About this study

Official title: Sleep, Biological Stress, and Health Among Toddlers Living in Socioeconomically Disadvantaged Homes

A longitudinal study to examine the relationships among sleep characteristics, stress, and child behavior problems in a community sample of toddlers (12-24 months- ages 12-15 months at enrollment) living in socioeconomically disadvantaged homes

Read the detailed description

The purpose of this study is to examine the relationships among sleep characteristics, stress (allostatic load), and health among toddlers living in economically stressed communities. Sleep difficulty, including short sleep duration and poor sleep efficiency, is closely related to measures of stress, including interleukin (IL-6), cortisol, c-reactive proteins (CRP), secretory immunoglobulin A (SIgA), and body mass index (BMI) and may therefore contribute to 'wear and tear' on the body (allostatic load), a problem that places children at high risk of physical and mental health problems. Young children who live with socioeconomic adversity are especially vulnerable to both sleep difficulty and higher levels of physiologic stress (allostatic load).

What participants receive

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

  • Monitoring SleepOther

    An accelerometer will be placed on the wrist or ankle of the child while the child sleeps in their home. Caregivers will be instructed to keep the accelerometer on their toddler's ankle to measure sleep duration, latency and sleep efficiency. Seven nights of data will be obtained because actigraphy is most reliably measured in young children over this time frame.

  • stress biomarkersOther

    Salivary and hair cortisol measurements were used to obtain a change in baseline from 12 to 24 months. Data on the timing of the saliva collection will be collected using a Medical Electronic Monitoring System (MEMScapTM) - a digital memory cap that records the timing and frequency of opening.

    Cortisol will be measure in the morning and bedtime samples. A small amount of hair (30mg) will be cut from the posterior vertex of the child's head. Due to the expected variability in hair length of toddlers, documentation of hair length will be completed. Each centimeter represents 1 month history of stress and ideally 3 cm of hair length will be collected to provide a three month history of stress.

What is being measured

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

  1. Sleep monitoring

    Sleep characteristics will be measured by an accelerometer on the wrist or ankle to measure sleep efficiency.

    Measured: 9 days

  2. Caregiver report

    Caregivers will complete the Brief Infant Sleep Questionnaire

    Measured: 12 to 36 months

  3. Sleep diary

    Caregivers will complete a sleep diary to record their toddler's sleep for time period when an accelerometer will be worn by the child.

    Measured: 12 to 24 months

  4. Behavioral monitoring

    Toddler behavior problems will be assessed using the Brief Infant Toddler Social and Emotional Assessment (BITSEA).

    Measured: 12 to 36 months

Secondary outcomes (3)
  1. Cortisol biomarker

    A small amount of hair (30mg) will be cut from the posterior vertex of the child's head. The samples will be tied together with the scalp end noted.

    Measured: 12 to 24 months

  2. Immune biomarkers

    A secretory antibody immunoglobulins A and secretory immunoglobulins A ( IgA ,S-IgA) that plays an integral role in the maintenance of mucosal homeostasis and is associated with increased risk of infection will be measured.

    Measured: 12 to 24 months

  3. Anthropometric biomarkers

    Anthropometrics - Body Mass Index (BMI)

    Measured: 12 to 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Sleep Disorder, run by Yale University 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 1 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 7 Dec 2021. 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. 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?

Sleep monitoring (time frame: 9 days). The study lists 4 primary outcomes in all. 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 7 Dec 2021.
