df, degrees of freedom; SE, standard error; B, unstandardized regression coefficient; β, standardized regression coefficient; R², proportion of the variance in the dependent variable accounted for by the covariance, ΔR², the increment in R².

^aThese regression coefficients are from the final model that contained all the covariates. Dichotomous variables for income and education were coded “1” if the person fell in that category and “0” otherwise. Participants with missing data were listwise excluded.

^bThe unit of measure for the dependent variable is % w/v.

^cAll but 2 of the parents are the mothers of the children.

*P < 0.05.
