RESUMO

Objective: To assess the effect of physical exercise with stationary cycling on the incidence of preeclampsia (PE), blood pressure (BP), heart rate (HR) and quality of life (QoL) in pregnant women with chronic high blood pressure (CHB), and/or previous preeclampsia pregnancies. Methods: A randomized controlled clinical trial in 52 pregnant women whom presented with risk factors (CHB, PE in prior pregnancy) for preeclampsia development between January 2008 and September 2009. The participants were selected from prenatal ambulatory services at Campinas State University (UNICAMP), Women´s Health Integral Attention Centre (CAISM). The participants were randomly allocated in two groups: a treatment group in which women did physical exercises using a stationary bicycle once a week under physiotherapist supervision, at Physiotherapy Department of CAISM/UNICAMP and the control group, which followed a regular prenatal routine of weekly returns for HR and blood pressure (BP) measurements. Both groups completed the quality of life survey (Short Form Health Survey - SF-36) on three separated occasions during the study period: at enrollment between 12 and 20 gestational weeks, between 28 and 32 gestational weeks and between 36 and 41 gestational weeks. To test the homogeneity, a student t-test was used for continuous variables of normal distribution, the Mann-Whitney test for non-normal distribution variables and the Fisher s Exact test was used for nominal variables. Intervention effect in time, and between group BP and HR s were assessed through ANOVA. The statistically significance was assumed as 5%. Results: The comparative analysis between groups demonstrated no statistical differences in blood pressure and HR. However, within the intragroups assay (control and study), the initial and final moment blood pressures revealed statistical differences. Both groups had decreased scores in some QoL survey domains, but there were no statistically significant differences when scores were compared between the groups. Conclusion: Women at risk for preeclampsia development, which performed physical exercise using a stationary bicycle did not show preeclampsia (present in three cases in control group), neither HR and BP changes, and the use of a stationary cycling program was shown to be a safe modality in this population when properly supervised. However, they shown worse QoL score results in some domains when related to gestational evolution. Further studies need to be done with larger sample sizes to confirm the hypothesis that PE can be prevented when physical exercise is performed in at risk pregnant populations
