Comparison of bone mineral density and serum trace elements between Uygur young and elderly women in Urumqi / 中国组织工程研究

ABSTRACT

BACKGROUND:Estrogen promotes the storage of trace elements in the bones and thereby impacts the variation of bone mineral density through influencing the bone cel metabolism. OBJECTIVE: To study the difference of bone mineral density and serum trace elements between Uygur young and elderly females from Urumqi. METHODS:The bone mineral density was measured in the Uygur women aged 30 to 40 years and 60 to 70 years in Urumqi by dual-energy X-ray absorptiometry made in MEDILINK. The serum levels of trace elements, including calcium, phosphorus, magnesium, iron, copper, zinc, were measured by Unicel Dxc 800 Synchron biochemical test instrument produced by Beckman Kurt, USA. Serum levels of trace elements and bone mineral density were compared between two groups. RESULTS AND CONCLUSION:Compared with the elderly group, the bone mineral density was significantly higher but the serum level of zinc was lower in the young group (bothP 0.05). These findings indicate that the bone mineral density of Uygur women at different age is significantly correlated with a part of trace elements in serum.
