Risk factors for premature birth in French Guiana: the importance of reducing health inequalities
Résumé
Objectives: French Guiana has the highest birth rate in South America. This French territory also
has the highest premature birth rate and perinatal mortality rate of all French territories. The
objective was to determine the premature birth rate and to identify the prevalence of risk factors
of premature birth in French Guiana.
Methods: A retrospective study of all births in French Guiana was conducted between January
2013 and December 2014 using the computerized registry compiling all live births over 22
weeks of gestation on the territory.
Results: During this period 12 983 live births were reported on the territory. 13.5% of newborns
were born before 37 (1755/12 983). The study of the registry revealed that common sociodemographic
risk factors of prematurity were present. In addition, past obstetrical history was also
important: a scarred uterus increased the risk of prematurity adjusted odds ratio ¼1.4, 95%CI
(1.2–1.6). Similarly, obstetrical surveillance, the absence of preparation for birth or of prenatal
interview increased the risk of prematurity by 2.4 and 2.3, the excess fraction in the population
was 69% and 72.2%, respectively.
Conclusions: Known classical risk factors are important. In the present study excess fractions
were calculated in order to prioritize interventions to reduce the prematurity rate.
