Per capita GBD purchases (grams/person/day) using household sampling weights were calculated as follows: household average quarterly purchases/household size/91 days.
The coefficients of the log-linear model are interpreted as the percent change in purchases using 2005 as the reference year and were adjusted by covariates for race/ethnicity, federal poverty status, education, household composition/size and geographical location.
Indicates a significant difference (P<0.05) in the percent change in GBD purchases from 2005.
