A-F Modifiers of Predicted Weight Trajectories Across Age (A, C, E) and Time since Immigration (B, D, F) for Hispanic/Latino Adults from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Baseline Examination (2008–2011). Mean weight trajectories and 95% Confidence Intervals (CIs) across age shown in A, C and E represent adjustments for the following weighted covariates or interactions with their displayed categorizations: age at examination (except for A that plots the average for a 30 year old), proportion male, born before 1980, nativity by age at immigration combination, background by study site combination (constructed to represent combinations of more than ≥100 individuals), and digit preference for self-reports ending in 0s or 5s. Mean weight trajectories and 95% CIs across time since immigration in B, D and F represent adjustments for the following weighted covariates or interactions with their displayed categorizations: age at examination (except for B that plots the average for a 55 year old), proportion male, immigration before 1980, age at immigration, background by study site, and digit preference for self-reports ending in 0s or 5s. Pre/post immigration weight trajectories varied by the categorical variables shown in B, D, and F (Chi-square p-values being <0.0001 to 0.01). In addition, F show the average trajectory for the mid-point of each age at immigration category. The Chi-square test of difference in the pre/post immigration slopes was significant in all cases in B, D and F (p<0.0001). The tips of the colored triangles in all panels signify the point (if any) in the weight trajectory where the average body mass index rises above 30kg/m2, given the weighted mean height of that particular subgroup. Examples of how to calculate population-level weight change, or the effect of demographic or sociocultural factors, based on the final model coefficients are provided as part of Supplemental Tables 3–4
