ABSTRACT
Objective To understand the vitamin D status and its possible ethnic differences among Uygur and Han women of childbearing age in a community of Urumqi.Methods Based on the data of 2 080 patients with thyroid disease in a community of Urumqi,which were collected in May 2013,we selected the complete information of 652 Uygur and Han women of childbearing age (between 18-45 years),which included 367 Uygur women [average age (35.14± 6.91) years] and 285 Han women [average age (35.52± 7.10) years].The basic data of height,weight,and waist circumference were recorded.The serum level of 25-hydroxyl vitamin D [25(OH) D] was detected by chemiluminescence method.Results The serum 25(OH) D levels of Uygur and Han were (11.51±6.31) μg/L and (16.43±6.43) μg/L,respectively.The 25(OH)D level in Uygur women was significantly lower than that of Han women (t =-9.800,P＜0.001).The constituent ratio of vitamin D status was significantly different between Uygur and Han women (vitamin D severe deficiency:47.4％ in Uygur women and 12.3％ in Han women),deficiency (44.7％ in Uygur women and 64.6％ in Han women),insufficiency 5.7％ in Uygur women and 17.9％ in Han women),sufficiency (2.2％ in Uygur women and 5.2％ in Han women) (x2 =99.486,P＜0.001).Conclusion Serum 25 (OH) D deficiency is common in Uygur and Han women of childbearing age in Urumqi,especially among Uygur women.
