Insights
Prenatal stress did not affect newborn nail hormone levels. However, intrauterine growth restriction (IUGR) was linked to lower dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) concentrations in infant nails.
Area of Science:
- Endocrinology
- Developmental Biology
- Neonatal Medicine
Background:
- Prenatal stress and intrauterine growth restriction (IUGR) can impact fetal development.
- Hormone levels in newborns may reflect intrauterine conditions.
- Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are key fetal hormones.
Purpose of the Study:
- To investigate the association between prenatal stress and IUGR with DHEA and DHEAS concentrations in newborn nails.
- To explore nail DHEA and DHEAS as potential biomarkers for intrauterine conditions.
Main Methods:
- Nail samples were collected from 56 newborns.
- DHEA and DHEAS concentrations were measured using liquid chromatography/tandem mass spectrometry.
- Prenatal stress was assessed using the Prenatal Distress Questionnaire and Life Experience Survey.
Main Results:
- Prenatal stress was not correlated with infant nail DHEA or DHEAS levels.
- Infants with IUGR exhibited decreased concentrations of both DHEA and DHEAS in their nails.
- Nail DHEAS concentration positively correlated with gestational age.
Conclusions:
- Prenatal stress does not appear to influence DHEA or DHEAS levels in newborn nails.
- IUGR is associated with reduced DHEA and DHEAS concentrations, suggesting altered fetal hormone activity.
- Nail DHEAS levels may serve as an indicator of gestational age and intrauterine environment, offering insights into fetal programming.
Abstract:
This study assesses the impact of prenatal stress and intrauterine growth restriction (IUGR) on the dehydroepiandrosterone (DHEA) and dehydroepiandrosteronesulfate (DHEAS) concentrations in nails of newborns. Nail samples were gained from 56 newborn infants. The concentration of DHEA and DHEAS was measured by liquid chromatography/tandem mass spectrometry. Prenatal stress was assessed by the Prenatal Distress Questionnaire and by the Life Experience Survey. Prenatal stress was not associated with infant nail DHEA or DHEAS concentrations. The concentration of DHEA and DHEAS was decreased in infants with IUGR (DHEA: p = 0.037, DHEAS p < 0.01). Nail-DHEAS increased with gestational age (p < 0.01). In this study prenatal life event stress or pregnancy specific stress do not correlate with higher DHEA or DHEAS concentrations in nails of newborns. Concentration of DHEAS is rather affected by length of gestation. Our approach is an easily applicable method to assess intrauterine life with the potential to give insights in the activity of fetal hormone systems and mechanism underlying fetal programming.
