Determinants of caesarean section in Lebanon: geographical differences.

This study, based on the Lebanese National Perinatal Survey which included 5231 women, examined the relations between the caesarean section (CS) rate and the characteristics of mothers, children, antenatal care and maternity units in two geographical zones of Lebanon (Beirut-Mount Lebanon and the rest of the country) and then looked at geographical variations. This analysis concerned 3846 women with singleton pregnancies and livebirths at low risk of CS, after exclusion of women with a previous CS, non-cephalic fetal presentations, or delivery before 37 weeks' gestation. The principal end point was caesarean delivery.

[Trends in perinatal health in metropolitan France between 1995 and 2003: results from the National Perinatal Surveys].

Objective: To study trends in the main indicators of health, medical practice and risk factors in France. Population and method. A sample of all births during one week was set up in 1995 (N=13,318), 1998 (N=13,718) et 2003 (N=14,737).

Collecting population-based perinatal data efficiently: the example of the Lebanese National Perinatal Survey.

We describe the methodology and the main results of the Lebanese perinatal health survey. The survey was carried out during two consecutive weeks in autumn 1999 and spring 2000, with the aim of obtaining a minimum data set on all births occurring during a short period of time. All live births and stillbirths occurring during these periods in medical settings were recorded.

[Difficulties with the follow-up of a cohort of very preterm infants: The EPIPAGE Paris-Petite-Couronne population].

Objectives: To describe the characteristics of the children of parents who did not respond to a follow-up questionnaire in a cohort of very preterm infants (EPIPAGE study) and to explore the reasons why they did not complete the questionnaires.

Methods: The non-respondents (N = 176) were the parents who did not return the questionnaires at 1 and 2 years. Contacts were organised by telephone calls and at home visits.

Re-hospitalization in infants younger than 29 weeks' gestation in the EPIPAGE cohort.

Aim: To estimate the re-hospitalization rate of extremely preterm children during infancy and associated factors after the recent improvement in survival rates.

Method: The cohort included all children born before 29 wk of gestation in nine French regions in 1997. All admissions between discharge from initial hospitalization and 9 mo after birth were considered.
