Lifetable analysis was used to combine the risk of each type of perinatal mortality and calculate the cumulative risk of perinatal mortality, termed the perinatal risk index (PRI). Rates of antepartum and intrapartum stillbirth and neonatal death, as well as the PRI, were examined for each gestational week at term by non\u2010Aboriginal and Aboriginal ethnicity. For non\u2010Aboriginal women, rates were also examined by time\u2010period (pre\u2010 vs. post\u2010WA Preterm Birth Prevention Initiative (the Initiative) rollout), primiparity, and obstetric risk.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 332,084 singleton term births, including 60 perinatal deaths to Aboriginal mothers (3.2 deaths per 1000 births to Aboriginal mothers) and 399 perinatal deaths to non\u2010Aboriginal mothers (1.3 deaths per 1000 births to non\u2010Aboriginal mothers). For non\u2010Aboriginal women, the PRI was at its lowest (PRI 0.80, 95% CI 0.61, 1.00) at 39\u2009weeks gestation. For Aboriginal women, it was at its lowest at 38\u2009weeks (PRI 2.43, 95% CI 0.48, 4.39) with similar risk at 39\u2009weeks (PRI 2.68, 95% CI 1.22, 4.14). The PRI increased steadily after 39\u2009weeks gestation. The risk of perinatal mortality was higher among Aboriginal women.
