RESUMO
A recent study at the Maroua Provincial Hospital revealed that hypertension in pregnancy was the first cause of maternal death, representing 17.5% of the 63 maternal deaths recorded between 2003 and 2005. Knowing little about the causes, this study was to identify the possible risk factors for hypertensive disorders in pregnancy. This case-control study was-done at the Maroua Regional Hospital, Cameroon between June 2005 and May 2007. All the 152 deliveries complicated with hypertension were compared and analyzed with 414 pregnancies that were not complicated with the disease. Data analysis was performed using EPI Info 3.5.1. The differences were considered to be significant if the p-values were less than 0.05. Using univariate analysis, several factors linked to hypertensive disorder in pregnancy were identified. They included early adolescence, nulliparity, illiteracy, lack of occupation and family history of hypertension. At multivariate analysis, the risk of having hypertension during pregnancy remained greater for illiterate women [OR: 1.6; 95%CI: 1.0-2.3], housewives [OR: 2.8; 95%CI: 1.1-6.9], nulliparae [OR: 2.8; 95%CI: 1.5-3.6], women with family histories of hypertension [OR: 3.6; 95%CI: 1.6-8.5] and women with histories of hypertension during pregnancy [OR: 7.0; 95%CI: 3.0-16.4]. Risk factors for hypertensive diseases in pregnancy in Maroua, Cameroon seem to include early teenage status, illiteracy, housewife status, nulliparity and family or personal histories of hypertension. The knowledge about the aforesaid factors seems to lay the tracks for its prevention in Cameroon
