Cannabis use has significant negative consequences for youth. Depression is associated with greater cannabis use among adults but less is known about cannabis use and depression among youth. This study investigated whether depression is associated with increased cannabis use among youth in the United States (US), overall and by demographics, and examined trends in cannabis use by depression status among youth from 2004 to 2016.
Data were from the 2004-2016 National Survey on Drug Use and Health (NSDUH), annual cross-sectional national samples of US persons 12 and older. The analytic sample included respondents aged 12-17 (total combined n=204,102). First, the prevalence of past-month cannabis use by past-year depression status among youth was examined, overall and by demographic subgroups, using pooled data from 2004-2016. Next, linear time trends of past-month cannabis use were assessed by depression status from 2004 to 2016 using logistic regression models with continuous year as the predictor. Models with year-by-depression status interaction terms assessed differential time trends for those with and without depression.
From 2004-2016, cannabis use increased both among youth with and without depression. Cannabis use increased significantly more rapidly among youth with (8.45% to 11.65%), compared to without, depression (4.28% to 4.71%). Youth with depression were more than twice as likely to report cannabis use (12.86% versus 6.40%), relative to those without depression.
Cannabis use was more than twice as common and increased more rapidly from 2004 to 2016 among youth with depression compared to youth without depression.
大麻的使用对青少年有显著的负面影响。成年人中，抑郁与大麻使用量增加有关，但青少年中关于大麻使用和抑郁的关联研究较少。本研究旨在调查抑郁是否与美国青少年中大麻使用量增加有关，包括整体情况以及按人口统计学因素的情况，并研究 2004 年至 2016 年间抑郁青少年的大麻使用趋势。
数据来自 2004-2016 年全国毒品使用与健康调查（NSDUH），这是一项对美国 12 岁及以上人群进行的年度横断面全国性抽样调查。分析样本包括年龄在 12-17 岁的受访者（总共有 204102 人）。首先，在 2004-2016 年的综合数据中，检查了青少年中过去一年有抑郁症状者的过去一个月大麻使用的流行率，包括总体情况和按人口统计学亚组情况。其次，使用 logistic 回归模型，以连续年份为预测因子，评估 2004 年至 2016 年期间抑郁状态下过去一个月大麻使用的线性时间趋势。对于有抑郁和无抑郁的个体，通过在模型中加入年份与抑郁状态的交互项来评估不同的时间趋势。
2004-2016 年，有抑郁和无抑郁的青少年的大麻使用都有所增加。与无抑郁的青少年相比，有抑郁的青少年的大麻使用增加速度更快（从 8.45%到 11.65%）。有抑郁的青少年报告大麻使用的可能性是无抑郁的青少年的两倍多（12.86%对 6.40%）。
与无抑郁的青少年相比，有抑郁的青少年的大麻使用更为普遍，而且从 2004 年到 2016 年，其使用速度增加得更快。
