3-Dimensional Optical Scanning for Malnutrition in Eating Disorders

This study, called 3D-ED, is looking at new ways to understand and treat malnutrition in young people with anorexia nervosa (AN) or atypical anorexia nervosa (AAN). Instead of just using body weight, researchers will use a special infrared scanner to measure body composition (how much fat and muscle you have) while you are in the hospital. They want to see how these measurements relate to how much nutrition you need, how well you recover in the hospital, and your recovery over the next year. The goal is to create more personalized treatment plans to help people with eating disorders get better. You may be able to join if you are 15-26 years old, have AN or AAN, and need to be hospitalized due to medical instability. The study is currently unclear on its recruitment status.

Study design
This is an observational study, meaning researchers will collect information without giving any specific treatments. It plans to include 90 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Researchers will look at recovery outcomes over the year following hospitalization.

Eligibility criteria

Inclusion

Diagnosis of anorexia nervosa (AN) or atypical anorexia nervosa (AAN), restricting or purging subtype, per DSM-5
Age 15 to 26 years
Medical instability warranting an inpatient hospitalization defined by either:
Extreme AN is defined as BMI below 15 kg/m2 or serious medical complications warranting admission to ACUTE (Denver Site).

Exclusion

Bulimia nervosa
Another primary diagnosis causing malnutrition (not an eating disorder)
Current active suicidality
Metal implants or devices that interfere with study procedures

What this trial measures

  • Refeeding intensity: caloric load to achieve medical stability (predicted by baseline ORMIz)From hospital admission to medical stability, up to 4 weeks

    Total caloric load required to restore medical stability during hospitalization, analyzed as a function of baseline organ residual mass index z-score (ORMIz). Primary hypothesis (Aim 1, H3): lower baseline ORMIz predicts greater refeeding intensity, including higher caloric load and more refeeding complications such as edema and electrolyte shifts. This is the endpoint on which the study is powered.
