The aim of this study was to explore the relation between birth weight and bone mass in a group of adolescent girls. This study included 40 post-menarchal adolescent (aged 13-20 years) girls. Anthropometric characteristics (height and weight) were measured and birth weights were obtained from the obstetric records. Body composition, bone mineral content (BMC) and bone mineral density (BMD) of the whole body (WB) were assessed by dual-energy X-ray absorptiometry (DXA). Calculations of the ratio BMC/height and of the bone mineral apparent density (BMAD) were completed for the WB. Birth weight was positively correlated to BMC and to the ratio BMC/height even after adjusting for weight and maturation index (years since menarche). Finally, birth weight was correlated to BMD even after adjusting for weight. In conclusion, this study suggests that birth weight is an independent determinant of whole body BMC and BMD in adolescent girls.
本研究旨在探讨一组青春期少女的出生体重与骨量之间的关系。该研究纳入了 40 名月经初潮后的青春期少女（年龄 13-20 岁）。测量了人体测量学特征（身高和体重），并从产科记录中获得了出生体重。通过双能 X 射线吸收法（DXA）评估了全身（WB）的身体成分、骨矿物质含量（BMC）和骨矿物质密度（BMD）。计算了 WB 的 BMC/身高比值和骨矿物质表观密度（BMAD）。即使在校正体重和成熟指数（初潮后年数）后，出生体重与 BMC 以及 BMC/身高比值仍呈正相关。最后，即使在校正体重后，出生体重仍与 BMD 相关。总之，本研究表明，出生体重是青春期少女全身 BMC 和 BMD 的独立决定因素。
