背景:

スマートフォンの問題使用 (PSU) は,若者の間で懸念が高まっています.
睡眠パターンや個人の違いなど,PSUに影響を与える要因を理解することは極めて重要です.

研究の目的:

スマートフォンの使用時間とPSUの関係におけるクロノタイプと睡眠時間の抑制作用を調査する.
PSUのリスクが高い特定の睡眠とクロノタイプを特定する.

主な方法:

2018年の韓国児童・若者パネル調査の二次分析 (N=3,919).
クロノタイプ,睡眠時間,スマートフォンの使用,問題のあるスマートフォンの使用 (PSU) の評価.
PROCESS マクロモデルを用いたモデレーションとモデレーションされたモデレーション分析で,共変数を制御する.

主要な成果:

スマートフォンの使用とPSUとの関連性は,クロノタイプと睡眠期間によって著しく緩和されました.
スマートフォンの使用とPSUの間のポジティブな関連性は遅い時間型と遅い時間型の両方で増幅されました
スマートフォンの使用とPSUの間の負の相関は,特に高度なクロノタイプで示されました.

結論:

スマートフォンの使用とPSUの関係に影響を与える重要な要因は睡眠期間とクロノタイプです
健康的な睡眠とスマートフォンの習慣を促進する介入は,親と学校に推奨されています.

Insufficient Sleep and Sleep Deprivation

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 Sleep

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,...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

What is an Experiment?

What is an Experiment?

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...

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Management of Insomnia

Management 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...
