口服避孕药 (OCP) 的使用与更高的骨矿物密度 (BMD) 和女性骨质疏松症风险降低有关. 这表明潜在的长期骨健康益处,可能降低晚年骨质疏松症并发症.
科学领域:
- 内分泌学 在内分泌学.
- 老年学是一门学科.
- 骨健康研究 骨健康研究
背景情况:
- 骨质疏松性骨折是因雌激素损失而导致绝经后妇女残疾的主要原因.
- 含有雌激素的口服避孕药 (OCP) 对骨健康和骨质疏松症风险的长期影响尚未完全理解.
研究的目的:
- 调查口服避孕药 (OCP) 使用与骨矿物质密度 (BMD) 之间的关联.
- 评估OCP使用对女性患骨质疏松症风险的影响.
主要方法:
- 利用英国生物库数据从257185名妇女 (出生于1936-1970).
- 使用时间依赖的考克斯回归用于骨质疏松风险和多变量线性回归用于骨质疏松 (T-scores).
- 分析了骨的定量超声波,以评估骨质量.
主要成果:
- 曾经使用过OCP的患者骨质疏松症的发病率较低 (HR=0.86;P<2.8×10−17).
- 使用OCP与更高的BMDT分数 (0.052;P<2.1×10−12) 相关联,在更长的时间内,益处增加.
- 对于使用OCP的2-5岁,6-10岁,11-15岁和16岁以上的人,观察到与BMD有显著的积极关联.
结论:
- 之前使用OCP与改善骨矿物质密度有关.
- 使用OCP似乎可以降低骨质疏松症的风险,这表明潜在的长期保护作用.
- 使用OCP可能有助于减轻老年妇女的骨质疏松并发症.

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...
Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Birth Control Methods
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Bone Remodeling
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...
