EVALUATION OF LOW BACK PAIN IN PATIENTS WHO UNDERWENT BARIATRIC SURGERY

ABSTRACT Objective Low back pain is an extremely common condition that can affect up to 84% of people at some point in life. It affects patients of both sexes, mainly between 30 and 50 years of age, and has a great impact on the quality of life, in addition to placing a significant demand on health services. Obesity is considered as an important risk factor for the development of low back pain since the change in body fat distribution causes changes in the locomotor system and especially in the spine. Methods The study makes a comparative, retrospective analysis of patients who underwent bariatric surgery through questionnaires to assess the improvement in their quality of life and low back pain. The data were submitted to a statistical analysis and the results compared to the literature data. Results As a result, there was a statistically significant improvement in quality of life in relation to weight loss; the greater the weight reduction, the better the quality of life and the younger the patient, the better their quality of life. Conclusions When asked about low back pain, 70.7% of patients classified it as moderate to severe. Level of evidence III; Comparative retrospective.

摘要 目的 下腰痛（Low Back Pain）是一种极为常见的病症，人群终身患病率可达84%。该病症可累及男女两性，高发年龄段为30至50岁，不仅严重降低患者的生活质量，还对医疗卫生系统造成了沉重的服务负担。肥胖被认为是诱发下腰痛的重要危险因素，体脂分布的改变会引发运动系统尤其是脊柱的结构与功能变化。
方法 本研究针对接受减重手术（Bariatric Surgery）的患者开展回顾性对照分析，通过问卷调查评估其生活质量与下腰痛症状的改善情况。对收集到的数据进行统计学分析，并将本研究结果与已发表文献数据进行对比。
结果 研究结果显示，体重减轻与患者生活质量的统计学意义显著改善相关；体重降幅越大，患者生活质量提升越显著，且患者年龄越小，其生活质量改善效果越好。
结论 当被问及下腰痛症状时，70.7%的患者将其病情评定为中度至重度。本研究证据等级为Ⅲ级，属于回顾性对照研究。
