Low back pain and associated disability in Swedish adolescents

INTRODUCTION: Low back pain (LBP) defined as ache or pain in the lowest part of the back is a common experience among people all over the world. The lifetime prevalence is reported to be as high as 84%, and the prevalence of LBP seems to be almost the same among adolescents as among adults. The risk for having LBP later in life if you experienced LBP in adolescence is high. MATERIAL AND METHODS: In this cross‐sectional study of 2550 students aged 16‐20 years, we used the Standardized Nordic Questionnaire for the analysis of musculo‐skeletal symptoms. We studied gender difference, prevalence, and disability of Low back pain. We also studied differences in LBP in adolescent athletes depending on hours spent on sports or physical activity. RESULTS: Significantly, more girls than boys had had problems sometimes during their life. Those who participated in sports reported LBP to a significantly higher extent than those who were physically inactive in their spare time. Gender and spare time sports were important risk factors for getting LBP some time in life. There was a higher risk for girls to have low back pain problems more than 30 days or daily the last year if they had had low back pain some time earlier in life. CONCLUSION: This study shows that low back pain (LBP) is common among Swedish adolescents, more common among girls than boys. High sport activity was associated with the risk of having LBP, length of time with LBP, and disability due to LBP.
