Insights

Poor sleep quality significantly increases the risk of childhood obesity. Children with poor sleep were 8.6 times more likely to be obese, highlighting sleep

Area of Science:

  • Pediatric Health
  • Obesity Research
  • Sleep Science

Background:

  • Rising global obesity rates necessitate understanding contributing factors.
  • Childhood obesity is a growing concern, with average sleep duration in Indonesian children at 6-7 hours.
  • Sleep quality is increasingly recognized as a potential driver of obesity.

Purpose of the Study:

  • To investigate the association between sleep quality and obesity prevalence in school-aged children.
  • To determine if poor sleep quality is a risk factor for childhood obesity.

Main Methods:

  • Prospective cohort study involving 37 primary school children (grades 4-6).
  • Snowball sampling technique used for participant recruitment from West Java and Sumatra.
  • Data collected via Pittsburgh Sleep Quality Index (PSQI) and one-month sleep logs.

Main Results:

  • 63.2% of obese children reported poor sleep quality, versus 83.3% of non-obese children reporting good sleep quality.
  • Chi-square analysis revealed a statistically significant correlation (p=0.011) between sleep quality and obesity.
  • Poor sleep quality was associated with an 8.6-fold increased likelihood of obesity (OR=8.571, 95% CI: 1.818-40.423).

Conclusions:

  • Sleep quality is significantly correlated with obesity in school-aged children.
  • Poor sleep quality is a substantial risk factor for developing childhood obesity.
  • Habitual sleep efficiency emerged as the most dominant factor linked to childhood obesity (OR=12.354).

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

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.

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...

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

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...

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...
