HEI-2010: Healthy Eating Index 2010;
SCAN: Study on Children’s Home Availability Using Technology;
Home-level HEI-2010 scores were based on two home food inventories from each household (n=97) to estimate home-level diet quality.
Individual-level HEI-2010 scores were based on 24-hour diet recalls (two recalls per person) to estimate individual-level diet quality for parents (n=97) and children (n=97), respectively.
Regression coefficients compare the grocery shopping categories reported in the table to the reference group (i.e. once/month) by presenting the mean difference in HEI-2010 scores adjusted for covariates. Covariates in the model are race/ethnicity, parent body mass index, income level, total number of household members, marital status, food security status, food assistance status (SNAP), transportation mode to grocery store, family meals prepared away from home, and number of stores visited per shopping trip.
