The associations between peak bone mineral density (BMD) and body composition with 25 hydroxyvitamin D (25OHD) levels in healthy young adults were evaluated.
The number of participants was 464; 347 women and 117 men. The mean age was 24.3 years (range 17-31 years). BMD of the lumbar spine, total body and femoral neck (FN) and body composition were measured by dual energy X-ray absorptiometry. Volumetric BMD, bone mineral apparent density (BMAD), of the lumbar spine and FN was calculated.
In females, 25OHD level was positively associated with FN BMD and BMAD (both p<0.01) and negatively with percentage body fat (p<0.001). In males, 25OHD levels had a positive association with total body BMD and lean body mass (p=0.03 and p=0.01).
25OHD level is a determinant of peak BMD in both sexes. Vitamin D status was associated with body fat in females and with lean body mass in males.
评估健康年轻成年人的峰值骨密度(BMD)和身体成分与25羟维生素D(25OHD)水平之间的关联。
参与者有464人,其中347名女性和117名男性。平均年龄为24.3岁(范围17 - 31岁)。采用双能X线吸收法测量腰椎、全身和股骨颈(FN)的骨密度以及身体成分。计算腰椎和FN的体积骨密度、骨矿物质表观密度(BMAD)。
在女性中,25OHD水平与FN骨密度和BMAD呈正相关(均p<0.01),与体脂百分比呈负相关(p<0.001)。在男性中,25OHD水平与全身骨密度和瘦体重呈正相关(p = 0.03和p = 0.01)。
25OHD水平是男女峰值骨密度的一个决定因素。维生素D状态在女性中与体脂有关,在男性中与瘦体重有关。
