Brief Summary

Purpose: This study aims to take the procedural and research-based lessons learned from a pilot weight loss intervention (IRB # 13-02563-XP), conducted by The University of Tennessee Health Science Center in 2013, and apply them to the current study of 204 active duty military personnel. The pilot study translated and tailored the Look Ahead weight loss intervention to an overweight/obese active duty U.S. Air Force population, while accommodating the lifestyle and environment that is unique to military members and evaluate materials and procedures used. Rationale: Being overweight is now by far the leading medical reason for rejection in the military. Unfortunately, the impact of weight problems on the military does not stop with those turned away from military service. From 1998 to 2008, the Armed Forces Health Surveillance Center reported the percent of active military members who experienced medical encounters for overweight or obesity significantly increased. The estimated total days of work lost from absenteeism associated with active-duty personnel who are overweight or obese was 658,000. Using Department of Defense (DOD) estimates of average daily based, it was estimated that overweight and obesity costs the DOD $103 million dollars in health care costs annually. Note this estimate is for active duty personnel only. Furthermore, obesity is a major cause for the discharge of uniformed personnel. The current study is inspired by the successful Look Ahead trial, a behavioral science obesity intervention treatment program that included: a collaborative approach, education, behavioral support, and motivational interviewing. The unique nature of this weight reduction study is significant. To our knowledge, there had not been a successful translation of a highly efficacious obesity treatment in the military until The University of Tennessee Health Science Center implemented a pilot version of the Fit Blue program for active duty U.S. Air Force members in 2013. Following a successful pilot and extant results from the Look Ahead trial, Investigators expect success during the full scale Fit Blue study.

Outcome Measures

Primary Outcomes (1)

  • Percent Weight Loss (Baseline to 12 Months)

    The primary data analysis will adhere to the intention-to-treat principle and in the final analysis, the participants will be categorized according to their initial randomization. Investigators will be using the baseline weight as a covariate in the final primary model where the two arms will be compared in terms of the percentage of weight loss.

    12 month intervention

Secondary Outcomes (3)

  • The Relationship Between Attendance and Percent Weight Loss

    12 month intervention

  • The Relationship Between Dietary and Physical Activity Self-monitoring Adherence and Percent Weight Loss

    12 month intervention

  • The Relationship Between Self-weighing on Weight Loss

    12 month intervention

Study Arms (2)

Counselor-Initiated

EXPERIMENTAL

Participants will receive 28 telephone sessions over a 12 month period by interventionists trained in behavior change skills and motivational interviewing techniques. Participants will be asked to monitor food intake and physical activity using the LoseIt website/app and weight daily using a Body Trace e-scale. Participants will receive feedback on self-monitoring through e-mail. Dietary goals will be based on weight and participants' weight-loss progress. Participants will be encouraged to replace 2 meals and a snack with meal replacements (provided). Participants will be asked to gradually increase their moderate to vigorous exercise to 225-250 minutes per week. The Toolbox includes additional treatment options (e.g., food scales, exercise videos, cookbooks) for those who wish to take advantage of them. There will be several challenges that will provide a specific goal (e.g. increase self-monitoring), with a small award for completion.

Self-Paced

ACTIVE COMPARATOR

The Self-paced group uses a less intense approach, where the participants can receive the same telephone counseling sessions as the counselor-initiated group, only if they call the counselor. Participants will be asked to monitor food intake and physical activity using the LoseIt website/app and weight daily using a Body Trace e-scale. Participants will receive feedback on self-monitoring through e-mail only upon request. Dietary goals will be based on weight and participants' weight-loss progress. Participants will be asked to gradually increase their moderate to vigorous exercise to 225-250 minutes per week.

Behavioral: Phone-based sessions upon requestBehavioral: Weight self-monitoringBehavioral: Dietary and physical activity self-monitoringBehavioral: Dietary goalsBehavioral: Physical activity goalsBehavioral: Tailored interventionist feedback upon request

Interventions

28 sessions will be reviewed weekly and then bi-weekly with a trained motivational interviewing counselor for those individuals randomly assigned to the counselor-initiated condition.

Counselor-Initiated

For those individuals randomly assigned to the self-paced condition, the 28 sessions are still available to them, the participant has to call to initiate sessions.

Self-Paced

Each randomized participant will be given a Body Trace scale that will electronically record their weight.

Counselor-InitiatedSelf-Paced

Each randomized participant will be given a free account to Lose It! Premium, an online food/activity diary for self-monitoring.

Counselor-InitiatedSelf-Paced

Randomly assigned participants to the counselor-initiated condition will receive feedback on their progress throughout their sessions with their assigned interventionist.

Counselor-Initiated
Dietary goalsBEHAVIORAL

Each randomized participant will receive a daily calorie goal range based on their current weight, gender, and BMI.

Counselor-InitiatedSelf-Paced

Randomized participants will receive coupons for meal replacements including oatmeal and popcorn.

Counselor-Initiated

Each participant will complete the Global Physical Activity Questionnaire which will determine their weekly exercise goals.

Counselor-InitiatedSelf-Paced
ToolboxBEHAVIORAL

The toolbox includes additional treatment options for those who wish to take advantage of them. Items may include: food scales, cookbooks, etc. These items may be checked out and must be returned prior to the completion of the study.

Counselor-Initiated
ChallengesBEHAVIORAL

There will be several challenges designed to increase participant interest and provide a specific goal (e.g., increase self-monitoring). Participants who successfully completed the challenges will be given a small award.

Counselor-Initiated

Randomly assigned participants to the self-paced condition have the option to receive feedback on their progress upon request.
