BACKGROUND   Maternal perception of decreased fetal movements has been associated with adverse pregnancy outcomes, including stillbirth. Little is known about other aspects of perceived fetal activity. The objective of this study was to explore the relationship between maternal perception of fetal activity and late stillbirth (≥28 wk gestation) risk. (More)
BACKGROUND In high income countries there has been little improvement in stillbirth rates over the past two decades. Previous studies have indicated an ethnic disparity in the rate of stillbirths. This study aimed to determine whether maternal ethnicity is independently associated with late stillbirth in New Zealand. METHODS Cases were women with a(More)
BACKGROUND In high-income countries, stillbirth rates have been static in recent decades. Unexplained stillbirths account for up to 50% of these deaths. METHODS A case-control study was conducted in Auckland, New Zealand, from July 2006 to June 2009 to explore modifiable risk factors for late stillbirth (≥28 weeks of gestation). Eligible participants were(More)
BACKGROUND Stillbirth affects almost 1% of pregnant women in the Western world but is still not a research priority. AIMS To assess in a cohort of stillbirths: the demographic risk factors, the prevalence of small for gestational age (SGA) by customised and population centiles, and the classification of death using the Perinatal Society of Australia and(More)
OBJECTIVES To determine whether snoring, sleep position, and other sleep practices in pregnant women are associated with risk of late stillbirth. DESIGN Prospective population based case-control study. SETTING Auckland, New Zealand PARTICIPANTS CASES 155 women with a singleton late stillbirth (≥ 28 weeks' gestation) without congenital abnormality(More)
This paper presents a unified representation scheme for the implicit equations of points, lines, and circles. An associated set of geometric algorithms operates successfully on degenerate and nearly degenerate geometry, and when necessary produces degenerate geometric results. Computation errors are interpreted geometrically in order to establish(More)
BACKGROUND Current evidence suggests that fetal movements are an important indicator of fetal well-being. About a quarter of women who present with decreased fetal movements have adverse perinatal outcomes such as intrauterine growth restriction and stillbirth. There are no New Zealand studies reporting maternal knowledge about fetal movements in late(More)
BACKGROUND Deficiencies in investigation and audit of perinatal deaths result in loss of information thereby limiting strategies for future prevention. The Perinatal Society of Australia and New Zealand (PSANZ) developed a clinical practice guideline for perinatal mortality in 2004. AIMS To determine the current use and views of the PSANZ guideline,(More)
INTRODUCTION Stillbirth remains an important public health problem in Australia and New Zealand. The role that antenatal care plays in the prevention of stillbirth in high-income countries is unclear. METHODS Cases were women with a singleton, late stillbirth without congenital abnormality, booked to deliver in the Auckland region and born between July(More)
BACKGROUND The United Kingdom has one of the highest rates of stillbirth in Europe, resulting in approximately 4,000 stillbirths every year. Potentially modifiable risk factors for late stillbirths are maternal age, obesity and smoking, but the population attributable risk associated with these risk factors is small.Recently the Auckland Stillbirth Study(More)
