We analyzed data for San Francisco intravenous drug users entering treatment, April 1986-September 1988 (N = 7,660). The proportion of cases reporting any needle sharing in the month preceding treatment decreased from 50 percent in 1986 to 28 percent in 1988. Similar decreases were reported by two longitudinal cohorts (needle sharing by the same individuals) admitted in 1986 and 1987 (n = 303), and in 1986 and 1988 (n = 205). In a multiple logistic regression model four variables predicted needle sharing: earlier time of admission, cocaine use, younger age, and being White rather than Black.
我们分析了1986年4月至1988年9月期间进入治疗的旧金山静脉注射吸毒者的数据(N = 7660)。报告在治疗前一个月有任何共用针头情况的病例比例从1986年的50%降至1988年的28%。1986年和1987年收治的两个纵向队列(同一批人的共用针头情况)(n = 303)以及1986年和1988年收治的队列(n = 205)也报告了类似的下降情况。在一个多元逻辑回归模型中,有四个变量可预测共用针头情况:入院时间较早、使用可卡因、年龄较小以及是白人而非黑人。
