Summary
Neonatal intensive care unit (NICU) stress in preterm infants is linked to later behavioral and neurodevelopmental outcomes. Reducing NICU stress and providing developmental support are crucial for improving long-term health.
Area of Science:
- Neonatal intensive care
- Developmental psychology
- Pediatric neurology
Background:
- Preterm infants experience significant stress in the NICU.
- NICU stressors may impact critical brain development.
- This exposure can lead to long-term neurodevelopmental effects.
Purpose of the Study:
- To investigate the association between NICU stressor exposure and neurodevelopmental outcomes at four years of age in preterm infants.
- To analyze relationships between stressor scores and childhood behavior and development.
Main Methods:
- The Neonatal Infant Stress Scale (NISS) measured daily stress events in 83 preterm infants during the first six weeks.
- Twenty-five children were assessed at four years using the Child Behavior Checklist (CBCL) and Battelle Developmental Index-Screening Test (BDI-2 ST).
Main Results:
- Cumulative NISS scores correlated with CBCL and BDI-2 ST in unadjusted models.
- Gestational age and time to enteral feeding were associated with CBCL scores.
- Score for Neonatal Physiology with Perinatal Extension (SNAPPE-II) was associated with BDI-2 ST scales.
- Hierarchical regressions indicated relationships between NISS and both scales, influenced by GA, SNAPPE-II, and feeding duration.
Conclusions:
- The quantity and type of neonatal stress may influence neurodevelopmental outcomes at four years.
- Larger studies are needed to confirm these findings.
- Clinical practice should focus on minimizing NICU stress and offering developmental support to these children.

01:30Socioemotional Development during Infancy
28
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

01:30Stress and Mental Health
68
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

01:27Introduction to Stress and Lifestyle
62
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

23
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.

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,...

01:20Psychological Responses to Stress
34
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...
