Is intrauterine growth retardation a risk factor for child abuse?
Insights
Infants with intrauterine growth retardation (IUGR) show a decreased risk of child abuse. This case-control study found no increased risk, suggesting IUGR may be protective against physical abuse.
Area of Science:
- Pediatrics
- Child Abuse Research
- Neonatology
Background:
- Intrauterine growth retardation (IUGR) is a significant concern in perinatal health.
- Previous research has not definitively established the link between IUGR and the risk of child abuse.
- Understanding risk factors for child abuse is crucial for developing targeted interventions.
Purpose of the Study:
- To investigate the association between intrauterine growth retardation (IUGR) and the risk of physical child abuse.
- To determine if infants diagnosed with IUGR are more or less susceptible to abuse.
- To provide evidence-based insights into the relationship between fetal growth and child maltreatment.
Main Methods:
- A case-control study design was employed, matching abused infants (cases) with non-abused infants (controls).
- Infants were classified with IUGR based on ponderal index or birth weight below the tenth percentile for gestational age.
- Matching criteria included age, gender, maternal race, payment method, and healthcare provider at birth.
Main Results:
- The study identified 117 case-control pairs meeting the criteria for IUGR.
- Matched odds ratios for all four IUGR definitions were less than one, indicating a decreased risk of abuse.
- A low ponderal index (Kansas City standard) showed a matched odds ratio of 0.4 (95% CI 0.19, 0.83), with no significant confounding by maternal age.
Conclusions:
- Infants with intrauterine growth retardation (IUGR) are not at an increased risk of physical abuse.
- Findings suggest that IUGR may be associated with a decreased risk of child abuse.
- This research challenges previous assumptions and highlights a potentially protective factor in IUGR.
Abstract:
A case-control study was conducted to determine whether infants with intrauterine growth retardation are at an increased risk of child abuse. Case children were those who had been born at Yale-New Haven Hospital and were reported to the hospital's child abuse committee because they had been physically abused. For each case, one control child was chosen from the hospital's log of births and matched to the case child by age, gender, race of the mother, method of payment for the hospitalization, and the provider of the child's health care at the time of birth. Infants were defined as having intrauterine growth retardation if they had either a ponderal index or a birth weight that was less than the tenth percentile for gestational age using the Kansas City or Denver growth standards. We identified 117 case-control pairs that met those criteria. The matched odds ratios for each of the four definitions of intrauterine growth retardation were less than one, indicating that infants with intrauterine growth retardation are at a decreased risk of abuse. The matched odds ratio for a low ponderal index according to the Kansas City standard was 0.4 (95% confidence interval 0.19, 0.83). This result was not affected by such possible confounding factors as the mother's age. We conclude that infants with intrauterine growth retardation are not at an increased risk and may be at a decreased risk of physical abuse.
