摘要(Abstract)：
目的了解四川省凉山彝族自治州西昌市静脉吸毒人群死亡率及死因情况。方法于2002年11月招募静脉吸毒人群前瞻性研究队列376人,调查其社会人口学、吸毒行为和性行为特征。计算静脉吸毒人群3年随访的死亡率和死因构成,对其影响因素采用单因素和多因素Cox回归模型分析。结果在队列3年随访中,死亡44人,死亡率为42.60/1 000人年(95%CI:30.02~55.19),标准化死亡比为27.35(95%CI:15.66~46.24)。吸毒过量占全部死因的68.2%(30/44)。多因素Cox回归模型分析未见与全死因有统计学意义的变量,但见吸毒年限≥10年(RR值,3.04;95%CI:1.42~6.50;P=0.004 1)和近3个月静脉注射频率≥7次/周(RR值,2.70;95%CI:1.24~5.89;P=0.012 7)与吸毒过量死亡差异有统计学意义。结论吸毒过量是西昌市静脉吸毒人群的主要死因,需进一步探讨吸毒过量死亡的影响因素及其干预对策。
