目的调查1型糖尿病患者严重低血糖的发病率及其危险因素。方法自2010年8月6日至2012年3月31日在广东省16家医院收集1型糖尿病患者的人口学资料、病史等信息,中心化检测糖化血红蛋白(HbA1C)和固定餐后2 h C肽等;严重低血糖发病和复发的...目的调查1型糖尿病患者严重低血糖的发病率及其危险因素。方法自2010年8月6日至2012年3月31日在广东省16家医院收集1型糖尿病患者的人口学资料、病史等信息,中心化检测糖化血红蛋白(HbA1C)和固定餐后2 h C肽等;严重低血糖发病和复发的危险因素分别采用Poisson回归模型和logistic回归模型分析。结果共纳入611例1型糖尿病患者,严重低血糖发病率为70.6次/100人年,发病危险因素有男性(RR=1.69)、医保报销比例<50%(RR=1.38)、长病程(RR=1.23)、消瘦(RR=1.43)、未控制饮食(RR=2.05)、体育锻炼<150 min/周(RR=1.61)、合并神经病变(RR=2.00)、吸烟(RR=1.46)和低HbA1C(RR=1.47)。而超重和肥胖者发生严重低血糖的风险较低(RR=0.60)。81.1%的严重低血糖集中发生在16.2%有复发史的患者,复发的危险因素有男性(RR=2.03)、消瘦(RR=2.02)、未控制饮食(RR=3.11)、体育锻炼<150 min/周(RR=2.87)和低HbA1C(RR=1.73)。而超重和肥胖者的风险较低(RR=0.28)。结论广东省1型糖尿病患者严重低血糖发病率高,且易复发;与一些可纠正的危险因素相关。展开更多
