Insights

This study found that sleep bruxism in children is linked to sleep difficulties and lower socioeconomic status, but not screen time. Further research is needed to understand these associations.

Area of Science:

  • Pediatric Sleep Medicine
  • Child Health Epidemiology

Background:

  • Sleep bruxism (SB) is a common condition in children, affecting their oral health and sleep quality.
  • Factors influencing SB prevalence in pediatric populations require further investigation.

Purpose of the Study:

  • To determine the prevalence of probable sleep bruxism (SB) in 7-8-year-old children.
  • To examine the association between probable SB, sleep patterns, and screen time.

Main Methods:

  • A cross-sectional study involved 556 children aged 7-8 years in Pelotas, Brazil.
  • Data collected via parental interviews and the BRIAN-K-sleep domain questionnaire.
  • Probable SB diagnosed through clinical inspection and/or parental reports of tooth grinding/clenching.

Main Results:

  • The prevalence of probable SB was 15.83%.
  • No association found between probable SB and daily screen time (p=0.744).
  • Low socioeconomic status (PR=1.95) and higher sleep domain scores on BRIAN-K (PR=1.07) were associated with probable SB.

Conclusions:

  • Difficulties in maintaining sleep and low family socioeconomic status are associated with probable SB in schoolchildren.
  • Screen time was not found to be associated with probable SB in this age group.

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

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.
