High-risk injection drug use and its accompanying sexual behaviors have large social and financial costs. However, little is known about how age and age at first drug use are related to high-risk injection or sex behaviors. The current study draws on life course perspectives and data from the NIDA Cooperative Agreement to examine the relationship between eight high-risk behavior variables and age and age at first drug use. Random effects negative binomial regression models reveal that the frequency of high-risk sexual behaviors in the past month decreases up to 28% with each decade of age, although the frequency of high-risk injection behaviors in the past month increases by up to 62% with each decade of age. Both high-risk injection and high-risk sex behaviors are lower among those who initiated first drug use at later ages. Previous research has indicated the importance of interventions to reduce the high-risk sexual behaviors of older drug users. The current study suggests a refocusing of public health efforts on their high-risk injection habits.
高危注射毒品使用及其伴随的性行为会带来巨大的社会和经济成本。然而，人们对年龄和首次吸毒年龄与高危注射或性行为之间的关系知之甚少。本研究借鉴生命历程的观点和 NIDA 合作协议的数据，考察了八种高危行为变量与年龄和首次吸毒年龄之间的关系。随机效应负二项回归模型显示，过去一个月高危性行为的频率每增加十年就会降低 28%，尽管过去一个月高危注射行为的频率每增加十年就会增加 62%。首次吸毒年龄较大的人，高危注射和高危性行为的发生频率都较低。先前的研究表明，干预措施对于减少老年吸毒者的高危性行为非常重要。本研究表明，公共卫生工作的重点应该重新放在他们的高危注射习惯上。
