a

Variations in sample size for dietary variables due to removal of outliers 3 standard deviations above the mean.

b

Total Healthy Dietary Practices was calculated as the total number of the 8 dietary recommendations the participant met; for those participants who were missing up to 3 dietary variables, this variable was calculated as the percentage of recommendations met for all valid variables multiplied by 8 (participants missing more than 3 dietary variables were also coded as missing the composite variable.)

c

This item, “It’s important to me to prepare healthy meals,” had response options ranging from 1 (“strongly disagree”) to 5 (“strongly agree.”)
