Abstract:
Background: Under Every Newborn Action Plan (ENAP), stillbirth rate in every country should be reduced by 12 or fewer per 1000 total births by 2030. The aims of this study were to determine stillbirth rate at national and subnational levels and to investigate its associated risk factors in Iran. Methods: Using all data from Iranian Maternal and Neonatal Network (IMaN), we calculated stillbirth rate of Iran from 2014-2016. This network registers information of almost all births across the country. The logistic regression was used to estimate the adjusted odds ratio (aOR) with 95% confidence intervals (CIs) for stillbirth. Results: In 2014, still birth rate was 7.40 per 1000 births. In 2015 and 2016, stillbirth rates were 7.22 per 1000 births and 7.63 per 1000 births, respectively. The most important related factors of stillbirth were preterm birth (aOR= 62.53, 95% CI; 60.77-64.34), sexual ambiguity (aOR= 14.51, 95% CI; 12.76-16.50), and post term birth (aOR= 3.31, 95% CI; 2.66-4.13). Conclusion: Under Every Newborn Action Plan (ENAP), stillbirth rate in every country should be reduced by 12 or fewer per 1000 total births by 2030. Iran has achieved stillbirth target of ENAP at national level. It is important for the health care system to establish and improve specific and focused policies, interventions, and programs for achieving this target even in the most deprived areas.
