Pre-school children of amphetamine-addicted mothers. I. Somatic and psychomotor development
Insights
Children exposed to amphetamine during pregnancy showed normal physical growth but had lower IQ scores by age 4. More behavioral problems were observed in children with mothers still struggling with drug addiction.
Area of Science:
- Pediatric Health
- Neurodevelopmental Disorders
- Pharmacology
Background:
- Maternal substance use during pregnancy poses risks to child development.
- Amphetamine exposure in utero may impact neurocognitive and emotional outcomes.
- Longitudinal data on children exposed to amphetamines are crucial for understanding developmental trajectories.
Purpose of the Study:
- To assess the long-term somatic growth and general health of children exposed to amphetamine in utero.
- To evaluate the neurocognitive development, specifically IQ, of these children at age 4.
- To examine the psychological adaptation and emotional wellbeing in relation to maternal drug addiction status.
Main Methods:
- Prospective cohort study following 65 children from birth.
- Comparison with an unselected Swedish population for somatic growth and general health.
- Terman Merrill intelligence testing for neurocognitive assessment.
- Psychological assessment of child adaptation and emotional wellbeing.
Main Results:
- No significant differences in somatic growth or general health compared to the control group.
- Children exposed to amphetamine had a significantly lower mean IQ (103) than the control group (110).
- A higher prevalence of behavioral disturbances and 'problem children' was noted in those with mothers still addicted to drugs.
Conclusions:
- Prenatal amphetamine exposure may be associated with reduced cognitive function (IQ) in early childhood.
- Continued maternal drug addiction exacerbates negative psychological and emotional outcomes in exposed children.
- While physical development may be unaffected, neurodevelopmental and behavioral monitoring is essential for children with prenatal amphetamine exposure.
Abstract:
Sixty-five children whose mothers took amphetamine during pregnancy have been followed prospectively since birth. At 4 years of age their somatic growth and general health did not differ from that of another unselected Swedish population of the same age examined at the Child Health Centre. Developmental screening by the Terman Merrill method showed that the group as a whole had a significantly lower IQ (103) than a sampled Swedish group (110). The psychological assessment of the child's adaptation and emotional wellbeing showed that there were more disturbed children or "problem children" in the group that had lived partly or all the time with a mother who was still addicted to drugs.
