SITAR-d: extending the SITAR growth curve model to allow for variability in post-pubertal velocity

Key Points

The study aims to improve the SITAR model for evaluating post-pubertal growth variability and its link to weight gain.
Extended the SITAR model to include variability in growth velocity post-puberty.
Analyzed early adult weight gain using growth data across a population.
Assessed the impact of delayed development on height measurements.
SITAR-d effectively extracts weight gain patterns in early adulthood.
Height measurements showed enhanced consistency with growth data under SITAR-d.
Identified a subgroup of individuals with delayed development affecting growth metrics.

Abstract

SITAR-d is useful for extracting early adult weight gain from growth data, potentially an important risk factor for obesity-related morbidity. Height also fits better with SITAR-d, reflecting a minority of individuals with delayed development.
