The prevalence of mental distress is common for medical students in China due to factors such as the long duration of schooling, stressful doctor-patient relationship, numerous patient population, and limited medical resources. However, previous studies have failed to provide a comprehensive prevalence of these mental disorders in this population. This meta-analysis aimed to estimate the prevalence of common mental disorders (CMDs), including depression, anxiety, and suicidal behaviors, among medical students in China.
We conducted a systematic search for empirical studies on the prevalence of depression, anxiety, suicide attempt, suicide ideation, and suicide plan in Chinese medical students published from January 2000 to December 2020. All data were collected pre-COVID-19. The prevalence and heterogeneity estimations were computed by using a random-effects model and univariate meta-regression analyses.
A total of 197 studies conducted in 23 provinces in China were included in the final meta-analysis. The prevalence data of depression, anxiety, suicide attempt, suicide ideation, and suicide plan were extracted from 129, 80, 21, 53, and 14 studies, respectively. The overall pooled crude prevalence for depression was 29% [38,309/132,343; 95% confidence interval (CI): 26%-32%]; anxiety, 18% (19,479/105,397; 95% CI: 15%-20%); suicide ideation, 13% (15,546/119,069; 95% CI: 11%-15%); suicide attempt, 3% (1,730/69,786; 95% CI: 1%-4%); and suicide plan, 4% (1,188/27,025; 95% CI: 3%-6%).
This meta-analysis demonstrated the high prevalence of CMDs among Chinese medical students. Further research is needed to identify targeted strategies to improve the mental health of this population.
由于学习时间长、医患关系紧张、患者人群多、医疗资源有限等因素，中国医学生中精神困扰的患病率较高。然而，先前的研究未能提供该人群中这些精神障碍的综合患病率。本荟萃分析旨在估计中国医学生常见精神障碍（CMD）的患病率，包括抑郁、焦虑和自杀行为。
我们对 2000 年 1 月至 2020 年 12 月期间发表的关于中国医学生抑郁、焦虑、自杀未遂、自杀意念和自杀计划患病率的实证研究进行了系统检索。所有数据均在 COVID-19 之前收集。采用随机效应模型和单变量荟萃回归分析计算患病率和异质性估计值。
共有来自中国 23 个省的 197 项研究纳入最终荟萃分析。从 129 项、80 项、21 项、53 项和 14 项研究中提取了抑郁、焦虑、自杀未遂、自杀意念和自杀计划的患病率数据。抑郁的总体汇总粗患病率为 29%[38，309/132343；95%置信区间（CI）：26%-32%]；焦虑，18%（19，479/105397；95%CI：15%-20%）；自杀意念，13%（15，546/119069；95%CI：11%-15%）；自杀未遂，3%（1，730/69786；95%CI：1%-4%）；自杀计划，4%（1，188/27025；95%CI：3%-6%）。
本荟萃分析表明，中国医学生中 CMD 的患病率较高。需要进一步研究以确定针对该人群改善心理健康的目标策略。
