背景:
- 産後の骨代謝は,母乳育児によって著しく変化します.
- アジアの女性の母親のカルシウム摂取量と骨の回復に関する研究は限られている.
研究 の 目的:
- 産後の骨のミネラル密度 (BMD) の変化を調査する.
- 哺乳状態に基づいて,カルシウム摂取量とBMD回復の関連性を調べる.
主な方法:
- 36人の女性 (22人の母乳育児,14人の非母乳育児) は,3つの時間点でDXA経由でBMDを評価しました.
- 食事中のカルシウム摂取量は,食品頻度アンケートとサプリメントを使用して評価されました.
- 線形回帰では,カルシウム摂取量と,骨髄膜質量 (%ΔBMD) の変化の%との関連を分析した.
主要な成果:
- 授乳は複数の部位でBMDの有意な低下をもたらし,授乳しない女性は6ヶ月で股関節頸部BMDの増加を示した.
- 産後カルシウム摂取量は,乳児を哺乳しない女性の総部および股関節頸部における%ΔBMDと正の相関関係を示した.
- 授乳中の女性では12ヶ月でBMDが出産レベルに回復し,授乳しない女性は6ヶ月レベルを維持した.
結論:
- 産後カルシウム摂取は,授乳しない女性の骨の回復に影響を及ぼします.
- 骨の回復に対するカルシウム摂取量の影響は,授乳状態によって異なる場合があります.

01:40Bone Remodeling
40.6K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:29Bone Disorders
5.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...

01:17Hormones and Bone Tissue
3.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...

01:25Role of Vitamins in Maintaining Bone Health
5.7K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
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...

01:21Skeleton and Calcium Homeostasis
6.1K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

01:31Essential Minerals for Bone Health
6.6K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
