Although there are a number of studies about substance use by medical students, the majority are still cross-sectional. We aimed to investigate prevalence, 2-year incidence, and factors associated with substance use during medical training.
This longitudinal study included medical students in 4 different waves (with each wave equaling 1 semester). Socio-demographic data, Duke Religion Index (DUREL), DASS-21, and the "Alcohol, Smoking and Substance Involvement Screening Test" (ASSIST) were used.
A total of 327 (56.2%) medical students were followed for 2 years. Prevalence of lifetime substance use was 89.9% for alcohol, 34.5% for cannabis, and 17.1% for sedatives. Tobacco had the greatest incidence of use over the 2 years (16.4%), followed by alcohol (13.8%) and cannabis (13.8%). At least 24% of the students would need an intervention for alcohol use, 11.4% for tobacco, and 6.5% for cannabis. Alcohol use during wave 4 was associated with organizational religiosity, and alcohol and tobacco use at the baseline; tobacco use during wave 4 was associated with age, non-organizational religiosity, and cannabis and tobacco use at the baseline; and cannabis use during wave 4 was associated with cannabis and tobacco use at the baseline.
Our results indicate an increase in the incidence of lifetime substance use during medical training. Prior use of substance was associated with a higher chance of use after 2 years, while age and religiousness seem to reduce the chance of use.
尽管有许多关于医学生物质使用的研究，但大多数仍为横断面研究。我们旨在调查医学培训期间物质使用的流行率、2 年发生率和相关因素。
本纵向研究纳入了 4 个不同波次（每个波次相当于 1 个学期）的医学生。采用了社会人口统计学数据、杜克宗教指数（DUREL）、DASS-21 和“酒精、吸烟和物质使用参与筛查测试”（ASSIST）。
共有 327 名（56.2%）医学生随访 2 年。终生物质使用的患病率为：酒精 89.9%，大麻 34.5%，镇静剂 17.1%。在 2 年内，烟草的使用率增长最高（16.4%），其次是酒精（13.8%）和大麻（13.8%）。至少 24%的学生需要干预酒精使用，11.4%需要干预烟草使用，6.5%需要干预大麻使用。第 4 波次的酒精使用与组织宗教信仰有关，与基线时的酒精和烟草使用有关；第 4 波次的烟草使用与年龄、非组织宗教信仰以及基线时的大麻和烟草使用有关；第 4 波次的大麻使用与基线时的大麻和烟草使用有关。
我们的研究结果表明，医学生在医学培训期间终生物质使用的发生率增加。既往物质使用与 2 年后物质使用的可能性增加有关，而年龄和宗教信仰似乎降低了物质使用的可能性。
