Impact of caesarean section on mode of delivery, pregnancy-induced and pregnancy-associated disorders, and complications in the subsequent pregnancy in Germany.

ABSTRACT: OBJECTIVES:To analyze the impact of caesarean section (CS) on mode of delivery, pregnancy-induced and pregnancy-associated disorders, as well as complications in the subsequent pregnancy within German gynecological practices. METHODS:1,801 women with CS and 1,801 matched women with vaginal delivery (VD) from the IMS Disease Analyzer database were included. The impact of previous CS on the mode of delivery and pregnancy-associated disorders as well as complications prior to or during birth in the subsequent pregnancy were analyzed. Cox regressions were used to determine the influence of CS with regard to these outcomes. RESULTS:Medical abortion and single spontaneous delivery were significantly less frequent in women with a history of CS compared to VD (OR equal to 0.52 and 0.04 respectively), whereas CS after CS was the significantly more common mode of delivery (79.0% versus 9.3%, OR=36.47). Gestational hypertension without significant proteinuria, gestational hypertension with significant proteinuria, and polyhydramnios were more frequent in women with CS than in women with VD (OR equal to 6.80, 1.71, and 2.29). Hemorrhage and maternal care for known or suspected disproportion were more common in the CS group than in the VD group (OR equal to 1.34 and 3.75). Prolonged pregnancy, preterm labor, abnormalities arising from forces of labor, and perineal laceration during delivery were significantly less frequent in women with CS than in women with VD (OR between 0.32 and 0.75), whereas long labor was more common (OR=2.09). CONCLUSION:Women with CS were more likely to undergo further CS and to develop major pregnancy-associated diseases in the following pregnancy compared to women with VD.

Project description:BackgroundCaesarean delivery has increased worldwide, however, the effects on fertility are largely unknown. This systematic review aims to compare subsequent sub-fertility (time to next pregnancy or birth) among women with a Caesarean delivery to women with a vaginal delivery.MethodsSystematic review of the literature including seven databases: CINAHL; the Cochrane Library; Embase; Medline; PubMed; SCOPUS and Web of Knowledge (1945 - October 2012), using detailed search-strategies and reference list cross-checking. Cohort, case-control and cross-sectional studies were included. Two assessors reviewed titles, abstracts, and full articles using standardised data abstraction forms and assessed study quality.Results11 articles were eligible for inclusion in the systematic review, of these five articles which adjusted for confounders were combined in a meta-analysis, totalling 750,407 women using fixed-effect models. Previous Caesarean delivery was associated with an increased risk of sub-fertility [pooled odds ratio (OR) 0.90; 95% CI 0.86, 0.93]. Subgroup analyses by parity [primiparous women: OR 0.91; 95% CI 0.87, 0.96; not limited to primiparous women: OR 0.81; 95% CI 0.73, 0.90]; by publication date (pre-2000: OR 0.80, 95% CI 0.68, 0.94; post-2000: OR 0.90, 95% CI 0.86, 0.94); by length of follow-up (<10 years: OR 0.81, 95% CI 0.73, 0.90; >10 years: OR 0.91, 95% CI 0.87, 0.96); by indication for mode of delivery (specified: 0.92, 95% CI 0.88, 0.97; not specified: OR 0.81, 95% CI 0.73, 0.90); by cohort size (<35,000: OR 0.79, 95% CI 0.67, 0.92; >35,000: OR 0.90, 95% CI 0.87, 0.95), by definition of sub-fertility used divided into (birth interval [BI]: OR 0.89, 95% CI 0.84, 0.94; inter-pregnancy interval [IPI]: OR 0.91, 95% CI 0.85, 0.97; and categorical measures: OR 0.81, 95% CI 0.73, 0.90); continuous measures: OR 0.91, 95% CI 0.87, 0.96) were performed. Results of the six studies not included in the meta-analysis (which did not adjust for confounders) are presented individually.ConclusionsThe meta-analysis shows an increased waiting time to next pregnancy and risk of sub-fertility among women with a previous Caesarean delivery. However, included studies are limited by poor epidemiological methods such as variations in the definition of time to next pregnancy, lack of confounding adjustment, or details of the indication for Caesarean delivery. Further research of a more robust methodological quality to better explore any underlying causes of sub-fertility and maternal intent to delay childbearing is warranted.

Project description:Background:During the last decades, the rate of caesarean section is increasing and this can increase the mortality and morbidity. Up to one third of the caesarean sections are attributed to the elective repeat caesarean section (ERCS). This study aims to evaluate attitudes and factors affecting the choice of pregnant women with one previous caesarean section regarding their mode of delivery in their second pregnancy. By assessing these attitudes, this study can help the efforts in developing strategies to increase the rates of vaginal delivery. Material and methods:A cross-sectional design was conducted by a structured questionnaire on 166 pregnant women who had delivered once by caesarean section for their first pregnancy and were in the third trimester of their second pregnancy. Any women with an absolute indication for caesarean section was excluded. The study comprises women who attend the clinic at our center in Northern of Jordan. Proper statistical tests were performed to assess the association between the choice of delivery and selected demographic and clinical factors. Results:About 55.4% responded that they would choose ERCS (n = 92) and the remaining participants chose trial of labour after caesarean section (TOLAC) (n = 74). Fear of pain was the most common reason for choosing caesarean section, accounting for 55.4%. Interestingly, our study did not show a significant association between the mode of delivery and demographic factors, such as age, educational level and occupation. The single independent significant factor influencing patients' choice that our study revealed was "being informed about the complications of TOLAC". The choice of TOLAC was almost four times higher for those participants who had been informed about the complications, compared to those who had not been informed. Conclusion:Proper counselling is a main factor that affected the patients' choice toward the mode of delivery. Proper pain management may encourage patients to choose TOLAC because fear of pain was a main reason that patients requested ERCS instead of TOLAC.

Project description:OBJECTIVE:To estimate whether weight gain between deliveries is associated with an increased risk of hypertensive disorders in a subsequent pregnancy. METHODS:This is a case-control study of women who had two live singleton births of at least 24 weeks of gestation at a single maternity hospital from January 1, 2005, to December 31, 2015, with no hypertensive disorder documented in the index pregnancy. Maternal weight gain between deliveries was measured as the change in body mass index (BMI) at delivery. Women who were diagnosed with any hypertensive disorder in the subsequent pregnancy were compared with those who experienced no hypertensive disorder in the subsequent pregnancy using ? statistics for categorical variables and t tests for continuous variables. Logistic regression was used to determine whether weight gain remained independently associated with hypertensive disorders after adjusting for potential confounders. RESULTS:Of 1,033 women, 188 (18.2%) were diagnosed with a hypertensive disorder in the subsequent pregnancy. Of these, 166 (88.3%) had a hypertensive disorder specific to pregnancy (gestational hypertension; preeclampsia; superimposed preeclampsia; or hemolysis, elevated liver enzymes, and low platelet count syndrome), and 22 (11.7%) had chronic hypertension only. Greater weight gain between deliveries was significantly associated with a higher frequency of hypertensive disorders, which remained significant for a BMI increase of at least 2 kg/m in multivariable analyses (adjusted odds ratio [OR] 1.76, 95% CI 1.14-2.74 for 2 to less than 4 kg/m, adjusted OR 3.19, 95% CI 1.86-5.47 for 4 kg/m or more). Conversely, weight loss of 2 kg/m or more was associated with a decreased risk of a hypertensive disorder (adjusted OR 0.41, 95% CI 0.21-0.81). CONCLUSION:Among women with no hypertensive disorder noted in an index pregnancy, an increase in BMI of at least 2 kg/m between deliveries was independently associated with an increased risk of a hypertensive disorder in a subsequent pregnancy.
