Objectives: This was an observational study on cervical length and head perineum distance and the prediction of time of delivery. One-hundred and twenty-five nulliparous women with uncomplicated, term, singleton pregnancy were recruited when they presented to the labor ward with show or infrequent painful uterine contractions (less than three contractions in ten minutes on a 30 min cardiotocogram). Apart from digital vaginal examination to assess cervical length and dilatation, sonographic cervical length and head perineum distance were measured by two-dimensional ultrasound. We compared women who delivered within 72 h of presentation of labor symptoms, with women who did not. After excluding ten women whose labor was induced and delivered within 72 h of presentation, one hundred and fifteen women were included for final data analysis. Main findings: Forty-nine women (42.6%) delivered while sixty-six women (57.4%) remained undelivered at 72 h of presentation of symptoms of labor. There was no statistically significant difference between the two groups on age, presence of show, contractions, fetal head station and presentation and mode of delivery. For the group who had delivered within 72 h of presentation of labor symptoms, the mean sonographic cervical length was 1.87 cm ± 0.62 cm, while the head perineum distance was 6.01 cm ± 1.15 cm. For the other group, the mean sonographic cervical length was 2.10 cm ± 0.83 cm; head perineum distance was 6.03 cm ± 1.18 cm. There was no statistically significant difference between the groups for both sonographic cervical length (p = .90); and head perineum distance (p = .08). We also compared the cervical length measured by digital vaginal examination versus sonography. The median sonographic measurements were 1.47 cm, 2.11 cm and 2.79 cm at “1 cm,” “2 cm” and “3 cm” digital vaginal measurement, respectively. However, there was extensive overlap between digitally and sonographically measured cervical length. Prediction accuracy of cervical length and head perineum distance was poor. The area under curve (AUC) of receiver operating characteristic (ROC) curve were 0.433 for sonographic cervical length and 0.501 for HPD. Conclusion: Transperineal sonographical assessment of cervical length and head perineum distance before labor was not useful in predicting the time of delivery. However, it can be explored as an alternative assessment method when digital vaginal examination is not preferred. [ABSTRACT FROM AUTHOR]

Intimate partner violence is a public health problem with human and economic costs. Although there is a substantial body of literature regarding women's experiences in abusive intimate relationships, information about this kind of violence in the Chinese context is scarce. A review of the research on intimate partner violence in Chinese obstetric/gynecology patients has found 22 published papers representing 15 research studies conducted in Mainland China or Hong Kong. The majority of the studies focus on the prevalence of, and risk factors for, intimate partner violence in this group of women. Among the studies, variations in design, sample, definition of intimate partner violence and range of questions asked were noted. As no standardized instruments were used for the detection of intimate partner violence, a range of prevalence rates (e.g., 3.6-16.8% during pregnancy) and types of violence were reported, and it was difficult to draw meaningful comparisons across the studies. Despite the limitations, much can still be learned from the existing findings, especially in terms of the identification of risk factors in the Chinese context (e.g., in-law conflict and extramarital affairs). Such information could provide a useful basis for further investigation into the cultural context of violent experiences of Chinese women. [ABSTRACT FROM AUTHOR]
