Hypertension during pregnancy in Africa and infants' health. A cohort study in an urban setting.
J Perinat Med. 1993; 21(1):13-24.JP

Abstract

The objective of the study was to assess the prevalence of unclassified hypertension during pregnancy and its consequences on infant's health in an African urban setting: Pikine, a suburb of Dakar, Senegal. A cross-sectional study of a random sample of pregnant women and a prospective study, from the inclusion to seven days after delivery, were performed. 886 women attending the prenatal centers were included in the cross-sectional study. 471 pregnant women were included in the follow-up study. The prevalence of DBP > or = 120 mmHg was 0.7%; 5.7% of the women had DBP > or = 95 mmHg. Longitudinal data were available for 425 deliveries. Two spontaneous abortions, 25 stillbirths, and 12 deaths during the early neonatal period were recorded. Among babies living at birth, the percentage of LBW (> or = 2500 g) was 8.5%. The percentages of adverse outcome of pregnancy (death and/or low birth weight) was associated with mothers' diastolic BP: < 85 mmHg: 13%; 85 to 89: 16%; 90 to 94: 9%; DBP > or = 95: 32%, (p < 0.01). Using 95 mmHg as a cutpoint, the relative risk of adverse outcome associated with a DBP > or = 95 mmHg was 2.5 (CI 95%: 1.4-4.3). This risk was significantly increased among women who reported difficult living conditions. Eight percent of the adverse outcomes of pregnancy, 10% of the low birth weights and 8% of the perinatal mortality were found to be associated with DBP > or 95 mmHg.
