randomly assigned to MOVE! or MOVE!+gshCBT in the order in which they complete the evaluation process. Equal numbers of participants will be randomly assigned to each of the two conditions. The randomization schedule will be created with a random number generator, independent of the investigators.

Control condition: MOVE! (treatment-as-usual) Based on scientific review and practice guidelines of the NIH, and in collaboration with VHA Central Office, the MOVE! program was developed as an evidence-based weight management and physical activity initiative that included assessment and treatment procedures, clinical algorithms, patient and provider information, and instructional materials. The program was widely disseminated and implemented beginning in January 200653. Every VHA facility across the country is required to have some form of the MOVE! program, if not several programs differing in intensity, which utilize these materials. At a minimum, on-site weekly, multidisciplinary groups must be held. MOVE! group at VA CT is the most widely used weight management service and was thus chosen as the treatment-as-usual for the present study given the potential for disseminability. Research has demonstrated minimal weight losses with MOVE! and these findings have largely been attributed to poor treatment engagement (i.e., attendance) and weight gain in the year prior to treatment initiation54,55. One initiative to increase the reach and impact of weight management in the Veteran population has been to identify vulnerable subgroups of overweight/obese patients, such as those with binge eating8, pain56, and serious mental illness57. The hope is that the present study will extend this initiative.

All participants will receive MOVE! group treatment as it is delivered at VA CT. The 60-minute groups cycle every 16 weeks and are led by a physical therapist, dietitian, and/or clinical health psychology predoctoral intern. Clinicians utilize materials available on-line, and encourage the use of, but do not require or provide, food diaries. Participants in both MOVE! and MOVE!+gshCBT will be encouraged to attend these sessions throughout their involvement in the entire study (i.e., during treatment and follow-up phases). MOVE! is similarly delivered at both the VA CT West Haven and Newington facilities as both programs are overseen by Drs. Ruser and Dorflinger (Co-Is).

Experimental condition: MOVE!+gshCBT One-half of participants will be randomly assigned to MOVE!+gshCBT and will receive the MOVE! treatment described above as well as a gshCBT treatment for binge eating. gshCBT will be administered via 8 individual sessions over a 3-month treatment period. The first two sessions will be 60 minutes each and subsequent sessions will be 30 minutes. CBT has emerged as the treatment of choice for BED for its robust effects on reducing binge eating and improving the behavioral and psychological aspects of the disorder9. The gshCBT treatment will adhere to a manual developed by Dr. Masheb (PI) and generally follows the book Overcoming Binge Eating 58 that has been used by Drs. Masheb and Grilo (Co-I) in previous published studies of CBT11,21,32-35, as well as by others 12,40,59. A copy of the gshCBT manual is included in the Appendix.

Participants will be given the gshCBT manual with a schedule to read at home. During sessions, the Psychologist will use the following session guideline: 1) setting an agenda, 2) reviewing food diaries and self-monitoring, 3) introduction of new material from the manual, 4) reviewing old material and problem-solving difficulties, and 5) establishing new homework and goals. The treatment follows three stages. Stage 1 consists of presentation of the CBT model; introduction and discussion of the structure, goals, interventions, and expected outcome of treatment; education regarding binge eating and dieting; and the introduction of self-monitoring techniques for identifying problematic eating practices and triggers. Stage 2 consists of maintaining the normalized eating and self-monitoring procedures but becomes increasingly cognitively oriented. Stage 3 focuses on practicing skills, consolidation of progress and relapse prevention.

At each session participants will receive new, blank food diaries. Participants are expected to complete these diaries on a daily basis, and they will be reviewed and checked at each session by the Psychologist. If participants would like to use these food diaries for their MOVE! treatment as well, they may do so. [NOTE: Food diaries are encouraged in MOVE! but are not provided or required.] gshCBT participants will also be instructed in how to record (i.e., self-monitor) binge eating. Recording of this data will be mandatory and participants who arrive to session with incomplete food diaries or self-monitoring will be asked to use session time to complete these records for at least the previous day or two. This technique emphasizes the importance of food diaries, raises patients' awareness of their eating, allows clinicians to address any concerns about how to complete diaries, and demonstrates that diaries can be completed without too much effort. The investigators will continue this strategy through all CBT sessions until the patients arrive to sessions with diaries completed. This typically takes two sessions, however sometimes food diary non-compliance can reemerge later in treatment. In this scenario in-session diary completion is reintroduced following the same procedure. Patients will also be encouraged to gradually increase daily modest physical activity with the goal of establishing 30 minutes of activity (walking sessions or other activity) five times per week. This prescription is consistent with recommendations from several expert-based organizations (NIH and Centers for Disease Control).

Measurements Participant assessments will be conducted by the Research Assistant and independent of the treating Psychologist so that assessment will be unbiased. These will include outcomes for: binge eating and mental health; engagement and weight; weight control behaviors and physical activity, and; treatment satisfaction and adherence.

Statistical considerations

Analytic Plan. Statistical analyses will be conducted by Dr. Brenda Fenton (Co-I) who is a biostatistician and has extensive experience in statistical modeling, particularly in the analysis of longitudinal data. Baseline characteristics will be compared between the treatment groups using ANOVA and chi-squares as appropriate in order to determine the level of success of the randomization. Distributions of outcomes will be examined in order to determine if assumptions of specific model types are met. Change of model type as well as transformation of the data will be considered if model assumptions are not met. Mixed-effects models, a method for statistical modeling that uses both fixed effects and random effects, will be used to examine continuous outcomes such as binge eating frequency, mental health symptoms, and percent weight loss for completer, as well as intent-to-treat (all randomized persons), analyses. Logistic regression models will be used for categorical outcomes such as binge remission and achieving clinically meaningful weight loss (i.e., 5% weight loss or greater). Missing data and covariate adjustment will be handled.

Aim 1 addresses binge eating (primary outcome) and mental health outcomes. Binge remission (H1; defined as zero binges for the 28 days prior to the end of treatment) will be examined as a binary outcome in logistic models including treatment group and relevant covariates. Reduction in frequency of binge eating over time will be examined using mixed effects models. Previous work indicates that the outcomes may need to be log-transformed to better approximate normality11. Mental health outcomes (H2), using validated symptom scales for depression and quality-of-life, will also be examined using mixed models. Relevant demographic and clinical characteristics will be included in the logistic and mixed models, and main as well as interaction effects will be investigated.

Aim 2 addresses level of engagement in weight loss treatment (i.e., number of MOVE! treatment sessions) and weight outcome. Engagement (H1) will be explored using Poisson regression on counts of MOVE! sessions completed using a binary treatment variable (MOVE! vs. MOVE!+gshCBT). The distribution of engagement will be reviewed to determine if there is over-dispersion (in which case quasi-likelihood estimation will be used to account for it). Models will include relevant covariates such as demographic and clinical characteristics. The treatment effect on weight (H2) will be examined with a mixed effects model, as described above, using longitudinal change in percent weight loss during the intervention and follow-up phases. Categorical analyses will also be performed comparing treatments on the proportion of participants achieving 5% weight losses using logistic regression analysis.

Exploratory analyses will be performed on the metabolic outcomes (HbA1C, total cholesterol, HDL, LDL, triglycerides, systolic and diastolic blood pressure, and waist circumference) using mixed models. These outcomes were chosen for analysis to be consistent with interests of health services research although the investigators recognize that changes in these measures may not be sufficient to detect a difference. These analyses also could be important downstream in adding credibility in the eyes of patients, and providers, and could be used to enhance incentives for participation (or patient referral).

Aim 3 is an examination of predictors, moderators and correlates of treatment outcome. Predictors are variables present at baseline that influence outcome regardless of treatment condition, and moderators are variables present at baseline that influence outcome depending on the treatment condition. Potential predictors and moderators (H1) will be explored with demographic (age and gender)81, and clinical characteristics (clinical severity and comorbidity) from the relevant literature on BED82,83. Logistic and multiple regression analyses, that have been detailed conceptually and analytically by Kraemer et al.84, will be used. Associations (H2) between changes in weight control strategies and physical activity, and weight loss 71 will be examined with correlation analyses.
