Project description:Background:Pregnancy outcomes might be affected by unintended pregnancy such as preeclampsia, preterm birth, cesarean section and low birth weight. The aim of the present study is to assess the association between unintended pregnancy and pregnancy outcomes. Methods:This was a cross-sectional study conducted in 103 hospitals in Tehran, Iran, in July 2015. The data were collected by trained midwives. The interested independent variable was unintended pregnancy and also preeclampsia, weight gain during pregnancy, preterm birth, cesarean section and low birth weight were considered as interested outcomes, and the association of unintended pregnancy and interested outcomes were assessed. Results:Out of 5152 cases, 1021 (19.82%) cases were unintended pregnancy. There was no significant relationship between unintended pregnancy and low birth weight (adjusted OR?0.67, 95% CI 0.403-1.13, P?=?0.138), the risk of preterm birth (adjusted OR?1.15, 95% CI 0.850-1.57, P?=?0.351) and preeclampsia (adjusted OR?1.21, 95% CI 0.846-1.75, P?=?0.289). The results of multiple linear regression model showed that the mean difference between two groups was 0.70 kg, and weight gain mean in unintended pregnant women significantly was lower than unintended pregnant women (mean difference?=?0.70, 95% CI 0.14-1.26 kg, P?=?0.014). Multiple logistic regression showed that after adjusting confounders, there was a significant relationship between unintended pregnancy and cesarean section, and the adjusted odds of cesarean section in unintended pregnant women was 1.32 times of intended pregnant women (95% CI 1.07-1.63, P?=?0.009). Conclusion:We found higher risk of cesarean section and inappropriate weight gain during pregnancy as adverse outcomes of unintended pregnancy in adjusted model.

Project description:Maternal obesity in pregnancy, a growing health problem in Australia, adversely affects both mothers and their offspring. Gestational diabetes mellitus (GDM) is similarly associated with adverse pregnancy and neonatal complications. A low-risk digital medical record audit of antenatal and postnatal data of 2132 pregnant mothers who gave birth between 2016-2018 residing in rural-regional Tasmania was undertaken. An expert advisory group guided the research and informed data collection. Fifty five percent of pregnant mothers were overweight or obese, 43.6% gained above the recommended standards for gestational weight gain and 35.8% did not have an oral glucose tolerance test. The audit identified a high prevalence of obesity among pregnant women and low screening rates for gestational diabetes mellitus associated with adverse maternal and neonatal pregnancy outcomes. We conclude that there is a high prevalence of overweight and obesity among pregnant women in rural regional Tasmania. Further GDM screening rates are low, which require addressing.

Project description:ObjectiveSelective serotonin reuptake inhibitor (SSRI) use during pregnancy incurs a low absolute risk for major malformations; however, other adverse outcomes have been reported. Major depression also affects reproductive outcomes. This study examined whether 1) minor physical anomalies, 2) maternal weight gain and infant birth weight, 3) preterm birth, and 4) neonatal adaptation are affected by SSRI or depression exposure.MethodThis prospective observational investigation included maternal assessments at 20, 30, and 36 weeks of gestation. Neonatal outcomes were obtained by blinded review of delivery records and infant examinations. Pregnant women (N=238) were categorized into three mutually exclusive exposure groups: 1) no SSRI, no depression (N=131); 2) SSRI exposure (N=71), either continuous (N=48) or partial (N=23); and 3) major depressive disorder (N=36), either continuous (N=14) or partial (N=22). The mean depressive symptom level of the group with continuous depression and no SSRI exposure was significantly greater than for all other groups, demonstrating the expected treatment effect of SSRIs. Main outcomes were minor physical anomalies, maternal weight gain, infant birth weight, pregnancy duration, and neonatal characteristics.ResultsInfants exposed to either SSRIs or depression continuously across gestation were more likely to be born preterm than infants with partial or no exposure. Neither SSRI nor depression exposure increased risk for minor physical anomalies or reduced maternal weight gain. Mean infant birth weights were equivalent. Other neonatal outcomes were similar, except 5-minute Apgar scores.ConclusionsFor depressed pregnant women, both continuous SSRI exposure and continuous untreated depression were associated with preterm birth rates exceeding 20%.

Project description:ObjectivesTo determine the incidence and risk of adverse obstetric and neonatal outcomes according to SARS-CoV-2 infection severity in pregnant women.MethodOpen prospective study of pregnant women tested for SARS-CoV-2 by serological and molecular assays during pregnancy or delivery in two hospitals in Sao Paulo, Brazil from April 12, 2020, to February 28, 2021. Five groups were considered for analysis: C0, negative COVID-19 results and no COVID-19 symptoms; C1, positive COVID-19 results, and no symptoms; C2, positive COVID-19 results with mild symptoms; C3, positive COVID-19 results with moderate symptoms; and C4, positive COVID-19 results with severe symptoms. The association between obstetric and neonatal outcomes and COVID-19 severity was determined using multivariate analysis.Results734 eligible pregnant women were enrolled as follows: C0 (n = 357), C1 (n = 127), C2 (n = 174), C3 (n = 37), and C4 (n = 39). The following pregnancy and neonatal outcomes were associated with severe COVID-19: oligohydramnios (adjusted Odds Ratio [aOR] = 6.18; 95% CI 1.87‒20.39), fetal distress (aOR = 4.01; 95% Confidence Interval [CI] 1.84‒8.75), preterm birth (aOR = 5.51; 95% CI 1.47‒20.61), longer hospital stay (aOR = 1.66; 95% CI 1.36‒2.02), and admission to the neonatal intensive care unit (aOR = 19.36; 95% CI, 5.86‒63.99). All maternal (n = 6, 15.4%, p < 0.001) and neonatal (n = 5, 12.5%, p < 0.001) deaths and most fetal deaths (n = 4, 9.8%, p < 0.001) occurred in C4 group. Moderate COVID-19 was associated with oligohydramnios (aOR = 6.23; 95% CI 1.93‒20.13) and preterm birth (aOR = 3.60; 95% CI 1.45‒9.27). Mild COVID-19 was associated with oligohydramnios (aOR = 3.77; 95% CI 1.56‒9.07).ConclusionAdverse pregnancy and neonatal outcomes were associated with maternal symptomatic COVID-19 status, and risk increased with disease severity.

Project description:Background Evidence regarding adverse pregnancy outcomes in patients with thyroid cancer has been conflicting, and the effect of thyroid dysfunction caused by thyroid hormone suppression therapy in terms of neonatal thyroid stimulating hormone (TSH) is unclear. This study aimed to investigate whether thyroid cancer was associated with adverse pregnancy outcomes and had an adverse effect on neonatal thyroid function. Methods This was a retrospective study of 212 singleton pregnancies with thyroid cancer and 35,641 controls without thyroid cancer. Data on maternal pregnancy outcomes and neonatal outcomes were analyzed. Results The median TSH level in the thyroid cancer group was significantly lower than that in the control group (0.87 µIU/mL vs. 1.17 µIU/mL; P < 0.001), while the FT4 level was higher than that in the control group (17.16 pmol/L vs. 16.33 pmol/L; P < 0.001). The percentage of thyroid peroxidase antibodies (TPOAb) positive in the thyroid cancer group was significantly higher than that in the control group (25.0% vs. 11.8%; P < 0.001). Pregnancies with thyroid cancer had a higher risk of late miscarriage (OR 7.166, 95% CI: 1.521, 33.775, P = 0.013), after adjusting maternal TPOAb positive, there was no statistical significance (OR 3.480, 95% CI: 0.423, 28.614, P = 0.246). Pregnancies with thyroid cancer had higher gestational weight gain (GWG) (14.0 kg vs. 13.0 kg, P < 0.001). Although there was no significant difference in the prevalence of gestational diabetes mellitus (GDM) (20.8% vs. 17.4%, P = 0.194), the oral glucose tolerance test (OGTT) showed that fasting plasma glucose and 2-hour value in the thyroid cancer group were higher than those in the control group (P = 0.020 and 0.004, respectively). There was no statistically significant difference in TSH between the thyroid cancer group and the control group, regardless of full-term newborns or preterm newborns. Conclusions Thyroid cancer might not have substantial adverse effects on pregnancy outcomes except for excessive GWG. No adverse effect on neonatal TSH was found, but the effect on long-term thyroid function and neuropsychological function in offspring need further study.

Project description:BackgroundGestational weight gain (GWG) and prepregnancy obesity are garnering more attention as determining factors of pregnancy outcomes when it comes to the wellbeing of both the mother and her baby. This study was conducted to describe the pattern of GWG among participants of Riyadh Mother and Baby Multicenter Cohort Study (RAHMA) and to investigate the detrimental effects of excessive GWG and prepregnancy obesity on pregnancy outcomes.MethodsRAHMA is a multicentre cohort study conducted in three hospitals in Riyadh, Saudi Arabia. Participants were categorized according to the Institute of Medicine into inadequate, adequate, and excessive GWG, and stratified by body mass index (BMI) into under/normal weight, overweight, and obese. To examine the independent effect of maternal prepregnancy obesity and GWG, a multivariate regression model was used and adjusted odds ratio (AOR) and 95% Confidence Interval (CI) for each outcome were calculated.ResultsA total of 7029 participants were included in this study; 31.8% had adequate GWG, 25.9% had excessive GWG and 42.3% had inadequate GWG, while 29.7% had normal BMI, 33.3% were overweight, 34.8% were obese, and 2.2% were underweight. Excessive GWG was independently associated with increased risk of hypertensive events, (AOR = 1.77, 95% CI 1.20-2.63). Obesity was associated with higher risk of gestational diabetes (AOR 2.11, 95% CI 1.76-2.53), hypertensive events (AOR 2.06, 95% CI 1.48-3.01), and delivery by emergency caesarean section (AOR = 1.63, 95% CI 1.35-1.97). Infants of obese women had increased odds of macrosomia (AOR 3.11, 95% CI 1.94-4.99) and lower odds of low birth weight (AOR = 0.68, 95% CI 0.53-0.88).ConclusionIn comparison to excessive GWG, which increases the risk of hypertensive events during pregnancy, prepregnancy obesity is associated with more adverse outcomes including GDM, hypertensive events in pregnancy and emergency CS.

Project description:Women with obesity receive intensified antenatal care due to their increased risk of pregnancy complications, even though not all of these women develop complications. We developed a model based on maternal characteristics for prediction of healthy pregnancy outcomes in women with obesity or who are overweight. We assessed whether early-pregnancy metabolites improved prediction. In a population-based cohort study among a subsample of 1180 Dutch pregnant women with obesity or who are overweight, we developed a prediction model using 32 maternal socio-demographic, lifestyle, physical and pregnancy-related characteristics. We determined early-pregnancy amino acids, nonesterifed fatty acids, phospholipids and carnitines in blood serum using liquid chromatography-tandem mass spectrometry. A healthy pregnancy outcome was the absence of fetal death, gestational hypertension, preeclampsia, gestational diabetes, caesarian section, preterm birth, large-for-gestational-age at birth, macrosomia, postpartum weight retention and offspring overweight/obesity at 5 years. Maternal age, relationship status, parity, early-pregnancy body mass index, mid-pregnancy gestational weight gain, systolic blood pressure and estimated fetal weight were selected into the model using backward selection (area under the receiver operating characteristic curve: 0.65 (95% confidence interval 0.61 to 0.68)). Early-pregnancy metabolites did not improve model performance. Thus, in women with obesity or who are overweight, maternal characteristics can moderately predict a healthy pregnancy outcome. Maternal early-pregnancy metabolites have no incremental value in the prediction of a healthy pregnancy outcome.

Project description:Obesity is a well-recognized risk factor for pregnancy complications. Most studies to date are in large cohorts, with results presented in a way that assumes all women living with obesity are at equal risk. This study investigates which women living with obesity are at higher risk of specific pregnancy complications. A systematic search of MEDLINE and Embase identified 7894 prospective or retrospective cohort studies exploring predictors of adverse outcomes among pregnant women living with obesity. Following screening, 61 studies were deemed eligible. Studies were selected if the effects of exposure to any predictor amongst pregnant women living with obesity could be collected. Maternal characteristics assessed for association with adverse outcomes included maternal age, race/ethnicity, maternal height, mode of conception, complement activation factors, and history of various comorbidities/procedures. Gestational diabetes mellitus was the most studied outcome (n = 32), followed by preterm birth (n = 29), preeclampsia (n = 27), low birthweight infants (n = 20), small for gestational age newborns (n = 12), and stillbirth (n = 7). This review identified important characteristics that should be considered during the screening and follow-up sessions of pregnant women living with obesity, including pre-existing type 1 diabetes, maternal age < 20 years or ≥35 years, non-White ethnicity, abdominal adiposity obesity, and history of bariatric surgery.

Project description:We employed accepted, validated symptom-based screening measures to discern attributable risk of obstructive sleep apnea (OSA) to adverse pregnancy outcomes, taking into account potential maternal confounders. Commonly employed OSA screening measures (Berlin and Epworth scales) were performed in the second and third trimesters; maternal and neonatal outcome data were thereafter obtained. The relationship between OSA and outcomes of interest were explored in stratified and multivariate models controlling for potential confounders. The overall prevalence of OSA was 25.4%. Given a nonlinear increase by body mass index (BMI) strata (8.9%, 46%; p < 0.0001), stratified multivariate analysis was subsequently performed. Among nonobese (BMI <30) gravidae, frequency of preeclampsia was significantly higher among women with OSA (adjusted odds ratio = 6.58, 95% confidence interval = 1.04, 38.51; p = 0.035). Among the obese (BMI ≥30) gravidae, infant birth weight ratio (or birth weight by gestational age) was higher with OSA + screening than OSA - (1.099 versus 1.035; p = 0.04), and this association remained significant after adjustment for potential confounders (p = 0.05). OSA prevalence increases significantly among obese gravidae, raising concerns for the overall validity of commonly employed screening measures in pregnancy. Nevertheless, OSA status continues to exert an independent influence, as obese and nonobese gravidae are at increased risk for a limited number of adverse perinatal outcomes in multivariate models.

Project description:We investigated (1) pregnancy and neonatal outcomes in women with and without disabilities, (2) time trends in deliveries, and (3) risks of pregnancy and neonatal complications among women with various disability types and severity. This was a nationwide population-based study merging the database of the Korea National Health Insurance claims, National Health Screening Program for Infants and Children, and Disability Registration System to compare perinatal outcomes in women with and without disabilities. Pregnancy and neonatal outcomes were analyzed during 2007 and 2015, as were time trends of deliveries. Multivariate logistic regression was used to evaluate risk of perinatal outcomes among women with various disability types and severities. Women with disabilities showed higher rates of cesarean section (aOR, 1.73; 95% CI, 1.69-1.77), hypertensive disorders (aOR, 1.74; 95% CI, 1.63-1.86), placenta abruption (aOR, 1.27; 95% CI, 1.12-1.45), placenta previa (aOR, 1.14; 95% CI, 1.05-1.24), stillbirths (aOR, 1.30; 95% CI, 1.17-1.45), preterm births (aOR, 1.67; 95% CI, 1.57-1.78), and LBW (aOR, 1.87; 95% CI, 1.78-1.97) than those without disabilities. From 2007 to 2015, although delivery rate in women with disabilities decreased steeply compared with that in women without disabilities, the rate of cesarean section increased in women with disabilities. Women with intellectual disability and those with vision impairment had the highest number of perinatal complications among women with various types of disabilities. Women with disability had more adverse pregnancy and neonatal outcomes than those without disabilities. Specific disability types & severities are more vulnerable to specific perinatal complications.
