A research study focused on ‘Sleep and vigilance disorders in pregnancy’ revealed that the overall effect of sleep disorders increase during all trimesters of pregnancy.The research was conducted at the Department of Neurology, CHU La Miletrie, Poitiers, France.

Objectives of this study included evaluation of frequency of sleep disorders like sleep apnea disorder, insomnia, restless leg syndrome, and daytime sleepiness according to three defined trimesters of pregnancy. In orders to study and evaluate the effects of sleep disorders like sleep apnea and daytime sleepiness researchers selected 871 young pregnant women on random basis.

The research study was based on a cross-sectional design and included retrospective survey of pre-pregnancy stage, symptoms, and prospective survey of current symptoms. Researchers used questionnaires and interviews to derive inferences. Alterations in the sleeping patterns of mothers were analyzed to evaluate their sleep before pregnancy and sleeping patterns during different trimesters of pregnancy.

Researchers observed that in almost 75% of these pregnant women the rate of increase of insomnia, sleep apnea, non-refreshing sleep, and frequent awakening during the second and third trimester was considerably higher.

“Reasons for such increase are mainly attributed to the factors like an urge to urinate, fetus movements, backache, and restless leg syndrome”, say the researchers.

Researchers also found that more than 18% of these pregnant women were suffering from snoring every night and this rate was on increase during all trimesters of pregnancy.

On the other side, almost 75% of these pregnant women also complained about a significant reduction in their overall vigilance. These women also expressed that their need to nap has increased during the pregnancy.

The research concluded with findings that subjective quality of sleep starts getting frequently disturbed from the first trimester of the pregnancy and then keeps increasing throughout the second and third trimesters of pregnancy with an exception of day time sleepiness which was observed more frequent only during the first trimester of pregnancy.
