Abstract
We examined the trends in stillbirth across gestational age in the United States (US).We conducted a trend analysis using the U.S. Natality and Fetal Death datasets covering 1982 and 2017. We compared the incidence and rates of stillbirth for term, all preterm, moderate-to-late preterm, very preterm, and extreme preterm phenotypes. The incidence of stillbirth decreased for the entire birth cohort over the 36-year period. The rates of overall, term, all preterm, very preterm and moderate-to-late preterm stillbirth decreased from 1982 to 2017; however, the rates for extreme preterm stillbirth increased by about 7.6% over the same study period.
Highlights
Intrauterine death of the fetus at or after 20 weeks of gestation or stillbirth is an important reproductive health indicator, and a significant public health problem.[1]
The Natality data and Fetal Death data files used for the analysis were compiled by the National Center for Health Statistics (NCHS), and made publicly-available by the United States (US) Centers for Disease Control and Prevention (CDC) using National Vital Statistics System (NVSS), which is the oldest system used to register all vital events such as births, deaths, marriages, divorces and fetal deaths.[7]
We calculated the rates of stillbirth, overall, and within each gestational category over 36 years.The percentage of stillbirth was calculated among all births.Temporal trends analysis was performed on the rates of stillbirth over the 36 years of the study period
Summary
Intrauterine death of the fetus at or after 20 weeks of gestation or stillbirth is an important reproductive health indicator, and a significant public health problem.[1]. The aim of this temporal trends analysis was to assess the incidence and rates of stillbirth across various gestational age groups.
