[Perinatal care and mortality in French Guyana. From 1992-1999].

Background: The purpose of this study was to describe child deliveries in French Guyana and describe changes in perinatal mortality in different population groups between 1992 and 1999.

Material And Methods: All deliveries in health centers and maternity wards in French Guyana between January 1, 1992 and December 31, 1999 were included in the study. Social, demographic, and clinical data were collected at the time of delivery. Infants with a birth weight of 500 g or term 22 weeks were included.

Results: From 1992 to 1995, the number of deliveries in health centers declined 5.7% and the number in public maternity wards increased 69.7%. The same trend was observed in 1998 - 1999 (2.4% and 85.7% respectively), an expression of the policy of antenatal referral implemented by the network of childbirth professionals. Perinatal mortality decreased significantly between 1995 and 1998 from 35.4 to 15.2 for the Creole population (p=0.06), from 46 to 16.5 for the Black-Marron Surinam population (p<0.0007), and from 36 to 10.2 for the Black-Marron French population (p<0.009). This drop in mortality in high-risk population groups may have contributed to the overall decline in perinatal mortality observed over the study period. The rate of preterm birth remained stable (at 13.5%) and the proportion of low-weight infants increased only slightly (12.8% to 13.7%). Mortality among preterm infants declined considerably, undoubtedly because of improved neonatal intensive care.

Conclusion: Despite significant improvement, the perinatal mortality in French Guyana (18.9 in 1999) remains almost three times that in metropolitan France (7.4 in 1999). The mothers are young (17% aged less than 20 years) and the proportion of primiparous and grand multiparous mothers is high. With the absence or insufficiency of prenatal care, the problem of perinatal mortality remains a public health priority and challenge in French Guyana.
