[Observational study of a social device for women in precarious situations during pregnancy and post-partum]. / Étude observationnelle d'un dispositif d'aide aux femmes en situation de précarité pendant la grossesse et le post-partum.

OBJECTIVES: To assess the impact of the Regional experimental accompanying nutrition and breast-feeding for pregnant women (PRENAP) 75 social device on the duration of postpartum hospitalization and breast-feeding for pregnant women in precarious situation. METHODS: A retrospective observational study took place between November 2013 and May 2015 in a type III Parisian maternity. Comparison of sociodemographic, perinatal and postpartum characteristics of women in precarious situations (no stable housing and no social care or universal medical coverage or state medical aid) was done according to whether they were included in the system PRENAP or not. RESULTS: Over the study period, 344 (4.6%) women in precarious situations gave birth in this maternity. Among these women, the women included in the PRENAP system were more frequently in a very unfavorable social situation than those who were not included. The inclusion in the PRENAP device did not reduce the hospitalization in post-partum. Breast-feeding was chosen more frequently by the women included in the PRENAP device. CONCLUSION: The PRENAP device seems to favor the use of breast-feeding, but is not associated with a diminution of the hospitalization time in post-partum. This social device, which seems to be beneficial in terms of social and medical support for women in precarious situations, deserves to be evaluated prospectively.
