Abstract
Background
The weight-adjusted waist index (WWI) is a novel obesity index that is calculated as the waist circumference (WC) divided by the square root of body weight (kg). Previous studies have revealed that higher body mass index (BMI) and WC increase the risk of low back pain (LBP). However, no research explores the relationship between WWI and LBP.
Methods
Data utilized in this cross-sectional study were drawn from the National Health and Nutrition Examination Survey. Three logistic regression models were used to evaluate the association between WWI and LBP. Stratified analysis was applied to assess the stability of the results. Receiver-operating characteristic (ROC) curves were employed to visually assess and compare the predictive effectiveness of WWI, BMI, WC, and weight on LBP.
Results
A significant positive correlation was observed between WWI and LBP, model 1 (odds ratio [OR] = 1.222, 95% confidence interval (95% CI) [1.164, 1.283], P < 0.0001), model 2 (OR = 1.187, 95% CI [1.118, 1.261], P < 0.0001), and model 3 (OR = 1.129, 95% CI [1.056, 1.207], P < 0.001). Relative to the Q1, Q3 (model 1 (OR = 1.241, 95% CI [1.114, 1.382], P < 0.001), model 2 (OR = 1.192, 95% CI [1.050, 1.353], P = 0.007), model 3 (OR = 1.145, 95% CI [1.002, 1.310], P = 0.047)) and Q4 (model 1 (OR = 1.524, 95% CI [1.341, 1.733], P < 0.0001), model 2 (OR = 1.422, 95% CI [1.233, 1.640], P < 0.0001), model 3 (OR = 1.333, 95% CI [1.149, 1.547], P < 0.001)) all showed a significant positive correlation between them. The area under the receiver-operating characteristic curve (AUC) for WWI is 0.5447536, the AUC for BMI is 0.5466724, and the AUC for WC and weight is 0.5501341 and 0.5376615, respectively.
Conclusions
This cross-sectional study revealed a significant positive association between WWI and LBP, but WWI did not show better predictive efficacy than BMI and WC.
期刊介绍:
World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The journal''s mission is to:
-To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care.
-To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide.
-To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients.
Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
