Insights

Nocturnal enuresis (NE) prevalence was 4.6% in primary school children, with boys affected more. NE was not linked to obstructive sleep apnea (OSA) overall, but increased with OSA severity in girls.

Area of Science:

  • Pediatric Sleep Medicine
  • Urology
  • Public Health

Background:

  • Nocturnal enuresis (NE) is common in children.
  • Obstructive sleep apnea (OSA) is increasingly recognized in pediatric populations.
  • The relationship between NE and OSA requires further investigation.

Purpose of the Study:

  • To determine the prevalence and associated factors of NE in primary school children.
  • To compare NE prevalence in children with and without OSA.
  • To explore the association between OSA severity and NE.

Main Methods:

  • A community-based study involving 6147 children aged 6-11 years.
  • Parental questionnaires collected data on sleep symptoms, demographics, and medical history.
  • Polysomnography (PSG) was performed on a subset of children screened for OSA risk.

Main Results:

  • The overall prevalence of NE was 4.6%, higher in boys (6.7%) than girls (2.5%).
  • NE prevalence was not significantly higher in children with OSA.
  • In girls, NE prevalence increased with OSA severity; boys with NE had longer deep sleep duration.

Conclusions:

  • NE prevalence in primary school children is associated with sex.
  • A link between NE and OSA severity was observed in girls.
  • Sleep-related symptoms and sex are significant correlates of NE.

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
Nightmares often...
Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...
Narcolepsy01:07

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...
