We investigated factors implicated in the development of pregnant high blood pressure risks and fetal-maternal repercussions. Were evaluated (Age, Gestity, Childbirth type, Eclampsia, Gestational diabetes, Overweight, TA/S, TA/D, Baby’s weight). The logistic model retained, age of mother (OR = 1.17, 95% CI = 1.08-1.27, P < 0.001). The gestity (OR = 2.94, 95% CI = 2.16 - 04.01, P < 0.001. A systolic blood pressure greater than 90 mmHg is at risk (OR= 11.29, 95 % Cl = 1.91 -66.78, P= 0.008).A diastolic blood pressure greater than 140 mmHg (OR = 15.84, 95% CI = 2.67- 66.78, P = 0.002). Gestational diabetes (OR = 2.89, 95% CI = 1.65 - 5.06, < 0.001). The overweight (OR = 25.31, 95% CI = 18.45 - 34.71, P < 0.001). Fetal repercussions are hypotrophy and perinatal mortality. The model established has a very high forecast capacity.
