组和健康组?采用双能X线骨密度仪(dualenergyX ̄rayabsorptiometry?DXA)测量骨密度(bonemassdensity?BMD)指标(股骨颈、全髋及腰椎BMD)?DXA自带分析软件计算股骨强度指数(femurstrengthindex?FSI)、截面指数(sectionmodulus?SM)、横截面面积(cross ̄sectionalarea?CSA)及曲线比率(bucklingratio?BR)?同时检测骨转换指标[I型前胶原氨基端肽(totalprocollagenType1aminoterminalpropeptide?P1NP)、β胶联降解产物(β-CrossLaps?β-CTX)]?结合3年随访观察两组OPF发生情况?结果:DXA测量显示:T2DM组股骨颈(L1~L4)BMD、全髋BMD、腰椎BMD和股骨近端FSI、SM、CSA明显低于健康组?BR显著高于健康组?差异均有统计学意义(t依次=2.332、2.367、2.314、5.612、5.007、9.835、2.821?P<0.05或<0.01)?骨转换检测显示:两组β ̄CTX水平相较?差异无统计学意义(P>0.05)?T2DM组P1NP水平较健康组低[(43.76±18.29)ng/mLvs.(53??84±20.16)ng/mL]?差异有统计学意义(t=2.716?P<0.01)?3年随访显示:T2DM组OPF发生率为16.42%?高于健康组的2.78%?差异有统计学意义(χ2=4.233?P<0.05)?T2DM组骨折发生于髋部、脊椎处和桡尺骨远端处?结论:T2DM可能通过降低老年绝经后女性BMD和骨强度及抑制骨生成转换等途径?增加OPF发生风险?应积极采取相关措施预防OPF发生?
