Since early 2020, the onset of the COVID-19 pandemic, physicians have continued to report adverse events associated with care. Patients also continued to participate in the hospital satisfaction surveys. To date, no study in France has measured the impact of the pandemic on adverse events and patient satisfaction.

Are risk factors for preterm and early-term live singleton birth the same? A population-based study in France.

Objectives: To investigate whether risk factors for preterm (<37 weeks gestation) and early-term birth (37 and 38 weeks gestation) are similar.

Design: Nationally representative cross-sectional study of births.

Setting: France in 2010.

Travel Time to Hospital for Childbirth: Comparing Calculated Versus Reported Travel Times in France.

Objectives Timely access to health care is critical in obstetrics. Yet obtaining reliable estimates of travel times to hospital for childbirth poses methodological challenges. We compared two measures of travel time, self-reported and calculated, to assess concordance and to identify determinants of long travel time to hospital for childbirth.

How do late terminations of pregnancy affect comparisons of stillbirth rates in Europe? Analyses of aggregated routine data from the Euro-Peristat Project.

Objective: To describe how terminations of pregnancy at gestational ages at or above the limit for stillbirth registration are recorded in routine statistics and to assess their impact on comparability of stillbirth rates in Europe.

Design: Analysis of aggregated data from the Euro-Peristat project.

Setting: Twenty-nine European countries.

Association Between Planned Cesarean Delivery and Neonatal Mortality and Morbidity in Twin Pregnancies.

Objective: To evaluate the association between the planned mode of delivery and neonatal mortality and morbidity in an unselected population of women with twin pregnancies.

Methods: The JUmeaux MODe d'Accouchement (JUMODA) study was a national prospective population-based cohort study. All women with twin pregnancies and their neonates born at or after 32 weeks of gestation with a cephalic first twin were recruited in 176 maternity units in France from February 2014 to March 2015.

Risk factors of preterm birth in France in 2010 and changes since 1995: Results from the French National Perinatal Surveys.

Objectives: To investigate risk factors of total, spontaneous and induced preterm birth in 2010 and differences between 1995 and 2010.

Material And Methods: The national perinatal surveys are based on a representative sample of births in France. We selected live-born singletons (n=14,326 in 2010 and 12,885 in 1995) and used multiple regression analyses to calculate adjusted odds ratios (aOR) for maternal sociodemographic characteristics, obstetric history, prenatal care and smoking.

Anesthetic and Obstetrical Factors Associated With the Effectiveness of Epidural Analgesia for Labor Pain Relief: An Observational Population-Based Study.

Background And Objectives: The effectiveness of labor epidural analgesia is difficult to explore, as it includes the maternal satisfaction with analgesia as well as the overall childbirth experience. In this population-based study, we sought to identify factors associated with the effectiveness of epidural analgesia for labor pain relief.

Methods: We performed a secondary analysis of the 2010 French National Perinatal Survey, a cross-sectional study of a representative sample of births in France.

[Episiotomy in France in 2010: Variations according to obstetrical context and place of birth].

Objectives: To analyze episiotomy rates according to the characteristics of women and maternity units and to study the variability of rates between units and regions.

Materials And Methods: Our study included all vaginal deliveries in the National Perinatal Survey 2010 (n=11,322). We estimated the adjusted relative risk of episiotomy (aRR) according to women and maternity units characteristics, and we studied the variance between regions and hospitals using multilevel Poisson regressions, stratified on parity.

Variations in rates of severe perineal tears and episiotomies in 20 European countries: a study based on routine national data in Euro-Peristat Project.

Introduction: Rates of severe perineal tears and episiotomies are indicators of obstetrical quality of care, but their use for international comparisons is complicated by difficulties with accurate ascertainment of tears and uncertainties regarding the optimal rate of episiotomies. We compared rates of severe perineal tears and episiotomies in European countries and analysed the association between these two indicators.

Material And Methods: We used aggregate data from national routine statistics available in the Euro-Peristat project.

Socioeconomic inequalities in stillbirth rates in Europe: measuring the gap using routine data from the Euro-Peristat Project.

Background: Previous studies have shown that socioeconomic position is inversely associated with stillbirth risk, but the impact on national rates in Europe is not known. We aimed to assess the magnitude of social inequalities in stillbirth rates in European countries using indicators generated from routine monitoring systems.

Methods: Aggregated data on the number of stillbirths and live births for the year 2010 were collected for three socioeconomic indicators (mothers' educational level, mothers' and fathers' occupational group) from 29 European countries participating in the Euro-Peristat project.

Endometriosis-related infertility: assisted reproductive technology has no adverse impact on pain or quality-of-life scores.

Objective: To evaluate the impact of assisted reproduction technology (ART) on painful symptoms and quality of life (QoL) in women who have endometriosis as compared with disease-free women.

Design: Prospective controlled, observational cohort study.

Setting: University hospital.

[Customized and non-customized French intrauterine growth curves. II - Comparison with existing curves and benefits of customization].

Objectives: Our aim is to compare the new French EPOPé intrauterine growth curves, developed to address the guidelines 2013 of the French College of Obstetricians and Gynecologists, with reference curves currently used in France, and to evaluate the consequences of their adjustment for fetal sex and maternal characteristics.

Population And Methods: Eight intrauterine and birthweight curves, used in France were compared to the EPOPé curves using data from the French Perinatal Survey 2010. The influence of adjustment on the rate of SGA births and the characteristics of these births was analysed.

[Customized and non-customized French intrauterine growth curves. I - Methodology].

Objectives: We developed intrauterine growth references, called EPOPé curves, in line with recommendations for screening of intra-uterine growth restriction issued in 2013 by the French College of Obstetricians and Gynecologists.

Population And Methods: Using the French Perinatal Survey (FPS) 2010, we adapted the methodology developed by Gardosi (1) to model intrauterine growth and its distribution and (2) to adjust for physiological fetal and maternal factors influencing fetal weight. Based on this model, 3 reference curves (unadjusted, adjusted for fetal sex, and adjusted for fetal sex, and maternal height, weight and parity) were proposed.

A global reference for caesarean section rates (C-Model): a multicountry cross-sectional study.

Objective: To generate a global reference for caesarean section (CS) rates at health facilities.

Design: Cross-sectional study.

Setting: Health facilities from 43 countries.

Initial Preference for Labor Without Neuraxial Analgesia and Actual Use: Results from a National Survey in France.

Background: The rate of neuraxial analgesia during labor in France is one of the highest among high-income countries: 77% of vaginal deliveries in 2010. In this context, the question of how women's preferences for delivering without neuraxial analgesia relate to actual use is of interest. Our objective was to study the factors associated with women's initial preference for labor without neuraxial analgesia and those associated with its use in women who initially preferred not to have it.

[Robson classification: A tool for assessment of caesarean practices in France].

Objective: To give a description of caesarean rates in France in 2010 using Robson classification, to assess practices according to the level of care of the maternity units.

Materials And Methods: The study population was the sample of the French National Perinatal Survey in 2010 (n=14,165). Data were stratified by the level of care of the maternity unit (1, 2 or 3).

Prevalence and characteristics of women reporting poor mental health during pregnancy: Findings from the 2010 French National Perinatal Survey.

Background: Self-rated mental health is a useful indicator to examine the positive dimension of mental health and psychological well-being. The primary objective of this study was to estimate the prevalence of poor self-rated mental health during pregnancy in a nationally representative population in France. The second objective was to assess the sociodemographic and medical characteristics associated with this condition and with a health professional's consultation for psychological problems.

Stabilising the caesarean rate: which target population?

Objective: Caesarean rate increased in France between 1995 and 2003, but remained stable between 2003 and 2010. Our objective was to analyse these trends by identifying the groups of women who contributed to the increase and those who contributed to the stabilisation.

Design: Cross-sectional population-based study from the French national perinatal surveys.

Is there a linear relationship between the dose of ruminant trans-fatty acids and cardiovascular risk markers in healthy subjects: results from a systematic review and meta-regression of randomised clinical trials.

The effects of ruminant (R) trans-fatty acids (TFA) on the risk of CVD are still under debate. It could be argued that the lack of the effect of R-TFA may be the result of the small amount of their intake. Taking into consideration the growing available data from intervention studies, we carried out a systematic review and meta-regression to assess the impact of R-TFA intake levels on changes in the total cholesterol: HDL-cholesterol (TC:HDL-C) ratio.

[Medical care and perinatal health in twin pregnancies: situation in 2010 and recent trends in France].

Objective: To compare medical care and health status of twins and singletons in 2010 and to describe the trends between 1995 and 2010 in metropolitan France.

Populations And Methods: Data were derived from the national perinatal surveys from 1995 to 2010, on representative samples of births, and included 14,460 singletons and 440 twins in 2010. We compared prenatal care, childbirth and health status of children between twin and singleton pregnancies and between years.

Cannabis use during pregnancy in France in 2010.

Objective: The aim was to estimate the proportion of women who reported cannabis use during pregnancy, to analyse the demographic and social characteristics of users, and the link between cannabis use and either preterm or small-for-gestational-age birth.

Design: Data were obtained from interviews of a representative sample of women giving birth in France in 2010 in the days after delivery, and from their medical records.

Setting: All maternity units in France.
