Post-neonatal mortality by rurality and Indigenous status in Queensland

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 7-8 2006
Michael Coory
Aim: To compare post-neonatal mortality among urban and rural Indigenous babies in Queensland. Methods: Registrations of deaths at ages 28 days to 12 months were linked to routine data from the Queensland Perinatal Data Collection. Results: Indigenous babies were 2.52 times more likely to die during the post-neonatal period than non-Indigenous babies (95% confidence interval: 1.99, 3.20). The differential remained when urban and rural areas were examined separately: the differential was 2.53 (1.81, 3.54) in urban areas and 2.26 (1.58, 3.23) in rural areas. Conclusion: The key demographic variable that determines post-neonatal mortality in Queensland is Indigenous status, not rurality. This has important policy implications because it means that interventions to reduce the disparity in mortality between Indigenous and non-Indigenous babies should be delivered in urban as well as rural areas. Better routine data are needed and in particular clinical classification of deaths, so that interventions can be monitored and avoidable factors identified. [source]


The Asian birth outcome gap

Summary Asians are often considered a single group in epidemiological research. This study examines the extent of differences in maternal risks and birth outcomes for six Asian subgroups. Using linked birth/infant death certificate data from the State of California for the years 1992,97, we assessed maternal socio-economic risks and their effect on birthweight, preterm delivery (PTD), neonatal, post-neonatal and infant mortality for Filipino (87 120), Chinese (67 228), Vietnamese (45 237), Korean (23 431), Cambodian/Laotian (21 239) and Japanese (18 276) live singleton births. The analysis also included information about non-Hispanic whites and non-Hispanic blacks in order to give a sense of the magnitude of risks among Asians. Logistic regression models explored the effect of maternal risk factors and PTD on Asian subgroup differences in neonatal and post-neonatal mortality, using Japanese as the reference group. Across Asian subgroups, the differences ranged from 2.5- to 135-fold for maternal risks, and 2.2-fold for infant mortality rate. PTD was an important contributor to neonatal mortality differences. Maternal risk factors contributed to the disparities in post-neonatal mortality. Significant differences in perinatal health across Asian subgroups deserve ethnicity-specific interventions addressing PTD, teen pregnancy, maternal education, parity and access to prenatal care.

Gestational age- and birthweight-specific declines in infant mortality in Canada, 1985,94

We studied infant mortality rates in Canada within specific gestational age and birthweight categories after using probabilistic techniques to link information in Statistics Canada's live births data base (1985,94) with that in the death data base (1985,95). Gestational age- and birthweight-specific mortality rates in 1992,94 were contrasted with those in 1985,87 with changes expressed in terms of relative risks with 95% confidence intervals [CI]. Statistically significant reductions in infant mortality were observed beginning at 24,25 weeks of gestation and extended across the gestational age range to post-term births. Crude infant mortality rates, infant mortality rates among those 500 g and among those 1000 g decreased by 22%, 25% and 26%, respectively, from 1985,87 to 1992,94. The magnitude of the reductions in infant mortality rates ranged from 14%[95% CI 7, 21%] at 24,25 weeks of gestation to 40%[95% CI 31, 47%] at 28,31 weeks. Almost all reductions in gestational age- and birthweight-specific infant mortality between 1985,87 and 1992,94 were due to approximately equal reductions in neonatal and post-neonatal mortality. Live births 42 weeks of gestation did not follow this rule; post-neonatal mortality rates among such live births decreased significantly by 51%[95% CI 26, 68%], although neonatal mortality rates showed no significant change. The mortality reductions observed across the gestational age and birthweight range are probably a consequence of specific clinical interventions complementing improvements in fetal growth. Temporal changes in the outcome of post-term pregnancies need to be carefully examined, especially in relation to recent changes in the obstetric management of such pregnancies. [source]
