Previously published weight estimation methods were included only if they used variables available from the NHANES data set. These are summarized in Table 1. The simplest and most accurate of Lorenz's formulae was used. 2 Both the Mercy and PAWPER XL‐MAC (PXM) methods were used virtually, with tables of data for the relevant variables rather than the actual tapes. 11 The Mercy method uses MAC and HL, and PXM uses MAC and height. 12 , 13 Maximum measurements were assumed for those beyond the limits of those methods (Mercy: HL 39 cm, MAC 40 cm; PXM: height 200 cm). The LMS method used sex‐specific tables of data for weight according to MAC. 6 For each of the methods, formulae were created in Microsoft Excel to generate weight estimations for all individuals in the study.
