The Lancet has launched a series on stillbirths, a neglected global health issue. Around 2.6 million stillbirths (the death of a baby at 28 weeks’ gestation or more) occur each year. Although 98% of these deaths take place in low-income and middle-income countries, stillbirths also continue to affect wealthier nations, with around 1 in every 300 babies stillborn in high-income countries. The Series highlights the rates and causes of stillbirth globally, explores cost-effective interventions to prevent stillbirths (as well as maternal and neonatal deaths), and sets key actions to halve stillbirth rates by 2020. Also included are comments from professional organisations and parent groups, the latter demonstrating the unique tragedy for families of the birth of a baby bearing no signs of life. The series website contains an executive summary, papers, articles, videos, audio files, and links to related articles.
