探讨髂棘上部褶厚、腹部褶厚与骨密度(BMC)及骨矿量(BMD)的相关关系,测量287例汉族志愿者髂棘上部褶厚、腹部褶厚及全身各个部位的BMC和BMD。采用偏相关分析法(partial分析)探索褶厚同BMC及BMD的相关关系。结果显示:髂棘上部褶厚及腹部褶厚同全身总骨密度(r分别为0.229和0.201)、上肢密度(r分别为0.175和0.150)、下肢密度(r分别为0.245和0.198)、躯干密度(r分别为0.299和0.261)、肋骨矿量(r分别为0.324和0.267)、骨盆密度(r分别为0.341和0.293)、脊柱密度(r分别为0.220和0.194)在控制性别和年龄的影响后均显著正相关(所有的P<0.05)。髂棘上部褶厚及腹部褶厚同全身总矿量(r分别为0.281和0.235)、上肢矿量(r分别为0.182和0.137)、下肢矿量(r分别为0.326和0.269)、躯干矿量(r分别为0.296和0.247)、肋骨密度(r分别为0.322和0.279)、骨盆矿量(r分别为0.290和0.235)、脊柱矿量(r分别为0.245和0.221),在控制性别和年龄的影响后亦均显著正相关(所有的P<0.05)。研究结果提示髂棘上部褶厚及腹部褶厚增加所反应的腹部脂肪含量增加及腹部肥胖可能增加骨量,进而间接对骨质疏松症的发生起保护作用。
To investigate the relationship between upper iliac crease thickness, abdominal fold thickness and bone mineral density (BMC) and bone mineral content (BMD), and to investigate the relationship between the BMC and BMD in 287 Han volunteers . Partial correlation analysis was used to explore the relationship between pleat thickness and BMC and BMD. The results showed that the upper pleura thickness and abdominal pleat thickness of the iliac crest were the same as those of the whole body (r = 0.229 and 0.201, respectively), upper limb density (r = 0.175 and 0.150 respectively), lower limb densities (r = 0.245 and 0.198, (r = 0.299 and 0.261, respectively), rib mass (r = 0.324 and 0.267, respectively), pelvis density (r = 0.341 and 0.293, respectively) and spine density (r = 0.220 and 0.194, respectively) after controlling for gender and age There was a significant positive correlation (all P <0.05). The total volume of iliac crest folds and abdomen folds were 0.281 and 0.235 (r = 0.182 and 0.137, r = 0.182 and 0.137, respectively), while the amounts of lower extremities (r = 0.326 and 0.269, (r = 0.296 and 0.247, respectively), rib density (r = 0.322 and 0.279, respectively), pelvic mineral content (r = 0.290 and 0.235, respectively) and spine volume (r = 0.245 and 0.221, respectively) After the effects were also significantly positively correlated (all P <0.05). The results suggest that an increase in the thickness of the upper iliac crest and an increase in the thickness of the abdomen increases the abdominal fat content and abdominal obesity may increase the amount of bone, which indirectly plays a protective role in the occurrence of osteoporosis.
