Summary
Using electronic devices (EDs) before bed significantly harms sleep quality in Vietnamese university students. Limiting ED use near bedtime is crucial for improving student sleep health.
Area of Science:
- Public Health
- Sleep Medicine
- Digital Health
Background:
- Electronic device (ED) use before bedtime is a growing public health concern impacting sleep quality.
- University students represent a demographic with high ED usage and potential sleep disturbances.
Purpose of the Study:
- To investigate the association between pre-sleep electronic device (ED) use and sleep quality among Vietnamese university students.
- To identify specific ED usage patterns and other lifestyle factors linked to poor sleep.
Main Methods:
- A cross-sectional study involving 369 university students from three departments.
- Self-report surveys assessed demographic characteristics, lifestyle, ED-use behaviors, sleep quality (Pittsburgh Sleep Quality Index), and depression (Center for Epidemiologic Studies Depression Scale).
Main Results:
- Nearly half (48.8%) of students reported poor sleep quality.
- Over 98% used at least one ED daily within two hours of bedtime, primarily smartphones (92.3%).
- Pre-sleep ED use, duration over 30 minutes, lack of exercise, alcohol consumption, late-afternoon coffee intake, and depression were significantly associated with poorer sleep quality.
Conclusions:
- Pre-sleep electronic device use, particularly for over 30 minutes, is a significant independent predictor of poor sleep quality in university students.
- Interventions promoting restricted ED use before bedtime and healthy lifestyle habits are essential for improving sleep quality in this population.

01:13Insufficient Sleep and Sleep Deprivation
296
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.

01:24Substance Use Disorders Affecting Sleep
240
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.

01:12What is an Experiment?
16.0K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

01:53Cause and Effect
11.6K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

01:19Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

283
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
