Appetitive traits were assessed at 3-4 months of age. EBF duration, feeding practices, sex, maternal age and education,…

Effortful control, the ability to suppress a dominant response over a subdominant one, is a fundamental aspect of self-regulation. It has been observed that higher levels of parenting stress are associated with lower levels of effortful control in children. Perceived social support, an important factor in reducing parenting stress, may act as a…

Autism Spectrum Disorders (ASD) prevalence has risen globally, with regional variation and sociodemographic disparities affecting diagnosis and intervention. This study examines ASD trends from 1990 to 2018 in California (CA), focusing on sociodemographic factors that may inform policy/interventions. Using CA Department of Public Health birth…

Background: Despite the ability of cochlear implants (CIs) to provide children with access to speech, there is considerable variability in spoken language outcomes. Research aimed at identifying factors influencing speech production accuracy is needed. Aims: To characterize the consonant production accuracy of children with cochlear implants…

Despite growing interest in placental epigenetics, the combined impact of prenatal stress and socioeconomic status on placental methylation is still largely understudied. We conducted a study to examine the associations of prenatal stress and socioeconomic factors (household income, Hollingshead socioeconomic index) with placental methylation.…
