BACKGROUND Physical and hormonal changes during pregnancy alter breathing patterns of pregnant women. It is possible that occult disordered breathing during sleep may be a risk factor for the development of pregnancy-induced hypertension (PIH) and preeclampsia. OBJECTIVE Our aim was to determine the incidence of self-reported snoring in pregnant women, and to investigate the relationship of s...

Snoring is an acoustic phenomenon, which is a consequence of vibrations of the soft tissue caused by partial obstruction of the upper breathing pathway while sleeping. It is estimated that 20% of men and 5% of women between 30 and 35 years of age snore and this rate increases to 50% of men and 30% of women over 60 years of age. The aim of this study was to evaluate the efficiency of radiofreque...

STUDY OBJECTIVES This report describes the associations, specificities, sensitivities, and positive likelihood ratios of clinical symptoms to a finding of sleep-disordered breathing (SDB) on polysomnography in children. METHODS Four hundred eighty unattended home polysomnograms were completed in a community-based cohort of children 6 to 11 years of age (50% boys, 42.3% Hispanic, and 52.9% bet...

BACKGROUND Neurobehavioural symptoms of inattention and hyperactivity are common in children with sleep-disordered breathing (SDB). Prevalence rates of habitual snoring and attention deficit hyperactivity disorder (ADHD) are very similar and both have a substantial negative effect on children's behavioural health. OBJECTIVE We examined the differences for subjective attentional and hyperactiv...

To evaluate sleep quality, it is necessary to be able to accurately measure and analyze sleep disorders such as snoring or apnea. In recent years, sleep care applications and devices have been introduced, but accurate measurement techniques are required because these applications and devices do not take users’ snoring intensity and characteristics into consideration. In this paper, we proposed ...

OBJECTIVE To track the development of sleep disordered breathing (SDB) as well as dento-facial morphology in cohort of children by having them complete a questionnaire at ages 4, 6 and 12. Clinical examination, sleep studies (at ages 4 and 12) and orthodontic evaluation were carried out on all who were reported to snore regularly and children who did not snore at all. RESULTS Out of the origi...

OBJECTIVE The prevalence of obstructive sleep apnea OSA has not been assessed in Saudi Arabia. We aimed to assess the prevalence of individuals who were at risk of OSA in a sample of middle-aged Saudi males, using the Berlin questionnaire at primary care settings. METHODS The study was conducted at King Khalid University and King Fahd National Guard primary health care clinics in Riyadh, King...

BACKGROUND Nasal congestion at night is thought to have a role in snoring and sleep apnea, but this hypothesis has not previously been tested in a population-based study. METHODS Baseline and 5-year follow-up data on self-reported nocturnal nasal congestion and snoring frequency were collected from a population-based sample of 4916 men and women (age range, 30-60 years at baseline) enrolled i...

Snoring, a symptom which may indicate the presence of the obstructive sleep apnoea syndrome (OSA), is also common in the general population. Recent studies have suggested that the acoustic characteristics of snoring sound may differ between simple snorers and OSA patients. We have studied a small number of patients with simple snoring and OSA, analysing the acoustic characteristics of the snori...

BACKGROUND Habitual snoring, a prominent symptom of sleep-disordered breathing, is an important indicator for a number of health problems in children. Compared to adults, large epidemiological studies on childhood habitual snoring and associated predisposing factors are extremely scarce. The present study aimed to assess the prevalence and associated factors of habitual snoring among Chinese sc...
