背景情况:
- 心脏代谢风险因素和氧化应激标志物对于评估儿童心血管健康至关重要.
- 在青春期前期了解这些标志物的性别特异性对于早期干预至关重要.
- 第二十一代出生队列为研究儿童长期健康趋势提供了有价值的人口.
研究的目的:
- 调查前青春期儿童中氧化应激,氧化 (NO) 生物可用性和心脏代谢风险因素的性别相关差异.
- 为了确定氧化还原标记,NO生物可用性和心脏代谢健康指标之间的潜在的特定性别关联.
主要方法:
- 一项对313名青春期前儿童 (8-9岁) 的横截面研究.
- 评估了人体测量,心脏代谢变量和氧化还原标记,包括异质 (Isop),总抗氧化状态 (TAS),髓氧化酶 (MPO),酸盐/亚酸盐 (NOX) 和过氧化 (H2O2).
主要成果:
- 女孩的总胆固醇,甘油三和胰岛素耐药性 (HOMA-IR) 比男孩高.
- 男孩的尿液中过氧化 (U-H2O2) 和尿液中酸盐/酸盐 (U-NOX) 含量较高,特别是在超重/肥胖的人群中.
- 多变量分析显示,男孩的U-H2O2与脉冲波速率之间,以及男孩的U-NOX与脂质样本之间存在反向关联,而女孩则显示尿液异构素 (U-Isop) 与HOMA-IR之间存在积极关联.

Obesity
507
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...

Signs of Puberty
365
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)...

Psychoneuroimmunology: Cardiovascular Disease
31
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
