Trial summary

The goal of this study was to examine the glucocorticoid and behavioral responses to a psychological stressor in obese African-American and non-Latino white adolescents. Participants were exposed to the Trier Social Stress Test (TSST) and a control condition on separate days. Read more about this study

About this study

Official title: Stress-induced Eating Behavior: Implications for Pediatric Obesity Disparities

The goal of this study was to examine the glucocorticoid and behavioral responses to a psychological stressor in obese African-American and non-Latino white adolescents. Participants were exposed to the Trier Social Stress Test (TSST) and a control condition on separate days. Immediately following each condition, participants were provided with snacks to eat at their leisure. Reactivity was assessed via salivary cortisol and alpha-amylase area under the curve (AUC), and adolescents were categorized as high or low reactors.

Read the detailed description

In the United States, pediatric obesity has more than tripled in the last 30 years, particularly among certain racial/ethnic groups including African-Americans. This disparity is partially attributable to greater exposure to psychological stress reported in this group (relative to non-Latino whites). Chronic psychological stress leads to weight gain directly through prolonged exposure to biological stress mediators such as cortisol and indirectly through behavioral pathways involving cortisol-induced increases in food consumption. An exciting arena of scientific advancements is focusing on identifying the specific pathways through which chronic stress influences eating behavior with emerging evidence to suggest that food intake, which is commonly increased during periods of stress, may serve as one key mechanism linking stress and obesity, particularly in African-American youth who are disproportionately exposed to chronic stress and have greater access to, and consumption of, energy-dense palatable foods. It is critical to advance understanding of the interplay between stress and food intake in understanding racial/ethnic disparities in pediatric obesity because stress eating represents a modifiable health behavior. That is, increased food intake during periods of elevated stress can be targeted for intervention in ways that may ameliorate the deleterious effects of stress on obesity risk. This project investigated the role of stress eating as a pathway linking chronic stress and obesity in African-American and non-Latino white adolescents.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Acute Laboratory StressorBehavioural

    Also called Trier Social Stress Test

    The TSST was 20 minutes long and consisted of a five-minute instructional period where participants listened to a pre-recorded tape; a five-minute speech preparation period; a five-minute challenging serial subtraction task; and a five-minute videotaped public speaking task in front of a panel of three evaluative, non-affirming judges dressed in white coats.

  • Low affect videoBehavioural

    The 20-minute TSST was replaced with a 20-minute low-affect educational film screening.

Study groups in NCT03997149
Study groupRoleWhat they receive
Stress ConditionExperimentalThe stress condition involved the Trier Social Stress Test (TSST), a standardized laboratory stressor designed to elicit psychological stress and cortisol responses. Following the TSST, participants were brought to a separate room, instructed to rest and given the option to eat at their leisure. Books and magazines were included in the room for the participant to utilize.
Receives: Behavioral: Acute Laboratory Stressor
Rest ConditionPlacebo comparatorParticipants completed a control condition on a separate day. This condition followed the same sequence of events as the stress condition with the exception that the 20-minute TSST was replaced with a 20-minute low-affect educational film screening.
Receives: Behavioral: Low affect video

What is being measured

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

  1. Food consumption

    Change in grams of each food consumed during the control and stress conditions were recorded and calories were calculated using the corresponding nutritional labels.

    Measured: 2 hours

Secondary outcomes (2)
  1. Salivary cortisol area under the curve

    During the control and stress conditions, saliva samples were taken at times 10, 25, 58, 88 and 118 minutes after arrival to analyze cortisol responses to the TSST. Area under the curve was calculated from the initial cortisol sample collected to the final cortisol sample collected: [AUC=(x2+x1)/(t2-t1) + (x3+x2)/(t3-t2) + (xk+xj)/(tk-tj)].

    Measured: 2 hours

  2. Salivary alpha amylase area under the curve

    During the control and stress conditions, saliva samples were taken at times 10, 25, 58, 88 and 118 minutes after arrival to analyze alpha amylase responses to the TSST. Area under the curve was calculated from the initial alpha-amylase sample collected to the final alpha amylase sample collected [AUC=(x2+x1)/(t2-t1) + (x3+x2)/(t3-t2) + (xk+xj)/(tk-tj)].

    Measured: 2 hours

Questions about this trial

What is this clinical trial studying?

A study testing Acute Laboratory Stressor and Low affect video in people with Stress and Eating Behavior, run by University of Michigan at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Food consumption (time frame: 2 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Jun 2019.
