Trajectories of Change in Obesity among Tehranian Families: Multilevel Latent Growth Curve Modeling

Figure 2

Model strategy building on each anthropometric measurement. Mean trend analysis (step 0); step  1: the conventional latent growth curve was assessed with linear time scores (i.e., 0, 1, 2, and 3 for four phases, resp.); step  2: evaluating shape (linear or quadratic), as a best type of trajectory of changes on the multilevel framework; step  3: conditional multilevel latent growth curve modeling with preferred time scores in step  2, adjusting for age and gender covariates. ANOVA, analysis of variance; MLGCM, multilevel latent growth curve modeling.
