This population-based cross-sectional study analyzed electronic health record data of pregnant individuals in an integrated health care delivery system in California to examine changes in prenatal cannabis use through self-report and urine toxicology testing during standard prenatal care between 2012 (n=33,546) and 2022 (n=43,415), and to test whether trends differed by race and ethnicity or age. The prevalence of prenatal cannabis use increased from 5.5% (95% CI, 5.3-5.8%) in 2012 to 9.0% (95% CI, 8.7-9.2%) in 2022 (adjusted prevalence ratio [aPR] 1.82, 95% CI, 1.72-1.92), with similar increases by toxicology test (aPR 1.70, 95% CI, 1.60-1.81) and self-report (aPR 2.12, 95% CI, 1.95-2.30). The increase in prevalence varied significantly across racial and ethnic and age groups, with the highest prevalence among Black individuals and those aged 13-24 across years. Although rates increased more slowly among groups with the highest prevalence of use, disparities persisted over time.
这项基于人群的横断面研究分析了加利福尼亚州一个综合医疗服务系统中孕妇的电子健康记录数据，以检查在标准产前护理期间，通过自我报告和尿液毒理学检测，2012 年（n=33546）和 2022 年（n=43415）之间产前大麻使用的变化，并测试这些趋势是否因种族和民族或年龄而异。2012 年，产前大麻使用的流行率为 5.5%（95%CI，5.3-5.8%），到 2022 年上升至 9.0%（95%CI，8.7-9.2%）（调整后的流行率比[aPR]1.82，95%CI，1.72-1.92），通过毒理学检测（aPR 1.70，95%CI，1.60-1.81）和自我报告（aPR 2.12，95%CI，1.95-2.30）也有类似的增加。流行率的增加在不同种族和民族以及年龄组之间存在显著差异，黑人个体和 13-24 岁个体的流行率最高。尽管高使用率群体的增长率较慢，但随着时间的推移，差距仍然存在。
