Non-fatal injuries among Pacific infants in Auckland: data from the Pacific Islands families first two years of life study.
OBJECTIVE
Child injury is the leading cause of mortality and morbidity in developed countries. While Pacific infant death rates are relatively high in New Zealand, little is known about non-fatal injury rates. We seek to describe maternally reported injury in Pacific infants aged between 0-24 months.


METHODS
A cohort of Pacific infants born during 2000 in Auckland, New Zealand, was followed. Maternal home interviews were conducted at 6 weeks, 12 months and 24 months postpartum and injury events were recalled. Marginal models using generalized estimating equations (GEEs) were used to analysis the longitudinal data.


RESULTS
The inception cohort included 1398 infants at 6 weeks, 1241 infants at 12 months and 1161 infants at 24 months. The age-specific injury incidence per 1000 person-years exposure was estimated at 48 (95% CI: 23, 88) injuries for infants aged 0-6 weeks, 106 (95% CI: 88, 127) injuries for infants aged 7 weeks-12 months and 174 (95% CI: 151, 199) injuries for infants aged 13-24 months. In the multivariable GEE model, older infants (P < 0.001), infants who were male (P = 0.01), born to Pacific Island fathers and non-Pacific Island mothers (P < 0.001), and in higher or unknown income groups (P = 0.01) were significantly more likely to suffer injury events. No significant two-factor interaction with infant age was identified.


CONCLUSIONS
Among Pacific infants, non-fatal injury is common and injury incidence rates are considerably higher than national levels. Male infants and those born into ethnically mixed families, where the father was of Pacific Island ethnicity and the mother was non-Pacific, were at increased relative risk of injury and might benefit from specific injury prevention targeting. However, given the high injury incidence levels found, we advocate that investigation and targeting of culturally appropriate prevention strategies for all Pacific families with young children is required to reduce injury rates for Pacific infants in New Zealand.
