Popis: 目的 探讨总胆固醇负荷(TC负荷)与新发外周动脉疾病(peripheral artery disease,PAD)的关系。 方法 在开滦队列研究的子队列即无症状性多血管异常社区研究中,2006—2012年每2年对参与者进行随访,每次随访时进行TC测定,TC负荷定义为测量值和临界值之差的加权和。在第3次和第4次随访时完成踝臂指数(ankle-brachial index,ABI)测量,单侧或双侧下肢ABI<0.90认为存在PAD。根据TC负荷四分位数将参与者分为4组,并通过logistic回归评估TC负荷与PAD之间的关系。 结果 本研究共纳入2939例参与者,其中159例(5.4%)合并新发PAD。在单因素分析中,与最低四分位数(Q1)组相比,TC负荷升高与新发PAD无相关(OR 1.109,95%CI 0.961~1.280,P=0.157),且校正混杂因素后TC负荷与新发PAD仍无相关(OR 1.062,95%CI 0.916~1.232,P=0.346)。在4组参与者中,第2四分位数(Q2)组的参与者新发PAD的发生率最低,与Q2组相比,Q1组及最高四分位数(Q4)组整体参与者新发PAD风险升高(剔除年龄≥65岁的参与者后Q4组差异无统计学意义),而与第3四分位数(Q3)组参与者的差异不具有统计学意义。 结论 TC负荷与新发PAD不存在显著的线性相关性,但长期TC水平过高或过低可能会增加新发PAD风险。 Objective To investigate the relationship between TC burden and newly developed peripheral artery disease (PAD) . Methods In the asymptomatic polyvascular abnormalities community (APAC) study, the participants (were followed-up every 2 years from 2006 to 2012. The TC was measured at each follow-up. TC burden was calculated as the weighted sum of the difference between measured value and cutoff value. Ankle-brachial index (ABI) measurements were completed at the third and fourth follow-up, and unilateral or bilateral lower extremity ABI
