Objective:

To determine the effectiveness of the roll-over test as a predictor of pre-eclampsia.

Methodology:

The studied population had a size of 272, with a sample of 262 pregnant women, between 28 and 32 weeks of gestational age, who obtained pre-natal care at the Guillermo Almenara Irigoyen National Hospital, between January and September of 2017. The ROC curve, and the sensitivity and specificity of the roll-over test to predict pre-eclampsia, were calculated.

Results:

The prevalence of the roll-over test in this study was 9%, with a 95% confidence interval (5.43 - 12.22). In this study, the ROC curve was determined (0.725 and 0.734, for the first and second measurements, respectively) and found to be statistically significant at the p <0.05 level. The sensitivity of the roll-over test for a cutoff point of 20 mmHg was 60%, and the specificity of 95% also had a PPV of 37% and a NPV of 98%. Differences between the first and second measurements suggest that the second measurement is more sensitive than the first one.

Conclusions:

The roll-over test is a simple, cost-effective test with potential application in initial evaluation of pre-eclampsia in pregnant women with a history of pre-eclampsia and/ or other risk factors.
