r). Their main goal was to estimate stillbirth rates for 190 countries. They found that the data from vital registries of 44 countries on 71,442 stillbirths, information from 30 demographic and health surveys from 16 countries containing data on an additional 2,989, and 249 study populations from 103 countries with information on 93,023 stillbirths.
They estimated stillbirth rates based on the model for 128 of the 190 countries, and for the remaining 62 countries they used a correction factor derived from their model to adjust observational data. They then found that stillbirth rates ranged from a relatively low five per 1,000 in wealthy developed nations to 32 per 1,000 in south Asia (accounting for 40% of all stillbirths worldwide), and sub-Saharan Africa (accounting for 28% of all stillbirths.
Half of all stillbirths, 51% they found occurred in four countries Bangladesh, China, India and Pakistan. Rates they found were lower in Eurasia (12.2/1000), Southeast Asia (12.7/1000), and Latin America and the Caribbean (13.2/1000), but were still more than double as in wealthy nations.
They estimated that overall, the number of stillbirths is approximately 3.2 million. They said that the real number could be much higher if not for data limitations, and a conservative approach. They noted that efforts to make accurate estimates of stillbirth rates are hampered by the lack of vital statistics, especially from impoverished nations with high mortality rates.
They concluded by saying that despite efforts to identify the best available data, both the quality and the quantity of data are inadequate, and that no modelling technique can overcome the fact that at the global level they were all stumbling around in the dark.
