Insights
Child abuse under-diagnosis and racial bias were explored in New Zealand data. Maori and Samoan children were more likely to be coded for child abuse, indicating potential bias in reporting and diagnosis.
Area of Science:
- Public Health
- Pediatrics
- Forensic Medicine
Background:
- Child abuse is a significant public health concern with potential disparities in identification.
- Accurate coding of child abuse morbidity and mortality data is crucial for understanding its prevalence and impact.
- Previous research suggests potential racial biases in healthcare data, necessitating further investigation in child abuse contexts.
Purpose of the Study:
- To investigate the extent of under-diagnosis of child abuse.
- To examine racial bias in the coding of child abuse morbidity and mortality data in New Zealand.
- To identify disparities in the classification of child abuse based on race.
Main Methods:
- Analysis of computerized files for child fatalities (1978-1987) and hospital discharges (1988) involving intentional injuries in children aged 16 and under.
- Review of data for evidence of physical abuse and sexual abuse, and examination of assigned diagnostic codes (E-code E967, N-code 995.5).
- Statistical analysis to assess the association between child abuse diagnosis, race, age, and sex, controlling for relevant variables.
Main Results:
- Among 92 child fatalities, only 21 of 68 deaths attributed to abuse were coded as such, indicating significant under-diagnosis.
- Maori and Samoan child abuse fatalities were more likely to be coded as "child battering and other maltreatment" (E967) compared to other ethnic groups (p=0.04).
- Hospitalization data showed significant associations between race and the coding of physical abuse (p=0.05) and child maltreatment syndrome (N-code 995.5) (p=0.002 for age, p=0.004 for sex).
Conclusions:
- Under-diagnosis of child abuse is prevalent in New Zealand mortality data.
- Racial bias exists in the coding of child abuse, with Maori and Samoan children disproportionately represented in specific abuse categories.
- These findings highlight the need for improved data collection, coding practices, and cultural competency in child abuse identification and reporting to address systemic biases.
Abstract:
The purpose of this study was to explore under-diagnosis and racial bias among child abuse morbidity and mortality data from New Zealand. Computerized files of all intentional injury fatalities among children 16 years of age and under for 1978-87, and all hospital discharges for intentionally injured children 16 and under for 1988, were analyzed for evidence of physical abuse and sexual abuse. Among the 92 fatalities, only 21 of 68 deaths due to physical and/or sexual abuse were so coded. In both the mortality and the morbidity data, there was an association between the diagnosis of child abuse and race. In the case of fatalities, Maori and Samoan abuse victims were more likely to be assigned an E-code of E967 ("child battering and other maltreatment") than were "others" (p = 0.04), controlling for sex. In the case of hospitalizations, the association between E967 and whether or not the victim was European was significant for physical abuse only (p = 0.05). Assignment of N-code = 995.5 ("child maltreatment syndrome") as the reason for admission was significantly associated with race for those cases considered by us to have been abused, controlling for age (p = 0.002) or sex (p = 0.004).
