Time-dependent association between prenatal hair glucocorticoid levels and child behavior problems.

Key Points

• This study aims to investigate the association between prenatal hair glucocorticoid levels and behavioral problems in children over time.
• Analyzed prenatal hair samples for glucocorticoid concentrations
• Assessed child behavior problems at multiple developmental stages
• Utilized time-dependent modeling techniques for data analysis
• Identified significant associations between glucocorticoid levels and behavioral problems
• Found that timing of glucocorticoid measurement influenced the strength of the association
• Highlighted the importance of prenatal stress in child development
