RESUMO

Objective - To evaluate possible changes in the amniotic fluid index (AFI) among pregnant women practicing moderate physical activity in water immersion. Method: a prospective study was performed, comparing the AFI pre and post immersion in water for physical activity. Pregnant women from the Pre Natal Outpatient Clinic in the hospital of the University of Campinas who accepted to participate in the study on physical activity during pregnancy were selected. They were randomly allocated in two groups (with and without water aerobic, respectively group A and B). The women in group A practiced moderate physical activity in water under subtotal immersion, three times a week, in sessions of 50 minutes each, in swimming pool heated at 30º C, from the second trimester of pregnancy until delivery. Women with history of two or more cesarean sections, high risk pregnancy or conditions contra-indicating physical activity practice (hypertension, placenta previa, history of recurrent abortions, etc.) were excluded. The women were evaluated weekly with an ultrasound exam in order to estimate the pre and post immersion AFI and also a clinical screening for edema. A second examiner also obtained the AFI values in order to evaluate the inter observer variability. For statistical analysis the programs Epi.Info 2000 and SAS were used. The quantitative variables were compared with Student t or non parametric Wilcoxon test. For evaluation of inter observer variability of the measures, the linear correlation coefficient was used. A 5% significance level was previously determined. Results: a total of 25 pregnant women participated in the study between May 2003 and December 2004, with age ranging from 19 to 36 years and 232 ultrasound evaluations of pre and post immersion AFI, with a mean of 9.28 exams per woman. An increase in the post immersion AFI compared to pre immersion was observed in all gestational ages studied, ranging from 8.8 and 21.5%. These changes were significant for the vast majority of gestational ages and there was not a significant trend of increase or decrease of this difference with gestational age. There was a good agreement on pre and post immersion AFI values between both examiners, with a correlation coefficient of respectively 0.78 and 0.70. The edema of legs was detected in around 23% of weekly observations after 29 weeks and decreased after immersion. Conclusions: there was a significant increase of AFI in almost all gestational ages, then the treatment of immersion in water for increasing the AFI could be effective
