Material Hardships and Infant and Toddler Sleep Duration in Low-Income Hispanic Families.

Objective: To assess relationships between material hardships, shortened sleep duration, and suboptimal sleep practices across infancy and toddlerhood in low-income Hispanic families.

Methods: We analyzed longitudinal data of 451 low-income Hispanic mother-child pairs from a child obesity prevention trial. During infancy and toddlerhood, we used adjusted linear regression to assess associations between material hardship (financial difficulty, food insecurity, housing disrepair, and multiple hardships), sleep duration (24-hour, night), and the number of suboptimal sleep practices (eg, later bedtime, co-sleeping).
