In 2009, nearly 6% of singleton births in the United States occurred at or beyond 42 weeks' gestation.1 More recently, attention has focused on the concept of late-term pregnancy, which is from 41 weeks, 0 days' to 41 weeks, 6 days' gestation.2 Late-term pregnancy is important because of the increasing fetal and maternal risks during this time.The clinical concerns surrounding late-term pregnancy include the risks and anticipated outcomes for expectant management vs.

Although there is no clear evidence that antenatal testing beginning at 41 weeks' gestation prevents intrauterine fetal demise, it is often performed because the risks are low.Term pregnancy is 37 to 41 weeks, with early term being 37 and 38 weeks, full term 39 and 40 weeks, and late term 41 weeks. Babies born before 37 weeks are preterm and are at higher risk of health problems such as cerebral palsy.About 213 million pregnancies occurred in 2012, of which, 190 million were in the developing world and 23 million were in the developed world.The number of pregnancies in women ages 15 to 44 is 133 per 1,000 women.In 2013, complications of pregnancy resulted in 293,000 deaths, down from 377,000 deaths in 1990.

When expectant management is chosen, most experts recommend beginning twice-weekly antenatal surveillance at 41 weeks with biophysical profile or nonstress testing plus amniotic fluid index (modified biophysical profile); induction may be deferred until 42 weeks if this surveillance is reassuring.
