Risk factors for maternal mortality: Results of a case-control study conducted in Conakry (Guinea)

Objective: To assess the risk factors of maternal mortality in an urban area of West Africa (Conakry, capital of Guinea). Method: A case-control study where 102 maternal deaths were compared with 338 control women who had given birth and survived, during 1 year (from July 1, 1989 to June 30, 1990). Result: Of all the socio-demographic variables studied, only a low family income (R = 2.6; 1.1–6.5) was found to be a risk factor for maternal death In the obstetrical part of the survey, neither parity nor the number or location of pre-natal consultations constituted risk factors. However, the presence during pregnancy or delivery of signs of infection (R = 3.7; 1.4–9.8), anemia (R = 2.1; 1.1–4.1), hypertension (R = 19.8; 5.8–67.8) and dystocia (R = 9.0; 3.7–21.5) were found to be the main predictive risk factors of maternal death. The maternal mortality risk was multiplied by 12 if the woman had had a cesarean section, and by 4 in the case of complications in the post-partum period. Conclusion: To achieve substantial reductions in maternal mortality levels, work must be done on these specific risk factors, and future programs must urgently be concentrated on a higher standard of pre-natal monitoring, obstetrical emergency facilities and training of obstetrical staff.
