Abstract

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.
