Summary
Prenatal depression increases risks for premature delivery and low birthweight. Maternal cortisol levels during pregnancy may mediate these adverse fetal growth outcomes.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Mental Health
- Endocrinology
Background:
- Prenatal depression is a significant concern impacting maternal and fetal well-being.
- Understanding the physiological mechanisms linking maternal depression to fetal development is crucial.
Purpose of the Study:
- To investigate the association between prenatal depression and fetal growth restriction.
- To explore the role of maternal cortisol levels as a mediator in this relationship.
Main Methods:
- A cohort of 40 depressed and 40 non-depressed pregnant women were assessed.
- Midgestation fetal weight, urine cortisol, and birth outcomes (birthweight, gestational age) were collected.
- Fetal growth rates were calculated using estimated fetal weight and birthweight data.
Main Results:
- Depressed women exhibited higher rates of premature delivery (OR=2.61) and low birthweight (OR=4.75).
- Elevated prenatal cortisol levels were observed in depressed women, associated with smaller fetuses and slower growth rates.
- Cortisol levels mediated the link between maternal depression and gestational age/fetal growth rate, explaining 30% and 14% of the variance, respectively.
Conclusions:
- Prenatal depression is linked to adverse perinatal outcomes, including premature delivery and restricted fetal growth.
- Prenatal maternal cortisol levels are implicated as a mediating factor in these adverse outcomes.

Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Nature and Nurture
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Depressive Disorders: Etiology
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.

Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
