ABSTRACT To assess the presence of insomnia and sleepiness and related factors in the late third trimester of pregnancy.
A total of 370 singleton gravids completed a general questionnaire containing personal data, the Insomnia Severity Index (ISI) and the Epworth Sleepiness Scale (ESS). In addition, maternal anthropometry was recorded upon survey.
Median [interquartile range] maternal age and gestational age upon survey was of 31 [7.0] years and 39 [1.8] weeks, respectively. A 73.5% of women displayed some degree of insomnia (Total ISI score 8-28) and 22.2% sleepiness (Total ESS score ≥10). Determined rho Spearman coefficients showed significant correlations between ISI scores and gestational age at survey and survey to birth interval (weeks) and between ESS scores and maternal weight and arm circumference at survey and neonatal birth weight. Multiple linear regression analysis found that smoking habit, higher blood pressure and shorter survey to birth interval (weeks) significantly predicted higher ISI scores, and hence a higher risk of insomnia. Employed status, increased arm circumference and neonatal weight predicted higher ESS scores (sleepiness).
Insomnia and sleepiness were prevalent in the late third trimester of pregnancy in which lifestyle factors and maternal and neonatal body composition were significant predictors.

    ABSTRACT: Insufficient sleep is common in the general population, and can result from environmental and psychosocial factors, medical and psychiatric disorders, and sleep disorders, such as insomnia, circadian rhythm disorders, sleep apnoea and restless legs. Women are particularly at risk for sleep disorders, and complaints of sleep disturbance are more prevalent among women than men across the life span. During the perinatal period, many common sleep disorders, such as obstructive sleep apnoea or restless legs may be exacerbated, or in the case of insomnia or narcolepsy, treatment options may change. In addition, the role of circadian rhythms in fertility and perinatal health is just beginning to be appreciated. In this chapter, we provide an overview of the current knowledge of the unique aspects of diagnosis and treatment of sleep disorders during the perinatal period.

    ABSTRACT: Abstract Objective: Sleep deficiency is an emerging concept denoting a deficit in the quantity or quality of sleep. This may be particularly salient for pregnant women since they report considerable sleep complaints. Sleep deficiency is linked with morbidity, including degradations in psychosocial functioning, (e.g., depression and stress), which are recognized risk factors for adverse pregnancy outcomes. We sought to describe the frequency of sleep deficiency across early gestation (10-20 weeks) and whether sleep deficiency is associated with reports of more depressive symptoms and stress. Methods: Pregnant women (N=160) with no self-reported sleep or psychological disorder provided sleep data collected via diary and actigraphy during early pregnancy: 10-12, 14-16, and 18-20 weeks' gestation. Sleep deficiency was defined as short sleep duration, insufficient sleep, or insomnia. Symptoms of depression and stress were collected at the same three time points. Linear mixed effects models were used to analyze the data. Results: Approximately 28%-38% met criteria for sleep deficiency for at least one time point in early gestation. Women who were sleep deficient across all time points reported more perceived stress than those who were not sleep deficient (p<0.01). Depressive symptoms were higher among women with diary-defined sleep deficiency across all time points (p=0.02). Discussion: Sleep deficiency is a useful concept to describe sleep recognized to be disturbed in pregnancy. Women with persistent sleep deficiency appear to be at greater risk for impairments in psychosocial functioning during early gestation. These associations are important since psychosocial functioning is a recognized correlate of adverse pregnancy outcomes. Sleep deficiency may be another important risk factor for adverse pregnancy outcomes.

    ABSTRACT: 141 United States. 1 The prevalence of breathing disturbance without reported symptoms is even higher, especially in individuals old-er than 50. 2 It is also a cause of increased mortality among young patients. 3 The role of OSA in the pathogenesis and mortality of cardiac disease has been established in multiple studies. 4-9 All cause-mortality in OSA patients increases with age, BMI, and male sex. 3 In a recent meta-analysis, Loke et al. found an increased likelihood stroke (OR=2.24; 95% confidence interval [CI], 1.57-3.19), with the most significant associa-tion seen in men. 10 Apnea hypopnea index (AHI) was also increased in patients with cardiovascular incidents in a recent study performed by Chami et al. 11 The authors examined the relationship of OSA severity to cardiovascular morbidity in 2721 partici-pants, from the Sleep Heart Health Study co-hort. The study participants were followed for five years and tested with two polys-omnograms to evaluate disease progression over time. An increase in obstructive apnea-hypopnea indices over time was associated with more frequent cardiovascular disease. After excluding patients with central apnea, the participants with cardiovascular disease an AHI increase by 1.75 obstructive event per hour was found in the individual with Effects of sleep loss and selected sleep disorders on health and disease Loss of sleep can result from multiple medi-cal and psychiatric conditions as well as from primary sleep disorders. Large epidemiologi-cal studies indicate that obstructive sleep apnea a higher risk of stroke and cardio-vascular disease. Insomnia, as well as sleep restriction may increase worsen cardiac dis-ease. Metabolic consequences of poor sleep include higher risk of diabetes and obesity. Parasomnias may be seen in association with various conditions, for example of REM be-havior disorder is frequently associated with Parkinson's disease.
