To explore the effects of being overweight on lumbar spine (L2-L4) and femoral neck (FN) bone mineral apparent density (BMAD) in a group of Lebanese adolescent girls.
Forty-two Lebanese postmenarchal adolescent girls participated in this study (22 overweight [BMI > 25 kg/m2] adolescent girls [15.4 +/- 2.4 years old] and 20 maturation-matched [15.2 +/- 1.9 years old] controls [BMI < 25 kg/m2]). Body composition and bone mineral density (BMD) were measured with dual-energy X-ray absorptiometry (DXA). Calculation of the BMAD was completed for the FN and for the L2-L4. FN and L2-L4 BMAD values were higher (p < 0.01) in overweight girls compared to normal-weighted girls. In the whole population, fat mass was a positive determinant of L2-L4 and FN BMAD (p < 0.001 and p < 0.05 respectively).
In this study group, being overweight is associated with higher L2-L4 and femoral neck BMAD values.
探讨超重对一组黎巴嫩青春期女孩腰椎（L2-L4）和股骨颈（FN）骨矿物质表观密度（BMAD）的影响。
42名黎巴嫩初潮后青春期女孩参与了本研究（22名超重[BMI>25 kg/m²]青春期女孩[15.4±2.4岁]和20名成熟度匹配[15.2±1.9岁]的对照组[BMI<25 kg/m²]）。采用双能X线吸收法（DXA）测量身体成分和骨矿物质密度（BMD）。完成了FN和L2-L4的BMAD计算。与正常体重女孩相比，超重女孩的FN和L2-L4的BMAD值更高（p<0.01）。在整个人口中，脂肪量是L2-L4和FN的BMAD的正向决定因素（分别为p<0.001和p<0.05）。
在该研究组中，超重与较高的L2-L4和股骨颈BMAD值相关。
