概括

调整食物时间与你的生理时钟对青少年的身体组成有好处. 具体来说,晚年时代型的青少年的晚餐时间与脂肪自由质量指数 (FFMI) 的增加有关.

科学领域:

营养科学营养科学
时间生物学时间生物学
儿科健康儿科健康

背景情况:

睡眠-清醒周期 (时型) 的个体差异影响日常行为,包括饮食模式.
与个体的时间型相比,饮食的时间,特别是最高的热量摄入量,是一个新兴的研究领域.
了解这种关系对于青少年健康至关重要,因为他们具有独特的发育阶段和长期健康轨迹的潜力.

研究的目的:

评估青少年中最高热量摄入时间和个体时间型之间的对齐.
调查这种饮食调整与青少年身体组成指标之间的关联.

主要方法:

利用了来自DONALD队列研究的196名青少年 (9-16岁) 的纵向数据.
使用慕尼黑时刻型问卷评估时刻型来推导睡眠的中点 (MSFsc).
根据个人和人口中位时间最高热量摄入量之间的偏差计算了饮食-时间对齐得分 (DCAS),调整为时间型.
采用重复测量回归模型来分析DCAS和身体组成之间的关联 (例如,脂肪质量指数,无脂肪质量指数).

主要成果:

饮食-时间对齐得分 (DCAS) 显示了广泛的范围 (-6:42小时至+8:01小时),并且通常与身体组成无关.
然而,在晚期时代型 (n=201) 的青少年中,DCAS (后期最高热量摄入量) 的1小时增加与脂肪自由质量指数 (FFMI) 在大约0.94年内增加1.92公斤/米2显著相关.
对于脂肪质量指数 (FMI) 没有发现任何显著的关联.

结论:

将最高热量摄入量与个体的年代型对齐,可能有利于脂肪自由质量指数 (FFMI),特别是在晚年年代型的青少年中.
这些发现表明,时间型指导的饮食时间在青春期优化身体组成方面可能发挥作用.

Signs of Puberty

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Cognitive Development During Adolescence

Cognitive Development During Adolescence

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

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...
