BACKGROUND Induction of labour (IOL) has become more common among many populations, but the trends and drivers of IOL in the Northern Territory (NT) of Australia are not known. This study investigated trends in IOL and associated factors among NT Aboriginal and non-Aboriginal mothers between 2001 and 2012. METHODS A retrospective analysis of all NT resident women who birthed in the NT between...

Reproductive success is critical for survival of the species. The timely onset of labor and delivery is an important determinant of perinatal outcome. Preterm birth (defined as delivery before 37 weeks’ gestation) and post-term pregnancy (defined as pregnancy continuing beyond 42 weeks) are both associated with a significant increase in perinatal morbidity and mortality. The factors responsible...

OBJECTIVES Labor induction in post-term pregnancy is considered as a conventional process of mothers' care. Shiatsu technique is one of the complementary methods which use for post-term pregnancy induction. Therefore, the researchers decided to examine the effect of Shiatsu technique on the induction of post-term pregnancy. MATERIALS & METHODS This is a randomized control trials which conduct...

In a prospective study of 1000 consecutive primigravidae labour was induced on 95 occasions. None of 16 perinatal deaths and none of 4 cases of suspected brain damage occurred after prolonged pregnancy or pre-eclampsia. It is concluded that a low incidence of induction is compatible with good results and that enthusiasm for the statistical concept of high risk in obstetric practice should be re...

BACKGROUND Expected date of delivery (EDD) is estimated from the last menstrual period (LMP) or ultrasound scan. Conflicts between these estimates especially on the part of the physician and his/her patient could pose a challenge to prevention of prolonged pregnancy. The objective of this study was to determine the perception and acceptability of menstrual dating (EDD derived from LMP) with reg...

OBJECTIVE To examine the effect of parity on the relationship between pre-induction cervical length and the risk of Cesarean section in women undergoing induction of labor for prolonged pregnancy. METHODS In 382 singleton pregnancies, induction of labor was carried out at 41 + 3 to 42 + 1 weeks of gestation. The cervical length was measured by transvaginal sonography before induction. In 71 o...

We examined the association of vitamin D deficiency to risk of cesarean delivery using prospective data in a cohort of 1153 low income and minority gravidae. Circulating maternal 25-hydroxyvitamin D and intact parathyroid hormone were measured at entry to care 13.73 ± 5.6 weeks (mean ± SD). Intake of vitamin D and calcium was assessed at three time points during pregnancy. Using recent Institut...

OBJECTIVE Our main objective was to investigate the association between duration of active labor and severe postpartum hemorrhage. We examined the effect of the total duration of active labor, the effect of each stage of active labor, and the gradient effect of duration of labor on severe postpartum hemorrhage. METHODS A case-control study was generated from a source population of all women a...

BACKGROUND In Japan, the proportion of women aged 35 and older giving birth has greatly increased in recent years, and maternal age is continuing to increase. Advanced maternal age is a risk factor for abnormal delivery, as is hiesho (sensitivity to cold). RESEARCH QUESTION This study aimed to assess whether advanced maternal age and hiesho precipitate premature delivery, premature rupture of...
