概括
坚持24小时运动指南,包括睡眠和屏幕时间,与儿童腰部与身高比率变化减少有关. 需要更多的干预措施来改善对指南的遵守,以获得更好的儿童健康结果.
科学领域:
- 儿科健康与营养学
- 公共卫生和流行病学
- 儿童肥胖研究儿童肥胖研究
背景情况:
- 儿童肥胖症是一个日益严重的全球性问题,近几十年来患病率越来越高.
- 现有研究表明,遵守24小时运动指南是有益的,但纵向研究很少.
- 以前的研究经常使用横截面设计,限制了对因果关系的理解.
研究的目的:
- 为了前性地研究遵守24小时运动指南 (睡眠时间,屏幕时间和中度至强度的体力活动) 与儿童肥胖的变化之间的关联.
- 调查睡眠,屏幕时间和体育活动指南的联合遵守对一年内的各种脂肪指标的影响.
- 提供关于运动行为与学龄儿童肥胖之间的关系的纵向证据.
主要方法:
- 一项纵向研究涉及中国杭州8-12岁的202名儿童.
- 使用加速度计 (用于MVP) 和问卷 (用于睡眠和ST) 对24小时运动指南的基线评估.
- 脂肪指标的测量 (BMI z-score,体脂百分比,腰与身高比) 在基线和1年后的随访,使用一般线性或多级模型进行分析.
主要成果:
- 只有6.9%的儿童满足了所有三个运动指南.
- 遵守所有三个指南或睡眠和屏幕时间指南与腰与身高比率 (ΔWHtR) 的预期变化较低有关.
- 遵守睡眠指南与BMI z-score (ΔBMIz) 的潜在变化较低有关,而遵守MVPA与较高的 ΔBMIz有关. 对于身体脂肪百分比 (ΔBF%) 没有发现显著的关联.
结论:
- 坚持24小时运动指南,特别是睡眠和屏幕时间,显示出与腰与身高比率变化减少的潜在关联.
- 虽然睡眠坚持可能有利于BMIz,但MVPA坚持与增加BMIz有悖论的联系,突出了这些关系的复杂性.
- 干预措施对于加强儿童遵守全面的24小时运动指南至关重要,以减轻肥胖变化.

Longitudinal Research
11.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Obesity
353
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...

Longitudinal Studies
101
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Attention-Deficit/Hyperactivity Disorder
34
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....

Lung Capacity
48.7K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
