A survey of parentally reported sleep health disorders in Estonian 8-9 year old children.

Background: Pediatric sleep research is rather new in Estonia. There has not been a comprehensive study of age specific sleep disorders in Estonian children. The aim of this study was to investigate sleep disorders in a sample of Estonian second grade children.

Obstructive sleep apnea syndrome (OSAS): Pathophysiology in Estonians.

The aim of the study was to clarify the roles of age, obesity, smoking, alcohol, pathoanatomy and -physiology in Estonian's OSAS. For this 164 randomly chosen such patients were selected in different regions of Estonia. They underwent naso-oropharyngeal examination, physical examination of craniofacial abnormalities, and polysomnography.

Symptoms of anxiety and depression in Estonian medical students with sleep problems.

High emotional stress in medical students has been observed in many studies. Our aim in this article was to assess the prevalence of symptoms of anxiety and depression among Estonian medical students and to find relationships between sleep complaints and emotional symptoms. The study group consisted of 413 medical students, ages 19-33 years, at the University of Tartu.

Sleep quality and more common sleep-related problems in medical students.

Background And Purpose: The aim of this paper is to conduct a survey based on a questionnaire that would characterize nighttime and daytime habits in medical students; to estimate how subjective sleep quality is associated with nighttime and daytime habits and sleep problems in students; to estimate how academic progress and workload is associated with subjective sleep quality, nighttime and daytime habits and sleep problems in students; and to estimate the prevalence of self-reported sleep problems in Estonian medical students.

Patients And Methods: The study group included 413 medical students of the University of Tartu, aged 19-33 years. The self-reported Sleep and Daytime Habits Questionnaire (S&DHQ) covered demographic characteristics (4 questions) and sleep and daytime habits (24 questions).

Obstructive sleep apnea and ageing Myotonometry demonstrates changes in the soft palate and tongue while awake.

Upper airway dilator muscles are important in the pathogenesis of obstructive sleep apnea syndrome (OSAS). The present study compares changes of tissue properties between the soft palate and tongue in different age groups of apnea patients and healthy subjects. Materials and methods: OSAS patients diagnosed by polysomnography (15 patients - aged 30-70 years; 10 patients - aged 18-29 years) and healthy volunteers (10 subjects - aged 30-70 years; 10 patients - aged 18-29 years) participated in the study.

Myotonometry demonstrates changes of lingual musculature in obstructive sleep apnoea.

Upper airway dilator muscles are important in the pathogenesis of obstructive sleep apnoea (OSA). Previously, soft palate and tongue muscles of patients with OSA have been studied from a histological point of view. Electromyographic studies revealed increased activity of upper airway dilator muscles.
