Summary
This summary is machine-generated.This study found that in young Japanese adults, shorter sleep duration is linked to obesity, while longer sleep duration is associated with being underweight. These findings highlight the complex relationship between sleep patterns and body mass index (BMI).
Area Of Science
- Public Health
- Sleep Medicine
- Nutritional Science
Background
- Existing research links sleep disorders and short sleep duration to obesity.
- Limited and inconsistent evidence exists regarding the association between sleep duration and underweight.
- Investigating sleep duration's impact on both underweight and obesity is crucial for public health.
Purpose Of The Study
- To examine the relationship between sleep duration and Body Mass Index (BMI) in a young Japanese population.
- To determine the prevalence of underweight and obesity in relation to sleep duration.
Main Methods
- A cohort of 12,496 university students in Japan participated.
- Data on sleep duration, sleep disorders, and lifestyle factors were collected via self-reported questionnaires.
- Logistic regression analysis was employed to assess associations between sleep duration and BMI categories, controlling for confounders.
Main Results
- Prevalence rates were 14.3% for underweight (BMI <18.5) and 10.5% for obesity (BMI ≥25).
- Short sleep durations (<7 hours) were positively associated with obesity, while longer durations (≥9 hours) showed an inverse association.
- Longer sleep durations (≥6 hours) were positively associated with underweight, with significant trends observed for durations of 8-9 hours and ≥9 hours.
Conclusions
- Sleep duration demonstrated a significant positive association with underweight and an inverse association with obesity in young Japanese adults.
- Findings suggest distinct relationships between sleep duration and different BMI categories in this demographic.
- Further research is warranted to elucidate the mechanisms underlying these associations.

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.

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,...
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...
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
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:
Stage 1 is...
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...
