Brief Summary:
To determine whether reducing loss of control eating (LOC) with Interpersonal Psychotherapy-Weight Gain (IPT-WG) will be effective for adolescent military-dependents who report such behavior. The investigators will examine whether IPT-WG influences body weight gain trajectories and prevents worsening disordered eating, psychosocial problems, and metabolic functioning among military dependents at heightened risk for adult obesity and disordered eating. This study will provide key efficacy data for a new promising obesity prevention program for youth from military families.

Detailed Description:
The prevalence of overweight among military personnel and their dependents is at a rate similar to that of the civilian population. Nearly 30% of adolescent dependents are overweight, including approximately 15-17% who are obese, placing them at high risk for impairments in metabolic functioning, type 2 diabetes, and adult obesity. Youth who are overweight (body mass index, kg/m2, BMI ≥ 85th percentile) are at high risk for excess weight gain as they grow. Since effective weight loss and maintenance treatments are rare, prevention may be the most important approach to reducing the high prevalence of obesity. To date, most pediatric obesity prevention programs have been met with limited success. To address those at greatest risk for obesity, more targeted approaches may be required. There is a need to reduce prospectively identified risk factors in order to prevent excess weight gain in youth at high risk for adult obesity. The most common disordered eating behavior among overweight adolescents is loss of control (LOC) eating, during which the feeling of being unable to stop eating is experienced. LOC eating predisposes youth to gain excessive weight and fat. Thus, LOC eating is likely to be an important contributor to obesity in susceptible individuals. Decreasing LOC in adolescents may prevent excess weight gain. Investigators at the Uniformed Services University of the Health Sciences (USUHS) is in partnership with Ft. Belvoir Community Hospital (FBCH) and Walter Reed National Military Medical Center (WRNMMC) to test the effectiveness of IPT-WG to slow the trajectory of weight gain in overweight adolescent boys and girls who report LOC and prevent worsening disordered eating and metabolic functioning. The unique stress burdening the children of military personnel while the country is at war suggests that obesity prevention programs targeting interpersonal stress and promoting positive social functioning may be especially timely in this population. It is hypothesized that IPT-WG will decrease LOC eating and related eating behaviors and, in turn, prevent excess weight gain and the development of exacerbated disordered eating in adolescent children of military personnel. Secondary to the prevention of excess weight gain, youth will experience improvements in metabolic functioning.

Masking: None (Open Label)

Arm Intervention/treatment
Experimental: Interpersonal Psychotherapy (IPT-WG)
IPT-WG targets the difficult social functioning and stressful events that are associated with loss of control eating and that are highly relevant to the adolescent children of military personnel.
Behavioral: Interpersonal Psychotherapy
IPT-WG involves one initial 1.5-hour individual session, and 12 weekly 90-minute group sessions. The IPT-WG group sessions follow 3 phases (initial, middle, and termination) and use the interpersonal inventory to identify interpersonal problems that might be contributing to or exacerbated by LOC eating. A framework of common problem areas is used to teach interpersonal problem-solving and communication skills and educate youth about risk factors for excessive weight gain and warning signs such as eating in response to negative affect as opposed to hunger, or feeling a sense of LOC while eating.

Active Comparator: Health Education (HE)
HE improves knowledge on various health topics including, alcohol, drug and tobacco use, depression and suicide, nutrition and body image, nonviolent conflict resolution, sun safety, exercise, and domestic violence.
Other: Health Education
The HE group is based upon the "HEY-Durham" health program designed by researchers at Duke University. This program, designed to be delivered to youth attending community high schools, was adapted to a 12-week program (each session is 90 minutes). Additionally, individuals will attend a pre-group individual meeting with the group leaders to review family health history.The curriculum includes focus on various health topics, including alcohol, drug and tobacco use, depression and suicide, nutrition and body image, nonviolent conflict resolution, sun safety, exercise, and domestic violence. Session content will be largely identical for boys and girls, with the exception of gender-specific videos and articles (e.g., on body image), which will be tailored for each sex.




Primary Outcome Measures :
  1. Participant Weight [ Time Frame: Change in weight from baseline to 3 years post-treatment ]
    Weight will be measured


Secondary Outcome Measures :
  1. Presence of binge eating [ Time Frame: Change in presence of binge eating from baseline to 1 year post-treatment ]
    The Eating Disorder Examination (EDE) will be administered to assess for the presence of binge eating. The EDE identifies three types of eating episodes: objective binge eating (overeating with LOC), subjective binge eating (LOC without objective overeating as assessed by the interviewer, but viewed as excessive by the interviewee), and objective overeating (overeating without LOC), as well as the range of compensatory behaviors described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).

  2. Waist Circumference [ Time Frame: Change in waist circumference from baseline to 3 years post-treatment ]
    Waist circumference will be measured using a flexible measuring tape.

  3. Blood Pressure [ Time Frame: Change in blood pressure from baseline to 3 years post-treatment ]
    Blood pressure will be measured using an automatic blood pressure cuff.

  4. Triglycerides [ Time Frame: Change in triglycerides from baseline to 3 years post-treatment ]
    Blood will be drawn to collect a sample for the measurement of triglycerides.

  5. HDL Cholesterol [ Time Frame: Change in HDL cholesterol from baseline to 3 years post-treatment ]
    Blood will be drawn to collect a sample for the measurement of HDL.

  6. Insulin Function [ Time Frame: Change in insulin sensitivity from baseline to 3 years post-treatment ]
    Blood will be drawn to collect a sample for the measurement of insulin.

  7. Glucose [ Time Frame: Change in glucose from baseline to 3 years post-treatment ]
    Blood will be drawn to collect a sample for the measurement of glucose.

  8. Hemoglobin A1c [ Time Frame: Change in hemoglobin A1c from baseline to 3 years post-treatment ]
    Blood will be drawn to collect a sample for the measurement of hemoglobin A1c.

  9. BMI Percentile [ Time Frame: Change in BMI percentile from baseline to 3 years post-treatment ]
    Height and weight will be measured and BMI percentile calculated
