BackgroundViolence against pregnant women is an increasing public health concern particularly in low- and middle-income countries. The purpose of this study was to measure the association between intimate partner violence (IPV) during pregnancy and the risk of adverse birth outcomes.MethodsProspective cohort study of 1276 pregnant women in Dong Anh district, Vietnam. Women with gestational age less than 24 weeks were enrolled and interviewed. Repeated interviews were performed at 30–34 weeks gestation to assess experience of IPV during pregnancy and again 48 hours post-delivery to assess the birth outcome including birth weight and gestational age at delivery.ResultsThere was a statistically significant association between exposure to physical violence during pregnancy and preterm birth (PTB) or low birth weight (LBW). After adjustment for age, education, occupation, body mass index (BMI), haemoglobin level, previous adverse pregnancy outcomes, the pregnant women who were exposed to physical violence during pregnancy were five times more likely to have PTB (AOR = 5.5; 95%CI: 2.1–14.1) and were nearly six times more likely to give birth to a child of LBW (AOR = 5.7; 95%CI: 2.2–14.9) as compared to those who were not exposed to physical violence.ConclusionExposure to IPV during pregnancy increases the risk of PTB and LBW. Case-finding for violence in relation to antenatal care may help protect pregnant women and improve pregnancy outcomes.
IntroductionSince the 1980s, sex ratio at birth (male births per 100 female births) has increased in many Asian countries as a result of selective abortions, but to date there has been no such evidence for Viet Nam. Our aim in this paper is to ascertain the situation with respect to sex ratio at birth in Viet Nam over the past five years.Materials and MethodsOriginal data were obtained from sample population surveys in Viet Nam recording annual birth rates since 2000 of about 450,000 women, as well as from two successive birth surveys conducted for the first time in 2007 (1.1 million births). The annual population surveys include specific information on birth history and mothers' characteristics to be used for the analysis of trends and differentials in sex ratio at birth.Results and DiscussionBirth history statistics indicate that the SRB in Viet Nam has recorded a steady growth since 2001. Starting from a level probably close to the biological standard of 105, the SRB reached 108 in 2005 and 112 in 2006, a value significantly above the normal level. An independent confirmation of these results comes from the surveys of births in health facilities which yielded a SRB of 110 in 2006–07. High SRB is linked to various factors such as access to modern health care, number of prenatal visits, level of higher education and employment status, young age, province of residence and prenatal sex determination. These results suggest that prenatal sex determination followed by selective abortion has recently become more common in Viet Nam. This recent trend is a consequence of various factors such as preference for sons, declining fertility, easy access to abortion, economic development as well as the increased availability of ultrasonography facilities.
Background Postnatal depressive symptoms measured by the Edinburgh Postnatal Depression Scale (EPDS) are reported to display measurement variance regarding factor structure and the frequency of specific depressive symptoms. However, postnatal depressive symptoms measured by EPDS have not been compared between women representing three continents. Methods A cross-sectional study including birth cohort samples from Denmark, Vietnam and Tanzania. Women were included during pregnancy at routine care sites. Depressive symptoms were selfreported 40-90 days postpartum using the EPDS. Exploratory and confirmatory factor analyses and generalized additive regression models were performed. Results A total of N=4,516 participated in the study (Denmark N=2,069, Vietnam N=1,278, Tanzania N=1,169). Factor analyses identified three factors (anhedonia, anxiety and depression) that were almost identical in the three study populations. The only variation between countries was that the item 'self-harm' loaded differently. Women from Tanzania and Denmark were more likely to have an EPDS total score above cutoff 12 (12.6% and 6.4%), compared to women from Vietnam (1.9%) (p<0.001). A low level of education was associated with significantly more depressive symptoms after adjusting for country (p<0.001). Limitations EPDS data was collected at a later time point in the Danish sample. Conclusions Postnatal depressive symptoms constitute a three-factor model across cultures including the factors anhedonia, anxiety and depression. The frequency of postnatal depressive symptoms differs between high-, medium-, and low-income countries. However, clinicians should bear in mind that low-educated women worldwide are more likely to experience postnatal depressive symptoms.
BackgroundIntimate partner violence (IPV) is a global problem that affects one-third of all women. The present study aims to develop and determine the validity of a screening instrument for the detection of IPV in pregnant women in Tanzania and Vietnam and to determine the minimum number of questions needed to identify IPV.MethodAn IPV screening instrument based on eight questions was tested on 1,116 Tanzanian and 1,309 Vietnamese women who attended antenatal care before 24 gestational weeks. The women were re-interviewed during their 30th-34th gestational week where the World Health Organization (WHO) IPV questionnaire was used as the gold standard. In all, 255 combinations of eight different questions were first tested on the Tanzanian study population where sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated. In the evaluation of the performance of the question combinations, different IPV types and the frequency of abusive acts were considered. The question combinations that performed best in Tanzania were subsequently evaluated in the Vietnamese study population.ResultsIn Tanzania, a combination of three selected questions including one question on emotional IPV, one on physical IPV and one on sexual IPV was found to be most effective in identifying women who are exposed to at least one type of IPV during pregnancy (sensitivity = .80; specificity = .74). The performance of the identified combination was slightly less effective in Vietnam (sensitivity = .74; specificity = .68). Focusing on different IPV types, the best performance was found for exposure to physical IPV in both Tanzania (sensitivity = .93; specificity = .70) and Vietnam (sensitivity = .96; specificity = .55). In both countries, the sensitivity increased with the frequency of abuse whereas the specificity decreased.ConclusionBy asking pregnant women three simple questions we were able to identify women who were exposed to IPV during pregnancy in two different countries. The question combination performed best in assessing physical IPV where it identified 93% and 96% of Vietnamese and Tanzanian women, respectively, who were exposed to physical IPV.
Background: This study aimed to propose a classification of acetabular defects in advanced-stage hip tuberculosis based on preoperative radiographs and intraoperative evaluation, thereby providing options for reconstructing each type of defect in hip arthroplasty. Materials and Methods: We conducted a prospective study with 45 patients with active hip tuberculosis at stage IV who were treated with a total hip replacement strategy. We collected the patients' acetabular defect data from preoperative radiographs and intraoperative observations. The defects were classified into types based on defect severity and reconstructive complexity. The hip replacement outcomes were evaluated at least 12 months after the operation. Results: The classification system includes three types: type I: localized or extensive defects inside the acetabulum, not affecting the acetabular rim, medial wall, or columns. Type II: extensive defects inside the acetabulum, affecting the acetabular rim or (and) medial wall. Type III: extensive defects inside the acetabulum, causing the medial wall and the acetabular column to lose function. Each type has a corresponding reconstruction. The outcome includes that 41/45 patients had excellent results; 3/45 patients had good results. The patients had good results due to nerve and muscle damage caused by tuberculosis not related to the acetabular defects. Conclusion: This is a simple, practical classification system of acetabular defects in hip tuberculosis. The outcome of hip reconstruction using this classification was excellent without any cases of dislocation or protrusion.
