Despite increasing attention and investment for maternal, neonatal, and child health, stillbirths remain invisible-not counted in the Millennium Development Goals, nor tracked by the UN, nor in the Global Burden of Disease metrics. At least 2·65 million stillbirths (uncertainty range 2·08 million to 3·79 million) were estimated worldwide in 2008 (≥1000 g(More)
OBJECTIVE To develop and test a new classification system for stillbirths to help improve understanding of the main causes and conditions associated with fetal death. DESIGN Population based cohort study. SETTING West Midlands region. SUBJECTS 2625 stillbirths from 1997 to 2003. MAIN OUTCOME MEASURES Categories of death according to conventional(More)
OBJECTIVE To assess the main risk factors associated with stillbirth in a multiethnic English maternity population. DESIGN Cohort study. SETTING National Health Service region in England. POPULATION 92,218 normally formed singletons including 389 stillbirths from 24 weeks of gestation, delivered during 2009-11. MAIN OUTCOME MEASURE Risk of(More)
BACKGROUND Unexplained antepartum stillbirth is a common cause of perinatal death, and identifying the fetus at risk is a challenge for obstetric practice. Intrauterine growth restriction (IUGR) is associated with a variety of adverse perinatal outcomes, but reports on its impact on unexplained stillbirths by population-based birthweight standards have been(More)
Intrauterine growth restriction (IUGR) remains one of the main challenges in maternity care. Improvements have to start from a better definition of IUGR, applying the concept of the fetal growth potential. Customized standards for fetal growth and birthweight improve the detection of IUGR by better distinction between physiological and pathological(More)
The monitoring of fetal weight is an important aspect of antenatal care. To construct an individually adjustable standard, we developed a model to link the predicted birth weight to a fetal weight curve which outlines how this weight is to be reached in an uncomplicated pregnancy. A formula was derived which describes the median fetal weight at each(More)
OBJECTIVE To analyse the biological factors affecting birthweight and to derive customized birthweight standards for a Spanish population. METHODS A retrospective cohort was created with all the singleton pregnancies delivered at term and free of pathology in our Institution. Birthweight was modeled by multiple linear regression from maternal (ethnic(More)
OBJECTIVE To assess a technique for forward extrapolation of ultrasound-estimated fetal weight to the time of delivery. METHODS A total of 276 women who delivered within 35 days of ultrasound examination were studied. Fetal weight was estimated according to either Hadlock's formula for the biparietal diameter, abdominal circumference and femur length or(More)
OBJECTIVE To examine whether routinely measured variables explained the increased risk of preterm delivery in some UK ethnic groups. DESIGN Cross sectional study of deliveries recorded in the Child Health Record System. SETTING North Birmingham, UK. POPULATION All North Birmingham women delivering singletons, 1994-1997 inclusive. METHOD Logistic(More)
OBJECTIVE To produce standard curves of birth weight according to gestational age validated by ultrasonography in the British population, with particular reference to the effects of ethnic origin. DESIGN Retrospective analysis of computerised obstetric database. SETTING Three large maternity units associated with Nottingham University with over 16,000(More)
