Adverse health events within families can harm children's development, including their early literacy. Using data from a longitudinal Wisconsin birth cohort, we estimated the spillover effect of younger siblings' gestational ages on older siblings' kindergarten-level literacy. We sampled 20,014 sibling pairs born during 2007-2010 who took…

Screen time may have a significant association with children's development, yet limited research has examined the specific moderating role of family and child characteristics in this relationship. In this study, we investigated the relationship between screen time exposure and children's development and moderating effects of the family environment…

Children facing adversity are at greater risk of experiencing language difficulties than their peers. This study aims to examine the association between specific maternal responsive behaviours at 24 months and language outcomes at the age of 5 years in a cohort of mothers and children facing adversity. Mother-child dyads (n = 138) facing adversity…

This was a cross-sectional study that aimed to evaluate the association between breastfeeding and motor development of infants at 3-4 months of age in the city of Pelotas, Rio Grande do Sul. The outcome, infant motor development, was evaluated through the Bayley Scale of Infant Development (Bayley III). The prevalence of infants that stopped…

Hierarchical linear modelling was used to explore the effect of changes in maternal sensitivity on attachment over time. Child characteristics of gender, temperament, and developmental status were used as moderating factors. Data from 1,249 mothers and their children from the NICHD Study of Early Child Care and Youth Development when the children…

Gradients across socioeconomic status occur for many children's health and improvement in high-income countries. The objective is to explore infant growth and child development in four developed countries around the socioeconomic landscape. In this paper, Structural Equation Modeling (SEM) enhances the socioeconomic status gradients for the…

Concentrated pockets of under-resourced neighbourhoods and schools exist in urban areas in which there are overwhelming numbers of children labelled 'at-risk.' Structural equation modelling was used to predict the associations between family social capital in kindergarten and third-grade learning and development outcomes for low-socioeconomic…
