Comparison of Central and Peripheral Bone Mineral Density Measurements in Postmenopausal Women
1Biomechanics Department, Faculty of Physical Therapy, Cairo University, Giza, Egypt.
Objectives:
The purpose of the current study was to compare central and peripheral bone mineral density at different regions including spine, hip, and wrist in postmenopausal women.
Methods:
Forty postmenopausal women participated in this study. Their mean age, body mass, height, and body mass index were 53.5 ± 2.75 y, 68.6 ± 8.68 kg, 167.8 ± 6.46 cm, and 24.31 ± 1.69 kg/m2, respectively. Bone mineral density (BMD) T-scores of spine, hip, and wrist regions were measured for all participants with a dual-energy X-ray absorptiometry scan.
Results:
All measured regions (spine, hip, and wrist) had low BMD T-scores. Bone mineral density of the wrist was significantly lower (-2.58 ± 2.18) than that of both spine (-1.79 ± 0.98) and hip (-1.69 ± 1.37). In addition, there were no statistically significant differences in BMD between the spine and hip.
Conclusions:
In this group of postmenopausal women, wrist BMD decreased more than spine and hip BMD. Both spine and hip BMD decreased by nearly the same percentage in postmenopausal women. Peripheral sites may be more representative of osteoporosis than central sites. Trial Registration: PACTR201602001478123.

01:29Bone 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...

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...

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
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...
