Comparação do equilíbrio postural entre mulheres com e sem alteração do padrão de sono no segundo e terceiro trimestres gestacionais

Abstract

Introduction: During pregnancy, hemodynamic, hormonal, and biomechanical changes occur in the female body that result in changes in maternal body systems. Changes in sleep pattern and deprivation, characteristics of this period, can affect the postural stability of these women. Aims: To compare the variables of postural balance (static and dynamic) among pregnant women, with and without alteration of the sleep pattern (excessive sleepiness, hours of sleep per night and latency) according to the gestational trimesters. Methods: A total of 236 pregnant women with a gestational age ranging from 16 to 32 weeks (25.03; SD± 4.49) participated in the study. Of these, 124 (52.4%) were in the second and 112 (47.5%) in the third gestational trimester. The volunteers were assessed for sleep pattern using the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. Balance Master was used to evaluate postural balance. Data were analyzed by Student's t-test for independent samples. A significance level of p <0.05 was adopted. Results: The results showed that 56 pregnant women (27.7%) considered it as good and 171 (72.5%) rated sleep quality as poor. It was also verified that 132 pregnant women (55.9%) did not present excessive drowsiness, as opposed to 93 volunteers (39.4%) who demonstrated such condition. Conclusion: There were no significant differences in postural balance variables between pregnant women with and without alteration of the sleep pattern in both gestational trimesters.
