The purpose of this study was to examine factors associated with heroin use during methadone maintenance treatment.
Logistic regression statistical models were used to examine data obtained in a cross-sectional sample of 652 methadone patients.
Heroin use during the 3 months prior to interview was shown to be greatest among (1) patients maintained on methadone dosages of less than 70 mg/day (adjusted odds ratio [OR] = 2.1, 95% confidence interval [CI] = 1.3, 3.4) and (2) patients who used cocaine during treatment (adjusted OR = 5.9, 95% CI = 3.8, 9.1). These results were independent of treatment duration, treatment compliance, alcohol use, and socioeconomic factors. Cocaine users were more likely than nonusers of cocaine to use heroin at all methadone dosage levels.
This study confirms and extends past research showing high-dose methadone maintenance to be important to heroin abstinence. Further investigation of the independent association between heroin use and cocaine use is needed.
本研究旨在探讨美沙酮维持治疗期间与海洛因使用相关的因素。
采用逻辑回归统计模型分析从652名美沙酮治疗患者的横断面样本中获取的数据。
在接受访谈前3个月内使用过海洛因的患者中,(1)接受每日剂量低于70毫克美沙酮维持治疗的患者(校正比值比[OR]=2.1,95%置信区间[CI]=1.3,3.4)以及(2)治疗期间使用过可卡因的患者(校正OR=5.9,95%CI=3.8,9.1)使用海洛因的情况最为严重。这些结果不受治疗时长、治疗依从性、酒精使用情况及社会经济因素的影响。在所有美沙酮剂量水平下,可卡因使用者比未使用可卡因者更有可能使用海洛因。
本研究证实并拓展了以往的研究,表明高剂量美沙酮维持治疗对戒除海洛因至关重要。有必要进一步研究海洛因使用与可卡因使用之间的独立关联。
