HbA_1c by food insecurity and food access

	Adjusted baseline HbA1c, % (95% CI)	Difference (95% CI)	P	Average slope [change per month in HbA1c, % (95% CI)]	Difference in change per month in HbA1c, % (95% CI)	P
Food insecure	7.6 (7.3–7.9)	0.6 (0.4–0.8)	<0.0001	0.0002 (−0.01 to 0.01)	−0.003 (−0.01 to 0.01)	0.50
Food secure	7.0 (6.8–7.3)			0.003 (−0.001 to 0.007)
Low food access	7.4 (7.1–7.7)	0.2 (−0.2 to 0.5)	0.33	−0.003 (−0.02 to 0.001)	−0.007 (−0.02 to 0.001)	0.07
Adequate food access	7.3 (7.0–7.5)			0.005 (0.0004–0.009)

Data are means, and the difference in mean HbA_1c was calculated using least squares means from the regression models presented in Supplementary Table 2 (for food security) and Supplementary Table 3 (for food access). Food access defined using the 1 mile in urban areas and 10 miles in rural areas definition. In addition to the exposures of interest, models were adjusted for age, age squared, sex, race/ethnicity, education, insurance, health literacy, language, age at diabetes diagnosis, baseline Charlson comorbidity score, insulin use, statin use, number of outpatient care visits, census tract median family income, census tract poverty rate, and census tract vehicle access.
