从2002年到2017年，美国产前使用大麻的流行率几乎翻了一番。随着大麻合法化的不断扩大，这项研究旨在评估美国孕妇中大麻使用率、大麻依赖和大麻风险认知的最新趋势。方法全国毒品使用与健康调查(2002-2019年)旨在代表美国平民非制度化人口。研究样本包括怀孕参与者(年龄12-44岁；n=15,109)。大麻消费的定义是在评估前30天内至少使用一次大麻。过去12个月的大麻依赖是根据DSM-IV定义的。在控制年龄、种族/民族和家庭收入的同时，使用连接点回归来检验这些趋势的显著变化。分析在2021年8月至2022年4月期间进行。结果在2016年至2017年(5.8%)至2018年至2019年(4.7%)期间，未发现产前大麻使用率发生变化的证据(流行率差异=−1.1；95%CI=−2.9、0.7)。从2002年到2019年，孕妇中大麻依赖的流行率没有明显变化。从2002年到2007年，认为经常使用大麻(1-2次/周)的孕妇比例保持稳定(∼为53%)，之后急剧下降(27%)。结论美国4名孕妇中有3人不认为经常使用大麻是非常危险的。随着大麻合法化程度的提高，需要作出公共卫生努力，提高人们对使用大麻可能造成的危害的认识。
IntroductionThe prevalence of prenatal cannabis use has nearly doubled in the U.S. from 2002 to 2017. As cannabis legalization continues to expand, this study aimed to estimate the recent trends in the prevalence of cannabis use, cannabis dependence, and cannabis risk perceptions among U.S. pregnant people.MethodsThe National Survey on Drug Use and Health (2002–2019) was designed to be representative of the U.S. civilian non-institutionalized population. The study sample included pregnant participants (aged 12–44 years; n=15,109).Cannabis consumptionwas defined as using cannabis at least once in the 30 days before assessment.Past 12‒month cannabis dependencewas defined on the basis of the DSM-IV. Joinpoint regression was used to test for significant changes in the trends while controlling for age, race/ethnicity, and family income. Analyses were conducted between August 2021 and April 2022.ResultsNo evidence of change in the prevalence of prenatal cannabis use was detected between 2016–2017 (5.8%) and 2018–2019 (4.7%) (prevalence difference= −1.1; 95% CI= −2.9, 0.7). The prevalence of cannabis dependence did not change significantly among pregnant people from 2002 to 2019. The percentage of pregnant people perceiving regular cannabis use (1–2 times/week) as a great risk remained stable from 2002 to 2007 (∼53%) and declined sharply after (27%).ConclusionsThree of 4 pregnant people in the U.S. do not characterize regular cannabis use as a great risk. As cannabis legalization increases, public health efforts are needed to raise awareness of the possible harms associated with cannabis use.
