Obesity is associated with chronic low back pain (CLBP), but the association between fat distribution and CLBP is unclear. This cross-sectional study evaluated the relationship using the Korean National Health and Nutrition Examination Survey data. A total of 10,606 adults (average age: 45.4, female: 57.1%) were included. We estimated the regional fat distribution, waist circumference, and body fat proportion, compared the values in people with and without CLBP, and stratified the estimates by sex and obesity status using a multivariable linear model. There were no statistically significant differences in the average waist circumference between the people with and without CLBP (p = 0.731) and the average fat proportion between those with and without CLBP (p = 0.731). The average regional fat distribution was significantly higher in the people with CLBP than in those without CLBP, in the upper limbs (11.4%, 95% confidence interval [CI]: [11.3, 11.5] vs. 11.2%, 95% CI: [11.1, 11.3], p < 0.05) and in the lower limbs (31.9%, 95% CI: [31.6, 32.2] vs. 31.4%, 95% CI: [31.2, 31.6], p < 0.01). More obvious among men, fat distribution in the lower limbs is higher than in people without obesity (p < 0.001). People with CLBP tend to have a higher fat distribution in the limbs than those without it and obese people with CLBP would need to reduce the fat in the lower limbs.
肥胖与慢性下背痛（CLBP）有关，但脂肪分布与 CLBP 的关系尚不清楚。本横断面研究使用韩国国家健康和营养检查调查数据评估了这种关系。共纳入 10606 名成年人（平均年龄：45.4 岁，女性：57.1%）。我们估计了区域脂肪分布、腰围和体脂比例，比较了 CLBP 患者和无 CLBP 患者的这些值，并使用多变量线性模型按性别和肥胖状况对估计值进行分层。CLBP 患者和无 CLBP 患者的平均腰围（p = 0.731）和无 CLBP 患者的平均脂肪比例（p = 0.731）无统计学差异。CLBP 患者的上肢（11.4%，95%置信区间[CI]：[11.3，11.5] vs. 11.2%，95%CI：[11.1，11.3]）和下肢（31.9%，95%CI：[31.6，32.2] vs. 31.4%，95%CI：[31.2，31.6]）的平均区域脂肪分布明显高于无 CLBP 患者（均<0.05）。在男性中更为明显，下肢脂肪分布高于无肥胖者（p<0.001）。CLBP 患者下肢脂肪分布高于无 CLBP 患者，肥胖 CLBP 患者需要减少下肢脂肪。
