Morbidity and death due to child abuse in New Zealand.

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).
