Apparent life-threatening events during infancy: a follow-up study of subsequent growth and development
1University of Wisconsin-Madison, School of Nursing 53792.
Insights
Infants experiencing apparent life-threatening events (ALTE) showed that perinatal factors, birth status, and recurrent apnea impact growth and development. The home environment also influences developmental outcomes in these infants.
Area of Science:
- Pediatrics
- Developmental Psychology
- Neonatology
Background:
- Apparent life-threatening events (ALTE) in infants, often involving apnea, necessitate further investigation into long-term outcomes.
- Understanding factors influencing infant growth and development post-ALTE is crucial for early intervention.
Purpose of the Study:
- To explore relationships between perinatal characteristics, birth status, recurrent apnea, and home environment ratings.
- To determine how these factors relate to infant growth and developmental outcomes at 10–14 months.
Main Methods:
- Follow-up study of 51 infants with a history of ALTE.
- Home visits for assessments and retrospective review of medical records.
- Utilized the Home Observation for Measurement of the Environment (HOME) Scale.
Main Results:
- Perinatal characteristics, birth status, and recurrent apnea were significant correlates of both growth and developmental outcomes.
- The HOME Scale scores, particularly provision of play materials, positively related to developmental outcomes.
- Hierarchical regression confirmed that gestational age, complications, apnea, and HOME subscale 4 predicted mental and psychomotor development.
Conclusions:
- Perinatal factors, infant's medical history (apnea), and the home environment are key determinants of infant development after an ALTE.
- Further longitudinal research is needed to clarify the direct or mediated impact of apnea on infant outcomes and caregiving dynamics.
Abstract:
This research was an exploratory follow-up study of 51 infants who had experienced an "apparent life-threatening event" (ALTE) characterized by apnea and subsequent home cardiorespiratory monitoring. The purpose was to (1) describe relationships among perinatal characteristics, birth status, recurrent apnea, and ratings of the home environment, and (2) relate these measures to infant growth and developmental outcomes. The method included home visits and assessments of infant outcomes at 10 to 14 months, followed by retrospective review of obstetric and infant medical records. Perinatal characteristics, birth status, and recurrent apnea were interrelated correlates of both growth and developmental outcomes. The ratings of the home environment (HOME [Home Observation for Measurement of the Environment] Scale) were related to developmental outcomes and to a lesser extent to physical growth status. Hierarchical regression analysis entering gestational age, obstetric and postnatal complications, apnea, and HOME subscale 4 (provision of appropriate play materials) significantly enhanced the predictability of mental and psychomotor development. Future longitudinal research is necessary to explore whether the association between apnea and specific infant outcomes attenuates over time and whether the relationship is direct or mediated by parental perception of infant vulnerability and altered caregiving style.
