Title: Preventing Excessive Weight Gain in Adolescent Girls at High-Risk for Adult Obesity
Brief Summary: This study will examine whether interpersonal psychotherapy (IPT) can help reduce excessive weight gain in adolescent girls. It will compare the effectiveness of IPT with a teen health education program in preventing weight gain.

Adolescent girls between 12 and 17 years of age who are at risk for becoming overweight adults, by virtue of being above average weight and experiencing episodes of loss of control over eating, may be eligible for this study. Candidates are screened in two visits with the following procedures:

Visit 1

* Height and weight measurements.
* Interview and questionnaires about the child s general health, social and psychological functioning and eating patterns and behaviors.

Visit 2

* Physical examination, blood and urine tests.
* DXA scan to measure body fat, muscle and bone mineral content.
* Laboratory test meal. The child fills out a rating scale about her level of hunger and is then given a food buffet from which she is instructed to eat as much as she wants. Immediately after eating, the child again completes the hunger rating forms.
* Interview about the child s mood and psychological functioning.

Participants are assigned at random to either the IPT or teen health education program. All participants have a 1- to 1 1/2-hour individual session with a therapist, followed by 12 weekly group sessions of 1 1/2 hours each in their assigned program. They are assessed at the end of the program with questionnaires and body measurements. They return to the clinic after 6 months for body measurements, blood test, DXA scan, questionnaires, interview and a test meal, and again at 1 year for body measurements, questionnaires and a DXA scan.


Options:
A: Inclusion Criteria:

* Subjects must be between the ages of 13.00 and 17.99 at week 0 (Baseline).
* Subjects must have a BMI ≥ 95th percentile for age and gender using the CDC data (see Appendix), but must weigh less than 300 pounds (\<136 kilograms) when measured during the initial physical exam at week 0 (Baseline). BMI will be calculated as follows; weight in kilograms  \[height in meters\]2. This cutoff has been established due to the weight-bearing limits of the table used in performing the DXA scan. Once enrolled, if a subject's weight progresses above 300 pounds, s/he may continue in the study whether it is possible to perform DXA or not.
* Completion of informed consent/assent process

Exclusion Criteria:

* Known diabetes as defined by the American Diabetes Association criteria
* Prior drug therapy to treat diabetes or insulin insensitivity, including any form of insulin or insulin analogs; or any oral antidiabetic medication; acarbose, acetohexamide, chlorpropamide, glimepiride, glipizide, glyburide, metformin, pioglitazone, repaglinide, rosiglitazone, tolazamide, tolbutamide or troglitazone.

B: * INCLUSION CRITERIA:

Volunteers will qualify if they meet the following criteria.

* Female.
* Age 12 17 years.
* BMI between 75th and 97th percentile.
* English speaking.
* Good general health.
* Participants must have normal laboratory testing, including negative urine glucose and normal electrolytes, hepatic, and thyroid function, or they will be referred for treatment.

EXCLUSION CRITERIA:

Individuals will be excluded (and referred to non-experimental treatment programs as needed):

* Presence of major illnesses: renal, hepatic, gastrointestinal, most endocrinologic (e.g., Cushing syndrome, hyper- or hypothyroidism), hematological problems or pulmonary disorders (other than asthma not requiring continuous medication). Non-serious medical illnesses, such as seasonal allergies, will be reviewed on a case-by-case basis.
* Presence of an obesity-related medical complication that would require a more aggressive weight loss intervention approach. Such comorbidities include hyperlipidemia (LDL-cholesterol greater than 160 mg/dL), hypertension (defined by age-, sex-, and height- specific standards fasting hyperglycemia (fasting glucose greater than 100 mg/dL) and nonalcoholic steatohepatitis (ALT above NIH Clinical Center laboratory norms with consistent radiologic findings and absence of another cause such as infectious hepatitis).
* Regular use of prescription medications. Oral contraceptive use will be permitted, provided the contraceptive has been used for at least two months before starting study. Individuals taking medications for most conditions will be excluded, but medication use for non-serious conditions (e.g., acne) will be considered on a case-by-case basis. In particular, participants currently prescribed SSRIs, neuroleptics, tricyclics, stimulants, or any medication known to affect body weight or eating will be excluded.
* Current involvement in psychotherapy or a structured weight loss program.
* Weight loss during the past 2 months for any reason exceeding 3 per cent of body weight.
* Pregnant or recently pregnant girls (within 1 year of delivery).
* History of an eating disorder or a current eating disorder (other than binge eating disorder) as determined by medical history or if uncovered during the study s structured clinical interviews. Subjects found to have an eating disorder other than binge eating disorder at baseline will be referred to mental health specialists for further evaluation and treatment.
* Current pregnancy or breast feeding. A negative pregnancy test before starting the study will be required. Because pregnancy is a state in which weight gain is expected and appropriate, pregnant individuals would not be suitable for this study. Sexually active females must be using an effective form of birth control. These methods include total abstinence (no sex), oral contraceptives ( the pill ), an intrauterine device (IUD), levonogestrol implants (Norplant), or medroxyprogesterone acetate injections (Depo-provera shots). If one of these cannot be used, contraceptive foam with a condom is recommended. Should a participant in the IPT-WG group become pregnant during the 12 weeks of therapy, she will be excluded from the group sessions. The girl s IPT-WG therapists will closely assist her in obtaining an appropriate referral to a community mental healthcare provider. The IPT-WG leaders will request a release of information so that they may communicate with the community therapist in order to facilitate a smooth transition for the girl.
* Individuals who have DSM-IV-TR major depressive disorder, psychoses, current substance or alcohol abuse, conduct disorder, or a diagnosed psychiatric disorder that, in the opinion of the investigators, would impede competence or compliance or possibly hinder completion of the study. Individuals whose parents or guardians have current substance abuse or a diagnosed psychiatric disorder or other condition that, in the opinion of the investigators, would impede adherence with the study.
* Inability to participate in a group due to psychiatric or cognitive functioning. School placement (e.g. grade level) will be used as an estimate of cognitive functioning. The decision to include or exclude subjects for this reason is left entirely to the discretion of the investigators.
* Any other condition in the adolescent or her parents or guardians that, in the opinion of the investigators, would impede compliance or possibly hinder completion of the study.
C: Inclusion Criteria:

* Subject's body mass index (BMI) was \>= 27 kg/m(2) and \<= 45 kg/m(2) or their BMI was \>= 25 kg/m(2) and \< 27 kg/m(2) with waist circumference of \>= 102 cm in males or \>= 88 cm in females.
* Medical history positive for:

  * Preexisting cardiovascular disease (i.e., coronary artery disease, cerebrovascular disease, or peripheral arterial occlusive disease) and/or
  * Type 2 diabetes mellitus with at least 1 other risk factor (i.e., dyslipidemia, controlled hypertension, current smoker, or diabetic nephropathy with evidence of microalbuminuria)

Exclusion Criteria:

* History of recent myocardial infarction.

D: * INCLUSION CRITERIA:

Good general health.

Age 2 to 18 years.

EXCLUSION CRITERIA:

Volunteers will be excluded for the following reasons:

Presence of renal, hepatic, gastrointestinal, most endocrinologic (e.g., Cushing's syndrome) or pulmonary disorders (other than asthma not requiring continuous medication);

Individuals who have, or whose parent or guardians have, current substance abuse or a psychiatric disorder or other condition which, in the opinion of the investigators, would impede the ability to give informed consent or possibly hinder completion of the study;

Subjects who regularly use prescription medications are not eligible. The use of over-the-counter medications will be reviewed on a case-by-case basis;

For those sub-studies involving MRI, inability to undergo MRI (e.g., volunteers with metal within their bodies including cardiac pacemakers, neural pacemakers, aneurysmal clips, shrapnel, ocular foreign bodies, cochlear implants, non-detachable electronic or electromechanical devices such as infusion pumps, nerve stimulators, bone growth stimulators, etc. that are contraindications).
