The presented percentile distributions of waist circumference for school children and adolescents in Łódź should be used together with the general assessment of a child's obesity, e.g. while applying local percentile distributions of the BMI index. The knowledge of both indices (BMI and WC) enhances the evaluation of potential risk for excessive adiposity in which the centrally located adipose tissue plays a significant role. The LMS method used for construction of percentile distributions provides optimal adjustment and smoothing of curves also enabling easy transformation of individual WC values in cm into their percentile representation. A critical WC value for an examined child equal to or exceeding half of its body height can be considered a simplified criterion similar for both sexes distinguishing abdominal obesity.
