Note. Log coeff. – Logistic coefficient, Low – Low trajectory, Increasing – Increasing trajectory, High – High trajectory, NH – Non-Hispanic. NH White is the referent group for the racial/ethnic group comparisons. Each predictor/covariate was grand mean-centered except for nativity, physical activity, dummy variables for race/ethnicity, and sex, smoking variables to aid in interpretation. All estimates are unstandardized. All covariates were included in this model but only simple effects are presented here for clarity. Significant simple effects are bolded. For the education, the low level was 1 SD below the mean (9.11 years of education), the medium level was the mean (12.39 years), and the high level was 1 SD above the mean (15.673 years). In contrast, for wealth, the low level was the lower quartile ($50,000.00), the medium level was the median ($143,000.00), and the high level was the upper quartile ($352,000.00).
