概括
饮食中的抗氧化剂显著降低了中国成年人的血压 (BP) 和高血压风险. 较高的抗氧化剂摄入量,通过总抗氧化能力 (DTAC) 和饮食抗氧化剂质量评分 (DAQS) 来衡量,与较低的血压和降低患高血压的几率相关.
科学领域:
- 营养科学 营养科学
- 心血管健康 心血管健康
- 公共卫生 公共卫生
背景情况:
- 饮食中抗氧化剂对血压 (BP) 调节和高血压风险的影响尚未得到充分证实.
- 高血压是全球主要的健康问题,需要对饮食等可修改的危险因素进行研究.
研究的目的:
- 综合评估饮食中抗氧化剂对缩血压 (SBP),腹缩血压 (DBP),平均动脉压 (MAP) 和脉冲压 (PP) 的影响.
- 评估饮食中抗氧化剂摄入量与中国成年人高血压风险之间的关联.
主要方法:
- 一项涉及12046名中国成年人的横截面研究.
- 饮食抗氧化剂质量评分 (DAQS) 和总抗氧化剂容量 (DTAC) 用经过验证的食物频率问卷进行了评估.
- 使用多变量逻辑回归分析了DAQS,DTAC和高血压患病率之间的关系.
主要成果:
- 与摄入量最低的参与者相比,具有最高DTAC和DAQS的参与者显示SBP,DBP,MAP和PP显著较低 (p趋势<0.001).
- 较高的DTAC和DAQS五分位数与高血压的几率大幅降低有关 (例如,Q5 DTAC或0.38,Q5 DAQS或0.38).
- 增加维生素A,和的摄入量与较低的高血压风险相关.
结论:
- 富含抗氧化剂的饮食与血压参数 (SBP,DBP,MAP,PP) 的明显降低有关.
- 较高的饮食抗氧化剂摄入量显著降低了患高血压的风险.
- 侧重于抗氧化剂的饮食干预措施是预防和管理高血压的有希望的策略.

1.9K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
