Objective.

The objective of this study is to identify the constitutional, obstetrical, nutritional, pathological and socio-economic factors associated with the birth of newborns small weight at the maternity hospital Sharif Idrissi in the region of Gharb chrarda Bni Hssen.
retrospective study was based on the recording of the data collected from the records established systematically after each delivery over a period of 01/04/2011 to 30/09/2011.
risk factors that were found significantly associated with hypotrophy: the age below 21 years (43% vs 12%), less than the 155 cm size (21% vs 10.5%), antenatal care (18% vs 8%), hypertension (30% vs 10%), malnutrition (30% vs 11%), anemia (27% vs 11%), from the rural (33% vs 11.5 %), birth interval less than 18 months and the birth interval greater than 60 months (13%, 38% vs 5%), the term imprecise (42% vs 9% is attained). Finally the below 21 years age were mostly primiparous women. Against by the higher age than or equal to 35 were multiparous, compared to the reference class (age between 21 and 34 years).
The risk factors identified in this study should be sustained in the prevention of delayed intrauterine growth control. Overall, the improvement of living conditions and proper monitoring of pregnancy coupled with better health and nutrition education is the guarantee of a regression of this situation to the Gharb region.

The objective was to study the episiotomy and perineal tears in the service of Gynecology Obstetrics Health Centre Cherif Idrissi Kenitra the Gharb region.
Analytical study on a sample of 327 women delivered. In this section, we have used standard statistical methods such as: chi-square test, calculating the coefficients of bond and to determine the factors that influence directly or indirectly on the practices of episiotomy, we adopted the analysis of logistic regression.
This study has evaluated the rates and risks associated with the use of episiotomy and perineal tears. Respectively, an episiotomy 41.28% and a rate of perineal tears of 3.6%. In univariate analysis, four risk factors were associated with the occurrence of perineal tears; primiparity (8.1% vs 1.9%), the presentation of posterior release (21.4% vs 2.6%), episiotomy (5.9% vs 1.6%) and macrosomia (9 5 vs 2.5). Against by five factors were found as risk factors associated with the use of episiotomy, primiparity (60.5% vs 2%

Identify parameters from maternal restrictions intrauterine growth and fetal macrosomia. Also from the birth weight and fundal height risk cesarean section. We have highlighted the limitations of growth and fetal macrosomia in mothers from its ranks obesity according to body mass index (BMI) and uterine size and the effect of BMI blood pressure and edema in the uterine height. Small birth weight and macrosomia are then at risk both from either the health of the child or her mother in case of big weight. While clinical identification of these two anomalies early growth should guide the pregnant woman to a specific treatment for the future delivery is not complicated or child, or for his mother.
