Impact of grandmultiparity on obstetric outcome in low resource setting

Trend, prevalence, and associated factors of uterine rupture at Nekemte Specialized Hospital, Oromia Regional State, Western Ethiopia

Maternal morbidity and mortality have long been among the world's most challenging health issues. Uterine rupture is one of the peripartum complications that kills almost one in every thirteen mothers. However, there is limited evidence on uterine rupture trends, proportions, and determinants. Thus, this study assessed the trend, prevalence, and associated factors of uterine rupture at Nekemte Specialized Hospital, Oromia Regional State, Western Ethiopia. An institution-based cross-sectional study was conducted among 2661 clients selected using a systematic random selection technique among the data collected for the project between January 2014 and December 2022 at Nekemte Specialized Hospital. Data were collected through an interview-administered questionnaire and card review from March 2023 to August 2023. The collected data were checked, coded, and entered into Epi info version 7.2 and then exported to SPSS Version 27 for analysis. Logistic regression models were fitted to identify the factors of uterine rupture. Adjusted odds ratio with 95% Confidence Interval was estimated to measure the strength of the association, and statistical significance was declared at a p-value less than 0.05. The trend of uterine rupture declined from 1.54% in 2014 to 0.93% in 2022. The overall prevalence was 3.53% (95%CI: 2.7%, 4.3%). Low household income (Adjusted OR = 3.75, 95%CI: 1.97, 7.13), grandmultiparity (Adjusted OR = 7.78, 95%CI: 4.70, 12.88), having a history of obstetrics complications such as prolonged labor (Adjusted OR = 3.78, 95%CI:2.11, 6.75), a history of cesarean section (Adjusted OR = 2.49, 95%CI:1.42, 4.35), and history of uterine repair (Adjusted OR = 18.01, 95%CI: 6.81, 47.64) were significantly associated with uterine rupture. This finding showed that the trend is declining, and the proportion of uterine rupture is still higher. A more vigilant approach to increase access to lower-income mothers, prevent prolonged and obstructed labor, and maintain antenatal care with complete packages and a referral system are issues to be addressed to minimize the chance of uterine rupture among women.

Perinatal outcomes in grand multiparous women stratified by parity- A large multicenter study

OBJECTIVE

To assess the effect of each additional delivery among grand multiparous (GMP) women on maternal and neonatal outcomes.

METHODS

A multi-center retrospective cohort study that examined maternal and neonatal outcomes of GMP women (parity 5-10, analyzed separately for each parity level) compared to a reference group of multiparous women (parity 2-4). The study population included grand multiparous women with singleton gestation who delivered in one of four university-affiliated obstetrical centers in a single geographic area, between 2003 and 2021. We excluded nulliparous, those with parity > 10 (due to small sample sizes), women with previous cesarean deliveries (CDs), multifetal gestations, and out-of-hospital deliveries. The primary outcome of this study was postpartum hemorrhage (PPH, estimated blood loss exceeding 1000 ml, and/or requiring blood product transfusion, and/or a hemoglobin drop > 3 g/Dl). Secondary outcomes included unplanned cesarean deliveries, preterm delivery, along with other adverse maternal and neonatal outcomes. Univariate analysis was followed by multivariable logistic regression.

RESULTS

During the study period, 251,786 deliveries of 120,793 patients met the inclusion and exclusion criteria. Of those, 173,113 (69%) were of parity 2-4 (reference group), 27,894 (11%) were of parity five, 19,146 (8%) were of parity six, 13,115 (5%) were of parity seven, 8903 (4%) were of parity eight, 5802 (2%) were of parity nine and 3813 (2%) were of parity ten. GMP women exhibited significantly higher rates of PPH starting from parity eight. The adjusted odds ratios (aOR) were 1.19 (95 % CI: 1.06-1.34) for parity 8, 1.17 (95 % CI: 1.01-1.36) for parity 9, and 1.39 (95 % CI: 1.18-1.65) for parity 10. Additionally, they showed elevated rates of several maternal and neonatal outcomes, including placental abruption, large-for-gestational age (LGA) neonates, neonatal hypoglycemia, and neonatal seizures. Conversely, they exhibited decreased risk for other adverse maternal outcomes, including preterm deliveries, unplanned cesarean deliveries (CDs), vacuum-assisted delivery, and third- or fourth-degree perineal tears and small-for-gestational age (SGA) neonates. The associations with neonatal hypoglycemia, and neonatal seizure were correlated with the number of deliveries in a dose-dependent manner, demonstrating that each additional delivery was associated with an additional, significant impact on obstetrical complications.

CONCLUSION

Our study demonstrates that parity 8-10 is associated with a significantly increased risk of PPH. Parity level > 5 correlated with increased odds of placental abruption, LGA neonates, neonatal hypoglycemia, and neonatal seizures. However, GMP women also demonstrated a reduced likelihood of certain adverse maternal outcomes, including unplanned cesarean, preterm deliveries, vacuum-assisted deliveries, SGA neonates, and severe perineal tears. These findings highlight the importance of tailored obstetrical care for GMP women to mitigate the elevated risks associated with higher parity.

Short stature and vaginal dinoprostone as independent predictors of composite maternal-newborn adverse outcomes in induction of labor after one previous cesarean: a retrospective cohort study

BACKGROUND

The rates of labor induction and cesarean delivery is rising worldwide. With the confluence of these trends, the labor induction rate in trials of labor after cesarean can be as high as 27-32.7%. Induction of labor after one previous cesarean (IOLAC) is a high-risk procedure mainly due to the higher risk of uterine rupture. Nevertheless, the American College of Obstetricians and Gynecologists considers IOLAC as an option in motivated and informed women in the appropriate care setting. We sought to identify predictors of a composite of maternal and newborn adverse outcomes following IOLAC.

METHODS

The electronic medical records of women who delivered between January 2018 to September 2022 in a Malaysian university hospital were screened to identify cases of IOLAC. A case is classified as a composite adverse outcome if at least one of these 11 adverse outcomes of delivery blood loss ≥ 1000 ml, uterine scar complications, cord prolapse or presentation, placenta abruption, maternal fever (≥ 38 0C), chorioamnionitis, intensive care unit (ICU) admission, Apgar score < 7 at 5 min, umbilical artery cord artery blood pH < 7.1 or base excess ≤-12 mmol/l, and neonatal ICU admission was present. An unplanned cesarean delivery was not considered an adverse outcome as the practical management alternative for a clinically indicated IOLAC was a planned cesarean. Bivariate analysis of participants' characteristics was performed to identify predictors of their association with composite adverse outcome. Characteristics with crude p < 0.10 on bivariate analysis were incorporated into a multivariable binary logistic regression analysis model.

RESULTS

Electronic medical records of 19,064 women were screened. 819 IOLAC cases and 98 cases with composite adverse outcomes were identified. Maternal height, ethnicity, previous vaginal delivery, indication of previous cesarean, indication for IOLAC, and method of IOLAC had p < 0.10 on bivariate analysis and were incorporated into a multivariable binary logistic regression analysis. After adjustment, only maternal height and IOLAC by vaginal dinoprostone compared to Foley balloon remained significant at p < 0.05. Post hoc adjusted analysis that included all unplanned cesarean as an added qualifier for composite adverse outcome showed higher body mass index, short stature (< 157 cm), not of Chinese ethnicity, no prior vaginal delivery, prior cesarean indicated by labor dystocia, and less favorable Bishop score (< 6) were independent predictors of the expanded composite adverse outcome.

CONCLUSION

Shorter women and IOLAC by vaginal dinoprostone compared to Foley balloon were independently predictive of composite of adverse outcome.

Grand Multiparity and Obstetric Outcomes in a Contemporary Cohort: The Role of Increasing Parity

OBJECTIVE

Evidence is inconsistent regarding grand multiparity and its association with adverse obstetric outcomes. Few large American cohorts of grand multiparas have been studied. We assessed if increasing parity among grand multiparas is associated with increased odds of adverse perinatal outcomes.

STUDY DESIGN

Multicenter retrospective cohort of patients with parity ≥ 5 who delivered a singleton gestation in New York City from 2011 to 2019. Outcomes included postpartum hemorrhage, preterm delivery, hypertensive disorders of pregnancy, shoulder dystocia, birth weight > 4,000 and <2,500 g, and neonatal intensive care unit (NICU) admission. Parity was analyzed continuously, and multivariate analysis determined if increasing parity and other obstetric variables were associated with each adverse outcome.

RESULTS

There were 2,496 patients who met inclusion criteria. Increasing parity among grand multiparas was not associated with any of the prespecified adverse outcomes. Odds of postpartum hemorrhage increased with history (adjusted odds ratio [aOR]: 2.65, 95% confidence interval [1.83, 3.84]) and current cesarean delivery (aOR: 4.59 [3.40, 6.18]). Preterm delivery was associated with history (aOR: 12.36 [8.70-17.58]) and non-White race (aOR: 1.90 [1.27, 2.84]). Odds of shoulder dystocia increased with history (aOR: 5.89 [3.22, 10.79]) and birth weight > 4,000 g (aOR: 9.94 [6.32, 15.65]). Birth weight > 4,000 g was associated with maternal obesity (aOR: 2.92 [2.22, 3.84]). Birth weight < 2,500 g was associated with advanced maternal age (aOR: 1.69 [1.15, 2.48]), chronic hypertension (aOR: 2.45 [1.32, 4.53]), and non-White race (aOR: 2.47 [1.66, 3.68]). Odds of hypertensive disorders of pregnancy increased with advanced maternal age (aOR: 1.79 [1.25, 2.56]), history (aOR: 10.09 [6.77-15.04]), and non-White race (aOR: 2.79 [1.95, 4.00]). NICU admission was associated with advanced maternal age (aOR: 1.47 [1.06, 2.02]) and non-White race (aOR: 2.57 [1.84, 3.58]).

CONCLUSION

Among grand multiparous patients, the risk factor for adverse maternal, obstetric, and neonatal outcomes appears to be occurrence of those adverse events in a prior pregnancy and not increasing parity itself.

KEY POINTS

· Increasing parity is not associated with adverse obstetric outcomes among grand multiparas.. · Prior adverse pregnancy outcome is a risk factor for the outcome among grand multiparas.. · Advanced maternal age is associated with adverse obstetric outcomes among grand multiparas..

Risk of uterine rupture in multiparous women after induction of labor with prostaglandin: A national population-based cohort study

OBJECTIVE

To assess whether, after induction of labor with prostaglandin, multiparous (≥2 para) women have an increased risk of uterine rupture compared with nulliparous or uniparous women.

METHODS

This was a retrospective population-based cohort study including women who underwent induction with prostaglandin in all maternity wards in Sweden between May 1996 and December 2019 (n = 56 784). The study cohort was obtained by using data from the Swedish Medical Birth Register, which contains information from maternity and delivery records. The main outcome measure was uterine rupture.

RESULTS

Overall, multiparous women induced with prostaglandin had an increased risk of uterine rupture compared with nulliparous women (adjusted odds ratio [OR], 3.33 [95% confidence interval (CI), 1.38-8.04]; P < 0.007). Multiparous women with no previous cesarean section (CS) induced with prostaglandin had more than three times higher risk of uterine rupture (crude OR, 3.55 [95% Cl, 1.48-8.53]; P = 0.005) compared with nulliparous women and four times higher risk compared with uniparous women (OR, 4.10 [95% CI, 1.12-15.00]; P < 0.033). Multiparous women with previous CS had a decreased risk of uterine rupture compared with uniparous women with one previous CS (crude OR, 0.41 [95% Cl, 0.21-0.78]; P = 0.007).

CONCLUSION

Our study implies that multiparity in women with no previous CS is a risk factor for uterine rupture when induced with prostaglandin. This should be taken into consideration when deciding on the appropriate method of induction.

Trial of labor after cesarean, vaginal birth after cesarean, and the risk of uterine rupture: an expert review

The decision to pursue a trial of labor after cesarean delivery is complex and depends on patient preference, the likelihood of successful vaginal birth after cesarean delivery, assessment of the risks vs benefits of trial of labor after cesarean delivery, and available resources to support safe trial of labor after cesarean delivery at the planned birthing center. The most feared complication of trial of labor after cesarean delivery is uterine rupture, which can have catastrophic consequences, including substantial maternal and perinatal morbidity and mortality. Although the absolute risk of uterine rupture is low, several clinical, historical, obstetrical, and intrapartum factors have been associated with increased risk. It is therefore critical for clinicians managing patients during trial of labor after cesarean delivery to be aware of these risk factors to appropriately select candidates for trial of labor after cesarean delivery and maximize the safety and benefits while minimizing the risks. Caution is advised when considering labor augmentation and induction in patients with a previous cesarean delivery. With established hospital safety protocols that dictate close maternal and fetal monitoring, avoidance of prostaglandins, and careful titration of oxytocin infusion when induction agents are needed, spontaneous and induced trial of labor after cesarean delivery are safe and should be offered to most patients with 1 previous low transverse, low vertical, or unknown uterine incision after appropriate evaluation, counseling, planning, and shared decision-making. Future research should focus on clarifying true risk factors and identifying the optimal approach to intrapartum and induction management, tools for antenatal prediction, and strategies for prevention of uterine rupture during trial of labor after cesarean delivery. A better understanding will facilitate patient counseling, support efforts to improve trial of labor after cesarean delivery and vaginal birth after cesarean delivery rates, and reduce the morbidity and mortality associated with uterine rupture during trial of labor after cesarean delivery.

Birth asphyxia and its association with grand multiparity and referral among hospital births: A prospective cross-sectional study in Benin, Malawi, Tanzania and Uganda

INTRODUCTION

Birth asphyxia is a leading cause of neonatal mortality in sub-Saharan Africa. The relationship to grand multiparity (GM), a controversial pregnancy risk factor, remains largely unexplored, especially in the context of large multinational studies. We investigated birth asphyxia and its association with GM and referral in Benin, Malawi, Tanzania and Uganda.

MATERIAL AND METHODS

This was a prospective cross-sectional study. Data were collected using a perinatal e-Registry in 16 hospitals (four per country). The study population consisted of 80 663 babies (>1000 g, >28 weeks' gestational age) delivered between July 2021 and December 2022. The primary outcome was birth asphyxia, defined by 5-minute appearance, pulse, grimace, activity and respiration score <7. A multilevel and stratified multivariate logistic regression was performed with GM (parity ≥5) as exposure, and birth asphyxia as outcome. An interaction between referral (none, prepartum, intrapartum) and GM was also evaluated as a secondary outcome. All models were adjusted for confounders.

CLINICAL TRIAL

Pan African Clinical Trial Registry 202006793783148.

RESULTS

Birth asphyxia was present in 7.0% (n = 5612) of babies. More babies with birth asphyxia were born to grand multiparous women (11.9%) than to other parity groups (≤7.6%). Among the 76 850 cases included in the analysis, grand multiparous women had a 1.34 times higher odds of birth asphyxia (95% confidence interval [CI] 1.17-1.54) vs para one to two. Grand multiparous women referred intrapartum had the highest probability of asphyxiation (13.02%, 95% CI 9.34-16.69). GM increased odds of birth asphyxia in Benin (odds ratio [OR] 1.37, 95% CI 1.13-1.68) and Uganda (OR 1.29, 95% CI 1.02-1.64), but was non-significant in Tanzania (OR 1.44, 95% CI 0.81-2.56) and Malawi (OR 0.98, 95% CI 0.67-1.44).

CONCLUSIONS

There is some evidence of an increased risk of birth asphyxia for grand multiparous women having babies at hospitals, especially following intrapartum referral. Antenatal counseling should recognize grand multiparity as higher risk and advise appropriate childbirth facilities. Findings in Malawi suggest an advantage of health systems configuration requiring further exploration.

Inequalities in use of hospitals for childbirth among rural women in sub-Saharan Africa: a comparative analysis of 18 countries using Demographic and Health Survey data

INTRODUCTION

Rising facility births in sub-Saharan Africa (SSA) mask inequalities in higher-level emergency care-typically in hospitals. Limited research has addressed hospital use in women at risk of or with complications, such as high parity, linked to poverty and rurality, for whom hospital care is essential. We aimed to address this gap, by comparatively assessing hospital use in rural SSA by wealth and parity.

METHODS

Countries in SSA with a Demographic and Health Survey since 2015 were included. We assessed rural hospital childbirth stratifying by wealth (wealthier/poorer) and parity (nulliparity/high parity≥5), and their combination. We computed percentages, 95% CIs and percentage-point differences, by stratifier level. To compare hospital use across countries, we produced a composite index, including six utilisation and equality indicators.

RESULTS

This cross-sectional study included 18 countries. In all, a minority of rural women used hospitals for childbirth (2%-29%). There were disparities by wealth and parity, and poorer, high-parity women used hospitals least. The poorer/wealthier difference in utilisation among high-parity women ranged between 1.3% (Mali) and 13.2% (Rwanda). We found use and equality of hospitals in rural settings were greater in Malawi and Liberia, followed by Zimbabwe, the Gambia and Rwanda.

DISCUSSION

Inequalities identified across 18 countries in rural SSA indicate poor, higher-risk women of high parity had lower use of hospitals for childbirth. Specific policy attention is urgently needed for this group where disadvantage accumulates.

Grand multiparity, is it a help or a hindrance in a trial of labor after cesarean section (TOLAC)?

OBJECTIVE

Parity is a prognostic variable when considering trial of labor after cesarean section (TOLAC). This study aimed to determine whether grandmultiparous patients are at increased risk of poor TOLAC outcomes such as uterine rupture.

STUDY DESIGN

A retrospective cohort was conducted at a single university-affiliated medical center with approximately 10,000 deliveries per year. The study group included women post one cesarean section who attempted TOLAC carrying a singleton fetus in vertex presentation. We divided the cohort into three groups: group 1 - women who had a parity of 1; group 2 - parity of 2-4; group 3 - parity of 5 and above. The primary outcome was successful VBAC. Secondary outcomes included mode of delivery, uterine rupture, and combined maternal and neonatal adverse outcomes. Data were analyzed using Fisher's exact test, Chi-square test, ANOVA, and paired t-test.

RESULTS

Five thousand four hundred and forty-seven women comprised the study group: group 1 - 879 patients, group 2 - 2374 patients, and group 3 - 2194 patients. No significant between-group differences were found in gestational age at delivery. Rates of a successful VBAC were 80.6%, 95.4%, and 95.5%, respectively. Group 1 were more likely to have a failed TOLAC compared to group 2 (OR 5.02, 95% CI 3.9-6.5, p<.001) and group 3 (OR 5.17, 95% CI 4.0-6.7, p<.001). There was no increased risk of failed TOLAC when comparing groups 2 and 3 (OR 1.03; 95% CI 0.8-1.4, p=.89). Operative delivery rate differed significantly between all three groups; 25.1%, 6.2%, and 3.6%, for groups 1, 2, and 3, respectively (p<.001). The rate of uterine rupture was significantly higher in group 1 compared to group 2 (1.02% vs. 0.29% p=.02) and group 3 (1.02% vs. 0.2%, p=.01, respectively). There were no differences between group 2 and group 3 (0.29% vs. 0.2% p=.78).

CONCLUSIONS

Grandmultiparity is not associated with an increased risk of uterine rupture during TOLAC.

Do maternal obstetric morbidity and its concomitants differ between sedente and migrant groups? The case of the Oraon populations of Eastern India

The state of pregnancy and child birth is a stretch of intense vulnerability and incurs reproductive cost, which is governed within a specific socio-ecological context. We asked in our research whether the obstetric morbidities at three stages: antepartum, intrapartum and postpartum, and their concomitants differed significantly between sedente and migrant populations. 403 Oraon indigenous women [203 sedente and 200 migrants] living in Eastern India were selected. Data on socio-demographic, reproductive, maternal health care services and obstetric morbidities were collected using semi structured schedules. We applied Categorical Principal Component Analysis (CATPCA) on the first three variables; PC1 and PC4 were loaded with "socio-demographic and maternal health care services" and PC2 and PC3 loaded with "socio-demographic and reproductive" variables. We applied Poisson regression to examine the determinants of obstetric morbidities. Bivariate analyses showed significant (p ≤ 0.05) sedente-migrant differences in variables related to socio-demographic, reproductive, maternal health care and obstetric morbidities. Poisson regression showed migrants were more likely (p ≤ 0.001) to experience ante and intrapartum morbidities than the sedentes, after controlling the confounders. PC1, PC2 and PC3 could significantly (p ≤ 0.05) predict ante and intrapartum morbidities. For postpartum morbidities, barring the variables related to availing of maternal health care services at the time of child delivery and post delivery, neither migration status nor any of the PCs was a significant predictor. For example, participants who delivered their child in health institutions and had episiotomy and/or caesarean delivery (p ≤ 0.01); and those who availed first PNC within the 24 hours of delivery, stayed under medical supervision after delivery for more than 48 hours and received higher coverage of PNCs were more and less likely respectively (p ≤ 0.05) to have experienced postpartum morbidities. We conclude that the maternal obstetric morbidities and their concomitants differed between sedente and migrant Oraon populations owing to their living in differential socio-ecological contexts.

Effect of grand multiparity on adverse maternal outcomes: A prospective cohort study

Background

Grand multiparity remains a risk factor for a wide range of obstetric complications, especially in developing countries. Grand multiparity has been shown to increase the risks of medical and obstetric complications during pregnancies. However, in a research setting, the risk factors associated with adverse maternal outcomes have yet to be adequately investigated among grand multiparity. Furthermore, there is limited information that examines the effect of grand multiparity on pregnancy outcomes in Ethiopia through prospective follow-up design.

Objective

This study aimed to investigate the effect of grand multiparity on pregnancy outcomes in selected public hospitals in the Sidama Region State of Ethiopia.

Methods

A prospective cohort study design was employed on 837 pregnant women who were admitted for delivery in selected public hospitals from January 1 to August 31, 2021. The study subjects were recruited during admission for labor and delivery. Every woman who was admitted to labor wards was screened for eligibility. The exposed group in this cohort was grand multiparity, and the non-exposed group was multiparity. Data collection was started from the first contact after admission and follow-up to discharge for adverse maternal outcomes. The risk factors for adverse maternal outcomes in grand multiparity were investigated using multivariable Poisson regression analysis. The risk factor was reported as an adjusted risk ratio (ARR) with a 95% confidence interval (CI). When the P-value was <0.05, statistical significance was declared.

Results

The cohort's overall cumulative incidence of adverse maternal outcomes were 39.9% (95%CI: 36.6, 43.4%). Among exposed groups, the incidence of adverse maternal outcomes were 47.1% (95%CI: 41.0-53.2) and 36.3% (95% CI: 32.3-40.6) the multiparity. When compared to multiparous women, grand multiparity was associated with a greater risk of postpartum hemorrhage (ARR = 2.1; 95%CI:1.6-2.7) and malpresentation (ARR = 1.3; 95% CI: 1.01-1.7).

Conclusions

Pregnant women with grand multiparity have a higher incidence of adverse maternal outcomes. Grand multiparity increased the risk of adverse maternal outcomes such as postpartum bleeding and malpresentation. In low-resource settings, we recommend that community health education, the provision of accessible and effective contraceptive services, and increased awareness of the adverse maternal outcome among grand multiparity during pregnancy on obstetric performance should be prioritized. Also, trained health providers can effectively decrease the risk factor with good antenatal care and delivery.

Multilevel analysis of grand multiparity: Trend and its determinants in the Sidama National Regional State of Ethiopia: a cross-sectional study design from demographic and health survey 2000-2016

OBJECTIVE

The study was aimed at examining the magnitude, trends and determinants of grand multiparity in the Sidama regional state of Ethiopia.

DESIGN

We retrieved cross-sectional data from the Ethiopia Demographic and Health Survey from 2000 to 2016.

SETTING

Community-based demographic and health survey (DHS) was conducted in Ethiopia.

PARTICIPANTS

The study population was women (aged 15-49 years) who had delivered children with the available DHS data set.

OUTCOMES

Multilevel multivariate logistic regression analyses assessed the relationship between grand multiparity and its determinants.

RESULTS

The magnitude of grand multiparity was 70.8% (95% CI 68.5% to 72.9%). The multilevel multivariable logistic regression model showed illiteracy (adjusted OR (AOR)=2; 95% CI 1.25 to 3.75), non-use of any contraceptive (AOR=3.8; 95% CI 1.2 to 12.2), early marriage (AOR=4.5; 95% CI 2.6 to 7.9), polygamous marriage (AOR=4.2; 95% CI 2.0 to 9.3), short birth intervals (AOR=2.3; 95% CI 1.4 to 3.5) and husband's low education status (AOR=5.8; 95% CI 2.1 to 16.1) were significantly associated with grand multiparity.

CONCLUSIONS

This study revealed that 7 of 10 women were grand multipara, and the magnitude did not show significant change over the last 16 years. Early marriage and early age at first birth, low literacy level, low family planning utilisation, polygamy, short interbirth interval and unmet need for family planning were determinants of grand multiparity. We recommended the stakeholders to design new strategies to address the root cause of high fertility factors in communities.

Delivery risks and outcomes associated with grand multiparity

BACKGROUND

There is limited recent US national data on risk for adverse outcomes associated with grand multiparity.

OBJECTIVE

To examine the association between grand multiparity and severe maternal morbidity (SMM) and other adverse outcomes during delivery hospitalizations in the United States.

METHODS

This repeat cross-sectional study evaluated delivery hospitalizations from 2000 through the third quarter of 2015 to women aged 15-54 in the National (Nationwide) Inpatient Sample database. Temporal trends in deliveries to women with grand multiparity were analyzed using the Cochran-Armitage trend test. The primary outcome studied was SMM, a composite of adverse outcomes defined by the Centers for Disease Control and Prevention. The exposure of interest was grand multiparity diagnosis during delivery hospitalization. Other adverse outcomes analyzed included placental abruption, preterm delivery, postpartum hemorrhage, disseminated intravascular coagulation, shock, hysterectomy, pulmonary edema and acute heart failure, transfusion of blood or blood products, hypertensive diseases of pregnancy, cesarean delivery, eclampsia, and acute renal failure. Log linear regression models were performed to determine the relationship between grand multiparity and adverse outcomes with measures of association demonstrated as unadjusted (RR) and adjusted risk ratios (aRR) with 95%CIs.

RESULTS

From 2000 to 2015, there were an estimated 62,672,862 hospital deliveries with 386,019 deliveries in the setting of grand multiparity. The number of deliveries with a grand multiparity diagnosis increased over the study period from 4.2 per 1000 deliveries in 2000 to 8.6 per 1000 in 2015 (p < .01). Women with grand multiparity were more likely to be older, have comorbidities, be Hispanic or non-Hispanic Black, be from a lower ZIP code income quartile, have Medicaid insurance, and present to an urban teaching hospital for delivery (p < .01 for all). On univariable analysis, grand multiparity was associated with SMM (RR 1.27, 95%CI 1.23-1.32). However, in adjusted analyses accounting for hospital, clinical, and demographic factors, women with grand multiparity were at lower risk of SMM (aRR 0.93, 95%CI 0.89, 0.96). On analysis of individual adverse outcomes, grand multiparity was associated with a higher risk of placental abruption (RR 1.28, 95%CI 1.24-1.31), preterm delivery (RR 1.17, 95%CI 1.16-1.18), postpartum hemorrhage (RR 1.30, 95%CI 1.28-1.32), disseminated intravascular coagulation (RR 1.23, 95%CI 1.16-1.31), shock (RR 2.50, 95%CI 2.20-2.85), hysterectomy (RR 3.20, 95%CI 3.30, 3.41), pulmonary edema and acute heart failure (RR 1.33, 95%CI 1.24-1.42), and transfusion of blood or blood products (RR 1.74, 95%CI 1.70-1.79). Conversely, grand multiparity was associated with a lower risk of hypertensive diseases of pregnancy (RR 0.85, 95%CI 0.84-0.86), cesarean delivery (RR 0.96, 95%CI 0.95-0.96), and eclampsia (RR 0.69, 95%CI 0.60-0.79). There was no significant association between grand multiparity and acute renal failure.

CONCLUSIONS

Delivery hospitalizations with a grand multiparity diagnosis were not associated with increased risk for SMM in adjusted analysis. Grand multiparity was associated with increased risk for hysterectomy and shock although absolute increased risk for these complications was small.

Trial of labor after previous single cesarean delivery in grand-multiparous women: a retrospective cohort study

PURPOSE

To compare pregnancy outcomes in grand-multiparous (GMP) women with and without one previous cesarean delivery (CD), and to evaluate the number of previous successful vaginal deliveries after a CD needed to reduce the complication rate of trials of labor after a previous CD.

METHODS

This is a retrospective cohort study of women with singleton pregnancy at term who had a trial of vaginal delivery between 2007 and 2014 at a tertiary medical center. We compared pregnancy outcomes in GMP women with and without one previous cesarean delivery. The primary outcome was mode of delivery and secondary outcomes were uterine rupture and composite maternal and neonatal morbidity. For the secondary objective, we compared pregnancy outcomes in women in TOLAC, stratified by the number of previous vaginal deliveries.

RESULTS

Overall, 2815 GMP women met the study criteria, of which 310 (11%) had a previous cesarean delivery. The rate of a successful vaginal deliveries (VBAC) was similar, regardless of the presence of a previous cesarean delivery. No other differences in outcomes were found between the groups. In a secondary analysis, it was found that the presence of a single previous VBAC (compared to no previous VBACs) increased the odds of achieving a vaginal delivery in the next trial of labor after cesarean delivery (TOLAC) (aOR 5.66; 95% CI 3.73-8.60), and decreased the risk of maternal or neonatal adverse outcomes (aOR 0.62; 95% CI 0.39-0.97, and aOR 0.49; 95% CI 0.25-0.97, respectively). Multiple prior VBACs (as compared to a single prior VBAC) did not increase the odds of achieving another VBAC.

CONCLUSION

Grand-multiparous women with and without previous uterine scar have comparable pregnancy outcomes. Additionally, after the first VBAC, additional successful VBACs do not improve the success rate in the next TOLAC.

Concerning trends in maternal risk factors in the United States: 1989-2018

BACKGROUND

Increased efforts have focused on reducing maternal morbidity and mortality in the United States (US). Hypertensive disorders of pregnancy, chronic hypertension, diabetes mellitus, very advanced maternal age, and grand multiparity are known contributors to various maternal morbidities, as well as maternal mortality. We aimed to evaluate the trends in these risk factors/complications among US pregnancies during the last three decades (1989-2018).

METHODS

This is a retrospective study based on the CDC natality database. We calculated the annual prevalence of each risk factor/complication from 1989 to 2018. Joinpoint regression analysis was then used to evaluate the trends. Annual percentage changes (APC) were calculated for each of the segments identified by the joinpoint regression, and average annual percentage changes (AAPC) were calculated for the entire period. Relative risks (RR) comparing the prevalence of each risk factor/complication in 2018 to its prevalence in 1989 were also calculated. Subsequent analyses evaluated the trends of the main risk factors/complications by maternal age groups. Statistical significance was determined at p<0·05, and results were presented with 95% confidence intervals.

FINDINGS

Between 1989 and 2018, the prevalence of hypertensive disorders of pregnancy increased by 149% (AAPC 3·2, 95% CI 2·6-3·8), that of chronic hypertension increased by 182% (AAPC 3·7, 95% CI 3·3-4·2), that of diabetes mellitus increased by 261% (AAPC 4·6, 95% CI 4·0-5·2), that of very advanced maternal age increased by 194% (AAPC 3·8, 95% CI 3·6-4·0), and that of grand multiparity increased by 33% (AAPC 1·0, 95% CI 0·8-1·2). Chronic hypertension and diabetes mellitus increased mostly during the past two decades, while hypertensive disorders of pregnancy and grand multiparity increased primarily over the most recent decade. Additionally, women of very advanced maternal age had significantly higher rates of hypertensive disorders of pregnancy, chronic hypertension and diabetes mellitus throughout our study period.

INTERPRETATION

Our study shows a marked increase in the prevalence of five pregnancy risk factors/complications over the past three decades (1989-2018). This may point to a significant deterioration in the health of US pregnant women, which potentially contributes to both maternal morbidity and mortality.

Perinatal Survival and Predictors of Mortality among Mothers with Hypertensive Disorders of Pregnancy at Antenatal care Clinics in Gamo Zone Public Hospitals

BACKGROUND

Pregnancy induced hypertension represents a significant public health problem throughout the world, which may complicate 0.5%-10% of all pregnancies. It is the leading cause of maternal as well perinatal mortality and morbidity worldwide. Pregnancy induced hypertension is a multisystem disorder unique to pregnancy and results in high perinatal mortality. The objective of this study was to determine the survival status, incidence and predictors of perinatal mortality among mothers with pregnancy induced hypertension at antenatal clinics of Gamo Zone public hospitals.

METHODS

Facility-based retrospective cohort study was conducted among selected 576(192 exposed and 384 unexposed) antenatal care attendants' record at Gamo Zone public hospitals from 1st January 2018 to 31st December 2018. Data were entered into Epi data version 3.02 and exported to SPSS V 25 for analysis. Kaplan Meier survival curve together with log rank test was fitted to test the survival time. Statistical significance was declared at P-value ≤0.05 using cox proportional hazard model.

RESULT

The incidence of perinatal mortality was 124/1000 births. The cumulative proportion of surviving at the end of 4th, 8th, 12th and 16th weeks of follow-up among the exposed groups was 96.9%, 93.5%, 82.1% and 61.6% respectively whereas it was 99.5%, 98.9% and 98.5% at the end of 4th, 8th and 12th weeks of follow-up for the non-exposed groups respectively. Parity of ≥5(AHR: 6.3; 95%CI: 1.36,10.55), mothers who delivered at <34 weeks of gestation(AHR:7.8; 95%CI: 2.6,23.1), being preterm(AHR:6; 95%CI: 5.3,19.2), perinatal birth weight ≤2500gm(AHR:6.1; 95&CI: 1.01,37.9), vaginal deliveryn(AHR:2.7; 95%CI:1.13,6.84), maternal highest systolic blood pressure level ≥160mmHg (AHR: 2.3; 95%CI: 1.02,5.55) and prepartum onset of pregnancy induced hypertension (AHR: 6; 95%CI: 5.3,19.2) were statistically significant in multivariable analysis.

CONCLUSION

The risk of perinatal mortality was high among the mothers with pregnancy induced hypertension compared to those of pregnancy induced hypertension free mother,s and the perinatal mortality rate was high. High parity, low gestational age, low number of antenatal care visits, low birth weight, vaginal delivery, antepartum onset of pregnancy induced hypertension and highest maternal systolic blood pressure level were the independent predictors of perinatal mortality.

Trial of labor after cesarean delivery in grand multiparous women: maternal and neonatal outcomes

OBJECTIVE

To evaluate success rates of vaginal birth after cesarean (VBAC) and maternal and neonatal outcomes associated with trial of labor after cesarean in grand multiparous women.

STUDY DESIGN

A retrospective computerized data base study was conducted at a single tertiary center, between 2005 and 2019. The study compared the maternal and neonatal outcomes of trial of labor after cesarean delivery in grand multiparous women (parity ≥ 6) as compared to multiparous women (parity: 3-5). Comparison analysis was performed by univariate analysis and followed by adjusted multiple logistic regression models.

RESULTS

During the study period we identified 2749 and 4294 cases of trial of labor after cesarean in grand multiparous and multiparas, respectively. VBAC was observed in 94.6% of the grand multiparous as compared to 96.5% in the multiparous group, p < .01. The grand multiparous group had a higher rate of postpartum hemorrhage (3 vs. 2.2%, p = .03) and prolonged postpartum hospitalization (1.4 vs. 0.7%, p < .01). The rates of uterine rupture (0.3 vs. 0.2%, p=.50), peripartum hysterectomy (0.1 vs. 0%, p = .33) and adverse neonatal outcomes were comparable between the groups.

CONCLUSION

Trial of labor after cesarean in grand multiparous women is associated with favorable maternal and neonatal outcomes. Consideration and awareness should be given for the increased risk for postpartum hemorrhage, not associated with uterine rupture.

Ovarian hyperstimulation syndrome after assisted reproductive technologies: trends, predictors, and pregnancy outcomes

OBJECTIVES

To assess trends, predictors, and perinatal outcomes of ovarian hyperstimulation syndrome (OHSS) associated with in vitro fertilization (IVF) cycles in the United States.

DESIGN

Retrospective cohort study using National Assisted Reproductive Technology Surveillance System (NASS) data.

SETTING

Not applicable.

PATIENT(S)

Fresh autologous and embryo-banking cycles performed from 2000 to 2015.

INTERVENTIONS(S)

None.

MAIN OUTCOME MEASURE(S)

OHSS, first-trimester loss, second-trimester loss, stillbirth, low birth weight, and preterm delivery.

RESULT(S)

The proportion of IVF cycles complicated by OHSS increased from 10.0 to 14.3 cases per 1,000 from 2000 to 2006, and decreased to 5.3 per 1,000 from 2006 to 2015. The risk of OHSS was highest for cycles with more than 30 oocytes retrieved (adjusted risk ratio [aRR] 3.85). OHSS was associated with a diagnosis of ovulatory disorder (aRR 2.61), tubal factor (aRR 1.14), uterine factor (aRR 1.17) and cycles resulting in pregnancy (aRR 3.12). In singleton pregnancies, OHSS was associated with increased risk of low birth weight (aRR 1.29) and preterm delivery (aRR 1.32). In twin pregnancies, OHSS was associated with an increased risk of second-trimester loss (aRR 1.81), low birth weight (aRR 1.06), and preterm delivery (aRR 1.16).

CONCLUSION(S)

Modifiable predictive factors for OHSS include number of oocytes retrieved, pregnancy following fresh embryo transfer, and the type of medication used for pituitary suppression during controlled ovarian hyperstimulation. Patients affected by OHSS had a higher risk of preterm delivery and low birth weight. Clinicians should take measures to reduce the risk of OHSS whenever possible.

Racial Disparity in Pregnancy Risks and Complications in the US: Temporal Changes during 2007-2018

Maternal race and ethnicity have been associated with differences in pregnancy related morbidity and mortality. We aimed to evaluate the trends of several pregnancy risk factors/complications among different maternal racial/ethnic groups in the US between 2007 and 2018. Specifically, we used the Center for Disease Control and Prevention (CDC) natality files for these years to assess the trends of hypertensive disorders of pregnancy (HDP), chronic hypertension (CH), diabetes mellitus (DM), advanced maternal age (AMA) and grand multiparity (GM) among non-Hispanic Whites, non-Hispanic Blacks and Hispanics. We find that the prevalence of all of these risk factors/complications increased significantly across all racial/ethnic groups from 2007 to 2018. In particular, Hispanic women exhibited the highest increase, followed by non-Hispanic Black women, in the prevalence of HDP, CH, DM and AMA. However, throughout the entire period, the overall prevalence remained highest among non-Hispanic Blacks for HDP, CH and GM, among Hispanics for DM, and among non-Hispanic Whites for AMA. Our results point to significant racial/ethnic differences in the overall prevalence, as well as the temporal changes in the prevalence, of these pregnancy risk factors/complications during the 2007-2018 period. These findings could potentially contribute to our understanding of the observed racial/ethnic differences in maternal morbidity and mortality.

Effect of Grand Multiparity on Pregnancy Outcomes in Women Under 35 Years of Age: a Comparative Study

Introduction:

It is known for many years, that grand multiparity is associated with poor pregnancy outcome with or without considering increasing maternal age.

Aim:

To examine the impact of grand multiparity on pregnancy outcome in young women aged 18–34 years (Young grand multiparas).

Material and Methods:

A prospective comparative cross-sectional study conducted at Omdurman Maternity Hospital, Sudan from January to September 2018. A standard questionnaire was used to gather data on pregnancy outcome in the low-risk group, grand multiparas age < 35 years and grand multiparas age ≥ 35 years. The association between variables was tested with Chi-square test.

Results:

Young grand multiparas have a significant risk of PPH and increased length of hospital stay => 3 days and babies born to young grand multiparas women were more likely of low birth weight and have a higher rate of admission to NICU. Young grand multiparas were similar in their maternal and fetal complication to low-risk pregnancies and significantly less in several complications when compared to older grand multiparas women.

Conclusion:

Young grand multiparas are less likely to develop several pregnancy complications compared to older grand multiparas women. The occurrences of intra-partum complications match that in low-risk pregnancy.

Induction of labor in women with a scarred uterus: does grand multiparity affect the risk of uterine rupture?

BACKGROUND

Previous cesarean delivery is the most important risk factor for subsequent uterine rupture. Data are inconsistent regarding grand multiparity (≥6th delivery) and a risk for uterine rupture. Specifically, no data exist regarding the risk that is associated with labor induction or augmentation in grand multiparous women after cesarean delivery.

OBJECTIVE

This study aimed to examine whether grand multiparity elevates the risk for uterine rupture in trials of labor after 1 previous cesarean that involved induction or augmentation of labor.

STUDY DESIGN

A retrospective multicenter study was conducted that included all trials of labor after cesarean delivery at 24-42 gestational weeks with vertex presentation between the years 2003-2015. The study groups were defined in the following manner: (1) grand multiparous parturients (current delivery ≥6) who underwent labor induction or augmentation; (2) multiparous parturients (delivery 2-5) who underwent induction or augmentation; (3) grand multiparous parturients with no induction or augmentation of labor. The primary outcome was uterine rupture rate, which was defined as complete separation of all uterine layers. Secondary outcomes were obstetric and neonatal complications.

RESULTS

A total of 12,679 labors were included in the study. The study group included 1304 labors of grand multiparous parturients after 1 previous cesarean delivery, of which 800 parturients underwent induction of labor and 504 parturients received labor augmentation. The multiparous group included 3681 parturients with either labor induction or augmentation. The third group included 7694 grand multiparous parturients without induction or augmentation. Incidence of uterine rupture was similar among the 3 study groups (0.3%, 0.3%, and 0.2%, respectively; P=.847). In the multivariable model that was adjusted for maternal age, ethnicity, diabetes mellitus, birthweight, and prolonged second stage of labor, no association was found between grand multiparity and uterine rupture in women with a scarred uterus who underwent labor induction or augmentation.

CONCLUSION

Labor induction/augmentation during trial of labor after cesarean delivery in grand multiparous parturients appears to be a reasonable option that has a similar uterine rupture risk as in multiparous parturients. Avoiding a mandatory cesarean delivery enables reduction of the risk for future multiple cesarean deliveries.

Grandmultiparity, maternal age, and the risk for uterine rupture-A multicenter cohort study

INTRODUCTION

Uterine rupture is a critical complication causing fetal and maternal morbidity and mortality. Data are conflicting regarding whether grandmultiparity (parity ≥ 6) is a risk factor. This multicenter cohort study aimed to determine whether grandmultiparity (parity ≥ 6) poses a risk for uterine rupture in women with no previous cesarean delivery.

MATERIAL AND METHODS

A multicenter retrospective study of deliveries that occurred between the years 2003 and 2015 in three tertiary medical centers. Deliveries of grandmultiparous women were compared with those of multiparous women (parity 2-5). Women with previous cesarean deliveries were excluded. Multivariable regression modeling was applied to control for possible confounders.

RESULTS

A total of 388 784 deliveries of multiparous women with unscarred uteri were recorded during the study period, including 53 965 deliveries of grandmultiparous women and 334 819 deliveries of multiparous women. Grandmultiparous women were significantly older (33.9 ± 5 vs 27.3 ± 5 years; P < 0.0001). Fourteen cases of uterine rupture were recorded in the grandmultiparae group (1 per 3855 labors) vs 41 in the multiparae group (1 per 8166 labors) (odds ratio [OR] 2.07, 95% confidence interval [95% CI] 1.13-3.81; P = 0.030). However, in a multivariable model controlling for maternal age, the association between grandmultiparity and uterine rupture lost its significance (adjusted OR 1.26, 95% CI 0.66-2.41; P = 0.491), and maternal age emerged as an independent predictor of uterine rupture (adjusted OR 1.08, 95% CI 1.04-1.13; P < 0.0001). Additionally, the risk for uterine rupture was elevated in a linear fashion, concomitant with age.

CONCLUSIONS

Maternal age is a risk factor for uterine rupture. Grandmultiparity does not increase the risk beyond that associated with maternal age.

Maternal socio-demographic factors associated with low parity and grand multiparity in Nigeria

Parity may be categorized as low parity (one or two births), multiparity (three or four births), and grand multiparity (five or more births). In Nigeria, studies have examined factors associated with parity among women. However, these studies have focused on the associated factors of grand multiparity with near exclusion of associated factors of low parity. This study addressed this knowledge gap by examining maternal socio-demographic factors associated with both low parity and grand multiparity in Nigeria. The study analyzed secondary data from 2013 Nigeria Demographic and Health Survey (NDHS). The weighted sample size was 25,852 women. With the use of Stata (version 14), analyses were performed at three levels. Multinomial logistic regression was applied at the multivariate level. Results showed that many of the studied maternal characteristics were significantly associated with either low parity or grand multiparity. Results further showed that while late age at first marriage, improved education, never experiencing child mortality, and polygyny increased the likelihood of low parity, improved education, polygyny, never experiencing child mortality, late age at first marriage, and higher household wealth reduced the likelihood of grand multiparity. These factors should be given prominence in population and women-centered programs in the country.

Grand multiparity and the possible risk of adverse maternal and neonatal outcomes: a dilemma to be deciphered

BACKGROUND

The relation between grand multiparity (GMP) and the possible adverse pregnancy outcomes is not well identified. GMP (parity ≥5 births) frequently occurs in the Arab nations; therefore, this study aimed to identify the correlation between GMP and the different adverse maternal and neonatal outcomes in the Saudi population.

METHOD

This cohort study was conducted on a total of 3327 women from the labour ward in King Khaled University Hospital, Riyadh, Saudi Arabia. Primiparous, multiparous and grand multiparous females were included. Socio-demographic data and pregnancy complications like gestational diabetes or hypertension, preeclampsia and intrauterine growth restriction were retrieved from the participants' files. In addition, the labour ward records were used to extract information about delivery events (e.g. spontaneous preterm delivery, caesarean section [CS]) and neonatal outcomes including anthropometric measurements, APGAR score and neonatal admission to the intensive care.

RESULTS

Primiparas responses were more frequent in comparison to multiparas and GMP (56.8% and 33%, and 10.2% respectively). In general, history of miscarriage was elevated (27.2%), and was significantly higher in GMP (58.3%, p < 0.01). Caesarean delivery was also elevated (19.5%) and was significantly high in the GMP subgroup (p < 0.01). However, after adjustment for age, GMP were less likely to deliver by CS (odds ratio: 0.6, 95% CI: 0.4-0.8; p < 0.01). The two most frequent pregnancy-associated complications were gestational diabetes and spontaneous preterm delivery (12.6% and 9.1%, respectively). The former was significantly more frequent in the GMP (p < 0.01). The main neonatal complication was low birth weight (10.7%); nevertheless, neonatal admission to ICU was significantly higher in GMP (p = 0.04), and low birth weight was more common in primiparas (p < 0.01). Furthermore, logistic regression analysis revealed an insignificant increase in the maternal or neonatal risks in GMP compared to multiparas after adjustment for age.

CONCLUSION

Grand multiparous Saudi females have similar risks of maternal and neonatal complications compared to the other parity groups. Advanced age might play a major role on pregnancy outcomes in GMP. Nevertheless, grand multiparty might not be discouraged as long as women are provided with good perinatal care.

Grand multiparity: is it still a risk in pregnancy?

Background

The association of grand multiparity and poor pregnancy outcome has not been consistent for decades. Classifying grand multiparous women as a high-risk group without clear evidence of a consistent association with adverse outcomes can lead to socioeconomic burdens to the mother, family and health systems. We compared the maternal and perinatal complications among grand multiparous and other multiparous women in Dar es Salaam in Tanzania.

Methods

A cross-sectional study was undertaken at Muhimbili National Hospital (MNH). A standard questionnaire enquired the following variables: demographic characteristics, antenatal profile and detected obstetric risk factors as well as maternal and neonatal risk factors. Predictors of adverse outcomes in relation to grand multiparous women were assessed at p = 0.05.

Results

Grand multiparas had twice the likelihood of malpresentation and a threefold higher prevalence of meconium-stained liquor and placenta previa compared with lower-parity women even when adjusted for age. Neonates delivered by grand multiparous women (12.1%) were at three-time greater risk of a low Apgar score compared with lower-parity women (5.4%) (odds ratio (OR), 2.9; 95% confidence interval (CI), 1.5–5.0). Grand multiparity and low birth weight were independently associated with a low Apgar score (OR, 2.4; 95%, CI 1.4–4.2 for GM; OR, 4.2; 95% CI, 2.3–7.8) for low birth weight.

Conclusion

Grand multiparity remains a risk in pregnancy and is associated with an increased prevalence of maternal and neonatal complications (malpresentation, meconium-stained liquor, placenta previa and a low Apgar score) compared with other multiparous women who delivered at Muhimbili National Hospital.
