Sleep, biological stress, and health among toddlers living in socioeconomically disadvantaged homes: A research protocol

ABSTRACT Healthy sleep is important to behavioral, neurobiological, and physiologic health. In older children and adults, stress biomarkers, such as cortisol and C‐reactive protein, increase when they do not practice healthy sleep habits. However, little is known about the relationships among sleep health, stress, and health outcomes among very young children living with socioeconomic adversity, a group that is particularly at risk for poor future health. The NIH‐funded study described in this protocol addresses this scientific gap to improve understanding of these relationships during a critical developmental period in children's lives—toddlerhood. We will use a longitudinal design with repeated measures to prospectively examine the relationships among sleep health, stress, and toddlers’ health from age 12 to 24 months, to address the following aims: i) examine changes in subjective and objective sleep health measures; ii) examine changes in stress biomarkers; iii) examine the cross‐sectional and longitudinal relationships between sleep health measures and stress response; and iv) examine the cross‐sectional and longitudinal relationships between sleep health measures, stress biomarkers, and toddlers’ behavioral health. The sample will include 113 toddlers and their caregivers. We are collecting subjective and objective data on sleep health, multi‐systemic biomarkers of stress, and toddlers’ behavioral health. Generalized linear models will be used in the d...
