Objective: To determine the frequency of low back pain in undergraduate students of Khyber Medical University (KMU).
Methodology: It was a cross-sectional study conducted at Khyber Medical University, Peshawar, Pakistan. The study was conducted between September, 2014 and February, 2015. Undergraduate medical students aged between 17 to 25 years participated in the study. A total of 292 students participated in the study. The undergraduate medical students of KMU institutes were included in the study while excluding students having LBP due to systemic diseases, post-surgical and neoplasm.

LBP in male students was 47.7% while in female was about 56.7 %. About 40.8% students reported mild pain on VAS. The risk factors contributing to LBP were lack of exercise, abnormal posture during study and wards’ hours, lack of chair with lumber support.
