To determine the utilization of maternal health care services and pregnancy outcomes for women with a history of complications in previous pregnancy, we analysed the pregnancy records of multiparous women (parity > or =1) who booked and completed follow-up in Gutu district, Zimbabwe between January 1995 and June 1998. Women with previous uncomplicated pregnancies (n = 6140) were classified as low risk, whereas those with complications of previous pregnancy (n = 1077) were classified high risk. At enrolment, there was no difference in maternal age and parity between low- and high-risk women. A higher proportion of high-risk women had more than five antenatal visits (32% versus 21%; P<0.001) and gave birth in hospital (47% versus 18%; P<0.001). The risk of antenatal (relative risk [RR] 1.57; 95% confidence interval [CI] 1.32-1.88), labour/delivery (RR 1.98; 95% CI 1.75-2.25) and neonatal (RR 1.83; 95% CI 1.44-2.34) complications was elevated in high-risk women. There was increased risk for perinatal death in high-risk women, but this did not reach statistical significance (RR 1.56; 95% CI 0.98-2.49). The recurrence ratio for most complications was low and the sensitivity of historical risk markers in predicting women likely to develop further complicated pregnancies was only 23%. Most women with previous pregnancy complications can safely give birth in the rural health centre. We concluded that high-risk women had an elevated risk of complications in the index pregnancy and that better utilization of maternal health care, especially for delivery, reduced adverse perinatal outcomes.

    ABSTRACT: Preeclampsia occurs in about 4 per cent of pregnancies worldwide, and may have particularly serious consequences for women in Africa. Studies in western countries have shown that women with preeclampsia in one pregnancy have a substantially increased risk of preeclampsia in subsequent pregnancies. We estimate the recurrence risks of preeclampsia in data from Northern Tanzania. A prospective cohort study was designed using 19,811 women who delivered singleton infants at a hospital in Northern Tanzania between 2000and2008. A total of 3,909 women were recorded with subsequent deliveries in the hospital with follow up through 2010. Adjusted recurrence risks of preeclampsia were computed using regression models. The absolute recurrence risk of preeclampsia was25%, which was 9.2-fold (95% CI: 6.4 - 13.2) compared with the risk for women without prior preeclampsia. When there were signs that the preeclampsia in a previous pregnancy had been serious either because the baby was delivered preterm or had died in the perinatal period, the recurrence risk of preeclampsia was even higher. Women who had preeclampsia had increased risk of a series of adverse pregnancy outcomes in future pregnancies. These include perinatal death (RR= 4.3), a baby with low birth weight (RR= 3.5), or a preterm birth (RR= 2.5). These risks were only partly explained by recurrence of preeclampsia. Preeclampsia in one pregnancy is a strong predictor for preeclampsia and other adverse pregnancy outcomes in subsequent pregnancies in Tanzania. Women with previous preeclampsia may benefit from close follow-up during their pregnancies.
