Burnout syndrome (BS) is highly prevalent among medical students and is associated with lower empathy and worsening of medical students ́ mental health. The aim of our study was to identify prevalence of BS during internship and its association with self-rated social support and participation in extracurricular activities in one medical school in Brazil. This was a cross-sectional study conducted in 2015, with 121 medical students on internship (56% response rate). They were evaluated using the Maslach Burnout Inventory – Human Services (MBI) and assessed about socio demographic data, social support and extracurricular activities. The overall BS prevalence was 57.5% among medical interns. High emotional exhaustion was present in 33.1% (N = 38) of interns, high depersonalization was observed in 45.7% (N = 58) and 36.2% of participants (N = 46) had low personal accomplishment. Individuals with participation in community services had lower frequency of depersonalization (prevalence ratio 0.61 CI95% 0.42–0.88). BS was not associated with different types of extracurricular activities and no association was found among BS and the behaviour of seeking social support. We found high prevalence of BS in medical interns, however the behaviour of seeking social support had no association with BS. The interns participating in community activities had lower frequency of high depersonalization.

巴西实习医学生的倦怠综合征，课外活动和社会支持：横断面分析

倦怠综合症（BS）在医学生中非常普遍，并且与较低的同理心和医学生的心理健康状况恶化相关。我们研究的目的是确定在实习期间BS的患病率及其与自我评价的社会支持和参与巴西一所医学院校课外活动的关系。这是2015年进行的一项横断面研究，共有121名医学生在实习（回复率56％）。他们使用Maslach倦怠量表-人类服务（MBI）进行了评估，并对社会人口统计学数据，社会支持和课外活动进行了评估。在医学实习生中，整体BS患病率为57.5％。33.1％（N = 38）的实习生情绪高度疲惫，45.7％（N = 58）和36的人格化程度很高。2％的参与者（N = 46）的个人成就感很低。参与社区服务的人的去个性化频率较低（患病率0.61 CI95％0.42-0.88）。BS与不同类型的课外活动无关，并且在BS与寻求社会支持的行为之间未发现关联。我们发现医学实习生中BS的患病率很高，但是寻求社会支持的行为与BS没有关联。参加社区活动的实习生高人格化的频率较低。BS与不同类型的课外活动无关，并且在BS与寻求社会支持的行为之间未发现关联。我们发现医学实习生中BS的患病率很高，但是寻求社会支持的行为与BS没有关联。参加社区活动的实习生去人格化的频率较低。BS与不同类型的课外活动无关，并且在BS与寻求社会支持的行为之间未发现关联。我们发现医学实习生中BS的患病率很高，但是寻求社会支持的行为与BS没有关联。参加社区活动的实习生高人格化的频率较低。
