| Research Abstract |
The resting autonomic modulations in the women during late pregnancy were evaluated by heart rate variability (HRV) measures in relation to factors related to quality of life (sleep, mental health, fatigue), and significant impact was suggested in sleep. Our next cross-sectional study of 160 women investigating associations between sleep disturbances and HRV measures demonstrated that the resting autonomic modulations shifted toward a sympathetic predominant state in the women who are habitual snorers. Our further study of 64 pregnant women evaluating overnight oxygen saturation suggested that parasympathetic activity of the resting autonomic modulations is attenuated in women who underwent profound oxygen desaturation. The resting autonomic modulations in the pregnant women may be affected by sleep-disordered breathing, and it is important to evaluate the background factors of the autonomic dysfunctions prior to interventions to improve autonomic functioning in the pregnant women.
