身体质量指数和椎旁肌磁共振质子密度脂肪分数在慢性腰痛患者复发中的临床价值
Clinical value of body mass index and paraspinal muscle MRI proton density fat fraction in recurrence in patients with chronic low back pain
摘要
Abstract
Objective:To investigate the relationship between body mass index(BMI)and lumbar paraspinal muscle imaging parameters with the recurrence of chronic low back pain(CLBP).Materials and Methods:The patients with CLBP were prospectively recruited from the First Affiliated Hospital of Kunming Medical University,Baoshan People's Hospital,Dali Bai Autonomous Prefecture People's Hospital and The first People's Hospital of Honghe State.Clinical and imaging data were collected.Patients were divided into non-overweight(18.5 to 23.9 kg/m²)and overweight(≥24.0 kg/m2)groups based on BMI,and differences in paraspinal muscle parameters between groups were analyzed.Univariate and multivariate analyses were used to identify risk factors for CLBP recurrence.Receiver operating characteristic(ROC)curves were employed to evaluate the predictive performance of different models and to compare model performance after incorporating paraspinal muscle parameters and BMI.Results:This study included a total of 317 patients with CLBP,consisting of 126 males(39.75%).Recurrence was observed in 116 patients(36.59%),and 110 patients(34.70%)were overweight.The multifidus muscle proton density fat fraction(MPDFF)was significantly higher in the recurrence group than in the non-recurrence group(P<0.05).At the L4-L5 level,the multifidus muscle cross sectional area(MCSA)was significantly smaller in the recurrence group compared to the non-recurrence group(P<0.05).Logistic regression analysis showed that elevated MPDFFL4-L5(P=0.008,OR=1.04)and MCSAL4-L5(P=0.037,OR=0.84)were independent predictors of CLBP recurrence.The area under the receiver operating characteristic curve(AUC)for the model combining lumbar paraspinal parameters with clinical characteristics was superior to that of BMI(0.64 vs.0.60,P<0.05).Conclusions:Lumbar paraspinal muscle PDFF is associated with CLBP recurrence and has a better predictive value than BMI.关键词
