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.
