“…Similarly, Ayrim and colleagues studied 200 pregnant women and 200 age-matched controls, using a questionnaire that includes questions regarding snoring, witnessed apnea, sleepiness and neck circumference. They found that although the incidence of snoring appears to increase during pregnancy, especially in women who gain excessive weight, there is no effect of fetal outcome [29]. These findings were confirmed by a study on 276 women from Korea [30].…”

Pregnancy is associated with profound changes in sleep. Up to 75% of pregnant women experience some form of sleep disruption during pregnancy. The emerging data from recent years suggests that sleep disturbances may represent a novel contributor to adverse pregnancy outcomes and that sleep disorders during pregnancy may affect both maternal and fetal outcomes. In spite of the increased awareness, information specifically addressing sleep disturbances and fetal outcomes is limited. The current review summarizes the existing published literature on the effect of short sleep duration, poor quality sleep and sleep-disordered breathing (SDB) on the developing fetus.

“…1 SDB, independent of maternal BMI, is associated with an increased risk of hypertension in pregnancy, as well as maternal morbidity. 73,78,[80][81][82][83][84][85][86] In one study, preeclampsia, a hypertensive syndrome in pregnancy, was significantly more common among snorers than non-snorers (10% versus 4%, p < 0.05), as was gestational hypertension (14% versus 6%, p < 0.01). 87 This was recently corroborated in a report by O'Brien and colleagues, who found that pregnancy-onset snoring was independently associated with gestational hypertension (OR 2.36 [1.48-3.77], p < 0.001) and preeclampsia (OR 1.59 [1.06-2.37], p = 0.024) in 1,719 third-trimester pregnant women.…”

Sleep disturbances in the general population are associated with elevated blood pressure. This may be due to several mechanisms, including sympathetic activation and hypothalamic-pituitary-adrenal (HPA) axis disturbance. Elevated blood pressure in pregnancy can have devastating effects on both maternal and fetal health and is associated with increased risk for preeclampsia and poor delivery outcomes. Preliminary evidence suggests that mechanisms linking sleep and blood pressure in the general population may also hold in the pregnant population. However, the effects of disturbed sleep on physiologic mechanisms that may directly infl uence blood pressure in pregnancy have not been well studied. The role that sleep disturbance plays in gestational blood pressure elevation and its subsequent consequences warrant further investigation. This review evaluates the current literature on sleep disturbance and elevated blood pressure in pregnancy and proposes possible treatment interventions. T he association between sleep disturbances and elevated blood pressure has been extensively studied in the general population. However, relatively few studies have investigated this relationship in the pregnant population. Pregnancy predisposes women to a variety of sleep disturbances.1,2 Similar to non-pregnant individuals, sleep disturbance in pregnancy may be a risk factor for elevated blood pressure, which can lead to maternal and fetal morbidity . 3,4Gestational hypertension, defi ned as a blood pressure higher than 140/90 diagnosed after 20 weeks of gestation, is associated with fetal growth restriction and abruptio placentae and can predispose to preeclampsia, as well as cardiovascular disease later in lif e. 1,[4][5][6] There are few studies evaluating the link between sleep and blood pressure during pregnancy. In this paper, we fi rst review the relationship between sleep and blood pressure in non-pregnant adults. We then outline factors that predispose pregnant women to poor sleep. We conclude with a review of the emerging literature on the associations between sleep and blood pressure in pregnancy. SLEEP AND BLOOD PRESSURE IN THE NON-PREGNANT POPULATIONIn the U.S. the average sleep duration has decreased by 1.5-2 h/night, with > 30% of Americans sleeping < 6 h/night. 7This phenomenon and the concurrent increase in hypertension intimated a possible link between sleep duration and blood pressure. Recently, a series of epidemiological papers have noted an association between sleep duration (both short and long) and elevated blood press ure [8][9][10][11] ; for example, the Sleep Heart Health Study reported that participants who slept < 5 or ≥ 9 h/night had a greater frequency of hypertension than individuals sleeping

“…Sleep characteristics may change very early during pregnancy due to endocrine and anatomical modifications. As pregnancy continues, sleep duration decreases and the prevalence of insomnia, sleep-related breathing disorders, restless leg syndrome and sleepiness significantly increases [6][7][8]. Pregnancy may also aggravate an existing sleep disorder [9].…”
