老年营养风险指数 (GNRI) 是骨质疏松症和骨质疏松症患者死亡率的关键预测指标. 较低的GNRI得分显著增加了全因和心血管死亡的风险.
科学领域:
- 老年医学 老年医学
- 营养科学 营养科学
- 骨健康研究 骨健康研究
背景情况:
- 骨质疏松症和骨质疏松症是普遍存在的骨疾病.
- 营养状况越来越被认为是影响老龄人口健康结果的因素.
研究的目的:
- 研究老年营养风险指数 (GNRI) 与骨质疏松症和骨质疏松症患者的死亡率之间的关联.
- 为了确定GNRI是否预测在这个特定的人群中所有原因和心血管疾病 (CVD) 死亡率.
主要方法:
- 来自NHANES (2005-2019) 的6824名患有骨质疏松症/骨质疏松症的参与者的数据分析.
- 参与者分为GNRI的第三类.
- 统计分析包括拟合曲线,卡普兰-梅尔曲线,考克斯回归和子组分析.
主要成果:
- 较低的GNRI三位体与年龄较大,男性性别和并发症增加有关.
- 在GNRI和死亡率之间观察到一个显著的反向J形关系.
- 最低的GNRI三位数显示所有原因死亡风险增加了1.6-2倍,即使经过调整.
- 在心血管疾病死亡率方面也观察到类似的趋势.
结论:
- 老年营养风险指数 (GNRI) 是骨质疏松症和骨质疏松症患者死亡率的重要预后因素.
- 在较低的GNRI水平和所有原因和心血管疾病死亡率的风险增加之间存在明确的剂量反应关系.
- GNRI是评估患有骨密度状况的患者死亡风险的宝贵工具.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
