Subclaims¶

q2 i? Latent class analysis of parent-reported sleep timing, duration, and behaviors identified two classes, with 87% of children in the earlier, longer, consistent class and 13% in the later, shorter, inconsistent class. → Turnbull Khara L.

q2 · i? · associational · r2

Latent class analysis of parent-reported sleep health from 351 children in publicly-funded PreK programs; the two-class solution was selected as most parsimonious. The article states "87% of children in the sample were classified in Class 1, henceforth, the earlier, longer, consistent sleep health class."

"87% of children in the sample were classified in Class 1, henceforth, the earlier, longer, consistent sleep health class."

• No statistically significant mean differences by sleep health class on literacy, mathematics, or executive functioning after covariate adjustment — related
• A language-based bedtime routine at age 3 predicted longer nighttime sleep duration at age 5 and higher language abilities and receptive vocabulary at age 5 — related
