The present study in a case-control study in a population based collection of data of all births from 22 to 32 weeks in all maternities of the Seine-Saint-Denis district for three years, 999 on 67819 total births. The study describes the site of births by level of perinatal care (level 3 maternity associated with a neonatal intensive care unit, level 2 with a neonatal pediatric ward without intensive care, and level 1 without any of these pediatric services. The proportion of births at a level 3 maternity is 6.3% for all births, and 12.9% for live birth of less than 33 weeks. The study describes the transfers of the live babies to a neonatal intensive care by external transfers from level 1 and level 2 units or internal transfers in level 2 and 3 units. All babies are transferred. The study describes the per partum and neonatal deaths up to 28 days by week of gestation duration and site of birth. The study uses the comparison between the deaths during delivery (from 28 to 32 weeks) and in the first 28 days compared to controls, using a regression analysis method. The risk of per partum and neonatal death is: OR = 8.08 [1.03-76.40] when site of birth 2 is compared to 3 and OR = 11.78 [1.33-103.77] when site of birth 1 is compared to 3. The study shows that the french obstetricians and pediatricians have not accepted the international consensus proposing that births of less than 33 weeks should take place in level 3 perinatal units, goal which is reached for 80% of those births, with less neonatal deaths and developmental handicaps.

UI	MeSH Term	Description	Entries
D007226	Infant Mortality	Postnatal deaths from BIRTH to 365 days after birth in a given population. Postneonatal mortality represents deaths between 28 days and 365 days after birth (as defined by National Center for Health Statistics). Neonatal mortality represents deaths from birth to 27 days after birth.

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.

D016015	Logistic Models	Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.

D016022	Case-Control Studies	Comparisons that start with the identification of persons with the disease or outcome of interest and a control (comparison, referent) group without the disease or outcome of interest. The relationship of an attribute is examined by comparing both groups with regard to the frequency or levels of outcome over time.
