Perinatal stress and early life programming of lung structure and function

Area of Science:

• Environmental Health
• Developmental Biology
• Immunology

Background:

• Prenatal and postnatal exposure to environmental toxins can disrupt lung development and maturation.
• Inflammatory responses and neuroendocrine (hypothalamic-pituitary-adrenal axis) and autonomic nervous system (ANS) function are critical in lung health.
• Early life disruptions can have long-lasting effects on respiratory structure and function, impacting public health.

Purpose of the Study:

• To review evidence linking psychological factors to physiological alterations affecting childhood lung function.
• To identify gaps in understanding the complex interplay between early life exposures, physiological systems, and lung health.

Main Methods:

• Literature review of studies examining environmental toxins, psychological factors, immune responses, neuroendocrine function (HPA axis), and ANS function in relation to childhood lung function.

Main Results:

• Environmental toxins and psychological stress can alter immune responses and HPA axis/ANS function during critical developmental periods.
• These alterations contribute to airway inflammation and changes in lung structure and function.
• Early life impacts can persist into adulthood, increasing the long-term public health burden.

Conclusions:

• Psychological factors, alongside environmental toxins, play a significant role in childhood lung development and function.
• Interactions between the immune, neuroendocrine, and autonomic nervous systems are key mediators of these effects.
• Further research is needed to fully elucidate these complex relationships and inform interventions.
