EVALUATION OF ISOMETRIC EXERCISE TEST an‎d ROLL-OVER TEST AS METHODS OF PREGNANCY INDUCED HYPERTENSION PREDICTION

Background: The incidence of pregnancy induced hypertension (PIH) which is one of the three main causes of maternal-neonatal morbidity and mortality is 5-7%, and prediction of this disorder is very important in maternal and neonatal health. Methods: The type of this study is analytical (comparative-prospective) and its purpose is to evaluate the isometric exercise test (IET) and roll-over test (ROT) as methods of PIH prediction. 116 nulliparaes, with study characteristics, after filling a questionnaire and physical exam, underwent ROT, and then IET after 5 minutes, between 28-32 weeks of their pregnancy. The samples are followed up regularly until 24 hr after delivery in Mashad university prenatal clinics and hospitals. Statistical analysis was done by SPSS with a: 0.05. Results: As a result, IET has a higher validity than ROT (sensitivity: 78.9% vs.47.4%, p<0.0001 specificity: 94.80vs. 83.5%,p: 0.007,positivepredictivevalue:75% vs. 36%, p: 0.0001, negative predictive value: 95.8% vs. 89%, p: 0.046), also validity of IET and ROT together is: sensitivity: 85.7%, specificity: 96.3%, PPV: 66.6% and NPV: 98.8%. Conclusion: The validity of IET in this study was shown to be higher than ROT, and by use of a very simple and cost-effective IET, we are able to predict PIH with the highest validity and if possible, use both tests in order to raise validity.
