Roll-over test in primigravidae attending a public primary care service

Abstract

Objective:To determine the roll-over test (ROT) performance in predicting pregnancy-induced hypertension (PIH) in primigravidae aged 15-29 years in a public primary care service. Method: Prospective cohort study enrolling 369 consecutive and initially normotensive primigravidae. The ROT was applied within 28-32 weeks of pregnancy. PIH was defined as diastolic blood pressure (DBP) 90 mm Hg or systolic blood pressure (SBP) 140 mm Hg, or a rise in DBP 15 mm Hg or a rise in SBP 30 mm Hg. The ROT prognostic properties were calculated, and a receiver operating characteristic (ROG) curve was constructed. Results: For the 20 mm Hg cutoff point, sensitivity was 20% and specificity was 93%. Positive and negative predictive values were, respectively, 23% and 92%, for a PIH cumulative incidence of 9.5%. With other cutoff points, the ROG curve showed a poor discriminatory value of the test. ConcliJsion: The ROT was not useful for predicting PIH in a primary prenatal care setting.Uniterms: Pregnancy.

Validity Study of the Roll-Over Test and Risk Factors for Preeclampsia in Four Health Districts of Surigao City, Philippines

“…A much earlier study conducted in 1997 at Sao Paolo, Brazil by Marcopito et al involving 369 pregnant women revealed a much lower sensitivity of the roll-over test at 20% (7/35) and a specificity of 93% (311/334). 29 No maternal deaths or serious complications was observed during the duration of this study. However, a major limitation is the higher probability of suffering from a confounding factor bias being a cross-sectional study compared to a repeated measure or longitudinal study design.…”
