Table 1 Eating behaviours and characteristics of the subsamples of the Avon Longitudinal Study of Parents and Children (ALSPAC) that were included in the construction of the eating behaviour trajectories using latent class growth analysis27 and the subsample that also has an available metabolic profile at age 16 years.
