背景：医用大麻使用的趋势和相关性对于告知正在进行的临床，研究，政策和计划工作非常重要。本研究评估了美国成年人使用医用大麻的趋势和相关性。方法：我们分析了大约147，200名18岁或以上的美国平民参加2013-2015年全国药物使用和健康调查的数据。描述性分析，多变量逻辑回归，和零截断本地二项回归应用。结果：在美国成年人中，医用大麻使用的流行率从2013年的1.2%增加到2015年的1.6%（p = 0.0007）。在调整协变量后，居住在医用大麻州的成年人（医用大麻使用合法化的州）2015年医用大麻使用的可能性是2013年的1.3倍（调整后的比值比（AOR）= 1.3，95%置信区间（CI）= 1.03-1.61），非医用大麻州的成年人在2015年报告医用大麻使用的可能性是2013年的1.4倍（AOR = 1.4，95% CI = 1.05-1.90）。在过去12个月内专门用于医疗目的的大麻使用者中，12个月大麻使用障碍的趋势，每日或接近每日使用，以及大麻使用的天数在2013-2015年期间保持不变。我们确定了医用大麻州的成年人使用医用大麻的相关性与非医用大麻州的成年人使用医用大麻的相关性有何不同。结论：2015年，在医用大麻州和非医用大麻州，成年人使用医用大麻的可能性都高于2013年。临床医生需要了解和解决患者使用医用大麻的演变模式。
Background: Trends in and correlates of medical marijuana use are important to inform ongoing clinical, research, policy, and programmatic efforts. This study assessed trends in and correlates of medical marijuana use among U.S. adults.Methods: We analyzed data from approximately 147,200 U.S. civilians aged 18 or older who participated in the 2013-2015 National Surveys on Drug Use and Health. Descriptive analyses, multivariable logistic regressions, and zero-truncated native binomial regressions were applied.Results: Among U.S. adults, the prevalence of medical marijuana use increased from 1.2% in 2013 to 1.6% in 2015 (p = 0.0007). After adjusting for covariates, adults residing in medical marijuana states (states with legalized medical marijuana use) were 1.3 times more likely to use marijuana medically in 2015 than in 2013 (adjusted odds ratio (AOR) = 1.3, 95% confidence interval (CI) = 1.03-1.61), and adults in nonmedical marijuana states were 1.4 times more likely to report medical marijuana use in 2015 than in 2013 (AOR = 1.4, 95% CI = 1.05-1.90). Among adults who used marijuana exclusively for medical purposes in the past 12 months, trends in 12-month cannabis use disorders, daily or near daily use, and the number of days of marijuana use remained unchanged during 2013-2015. We identified how correlates of medical marijuana use among adults in medical marijuana states differed from their counterparts in nonmedical marijuana states.Conclusions: Adults were more likely to use marijuana medically in 2015 than in 2013 in both medical and nonmedical marijuana states. Clinicians need to learn about and address evolving patterns of medical marijuana use in patients.
