Brazilian researchers interviewed 629 medical school students and found that 77% of female students and 51% of male students experienced periods of recurrent back pain. One in five said their back pain interfered with social activities, while about 30% noted back pain interfered with either physical activities or school activities. The research team also noted a strong association between the risk of recurrent back pain and poor posture habits among the participants in the study.
