Abstract

Children who experience puberty ‘off-time’ (much earlier or later than their same-sex, same-age peers) are at increased risk for mental health problems, including internalizing and externalizing problems, eating disorders, and substance abuse. The age of puberty onset has also decreased over the 20th century in high-income countries, with similar trends observed in low- and middle-income nations. A complex interplay of risk and protective factors is likely to determine pathways to off-time puberty and mental health problems in CYP, necessitating an interdisciplinary approach.

The aim of this project was to better understand pathways to mental health outcomes from childhood to late adolescence/early adulthood. This project will achieve this by maximising the use of existing datasets of children and families who participated in longitudinal studies in the UK and overseas.

The collection consists of the R source file used to run the analysis for using SITAR (SuperImposition by Translation and Rotation) to estimate age at peak height velocity in the Millennium Cohort Study.
