Studies Enrolling Volunteers


Military personnel and Civilians Needed for Nutrition Research Study

Purpose: Determine how body weight and body composition impacts immune function, skin barrier restoration time, skeletal muscle inflammation and nutrient status.

  • Determine the effect of body composition on nutrient status
  • Determine whether future studies, to test nutrition interventions to improve immune function, are warranted

Army Comprehensive Body Composition (ACBC) Study

U.S. Center for Initial Military Training (CIMT), through U.S. Army Training and Doctrine Command (TRADOC), has directed U.S. Army Research Institute of Environmental Medicine (USARIEM) to lead the Army Comprehensive Body Composition (ACBC) study to provide contemporary data regarding the body weight and composition of the force that may inform potential future changes to the Army Body Composition Program (ABCP). The population of the study, approximately 2,500 Soldiers, is to include Active, Reserve, and Army National Guard Soldiers representative of diverse backgrounds, including age, sex, and race/ethnicity.
