Brief Summary:
The overall objective of the proposal is to evaluate the ability of ultrasound to predict the body composition of toddlers in the outpatient clinical setting and to evaluate the relationship between body composition and neurodevelopment.

Condition or disease Intervention/treatment
Prematurity Device: Ultrasound

Detailed Description:

The investigators will address the hypothesis in the following Specific Aims:

Specific Aim 1: Validate ultrasound as a method to measure whole body fat mass and fat-free mass in toddlers. Body composition will be assessed using ultrasound measurements and the validated method of air displacement plethysmography (ADP).

Specific Aim 2: Determine the effect of a handheld Force-Measuring Ultrasound Probe on intra- and inter-observer variability in ultrasound measurements. A device which measures the force applied to the ultrasound probe will be used to obtain measurements of muscle and adipose tissue thickness (biceps, abdomen, and quadriceps) in toddlers.

Study Type : Observational
Estimated Enrollment : 80 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Use of Bedside Ultrasound to Monitor Body Composition and Neurodevelopmental Outcomes in Formerly-Premature Toddlers
Actual Study Start Date : July 20, 2018
Estimated Primary Completion Date : January 2025
Estimated Study Completion Date : January 2027

Group/Cohort Intervention/treatment
Formerly-Premature Toddlers
Data will be used to create and evaluate predictive equation
Device: Ultrasound
Ultrasound, ADP, bioimpedance measurements




Primary Outcome Measures :
  1. Ultrasound Measurements [ Time Frame: through study completion, up to 2 years ]
    Tissue thickness (adipose and muscle) will be measured in cm using the ultrasound probe.


Secondary Outcome Measures :
  1. Body Composition Measurements [ Time Frame: through study completion, up to 2 years ]
    Fat and fat-free mass will be measured in kilograms using bioimpedance and air displacement plethysmography.

  2. Neurodevelopmental Status for 2 year olds [ Time Frame: through study completion, up to 2 years ]
    Bayley Scales of Neurodevelopment III will be used to measure neurodevelopmental status at 2 years of age, including cognition, language, and motor scores (composite scoring for each area: Cognitive, 55-145; Language, 47-153; Motor, 46-154).

  3. Neurodevelopmental Status for 3 and 4 year olds [ Time Frame: through study completion, up to 2 years ]
    Weschler Preschool and Primary Scale of Intelligence (WPPSI) at 3 and 4 years of age will be used to measure neurodevelopmental status for toddlers 3, 4, or 5 years of age. Quotient and Composite scores have a mean of 100 and a standard deviation of 15. Subtest scaled scores have a mean of 10 and a standard deviation of 3.
