Descriptive statistics of key study variables by socioeconomic status. Note. Means for each subsample at each time for each variable are presented by the bars, standard errors are presented around the means. Within a measure “block” the lighter color indicates the lower SES group, whereas the darker color indicates the higher SES group. A change in color scheme indicates a new measure. Data shows participants with relatively lower socioeconomic status appear to have potentially slightly elevated exposures to toxins and higher mean scores on perceived maternal stress
