pregnancy; sleep; balance.
During pregnancy, there hemodynamic, hormonal changes and biomechanical the female body, resulting in changes in maternal body systems. The changes in the pattern and deprivation sleep characteristics of this period, affecting postural stability these women. The aim of this study was to compare the variables postural balance (static and dynamic) among pregnant women, and no change in sleep pattern (excessive sleepiness, hours overnight stays per night and latency), according to the quarters gestational. The study included 236 pregnant women aged gestational between 16 and 32 weeks (M= 25.03, SD= ± 4.49). Of these, 124 (52.4%) were in the second trimester and 112 (47.5%) in the third. The volunteers were assessed for standard sleep through the index of the Pittsburgh Sleep Quality and Epworth Sleepiness Scale. For assessment of the balance postural, was used Balance Master System®. Data were analyzed by Student's t-test for independent samples. As objective of controlling the interference of gestational age on postural balance, comparisons were made, separately, considering the trimesters of pregnancy. Was adopted a significance level of P<0.05. The results showed that 27.7% of the evaluated consider how good the quality of sleep and 72.5% classified as poor quality of this. It was also checked that 55.9% of pregnant women showed no excessive sleepiness, in contrast to 39.4% of the volunteers who showed such condition.
