ABSTRACT

Background: The novel coronavirus disease 2019 (COVID-19) was more devastating in people with comorbidities such as advanced age and immunodeficiency. Another group affected by COVID-19 was pregnant women. Immunological changes during pregnancy and conditions such as gestational diabetes and pre-eclampsia that occur during pregnancy also have effects on the fetus. The aim of this study was to analyze the effects of PCR-proven COVID-19 infection during pregnancy on fetus and newborn. Methods: Between December 2019 and October 2021, data from pregnant women with COVID-19 symptoms or a history of contact with people with COVID-19, infected with PCR-proven COVID-19 virus, were analyzed retrospectively. Clinical and laboratory data of pregnant women were analyzed. Death data associated with COVID-19 were evaluated. Clinical and laboratory findings of newborns related to COVID-19 and mortality data related to COVID-19 were recorded. The study received approval from the Gazi Yasargil Training and Research Hospital ethics committee (09.07.2021/853). Results: We evaluated 327 pregnant women who were followed up in our hospital and whose deliveries ended in live birth, stillbirth, miscarriage, or curettage. One hundred eighty-five (56.6%) of the pregnant women had at least one COVID-19-related symptom. We evaluated the data of 306 live births, 21 intrauterine fetal deaths, and 13 postnatal deaths. Among the postnatal deaths, five infants succumbed directly due to COVID-19 infection. A total of 23 live-born babies (7.5%) were classified as small for gestational age (SGA), while 80 babies (26.1%) were born before 37 weeks of gestation, and 32 babies (10.4%) were born before 32 weeks. Cord blood gas analysis revealed that 19 infants (6.3%) had pH < 7 and base excess (BE) < -12. The rate of perinatal asphyxia was significantly higher in babies born to mothers who did not survive (p = 0.027). A considerable number of infants, 119 (40.3%), were admitted to the neonatal intensive care unit (NICU). Among the seven infants with positive PCR results admitted to the NICU, five (4.2%) did not survive. Conclusion: While COVID-19 infection in pregnancy seriously affects mortality and morbidity in pregnant women, it also causes mortality and morbidity on the fetus.

ABSTRACT

The present study investigated factors associated with the incidence of stillbirth in young hyper-prolific sows within free farrowing systems in tropical environments. A total of 714 live-born and 54 stillborn piglets from 57 Landrace × Yorkshire sows, with an average parity of 2.7 ± 1.0 (range: 1 - 4), were comprehensively investigated. Reproductive variables of the sows, including gestation length, farrowing duration, the total number of piglets born per litter, and the birth order and status of each piglet, were recorded. Differences in the physiological characteristics of live-born and stillborn piglets, such as birth interval, cumulative birth interval, body weight at birth, crown-rump length, body mass index (BMI), ponderal index (PI), meconium staining score, and the percentage of piglets with a broken umbilical cord, were analysed. Piglets were divided into four groups based on the quartiles of birth order (Q1-Q4). On average, the duration of farrowing was 173.3 ± 85.9 min, and the total number of piglets born and number of piglets born alive-per litter were 14.1 ± 3.8 and 12.5 ± 3.5, respectively. The incidence of stillbirth was 6.7% (54/801 piglets). The higher percentages of stillbirths were detected in sows with large litter sizes (≥17 piglets, 10.9%) compared to those with small (≤13 piglets, 6.1%) and moderate (14 - 16 piglets, 2.8%) litter sizes (p < .001). The incidences of stillbirth in Q3 and Q4 of the litters were higher than in Q1 and Q2 (p < .001). Compared to live-born piglets, stillborn piglets had higher cumulative birth interval (103.0 ± 3.71 vs. 142.4 ± 9.35 min, p < .001), BMI (17.1 ± 0.15 vs. 18.4 ± 0.39 kg/m2, p = .002), PI (63.7 ± 0.59 vs. 70.8 ± 1.59 kg/m3, p < .001), meconium staining scores (1.78 ± 0.04 vs. 2.04 ± 0.10, p = .021), and the percentage of piglets born with a ruptured umbilical cord (45.2% vs. 66.0%, p = .004). An increase in the incidence of stillbirth was detected at 60, 120, 150, 180, and ≥ 210 min after the first piglet was born, compared to those born within the first 30 min of farrowing (p < .05). In conclusion, the study found that stillbirths in young, hyper-prolific sows were linked to several factors: large litter sizes (≥17 piglets per litter), prolonged cumulative birth intervals (142.4 min), elevated BMI of 18.4 kg/m2, high PI values of 70.8 kg/m3, increased meconium staining scores, and a higher occurrence of ruptured umbilical cords. To reduce the risk of stillbirth, particularly among piglets with high body indices born later in the birthing process, it is recommended to enhance farrowing supervision for young sows, starting at a cumulative birth interval of 60 min.

ABSTRACT

OBJECTIVES: Violence against women is a widespread public health concern with severe effects to women's sexual and reproductive health, including higher risks for miscarriage or stillbirth, unintended pregnancy and induced abortion. This study examined the association between women exposure to physical violence, psychological violence and sexual and reproductive health outcomes (contraceptive use, miscarriage or stillbirth and abortion) in Germany. METHODS: This study used a cross-sectional research design to analyze data on violence against women and sexual and reproductive health (SRH) outcomes collected through the German Health Interview and Examination Survey for Adults, Wave 1, between 2008 and 2011 (n = 3149 women, aged 18-64 years). Multivariable logistic regression models were used to assess the association between experiences of violence among women and the presence of sexual and reproductive health outcomes, considering the influence of socio-demographic and health-related factors (age, marital status, socioeconomic status, social support, number of children, alcohol consumption, health status, chronic conditions). RESULTS: Three associations remained significant (p<0.05) in fully-adjusted models: (i) exposure to physical violence by a parent or caregiver and birth control pill utilization (aOR, adjusted Odds Ratio, 95% CI: 1.36, 1.02-1.81) (ii) exposure to physical violence since the age of 16 and miscarriage or stillbirth (aOR, 95%CI: 1.89, 1.17-3.04); and (iii) exposure to psychological violence by a parent or caregiver and abortion (aOR, 95%CI: 1.87, 1.30-2.70). CONCLUSIONS: The results suggest that adult German women who experienced physical or psychological violence since the age of 16, including violence perpetrated by a parent or caregiver, were more likely to report miscarriage or stillbirth and abortion. Direct assessment of violence experiences against women should be conducted by healthcare professionals in clinical encounters, particularly by obstetrics and gynaecological specialists, for the prevention of women´s adverse sexual and reproductive health outcomes. Furthermore, violence should be treated as a major public health concern and addressed through a multisectoral approach, involving the healthcare and educational sectors, researchers and relevant policymakers.

ABSTRACT

BACKGROUND: The Safer Baby Bundle (SBB) aimed to reduce stillbirth rates in Australia through improving pregnancy care across five elements; smoking cessation, fetal growth restriction (FGR), decreased fetal movements (DFM), side sleeping in late pregnancy and decision making around timing of birth. We assessed experiences of women and healthcare professionals (HCPs) with antenatal care practices around the five elements. METHODS: A pre-post study design using online surveys was employed to assess change in HCPs awareness, knowledge, and frequency of performing recommended practices (22 in total) and women's experiences of care received related to reducing their chance of stillbirth. Women who had received antenatal care and HCPs (midwives and doctors) at services participating in the SBB implementation program in two Australian states were invited to participate. Surveys were distributed over January to July 2020 (pre) and August to December 2022 (post). Comparison of pre-post responses was undertaken using Fisher's exact, Pearson's chi-squared or Wilcoxon rank-sum tests. RESULTS: 1,225 women (pre-1096/post-129) and 1,415 HCPs (pre-1148/post-267, ≥ 83% midwives) completed the surveys. The frequency of HCPs performing best practice 'all the time' significantly improved post-SBB implementation across all elements including providing advice to women on side sleeping (20.4-79.4%, p < 0.001) and benefits of smoking cessation (54.5-74.5%, p < 0.001), provision of DFM brochure (43.2-85.1%, p < 0.001), risk assessments for FGR (59.2-84.1%, p < 0.001) and stillbirth (44.5-73.2%, p < 0.001). Practices around smoking cessation in general showed less improvement e.g. using the 'Ask, Advise and Help' brief advice model at each visit (15.6-20.3%, p = 0.088). Post-implementation more women recalled conversations about stillbirth and risk reduction (32.2-50.4%, p < 0.001) and most HCPs reported including these conversations in their routine care (35.1-83.0%, p < 0.001). Most HCPs agreed that the SBB had become part of their routine practice (85.0%). CONCLUSIONS: Implementation of the SBB was associated with improvements in practice across all targeted elements of care in stillbirth prevention including conversations with women around stillbirth risk reduction. Further consideration is needed around strategies to increase uptake of practices that were more resistant to change such as smoking cessation support. TRIAL REGISTRATION: The Safer Baby Bundle Study was retrospectively registered on the Australian New Zealand Clinical Trials Registry database, ACTRN12619001777189, date assigned 16/12/2019.

ABSTRACT

INTRODUCTION: Despite the progress in reducing child mortality, the rate remains high, particularly in sub-Saharan African countries. Limited data exist on child survival and other birth outcomes by sex. This study compared survival rates and birth outcomes by sex among neonates and children under 2 in Ethiopia. METHODS: Women who gave birth after 28 weeks of gestation and their newborns were included in the analysis. Survival probabilities were estimated for males and females in the neonatal period as well as the 2-year period following birth using Kaplan-Meier curves. HRs and 95% CIs were compared between males and females under 2. Descriptive statistics and χ2 tests were used to determine the sex-disaggregated variation in the birth outcomes of preterm birth, low birth weight (LBW), stillbirth, small for gestational age (SGA) and large for gestational age (LGA). RESULTS: The study included a total of 3904 women and child pairs. The neonatal mortality rate for males (3.4%, 95% CI 2.6% to 4.2%) was higher compared with females (1.7%, 95% CI 1.1% to 2.3%). The hazard of death during the first 28 days of life was approximately two times higher for males compared with females (HR 1.99, 95% CI 1.30 to 3.06) but was not significantly different after this period. While there was a non-significant difference between males and females in the proportion of preterm, LBW and LGA births, we found a significantly higher proportion of stillbirth (2.7% vs 1.3%, p=0.003) and SGA (20.5% vs 15.6%, p<0.001) for males compared with females. CONCLUSIONS: This study identified a significant sex difference in mortality and birth outcomes. We recommend focusing future research on the mechanisms of these sex differences in order to better design intervention programmes to reduce disparities and improve outcomes for neonates.

ABSTRACT

Background: Pregnancy loss (PL) is a common, yet rarely examined public health issue associated with an increased risk of impaired mental health, particularly depression.Objective: Previous research shows childlessness to be a correlate of depression after PL. First studies also indicate associations of the type of loss, multiple losses, relationship quality, and coping strategies with depression after the loss of a pregnancy. However, results are inconsistent and the few existing studies show methodological deficits. Therefore, we expect higher depression scores for women without living children, and we exploratively examine the associations between the type of loss, the number of losses, relationship quality, and coping strategies with depression scores for women who suffered a PL.Method: In an online setting, N = 172 women with miscarriage (n = 137) or stillbirth (n = 35) throughout the last 12 months completed the Patient Health Questionnaire (PHQ-D), Brief-COPE, and Partnerschaftsfragebogen (PFB), a German questionnaire measuring relationship quality.Results: In a multiple hierarchical regression analysis, stillbirth, ß = 0.15, p = .035, presence of living children, ß = -0.17, p = .022, and self-blame/emotional avoidance, ß = 0.34, p < .001, are predictors of depression scores. However, there was no association between depression symptoms and other coping strategies, relationship quality, and multiple losses.Conclusions: Especially with regard to women who have no living children, have suffered a stillbirth, or are affected by self-blame/emotional avoidance, health care providers should monitor the presence of depressive symptoms. Our results indicate the need for specific instruments measuring coping style and relationship quality after PL, since the standard items of the PFB and the Brief-COPE seem inappropriate for this setting.


Stillbirth is associated with higher maternal depression scores than miscarriage.Women with living children show lower depression scores after pregnancy loss than childless women.Self-blame and emotional avoidance are associated with higher maternal depression scores after pregnancy loss.

ABSTRACT

Placental health and foetal development are dependent upon element homeostasis. Analytical techniques such as mass spectroscopy can provide quantitative data on element concentrations in placental tissue but do not show spatial distribution or co-localisation of elements that may affect placental function. The present study used synchrotron-based X-ray fluorescence microscopy to elucidate element content and distribution in healthy and pathological placental tissue. The X-ray fluorescence microscopy (XFM) beamline at the Australian Synchrotron was used to image trace metal content of 19 placental sections from healthy term (n = 5, 37-39 weeks), foetal growth-restricted (n = 3, <32 weeks, birth weight <3rd centile), postdate (n = 7, >41 completed weeks), and stillbirth-complicated pregnancies (n = 4, 37-40 weeks). Samples were cryo-sectioned and freeze-dried. The concentration and distribution of fourteen elements were detected in all samples: arsenic, bromine, calcium, chlorine, copper, iron, molybdenum, phosphorous, potassium, rubidium, selenium, strontium, sulphur, and zinc. The elements zinc, calcium, phosphorous, and strontium were significantly increased in stillbirth placental tissue in comparison to healthy-term controls. Strontium, zinc, and calcium were found to co-localise in stillbirth tissue samples, and calcium and strontium concentrations were correlated in all placental groups. Molybdenum was significantly decreased in stillbirth, foetal growth-restricted, and postdate placental tissue in comparison to healthy-term samples (p < 0.0001). Synchrotron-based XFM reveals elemental distribution within biological samples such as the placenta, allowing for the co-localisation of metal deposits that may have a pathological role. Our pilot study further indicates low concentrations of placental molybdenum in pregnancies complicated by foetal growth restriction, postdate delivery, and stillbirth.

ABSTRACT

Recent research suggests that fetal exposure to antidepressants (ADs) is significantly associated with fetal death, including stillbirth. However, there has been limited investigation into the timing of AD exposure during pregnancy, the specific effect of each drug, and the possibility of indication bias. To address these gaps in knowledge, we conducted a systematic review of literature and disproportionality analyses using the WHO Safety Database (VigiBaseⓇ). The systematic review provided evidence for increased risks of fetal death with exposure to any selective serotonin reuptake inhibitor (SSRI) at any time of pregnancy, stillbirth with exposure to any AD during the first trimester, and stillbirth with exposure to any SSRI during the first trimester. Disproportionality analyses revealed significant associations with citalopram, clomipramine, paroxetine, sertraline, and venlafaxine. Combining both sets of results, we conclude that exposure to ADs, especially during the first trimester of pregnancy, seems to be associated with fetal mortality, and that ADs with highest placental transfer may be particularly involved. Further research should investigate the links between ADs during early pregnancy and fetal mortality.

ABSTRACT

The critical sociological literature has explored social prescriptions on women's reproductive lives, trajectories, outcomes and aftermaths. However, little attention has been given to how these prescriptions are expressed through temporal negotiations. This article delves into the narratives of Jewish-Israeli women who have experienced stillbirths. In their narratives, these women contest expectations directed towards them in interactions with professionals, family and friends. Within these expectations, a form of dictation over their future comes into being, where a new pregnancy should quickly precede the stillbirth. The focus here lies on how these women navigate and contest these temporal expectations, carving out space for stillbirth as a meaningful and painful event that should be granted attention and for alternative forms of remembering their stillborn and caring for them after their death. They reshape their narratives through what I call "thickening a present tense" and extend care to the stillborn in the aftermath of the stillbirth. This work contributes to scholarly inquiries into reproductive life and probing time as a socially prescribed mechanism for the value and social distribution of care.

ABSTRACT

BACKGROUND: The COVID-19 pandemic had a profound effect on the health sector globally and in South Africa (SA). OBJECTIVE: To review the effects of COVID-19 on maternal, perinatal and reproductive health outcomes and service utilisation in SA. METHODS: Three routine national data collection systems were sourced: the District Health Information System, the Saving Mothers reports of the National Committee on Confidential Enquiry into Maternal Deaths and the Saving Babies reports from the National Perinatal Morbidity and Mortality Committee using data from the Perinatal Problem Identification Program. RESULTS: There were 35% and 8% increases in maternal and stillbirth mortality rates, respectively, in 2020 and 2021, which correlated with the COVID-19 waves. However, in 2022, rates returned to pre-COVID levels. Antenatal visits and facility births showed little change, but there was a shift to more rural provinces. The use of oral and injectable contraceptives and termination of pregnancy services decreased markedly in 2020 and 2021, with a sustained shift to long-acting reversible contraceptives. The increase in maternal deaths was predominantly due to COVID-19 respiratory complications, but also an increase in obstetric haemorrhage. Stillbirths increased significantly (10%) for birthweights between 2 000 g and 2 499 g, categorised mostly as unexplained stillbirths or preterm labour, but no increase in neonatal deaths was observed. Administrative avoidable factors increased by 24% in the 2020 - 2022 triennium, but there was no increase in patient/community level or healthcare provider-related avoidable factors during the pandemic years. CONCLUSION: COVID-19 caused a marked increase in maternal death and stillbirth rates in 2020 and 2021 due to both direct effects of the virus and indirect effects on functioning of the health system. The continued, although modified, health-seeking behaviour of women and the rapid return to pre-COVID-19 mortality rates demonstrates enormous resilience in women and the health system.

ABSTRACT

BACKGROUND: Globally, 2.6 million stillbirths are estimated to occur each year. The causes of stillbirth are often unknown but can be attributed to various causes. Therefore, identifying the determinants of stillbirth is quite important for applying further meaningful interventions. The purpose of this study was to identify the determinants of stillbirth among deliveries conducted at selected public hospitals in the West Shoa Zone, Oromia, Ethiopia. METHODS: A hospital-based unmatched case‒control study with a 1:4 ratio was conducted. A total of 431 (87 cases and 344 controls) participants were involved. A systematic random sampling method was used for control selection. Data were collected using interview administered questionnaire and analysed using SPSS version 26 software. Binary logistic regression analyses were performed for the independent variables and outcome variables. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were estimated to assess the strength of the associations, and statistical significance was declared at P value < 0.05. RESULTS: In this study, 428 mothers who delivered (85 patients and 343 controls) participated, for a 99.3% response rate. Preeclampsia/eclampsia (AOR = 13.43, 95% CI: 5.67-31.82), other health conditions (AOR = 5.39, 95% CI: 2.34-12.46), mal-presentation (AOR = 3.42, 95% CI: 1.50-7.76), umbilical cord accidents (AOR = 2.57, 95% CI: 1.11-5.93), meconium-stained amniotic fluid problems (AOR = 5.01, 95% CI: 2.15-11.67) and low birth weight (AOR = 2.91, 95% CI: 1.28-6.59) were identified as determinant variables of stillbirth. CONCLUSIONS: Low birth weight, referral status, meconium-stained amniotic fluid problems, umbilical cord accidents, mal-presentation and preeclampsia/eclampsia were identified as independent determinants of stillbirth. Therefore, hospitals and health workers are recommended to focus on identifying and preventing these factors.

ABSTRACT

BACKGROUND: Adverse birth outcomes, including preterm birth, low birth weight, and stillbirth, remain a major global health challenge, particularly in developing regions. Understanding the possible risk factors is crucial for designing effective interventions for birth outcomes. Accordingly, this study aimed to develop a predictive model for adverse birth outcomes among childbearing women in Sub-Saharan Africa using advanced machine learning techniques. Additionally, this study aimed to employ a novel data science interpretability techniques to identify the key risk factors and quantify the impact of each feature on the model prediction. METHODS: The study population involved women of childbearing age from 26 Sub-Saharan African countries who had given birth within five years before the data collection, totaling 139,659 participants. Our data source was a recent Demographic Health Survey (DHS). We utilized various data balancing techniques. Ten advanced machine learning algorithms were employed, with the dataset split into 80% training and 20% testing sets. Model evaluation was conducted using various performance metrics, along with hyperparameter optimization. Association rule mining and SHAP analysis were employed to enhance model interpretability. RESULTS: Based on our findings, about 28.59% (95% CI: 28.36, 28.83) of childbearing women in Sub-Saharan Africa experienced adverse birth outcomes. After repeated experimentation and evaluation, the random forest model emerged as the top-performing machine learning algorithm, with an AUC of 0.95 and an accuracy of 88.0%. The key risk factors identified were home deliveries, lack of prenatal iron supplementation, fewer than four antenatal care (ANC) visits, short and long delivery intervals, unwanted pregnancy, primiparous mothers, and geographic location in the West African region. CONCLUSION: The region continues to face persistent adverse birth outcomes, emphasizing the urgent need for increased attention and action. Encouragingly, advanced machine learning methods, particularly the random forest algorithm, have uncovered crucial insights that can guide targeted actions. Specifically, the analysis identifies risky groups, including first-time mothers, women with short or long birth intervals, and those with unwanted pregnancies. To address the needs of these high-risk women, the researchers recommend immediately providing iron supplements, scheduling comprehensive prenatal care, and strongly encouraging facility-based deliveries or skilled birth attendance.

ABSTRACT

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are a significant cause of maternal mortality worldwide. The classification and treatment of hypertension in pregnancy remain debated. We aim to compare the effectiveness of the revised 2017 ACC/AHA blood pressure threshold in predicting adverse pregnancy outcomes. METHODS: We conducted a secondary data analysis of the Alliance for Maternal and Newborn Health Improvement (AMANHI) biorepository study, including 10,001 pregnant women from Bangladesh, Pakistan, and Tanzania. Blood pressure was measured using validated devices at different antenatal care visits. The blood pressure readings were categorized as: normal blood pressure (systolic blood pressure (sBP) < 120 mm Hg and diastolic blood pressure (dBP) < 80 mm Hg), elevated blood pressure (sBP 120-129 and dBP < 80), stage 1 hypertension (sBP 130-139 or dBP 80-89, or both), and stage 2 hypertension (sBP ≥ 140 or dBP ≥ 90, or both). We estimated risk ratios for stillbirths and preterm births, as well as diagnostic test properties of both the pre-existing JNC7 (≥ 140/90) and revised ACC/AHA (≥ 130/80) thresholds using normal blood pressure as reference group. RESULTS: From May 2014 to June 2018, blood pressure readings were available for 9,448 women (2,894 in Bangladesh, 2,303 in Pakistan, and 4,251 in Tanzania). We observed normal blood pressure in 70%, elevated blood pressure in 12.4%, stage 1 hypertension in 15.2%, and stage 2 hypertension in 2.5% of the pregnant women respectively. Out of these, 310 stillbirths and 9,109 live births were recorded, with 887 preterm births. Using the ACC/AHA criteria, the stage 1 hypertension cut-off revealed 15.3% additional hypertension diagnoses as compared to JNC7 criteria. ACC/AHA defined hypertension was significantly associated with stillbirths (RR 1.8, 95% CI 1.4, 2.3). The JNC 7 hypertension cut-off of ≥ 140/90 was significantly associated with a higher risk of preterm births (RR 1.6, 95% CI 1.2, 2.2) and stillbirths (RR 3.6, 95% CI 2.5, 5.3). Both criteria demonstrated low sensitivities (8.4 for JNC-7 and 28.1 for ACC/AHA) and positive predictive values (11.0 for JNC7 and 5.2 for ACC/AHA) in predicting adverse outcomes. CONCLUSION: The ACC/AHA criteria (≥ 130/80) identified additional cases of hypertension but had limited predictive accuracy for stillbirths and preterm births, highlighting the ongoing need for improved criteria in managing pregnancy-related hypertension.

ABSTRACT

BACKGROUND: Our aim was to evaluate the prevalence, mortality, regional and sex distribution of neural tube defects (NTDs) in Finland. METHODS: Data for this population-based study were collected from 1987 to 2018 from the national health and social welfare registers. RESULTS: There were in total 1634 cases of NTDs, of which 511 were live births, 72 pregnancies ended in stillbirth and 1051 were terminations of pregnancy due to fetal anomaly (TOPFA). The total prevalence of NTDs was 8.6 per 10 000 births and it increased slightly annually (OR 1.008; 95% CI: 1.002, 1.013) during the 32-year study period. The birth prevalence of NTDs decreased (OR 0.979; 95% CI: 0.970, 0.987), but the prevalence of TOPFA increased annually (OR 1.024; 95% CI 1.017, 1.031). The perinatal mortality of NTD children was 260.7 per 1000 births and the infant mortality was 184.0 per 1000 live births, whereas these measures in the general population were 4.6 per 1000 births and 3.3 per 1000 live births, respectively. There was no difference in the NTD prevalence between males and females (P-value 0.77). The total prevalence of NTDs varied from 7.1 to 9.4 per 10 000 births in Finland by region. CONCLUSIONS: Although the majority of NTDs are preventable with an adequate folic acid supplementation, the total prevalence increased in Finland during the study period when folic acid supplementation was mainly recommended to high-risk families and to women with folic acid deficiency. NTDs remain an important cause of infant morbidity and mortality in Finland.

ABSTRACT

PROBLEM: The Indonesian Healthcare Program starting in 2014 enabled access to healthcare delivery for large population groups. Guidance of usage, infrastructure and healthcare process development were the most challenging tasks during the implementation period. Due to the high social impact obstetric care and related quality assurance require evidence-based developmental strategies. This study aims for analysis of outcome and maternal health care utilization, as well as differences related to demographic and economic subgroups. METHODS: For univariate group comparison ANOVA method was applied and combined with Scheffé procedure and Bonferoni correction for post-hoc tests. Meanwhile, multivariate approaches through regression analysis based on insurance reimbursement data antenatal, perinatal and postnatal care were performed at the province level. Maternal mortality (MMR) and stillbirth rates were used for outcome. Demographic characteristics, availability of obstetricians (SPOG), midwifes and healthcare infrastructure were included for their determinants. RESULTS: Specialized hospital facilities (type A/B) for advanced care covered a large part of uncomplicated cases (~35%). Differences between insurance membership groups (poor, non-poor) were not seen. Availability of human resources (SPOG, midwifes) (R2 = 0.728; p<0.001) and rural setting (R2 = 0.288; p = 0.001) are correlated with reduced insufficient referral. Their presence within provinces was related to lower occurrence of complicated cases (R2 = 0.294; p = 0.001). However, higher SPOG rates within provinces were also related to high C-section rates (p<0.001). MMR and stillbirth rates can be predicted by availability of human resources and C-section rates explaining 49.0% of variance. CONCLUSIONS: Improvement of perinatal outcome should focus on sufficient referral processes, availability of SPOG in provinces dominated by rural/remote demography and avoidance of overtreatment by high C-section rates. It is very important to regulate the education of obstetricians and gynecologists in Indonesia as well as distribution arrangements regarding to solve the problems with pregnancy complications in remote and rural areas.

ABSTRACT

BACKGROUND: Pregnancy loss and mourning can lead to psychological adverse effects on women's quality of life. This study aimed to evaluate the effect of art therapy on the quality of life of women with pregnancy loss. METHODS: This study was a randomized clinical trial performed on 60 women who recently experienced abortion or stillbirth. After randomization in two groups (30 in each group), women in the intervention group received four session art therapy. In the control group, routine care was performed. The Perinatal Grief Scale and World Health Organization quality of life questionnaire, short version 26, was used to collect data before and eight weeks after intervention, and the result was compared before and after the intervention in both groups. RESULTS: The mean age of participants was 26.5±4.75 years. Eight weeks after the intervention, the mean score of the total quality of life was significantly different between the two groups (348.64±13.12 vs.254.46±58.35; P>0.01). Also, all physical, psychological, social, and environmental dimensions of quality of life improved in the art therapy group compared to the control group (P>0.01). CONCLUSIONS: Art therapy could improve the quality-of-life following pregnancy loss, and can be recommended as a complementary method next to routine care. TRIAL REGISTRATION: IRCT20200104046002N1.

ABSTRACT

BACKGROUND: Adverse pregnancy outcomes, including abortions, miscarriages and stillbirths, are common in developing countries such as Zimbabwe. OBJECTIVE: To determine the trends and factors associated with adverse pregnancy outcomes. METHODS: This article is a secondary data analysis of three repeated cross-sectional Zimbabwe Demographic and Health Surveys to assess adverse pregnancy outcomes among women of reproductive age (15 - 49 years old) who fell pregnant during the study period. Bivariate and multivariable logistic regression models were applied to the 2015 dataset to determine factors associated with adverse pregnancy outcomes. RESULTS: There was an overall increase in reported adverse pregnancy outcomes (stillbirths, miscarriages and abortions) from 2005 to 2015. The percentage of women who experienced adverse pregnancy outcomes among those who fell pregnant in the 5 years preceding each survey rose from 13.4% in 2005 to 13.8% in 2010, followed by a sharp increase to 16.3% in 2015. The multivariable model, belonging to the 35 - 49-year age group, was associated with almost a twofold increased odds of experiencing an adverse pregnancy outcome (adjusted odds ratio (aOR) 2.11, 95% confidence interval (CI) 1.35 - 3.31, p=0.001). Women currently married/in a union (aOR 4.69, 95% CI 2.64 - 8.34, p<0.001) or formerly married/in a union (aOR 3.56, 95% CI 1.89 - 6.69, p=0.001) had higher odds of experiencing an adverse pregnancy outcome. Not belonging to any religion or being a traditionalist or Muslim decreased the odds of experiencing an adverse pregnancy outcome (aOR 0.58, 95% CI 0.42 - 0.80, p=0.001). Women from Harare (aOR 1.56, 95% CI 1.05 - 2.32, p=0.027), Mashonaland West (aOR 1.59, 95% CI 1.08 - 2.36, p=0.027) and Mashonaland Central (aOR 1.76, 95% CI 1.15 - 2.69, p=0.009) provinces had higher odds of experiencing adverse pregnancy outcomes than those from Bulawayo Province. Women who gave birth for the first time at ≥25 years of age (aOR 3.08, 95% CI 2.27 - 4.16, p<0.001) had higher odds of experiencing adverse pregnancy outcomes. Women who delivered 2 - 4 children (aOR 0.75, 95% CI 0.59 - 0.95, p=0.018) or ≥5 children (aOR 0.51, 95% CI 0.36 - 0.72, p<0.001) were less likely to experience adverse pregnancy outcomes. CONCLUSION: Trends showed an increase in the proportion of women experiencing adverse pregnancy outcomes in Zimbabwe from 2005 to 2015. Advanced maternal age, marriage, lack of religion and living in Harare, Mashonaland Central or Mashonaland West were associated with adverse pregnancy outcomes. There is a need to reduce these outcomes through integration of social issues into maternal health programmes, as well as ensuring accessibility and availability of comprehensive reproductive health services that target high-risk groups such as women aged 35 - 49 years.
