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.
