¹Multivariable linear regressions were conducted by using bootstrapping, and adjusted results were obtained by controlling for sex, age centered at 50 y, educational attainment category, and estimated poverty threshold to income ratio. Bias-corrected CIs are reported. A spline term on day 15 was included. Higher total HEI scores correlate to higher compliance with the 2010 Dietary Guidelines for Americans. Higher scores on refined-grain and empty-calorie component indicated low consumption, and higher scores on the dairy and whole-grain components indicated higher consumption per 1000 cal. For example, the HEI dairy–component scores ranged from 0 to 5. A score of 5 represented consumption equivalent to ≥1.3 cups/1000 cal. HEI, Healthy Eating Index; LL, lower limit; SNAP, Supplemental Nutritional Assistance Program; TSSD, time since Supplemental Nutritional Assistance Program distribution; UL, upper limit.
