AI Article Synopsis
- - We studied how exposure to different microbes at birth affects the behavior and temperament of children at ages 1, 2, and 3, using data from the Kuopio Birth Cohort Study and various behavioral questionnaires.
- - Microbial samples from babies’ mouths were analyzed to determine their diversity, with a focus on comparing those born with and without antibiotic exposure during delivery.
- - While no strong associations were confirmed after strict statistical corrections, initial findings suggested a possible link between microbial diversity and behaviors like surgency, especially for children exposed to antibiotics at birth.
Article Abstract
We investigated cross-sectional and longitudinal associations between neonate microbial exposure and emerging behavioral temperament measures at the ages of 1, 2, and 3 years. Infants and mothers () were extracted from the Kuopio Birth Cohort Study. Temperament was assessed using the Infant Behavioral and Early Childhood Behavioral Questionnaires. Microbial samples were collected from oral cavity at birth and the bacterial profiles were assessed using 16S rRNA gene sequencing. Microbial diversity was characterized using alpha and beta diversity metrics. Analyses were performed for the most abundant genera. The sample was analyzed as a whole, as well as divided into subgroups representing no antibiotic use during birth () and those with antibiotic use during birth (). No significant associations were observed between microbial profiles and behavioral measures after Bonferroni corrections. Nevertheless, our pre-correction results indicated an association between increased behavioral temperament surgency in the first year and beta diversity (high abundance of , and , low abundance of ) in the antibiotic use group. Additionally, pre-corrections, a high relative abundance of was associated with increased surgency through years 1, 2, and 3 in the no antibiotics group, prompting consideration into a possible link between antibiotic use and emerging behavioral temperament.

Humans are curious. Especially children are known for their drive to explore and learn, which is crucial for developing in and navigating through our complex world. Naturally, some children may be more curious than others, leading to differences in how they structure their own learning experiences, subsequently impacting their developmental trajectories.

Research Findings: Temperament, which can be assessed as early as three months, is associated with school readiness and later academic achievement in children born full term. Although children born preterm demonstrate a dysregulated temperament and are at significant risk for lower school readiness, we found no studies investigating whether early temperament is associated with school readiness in this at-risk population. Investigating whether temperament is a precursor of academic risk in preterm children can facilitate early identification and possible intervention efforts.

Parental cognitions, stress, depression, and infant regulatory challenges might reinforce each other in the early parent-infant relationship. A transactional model was used as a framework to investigate these relationships. Two hundred and twenty pregnant women and their partners were recruited during pregnancy and followed 7 months postnatally in the NorBaby study in Norway.

Background: Identification of prodromal indicators of autism in infancy has the potential to identify behaviors relevant to early autism screening.
Methods: We report on data from a prospective general population birth cohort with maternal reported measures at 9 and 12 months: the Survey of Well-Being of Young Children (SWYC; general developmental surveillance) and the First Year Inventory-Lite v3.1b (FYI-Lite; autism specific parent report research tool).

Background: Disruptive Mood Dysregulation Disorder (DMDD), characterized by severe irritability and temper outbursts, is a relatively new diagnosis included in the DSM-5. The study aimed to investigate the clinical characteristics, temperament, comorbidities, medication use, and sleep quality of children and adolescents diagnosed with DMDD and compare them with Major Depressive Disorder (MDD).
Methods: A total of 233 participants (DMDD: = 106; MDD: = 127) were assessed using the K-SADS-PL.
