RESUMEN
Early delivery is not rare, it is an important cause of perinatal mortality. In this study its rate, was 4.95%. The early and late ages of procreation were particularly interested (7.95%) and 3.90%. The first and last parities were more exposed (7.75%-5.31%). The woman occupation was as an important risk-factor. The incidences increased in the poor and rich women groups (7.34%-3.84%) the early labor risk was reduced when the women had efficient prenatal care; when the women had delivered early, the early labor risk increased. So when the women had delivered a stillborn. The early labor risk factor was more important. Finally the authors founded 83.33% of maternal causes could be controlled by efficient prenatal care. Even this rate was so important in the foetal group causes.
PIP: An important cause of perinatal mortality, premature delivery involves the expulsion of the fetus during weeks 28-37 of gestation. Such deliveries are seen rather often, but its frequency varies by country and in the same country from one time period to the next. Results are presented from a study on the frequency and epidemiology of premature deliveries at Ignace Deen Hospital in Conakry between May 1994 and June 1995. This prospective study was conducted using hospital documents. Of 2057 births, 102 were premature, for a frequency of 4.95%. Adolescents, women aged 35 years and older, primiparous women, and grand multiparas ran the greatest risks of bearing a premature child. The risk of premature delivery was 3.8 times greater in the group of housewives than in the group of salaried women, and 2.45 times more than among students. The highest incidences of premature delivery were among poor and wealthy women, at the respective levels of 7.54% and 3.84%. The absence of prenatal care was an important risk factor, with the risk of premature delivery decreasing as the degree of prenatal follow-up increased. Having already had a premature birth and a stillbirth multiplied by 7.86 and 12.58, respectively, the risk of premature delivery. 83.33% of maternal factors involved in premature delivery could have been controlled using effective prenatal care.
