Minority groups generally experience more disparities than whites in behavioral healthcare use. The population of racial/ethnic groups is growing faster than whites. Given increased concerns of cannabis use (CU) and its associations with health conditions, we examined national trends in cannabis use disorder (CUD) among adults aged ≥18 by race/ethnicity.
Data were from the 2005-2013 National Surveys on Drug Use and Health (N=340,456). We compared CU patterns and the conditional prevalence of CUD among cannabis users by race/ethnicity to understand racial/ethnic variations in CUD.
Approximately 1.5% of adults met criteria for a CUD in the past year. Regardless of survey year, cannabis dependence was more common than cannabis abuse, representing 66% of adults with a CUD. Across racial/ethnic groups, the prevalence of cannabis abuse and dependence remained stable during 2005-2013. In the total adult sample, the odds of weekly CU, monthly CU, and cannabis dependence were greater among blacks, native-Americans, and mixed-race adults than whites. Among cannabis users, the odds of cannabis abuse and dependence were greater among blacks, native-Americans, and Hispanics than whites. Logistic regression controlling for age, sex, education, and survey year indicated an increased trend in monthly CU and weekly CU in the total sample and among past-year cannabis users. Younger age, male sex, and low education were associated with increased odds of cannabis dependence.
The large sample provides robust information that indicates a need for research to monitor CUD and identify culturally appropriate interventions especially for targeting minority populations.
在行为健康护理的使用方面，少数群体通常比白人面临更多的差异。种族/族裔群体的人口增长速度比白人更快。鉴于对大麻使用（CU）及其与健康状况关联的担忧日益增加，我们研究了18岁及以上成年人中按种族/族裔划分的大麻使用障碍（CUD）的全国趋势。
数据来自2005 - 2013年全国药物使用和健康调查（N = 340,456）。我们比较了按种族/族裔划分的大麻使用模式以及大麻使用者中CUD的条件患病率，以了解CUD中的种族/族裔差异。
在过去一年中，约1.5%的成年人符合CUD标准。无论调查年份如何，大麻依赖比大麻滥用更常见，占患有CUD成年人的66%。在2005 - 2013年期间，各种族/族裔群体中，大麻滥用和依赖的患病率保持稳定。在成年总样本中，黑人、美国原住民和混血成年人每周使用大麻、每月使用大麻以及大麻依赖的几率高于白人。在大麻使用者中，黑人、美国原住民和西班牙裔中大麻滥用和依赖的几率高于白人。控制年龄、性别、教育程度和调查年份的逻辑回归表明，总样本以及过去一年大麻使用者中每月使用大麻和每周使用大麻呈上升趋势。年龄较小、男性和低教育程度与大麻依赖几率增加有关。
大样本提供了有力信息，表明需要开展研究以监测CUD，并确定特别针对少数群体的文化上合适的干预措施。
