Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 10 to 16 years
  • All sexes
  • Healthy volunteers accepted
  • Child

Study population: The study aims to identify and recruit 340 boys and girls aged 10 to 16 years. The sample will be screened on the telephone in attempt to achieve a comparable sex and race distribution. An oversample will be taken for severely obese youth so they comprise approximately 50% of the sample (with the other 50% being distributed among normal weight, overweight, and obese status).

Who may be able to join

  • Age 10-16 years
  • Body weight < 500 lbs.
  • Ability to understand instructions and complete all study procedures

Who cannot join

  • Pregnant
  • On a restrictive diet due to illness
  • Significant physical or mental disabilities that impede walking, wearing accelerometer or GPS, or responding to EMA.

About this study

Official title: Translational Investigation of Growth and Everyday Routines in Kids (TIGER Kids)

The purpose of this study is to determine the effect of severe obesity on physical activity, sedentary behavior and cardiometabolic risk factors during childhood and adolescence and whether these associations are modified by race. Additionally, the study will investigate the contributions of (total, regional, and depot-specific) fat accumulation on changes in physical activity, sedentary behavior, and cardiometabolic risk factors during childhood and adolescence.

Read the detailed description

The proposed study will establish a prospective pediatric cohort to identify intervention targets based on the location, timing, barriers, and facilitators of current physical activity and sedentary behavior in a child's day. The project will be a prospective examination of 340 African American and White girls and boys aged 10 to 16 years, including 50% who are classified as severely obese. State-of-the-art technology will be used including accelerometry to quantify physical activity, magnetic resonance imaging to quantify fat accumulation, and geographic position system and ecological momentary assessment to identify environmental and socio-emotional barriers and facilitators. In further detail, this study will examine the following objectives:

Objective 1: Determine the effect of severe obesity on physical activity, sedentary behavior, and cardiometabolic risk factors during childhood and adolescence and whether these associations are modified by race.

Objective 2: Investigate the contribution of (total, regional, and depot-specific) fat accumulation on changes in physical activity, sedentary behavior, and cardiometabolic risk factors during childhood and adolescence.

Objective 3: Determine barriers and facilitators of physical activity that are related to obesity, including environmental and socio-emotional factors.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective 1 Primary Outcome: Change in Minutes of Sedentary Behavior, Light Physical Activity, and Moderate-to-vigorous Physical Activity

    Physical activity and sedentary behavior will be measured by a triaxial accelerometer (Actigraph GT3X+, Actigraph of Ft. Walton Beach, FL). The participant will be instructed to wear the accelerometer on an elasticized belt, on the left mid-axillary line. The Actigraph is one of the most common accelerometers used for scientific purposes. Participants will be encouraged to wear the accelerometer 24-hours per day for at least 7-days (plus an initial familiarization day and the morning of the final day), including 2 weekend days. Participants will also complete a Lifestyle survey to collect information including diet and physical activity habits.

    Measured: Baseline and Year 2

  2. Objective 2 Primary Outcome: Relationship Between Total Fat Accumulation and Change in Sedentary Behavior - Visceral Adipose Tissue

    Body composition will be determined by DXA and MRI. With DXA, total body fat and trunk fat will be measured by whole-body DXA using a GE iDXA scanner (GE Medical Systems, Milwaukee, WI) to quantify total and regional body fat (including trunk fat). MRI - Visceral fat, i.e. visceral adipose tissue, will be measured by water-fat shifting MRI using the General Electric Discovery 750w 3.0 Tesla (GE Medical Systems, Milwaukee, WI). IDEAL-IQ imaging technique will be used to generate water-only, fat-only, in-phase, and out-of-phase echoes in a single acquisition with a 20-second breath-hold. Sedentary behavior will be measured by a a triaxial accelerometer as described in outcome 1. Participants will also complete a Lifestyle survey to collect information including physical activity habits.

    Measured: Baseline and Year 2

  3. Objective 2 Primary Outcome: Relationship Between Total Fat Accumulation and Change in Sedentary Behavior - Adiposity

    Body composition will be determined by DXA and MRI. With DXA, total body fat and trunk fat will be measured by whole-body DXA using a GE iDXA scanner (GE Medical Systems, Milwaukee, WI) to quantify total and regional body fat (including trunk fat). MRI - Visceral fat, i.e. visceral adipose tissue, will be measured by water-fat shifting MRI using the General Electric Discovery 750w 3.0 Tesla (GE Medical Systems, Milwaukee, WI). IDEAL-IQ imaging technique will be used to generate water-only, fat-only, in-phase, and out-of-phase echoes in a single acquisition with a 20-second breath-hold. Sedentary behavior will be measured by a a triaxial accelerometer as described in outcome 1. Participants will also complete a Lifestyle survey to collect information including physical activity habits.

    Measured: Baseline and Year 2

  4. Objective 2 Primary Outcome: Relationship Between Total Fat Accumulation and Change in Sedentary Behavior - Body Fat (%)

    Body composition will be determined by DXA and MRI. With DXA, total body fat and trunk fat will be measured by whole-body DXA using a GE iDXA scanner (GE Medical Systems, Milwaukee, WI) to quantify total and regional body fat (including trunk fat). MRI - Visceral fat, i.e. visceral adipose tissue, will be measured by water-fat shifting MRI using the General Electric Discovery 750w 3.0 Tesla (GE Medical Systems, Milwaukee, WI). IDEAL-IQ imaging technique will be used to generate water-only, fat-only, in-phase, and out-of-phase echoes in a single acquisition with a 20-second breath-hold. Sedentary behavior will be measured by a a triaxial accelerometer as described in outcome 1. Participants will also complete a Lifestyle survey to collect information including physical activity habits.

    Measured: Baseline and Year 2

  5. Objective 2 Primary Outcome: Relationship Between Total Fat Accumulation and Change in Sedentary Behavior. - Waist Circumfrence

    Body composition will be determined by DXA and MRI. With DXA, total body fat and trunk fat will be measured by whole-body DXA using a GE iDXA scanner (GE Medical Systems, Milwaukee, WI) to quantify total and regional body fat (including trunk fat). MRI - Visceral fat, i.e. visceral adipose tissue, will be measured by water-fat shifting MRI using the General Electric Discovery 750w 3.0 Tesla (GE Medical Systems, Milwaukee, WI).

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Dec 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective 1 Primary Outcome: Change in Minutes of Sedentary Behavior, Light Physical Activity, and Moderate-to-vigorous Physical Activity (time frame: Baseline and Year 2). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02784509, which also lists 18 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Dec 2024.
