Low back pain (LBP) is a common problem in the general population. Medical students may be at risk of LBP because of demanding curricula. To study the prevalence of LBP in Brazilian medical students and the associated factors. Six hundred twenty-nine medical students (72.8% females, mean age of 23 years old) answered a questionnaire containing epidemiological data; data on presence and frequency of LBP, use of painkillers, and LBP interference in daily activities; number of sitting and exercising hours/day, posture habits. They also filled a VAS (or visual analogic scale) on the own perception of anxiety, depression, fatigue, and the Roland Morris functional questionnaire for LBP. In this sample, 81.7% had periods of recurrent LBP that was more common in females (77.6% vs 51.3%; p < 0.0001) and associated with bad posture habits (p < 0.0001). Number of sitting hours, exercising, and study period at school could not be associated with LBP. The mean Roland Morris result was 4.0; IQR = 2-7 and its value showed a modest correlation with VAS of anxiety (rho = 0.21) and depression (rho = 0.33). LBP interfered with social activities in 20.5%, with physical activities in 33.1%, and in school activities in 29.2%. There is a high prevalence of LBP in medical students, mainly females, associated with bad posture habits. Physical dysfunction for LBP showed correlation with anxiety and depression.
下腰痛（LBP）在普通人群中很常见。由于课程要求苛刻，医学生可能有患 LBP 的风险。研究巴西医学生 LBP 的患病率及相关因素。629 名医学生（72.8%为女性，平均年龄 23 岁）回答了一份包含流行病学数据的问卷；存在和 LBP 的频率、止痛药的使用以及 LBP 对日常活动的干扰；每天坐着和锻炼的时间/小时、姿势习惯的数据。他们还使用视觉模拟量表（VAS）评估自己的焦虑、抑郁、疲劳感，以及 Roland Morris 下腰痛功能问卷。在这个样本中，81.7%有反复发作的 LBP，女性更为常见（77.6%比 51.3%；p<0.0001），与不良姿势习惯有关（p<0.0001）。坐着的时间、锻炼和在校学习时间与 LBP 无关。Roland Morris 的平均得分为 4.0；IQR=2-7，其值与焦虑的 VAS （rho=0.21）和抑郁的 VAS （rho=0.33）呈中度相关。20.5%的人 LBP 干扰社交活动，33.1%干扰体育活动，29.2%干扰学校活动。医学生 LBP 患病率较高，主要为女性，与不良姿势习惯有关。LBP 的躯体功能障碍与焦虑和抑郁有关。
