Castro-Piñero J, et al. - In this cross-sectional study, the physicians wished to explore the efficacy of neck circumference (NC) as a predictor of cardiovascular disease (CVD) and examine its association with numerous anthropometric and body composition indices as well as to release sex and age-specific NC cut-off values to classify youths as overweight/obese. They concluded that NC was a simple, low-cost and practical screening tool for the assessment of upper body obesity and CVD risk factors in children and adolescents. It could be used as a screening tool for overweight/obesity in a pediatric clinic. They also provided sex and age-specific thresholds to classify children and adolescents as normal weight or overweight/obese.
