Perinatal outcomes among Indian-born mothers in Australia

Abstract

Objective: To examine the incidence of adverse perinatal outcomes and the risk of adverse perinatal outcomes for Indian-born mothers compared to other mothers living and giving birth in Australia. Design, setting and participants: This retrospective cohort study was designed to investigate all births in Australia in 2012 and those in the Monash Health Birthing Outcomes System (BOS) 2014 to Indian-born mothers in Australia. Data sets were analysed involving descriptive statistics using Statistical Package for Social Sciences (SPSS vs. 23). Results: Indian-born mothers in Australia are at increased risk of induced labour, emergency caesarean section, very preterm birth (20–27 weeks), babies with low to very low birth weight, and low Apgar score (0–2) at 5 min, gestational diabetes, hypothyroidism, iron deficiency anaemia and vitamin B12 deficiencies compared to other mothers giving birth in Australia. This is despite a range of protective factors (25–34 years, married, nonsmokers, and a BMI < 30) that would normally be expected to reduce the risk of adverse perinatal outcomes for mothers giving birth in a developed country. Conclusion: In the absence of many of the recognized maternal risk factors, Indian-born mothers continue to face increased risk of adverse perinatal outcomes, despite access to high quality maternity care in Australia. Recommendations arising from this study include the need for an intervention study to identify maternal risk factors for Indian-born mothers in mid to late pregnancy that contribute to the risk for very preterm birth and low birth weight.
