Impact of Sleep Duration on Immune Balance in Urban Children With Asthma (AIMS)

September 19, 2025 updated by: Rhode Island Hospital
Urban children with asthma are at high risk for short sleep, due to an environment that jeopardizes both sleep and asthma management. Further, urban children with asthma suffer from altered immune balance, a key biological process contributing to individual differences in asthma morbidity and sleep health. In the proposed research, the researchers will examine the effects of shortened and recovery sleep on immune balance and associated changes in lung function in urban children with allergic asthma through an experimental design.

Study Overview

Detailed Description

Urban children with asthma are at high risk for short sleep, due to an environment that jeopardizes sleep and asthma management. Further, this group suffers from altered immune balance, a key biological process contributing to individual differences in asthma morbidity and sleep health. Allergic asthma is a chronic inflammatory disorder driven primarily by disturbed T helper 1 (Th1)/ 2 (Th2) cytokine balance marked by Th2 cytokine (IL-4, IL-5 and/or IL-13) predominance. Experimental findings in healthy adults show that shortened sleep increases inflammatory cytokine (e.g., IL-6) and certain Th2 cytokine levels and that recovery sleep following sleep restriction promotes a return to immune balance. Whether sleep duration plays a key role in immune function and associated asthma activity in urban children with asthma remains a scientific gap. The researchers use an experimental design that targets sleep duration, because (1) the urban environment and asthma symptoms interact to shorten sleep, (2) sleep duration is a modifiable behavior overlooked in clinical care of urban children with asthma, and (3) experimental data are critical to test a causal link for sleep duration as a mechanism underlying immune balance and asthma.

The research team will enroll urban children (N=204; ages 7-11 years) with persistent allergic asthma and adequate sleep duration (9-11 h) who will complete a 4-week within-subjects protocol that includes 3 scheduled experimental sleep conditions: (1) 1 week stabilized sleep (individualized; 9-11 h time in bed), (2) 1 week shortened sleep (1.5 h decrease in time in bed), and (3) 2 weeks recovery sleep (1.5 h increase in time in bed). Sleep duration (actigraphy) and lung function (home spirometry) will be monitored daily and assess immune biomarkers weekly and at the midpoint of shortened sleep. To control time-in-study effects, 1/3 of the sample will receive only the stabilized sleep schedule across the 4-week protocol. In this project, the researchers will study only urban children with allergic asthma who obtain sufficient sleep (9-11 h, within national guidelines). The shortened sleep protocol will model the sleep loss that urban children with asthma can experience due to asthma and/or urban context. Additionally, the recovery sleep protocol simulates a sleep optimization intervention following shortened sleep in a well-controlled approach.

The first aim of the study is to examine the effects of shortened sleep on immune balance [e.g., Th1 (Interferon-IFN gamma)/Th2 (Interleukin-IL-4, IL-5, IL-13)R and plasma IL-6 levels]. The second aim involves determining the effects of recovery sleep on immune balance. The third aim involves examining the extent to which changes in immune balance are associated with changes in asthma-related lung function (changes in FEV1) under conditions of shortened and recovery sleep. Results from this study ultimately will support the development feasible, ecologically valid, and clinically meaningful interventions to optimize sleep duration, immune balance, and asthma in this at-risk group.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Shortened Sleep
In this 4-week sleep protocol, children in this experimental condition follow a Stabilized Sleep schedule (i.e., their usual bed time) during weeks 1, 3 and 4. During week 2, they follow a Shortened Sleep schedule, during which they go to bed 90 later than is typical.
In this experimental condition, children go to bed 90 minutes later than their typical bedtime during Week 2 of the 4-week protocol.
Active Comparator: Usual Sleep Schedule
In this control arm of the 4-week sleep protocol, children follow the Stabilized Sleep schedule for all 4 weeks.
In this control condition, children go to bed at their usual time throughout the 4-week protocol.

IPD Plan Description

Following the NIH data sharing policy (2015), within one year of completion of the study and dissemination of primary study results, public-use analysis datasets will be made available to the public, along with the final version of the study protocol, data dictionaries and brief instructions. De-identification for the analysis data sets will follow published guidelines for "limited access data sets" funded by NHLBI (Geller et al., 2004).

IPD Sharing Time Frame

Data will become available within one year of completion of the study and dissemination of primary study results and will be available for 10 years following the completion of the study.

IPD Sharing Access Criteria

Once data become available, researchers requesting the data would follow the published "Project AIMS" data request procedures (available from the PI or designate). We will make data available to potential users only under an NIH-approved data sharing agreement that provides for 1) a commitment to using the dta only for research purposes and not to identify any individual participant in any way; 2) a commitment to securing the data using appropriate information security this is compliant with the most current federal guidelines that are outlined by our information security protocol; and 3) a commitment to destroying or returning the data after completion of analyses.
