Insights
Long-term pain coping in adolescents born preterm is minimally affected by early-life factors. Higher IQ is linked to adaptive pain coping strategies, while maladaptive strategies are less common.
Area of Science:
- Developmental Psychology
- Neonatal Medicine
- Pain Management
Background:
- Limited data exists on long-term pain coping in individuals born preterm.
- Understanding these consequences is crucial for improving long-term health outcomes.
Purpose of the Study:
- To investigate the impact of gestational age, birth weight, and neonatal disease severity on pain coping styles in adolescents born preterm or with low birth weight.
- To identify predictors of pain coping strategies in this population.
Main Methods:
- An observational, longitudinal study (Project On Preterm and SGA-infants, POPS-19) followed 537 adolescents born before 32 weeks gestation or weighing less than 1500g.
- Pain coping strategies, effectiveness, controllability, emotional reactions, and IQ were assessed at age 19 using questionnaires and cognitive tests.
Main Results:
- Neonatal factors like length of stay, sepsis, and necrotizing enterocolitis showed no significant correlation with pain coping styles.
- Higher IQ was associated with adaptive pain coping (approach) and negatively correlated with emotion-focused avoidance.
- Intraventricular hemorrhage (IVH) was positively correlated with emotion-focused avoidance, while respiratory support was negatively correlated.
Conclusions:
- Early neonatal characteristics and disease severity have a limited influence on adolescent pain coping.
- Intellectual quotient (IQ) is a significant factor, with higher IQ associated with more adaptive pain coping strategies.
Background:
Data on long-term consequences of preterm birth on pain coping later in life are limited.
Aim:
To assess whether gestational age, birth weight and neonatal disease severity have effect on pain coping style in adolescents born preterm or with low birth weight.
Study Design:
Observational, longitudinal study (Project On Preterm and SGA-infants, POPS-19).
Subjects:
We analyzed data of 537 adolescents at the age of 19 years, who were born at a gestational age <32 weeks or with a birth weight <1500g.
Outcome Measures:
Participants completed the pain coping questionnaire (PCQ) that assesses pain coping strategies in three higher-order factors: approach ("to deal with pain"), problem-focused avoidance ("to disengage from pain") and emotion-focused avoidance ("expression of pain"). Furthermore, their pain coping effectiveness, pain controllability and emotional reactions to pain were assessed. All participants completed an IQ test.
Results:
Univariate analysis showed no significant correlation between length of stay, sepsis and necrotizing enterocolitis and any of the higher-order factors. Approach was only correlated with IQ. Problem-focused avoidance was, in the multiple regression analysis (including gestational age, IVH and IQ), only correlated with IQ. For emotion-focused avoidance (including birth weight, SGA, IVH, respiratory support and IQ) three independent predictors remained: IVH was positively correlated, while respiratory support and IQ were negatively correlated with emotion-focused avoidance.
Conclusions:
Early neonatal characteristics and neonatal disease severity have limited effect on pain coping style in adolescence. Higher IQ was associated with the use of adaptive coping strategies, while maladaptive strategies were used less.
