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..

Is Grand Multiparity an Independent Risk Factor for Blood Transfusion?

The relation between grand multiparity and poor pregnancy outcome, especially postpartum hemorrhage and blood transfusion, has displayed inconsistent findings. Some studies have identified an increased maternal and neonatal morbidity, but the more recent literature is less clear about the risks. The objective of the study is to determine the association of grand multiparity with postpartum blood transfusion. We conducted a retrospective cohort study in a single tertiary university-affiliated medical center between 2011 and 2019. All women were categorized into one of three groups based on the number of previous deliveries: (a) nulliparous (no previous delivery), (b) multiparous (1-4 previous deliveries), and (c) grand multiparous (≥ 5 previous deliveries). We compared the demographic, clinical, and pregnancy outcomes of the study groups. The primary outcome was the need for red blood cell transfusion during the index admission. During the study period, there were 87,343 deliveries in our center. Among the study population, 36,777 (42.1%) were nulliparous, 49,072 (56.1%) were multipara, and 1494 (1.7%) were grand multiparous. Overall, 1602 women (1.8%) were treated with RBC transfusion. Cesarean delivery, macrosomia, preterm delivery, multiple gestations, antenatal anemia, thrombocytopenia, intrauterine fetal death (IUFD), and prolonged second or third stage of labor were more prevalent among women who were treated with RBC transfusion. After controlling for potential confounders, including maternal age, preterm delivery, IUFD, mode of delivery, and antenatal thrombocytopenia, grand multiparity was found to be an independent protective factor for RBC transfusion (RR = 0.2 (0.007-0.56). After controlling for cofounders, grand multiparity alone is not associated with postpartum blood transfusion.

Trends and Determinants of Small Birth Weight in Ethiopia: Further Analysis of Ethiopian Demographic and Health Surveys

Background

Globally, Low Birth Weight (LBW) prevalence is estimated to be 14.6%. It is a major cause of neonatal mortality in developing countries including Ethiopia. Despite extensive institution-based studies in Ethiopia, there is no comprehensive study using countrywide data. Thus, this study aimed to investigate trends and determinants of Small Birth Weight (SBW) among under-five children in Ethiopia.

Methods

Under-five children data from 2000, 2005, 2011, and 2016 Ethiopian Demographic and Health Surveys (EDHS) were used. However, only 2787 children were weighed at birth and used for analysis in this study. Descriptive statistics and the logistic regression model were used to determine trends and determinants of SBW respectively.

Results

The prevalence of SBW increased from 7.0% (95% CI; 3.1–10.0) to 13.2% (95% CI; 11.4–15.0) between 2000 and 2016. The odds of SBW increased by being a female child (AOR 1.50; 95% CI [1.07–2.09]), mother's with partner occupation of agriculture (AOR 1.54; 95% CI [1.05–2.26]) and mothers who did not know their partner's occupation (AOR 7.35; 95% CI [1.96–27.48]). However, infants born to mothers with primary (AOR 0.43; 95% CI [0.29–0.65]), secondary (AOR 0.30; 95% CI [0.16–0.55]) and higher (AOR 0.55; 95% CI [0.31–0.97]) educational status versus no education and grandmultiparous mothers (OR 0.39; 95% CI [0.19–0.78]) versus primiparous had lower odds of SBW.

Conclusion

In Ethiopia, during the survey period, there was an increment in prevalence of SBW, and maternal related factors were significant determinants. Therefore, empowering mothers through education and improving the socioeconomic status of the household can be one strategy to reduce SBW.

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.

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.

Reasons for current pregnancy amongst grand multiparous Gambian women - a cross sectional survey

Background

While grand multiparity is now relatively rare in the developed world it is still common in Sub Saharan Africa. Although significant resources have been committed to providing modern contraceptive methods in the Gambia, the total fertility rate is still high at 5.6. Determining the reasons grand multiparous women proffer for the current pregnancy may help in understanding this trend and tailoring appropriate messages to address any specific concerns.

Method

A cross sectional survey of grand multiparous women was carried out at the Royal Victoria Teaching Hospital (now Edward Francis Small Teaching Hospital) to determine the reasons for the current pregnancy.

Results

The prevalence of grand multiparity was 26.5 % while the average parity among the study population was 7.2 (sd 1.8). The most common reasons given for the current pregnancy were: the desire for another child (22.8 %), the pregnancy was unplanned - a “mistake” (18.4 %) and the need to replace a dead child (15.4 %).

Conclusion

Grand multiparity is still very common in The Gambia. Additional efforts are required to target those with unplanned pregnancies. Improving child survival may also decrease the prevalence of grand multiparity.

Pre-eclampsia increases the risk of postpartum haemorrhage: a nationwide cohort study in the Netherlands

Background

Postpartum haemorrhage is a leading cause of maternal morbidity and mortality worldwide. Identifying risk indicators for postpartum haemorrhage is crucial to predict this life threatening condition. Another major contributor to maternal morbidity and mortality is pre-eclampsia. Previous studies show conflicting results in the association between pre-eclampsia and postpartum haemorrhage. The primary objective of this study was to investigate the association between pre-eclampsia and postpartum haemorrhage. Our secondary objective was to identify other risk indicators for postpartum haemorrhage in the Netherlands.

Methods

A nationwide cohort was used, containing prospectively collected data of women giving birth after 19 completed weeks of gestation from January 2000 until January 2008 (n =  1 457 576). Data were extracted from the Netherlands Perinatal Registry, covering 96% of all deliveries in the Netherlands. The main outcome measure, postpartum haemorrhage, was defined as blood loss of ≥1000 ml in the 24 hours following delivery. The association between pre-eclampsia and postpartum haemorrhage was investigated with uni- and multivariable logistic regression analyses.

Results

Overall prevalence of postpartum haemorrhage was 4.3% and of pre-eclampsia 2.2%. From the 31 560 women with pre-eclampsia 2 347 (7.4%) developed postpartum haemorrhage, compared to 60 517 (4.2%) from the 1 426 016 women without pre-eclampsia (odds ratio 1.81; 95% CI 1.74 to 1.89). Risk of postpartum haemorrhage in women with pre-eclampsia remained increased after adjusting for confounders (adjusted odds ratio 1.53; 95% CI 1.46 to 1.60).

Conclusion

Women with pre-eclampsia have a 1.53 fold increased risk for postpartum haemorrhage. Clinicians should be aware of this and use this knowledge in the management of pre-eclampsia and the third stage of labour in order to reach the fifth Millenium Developmental Goal of reducing maternal mortality ratios with 75% by 2015.

Obstetric complications in grand and great grand multiparous women

OBJECTIVE

To investigate pregnancy and labour outcomes in grand and great grand multiparous women.

STUDY DESIGN

A retrospective population-based study was conducted between the years 1988 and 2007. Parturients were classified into three groups: multiparous; 2-5 deliveries, grand multiparous; 6-9 deliveries, and great grand multiparous; 10+ deliveries. Stratified analyses included multiple logistic regression models.

RESULTS

A significant linear association was found between parity and adverse maternal and perinatal outcomes such as malpresentation, labour dystocia, caesarean delivery, postpartum haemorrhage, maternal anaemia (HB<10), congenital malformations and perinatal mortality. Using multivariable logistic regression models, grand multiparity was found an independent risk factor for labour dystocia, first stage (OR=1.5, P<0.001), and perinatal mortality (OR=2.0, P<0.001). Great grand multiparity was found an independent risk factor for labour dystocia, first stage (OR=2.6, P<0.001), labour dystocia, second stage (OR=2.1, P<0.001), and perinatal mortality (OR=2.5, P<0.001).

CONCLUSION

Women with high birth order are at increased risk for adverse obstetric outcomes. The risk is higher for great grand multiparous women compared to grand multiparous women. Grand and great grand multiparity are independent risk factors for labour dystocia and perinatal mortality.

Prevalence and risk factors of severe obstetric haemorrhage

OBJECTIVE

To determine the prevalence, causes, risk factors and acute maternal complications of severe obstetric haemorrhage.

DESIGN

Population-based registry study.

POPULATION

All women giving birth (307,415) from 1 January 1999 to 30 April 2004 registered in the Medical Birth Registry of Norway. Information about socio-economic risk factors was obtained from Statistics Norway.

METHODS

Cross-tabulation was used to study prevalence, causes and acute maternal complications of severe obstetric haemorrhage. Associations of severe obstetric haemorrhage with demographic, medical and obstetric risk factors were estimated using multiple logistic regression models.

MAIN OUTCOME MEASURE

Severe obstetric haemorrhage (blood loss of > 1500 ml or blood transfusion).

RESULTS

Severe obstetric haemorrhage was identified in 3501 women (1.1%). Uterine atony, retained placenta and trauma were identified causes in 30, 18 and 13.9% of women, respectively. The demographic factors of a maternal age of > or =30 years and South-East Asian ethnicity were significantly associated with an increased risk of haemorrhage. The risk was lower in women of Middle Eastern ethnicity, more than three and two times higher for emergency caesarean delivery and elective caesarean than for vaginal birth, respectively, and substantially higher for multiple pregnancies, von Willebrand's disease and anaemia (haemoglobin <9 g/dl) during pregnancy. Admissions to an intensive care unit, postpartum sepsis, hysterectomy, acute renal failure and maternal deaths were significantly more common among women with severe haemorrhage.

CONCLUSION

The high prevalence of severe obstetric haemorrhage indicates the need to review labour management procedures. Demographic and medical risk factors can be managed with extra vigilance.

The possible correlation between the patient's immune tolerance level during cesaerean section and the incidence of subsequent emergency peripartum hysterectomy

Introduction. Cesarean section is an independent risk factor for peripartum hysterectomy. As a method of delivery, cesarean section may interfere with a number of molecular changes that occur at the maternal-fetal interface during the course of labor. Methods. The level of CD3, CD56, CD25, and CD69 antigen immunoreactivity was assessed by immunohistochemistry in 26 decidual tissue samples. The tissue samples were obtained from 18 women who underwent cesarean sections at term and from 8 women who underwent cesarean hysterectomies. Results. An increase in the activity and infiltration of immune cells in the decidua sampled during the spontaneous beginning of labor was observed. The further progression of labor was accompanied by a decrease in the number and activity of immune cells. The number of CD56+ and CD3+ cells in the decidua was statistically significantly lower in patients who had undergone cesarean hysterectomies than in those who had had cesarean sections at term. Conclusion. Abnormal immune response during labor may increase the risk for peripartum hysterectomy.

WHO systematic review of maternal mortality and morbidity: the prevalence of uterine rupture

OBJECTIVE

To determine the prevalence of uterine rupture worldwide.

DESIGN

Systematic review of all available data since 1990.

SETTING

Community-based and facility-based reports from urban and rural studies worldwide. Sample Eighty-three reports of uterine rupture rates are included in the systematic review. Most are facility based using cross-sectional study designs.

METHODS

Following a pre-defined protocol an extensive search was conducted of 10 electronic databases as well as other sources. Articles were evaluated according to specified inclusion criteria. Uterine rupture data were collected along with information on the quality of reporting including definitions and identification of cases. Data were entered into a database and tabulated using SAS software.

MAIN OUTCOME MEASURES

Prevalence of uterine rupture by country, period, study design, setting, participants, facility type and data source.

RESULTS

Prevalence figures for uterine rupture were available for 86 groups of women. For unselected pregnant women, the prevalence of uterine rupture reported was considerably lower for community-based (median 0.053, range 0.016-0.30%) than for facility-based studies (0.31, 0.012-2.9%). The prevalence tended to be lower for countries defined by the United Nations as developed than the less or least developed countries. For women with previous caesarean section, the prevalence of uterine rupture reported was in the region of 1%. Only one report gave a prevalence for women without previous caesarean section, from a developed country, and this was extremely low (0.006%).

CONCLUSION

In less and least developed countries, uterine rupture is more prevalent than in developed countries. In developed countries most uterine ruptures follow caesarean section. Future research on the prevalence of uterine rupture should differentiate between uterine rupture with and without previous caesarean section.

Induction of labor in great grandmultipara with misoprostol

OBJECTIVE

To compare the efficacy and complications of intravaginal misoprostol application with oxytocin infusion for induction of labor in great grandmultiparous pregnancies with a Bishop score of <6.

STUDY DESIGN

Sixty-four great grandmultiparous (delivering the tenth, or greater, infant) pregnant patients with a Bishop score of <6 were randomized in two groups with 32 patients receiving 50 microg intravaginal misoprostol four times with 4h intervals, and 32 patients receiving oxytocin infusion for induction of labor starting from 2 mIU/min, increasing it every 30 min with 2 mIU/min increments up to maximum of 40 mIU/min. The time from induction to delivery, the route of delivery, fetal outcome and maternal complications were recorded. Statistical analyses were performed using Mann-Whitney U-test, Chi-Square test and hypothesis test about differences for two proportions (t-test) to determine differences between the two groups. P < or = 0.05 was considered significant.

RESULT

The mean time from induction to delivery was 9.91+/-4.30 and 10.88+/-4.72 h in the misoprostol and oxytocin administered group, respectively, with no significant difference between the groups. The rate of vaginal delivery was 84.4 and 87.5% in the misoprostol and oxytocin administered group, respectively, with no significant difference between the groups (P = 0.72). The rates of placental abruption and postpartum hemorrhage were similar in both groups and no case of uterine rupture occurred. The 1 and 5 min mean Apgar scores were 6.91+/-1.57-8.88+/-1.39 and 7.22+/-1.24-9.06+/-0.84 in the misoprostol and oxytocin administered group with no significant differences between the groups (P = 0.38 and 0.51). No case of asphyxia was present. The rate of admission to neonatal intensive care unit was higher in the misoprostol administered group, but the difference was not significant.

CONCLUSION

Intravaginal misoprostol is an alternative method to oxytocin in induction of labor in great grandmultiparous pregnant women with low Bishop scores, as it is effective, cheap and easy to use. Safety about rare complications and neonatal morbidity needs clarifications with further studies.

High parity and adverse birth outcomes: exploring the maze

BACKGROUND

Despite extensive literature on the topic, it is uncertain if grand (para > or = 5) and great grand (para > or = 10) multiparity are associated with adverse birth outcomes. We critically evaluate the evidence for and against the existence of adverse maternal and/or fetal outcomes in high parity women.

METHODS

An electronic search of MEDLINE and other bibliographic databases (Current Contents, EMBASE, and CAB) was conducted, and all relevant articles in English language were retrieved.

RESULTS

Findings on the association between high parity and maternal-fetal birth outcomes are not consistent. Although the older literature tends to suggest that multiparity is a risk factor for negative birth outcomes, more recent reports are not supportive. Comparison across studies was further complicated by confounding factors like maternal age, socioeconomic status, and levels of prenatal care, as well as by variations in study designs and in the definition of parity itself. Furthermore, most studies that examined women of extreme parity (para > or = 10) were handicapped by inadequate power.

CONCLUSIONS

After accounting for quality, culture, and degrees of associations, the preponderance of evidence seems to point to possible existence of heightened risk for certain medical complications and placental pathologies among women of extreme parity. The literature also provides reasonable evidence for a higher-than-expected likelihood for occurrence of fetal macrosomia with advanced parity.
