Relationship of Body Mass Index with Incident of Low Back Pain in Medical Student

Abstract

Currently Low Back Pain (LBP) is a major global health problem with an annual prevalence
of 22% - 65%. Many things are the cause of LBP such as spinal deformities from birth,
trauma, age, pregnancy and body mass index (BMI). Several previous research are still
controversial whether the relationship of body mass index with incidence of low back pain.
The design of this study was cross sectional descriptive analytical with the aim to see the
relationship between body mass index and the incidence of low back pain in medical
students. This research was carried out at Ukrida Medical Faculty with a sample of 216
people with 64.4% respondents were female and men 35.6%, and respondent who
experienced mild low back pain were 94.9%, moderate at 5.1%. Based on body mass index,
the majority of respondents had a normal BMI of 55.6%, underweight of 6.9%, then overweight of 37.5% and those who experienced mild pain based on visual analogue scale of
79.6%, no pain at 10.2%, moderate pain 8.8%, then controlled severe pain is 1.4%. After
statistical tests using Pearson Chi-Square obtained results there is a relationship between
body mass index and the incidence of low back pain with p = 0.043.
