Novel type of references for weight aligned for onset of puberty - using the QEPS growth model.

ABSTRACT:

Background

Growth references are traditionally constructed relative to chronological age, despite inter-individual variations in pubertal timing. A new type of height reference was recently developed allowing growth to be aligned based on onset of pubertal height growth. We here aim to develop a corresponding reference for pubertal weight.

Methods

To model QEPS-weight, 3595 subjects (1779 girls) from GrowUp₁₉₇₄Gothenburg and GrowUp₁₉₉₀Gothenburg were used. The QEPS-height-model was transformed to a corresponding QEPS-weight-model; thereafter, QEPS-weight was modified by an individual, constitutional weight-height-factor. Longitudinal weight and length/height measurements from 1418 individuals (698 girls) from GrowUp₁₉₉₀Gothenburg were then us
