We monitored blood pressure (BP) for a 24-h period in type 1 diabetic women at each trimester of pregnancy (10-13, 20-22, and 30-33 weeks of gestation) to identify early alterations of BP profile in pregnancies complicated by hypertension.


We prospectively studied 71 type 1 diabetic pregnant women and 48 nondiabetic pregnant women (homogeneous by age and pre-pregnancy BMI) consecutively recruited at 10+/-2 weeks of pregnancy in the space of 2 years (1999-2000). They were all normotensive (<130/80 mm Hg) and normoalbuminuric (AER<20 microg/min) at entry to the study.


Analysis of variance (ANOVA) and simple regression and chi(2) were applied as appropriate by an Apple software program (Stat View).


In diabetic women, we recorded higher levels of diastolic BP (even if within a normal range) at each time point; diabetic vs. nondiabetic women: first trim daytime diastolic BP: 71.35+/-8.75 vs. 67.7+/-9.7, P=.01; second trim nighttime diastolic BP: 62.15+/-6.45 vs. 58.05+/-6.7, P=.05; third trim nighttime diastolic BP: 66.03+/-8.72 vs. 60.7+/-6.5, P=.01. Among diabetics, those who later developed pregnancy-induced hypertension (36.6%) showed significantly higher values of BP at the first and third trimester compared to those who remained normotensive. In the two groups, there were no differences in age and pre-pregnancy BMI by contrast of diabetes duration (hypertensive vs. normotensive, 19.18+/-7.3 vs. 14.35+/-9.1 years, P=.03) and age of diagnosis (hypertensive vs. normotensive, 9.6+/-5.5 vs. 14.7+/-8.6 years, P=.01). Positive correlation was found between fasting blood glucose and diastolic BP at each trimester of pregnancy.
