The provided texts discuss the significant impact of prenatal environmental factors, particularly maternal stress, on a child's neurodevelopment and long-term health outcomes. Several sources highlight the "fetal origins hypothesis", which posits that experiences during gestation can lead to lasting effects, from infancy to adulthood, affecting cognitive, emotional, and physical well-being. This influence is often linked to epigenetic changes, where the prenatal environment can alter gene expression without changing the underlying DNA. Furthermore, the texts examine how various stressors, including natural disasters, socioeconomic hardship, and even occupational exposure to traumatic imagery, can contribute to these adverse outcomes, emphasizing the importance of supporting maternal mental health during pregnancy.Sources:
