Standard errors are in parentheses.

^***p<0.01

^**p<0.05

^*p<0.10

Weighted quantile regressions with robust standard errors.

Dummies for SNAP-eligibility, ARRA, and SNAP*ARRA are further interacted with education category (high school and lower vs. more than high school). The table reports the triple interaction between SNAP, ARRA, and low education.

Models also control for age, gender, education (high school/ged; some college; college grad; missing education), employment status, race/ethnicity, the ratio of household income to federal poverty threshold, household size, family structure (divorced/separated/widowed/never married, missing marital status), quarterly time trend, and state fixed effects. SSB stands for sugar- sweetened beverages. SoFAAS stands for the solid fats, alcohol and added sugars component score of the HEI-2005. HEI-2005 stands for 2005 Healthy Eating Index.

The percentage change is calculated as exp(β) – 1.
