“…The insomnia in our study was more prevalent in the T2, presenting itself different from the existing literature which is not unanimous about the period of higher prevalence 15 .We did not investigate the reasons for this occurrence, however it could be associated to the late psychological perception of pregnancy in the studied population. Most pregnant women arrive at the Health Public Services for care when already in the 2 nd trimester of pregnancy, suggesting that only in this period women begin to realize the responsibilities and changes that are happening or are about to happen in their lives.…”

ABSTRACT:Context: The precise function of sleep in animals and human beings is still unknown, and any sort of physical, social or psychological variation may change the normal sleep-wake cycle. Purpose: This research aims is to determine the sleep disorders (SD) for each of the three trimesters of the pregnancy comparing them to the pre-pregnancy state (PG). Method: SD were investigated in three hundred pregnant women 11-to 40-years-old through with a brief clinical interview based on directed questions. One hundred pregnant women were considered for each trimester. Results: The rate of pregnant women with insomnia increased by 23% in the 2 nd trimester (p< 0.005); the rate for excessive daytime sleepiness (EDS) by 15% in the 1 st trimester (p<0.003), 55% in the 2 nd trimester (p<0.001) and by 14% in the 3 rd trimester (p<0.002); the rate for mild sleepiness increased by 33% in the 2 nd trimester (p<0.002) and by 48% in the 3 rd trimester (p<0.001); the rate for specific awakenings increased by 63% in the 1 st trimester, by 80% in the 2 nd trimester and by 84% in the 3 rd trimester (p<0.001). Conclusion: SD were more frequent during pregnancy comparatively to PG state, mostly at the expenses of EDS and specific awakenings.KEY WORDS: pregnancy, sleep disorders, awakening, insomnia, excessive daytime sleepiness. Distúrbios do sono na gravidezRESUMO -Introdução: A função exata do sono em animais e seres humanos ainda é desconhecida e qualquer variação física, social ou psíquica pode alterar o ciclo normal de sono e vigília. Objetivo: O objetivo desta pesquisa é detectar os principais distúrbios do sono (DS) nos três trimestres da gravidez comparando-os ao estado pré-gestacional (PG). Método: Os DS foram investigados em 300 gestantes com idades variando de 11 a 40 anos, através de breve entrevista com questões dirigidas. Foram incluídas 100 gestantes para cada trimestre. Resultados: A proporção de grávidas com insônia aumentou 23% no 2º trimestre (p<0,005); a de sonolência intensa 15% no 1º trimestre (p<0,003), 55% no 2º (p<0,001) e 14% no 3º (p<0,002); a de sonolência leve 33% no 2º trimestre (p<0,002) e 48% no 3º (p<0,001); a de despertares específicos 63% no 1º trimestre, 80% no 2º e 84% no 3º (p<0,001). Conclusão: DS foram mais freqüentes durante a gravidez comparativamente ao PG, principalmente às custas de sonolência intensa e despertares específicos. PALAVRAS-CHAVE: gravidez, distúrbios do sono, despertar, insônia, sonolência excessiva diurna.It is not known the precise function of sleep in animals and human beings. The main explanation considers the need to replenish individual's energy (physical and psychological).The restoration provided by sleep seems to be an important component, once it is preceded by fatigue and usually followed by feelings of satisfaction.When there is an impossibility to sleep well, restrictions in day functioning or excessive daytime sleepiness (EDS) may occur 1-2 . Physical, emotional and social variations in human beings' life may induce sleep disorders as insomnia and EDS. The gr...

“…Suzuki et al found that that among 192 pregnant women surveyed retrospectively, 88% had alterations in sleep compared with their usual experience. 62 The reported changes included insomnia, parasomnias (nightmares and night terrors), restless leg syndrome (RLS), snoring, and sleep apnea. Among the most frequent self-reported causes of sleep disturbance during pregnancy were urinary frequency, back or hip ache, and heartburn.…”

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

“…However, there are few studies about the relationship between low back pain and sleep disorders in populations of pregnant women. In research conducted with 192 pregnant women, Suzuki et al (8) observed that pain at the lower back and at the hips, in association with fetal movements, interfere on sleep and reduce the alertness during daytime.…”

Introduction: Pregnancy is characterized by several changes in her body. These changes contribute to the emergence of low back pain, which may influence the quality of sleep during pregnancy. Objective: To compare the quality of sleep among pregnant women with and without low back pain during pregnancy, examining the relationship between two variables. Materials methods: Thirty volunteers aged between 19 and 36 years, divided into control group (CG -n = 16) and Study Group (SG -n = 14), residents in the cities of Natal, were evaluated in the second trimester of pregnancy. To sleep evaluation were used to index the Pittsburgh Sleep Quality and the Epworth Sleepiness Scale. Low back pain was evaluated using the pressure algometer, Visual Analogue Scale (VAS) and Oswestry Disability Index. Statistical analysis used the Shapiro Wilk test, Student's T test for independent samples and Pearson correlation test. Results: The mean gestational and chronological ages were 28.2 ± 3.4 years and 19.9 ± 3.7 weeks, respectively. Sleep quality was lower in SG (8.21 ± 4.8) when compared to CG (5.94 ± 1.7) and was statistically significant (P = 0.021). Analyzing the relationship between sleep quality and pain intensity, it was observed that the variables have a positive correlation between them
