Fig. 1: The distinct trajectory patterns of body mass index from early to late adulthood in the DCH-NG Cohort.

Four distinct patterns were identified through latent class growth modeling, with the percentage and number of participants in each group indicated. Dashed lines represent class-specific mean predicted BMI trajectories from the best-fitting model; shaded horizontal bands indicate conventional BMI ranges (for reference only). The number and percentage of participants in each latent class are provided in the figure legend. BMI body mass index, DCH-NG diet cancer and health–next generations cohort.
