Outcomes of interest

The main outcome of interest for this review will be preterm birth among Pacific Islanders. Prevalence of and risk factors associated with preterm birth in those studies will be summarised. Relevant health outcomes of preterm infants will be classified as ‘short-term’ (diagnoses during the initial birth hospitalisation) or ‘long-term’ (symptoms or diagnoses after the initial birth hospitalisation) outcomes.^{34 35} Health outcomes of mothers who experienced preterm birth will also be examined. Potential neonatal outcomes will include, but will not be limited to, birth weight, fetal growth restriction, fetal death, stillbirths, neonatal intensive care unit admission, neonatal and infant mortality, congenital abnormalities and long-term health effects. Maternal health outcomes included in our study will be, but will not be limited to, maternal mood effects, and physical health outcomes if there is any report. Existing interventions that have been implemented on preterm Pacific Islander infants will also be reviewed. Studies retrospectively examining changes in healthcare management or practices will not be included in this review; studies describing outcomes of multiple births will also be excluded.
