Is waist circumference a better and more practical index for identifying obesity-related cardiovascular disease risk compared to BMI in individuals with spinal cord injury?
Waist circumference ≥94 cm is a highly sensitive, practical alternative to BMI for predicting adverse cardiovascular disease risk profiles in individuals with spinal cord injury.
Obesity is an important identifier of cardiovascular disease (CVD) risk, but is challenging to determine accurately in individuals with spinal cord injury (SCI). Body mass index (BMI) is used worldwide as a simple indicator of obesity, but is difficult to measure in individuals with SCI. Furthermore, standard BMI cutoffs underestimate obesity in this population. Therefore, we aimed to identify the best marker of obesity in individuals with SCI, considering both practicality, and ability to detect adiposity and CVD risk. Five anthropometric measures were evaluated: BMI; waist circumference (WC); waist-to-height ratio (WHtR); waist-to-hip ratio; and neck circumference. We evaluated relationships between these measures and abdominal and total body-fat percentage, seven cardiovascular metabolic risk factors (fasting insulin, glucose, glucose tolerance, triglycerides, high-density lipoprotein, low-density lipoprotein, and total cholesterol), and the Framingham risk score. BMI, WC, and WHtR were correlated with abdominal fat percentage. WC and WHtR were correlated with five metabolic risk factors as well as the Framingham risk score. WC is a more practical measure for an SCI population. The optimal cutoff for identifying adverse CVD risk in individuals with SCI was identified as WC ≥94 cm, with 100% sensitivity and 79% specificity. We propose that WC is a simple, more sensitive alternative to BMI in this population that is easy to use in multiple settings. The cutoff provides a simple tool to predict adverse CVD risk profiles that can be used to guide risk management, as well as as a practical aid for individuals with SCI to maintain a healthy body composition.
Ravensbergen et al. (Thu,) conducted a cross-sectional in Spinal cord injury. Waist circumference vs. Body mass index and other anthropometric measures was evaluated on Adverse cardiovascular disease risk. Waist circumference ≥94 cm was the optimal cutoff for identifying adverse cardiovascular disease risk in individuals with spinal cord injury, demonstrating 100% sensitivity and 79% specificity.
