Replication Data for: A longitudinal analysis comparing the proportion of children with excess weight before and during the Covid-19 pandemic

The aim of this study was to see if there was an increase in the proportion of children with excess during the pandemic above what might normally be expected. This dataset was used to compare changes in BMI category in a sample of children whose height and weight was measured during the Covid-19 pandemic, with a sample of children with BMI measurements before the pandemic.
