  • 摘要:
      目的   了解四川省西昌市吸毒人群首次海洛因滥用的发生情况。
      方法   于2004年5~7月, 从社区中搜集吸毒人群, 调查其社会人口学特征、首次使用毒品的时间和方式及种类、首次吸毒前吸烟、饮酒、朋友、家庭成员和亲戚吸毒的情况。
      结果   在调查的451名吸毒人员中, 首次使用的毒品均为海洛因, 其中, 首次吸毒方式为口吸和静脉注射的分别为80.7%和19.3%。从出生到首次吸毒的发生率为4.43/100人年(95%CI=4.02~4.84)。多因素Cox比例风险模型分析结果显示, 彝族及其他少数民族(HR=1.47, 95%CI=1.22~1.78)、15岁以前开始吸烟(HR=1.54, 95%CI=1.25~1.83)与首次吸毒发生的关系差异有统计学意义。
      结论   需进一步了解吸毒人群首次吸毒的发生情况及其影响因素, 为开展针对性的健康教育和行为干预措施提供科学指导。
